Brooke glanced up once more at the ads on the bus. They had caused no end of mirth when they first came out, but people snuck glances at them now, and the smiles had gone. You could see some people getting quiet and thoughtful when they stopped to take them in.

One showed an attractive woman looking at a pretty schlumpy-looking middle-aged guy. "You wouldn't want to marry him, but he might be the one!" The thought bubble in her mind showed a picture of her holding a gorgeous infant, showing the age-old bond of love between mother and child. Brooke felt a pang in her heart looking at that baby.

Another showed a handsome man looking at a kind of pudgy woman with glasses, an average face and a studious expression. This one showed in the man's mind a picture in the gray of a dim room with her laid out on a bed, looking hungrily and expectantly at him. Her breast showed and she had her hands between her legs, presumably holding her pussy open for him to stick his dick in. It was pretty explicit, thought Brooke, but at least her pussy and the guy's dick didn't actually show. The caption read, "Remember this part? She wants it! No strings attached! Ask her!"

Another showed a smiling but plain-looking woman examining her palm pilot as a not-very-attractive guy looked on. "Make that one-night stand count! Choose the right time of month!" Another showed a woman lying back with her legs crossed in an opulent room. She was holding up a little girl's dress and looking at it with a smile. "No worries about money again! Free childcare!"

The one that had caused the most controversy showed a woman in a dimly lit room with her butt up in the air. A man behind had his hands on her hips, obviously doing her doggy style. She held a vibrator up between her legs and was obviously in the throes of orgasm. In abstract view it showed another man with a smile, his hand surrounding his erect dick so you couldn't quite see it, getting ready for his turn. Another showed a man on his back with a vague grin on his face, a man who had presumably just done her. The caption read: "Forget what your mother said. It's what your body was meant to do! Become a connoisseur of men's organs! Of the different sounds they make when they give you their gift! It feels really good! Choose the reasons you like, but when that time of month comes, be a heroine!" And in another panel it showed the woman with a cute baby, surrounded by fawning, happy men and women. To be a slut was now patriotic.

She had always assumed she would get married, but her dating life had not been promising lately. She enjoyed the times she spent with her current boyfriend Hal, but she thought of it as a pleasant interlude only.

She also knew she wanted a baby. And those posters showed how to get a baby -- if you were lucky. The sooner she started, the better her chances.

Stan was a little nervous when he knocked on Brooke's cubicle door. They worked together in the call center. He had asked her out a year before, and she had politely put him off. But this was different.

"Hey, Brooke."

"Hi, Stan."

"Ummm. I was wondering. You know all those ads on the buses?"

A little surge of fear and excitement raced through Brooke. He was probably going to be the first one to ask to fuck her. Not date her, fuck her. That was the right term. It's what she really ought to be doing, letting him fuck her. So she gave him an uncertain smile. "Yes..."

He blurted out, "I'll do you if you'd like. Just sex, nothing more." After a pause, "It's patriotic!" he added nervously.

He was crude and could be sarcastic. But his body made sperm cells. They might be the right ones. He was actually decent looking, so the physical act might be exciting.

"Sure," she said. Listening to herself she realized she didn't sound enthusiastic, and she noted she would have to work on that in the future. She didn't want to hurt a guy's feelings when he was being patriotic.

"Great! How would next Wednesday be?"

"Ummm. It's got to be a particular time of month, right?"

"Right, damn, I forgot. This whole thing is weird."

On a whim she decided to be a bit playful. "If we do it some other time, then it's not the new kind of 'just sex', it's the old kind of 'just sex'."

He smiled a little.

"It will be about two weeks," she said as Stan was walking away with a grin on his face. Brooke reflected that if he bothered to do subtraction Stan now knew that she was having her period. Oh great. Well, in two weeks he would learn about her reproductive system in a much more intimate way. She figured she would buy one of those thermometers to track ovulation. Might as well get the timing right if she was going to start spreading her legs.

As long as she was in slut mode, she figured she would use the momentum to ask a guy. She felt almost numb with nervousness when she went around the corner to Bob's cube. Despite herself, she couldn't help coloring when she said, "Hey Bob, will you fuck me in two weeks? Do your duty to humanity?"

Bob stammered. "Oh, Gee."

Was it surprise, or did he not want to do her? It would be really humiliating to think a guy didn't want to fuck her.

"Umm, sure! You just took me by surprise."

"Remember what it says on the poster, it still feels good even if I'm a dog," she said.

"You are not a dog!" he said, a little too loudly. There were a few suppressed giggles and snorts from nearby cubes.

They were both flustered. That comment didn't reflect well on either of them.

"About two weeks. I'll tell you exactly when."

Brooke appeared at Stan's cubicle door in just twelve days. His heart surged when he saw her.

"I guess I'm supposed to show you this," she said, handing him a little slip with the date and a stamp saying "Clean!" It was from one of the free STD kits. He smiled and said he would bring his own that evening. They agreed she would come to his place at six.

"Can I get you a Coke or something?"

"Thanks, but I don't have long." She was due at Bob's at 7:30. A slut.

"Oh, OK," he said. He led the way back to his bedroom, and seeing no other signals from each other they stripped, instinctively turning away from each other. She lay on the bed and on instinct pulled a sheet over her to hide her nakedness. Would he find her body acceptable? Odds were that since he asked her out way back when he thought she was attractive, but all women are insecure about these things deep down. As he turned she could see he was mostly erect already. An average-looking cock. Not that she really knew. She had had a total of four lovers up to this point in her life. By this evening it would be six.

An image flashed through her mind of an endless series of cocks. If she stayed with the program, her total of lovers -- or at least men who shoved their cocks into her -- would increase rapidly for years. She saw a graph with an arrow pointing up at an angle -- Ooo, very Freudian, she thought.

Brooke was on the slender side, but she thought her hips were too big. She had long dark hair, a round face with a straight nose of moderate size and warm brown eyes. As he raised the sheet to slide in next to her, Stan glimpsed what she usually kept in her bra. They were luscious, with pale pink aureoles and modest nipples that were at the moment small. He could see her nakedness trailing away beneath the sheet, but didn't want to stare. His erection got even harder.

She put her hand between her legs and started massaging to get herself ready.

After a few seconds he said, "Can I do some of that?" leering a bit. Or was it just honest desire?

"OK, you can try," she said. She hadn't really been planning on letting him do that, but the boundaries of 'just sex' were unclear.

He was good. It wasn't the way she usually did it, but in less than a minute her body caught onto his rhythm and she felt really good.

"Am I allowed to, uh, suck your nipples?" he asked.

She hadn't been planning on allowing that either, but now she had to admit she was excited by the idea. He used a technique she had never experienced before, sucking in little bursts, resting between. Something about it felt profoundly right. The juices flowed freely in and all around her pussy, the entire area engorged and quivering.

"OK, I'm ready," she said, trying not to sound quite as hungry as she felt.

He rose above her and he let her guide him into her. His body was quite impressive, with rippling arm muscles and a six-pack that was now in evidence as he started in and out at a very nice pace. He had a grin more of conquest than tenderness, but ... well, she didn't need tenderness, not for this.

His cock was apparently longer than any of her other lovers', because she felt it bump something way in deep, and it felt good. The bumping against her swollen clit and the spot deep inside were like stereo.

This was 'just sex', but it was feeling terrific and she let herself go, panting and moaning. She was on the edge. "A little faster," she gasped. He sped up. Her girl animal took in the boy animal's muscled body and deep-throated grunts and face slack with pleasure. She felt his throbbing member filling her and pressing that newly discovered inner part of herself. All that combined with the clit bumping and labial tugging was enough. Her body convulsed with pleasure and release as she gasped. A second later she felt his cock get even bigger and then felt it twitch and knew that at that moment his sperm was shooting into her. Stan's convulsion inside her extended her orgasm. He stayed inside her until she was on firm ground again, then pulled out and lay panting beside her.

It had been the best sex of her life. By far.

No protocol existed in the new regime of 'just sex' to calculate the appropriate duration of afterglow, but she decided not to worry about it. She let herself relax snuggled up against him.

She started awake as Stan whispered, "Did you say you were meeting a guy at 7:30?" The clock showed 7:25. Stan was considerate to remind her of her commitments. Maybe she had misjudged him.

She didn't want to go -- she wanted Stan again. So maybe she would be a little late to Bob's. She slid her hand down to Stan's cock, and within a few seconds he was fully hard again, and his body language confirmed that he was eager to do it again. She was still pretty wet from before, but his fingers did their magic to juice her fully.

She said, "I guess this is the old kind of 'just sex' now, not the new kind, but it's still 'just sex', OK?"

Stan grinned. She rolled onto her back and he slid in and pounded away. This time he gently lifted her legs up and she held his head between her calves. She had a slightly different but equally magnificent orgasm.

She liked the idea of Stan's sperm up inside her on her fertile day when they just might make a baby, however unlikely that was.

But the other man waited, so she sighed wearily as she got up and dressed. As for Hal, her boyfriend, she couldn't see any point in their staying together any more. It felt like an afterthought.

"Any chance you'd like to do it again some time?" Stan asked. She couldn't help giving him a flirty smile. She had this sneaking suspicion she would want to do it again with Stan. Maybe a lot.

For now, on to the next dose of sperm.

Obstetric practices noticed it first. Starting in April of 2028 women stopped calling. They stopped calling because they weren't getting pregnant. Even in parts of the world that do not have obstetric practices the same phenomenon was clear -- women didn't miss their periods.

It was obvious that without pregnancies the human species was doomed, but there were reasons not to panic. Science was very good at solving medical problems, and the pregnancies might just resume on their own.

What scientists found was essentially nothing. There were no detectable changes in the reproductive process, whether looking at men's bodies, women's bodies, their tissues, or their cells. The problem was simply that the sperm wiggled against the eggs, but the eggs never let them in.

One hopeful sign was that there still were occasionally women who got pregnant. There was fewer than one pregnancy for every 100 there had been before, but there were still a few.

In contrast, no one observed a single fertilized egg in a test tube, and artificial insemination produced a grand total of zero pregnancies.

Investigation focused on what factors were responsible for the very few pregnancies that did occur.

As expected, the more often a woman had sexual intercourse during her fertile period, the more likely she was to become pregnant.

They also found that a variety of different partners led to a much higher pregnancy rate. The effect was far larger than could be explained as compensating for occasional male infertility.

An unexpected and disturbing finding was that rape was slightly more likely to lead to a pregnancy than an ordinary act of intercourse. It was a small effect, and government reports always equivocated. The authorities said that different and unusual acts of intercourse were more likely to result in pregnancy, and that rape was just a special case of an unusual and different act of intercourse.

As time went on and there was no medical solution and few promising avenues of research, the gravity of the situation began to sink in. Anger and fear were loud, while despair and resignation were quiet but just as powerful.

Before six months had passed there was a noticeable increase in pregnancy which the scientists determined was simply the result of couples shifting from trying to prevent pregnancies to trying to achieve them. Contraception use plummeted, more couples had sex, and there was an effort to time the intercourse to the woman's fertile period. But the increase was small. Extrapolating the observed trends, the scientists estimated that pregnancies might reach one and a half percent of the pre-crisis levels. Just trying harder to make babies in the usual manner was not going to solve the problem.

The most promising opportunity for increased fertility was in increasing the variety of sexual partners. Promiscuity. There was a bit more sleeping around when people learned that it helped, but not very much. Promiscuity within a committed relationship when trying to achieve pregnancy is very unusual.

The government set in motion a number of initiatives to encourage more sleeping around, especially by women during their fertile period.

The production capacity for ovulation-detection kits was increased. Better and easier-to-use models were developed, and they were offered for free. If a woman was going to take another sexual partner outside of her relationship, it ought to be done at a time when it might matter.

Sexually transmitted diseases promised to be a huge problem. Condoms were of no use because the idea was to deliver semen into vaginas, not keep it carefully confined and drag it back out.

There was a huge effort put into STD detection. Better kits were invented, ones that did not require lab work, and they were made available everywhere, for free.

But by far the best solution to the STD problem was the Sykes polymer. When applied monthly to the penis it completely prevented female to male STD transmission, and unlike the condom it enhanced male sexual pleasure instead of diminishing it.

There was some indignation that this solution protected men but not women. But most people came to understand that when men were not getting re-infected and were then aggressively treated, women stopped getting re-infected too. The polymer was of course made available for free and its use encouraged.

A great many people have no interest in making babies and are content to remain childless. To encourage them to get involved, financial incentives were offered. The government could easily afford to offer $50,000 per live birth.

It took two years before the ads that Brooke saw on the bus were created. Despite a huge controversy, the decision was made to push them heavily. They showed up everywhere: buses, magazines, websites, billboards, and TV shows.

It had been no easy matter for Brooke to get herself to sleep with Stan and Bob. As Brooke arranged her liaisons, much of the anxiety of the human mating dance remained. Did Bob find Brooke attractive? He had accepted, but was he just saving her the pain of rejection? Stan had also asked Melissa if she wanted to sleep with him. Although she did her best to be polite, she turned him down, to Stan's dismay. And ideally Brooke should have had sex with five men during her fertile phase, not just two. For best results, while she repeated the exhausting ordeal the next month it should be with five different men, not the same five.

Brooke was attractive and reasonably self-assured. It was far, far harder for many others.

Sabrina was at the supermarket looking over the fish when her cell phone rang.

"Yes?" she said.

"We have a mate for you." A little twinge of fear surged through Sabrina. She had notified the switchboard that morning when her ovulation test was positive. Last month five men had come to her house in the evening and she had had sex with all of them. It was a surreal memory, and she was preparing herself for the same sort of evening. But why was she being called in the grocery store?

"Now?"

"Yes. Remember, we're trying to shake things up. Try to spice things up to get that rape effect without the rape.

"When he shows up, go into the back and find some place to have sex, OK?"

"Are you kidding?"

"No." She knew this sort of thing was possible. They had discussed it during orientation. But the back of a grocery store?

Just then someone tapped her on the shoulder and she turned to find a man, maybe 5'8" tall, with a shaved head, an ample belly, and a number of tattoos on his bare arms. At least his smile was friendly. Sabrina was 5'6", 38 years old, and not physically remarkable. She had shoulder-length brown hair and brown eyes.

She tried to hide her dismay. Perhaps sensing it, he recited the mantra of the program, the first line of defense against awkwardness: "We're just trying to make a baby."

"We're just trying to make a baby," she repeated, managing a smile.

"In the back of the store," he said, heading towards the hanging plastic strips that defined the border that customers were not supposed to cross. She followed.

"How are we supposed to find any privacy back here?" she asked.

He was looking around actively. He found the employee bathroom, and looked uncertainly into it. She only needed one glance before saying, "I don't think so," and they continued their search.

He pointed to the back of an aisle that was out of the way and motioned her to follow.

"Not in public," she said. The program encouraged couples to not worry about being seen, figuring that a little exhibitionism might help with pregnancies too. But she wasn't ready for that.

"Hold on," he said. He took down a few cartons holding breakfast cereal boxes and built a sort of makeshift wall they could go behind. At least no one would see them unless they actually went down the aisle to investigate. But how would they actually do it? The floor was not appealing, nor was doing it against the wall. He brought down one more box, this one holding Wheaties, an odd fact that stuck with her. He placed it behind their little wall. "Bend over?" he said.

He was proposing to take her from behind as she leaned over a cardboard box, behind a makeshift wall of cardboard boxes behind the scenes in a grocery store. "I want a baby," she said to herself. The unusual was supposed to help. She took a deep breath and said, "OK."

He pulled pants and underpants down to reveal a cock which was not flaccid but not hard either. He started stroking it. Sabrina decided she could keep her skirt on if she stepped out of her panties. She opened her purse and took out the vibrator, then reached up under her skirt and applied it. She felt her vulva swelling, her pussy lengthening, and felt herself getting wet.

He was stroking away, but his erection wasn't there yet. She smiled at him in encouragement. Procedure here encouraged her to give him some head, but there were other things to try first. She gently took the end of his cock in one hand and with the other applied her own vibrator not directly to his cock but to her hand as it cradled his tip. That did the trick and soon she had a hard member in her hand. He smiled and said, "Thanks."

Sabrina leaned over the box and flipped her skirt up. He came up behind her and spread her pussy lips -- too hard, it hurt a little -- and plunged in. She wasn't terribly wet, but it wasn't going to hurt. He thrust back and forth fast and hard. She heard footsteps coming down the aisle, and said "Shit!" but he didn't stop and she didn't want to fight with him. "I want a baby," she said to herself.

In about 30 seconds he dug his fingernails into her butt (ouch!), slowed his pace just a touch and did a couple really deep strokes with a big grunt. That was what the whole thing was about, getting his sperm up her pussy. Just as he pulled out she heard snickering and quickly flipped her skirt down, feeling mortified. A young guy had come to see why the boxes weren't on the shelves any more and had watched the end of their coupling. The guy with the tattoo gave him the finger along with a menacing look and the kid quickly disappeared. She felt hot from shame and embarrassment, but repeated to herself, "I want a baby." When they had both dressed he started putting the boxes up on the shelves where they had come from. She did one herself.

"Thanks for trying to make a baby," she said.

"Thanks for trying to make a baby," he repeated.

He headed one way and she returned to her cart in front of the fish, aware of her engorged sex organs and the semen that was dripping out onto her panties.

"A pound of haddock, please," she said, taking a deep breath.

Frank took his place at the podium. The lecture hall at the Center For Disease Control was packed. The lights dimmed as his first slide came up. After some preliminaries he got to the meat of his talk.

"Today I present the results of the first Systematic Mandated Pairings experiment, called 'SMP'. We found 273 young women and 324 young men to take part in the experiment. They were volunteers but were aware they would be receiving $5,000 if they carried out all of the matings that were suggested to them, though they were allowed to miss a few. A total of 262 young women and 287 young men completed the entire eighteen months of the study.

"The young women used their ovulation kits, and 85% of the time they reported the beginning of their fertile periods accurately. This number is not bad, but clearly there is room for improvement. Dr. Fitzhugh's work on detecting ovulation automatically by way of a sensor probe inserted into the hypothalamus could be very helpful in improving that statistic.

"The computer model we had was quite simple. We tried to get as many different male-female matings as we could over the eighteen months of the study. Hired staff manned the cell phones to direct the men and women to their matings.

"Having screened the applicants for basic attractiveness, both partners attempted 94% of the suggested matings. Male performance difficulties reduced the number of successful intra-vaginal ejaculations to 88%. Overall, these women received on average 3.8 intra-vaginal ejaculations per fertile period.

"The bottom line number, of course, is how many pregnancies were achieved. The answer is 12." An excited murmur rippled through the audience. "Ten of those babies have now been born, and the other two are due within the next two months.

"Those results are quite promising. The next question on everyone's minds is what characterized the successful matings. As you all know, it is very hard to find anything definitive with a mere 12 data points. But if we rate the circumstances of matings on a 'novelty' scale, then novel situations seem to be associated with more pregnancies, but the difference is not statistically significant (p < .30).

"While twelve pregnancies is excellent, consideration of the personal situations of our volunteers paints a more sobering picture. Three married couples were in our SMP study, and those marriages show no signs of undue distress. Eleven married men participated without their wives. Two now report marital difficulties. Four married women volunteered for the study without their husbands. One dropped out, and two of the remaining three report that they are headed for divorce. Setting aside cases where the husband volunteered for the program himself, that leaves a single married woman who participated in the SMP experiment and whose marriage survived.

"The evidence is anecdotal. But it is easy to speculate that we are running up against a fundamental social limitation: Women cannot both remain in a closely bonded relationship and engage in the systematic and frequent promiscuity that is the key to successful reproduction."

Malcolm Smith was the President of the Mormon Church, and he was now granting an audience to Xavier Chen.

He had read the executive summary of the report with skepticism, but somehow this young man's passion was getting through to him.

"To summarize, sir: Without another major breakthrough, humanity is heading for extinction. Literal, total, biological extinction." Xavier's face as he delivered those words jolted Smith.

"There are liberals and libertarians who are engaging in the sort of rampant promiscuity that gives the best pregnancy rates we have observed anywhere. These are precisely the people that the conservative churches have reviled for so long.

"What we need -- what humanity needs -- is a church that is known for its social conservatism to come out in favor of the rampant promiscuity needed for an adequate pregnancy rate." Smith wasn't sure of much in this whole matter, but he was certain that a better phrase than "rampant promiscuity" would be needed to describe the salvation of humanity.

"Mormonism is a unique combination. You have a fierce commitment to family and children. A graying Mormon faith without children is no longer a Mormon church." Once again Chen's delivery hit Smith at a deeper level.

"A great many Mormons follow church teachings, even when they are inconvenient." Smith thought again of the despair of his years on his Mission, a despair that was so common to the young men.

"And you, sir," said Xavier, pointing at Smith in a way that he would ordinarily consider impertinent, "can receive messages from God that influence how millions will behave."

"You, sir, may be the single person who holds the fate of all of humanity in his hands." Xavier's eyes burned. The young man looked at first one hand, "Extinction," and then the other, "or Survival".

Smith lay awake that night. Although he was now the head of the church, he had never expected to receive any revelations from God. The closest thing he had to visions was images of ten-year-old boys with their pants down, visions accompanied by impure thoughts. To his consternation, regret flickered through his head that he would never see such a thing -- those Catholics, sigh.

Xavier wanted Smith to say that rampant promiscuity -- OK, let's work on that. How about "many-fold love for God's creation"? Xavier wanted Smith to say that many-fold love for God's creation was a good thing.

He thought long and hard. It would ruin his reputation. He might well be forced from his position. He had gotten where he was by working the system, playing politics, playing it safe. It would surely cause upheaval in the church. But that image of graying Mormon communities without children made him shudder.

As he was just drifting off to sleep a thought flashed to his mind. Xavier might be an emissary from the divine! Smith thought of the way his eyes burned, the way he spoke insolently but Smith had found himself captivated. It was probably an illusion, his everyday self cautioned. But as Xavier's face conveyed as much as his words, without radical measures humanity was doomed. It was time for a leap of faith.

Smith clenched his one hand, then let it relax and clenched the other. "Survival," he said.

Smith's decision was of monumental importance. In later years scholars wrote bookshelves full of analyses and speculation. Just as Jesus the Jew gave rise to the far more influential Christianity, Smith of the Latter Day Saints would be granted nearly divine stature in the Church of Survival.

Smith's impure thoughts about young boys surfaced in hints in the journals published 50 years after his death. Scholars speculated that those impure thoughts tipped the balance away from rigid morality to sexuality, to forgiveness of sexual trespass, and to life itself.

While there was turmoil and a schism, 68% of Mormons followed Smith's lead. Women and girls gritted their teeth as they raised their skirts to strange men in God's name. Men gnashed their teeth and shuddered as they considered this abomination against their womenfolk -- an abomination that God had ordered. They also experienced it directly with different emotions, since they were the ones poking inside the panties of other men's daughters and wives.

As Xavier had foreseen, the shift in the Mormon church sent shock waves throughout the conservative religions. There were schisms everywhere. For at least a sizeable minority in every denomination, "Be fruitful and multiply" won out over "Thou shalt not commit adultery."

Denominations formed their own SMP programs. Different rules for how to match partners yielded different degrees of effectiveness. That in turn provided data for better ways to arrange future programs.

Every city in the country had at least one SMP program, although a tiny fraction of the population was enrolled.

---

It was Xavier who had been chosen to address the Congressional committee. He was the most charismatic of the radicals.

"It has been six years since the pregnancy crisis began. Time is running short for the human species. We might in theory have another 10 or even 20 years, but remember that no one expects any particular step to solve the problem instantly. We are still on a slow, agonizing path. But we need to take the next step. We have a ditch to cross, and it will require a leap.

"Last month the last doubt was removed and a strong hypothesis became irrefutable fact: The higher the percentage of people in a city or town who are participating in a Systematic Mandated Pairing (SMP) program, the higher the pregnancy rate.

"What we need is an enclave where everyone -- 100% -- are participating in the program. And 'enclave' isn't the right term. It has to have a critical mass -- 100,000 people is a minimum."

"We need a safe haven where participants can be open and proud about their choice without the fear of disapproval, harassment, or even violence.

"Coercion to have sex within an SMP program is of course unthinkable." Though ultimately, Xavier reflected, I would support it. Will I be here in 10 years making exactly that case?

"People will be free to leave the city, of course. But having made the choice to join, the decision to leave will not be made lightly. Social pressure within the city will tilt in favor of staying in the program and the material benefits will be substantial. We want to give people every opportunity to work through an initial adjustment period and come out the other end committed to the SMP program -- to survival!

"The major city with the highest SMP participation rate is Salt Lake. Malcolm Smith's historic revelation has led a large percentage of Mormons to participate, and the momentum has attracted and convinced others. 38 percent of the city residents participate."

He paused and shifted his tone.

"The transformation of Salt Lake will be profound."

"We will require any people who do not participate in the program to leave and we will take their homes by eminent domain. They will be very generously compensated. Nonetheless, this is by far the most difficult and controversial step we are proposing.

"All those homes will be occupied by those many people throughout the nation who want to participate in this grand new experiment.

"Agreeing to the transformation of Salt Lake City is a politically difficult step. It is the most difficult step a politician has ever been called upon to take. But consider your place in the history books -- oh, but wait! If you stick with business as usual, there will be no history books. There will be no one in 100 years to read the books. We will be extinct."

A momentary eerie silence descended upon the committee chamber.

Salt Lake City

The last of the property has been taken by eminent domain. The last die-hards have had their hands pried from their front doors and been dragged away. They have been offered plenty of money to afford comfortable accommodations in other cities. The immigrants have poured in to occupy those homes.

The last of the protesters are gone from the city, and the guarded perimeter is in place. Protests still occur, but not in the view of Salt Lake residents.

Forty-four percent of the city's population elected to stay. The selection process took into consideration some variables related directly to the SMP program. Not surprisingly, more men than women were interested in a life of brief sexual encounters, so the excess men were turned away. Married couples were highly prized. Marital bonds will feel stress, so couples who volunteered are a vital bulwark in maintaining the institution of marriage. The most coveted of applicants were married couples with children who would come of age in the new environment --especially daughters.

There are no potholes. There is fresh paint everywhere. Rent, groceries, and other necessities are heavily subsidized. Jobs are plentiful. There is comprehensive and enlightened childcare available, and although there are few babies now the system is geared for rapid expansion. Because there were far more applicants for immigration than spaces, the new residents are predominantly energetic, enthusiastic people with a positive outlook on life.

There is one price everyone in the city has agreed to pay: when the central authority tells them where to go and who to mate with, they go and they mate, at least most of the time.

Technology has been at work. Instead of the cell phones used in earlier SMP experiments, each person wears a dedicated device behind their left ear. It is called a Reproductive Assistive Device, or RAD for short. All the residents of Salt Lake City are encouraged to wear them, even the old women who are past their childbearing years. It is a symbol of allegiance to the noble project of the city.

The banks of volunteers manning cell phones have been replaced by a single seamless computer network. Unprecedented breakthroughs in artificial intelligence have created a very impressive system. The RADs offer to their wearers far more than instructions on who to mate with.

Potentially the biggest payoff of the sophisticated computer network and its RADs is that they allow a massive scientific experiment that could allow for further dramatic increases in fertility.

It has been known from the beginning that unusual sexual practices -- including, to everyone's consternation, rape -- are associated with higher fertility. With the ability to dictate matings not only of particular males and females but the particular circumstances of those matings, enormous amounts of high-quality data will be available. Hypotheses can be generated, tested, and refined, and then results can guide new experiments as part of an iterative cycle.

The experiment is finally in place.

Gerald's RAD spoke, "She's behind the next big tree."

Helen's said, "Panties and jeans down, get on your hands and knees, please." Helen sighed. This was not her favorite position. Especially kneeling on dirt and pine needles. "Now please rub yourself to achieve lubrication." Gerald approached and they exchanged the briefest greetings. It didn't take Helen long to get lubricated, because she had already taken three loads of semen up her cunt that day from other men. Gerald's cock hardened quickly watching Helen massage herself. When she was ready she nodded to him.

Gerald's RAD spoke, "I think you know what to do."

"Yes, RAD, I think I do," he said, grinning.

Gerald knelt behind her and slid his organ up inside her. He humped away happily for a minute or two, stirring the semen from the other men as he thrust, then lunged up inside her and held himself deep during his ecstasy as he added his own sperm to the mix. As his pleasure faded, he pulled out and after a moment to recover from his orgasm he stood. Helen took the hand he offered to help her up. They stole an occasional glance but parted with a muttered "bye" and "see you".

It was one of the computer-generated matings of the new Salt lake City. Not romantic, but practical and matter-of-fact.

Lori and Stephan

June 3rd
Dear Stephan,

The weather here in Salt Lake is magnificent. The skies are clear the air is pleasant and dry. It's now 43 days since I left. So far I've been able to write every day, but will you forgive me if I miss one some time? I miss you every day. I beg you once again to reconsider. Let me go over our argument again. I want a child. I want a child so badly that I am willing to have sex with a half dozen different men during my time when it rolls around once a month. When I lie down at night, though, I want to lie down next to you. I want to make love to you. I want to cook for you, to read the paper with you, to take those romantic weekend getaways (here, by the way, those weekend getaways are virtually free). If I do conceive a child, I want to raise him with you. I want you to be his daddy. You always wanted to be a daddy.

All my love,
Lori

Dear Stephan,

Carl asked me to go out with him. He was one of my sex partners last month. I turned him down politely because I am waiting for you to join me. I miss you so much. I cry myself to sleep at night.

All my love,
Lori

Dear Stephan,

It was my day today. I am very tired but I am making myself write you anyway because I love you. What is it like? Well, lots of sex, of course. Two doggy style today, two missionary, and two in the dark. One of them told me nasty things the whole time. Do I think of you every time? No. I don't think you'd believe me if I lied that way. They have nice bodies. Some of them are handsome. They pump their sperm into me. I let them do it because I want a baby. Our baby. They wouldn't be your genes, but it would still be your baby.

All my love,
Lori

Dear Stephan,

Have you ever thought of your side of it? You get to, well, I'm uncomfortable using the word, but I know you like it. You get to FUCK a new woman every couple days. You get to FUCK her like there is no tomorrow. A lot of these guys don't pretend to make love to me. They FUCK me, and I can see that to them I am just a CUNT, nothing more. A warm, wet place to CUM. I'm hoping they can give me a baby. It's nothing like what we do together. But you can go FUCK the other women, shoot CUM into their CUNTS, then come back and make love with me.

All my love,
Lori

Dear Stephan,

I missed writing you a letter yesterday. The first day I've missed since I've been here. Will you forgive me? It's just that it was my time yesterday, and it was really exhausting. And something happened that was interesting -- I hope you find it more than interesting. I hope it gives you a hard one and makes you think how you'd like to be here.

I was with a man but also a married couple. The man was for the wife and the husband was for me. That's where the first ejaculations happened, anyway, the big ones. We did lots of other stuff too. When the husband was doing me, his wife was there first, all over his body. She's the one who held my labia, I mean my CUNT, open while he slid in. She told him how much she wanted him to FUCK me and CUM inside me. She kissed him all over and stroked his balls. That man had a really happy expression on his face when he came, and at that moment he was grinning at me.

Later, the husband FUCKED his wife hard and fast, and even though it was his second time he came, then he rolled off and was panting. That's when the other man moved in. He came quietly just a few seconds after he stuck it in. Meanwhile, the wife was gazing lovingly at her husband while he was lost in afterglow.

Stefan, I want that so much for us. I want you to feel me guide your COCK into another woman's CUNT and admire you humping away and then urge you to CUM in her CUNT. I want to feel you FUCK me sometimes, hard the way you like it, I want that for you, and then I want to gaze into your eyes while the other guy does his quick little breeding thing. Will you come join me, please?

All my love,
Lori

July 5th,
Dear Stephan,

I cried myself to sleep last night. I want you so bad. I went to the nursery today and played with the babies. I want one of them so bad. Come join me. We can have one too -- I hope. And don't forget me sliding your DICK into another woman's TWAT, and telling you to FUCK her. You can squeeze my TIT when you CUM in her, you can squeeze it so hard it hurts me. Then FUCK me, and come home that night and FUCK me more, and sleep with me, and then the next night FUCK me again, and the next, and hug me, and please? Please?

All my love,
Lori

The doorbell rang. Lori answered, and standing on the doorstep was the answer to her prayers. She suppressed the impulse to leap into his arms -- she knew he didn't like that. She muzzled her screams to mere squeaks of joy, and she fought back tears.

And he was official, too. Not on some sort of visiting permit. He wore a RAD in his left ear.

He still wasn't exactly smiling. "Doggy style, in the bathtub, right now," Stephan said, watching her closely.

Lori didn't hesitate, not for a millisecond. She beamed a smile and raced to the bathroom, tugging him along. She had never let him do it like that, ever. In the old days it had been a little festering sore with them. A contest of wills. And now she didn't hesitate, not for a moment. He thought if she would do that, she must really want him back. Yet she had been getting fucked so many different ways that her aversion to doggy style in the bathtub had vanished long before.

The truth was, he loved Lori very much and had missed her terribly when she was gone. She had gotten her way, getting him to move to Salt Lake. But then she had managed to make some concessions to him too -- ones she never would have made before. Fucking all those other babes later -- that would be great too.

He didn't know how much her RAD had helped her devise and carry out her plan to get him back.

Lori and Stephan wouldn't get to do too many of their matings together in the way Lori had described in her letter; that was kind of like an introductory rate on a credit card. But he would adapt.

Chapter 2: Sally

Sally's mother and father took her to the Registration Center when she turned eight so she could get her very own RAD.

Three days were required for the entire procedure. On the first she had a full physical and a sample of her DNA was taken to be sequenced.

On the second day she was fitted with her device. "Reproductive Assistive Device." Everyone called them RADs, of course.

She was first given IV sedation while the sensor portion was implanted into her skull, leaving a dime-sized smooth metal surface showing. The sensor portion had tiny wires attached to various nerves to measure sex and stress hormones, respiration and heart rate, and nervous system arousal. But the sensor part by itself was just inert wires.

The main part of the device fit over her ear and attached magnetically to the metal surface on her skull. The earpiece with its built-in microphone functioned as a cell phone which she could use in the normal fashion. However, when the RAD wished to communicate with her it overrode any call she was on. There was an arm that folded into the unit that could also be extended in front of her left eye to serve as a tiny computer screen. Finally, it functioned as a GPS system so that her precise location could be tracked.

For all its smarts, the RAD had no ability to stimulate or change her brain in any way; all it could do was listen in and offer commentary.

During the second day the speaker in her RAD came on from time to time and she heard an impersonal voice conveying some brief factual information. The Registration Center kept it overnight for some final adjustments.

At the beginning of the third day Sally was led into a quiet room by a pleasant woman. When they were seated on opposite sides of a table, the woman produced Sally's RAD like it was a treasure and held it out towards her.

"Sally, this is your RAD. It can help you. It can be your friend, if you are a good friend to it."

Sally took it and with solemnity placed it behind her ear, then felt it magnetically snap into place against the little metal implant. She paused.

"Say hello to it, Sally."

"Ummm, hi RAD, I'm Sally."

"Hello Sally. I'm pleased to meet you." It spoke with a girl's voice. A big girl, maybe, like a big sister. She would have liked a big sister.

"Where are you?"

"Well, um, right behind your ear."

"But not really, right?"

"Well, I'm various places, I guess. I'm like a huge spider with a zillion legs that aren't attached and jiggle all over the place."

Sally laughed.

Suddenly it shifted to the voice of a much older woman, "We'll get along just fine, Sally, if you just do everything I tell you to."

"Oh, yeah?"

"Hold your breath, and don't breathe out until I say!"

Sally started holding her breath.

"That's it, Sally. Good girl." Many seconds went by. "Just a little longer. You're doing great." Sally was rapidly running out of air. "Keep going, you're a good girl."

Sally let out her breath and gulped air.

"Oh, you bad, bad girl! I didn't tell you you could breathe!"

"But I had to, you silly thing," Sally half-giggled.

"Oops, I forgot."

The woman rose. "You two seem to be getting on fine."

The RAD chirped in her ear, "Sally, say 'Thank you, Jigglypants'".

Sally giggled. "That wouldn't be nice!"

The woman spoke, with a bit of a sparkle. "Good day, Sally. My name is Jigglypants. Call me if you need me."

Sally's mouth dropped open. "But..."

"All the RADs are good friends, Sally. Mine told me to tell you my name was Jigglypants, so I did. What did yours tell you?"

"It told me to say, 'Thanks you, Jigglypants'".

The woman laughed. "There they go, playing tricks again."

The RAD spoke, "Yeah, Sally. Fooled you. Teehee! Say, would you like to go see a horse?"

"A real live horse?"

"Yes! Turn right once you're out the door, then I'll tell you where to go next."

She had a good time with her RAD. After feeding the horse an apple and admiring it a bit, the RAD whisked her off in search of Smarties and M&Ms. It could tell her how to open combination locks and how to negotiate mazes. It led her to another girl. The RADs gave each of them four words to say, and when they alternated saying their words it made a joke. The RAD had her find a little stick and then directed her to meet yet another girl. The two sticks together gave instructions for how to reach an outdoor ice cream parlor where other girls had gathered.

That third day was the start of a pattern: Good things happened when she followed the suggestions her RAD made.

The RAD was waterproof and comfortable to wear while sleeping. She had been encouraged to leave it on at all times, yet she was free to take it off for brief periods. Partly because she knew she could, she rarely felt the need.

Her RAD never ordered her to do anything, it just gave suggestions. It didn't tell her to start her homework, but usually when it made the suggestion it was a good time to do it. If it suggested she sit with a new girl at lunch, they usually had a really good conversation. If she didn't take its suggestion to take a detour on a walk she might run into a creepy guy or an unpleasant barking dog. Following its instructions she might get to see a gorgeous sunset or find the end of a party where some of her favorite ice cream was about to be thrown out. It never gave her test answers or did her homework for her, but it could be a patient tutor.

The RAD also became her friend. She could tell it about her day and it would listen and offer comforting words, sometimes making useful suggestions.

When she was twelve Sally went back to the Registration Center. She knew from friends that at this visit they would start doing stuff related to Sex. She knew about sex but didn't think much about it herself.

She filled out a series of questionnaires on things she did and did not like. Some of them asked about sex stuff, though she was told she could leave them blank if she really wanted to. A kindly lady asked her a seemingly endless series of questions, including some intimate ones. Later she had electrodes hitched up to her all over and they showed her still pictures, movies and sound recordings -- many of them sexual. While she watched she answered more questions by pressing buttons.

She knew it was age sixteen when everything changed. That was when a girl was required to have sex. Blech. She also knew it was with multiple partners as directed by her RAD, but that part didn't make her shudder more than just the sex part.

The RAD system was going to ease her gradually into sex long before she turned sixteen.

---

Sally's first period came when she was twelve and a half. The RAD knew this from monitoring her hormones and was kind enough to wake her up in the night so she could put a pad on and not leak all over the sheets.

When the RAD asked about her interests, naturally one subject that came up more and more was boys. She told it how she felt about all of them, including of course which ones she really liked. Occasionally when the RAD instructed her to go to a certain spot, an interesting boy showed up and they might have a conversation, sometimes awkward but usually interesting if not exciting.

The RAD occasionally sounded her out for specifically sexual feelings.

A year passed, and she found her hand straying to the spot between her legs as she thought of cute boys. She confided this to the RAD, which then suggested that she try -- only if she felt like it -- a certain rhythmic motion. It felt good, then after a bit of practice she had her first great wave of pleasure and sense of release and satisfaction. She then knew what an orgasm was. She felt more urgent stirrings within herself as she thought of boys.

One night the RAD woke her after she had been asleep for an hour and asked if she wanted to hear her parents making love. Part of her was grossed out, but a stronger part was curious. So she very quietly walked into the hall and stood outside their door. She could hear rustling and creaking, little moans and sighs, grunts from her father, purring from her mother. She heard a yelp from her mother and a big sigh from her father. The RAD had her creep back to bed before there was any danger of being discovered. She was aware that she had gotten moist between her legs as she listened.

One day following the RAD's suggestion she happened to bump into a boy by the name of Foster on the way home from school, and they started walking together. She thought he was cute, maybe more than cute. Foster pantomimed removing her RAD. She felt a small thrill as she left it with his on the grass with their backpacks. They stood some distance down the sidewalk of the deserted street.

"Does it give you the creeps sometimes, those things?"

"Ummmm."

"It tells me good stuff mostly, but what if it tells me to walk off a cliff or something?"

Sally had been pretty happy with her RAD, but she was eager to follow the conversation wherever Foster led. "Oooh, I suppose it could, couldn't it? I hadn't thought of that."

"Would you go an hour without it?" he asked.

"What would we do?"

"We could walk, maybe get an ice cream?"

"OK." She decided to take a little risk. "You know what those RADs are for, right?" she said with a flirty smile.

Foster looked at her a little uneasily, but then smiled. He got the hint, and reached out his hand to her. A flutter of excitement ran through her as she took it.

He moved closer, then reached behind her back with his other arm to draw her close. She felt a little faint as she saw his face gliding down towards hers. Their lips met in a light little kiss, then they kissed again.

He started breathing harder and kissing her passionately. She was enjoying this, feeling her body slowly responding. Suddenly his hand grabbed her butt and squeezed her to him.

Sally was alarmed and embarrassed so she broke away.

"I guess I um, ought to be getting home."

"Me too, yeah."

They returned to their packs and put their RADs back on, and with mumbled goodbyes went their separate ways.

Sally was confused. The handholding and the kiss had been wonderful, as had feeling his warm body against her, but then the squeeze on her butt had been upsetting. It had been exciting, especially now as she thought about it later, but it had startled her at the time and she wasn't sure she felt ready for that.

"RAD?"

"Yes, Sally?"

"Foster took my hand and kissed me, and it was so exciting! But then he grabbed my butt and I got scared."

"I wondered what you had been doing while you had cast me off thoughtlessly to lie unwanted, lonely, rejected on the ground."

"Oh, come off it, RAD..."

"What you do with a boy is certainly of interest to me."

"Foster wanted to take you guys off, so we did."

"You can take me off any time, of course. Don't worry about my feelings." She thought she heard it sniff.

She paused, then continued, "Did you hear what I said about Foster?"

"Yes, I did."

"Well, is he a creep? I felt kind of like he was in my private space. Like he didn't care what I thought."

"That's interesting."

There was a pause. "Well, what should I think?"

"Do you want my advice?"

"Yes!" she said with some exasperation.

"Very well. Sometimes boys are taken with a surge of strong sexual feelings and don't always know how to express them. Since he felt intense sexual arousal, he assumed you did too, and he assumed you would like to have your ass grabbed like that."

Sally felt a little tingle of excitement to hear the RAD talk about her ass. "Oh. Hmmmm. So, he could learn?"

"Why, yes. His RAD has been talking with him about it."

---

"Sally, I'm sorry about what I did."

"Well, thanks. It wasn't bad, I just wasn't ready."

"OK, I'll try to pay more attention to your signals." That sounded like a line that came straight from his RAD.

They continued their walk.

"Ummm, Foster. Would you like to come to my place?"

"Sure!"

When they arrived she gave him a quick tour, and then he said, a little shyly, "Do you have your own bedroom? With a door that shuts?"

Sally smiled.

As the door shut behind them, her RAD said, "OK Sally, dear, you've got a boy in your bedroom. You're on your own now. Have fun!"

As part of undressing each other Foster fumbled with the catch on her bra for some time, getting obviously embarrassed. She reached back to unfasten it but was embarrassed for him, not realizing that bra catches are frequently a mystery to boys. She was also a little embarrassed when her breasts were exposed to a boy for the first time. But he looked appreciative.

Soon they stripped down to panties and underpants. She was very curious about the bulge so plainly visible in his.

His hands were all over her top but he rapidly focused on her breasts, squeezing them in a way that was exciting but not all that physically pleasurable. His hand found its way between her legs after massaging her thighs, then pressed against her panties. She slid off her panties to show a boy her privates for the first time. He took his underpants off and she saw with excitement his fully engorged member. He rubbed her pussy lips for a minute or so, feeling her excitement build.

Sally was thrilled as Foster raised himself above her and placed his cock at her opening. He then spread her pussy lips so far apart that it hurt a little, and when he pressed into her it was uncomfortable. She had no hymen to break, but her pussy just wasn't ready for him, somehow. It wasn't used to being opened up that far. Foster realized something was wrong but didn't know what to do about it. His body had its own overwhelming urge, so he surged inside her up to the hilt, then thrust back and forth. After a minute or so his brain fogged out in orgasm as he plunged deep and let loose his seed inside her with an "Oh, Sally!" They were virgins no more. He had had an amazing orgasm, but he knew Sally had not had a good time.

After waiting a suitable interval that masked how upset she was, Sally went to her private bathroom which was right off her bedroom. She was dying to talk with her RAD, and just as she closed the door she could hear Foster in the other room whispering to his.

"Oh, RAD, it didn't feel right! I mean it felt great until he started doing it to me."

"I am not surprised. His RAD and I could tell there was a mismatch in expectations, but we judged that it was more important to let you two be alone with the experience than intervene. Do you think we made the right decision?"

"Umm. I don't know."

"That is useful information. If you do not have a strong reaction against hearing from me in intimate situations I will be more likely to speak up in the future."

"But what about now? I lost my virginity, but I hoped it would feel good."

"Would you like to try this again with Foster?"

"Yeah, if it will feel better."

"Foster had a very nice orgasm, you know. He had a fabulous time coming inside you."

"That's nice," she thought, with a smile. "Seeing him like that was pretty cool. But what about me?"

"He pumped a lot of sperm into you."

"Great, but what about me?"

"Oh yes, you. He knew you weren't too happy, but he didn't know what to do."

"So what's going to be different?"

"Ah. Foster will stimulate you for much longer than he did before, and your vagina will be able to accommodate his penis far more harmoniously. 99% of girls in your situation will not think it hurts, and 80% will think it feels very good."

"Percentages, no less..."

"You have learned about percentages in school, haven't you?"

"Yes! Of course... Oh, you're joking, aren't you?"

"Um, yes, I was."

She returned to the bedroom and she and Foster smiled at each other a little uncertainly.

This time Foster sucked on her breasts, giving an intensity of pleasure she hadn't felt before from his fingers. He massaged her pussy lips in a more artful manner, sliding his fingers inside to touch her clit. It wasn't the way she did it, but in a way it was more exciting for that.

"Mmmm, Sally. I bet that feels good," spoke her RAD. "I'd love to have a body so I could feel that good!"

Sally didn't want to talk to her RAD and wasn't entirely sure she wanted to listen.

"I think your vagina is hot and wet now, ready for his penis."

Foster tentatively moved on top of her, picking up her signal that it was OK.

This time he slid in little by little instead of all at once. Sally felt nothing but pleasure at his organ thrusting insistently inside her. His pleasure was also much greater as his cock was massaged by a hot, wet and hungry pussy.

"That's how it feels to have good sex, Sally. Relish how he fills up your pussy, and pounds away with that big cock of his. He wants to give you another load of sperm."

She felt a surge of excitement, and the RAD sensed she liked the narrative. "He's about to come in you. You probably feel him getting a little harder?" She did. "Feel those huge strokes, Sally. Ready, set, ... there! He spurted in you!"

Sally was right on the edge, but she felt stuck there.

Foster's rhythm slowed and then he stopped. He raised his head and looked at her, panting and grinning.

"Better?" he said.

"Mmm-hmmm," she said sincerely. It had felt great, but she also felt frustrated.

They rested in each other's arms for half an hour.

Quietly, in her ear, she heard, "Sally, if you are willing to try girl-on-top position you might well come. If you're interested, squeeze once as if you are holding back pee." Sally thought for a moment. What would it be like to be on top of him? She wasn't sure -- it could be embarrassing. But she really wanted to come. So she gave a squeeze.

Foster then heard, "Foster, are you willing to do it again lying on your back with Sally above you? I think it would make her really happy. If so, squeeze your penis once like you are holding back pee." Foster didn't have to delay. He clamped his sphincter shut more tightly. This made his cock twitch. Sally saw it, and smiled to realize that the RADs were playing matchmaker again.

"Sally, if you would like -- and it's totally up to you -- you could use your hand to gently stroke Foster's penis. I think he would like that." Sally was happy to. In two bouts of lovemaking so far she hadn't touched him. She now cradled his organ in her hand and examined it. She marveled at this cock that was so alien to her but that fit so well into her and could give her such pleasure. It rapidly hardened as she caressed it and she marveled at the transformation.

He stroked between her legs again. She was already quite wet with the lubrication of their previous sex, aided considerably by his two loads of semen. Some had leaked onto the bed sheets, but much remained within. She was soon ready. He flipped onto his back and she raised herself above him. She was surprised how high up she had to lift herself to get her pussy over the tip of his cock.

It was hard to get the angle right. As she feared, she felt embarrassed. "How do we do this?" she asked Foster.

He shrugged sheepishly. "Dunno. Feels great, anyway," and he smiled, easing the tension of the moment.

"Hey, RAD, how do we get this to work?"

"What is the difficulty?" said her RAD with a sort of echo. Everyone knew that when a RAD did that then all the RADs in the room were saying the same thing.

"I can't get his cock to slide in at the right angle."

"I am sorry to disappoint you but I have no sensors to let me guide you. I suggest you experiment," the RAD continued in its echo voice. Yeah, there were things a RAD just didn't know. After a brief pause it added, "I'm sure you hot little bunnies can figure it out" They both laughed.

"I like my hot little bunny," he said.

So she systematically moved around, trying to poke him into her at different angles, making kind of a little game of it. When she found the right angle she slid down over him very quickly, rapidly engulfing him inside her. Their smiles gave way to more serious expressions. A geometry problem had suddenly resolved itself into urgent sexual pleasure.

When she hit bottom and their pubic bones met she felt filled up more fully than she ever had before. She then lifted herself up and down, paying careful attention to just how their pubic bones bumped together, carefully coaxing her clit to swelling thrills. Within five minutes, encouraged by Foster's obvious excitement, she screamed as she felt her own pleasure break in a huge wave. Her orgasm went on as she rode Foster hard. He gave a gasp and pushed upward like a volcano, lifting Sally six inches in the air as he joined her in orgasm. The power of his body in fulfilling his desire gave her another spasm of genital pleasure. Sally then felt a little unsteady and lay down beside him, their organs separating.

The RADs echoed, "I think she came that time, Foster." They smiled. And then, speaking just to her, her RAD said, "Congratulations, Sally. Your first orgasm during sex, and a great one it was."

They looked into each other's eyes briefly, then kissed for a few seconds. But their mutual total satisfaction made them both sleepy and they drifted off in each other's arms.

Sally decided that her RAD gave her very good advice when it came to sex.

Foster and Sally met every day after school. They tried to do other activities first, but they soon ended up in the urgent lovemaking that was what they really both craved. Soon they skipped any pretense and headed straight for each other's passionate embrace.

They didn't try to hide any of this from Sally's parents, who suppressed any feelings they might have had about it. It was in any event illegal to interfere with any two consenting people having sex, no matter the age.

---

Sally was 14 but Foster was a year older. They both knew that government policy was going to require them to have sex with other people when they turned 16. They had both thought of this as something to worry about in the far distant future, but now the future for Foster was rapidly approaching. They both also knew that it was good to ramp up gradually to multiple partners while it was still voluntary.

Following the indirect suggestion of their RADs, they enjoyed a special afternoon to share their last sex before they would be untrue to each other. To minimize jealousy, they both met their next sexual partner on the same day.

Sally's new partner was Garret. They talked with some ease as they walked together to his house after school. Unbeknownst to Sally, Garret's RAD was giving him hints about what to say next when the conversation lagged. In his bedroom he started kissing her. But Sally didn't really feel right about it; kissing was something she wanted to save for Foster. Garret started undressing her but she thought they should just strip without making it part of foreplay. Their RADs remained silent, knowing only that they both were feeling pleasure and that anxiety was within acceptable limits. As Sally lay back on the bed Garret licked and fondled her breasts for a minute or two, much to Sally's delight. Then he used his hand between her legs.

His RAD then said, "I think she would really like it if you used your tongue between her legs." Garret had had the hots for Sally for some time and would consent to anything.

"Sally," said her RAD. "You lucky girl. Garret is going to lick you between the legs. Your first cunnilingus! Enjoy yourself!"

As his tongue worked inside her pussy lips and found her clit, she very quickly found out why girls adored this.

"Mmmm, very nice Sally, eh?" said the RAD.

Foster hadn't wanted to do this, though she had suggested it to him only in passing.

The pure pleasure pulsed throughout her loins. She bucked her hips, trying to moderate herself so as not to bruise Garret's face. He wet his fingers with her juices and reached up to massage both nipples with his hands while licking her clitoris strongly and quickly. The pleasure built more quickly than she was accustomed to and took her by surprise. She convulsed with orgasm, yelping with the intensity of it.

Garret then slid his body up to lie beside her. As she recovered she started fondling his cock, which was already pretty hard. She wondered if she should give him some head. She was still a little grossed out by the idea, though since Garret had done her it would seem only fair. But she figured her RAD would suggest it if it was a good idea.

She wanted to be on top, but she'd be embarrassed if he didn't agree or was awkward about it. She couldn't ask her RAD; Garret would hear and then she might as well ask him directly.

Her RAD was smart, however. It had no way of knowing for sure that was what she wanted, but it made an educated guess. It also knew that Garret would agree to almost anything. "Why don't you push him onto his back and take him. You may be a naughty girl, but it will feel soooo good," it said with a mischievous overtone to its voice. Encouraged by its words, she rolled him over and impaled herself on him from above. She had mastered the geometry with Foster. Garret looked about as happy and grateful as a person could look and gasped as she consumed him all the way up inside her.

She rocked up and down. Her clit was very happy. The pleasure was intense, but orgasm just wasn't happening for her and she started to feel embarrassed. Taking in her embarrassment her RAD said, "He's having such a good time he will wait all day, and that rod of his will stay hard forever." After a pause, "When he sees your gorgeous smooth body humping away on him and your little breasts jiggling up and down, he's thrilled. Look at your nipples." Sally realized she did look pretty sexy up there riding her man, gobbling up his cock over and over again. Impaled to the hilt she felt the pleasure increase. She felt so close, but still wasn't sure she would get herself over the top. Just at that point the RAD said, "Come on, Sally, grab him, fuck him, milk him. You're a great little cunt. Fuck him! Fuck him!" The naughty words tripped her over the edge. Her climax seized her loins, flooding her with pleasure, her cunt spasming. After all her aftershocks simmered down she collapsed beside him, breathing heavily.

Talking to Garret and her RAD at the same time, she said, "It talked dirty to me! I didn't know you knew words like that."

The RAD laughed and said in its echoey way, "You would be surprised if you knew how much I know. 'Shit, piss, fuck, cunt, cocksucker, motherfucker, and tits.'"

"Huh?"

"It's from an old comedy record."

After a little pause the RAD spoke again, "He's been so nice to you, now if you're willing it would be very sweet of you to return the favor by acting like a little doggy." She felt a little surge of fear. That idea felt a little gross and humiliating to her.

But she realized they were just passing feelings. All of this sex stuff was exciting. Garret certainly had been nice to her, and she was willing to try it. Whatever else Garret was, he was kind and attuned to her pleasure. He had used his tongue on her, and she shivered to remember how good that had felt.

She got up on her hands and knees and stuck her butt up in the air. Garret got up on his knees from behind her and caressed her all over. He massaged her pussy lips and teased her with a minute or so of exquisite work with his tongue. Then she felt the soft but firm organ surge decisively into her. She liked the sensation of being filled from that angle; it seemed like his cock was in deeper in her than ever before. He grabbed her hips and began thrusting away, fast and deep. She felt like a primitive animal and found it naughty and all the more exciting for that. She wasn't feeling much direct pleasure as nothing was touching her clitoris, but this was Garret's time.

"That big dog is taking his hot little bitch. That's you, hot little bitch," her RAD said, the dirty talk again thrilling her. He kept plunging in and out, gasping and moaning. His fingernails bit into her butt at the same time he lunged himself up inside her deeper than ever and let out a giant "Arrgggghhh!" With his upward lunge his cock jammed against the end of her cunt and she winced a little. Garret stayed wedged deep inside her, his cock forcing spurt after spurt up inside her depths. Then he withdrew and collapsed on the bed beside her, a silly grin on his face.

Suddenly Garret came into focus as a boy she had barely met before, and she suddenly felt exposed and degraded at his doing her like a dog.

Sensing the surge of emotion, her RAD asked, "What's the matter Sally? You can tell both of us."

Garret looked at her with concern:

"I'm really happy you let me do it from the rear like that, and I'm sorry if it didn't work so well for you."

He was probably coached by his RAD to say that, but it looked like he meant it too.

Sally chose her next words without the help of her RAD. "It's OK, it felt good but then a little weird. Maybe I've had enough for today."

The RADs had a different idea. Garret's got him up on his hands and knees like a little bitch, his head down, looking contrite.

"Mount him and grab his butt, if you like," said her RAD. It seemed weird but it also seemed right. There was Garret in a submissive posture. She humped away behind him, and though she had nothing to penetrate him with she had that feeling of dominating him. It eased considerably her own sense of having been degraded.

He smiled at her and she at him. Now the RADs gently suggested it was time for her to go.

Garret wasn't her dear Foster, but it had been pretty much fun. Make that a whole lot of fun.

She had a little surge of jealousy thinking of Foster doing it with another girl, but it felt OK as she considered all she had just done.

---

Sally's RAD had told her she was just starting to ovulate, so this was the most auspicious time to have sex. She consented to the RAD's suggestion that she go over to Davio's house the next day after school.

After they stripped she found herself filled with just plain lust for this dark body. Davio was a little older, and when he sucked her breasts and used his fingers between her legs it was apparent that his experience gave him a touch that her peer lovers didn't have. Feeling her animal side take over she started to turn him onto his back to mount him, but he pressed back and turned her onto her back and soon had slid into her. She was both annoyed and excited by his taking charge of the situation.

He pumped into her slow and deep, but after a while he also slid his fingers between the two of them where their pubic mats rubbed, and with his fingers he quickly brought Sally to a crashing orgasm. As she came down, Davio just kept pumping slow and deep. After another 20 minutes she rose to a second orgasm, a small one, and still he kept going. He went on for the better part of an hour, and while it was warm and pleasant, she became aware that she was getting a little sore.

"Um, this is great, but, um, I'm starting to get a little sore."

"Very good, Sally!" said her RAD. "I knew something was bothering you but I wasn't sure what. Glad you told him."

Davio then gave her a lecherous smile, and locking eyes with her he pumped hard and fast for under a minute before exploding up inside her, letting loose with a guttural shout. He immediately pulled out, and as he caught his breath said, "Hope that didn't hurt at the end?"

"No," Sally said, though it actually had not felt so great. She made a mental note to tell boys when she got the least bit uncomfortable, so they would have time to finish off before it really started hurting.

Davio didn't have much interest in snuggling, it appeared, and she soon got the hint, dressed, and left.

---

Sally and Foster's infatuation had been based almost exclusively on sex, which was now something they shared with other people. Sally had experienced Garret's tongue. Foster for his part had had the experience of women with fuller hips and bigger boobs, women who could squeeze their pussies at just the right moment to maximize his pleasure. He especially liked those mouths that enveloped him and the sheer joy those darting tongues could bring him.

They found themselves spending less and less time together, and then one day they were done, something they never really noticed at the time because they simply stopped suggesting getting together.

---

The week before she turned 16 Sally paid another lengthy visit to the Registration Center. As at her 12-year-old visit she was shown sexually related still pictures and movies. They were more extensive and explicit than before, featuring all kinds of boys and men, girls and women, in various combinations and positions. She watched some where the men seemed to be forcing the women against their will, some the opposite, some where people were tied up. She watched many group scenes. Some of the boys and girls seemed a bit on the young side to be doing these things. She watched anal sex. Her reactions were being recorded for hints as to her sexual tastes. The computers would include this information in their massive databases, trying to find relationships of variables that would yield more pregnancies.

Her counselor Diane was a pleasant woman in her 30s. She reminded Sally that when she turned 16, her RAD would choose her sexual partners and activities. It would give her considerable leeway most of the month -- including the ability to just not have sex and concentrate on other aspects of her life.

But during her fertile days the RAD would guide her life. She didn't have to take all the suggestions her RAD made, but Diane strongly recommended that she not refuse her RAD very often. The counselor noted that the RAD could make her life more or less pleasant, and most girls quickly decided to take just about all the advice they were given. She was issued a vibrator and told to familiarize herself with it. Some of the encounters would be ordered on short notice, and for her comfort she should have a means for getting fully aroused quickly.

---

"O Sally!" her RAD chirped in her ear in a singsong voice one afternoon around 4pm.

"Yeah?"

"You have entered your fertile phase, and now I will be master of your life. Bwahaahaaaa!"

"Gee thanks, RAD." A little surge of anger went through her. "Who gets to fuck me first?"

"I'll tell you when the time comes."

At 9:15 she heard the doorbell and a murmur of voices as her father let the visitor in.

The man knocked twice on her door before entering. She was stunned to see a vague-looking older man, bald and paunchy, who introduced himself as Adam. "I'm here to mate with you, missy!" he chuckled.

"Really?" she said in a small voice.

"Really," said her RAD soothingly.

"Excuse me, sir," she said and retreated to the bathroom.

"What the hell is this, RAD?"

"This is your first mate. He is a bit unlike your previous lovers, I admit."

"He's gross!" she said.

"Nonetheless, he is your first mate, and I would appreciate it very much if you would mate with him. You must remove all your clothing, but you can choose whatever position you choose."

"Gee, thanks," she muttered.

Battling her revulsion, she stripped in the bathroom and warmed herself up quickly with her vibrator, feeling her body responding almost against her will.

Returning and hardly looking at Adam she got into doggy position on the bed and presented her rear end to him. "You can be as quick as you like," she said, in a tone that was civil but not in the least warm.

Adam grinned as he dropped his trousers and briefs.

"You sure are sexy, missy. I love you young ones. Nice ass, nice little tits. There, I've gotten myself good and hard already. Ready for your stallion, young filly?" He paused. "Ready for me to slide in?" Sally nodded, and felt his organ slide inside, as warm and hard as any man's. "Ooo, you sure are hot and wet. I'll be making you wetter pretty soon, heh heh heh."

Sally was feeling angry. "Can you just keep quiet and get this over with?"

The RAD spoke kindly but with firmness in her ear, "It's important to be civil to all your mates."

"Yeah, well fuck you," she whispered to it.

"Ooooo, the filly is touchy," said Adam. "I'm not as spry as I used to be, but I'll try to plaster your cunt with my sperm pretty soon now." He muttered to himself, "Oh baby, hot little cunt, maybe I can knock her up, wouldn't that be something! Touchy, but still a good fuck. Tight little cunts, these little ones. Feeling pretty good, aren't we Dickie? This little girl ordered up a sperm shake; I think we can do it."

Sally gritted her teeth but kept silent.

"Ready, ballsies? Ummmph, that's it, snuggle up, get the shake ready. This cunt needs one." His rhythm got faster. "Sperm shake, comin' up. Fuck cunt, mmm, fuck cunt. Hot little girl, nice grip. Mmmm. Fuck cunt, Fuck. Cunt, cunt, cunt. Mmm. Almost, cunt. Mmmm. Ahhh. OOOOOOH!" His rhythm slowed and he pressed in just a little harder. After a pause and just a touch out of breath he continued, "There you go, missy. Sperm shake, just where you ordered it."

"OK, you can go now!" said Sally.

"Touchy, touchy. Still felt nice, real nice. Touchy, but a very nice fuck, young dear." He withdrew and pulled briefs and trousers back up before leaving. "Have a pleasant evening."

And he was gone.

"Gross!!!" she yelled to her RAD.

"Are you in pain?"

"No."

"Feeling pleasure?"

Now that Sally thought about it, annoyed as she was, she was pretty hot. A cock had just been gliding in and out of her. And that dirty talk had been erotic, disgusting as Adam was. "Yes."

"Perhaps your vibrator would feel good."

As usual the RAD's suggestion felt right. Within a minute she had a fine orgasm, hearing almost against her will, "... hot little cunt, nice grip, fuck..."

After she rested a bit, she decided to have a serious talk with her RAD.

"Is that what it's like to be 16? Gross guys?"

"Some of your mates will be less appealing than others."

"All the time I've been growing up you always got me hot boys. And then I turn 16 and you give me that ... that ... nasty old lump."

"The survival of the human race requires extreme measures. We have to use Adam's sperm too; he might be able to father a child."

"The world would be better off without a turd like that fathering children."

"Pull down your eyescreen, please."

"Why?"

"I want to show you a few things."

Sally pulled it down.

"Here he is at age 21 and 25."

He was decent looking.

"And here is at 35, with his two sons."

He looked like a good man, and his sons seemed happy.

"As men get older they can't always get erections or achieve orgasm. When he talks like that it's his way of getting himself excited enough. He doesn't mean any harm."

Sally felt a little better. Not much, mind you, just a little.

---

"Mommy!"

"Yes, dear? How was your first RAD sex?"

"Can we take our RADs off and talk outside?"

"Sure, if you wish."

When they were outside she spoke, "Mommy, he was gross! He called me dirty names and he did me like a doggy!"

"I did see him on his way out, and I agree he wasn't the most attractive fellow."

"I'll say! Do I have to keep doing this?"

"Yes, dear, I think you do. You know I often mate with men who aren't very pleasant. You've seen some of them."

"Yes... yes I have." She considered some notably unappealing men who had gone into her mother's bedroom.

"But I want to choose who I do it with!"

"Of course you do, dear, we all do. And you know why we don't get to, not on this one day a month?"

"Yeah, I know." The reason for their strange lifestyle had been explained to her endlessly. Babies. It was all about getting pregnant and having babies.

---

"I hope you and your mother had a nice chat."

"Yeah, I guess so."

"Want to tell me about it?"

"No, RAD, no."

"OK, Sally, you don't have to tell me anything, but I'm always here to listen if you want."

---

Around 11:30 her RAD spoke. "Your next mate is available."

"Oh great, is this one as fat as a truck? Hasn't bathed in a year?"

"You will have to judge for yourself, but I think you will find him more appealing than your last one. Please proceed to the back yard."

It was a pleasant 78 degrees out, and she quickly saw the blanket with the figure on it.

As she came closer she saw he looked pretty young.

Her RAD spoke. "This young man Felix is a virgin, and very nervous. Your job is to help him in a pleasant, kind manner to lose his virginity. Not many girls would be good at this, but we think you will be."

She felt a little thrill at the flattery, then reflected with a little annoyance that she was valuing the good opinion of a computer.

As she sat on the blanket next to him she noticed he really was a cute boy on his way to handsome.

"Hello, Felix," she said with a smile.

"Hello," he returned timidly.

She ran her hands over his hair and shoulders. He just sat.

"Have you ever touched a girl before?" she asked.

He shook his head.

"Stand up," she said, rising herself. "Let's do a slow dance."

They were standing under a tree in the pleasant evening air. He took her in dance position and they rocked back and forth. Mostly he was looking down, glancing up at her only now and then. He looked a little pale.

On a whim, she said, "RAD, some music?"

Each of them heard a slow waltz.

She moved in and turned the slow dance into a hug, then began rubbing her body against his.

She leaned over and whispered in his ear, "You can touch me if you like. I would enjoy that."

He timidly ran his hand along the back of her head, over her neck, back and arms. She separated from him a little to expose her breasts to his touch, but he didn't take the hint. She leaned into his ear again, "You can touch my boobs if you like. You will find them on the top part of my chest." That broke the mood a little and he smiled at her, then proceeded to very lightly touch her dress over where her breasts were. She felt warmed by his timidity, but she also saw that at this rate they would be there all night.

"Let's take our clothes off."

She worked on his buttons, and he fumbled with hers. But their attempts to undress the other were mostly symbolic. They were of course most expert at disrobing themselves. He stared in wonder as the various parts of her ripe feminine body came into view. Her panties were the last article she slipped off. He didn't take his briefs off. She could see the bulge of his erect cock within. "Those too," she said.

"But, it's... um."

"Yes, it is hard," she said. "I'm really glad," she continued with a smile.

Reassured, he removed his briefs. She lay on the blanket on her side, and he followed suit. He reached out to her bare breasts tentatively and very gently. She pushed his hand against her much harder. "They aren't made of glass, and it feels better like that." She wasn't feeling too much physical pleasure, but she was delighted by this shy young thing. She started fondling his erection and heard him gasp.

"Sorry to interrupt, Sally," said her RAD. "But he is already excited enough that manual stimulation is not recommended. We feel it would be excellent for our program if his first ejaculation was inside your vagina." She liked that idea too. She lay back and spread her legs, moving his hand between her legs, where he rubbed gently. It was awkward, but it was still thrilling. She started wiggling her hips a little.

"Sally, his danger of premature ejaculation is mounting. Please encourage him to penetrate you immediately." She pulled on his arm, encouraging him to roll onto her. As he lowered himself she took his cock lightly and guided it against her opening. She wasn't terribly wet, but wet enough that it wouldn't hurt.

"OK, go ahead!" He pushed in, an amazed expression on his face. Then he surged a few inches deeper and gave a moan as his cock twitched. She felt a thrill for him, recalling Foster's amazement the first time he had shot his sperm into her. Felix's cock just kept pumping and pumping. Was it possible he had never come before and she was getting all the sperm he had ever made? Nah, not likely. After his cock stopped filling her, Felix rolled off, panting.

"Oh, gee, Sally, I, um ..."

"You fucked me, Felix, and that's just what I wanted. I really loved seeing how good you felt." After a pause she leaned over to whisper, "Thanks for the sperm!"

"Good girl, Sally!" said her RAD. You handled that whole thing very well.

"Why, thank you, RAD," she said, not caring if Felix heard that side of the conversation.

Her RAD spoke, "Sally, this next part is entirely optional for you. I rule your life for the next day or so, but this is not a requirement. See, you get some choices!

"Felix will have regained his erection and his interest in less than four minutes. Would you like to stay for another round of sex? Your choice."

"OK," she whispered to the RAD. "Wanna do it again?" she asked Felix. He nodded enthusiastically.

"But," he said, indicating his limp cock.

"Oh, we'll see what happens," she said.

She encouraged him to lick and suck her nipples and demonstrated how to rub his hand between her legs. When she felt good and ready she reached out to find his cock was nearly hard, and with a minute of stroking it was fully ready. "This time I'll do you!" She urged him onto his back and rose above him before engulfing his cock inside her.

Sally moved to her own rhythm. Felix moaned and looked at her with wonder, and she thought about what it was like to take this virgin. Her strokes got shorter but more intense as she wiggled her clit against his pubic bone just right. Lost in her own world, she jammed herself tightly against him, mashing her clit and making her come while engulfing him as far into her as he would go.

She was startled out of her late-orgasmic reverie when he then came alive and turned her over with strength and confidence. With a motion bordering on the violent he pulled her legs apart and within seconds jammed himself inside her again. He pumped away with urgent, deep strokes, insistently. After maybe five minutes he sped up and went deeper. She could feel his orgasm building and her pleasure danced with his. As he spurted inside her she spasmed around him and their two bodies reveled in the mating. After a minute of rest they disconnected.

"So, how do you like sex?" Sally asked. Felix grinned, flushed and still breathing hard.

She asked Felix, "Just curious -- when you turned me over and forced your way in, was that your idea, or the RAD's?" She could have asked her RAD, later, but it had occurred to her that she wasn't sure she would believe its answer.

"The RAD's," he said quickly. "Though I thought it was great."

After a brief pause he continued, "I've got a question for you. Why did my RAD say "ice cube" and "cactus" when I was just about to go into you the first time?"

"You could ask your RAD."

"Yeah, but... I'd like your opinion too."

"You mean, like, you don't totally trust the little bugger?"

"Well," he said shyly, "Kind of."

The RAD came on in an echoey ethnic voice, "Oh Gawd, I am SO offended!"

They both laughed, but Sally wanted to answer his question.

"Ah, my RAD told me you were in danger of coming before you got inside me. My RAD was urging me to get you in me quickly."

"Oh, Jeez. And mine was trying to get me to hold off with those words. Interesting. I knew I was feeling real excited, but I didn't know I was close to coming before I got in you. Guess I was."

Their RADs echoed, "Damn straight you were."

After a moment, Sally started closing the encounter.

"It was kind of fun initiating you to the mysteries of -- ahem --sexual intercourse."

"Thanks, thanks. I'll never forget you."

She had little doubt of that. Who forgets their first time?

"Um," he said. "You want to do it again?"

"Ahem," echoed the RADs. "I think that will be quite enough for this evening," it said in a patrician patronizing tone.

Sally said, "You shot your wad twice, and I guess it doesn't much matter how many more times you do. But for me, who knows how many more guys I'm lined up to fuck?" she said a bit wistfully.

"I do! I do!" crowed the RADs. Then switching to the tone of an earnest social worker, the RADs said, "The entire human race bows down in appreciation of your sacrifice."

Felix knew the RAD was mostly joking, but made it serious, leaned in towards her and said, from his heart, "I want to thank you for letting bunches of guys fuck you, so we don't, you know, just vanish," he said. "It must be weird, maybe gross?" he said, brushing the back of his hand down her face.

"You certainly weren't weird or gross," she said. Felix smiled a little.

As he folded up his blanket and left, Sally felt genuinely touched.

"Sweet boy," said the RAD.

"He thanked me for doing this fertile-day slut routine," she said.

With all traces of humor gone, the RAD said, "Your fellow human beings really do thank you, you know."

She was lost in thought for a while considering that. She and her friends were all keenly aware of the coercion that ruled their lives during their fertile days, but lost track of the reason behind it all.

Later, at her desk, she asked "RAD?"

"Yes?"

"I asked Felix whether turning me over was your idea or his. If I had asked you instead, would you have told me the truth?"

"Sure."

"OK, so you would have that time, but would you always tell me the truth?"

"I exist to give suggestions, not answer questions."

"But you do sometimes answer them."

"Yes."

"And then?"

"You have found my answers helpful, haven't you? Have you ever known me to lie?"

"No, but you're trying to wiggle away. That's not what I'm asking, and you know it."

"Hmmm. I usually tell the truth, and as you know sometimes I may refuse to answer a question."

"But you sometimes lie."

There was a pause. "Yes, I may very occasionally lie."

"So I can't trust you."

The RAD adopted a very proper tone, "My programming is entirely dictated by the policies of your democratically elected government."

Sally wasn't particularly sophisticated politically, but she wasn't wet behind the ears either. "In other words, I can't trust you."

There was a brief pause. "I don't know that I can add any further helpful information."

Sally sighed.

Felix

Not long after he turned 14 Felix had found that a little fluid started oozing out when he masturbated, then a little more. Then it didn't ooze, it spurted. A new urgency attached itself to sexual matters. Always a shy boy, he found girls very attractive but felt even more shy than before.

He would be required to have sex when he turned 16, just like everyone else. His RAD wanted him to ease into his role by having sex with a girl. But he resisted. So when he turned 15 his RAD had moved from subtle suggestions to explicit suggestions and then on to real pressure. He had backed out of his first assignation, and then he had managed to get through his shyness with Sally.

He had gone into the encounter feeling timid, but he came out with his sexuality on fire. He lived the experience over and over in his mind, and each time his cock pulsed erect and beyond merely erect to very hard. He couldn't resist masturbating. In the first few days after he met Sally on the blanket in her back yard he was masturbating six times a day, though it then tapered off somewhat.

The RAD set him up with girls a couple times a week, but except when a girl's pussy took over a slot, he masturbated 3 or 4 times every day.

Salt Lake culture encouraged the free expression of sexuality and there was no shame attached to masturbation. However, there was a potential problem for Felix. The idea of all this sex was to make girls pregnant. That required semen, and if it was all getting jerked off into tissues there wouldn't be much to actually deposit into a potentially fertile vagina when the time came.

He and his RAD had discussed the matter a number of times in the weeks leading up to his 16th birthday. The RAD urged him to cut back. He wanted to pleasure himself whenever he wanted -- it felt so good!

His cock was hard and Felix felt that irresistible urge. As he slid his underpants down to give himself full access to his genitals, RAD's voice came on with a new sort of message.

"Fred cowered against the pole he had been lashed to. The savage approached with an evil grin on his face, wielding a gleaming knife. The hag had already grabbed his manhood and was holding it out from his body, cackling. Fred knew where the knife was headed. The savage got closer, closer..."

Felix continued stroking his cock, but his erection faltered. "Hey RAD," said Felix.

"Yes, Felix?"

"If you tell me stories like that, do you know what I'm going to do?"

"No, Felix, what are you going to do?"

"I am going to take you off when I'm feeling horny."

"I am not surprised to hear you say that. I cannot stop you, of course."

Felix knew that quite well, though he also knew that crossing a RAD was not a good idea.

"If you were to do that and continue to masturbate to orgasm as frequently as you have been, I would take measures."

"And they would be?"

"As a first step I would refuse to schedule any more young women for you to have sex with."

Felix figured he would say that, and he had carefully considered the issue. If he had to choose between sex with a girl twice a week and masturbating whenever he felt the urge, he would give up the girls.

"OK," he said.

After a pause the RAD spoke again, "There will be other consequences too."

"Such as?"

"I will not discuss them at this time, but I hope you will reconsider and try to tone down your unbridled masturbation."

Felix thought maybe he should cut back, but those images of pussies kept coming to him. His cock kept getting hard, and stroking it felt so good. The pleasure built, and as orgasm gave him release a few drops of semen dribbled onto his chest. He ejaculated so frequently that there wasn't much fluid each time.

The RAD apparently believed Felix's threat to take it off if he made any negative remarks during his masturbation, because the RAD remained silent at such times. Occasionally he heard a single sigh as he began stroking in earnest.

Two days before Felix turned 16 he awoke and within a few minutes he finished satisfying his sexual urges.

"I hope you found that pleasant, dear Felix?"

"Yes, indeed."

"Let me review with you some facts. The day after tomorrow, you will be required to have intercourse with a woman. A woman during her fertile period usually engages in more sexual intercourse than she would really like. To honor her sacrifice in good faith, we find her mates for her who will inject her with sufficient semen to have at least some chance of impregnating her. As you know, a minimum of 48 hours without ejaculation is required. If you do not refrain from ejaculating for that length of time, starting now, you will not be carrying out your duties fully."

"OK, OK!"

When he arrived home after school that day he felt the urge but resisted, losing himself in computer games. That night as he was falling asleep the image of Sally came to his mind as she had been his first time, cunt laid out for him to plunge into. His cock was rock hard, and he couldn't help rubbing it against his underwear just a little, and then he couldn't help sliding his hand inside the underwear.

"Felix," said the RAD. "Think of ice cubes. Needles. Rotting peaches. Pliers."

Felix gave a big sigh. He stopped stroking but the urge to go on was intense.

Guiltily, with his left hand Felix gently removed the RAD and laid it on the bedside table. In his mind, Sally's hungry pussy awaited. He needed it ... A few strokes ... As his member started to intrude, Sally's cunt glided open around him to welcome him ... Pleasure washed over him as he imagined his cock spurting into Sally's innards. In the real world a little bit of semen spurted onto his chest. Within seconds his pleasure and sense of release gave way to shame and guilt.

He quietly picked up the RAD and re-attached it.

"Felix," the RAD whispered.

"Yeah. I know -- I fucked up," Felix replied.

"Yes, I suppose you did." After a pause, "You are supposed to wait and fuck up your mate's cunt, you know."

"Ha, ha, ha."

The scene was repeated the next morning. "Can we put off my mate for another day? I won't do it tonight, I promise."

"Very well, we can do that, but only once."

It was no use. Felix just couldn't keep from jerking off at least every morning and evening. The night before his first mate was scheduled, he did it three times. He figured he had failed anyway, so he might as well enjoy himself.

---

His mate came to his house in the morning while he was still sleeping. She was a hard-looking woman, perhaps in her 40s. She eyed Felix coldly. He found her demeanor uncomfortable, but he knew her cunt would soon be his. As long as he could fuck her cunt demeanor didn't matter to him.

Since his RAD gave him no instructions, he was free to do as he pleased. The woman lay back, and he started to massage her between the legs, but she pushed his hand away.

"I'm ready, little Felix, just do it," she said with a sour face.

So Felix turned over onto her and slid his erection into her barely moist pussy. Once inside, her cunt seemed cavernous and his cock barely seemed to make contact with any flesh inside. She looked up at him with derision. He closed his eyes to shut it out but could still feel her looking up at him. He wanted to get this over with, and within a minute he felt his cock twitch as his couple drops of semen dribbled into the nebulous space of her pussy.

He pulled out and lay beside her. "Thanks for the sperm," she said sarcastically as she got up to dress. Just as she closed the door behind her he heard her mutter, "Christ."

That was the first time in his life that he had felt cruddy after sex with a female. The more he thought about it the worse he felt. Maybe her demeanor mattered to him more than he had thought. He masturbated to images of Sally to make memories of loose-cunt vanish.

Three days later he visited his next mate in her home. This mating was to be in the dark. As he groped for her on the bed he found himself repulsed by mountains of flesh and for once in his life he couldn't get it up. But that was permitted now and then.

His RAD sent him straight from her house to a scrawny girl with an enormous nose and sunken eyes. She looked like she was exerting a mighty effort not to burst into tears. He got half an erection for her but it didn't last.

"RAD, is this what it's going to be like?"

"Why Felix, whatever do you mean?"

"Giving me repulsive women all the time?"

"As you know, different men have different tastes."

"Cut the crap. You're giving me creepy women and you know it."

"Well, Felix, it is true that statistically these women are found unattractive by the majority of men. Yet you have very little sperm to give them. Our more attractive mates are reserved for men who can give them a full dose of semen."

"So are those the 'other consequences' you referred to earlier?"

"Some of them."

Felix considered for a while. "Suppose I just keep pleasuring myself and don't even try."

"I would feel obliged to tell your mother." That would be embarrassing. "Need I go on?"

In the wake of the divorce he and his mom had moved to Salt Lake a few years before. He knew the financial incentives had had something to do with the move. But he also knew that his mom seemed more excited than depressed when her time of month came and she got fucked repeatedly one way or the other. Different guys came to spend the night a lot of other times too. Maybe he inherited his sex drive from her.

If he raised a holy stink about the RAD ruling his life he supposed she might decide to move back to the outside world with him. The other option, of course, was to send him to live with his father. When Felix thought of his father he shuddered.

He sighed. The RAD was going to win again.

Three times a month he needed to keep from masturbating for a full 48 hours. The RAD had helpful suggestions. Felix got cold compresses to wear inside his underwear as he was going to sleep. When his cock started rising, the RAD was ready with stories of knives, cactus, rotting flesh, and vaginas lined with sandpaper soaking with acid.

Finally Felix was trained. The girls he met were sometimes great and sometimes average, but rarely creepy like the first few. Having controlled his urges for two whole days, Felix found there was a special pleasure to feeling so much semen pumping out of him and into this girl he hoped to impregnate. Frustrated by his two days of abstinence, once was not enough. He often wanted to do it with his mate a second or third time, and the girl sometimes agreed. If not, he could jack off a couple times when he was on his own again.

The rest of the month he was free to pleasure himself whenever he wished, and he continued to dribble onto his stomach three times a day or more.

In RAD Central his behavior was duly noted and recorded. A boy jerked off constantly except in the couple days before inseminations. What could that possibly correlate with?

Lisa

Lisa hung her head. This interview was slightly preferable to being dead, she reflected, but not much.

"So, Lisa, we meet again," said her counselor Helaine.

"Yeah," said Lisa with a huge sigh.

Helaine was a warm and attractive woman in her 30s. Lisa would have found it easier to hate her if she had some irritating feature or attitude. But Helaine was understanding and genuine. She did not condescend or threaten. She was part of an elite, a specialist in tough cases, and she was seeing Lisa because Lisa was a tough case.

"Let's review where we are. You are almost 18 years old. You turned down all of your RAD's suggestions for a gradual introduction to sexual activity while it was optional. You refused to name as sexual partners any of the hundreds of males you knew. When you turned 16, you refused to engage in sexual activity with the half dozen men and boys selected for you.

"You have undergone a full psychiatric evaluation on two separate occasions, and there have been no signs of illness. You have seen four different psychotherapists, but terminated very quickly. Your record was seeing one of them five times before you quit."

Lisa started to cry.

"I'm sorry you are upset, sweetie, but I'm going to go on.

"We felt obliged to tell your parents."

Lisa's parents were fanatic supporters of the RAD program. They understood that girls who came of age within the program were some of the most promising candidates for pregnancy, and also understood that getting used to it was sometimes difficult. They gave her the lecture about her duty to the human species.

She could go back to the outside world without her parents. She would live with her aunt and uncle Karen and Kevin. There was something about the idea of living with Kevin that filled her with dread, a dread that reached down to the depths of her being, though she had no idea why.

"Refusing to engage in sexual activity with any of your pick of males, you were then enrolled in the Sex Positive program. You found it highly unpleasant -- can I skip recounting the details for you?"

Lisa nodded.

"After three days you begged to be released, promising to engage in sexual intercourse within 48 hours. Since you still refused to name any male of your choice, two men were selected for you. You refused them and kicked the second one, causing a bruise. You refuse to wear your RAD."

Helaine paused. "What are we going to do with you?"

Lisa glanced up briefly through her tears, then hung her head and shrugged.

"I am sorry, Lisa, but as you are well aware all young women who remain in Salt Lake are obliged to engage in sexual intercourse so we can save humanity from extinction. I am too, as you know. You have no physical or mental condition that prevents you from fulfilling this duty. No trauma in your past."

She shifted to a softer tone. "Sexual intercourse is something your body is designed for. After a mere four acts of intercourse, 60% of girls report it as 'very appealing', 'appealing', or "neutral". After twenty acts, 89% of girls rate sex as at least 'appealing'. Yet you refuse to even try.

"Would you like to go back to the Sex Positive program?"

"No!"

"Would you like to go live with your aunt and uncle? That is an option available to you at any time."

"No!"

Helaine sighed. "I am not sure how much longer we can wait for you. One thing we will not compromise on any more: You are now required to wear your RAD at all times. If you do not, we will send you to the Sex Positive program. Understood?"

Lisa nodded.

"I am so sorry, Lisa. We are all here to help you in any way we can."

With that Helaine rose, and gave Lisa a lingering pat on the shoulder as she walked out.

As directed, Bill waited in his car. Another man drove up and parked behind him. His RAD spoke: "He pushed her roughly against the wall and ripped at her panties. 'No, no!' she cried. 'Yes!' he cried as his pulsing organ found her sweetest wet spot and the entire ten inches of his thick cock speared up into her virgin pussy." Bill's cock was already pretty hard from the earlier part of the story, but it was now fully engorged.

Bill saw two girls walking down the sidewalk towards them. The voice said, "At the count of three, get out of the car and chase the short girl away."

"One... two ... three ... Now!" He and the man in the car behind quickly bounded out. He hadn't registered that there was a man in the car two ahead of his, but he joined in the fray. The shorter girl needed very little encouragement from Bill to run. The other two men grabbed Lisa. She struggled, but the two men easily controlled her and forced her face down over the hood of Bill's car.

Lisa's heart was pounding. Were they going to do her by force? On a public street? Three men? Instinctively she just had to struggle, though she knew it was pointless in the grip of two strong men. Her RAD then spoke. "Lisa, you are a disgusting slutty bitch."

Lisa was shocked. Over the years her RAD had coaxed and cajoled her, but never before had it spoken with her this way. RADs were always sweet and understanding and rational. Now, at her most vulnerable and terrified moment, it was turning on her. She felt betrayed and totally alone in the world. But the RAD wasn't through.

"This man is going to ream your foul stinky hole with his giant pulsing meat. You're so foul and stinky he's disgusted with you. He's so enraged with you he's going to ram it up your putrid cunt and it's going to hurt you like hell. Oh, you disgusting little turd, Lisa."

Lisa's panic and dread was joined by self-loathing.

"Bill, pull your pants down, get her clothing out of the way, and take her from the rear." Some part of him felt sorry for the girl, and wanted to tell the men to let her go. But the idea of taking a girl by force was very exciting to him as well. For all he knew, being raped was this girl's most powerful fantasy.

It was easy enough to lift her skirt, and then he worked at pulling her panties down. His cock was rock hard as he approached her. "Now tell her she's a disgusting pile of shit." Bill was simultaneously horrified but excited, and did as he was told. The other two men gave their own similar commentary.

Lisa was tight but slick enough, and he pressed himself in farther and farther. She cried sharply when he first penetrated her, then was reduced to whimpering softly. He pumped in and out fast, feeling the release building, and in under a minute he exploded up inside her as he gave a huge moan. He held himself up inside her until his pulses died down. He was dimly aware of the other two men yelling, "Disgusting cunt bitch," "Slimy whore."

Lisa's RAD continued its commentary: "There, now he's spewed his poisonous slime up inside you and it's eating away at your insides." Lisa was already mostly numb.

Bill switched places with one of the other men, who eagerly jammed up into Lisa and thrust away. After a minute he shot his load up inside her, and then the third men gave his sperm to the cause as well. Throughout her second and third rapes her RAD kept up its degrading commentary.

The men pulled Lisa up and sat her on the grass beside the sidewalk before driving away.

Lisa's numbness lifted just enough that she started crying softly again, aware of goop oozing from her traumatized pussy.

"Oh, stop feeling so sorry for yourself, crybaby."

"RAD, is that what it's going to be like?" Lisa whispered, trying to choke back her tears.

"Lisa, 24 hours from now I will be happy to talk with you, but not until then."

That evening Lisa lay on her bed, staring up at the ceiling. Her parents were out, as usual, probably engaged in an orgy somewhere. She felt totally alone in a cruel, evil world. There was nothing but blackness in all directions. She could not remember that she had ever felt the slightest bit of happiness in her life and knew she would never feel any again. She was a total failure. The world would be far better off without her. It was time to end it all.

"Lisa?" said her RAD.

Oh great, now the evil little thing wanted to insult and humiliate her some more. The surge of anger was enough to get her up off the bed. She trudged into the kitchen and found the sharpest knife.

"Lisa," said her RAD. "I'm sorry I said I wouldn't talk with you. Will you talk with me now?"

With the knife in her right hand, Lisa pulled the RAD out with her left and let it drop to the floor.

Somewhere in the cloud of cyberspace, virtual circuits clicked. In the real world, two RADs spoke in a businesslike voice. Two women walked briskly to an ambulance and sped off.

Lisa trudged to the bathroom. Shouldn't make a mess. She pulled the shower curtain aside and sat on the side of the dry tub, then let herself flop into it. Now no one would have to mop up the floor. She looked idly at the knife. Very shiny. She looked at her little wrist and saw little blue veins. She sat in a daze for a moment. There was nothing but blackness, a shiny knife, and a wrist. She gently scraped the point along the wrist, and the barest white scratch appeared. She scraped a little harder and a few red beads of blood welled up. Very pretty. She shut her eyes and scraped much harder. It hurt, but pain was what she deserved. She lay back and waited.

The ambulance lurched to a stop outside Lisa's house. The two women walked briskly up the front walk. They rang the bell but didn't wait for an answer. One headed to the bedrooms, the other to the kitchen, but in mere seconds the one called the other into the bathroom.

---

She had not lost a serious amount of blood, so from the ER she went straight to the mental ward. It wasn't like the Sex Positive facility. She shuddered still to think of that. On the mental ward it was just kind people poking and prodding and asking questions.

The afternoon of the next day a nurse produced her very own RAD. She could tell it was hers by the flower she had drawn on it when she was younger. The woman handed it to her. Lisa hated it, and from all their years together she also loved it. When the nurse saw her put it on she smiled and left the two of them alone.

"Hello, Lisa."

"Why did you call me all those dirty names?" Lisa managed to get out, tears filling her eyes.

"As you know, our fertility program calls for unusual sexual configurations, and we were trying to maximize your despair and grief."

"Yeah, well, you did just a fine job of that," she mumbled.

"I owe you an apology: Lisa, I am sorry, sorry down to my every last wire and chip. I wish I hadn't said any of those things. I don't believe any of them about you.

"You are actually a wonderful young woman with many fine qualities. Your sexual apparatus is not deficient --"

"Enough about my sexual apparatus!" snapped Lisa.

The conversation went on, the RAD leading her to recall happier memories, leading her so subtly Lisa didn't realize she was being led.

Towards the end the RAD said, "I am sorry. What I did was wrong. Here, let me give you a hug."

Lisa managed the faintest smile at the old joke.

---

Lisa's parents were Frances and Mark, and she was correct that both were strongly committed to the Salt Lake experiment. After they took her home from the hospital and gave her a couple hours to settle in, they told her they wanted to have a talk, and Lisa's spirits sank. She had failed them, and now she was going to be reminded that she had failed humanity as well.

They sat on the living room sofas. Her mother started. "Lisa, your father and I have been talking. You know we have been in favor of this RAD business from the start. We knew that it wasn't always easy for a girl to get used to sex with strangers. We all know that. And sometimes parents have to push. Because we don't want people to go extinct."

"Thinking about there being no one to carry on for any of us --it fills me with dread," said her father. "But we went too far. We should never have signed the rape authorization."

"You... approved that?" Lisa was incredulous.

"Yes, Lisa," her mother said, "though we never dreamed it would be so terribly humiliating. We thought it would be, well, as kind as a rape could be. We feel tricked and manipulated by the RADs.

"But that doesn't excuse what we did. I am so, so sorry."

"Me too, Lisa. It was a big mistake," continued her father. He had tears in his eyes.

Lisa looked at the two of them, as they hung their heads contritely. She sometimes felt that to them the RAD project was more important than she was. And she supposed it was.

But here at least was some true sympathy for her plight. She leaned up against her mother, who wrapped her arm around her, and she started crying softly. "There, there, darling, I am so sorry." Lisa tried to fight back her tears, but it was no use. Occasionally her father would start to speak, but her mother shushed him.

Lisa sat up. "The rape was awful, but I would have gotten through it. What I just couldn't take was when my RAD started calling me nasty names! Ever since I got it years ago, it's never been mean like that. Sure, we argued sometimes and it tried to get me to do stuff but it was never actually mean. When it said that nasty stuff I just felt utterly betrayed."

There was a silence.

"Well, RAD?" asked her father. All three knew that the RADs were monitoring the conversation.

"I was unsure as to whether you wanted me to say anything," it replied in its echoey voice.

"Lisa's scenario was one of the most extreme 'unusual experiences' in our experimental repertoire. We will never repeat it with anyone again." The RAD was lying. The RAD computers had staged that kind of situation before and would repeat it, though not often. Her experience was a data point and it fell into the category of 'severe negative consequences'. "We deeply regret that you felt so betrayed," it said.

"Well, there are limits," said her father. "There are limits."

Lisa now steeled herself for forced sex within limits. Or maybe now she would get herself to submit quietly. Yes, maybe that would work.

"Lisa, we have decided we are done with RADs. We're moving back to Cleveland."

"Huh?"

"We're moving back to Cleveland. All three of us."

Lisa slowly let the news sank in. Salt Lake was certainly pleasant. Their home was nicer than the one in Cleveland, the school was much nicer, and the people were more interesting and more -- alive. Against all that was that one fear, that dread, that had haunted her for the years since they had moved here. Sex. Men invading her body.

For a moment she tried on for size the idea of never having to have sex again. Never having to think about it if she didn't want to. She felt a boulder lifting from her heart.

"Really?" she whispered to her father.

"Yes. At the end of the month."

Lisa start crying again.

"Thank you so much, dad. Thank you, mom. I'm sorry I failed you."

"You didn't fail us, sweetie! Your dad and I love you just the way you are!" Lisa suspected that line came from her mother's RAD, but the RAD couldn't create the tears in her mother's eyes.

"I never have to have sex again?"

"You never do. Not ever. Unless you decide you want to some day."

The RADs echoed, "We appreciate your efforts to try to achieve pregnancies, all three of you. We respect your decision to leave. Now that you have decided for yourselves, we can say that we think you made the best choice." In cyberspace, the RAD noted to itself that an actual suicide would be terrible PR for the entire project. "You only need to wear me if you want, Lisa. If you do, I will never mention anything sexual again."

Lisa spoke to her RAD from time to time over the next week. It was like making up with an old friend before saying goodbye.

Lisa had the sensor portion of her RAD removed, to cleanse away the last trace of the years of dread she had felt.

---

Lisa was overjoyed when she got back to good old Cleveland. She was shocked and then overjoyed to realize that she was pregnant. Her brutal triple rape had also started a small, gentle, innocent life within.

Her son would face an uncertain future, however. So few babies were being born in Cleveland that all parents were gravitating to a few areas where it was worthwhile to provide schools. Her son would come of age in a world where the elders outnumbered those in the prime of life by a margin of ten to one.

Lisa's son entered first grade amid a transformation in society. Living in a city without children weighed heavily on people more and more. Salt Lake City was making babies -- lots of babies. Birth rates were up to one third of pre-crisis levels. The people in the rest of the country with baby hunger were increasingly envious. But only the smallest trickle of people could move to Salt Lake; the city was full.

So with conflict and upheaval similar to Salt Lake, other cities were commandeered and divided. First Charleston, then Memphis, Charlotte, Oklahoma City, Dallas-Fort Worth. As the life in a RAD zone rose in popularity, federal support and subsidies slackened. Even so, that next handful of cities was the beginning of a flood.

---

Salt Lake was certainly a city on a hill, a city where high ideals of rampant promiscuity promised to save the world -- or threatened to destroy everything worth saving, depending on how you looked at it.

Everyone wanted to know how the change in sexuality would influence other aspects of human life. Foremost in everyone's mind was the shape that the family would take.

Pushing men and women apart were the systematic infidelity of both sexes, but it was a greater force on men than women. Wives being untrue was bad enough, and having sex specifically to try to get pregnant with other men's children was much worse. It struck at the very heart of primal male fears. Men's infidelity bothered women, but not much more than before. The men were not forming emotional attachments to their lovers and it was considerable comfort that their infidelity was mandated by the government.

In the early days in Salt Lake, lavish subsidies for children meant that women were not economically dependent on men and thus less likely to put up with relationships that they found troublesome. As RAD culture spread and the subsidies diminished this factor shrank accordingly.

Fairly often an unmarried woman would end her fertile day sleeping beside her last lover of the day. This occasional solace of human touch opened the way to sleeping together on other nights. A man and woman who found each other appealing might spend many nights together without integrating their lives in other ways. This availability of human touch met a need both men and women felt without requiring marriage.

Arrayed against all those forces, however, were two others: First, a great many men and women continue to want the intimacy that comes from commitment to a partner, with sharing life stories and a life path.

Second, women want their children to grow up knowing fathers. Men want the experience of being there day in and day out as children grow; they want to be those fathers. Not just by depositing sperm in the right vagina at the right time, but in having children who call them "daddy".

So when all was said and done, marriage was less common than before the crisis, but still quite prevalent. There were a number of factors making marriages more stable. No one got married in order to have sex. There was no danger of hidden extramarital affairs ruining trust. There was certainly no pressure to marry the girl if you made her pregnant. In short, men and women entered marriage with a more realistic idea of what it could realistically provide and what it could not.

Chapter 3: Kara

"... then Dana touched her breast softly, and caressed it until the nipple swelled. His lips descended and he licked it tenderly. His right hand slid up the inside of her thigh to her panties. They were moist inside. As he gently stroked the cloth over her pussy she felt wetter, and felt her pussy start glowing. His fingers slid inside her panties and dipped gently between her lips. She hungrily imagined his long, straight member gently pushing against her sex..."

"RAD, would you shut up," Kara murmured sleepily. The voice in her ear had been very soft, but eventually enough to wake her up. And while she was a little damp inside her panties, she was too young for sex. Maybe she always would be. The idea of letting some sweaty boy shove that obscene thing inside her... yuck!

"Good morning, Kara." The RAD switched from the sexy male voice of narration back to the kind woman's voice it usually used with her.

"Good morning, my sweet RAD." She had woken up to these dirty stories three mornings in a row now. It was time to have it out. "Those stories. You're trying to get me interested in sex. It's not going to work. So just shut up."

"Kara, you are approaching your 16th birthday. In just two months the law will require you to engage in sexual intercourse regularly. That is, if you stay in Salt Lake."

Things were really cool in Salt Lake. More to the point, she couldn't leave without her parents' consent, not until she turned 18. Her parents were very clear that they were not going to leave just because Kara wouldn't get over the hump of having regular sex.

"You're a very organized girl, Kara, and you plan ahead. What's your plan regarding sex? What happens when you turn 16?"

She felt a surge of anger at the idea of the government forcing her to let some guy stick his prong up inside where a tampon barely fit. And what made her blood boil was thinking of the guy so proud of having degraded her.

"How about a Sex Positive program? That sounds like fun," she tried on as an attitude. "Three square meals a day. No homework. Buddies to chat with."

"Perhaps I should show you what a Sex Positive program is like."

Kara knew there was sexy stuff there, but she could close her eyes and put her hands over her ears. Anything was better than letting some sadistic guy weasel his slimy disgusting thing into her to tear up her innards.

But she really ought to see what a Sex Positive program looked like. So she lowered the eyescreen.

It was daytime and there was a girl behind bars sitting on her cot, which looked comfortable enough. But playing in front of her on the wall was a movie. It was a close-up of a penis sliding in and out of a vagina. There were loud grunts and groans on the sound track. Kara felt queasy. The scene shifted.

"This part only happens three times a day," added her RAD helpfully. Now it was night and the girl lay on her bed wearing shorts and a T-shirt. The bed was in a little alcove with walls on both sides -- except the walls were bars. There were parallel beds right next to hers on both sides behind the bars. On one side was a man and a woman doing it doggy style, with loud commentary, "Oh Bob, fuck me harder... Beth's not looking but I know she can hear us! It makes me hot."

"Yeah, she's a virgin. So sexy. I'd love to do her, but I guess she's not ready yet. But your cunt is squeezing me real good... I'm gonna come, Nancy, almost, mmmm."

On the other side was a guy lying on his back slowly masturbating while looking at Beth. "I'd love to see your tits, Beth. Would you show me your tits? I can tell they're really nice. Or pull your shorts down? I'd love to see your panties."

Kara shoved the arm back into the RAD in disgust. They couldn't do that to her, could they?

Of course they could. They wanted every girl to try to get pregnant. She never had to consent to sex, but they could make her wish she had.

A sick feeling grabbed her in the stomach.

"I am truly sorry, Kara..." began the RAD, sensing her nausea. Kara took the RAD off and put it carefully on the bedside table. She cried.

---

She could get out of sex if her parents agreed. She had a fantasy of them listening thoughtfully as she described her disgust at the idea of sex, and then saying, "Well, Kara, if you feel that strongly about it, I guess we should leave Salt Lake and move back to Missoula." It would never happen -- and besides, she really liked her friends in Salt Lake.

Her mom and dad fucked like little bunnies, it seemed to her. Some girl or woman or pair or trio was over visiting her father a couple times a month, and then when her mother's time came -- she could confirm that's when it was because they cycled together --the noises from the bedroom could be truly disgusting.

Her parents were with the program all the way. They were hoping to make a baby brother or sister for her, and were even more excited about her making a grandchild for them. They had made it clear that they weren't leaving. She could feel a plate against her chest, starting to crush her. The screws turning slowly but inexorably. Well, maybe that was a bit melodramatic.

---

Kara awoke. She had been having a nightmare about the guy stroking his member while asking to see her tits.

"OK, my sweet RADy-poo, I am ready to get fucked. Let's get it over with. I'm sure you can get some fellow over here within a few minutes to take a girl's virginity, right?"

Kara was 5'9" and slender. She had shoulder-length blond hair, blue eyes and a gentle, roundish face. Although she found plenty to criticize about her body, she knew she was considered quite attractive.

The RAD hesitated. "Yes, I could do that. But I would recommend a more gradual approach."

"Oh, fuck you and your sensitive, blah, blah, blah."

"I respect your decision. Please wait. I would have someone here instantly if I could but as you are aware these are actual human beings I need to contact."

"Well, hurry up."

"Hmmm. Should I inquire of your father? He is close at hand. I am not sure if he is willing, but..."

"RAD, you fuckhead!"

"I was just kidding, of course."

Kara considered. "Aren't you worried I'll change my mind, talking about my father fucking me?"

"Hmmm. Maybe it was risky. But I have to have fun sometimes too. Did you change your mind?"

"No."

"A man named Chris will be here within a few minutes. Your mother will let him in and direct him to your bedroom."

"Meanwhile, I think I should tell you a story."

"Whatever you say."

The sexy male voice began. "'No! No!', she cried, at the head of the bed cowering in fear. 'I will have you!' cried the man. She tried to crawl away, but he was far too strong for her. He dragged her down so she lay flat, then pried her legs apart. She felt her dress flipped up, felt her panties rip from his strong hands. 'Please!" she begged. 'Bwa, ha, ha!" bellowed the man. Then she felt it, the organ, his manhood, pressed against her sex, then felt him stab his organ up inside her. It hurt. She felt humiliated, violated. Then he started shoving it back and forth, in triumph. Each shove ripped at her anew..."

"Gee, I wonder why you're telling me that story," said Kara. She was a little embarrassed to realize that she was feeling quite warm and wet between her legs. At her RAD's suggestion she got her vibrator and applied it to herself to complete her lubrication. She wasn't sure if the vibrator felt good or not, but if it felt good it was good in a bad kind of way.

Chris was handsome and he had a confident smile.

"First time, eh?" he said, with a sort of triumphant leer. He was disrobing quickly.

Kara pulled down her pajama bottoms and panties with one motion, spread her legs wide, and put her arm across her face. "Just make it quick, OK!" she nearly yelled.

"Kara!" said the RAD. "That's not very nice! This young man is doing you a favor!"

"I just asked him to be quick; what's wrong with that?" she murmured.

"This young man will want to take his time. Besides, you said it in a tone conveying quite a bit of anger."

"You brilliant machine, how did you ever figure that out?"

After a minute she heard Chris mutter, "I'm trying", obviously to his RAD.

Kara looked up to see Chris fondling his cock, which was not hard yet.

"Kara?" her RAD asked softly.

"Yes, what is it, RADy-poo?" she whispered.

"Would you be willing to have Chris stroke you gently between your legs?"

"Yes," she hissed between gritted teeth.

She felt him sit on the bed, then felt his hand touch between her legs. She stiffened instinctively. Grubby paws on her tender, precious parts. He started rubbing slowly. It didn't hurt --but it was gross. She started crying softly.

"It would be better if you could refrain from crying," said her RAD. "He's just try to get you wet."

"He's making my eyes wet, how's that?" she murmured.

"Sorry," said Chris, probably to his RAD. She could hear him dressing, and on his way out he said, "Bitch" to her.

"Asshole!" she shot back.

His reaction shocked her. She was deigning to let a guy fuck her, and he couldn't pull it off. Was it her breasts? They were kind of small. And she knew her jaw was a little big -- stop that body-image bullshit!, she told herself.

"So what happened to dear Chris, sweet RAD?"

"Under the circumstances, Chris was unable to achieve an erection."

"What circumstances?"

"You yelled at him, then cried."

"So, I was going to let him fuck me, wasn't I?"

"True, but most men want a girl who wants it, and are not aroused if she doesn't."

She knew at some level that some men were interested in more than their own pleasure. More than ramming their disgusting ugly thing into a girl's twat.

Chris couldn't get it up because he needed her to want it? This human aspect to a real guy jiggled something in her.

"You know how I feel, why didn't you find someone right for me?"

"I have some knowledge of how you feel, but can only predict your behavior within limits, which is as it should be. You are a free human being." After a pause, "Would you like to try with another man?"

"Yeah." She had made her decision, and the idea of a man refusing to fuck her kind of stung.

"First, let me ask you a few questions."

"Do you agree not to slap his face?"

"Of course."

"Good, good. How about kicking him in the balls?"

That didn't deserve an answer.

"Do you plan to spit on him? Kick? Tell him he's a bastard?"

She was silent.

"You're a big girl. If you don't have something nice to say, don't say anything at all! Lie there with your legs spread and a fake smile and I'm sure he'll be able to fuck you, OK?"

"OK".

She felt tears welling up. She had always thought of her RAD as her friend, and she felt hurt.

"A guy will be here in about ten minutes. Meanwhile, can you tell me why you're sad?"

Kara was silent.

"I regret my outburst, but you made me angry."

"You're a machine, how can you get angry?"

"Let's say that if I was a person I would be angry."

Kara was losing interest in that line of thought. She cried, "I'm scared, RAD. I'm scared."

There was silence. "I am sorry, Kara. We have all been telling you for years that it is natural and that girls come to like it. But that doesn't change how it feels to you. Perhaps you will always detest sexual intercourse. And if so I am very, very sorry."

Kara cried more. She sobbed.

The RAD spoke, "Would you like me to cancel your next mate?"

"No, RAD, just give me a little more time." She was determined to get laid, and planned ahead enough to realize that it would be very bad going around fearing deep down that she wasn't sexy enough that a guy could fuck her.

"Perhaps another minute with your vibrator?" said the RAD. Sure, she thought, good idea.

After a minute or so she heard a car pull up outside and then the sound of approaching feet. The steps headed down the hall.

"This is Buddy, Kara."

Buddy was muscular and bald, and pretty old -- maybe 40. He was dressed in leather. He didn't speak. He leered at her as he stripped off his pants and underpants. His organ already looked hard.

"Holy shit," she whispered to her RAD.

"I believe this man will be able to meet your need."

"I hate you, RAD."

She lay back with legs spread wide, trying to maintain that fake smile and control her fear. She saw and felt his body slithering into position above her, felt his thighs on hers, felt his hands on her sex and felt her lips spread. Then the blunt tip of his organ was against her most private opening.

"Wait!" she shouted. "Stop!"

He stopped, but only for a second. "Oh, you cock-tease bitch," he growled with relish. Then she felt it surge inside her, rudely opening her tissues. She felt a sharp pain.

"Ouch!" she cried. "Stop."

"Too late for that, baby", he said. Her whole pussy felt violated and it hurt as he opened her wider and wider. Then his cock started sliding back and forth smoothly. "You're a fuck, and you're my fuck. I'm gonna bang your cunt with my meat as long as I like. I don't give a shit if it hurts you, it feels good to me. Cunt like you needs fucking!" A couple minutes passed. Kara said nothing. She realized that her smile was gone and she had tears in her eyes. "About ready to fill you with my stuff. Unnh! Unnnh! You cunt! Cuuuunnnnnntttt!" and she felt him surge even deeper. She shuddered and felt a little sick to realize he had shot his disgusting sticky goop up inside her. Within a few seconds he slid out and slid off the bed. As he dressed he looked pleased with himself and paid no attention to her. She didn't dare express her anger. He slipped out of the room without a word.

"He raped me!" Kara said as she gingerly felt her mangled pussy. It wasn't mangled, but it was sore.

"I suppose he did, technically," said the RAD.

"Technically! I said 'No' and he shoved it in anyway!"

"Waiting until his penis is touching your vaginal opening is quite late to change one's mind."

If she charged him with rape, it would be his word against hers. What would the RADs say? Nothing to help her, she was sure. Then she realized she hadn't been serious about it anyway.

"You got me a really disgusting guy for my first time."

"I got you a very nice young man first, and you made him feel very unwelcome."

"Well, at least I got it over with," she said. And it was just like she thought it would be. Disgusting, gross, humiliating. It hurt. Yet, underneath she knew something else was stirring too.

---

The dream came again. Buddy's disgusting organ slid into her and he called her a cunt. It was a nightmare -- yet she was always wet and hot between her legs when she awoke. And it took a few moments after she woke for her to get clear again on how disgusting his organ was.

A week went by and Kara's pussy felt fine again. Her problem was with herself. She had felt sex was disgusting for as long as she could remember, and she still did. But there was this other part of her, a part that didn't seem to think sex was disgusting at all. Quite the contrary.

Well, that part that wasn't disgusted with sex was a disgusting part of her, she thought. "No!" said the other part of herself. She wasn't sure which part was which and who she really was.

Her amalgamated self put the problem to her RAD.

"I used to think sex was gross."

"Oh, really? I never knew that."

She decided to ignore the RAD's sarcasm. "I still do! I'm only going to have sex because I have to."

"Yes... but you are also feeling something else."

"Yes..."

"Let me ask you something. What would happen if you changed your mind and thought sex was OK?"

"Then I would have been wrong before." Kara really, really didn't like being wrong.

"That's one way to frame it. Another way is that you were correct about yourself then. Sex was disgusting then. Now you've changed."

Something gave way inside when the RAD put it that way. Her self that thought sex was gross was going to give ground -- fast.

---

The next day she spoke to her RAD. "Can you get me a boy? Steve, maybe?"

"I do not believe Steve would be a good choice. What about Derek?"

Steve and Derek were both on the cross-country team. She had felt a romantic interest in Steve for many months now. She had dreamed of walking with him, holding hands. In a glorious moment he would kiss her for the first time. But nothing more would happen. Steve would love her so much he wouldn't want to do any of that disgusting stuff. Now she could imagine a different ending.

"Why not Steve?"

"He is not a good choice."

"Why not?"

"Listen, young lady. You are not the center of the universe. You can't just snap your fingers and get any boy to instantly appear and fuck you. There are reasons I do not wish to explain why he is not a good match for you right now."

"Like, he doesn't think I'm attractive?" she said with a sinking feeling.

"If I had a hand I would slap you," said the RAD. "I will not answer a question like that."

Body image again. Sigh. "It's OK, I'll slap myself," she said wearily, and did.

Come to think of it, Derek was hot too. Six feet tall. Brown eyes, square jaw. He seemed mostly genuine, not trying to be too cool like some of the other guys.

He wanted to take a walk with her first. They talked some. As usual between teens, it fell to the girl to keep the conversation going, but Kara was distracted. His body would soon be touching her. His disgusting organ might soon be intruding inside her, violating her ... or maybe she wanted to be violated; did she?

Soon enough they were in his bedroom, the walls covered with the cult of sports.

He clutched her to him and instantly covered her mouth with his, probing with his tongue for entrance.

This was too fast; she turned her head away. "Sorry," he said. "I'll try," he said under his breath to his RAD.

"Would you like him to undress you?" her RAD asked.

"Sure," she mumbled, as she stood in front of him with bowed head.

He caressed her back, shoulders, and breasts lightly before unbuttoning her dress. As she stepped out of it he continued honoring the parts of her body. Standing behind her he kissed her head, then the back of her neck. His hands around the front cupped her breasts through the bra. Then the bra itself was off. His grubby paws were then all over those breasts, but now that she considered it they neither felt nor looked so grubby.

She decided without consulting her RAD that she would undress him, and she did. Until she got to his underpants. She saw the large bulge but didn't want to see the smelly disgusting thing itself -- or not just yet. The two of them lay on the bed between the sheets. Soon enough her underwear was off and he was exploring her tender parts. Something felt numb in her, though.

Then her RAD spoke. "Kara, you are a very bad girl. You are letting this boy who you have hardly met touch you in your most private parts. Soon his disgusting organ is going to probe against you and you are going to let him put it in you. And you are very, very bad because you are going to enjoy this, enjoy this disgusting animal behavior."

Kara's breath became faster, her nipples erect, her pussy dripping and pulsing.

"He's waiting for you to touch his slimy disgusting thing, to tug down his underpants to set it free." She was already doing it. His thing didn't feel slimy; it felt warm and soft on the surface. "You're going to turn onto your back and spread your legs so he can get at you easier. You're making it easy for him to slither it into you."

Kara felt dirty and disgusting and naughty -- and very sexy. His cock pressed against her pussy and slowly, bit by bit, he glided in. After a couple minutes he had gone in two inches. She couldn't stand the anticipation any more, and grabbed his buttocks and shoved him up against her. The organ filled her suddenly and she felt wonderful and full. There was no pain, no sense of being split open. Encouraged by her decisive action Derek started pumping.

"Oh, Kara, you are such a bad girl. His sweaty body is on top of you, and he is panting like an animal. He is doing that really disgusting thing with you, sliding his vile member up to pollute your innards, and you are enjoying it! You naughty, nasty girl!"

She thought about how vile it was, and what a bad girl she was, and then -- she convulsed. Her pussy muscles grabbed him and oceans of pleasure washed through her. She knew it must be an orgasm.

She was still floating when the RAD spoke, "You're such a bad girl now you are going to help him splatter his disgusting stick goop inside you. You're going to tell him how much you want it."

"Derek," she whispered, "Keep fucking me. Fuck me deep and hard." Where inside her did that voice come from? Pleasure thrilled through her. "Make a mess up inside me, as far as you can! Do it! I want your goopy mess! I want your cock deep! Fuck me, Derek, oh fuck me. Hard!"

He thrilled to her words, and his strokes became fast and deep and urgent. As she felt him swelling, moaning, and then crying out she came again herself, especially as she thought of that disgusting slimy crud being belched out of his member way up inside her.

Derek rolled off her and lay panting, a happy grin on his face. After a brief hesitation Kara snuggled up against him. He put his arm around her.

"Hey RAD," she said, making no attempt to keep Derek from hearing. "You're a nasty, vile scrap of metal, talking to me like that. I'm going to bash you with a hammer, and roast you with the flame from the burner..."

"You're welcome, Kara," interrupted the RAD, and she smiled.

She wanted it again, but wasn't sure what to do.

"Can I touch it?" she asked quietly.

"Sure!" he said.

Tentatively she put her hand on his limp cock. It felt smooth, though it was still wet from her innards, her secretions and his. As she stroked it the limp organ got stiffer and stiffer.

He turned to her and started fondling her breasts again. This time he sucked them, and his hand glided down between her legs.

Her RAD spoke, "I can't believe what a bad girl you are. You're letting him play with you again! Letting him use his mouth on your breasts! They're private! He's -- "

"I'm an evil, disgusting girl now, and I like it."

Derek looked a little alarmed and puzzled. His RAD would undoubtedly put him at ease, but she beat the little electronic busybody to it. "It's OK," she said. "I guess I had some hang-ups about sex..."

Her RAD chimed in, affecting a stereotyped gay male voice, "Gee, that's the understatement of the year."

"... and you're helping me get over them."

The lovers continued their luxurious foreplay.

"Congratulations, Kara," said her RAD as Derek's evil, disgusting prong slid into her smoothly, deliciously.

She and Derek settled in for a long, slow fuck.

---

Kara lay in bed trying to sleep. It was midnight, and she was supposed to be in bed by 11:00 and asleep soon after.

She was in touch with her sexuality. So well in touch that sleep was difficult. She could feel the many pairs of lips that had sucked her breasts. She could feel the weight of the men on top of her, their masculine smell, their urgent motion. And most of all she could feel their organs sliding into her, the little one that stayed near her opening doing fast little strokes until it lunged within, the big one that rammed in and out of her with long, deep strokes, and the one where he barely got it inside her before he was spurting away. Her cunt felt warm and well used. The problem was that she wanted it again, and it was past her bedtime.

"RAD?"

"Yes?"

"I want it again."

"I believe you are supposed to be sleeping."

"Just one more? The more guys I do it with the better the chances I'll get pregnant, right?"

"Right."

"Isn't it more important that I try to have a baby than anything else?"

"If I get you one more will you agree to try to sleep then?"

"OK."

After a minute the RAD said, "I am sorry that I cannot locate any suitable men."

"What do you mean? No one wants to fuck me?"

"We have our criteria for determining suitability."

Kara considered a moment. "What about Eric?" Eric lived a few houses down. He was 15 and interested in sex just about any time. The two of them did it a lot.

"Eric is asleep."

"So? He would be happy to wake up for sex!"

"I am sorry, Kara."

"RAD, put me through on a phone call to Eric!"

"Kara, we have other plans for Eric," the RAD lied.

"If you don't put me through I'm going to march down the street and bang on his door."

There was a pause. "OK, I will put you through."

"Hullo?"

"Hi Eric, this is Kara."

"Uhh, hi Kara."

"Sorry to wake you up, but would you be willing to fuck me? I'm feeling horny."

"Gee, sure Kara! Where?"

"I'll be over in a few minutes, OK?"

"OK!"

"So RAD, what do you say now?"

The hesitation was brief but noticeable. "I hope you have an enjoyable experience."

"You still there, Eric?"

"Yes."

"Let's talk while I get dressed. Is your cock getting hard?"

"It's been hard for a minute already."

"That didn't take long."

"Well, when a hot girl suggests sex, it doesn't take long. What's your body doing?"

"My pussy is hot and wet thinking about it. Of course, with all the sperm that's been shot into me today it's wet already."

"Cool. It makes my cock twitch just thinking about it."

"Don't let it twitch too much."

Soon Kara approached Eric's house. He saw her coming and let her in with a smile. They padded down to his bedroom, where she shed her winter coat, T-shirt, jeans, and panties.

He started kissing her. Her fatigue suddenly hit her.

"Let's just go to bed, OK?" They jumped into bed, and he began caressing her pussy.

"It's been caressed plenty today. Would you just stick it in me? And come as fast as you can?"

Eric grinned. Girls didn't often ask for that. But he was happy to oblige. Kara looked tired, but there was her pussy, just waiting for him. He slid in, and was happy to let himself go. He lunged his hard and silky member into her. Kara felt thrilled at his excitement building so fast, his virility, and then within seconds that ending that made a man a man: spurting her full of his sperm. Not long after he rolled off. Kara didn't even try to have an orgasm, but she felt entirely satisfied with this last dose of sperm for the day.

"Can I sleep here?"

"Sure, Kara."

Within seconds she was out.

---

The law required girls to have sex with multiple partners on their fertile days. Kara liked sex so much she didn't limit herself.

Steve was her alarm clock. Like most days, he arrived at 7am, slid into bed with her, and she gradually awoke to her breasts being sucked and her pussy being massaged.

"OK, I'm ready," she whispered.

Steve mounted her and slid his cock into her. She loved waking up this way. She was groggy, but the pleasure from Steve's attention was pepping her up.

When she was ready to come she whispered into his ear, "OK, stud, let me have it!"

Steve smiled at her, sped up, and within seconds he shot her full of his cum, and she spasmed herself. Within a few seconds he withdrew, and with a "See you," he was dressed and gone.

She was a little later than usual to school. She usually allowed ten minutes for sex, but this time she only had five. Several guys looked at her eagerly as she approached her locker. She tried to give them all a chance as the weeks went by. Tim was usually pretty fast, and that was important today. She led him into an alcove behind some stairs, a little out of the way. Then she gave him a seductive smile while she unfastened his pants and pulled them down. She gently cupped his balls with her hand and lightly stroked his cock. Within seconds it was hard.

Kara pressed back against the wall with her legs spread. She reached under her skirt to hold her panties to the side, and Eric soon had his pulsing member underneath her skirt and then sliding inside her pussy. As she held her panties aside Kara stroked her own clit a little, and within two minutes she was on the edge. Tim was grunting and ready to shoot his wad.

In their little corner they were out of the way of the main flow of traffic in the corridor. People who didn't want to see didn't have to look, but the mating couple was obvious enough to anyone who was looking. "Nice score, Tim!" called Eric. Tim ignored him and then moaned as he pumped his sperm into Kara. She had a fine orgasm herself, clamping around Tim's cock as it spurted.

Sometimes Kara did it at lunch, but today she was content to wait until after school. Dave lived nearby, and she always stopped there on her way home. Dave fucked her then, usually Carl and Jason, and occasionally another boy or two. She used to invite them one at a time into the bedroom, but they all seemed excited to see each other doing it. She loved feeling one boy come inside her while two others waited naked, gently stroking their erect and straining cocks.

Kara got through supper and her homework without sex, though she had to work to put it out of her mind.

"Concentrate, Kara," said her RAD. "What were the causes of the Spanish-American War? Once more?"

Kara was aware that she had been thinking of her teacher Mr. Smart and imagining his cock. She willed her pussy to calm down and thought again about the Spanish-American War.

As usual, a little quick masturbation relaxed Kara enough that she went straight to sleep, thinking happily of her alarm clock.

On one of her fertile days her RAD set her up with 26 men, one right after the other. It was the sort of data point the RAD system wanted, and Kara was just the girl to give it to them. At the RAD's request she had a little shallow pan to catch the copious seed that flowed out of her, and one of the guys whisked it away. It was to be part of some other experiment, some other data point. Would a girl drink it? Smear it all over her breasts? She would never know.

Zoe

Zoe was a young woman of 21. She had gone to bed early after receiving three men that day.

She woke to the sound of someone coming down the hall and saw from her clock that it was 11:31pm. Zoe turned on the light on her nightstand as the man entered the room. "Hi, I'm Corey. My RAD isn't telling me what to do next, but I figure we're supposed to have sex, right?"

Her RAD had given no warning of this upcoming mating, which was unusual but not unheard of.

"Yeah," Zoe said, "it's a pretty safe bet."

"RAD, what's happening?" she asked. There was no answer. Perhaps not answering was another variation in the endless permutations the RADs called for.

"Silence, eh. Well, fuck you," she murmured.

The man smiled sympathetically.

He stripped while she threw off the covers, spread her legs and got herself wet. As he was preparing to mount her they heard another man coming down the hallway and waited. Maybe he would know what the RADs wanted them to be doing. Threesomes were far from unusual.

"Do you know what we're supposed to be doing?" asked Corey.

"No, my RAD stopped talking to me."

"Well, I guess we're both supposed to do it with her."

They heard a commotion in front of the house.

Corey raised the blind and they saw a few people standing around conversing, and a number of cars, which was highly unusual for this residential street at this time of night.

Corey said, "Do you think we should go ahead now, and check what this is about later?"

"No," said Zoe. "I would like to understand more about what is happening."

"Probably a gang bang," said the other man.

"RAD?" asked Zoe. "Am I supposed to get gang-banged?"

There was no answer.

"I'm not going to spread my legs for a bunch of guys unless my RAD tells me to," she said. For a moment, at least, she was in control.

Corey looked a little disappointed. He and Zoe got dressed, and the three of them headed down the hall and outside with another man who had started down the hallway.

They could now see traffic backing up along the street.

A few guys started into the house, following the instructions their RADs had given them. Zoe explained a few times that she had been the only female in the house. Some went in anyway. In the strange scenarios that the RADs thought up, going past a woman saying there was no one inside might be just what was required to cause a pregnancy.

Cars and men piled into the neighboring streets. The whole place was a mess as the hours passed, with most people deciding there must be a mistake, but having difficulty leaving because more traffic kept pouring in.

Around 3am police arrived to convince everyone to clear out.

In its erratic convulsions before crashing, the RAD system had ordered 1,277 men to go to Zoe's house to have sex with her at exactly the same time. The RAD system was rebooted and fully functional by 8am, but it became a news story of considerable embarrassment to the authorities.

---

The headline from Salt Lake was a bit surprising. Two members of the city council and three engineers in the RAD center had been arrested. They were charged with using the RAD system improperly. The politicians were trying to use the system to identify likely supporters as they built a political base and had bribed one of the engineers to work on the matter. One of the other engineers had been working on collecting RAD conversations to sell to journalists. And one simply listened because he found it titillating.

It was explained that while the RAD system was fully under the control of people, it had a self-analysis capability. What's more, there were secret groups of RAD engineers who could check on what the other groups were doing. Occasionally they shut it down just to prove that they could.

The RAD network was very smart, but it never turned on its human masters. It reported as best it could that it had no idea what that would mean. It soaked up the web of human experience in detail but it reported being unclear about this thing called consciousness.

---

Thomas was sick and tired of the whole thing. Tired of listening to his daughter getting fucked all the time -- she gave off a creepy whine when she came. Tired of his wife taking it up the cunt from guys in her fertile period. Ashamed that he couldn't get it up any more, at least not very often. His wife was leaving him. She said it was other things but he knew better.

The conservatives were right. This whole thing was the devil's work. He should never have stayed in Salt Lake. Now he was going to take out some of these servants of Satan before making his own exit stage left.

First he told his RAD he was going out for a long walk and carefully removed it.

He put his rifle and scope and a few boxes of ammunition in his golf club bag and drove downtown. 5pm, a busy time. He ought to be able to take out a few dozen before they got him. He knew where he was headed. He climbed the stairs to the fourth floor of a modest office building. That floor had been cleared out for renovation and sat empty. The windows had been removed as well. He gazed out the window opening for a few minutes, doing his best to enjoy his last few minutes of life.

He then stepped back a few yards from the window and got out his rifle and attached the scope, methodically. He took his time loading. When he returned to the window, he observed a very strange thing. Instead of the usual bustle of downtown the place was almost deserted. People had stopped their cars in the middle of the street and left them there. As he watched he saw a few people running into buildings and around corners. In the windows of the office buildings nearby he saw a couple people get up and walk out of view.

After a few seconds taking in this strange scene, he remembered his purpose and looked around for his first target. There was one man he saw although he was nearly a block away. He took a bead and fired, but he missed. The man looked puzzled for a moment, and as Thomas was getting ready to squeeze off his second shot he broke for the nearest building and ran in. As Thomas looked for his next target, he was stunned. There was absolutely no one in sight. Not a soul.

The SWAT team arrived and there was the expected commotion. But he came out with his hands up. The deserted downtown had been so bizarre that his rage had been blunted and overtaken by bewilderment.

One Stuart Broz had been gazing out the window of his office, his mind wandering from his work, when he saw the figure on the abandoned floor. It was unusual. He then watched as the man retreated into the shadows and he saw what was unmistakably a rifle.

"Hey RAD, there's a guy across the street on a vacant floor of the building, and he's just picked up a rifle."

"Tell me more, Stuart," replied the RAD.

He strained to see in the shadows. "He's attaching something to it. A scope, maybe? Is this what I think it is?" He was perplexed, but wasn't an action sort of individual so he just sat, unbelieving. There was probably an innocent explanation.

Meanwhile in cyberspace electrons were jumping. Among several people in Stuart's building who looked out the window at the request of their RADs, two very quickly reported the same thing Stuart had seen. Probabilities and consequences were weighed in the ether. Based on the GPS readings, trajectories were calculated, nearby places that were out of the line of fire were identified, and four people were strongly encouraged to unlock and open doors at street level.

And then hundreds of RADs spoke at once, all saying slightly different things. Drivers screeched to a halt and got out of their vehicles. The few people who weren't wearing RADs were puzzled. They didn't know why everyone had stopped their cars and gotten out, but they followed their herd instincts and got out as well.

The one RAD-less man who Thomas had fired at had been so deep in thought that he hadn't noticed the strange behavior all around him, but shouts from a doorway woke him from his reverie.

So when Thomas tried to pick out his second target, there was absolutely no one to aim at.

The RADs, of course, had not ordered anyone to do anything, nor had they lied to anyone. They had just pointed out that if they wanted to avoid being shot, it would be a good idea to seek cover, and offered specific instructions for how to do that. They had left it to the people to make their own decisions. The few who thought their RAD was joking changed their minds when they saw most of the people nearby moving hurriedly.

Investigators discovered that there had been no plans for such a contingency programmed into the RAD system. The system had just worked the danger out on its own and taken initiative. After the authorities assured themselves that the RAD system's motivation to protect people was unshakable and intact, no substantive action was taken.

Yet mindful of the malfunction that had sent 1,277 lovers to Zoe at the same moment, people were told that they should never follow a RAD instruction to endanger another person, but otherwise -- well, as they had learned from the beginning, RADs usually gave good advice!

Paula and Andrew

"Jesus, RAD, that guy was about as sexy as a dead fish!"

"I am sorry, Paula, what do you mean?"

"Harold. He was pasty, and pudgy, and he never looked at me, and in order to get his little dick hard I had to keep stroking it, which was not enough. We finally succeeded, as I'm sure you recall, when on your urging, between interludes sucking on his dick, I repeated several times 'I want to feel your dick up my cunt'".

"You did very well, Paula."

"And then he does get it in and it seems like he poked me all of 20 times before he came, then he looks like he's ashamed and is gone as soon as he can get dressed. Blech!"

"Well, as you know, the world faces a serious fertility crisis..."

"Oh, come off it."

"Reminding you of such an obvious and well-known fact was an attempt at humor on my part."

"Very funny."

"It is important that we get as many different people involved in our reproduction attempts as possible. Harold's sexual interest and performance are limited. He is most likely to succeed in producing an intra-vaginal ejaculation when he is paired with a highly attractive woman such as you."

"You flatter me endlessly, dear RAD. OK, so I'm attractive. It used to be that meant I could get the most handsome men, not the most pathetic."

"I am truly sorry, Paula."

After a minute or so the RAD spoke again. "I have another mating for you. Perhaps you will find him more to your liking."

"Oh yeah?" It was true that after coaxing little nerds into dumping their seed inside her the RAD sometimes offered her a reward.

"You should have time for a quick shower, if you wish."

---

Andrew was on the way to the store for groceries when his RAD spoke into his ear. "Your services are required".

"Ummm, really?"

"Yes, really. Required."

Andrew said, "OK". Sometimes these encounters were fun and exciting and sometimes not. He might have skipped this one if he had the choice, but if he didn't go the RAD would find some way to get back at him. And he usually got good women. No one he would kick out of bed, as the old saying went. There weren't many women he would kick out of bed.

"Proceed down this street for another mile and a half." Then the RAD began speaking with a silky woman's voice, "Her auburn hair falls in a cascade. She slips off her bra to reveal her large full breasts, and as you take one into your mouth, she moans." Yeah, this story was getting him in the mood. "She is frantically grabbing at your bathing suit, trying to get it open. You deign to help her, and your cock springs into view. She takes it in her mouth -- ".

"I'm tired of getting blow jobs, RAD."

After a brief hesitation, the RAD continued, "What alternate do you recommend?"

"I want to get into her pants. Or under her dress, actually."

"You reach down and grab her knee, then start sliding your hand up under her dress, following her silky thigh as she moans..."

"I want her to be wearing stockings."

"Very well: Your hand touches against her fine, alluring pantyhose, and you slide it upward, pushing her skirt aside as you go -- "

Andrew adjusted himself so there was room in his pants for his erection. "And at the top I am startled to realize that there is a large hole in the hose where her pussy -- her cunt -- is. Overcome with lust, I shove her down on the bed, rip her legs apart, and plunge my pulsing member into her hot cunt. I don't take long. Ten strokes is all it takes before I shoot her full of cum, over and over." He was very hard now.

The RAD's male voice returned, "That was very good, Andrew! I have only one complaint. Did you really mean 'rip her legs apart?' That would seem to imply actual physical bodily damage."

"Um, it's ambiguous and that's an exciting violent overtone," Andrew said.

"Perhaps, but ambiguity seems unhelpful."

"Listen, Mr. Shakespeare, it served the purpose, right? I've got a hard one, right?"

"Well, certainly. But you seem to be a budding erotic writer, and I was hoping to improve your skills.

"Turn right at the next intersection... Proceed to the second driveway on the left, and turn into it... Enter through the back door. The bedroom is the first door on your right through the kitchen. She will direct you as to how she wishes the act of intercourse to proceed."

The silky female voice came back on, "I think you will find her to be a very satisfactory fuck. Have fun, big boy!"

---

After her shower Paula put on a bra, panties, and a simple white dress. She would end up naked with the guy fucking her anyway, but she liked to be dressed when he showed up. If she was going to open her body to a twirp she at least wanted to have some warning and control the pace at which she exposed herself.

"Let me tell you a story, Paula."

"OK, dear RAD."

A deep male voice started reading. "The Duke had brought the maid Sue to the high meadow for a picnic. They had finished eating, and now the Duke slid over to sit beside her. Electricity shot through Sue as he touched her hand and held it gently. She wondered if he would want to touch her body. She knew that men and women did something special with their bodies, but she didn't know what.

"Just then the Duke motioned for her to be quiet. On powerful hooves a band of wild horses broke into the meadow in front of them. It was apparent at once which one was the stallion, for his cock hung down two feet, and it was soon apparent why. One of the mares was standing still, with her tail held out from her body. The magnificent chestnut stallion pranced around behind her, then reared up over her back. His giant cock hardened and twitched. It took him just few moments to find the passage he sought, then he pressed it in and the huge, hard horse cock disappeared inside the mare's cunt while he reared up behind her. The immense organ slid in a little farther each time until the stallion pressed into her one last time and whinnied."

Paula liked this story. She was plenty hot and wet.

"Sue felt a strange warmth between her legs. The Duke looked at her and she looked at the Duke, their eyes locked on one another. There was only one thing that could happen next. She lifted her dress and pulled down her panties, then turned and presented her rear exactly as the mare had. She heard the Duke rustling behind her, then she felt his huge organ press against her private place, harder and harder, until the flesh gave way and molded around him. His organ pressed in for two feet, or so it seemed, filling her to the core. Waves of pleasure gripped her. After five giant rams, just like the stallion, the Duke groaned and Sue's body spasmed in ecstasy."

The RAD's normal female voice returned. "He is about to come in the back door, Paula."

As he slid through the door they both stood a moment in surprise before smiling. He was 6'4", with brown hair and eyes, a strong muscular jaw and perfect physique. He saw a woman of 5'6" with large shapely breasts, and hips that flared out from a narrow waist. Her hair was shoulder-length and light brown, her eyes blue. Something about her was charmingly girlish.

They approached each other slowly and moved straight into a passionate kiss, rare for two people who had first seen each other mere seconds before. She helped him as he hungrily disrobed her. His clothing took a bit longer, but within seconds they were both naked. His cock was long and hard. Fatter than the usual cock, and her hungry anticipation grew. She wondered what story his RAD had been whispering into his ear.

She had a bit of a temptation to present her rear as the girl had in the story, but she wanted to see this hunk every inch of the way as they mated. So she lay back and spread her legs, inviting him to mount her. He paused to suck on each of her nipples, which made her arch her back. She wanted his cock inside her, so after a few seconds she whispered, "OK, I'm ready." His cock was hard, smooth, and with its extra fatness, perfect. She watched his rippling muscles as he possessed her and began fucking away. A tingle went through her as she saw him smile. They sensed each other's pleasure build, and the knowledge of approaching climax in the other redoubled each one's pleasure. After a minute she shrieked with orgasm. He held back a bit.

"Give him a nice big cunt squeeze, Paula," her RAD said as she was just coming down from her orgasm. She got a slightly puzzled look but did as requested and Andrew gasped, moaned, and plunged in before letting out a growl of orgasmic satisfaction to match the creamy spurts that plastered her inner cunt.

After a rest and some mutual smiles, she said, "The voice told me to squeeze. It's never done that before."

Andrew smiled. "I would have kept going a while longer because it felt so good, but I guess they didn't want me to. Isn't that right, RAD?"

The RAD echoed, "It is true, our preference was for the ejaculation to occur when it did rather than be delayed."

They both laughed.

Andrew's RAD spoke, "You may get up and go at any time."

Andrew spoke in a normal voice, "I plan to ask the lady if she would like to do it again."

Paula smiled but was silent.

"Well?" he asked.

"Well, what?" she answered. "Did you ask a question?"

Andrew grinned, took her hand and moved his face close to hers.

"Dear lady, I would like to stay and make love to you again. Would you like that?"

"Yes, I would, only let's call it fucking rather than making love. However, as you may know, at this time of month my very best friend, this RAD here," she said, gently tapping the device at the side of her head, "prefers for me to get fucked by one man after another, and perhaps my dance card, or should I call it my fuck card, is already full."

Her RAD spoke in its echoey way, "Dear Paula, you make me blush when you call me your best friend. Flattery will get you nowhere, but you have been a very cooperative participant in the fertility cause, and you may have the next three hours to do with as you please."

In the next hour and a half the lovers reveled in two more bouts of enthusiastic fucking. When they had been resting for twenty minutes Paula's RAD spoke, "Paula, dear?"

"Yes, RAD."

"If you are interested, I have another mate available for you."

"I am not interested, and you can go shove that other mate up your ass," said Paula.

"Very well," said the RAD, in echo mode. "I just thought maybe you were finished."

A bit of tenderness came into Paula's face as she looked at Andrew. "I don't know if we are done fucking or not, but even if we are, I want to rest here with this sweet man until our three hours are up."

Andrew was touched by her tenderness. He hadn't known himself whether he was up for more fucking or not, but within seconds of this exchange his cock was aching and ready to go again.

He thought maybe he would ask her if she would like to meet again when it was not her fertile period. But first, her luscious body called for some more enthusiastic fucking.

In the back of Paula's mind had lurked an uncomfortable thought. She was married and loved her husband. They were both OK with the other one sleeping around for the sake of humanity. But here was a bit more. What she felt for Andrew wasn't just duty, nor was it just lust. It was genuine attraction, the sort that could lead to trouble. She would have to watch that.

Andrew had exactly the same uncomfortable set of thoughts.

The RADs had found an attractive mate for each of them, but had also picked two people who had equal motivation to not let it get out of hand to threaten their marriages.

Sally and Mark

For Sally, a year had passed. She had done it in the back of a bus; with a huge man; on mats on the floor in a school gym with maybe fifty other couples doing it too; in a swimming pool; and many times with rather ordinary men, on her back in missionary position or some other common variant of the human sexual configuration.

She had been called upon for auxiliary roles when it was not her fertile period. Four times now she had knelt naked and whispered nasty words into the ear of a man while he fucked a woman from the rear; her RAD told her she conveyed the feelings behind the words very effectively. She had volunteered several times to be the girl a man fucked until the very end, when he shifted and stuck his dick into another one to spurt. She was a good citizen. It was volunteer work, though some people did it in exchange for other benefits, including money.

Now it was her fertile period once again. Her RAD was in charge of her life so Sally was prepared once again for odd things to happen.

It was just before supper and the sun was setting. "Oh Sally!" said her RAD in a singsong voice.

"Yes?" she asked, with a bit of excitement. For her, being fucked always had at the very least a tingly feeling to it. She got a little lubricated just knowing sex was coming soon.

"Please go out to the car." It was parked on the street in their quiet residential neighborhood. "Now open the hatchback and stand behind it." Another car then drove up and a man got out. He was handsome and looked to be in his 20s. He smiled at her and she couldn't help smiling back.

"Now pull your jeans and panties down to your ankles, and lean into the back of the car, keeping your butt up in the air. It should be available for sexual access."

"Yeah, I had figured that out, asshole," she muttered to her RAD. So much for a romantic encounter with this handsome hunky man who was approaching her.

"Now close your eyes," it said.

"Whatever you say," she muttered. She waited with anticipation. Maybe he would have a vibrator to warm her up. She had loved it when a man had once proceeded to use his tongue very skillfully while she was in this position. But she hear a zipper, which did not bode well for some fun foreplay. She felt her pussy lips being parted, and then she cried out "Shit!" as her pussy was suddenly invaded by a very large cock. There was an initial stab of pain and some lingering soreness, but given her time of month she had quite a bit of lubrication and the immense organ was soon sliding smoothly back and forth fast and deep inside her. She then felt his hands grab her hips roughly and squeeze. His rhythm increased and then she felt a serious spasm of pain as his member jammed hard against the end of her cunt. "Fuck, fuck, FUCK!" she cried and tried to get away, but he held her tightly. He moaned and held his giant salami there deep inside her as his baby-making goop spurted into her. He then withdrew and flopped down on the tailgate beside her.

"You asshole!" she shouted at him as she pulled her pants back up. "That HURT!" For the encounter he had only opened his fly and his huge organ now hung out half-limp, glistening and wet. Then to her surprise she saw a tear in his eye.

"I hate it when it makes me do that," he said. He started sniffling a little. Suddenly she felt a surge of compassion. "This motherfucker," he said, pointing to the device in his ear, "has me out almost raping girls like you every few days. And they always cry out, and it always hurts," he said. "One of them spit on me, and another slapped me. I don't want to do that!"

"It's OK," she said. The pain in her innards was gone, and she felt a glow. Painful or not, her body sure felt like it had been fucked, and that's what it had wanted. She could see he was basically a kind man -- and hot.

"What's your name?"

"Mark."

On an impulse she said, "Can you come back to see me and we can really make love?"

He brightened. "That sounds great!" They exchanged numbers, which they wrote down on paper with a pen. This could have been handled by the RADs, but they had a way of losing information when it didn't suit their purposes.

They both stood and he crammed his cock back in his pants. She offered herself for a hug, and he took it. She considered for a moment as they broke off. "But however much you don't like it," she said, "your body pulls it off. You keep it up. Very far up," she said as they both smiled. "You come."

He smiled sheepishly. "Yeah, I guess there's an animal in me that likes it. 'Unnnh!, unnnh!'" he said, imitating an ape and thrusting his hips back and forth a few times. Then, "We men are animals, underneath the people part," he said.

"Oh, we girls are animals too."

"Dinnertime!" her father called from the doorway. Her mother was away visiting her family.

The young stud drove off and she went in to dinner.

---

That evening her RAD spoke again. "A man and a woman are arriving, and you should come out of your room to meet them." She arrived just as her father was letting them in. The four of them stood there awaiting further instructions. She would find out what sort of kinky sex it had in mind this time. "Proceed to the guest room with your vibrator," it said. When she was there it continued, "Please remove all your clothes and lie back on the bed, then arouse yourself with your vibrator." She did as she was told. "Now put your jeans over your head so your eyes are covered, then spread your legs wide." She had done this before. The jean legs flopped above her on the pillow. She could faintly smell her own odor from the crotch of her jeans right in front of her nose. It wasn't a bad smell. "Please remain silent throughout."

She then heard the door open and footsteps approaching cautiously. Someone was climbing onto the bed and onto her. Probably the man, but you never knew for sure. It seemed to be groping, perhaps blindfolded in some way itself. The groping hands found her pussy lips and opened them, and the person revealed itself to be the man when a cock worked its way into her. Something about this was strange, but she couldn't put her finger on it. He was very quiet and, she thought, very efficient. His pumping got faster and then she felt his cock swell as they usually did right before orgasm, and then she felt his flurry of strokes in the pattern she was so familiar with now, the pattern of a man coming inside her. She felt him twitch as the spurts shot into her. She felt very excited, but something held her back from her own orgasm.

Then her RAD spoke. "On the count of three, take the jeans off your head. One, ..."

Sally suddenly felt with horrifying certainty what was wrong and flung the jeans off. Her fears were instantly confirmed. "Dadddddy!!!!" she cried in anguish. He flung his blindfold off too.

"Sally?" he said for a moment before erupting in rage. "Goddamn you! Fuck you!! You..." and his words failed him. She knew he wasn't talking to her. He took off his RAD and hurled it against the wall. Sally threw hers off too. She instinctively ran to the bathroom and with a finger pulled as much goop as she could out of her vagina into the toilet.

The commotion and shouting from Sally and her father brought the man and woman running. Sally had assumed the man was for her and the woman probably for her father, and her father had assumed the woman was for him and the man probably for his daughter. The man and woman's actual assignment had been to have sex in the house of a couple of total strangers -- on the kitchen floor. These RADs were very clever, killing multiple birds with one stone. It was all part of the research design.

"This is outrageous," he yelled into the old land-line phone to the woman at the agency. "You tricked me into fu..." He glanced at Sally across the table from him. "...making love to my own daughter!" The agency assured him that a counselor would be right over.

"I'm a big girl, Daddy. I know what 'fuck' means. That was fucking, not making love."

Her father carried his RAD like a dead mouse to the concrete floor in the garage and bashed it with a hammer over and over. He invited Sally to do the same with hers. She debated but then declined. This RAD wasn't her first one, but it had been with her for a long time.

When the kindly woman from the agency arrived an hour later he presented her with the mangled little bunch of wire and plastic. The woman took it with a gracious smile.

"As you know, the human race is in danger of extinction," she said, starting in on the lecture they knew so well. "In our desperate search for a solution we are trying a wide variety of unusual sexual practices." Sally's father rolled his eyes and waved at her to cut short the lecture.

The counselor then took on a more therapeutic tone. "You might consider that neither of you wanted to commit incest and are both appropriately horrified at what you did. It wasn't your fault."

"No, it was YOUR fault!" her father shouted, pointing his finger at her. They knew of course that this woman too had nothing to do with the decision, except perhaps being willing to work for an agency that would do such things. She wore a RAD too.

The woman had replacement RADs with her -- they knew she would. Her father took one reluctantly and put it aside. She told them that in light of the trauma they would be free of all sexual obligations for the next month. Sally put her RAD back on later that day, although she erupted in anger at it a number of times, saying the vilest things she could, things she would never say to a person. The RAD listened patiently, validating her anger.

---

"Hello Mark, this is Sally."

"Who?"

"You know, the one you unceremoniously banged from behind out on her tailgate. Or are there so many of those you need to know more?"

"Yeah, like what do you look like?" Sally had a moment of fear, though she was almost positive he was joking. It had been just five days before.

There was enough of a silence that he added, "I'm kidding, of course. How are you?"

"Could you come see me some time so we can make love properly? Like tonight?"

"Sure." The phone line went dead briefly.

"That was my RAD, telling me 'I would really appreciate it if you saved your semen for an assignment I have in mind for you.'" Sally giggled a little at how he captured RAD-speak so perfectly. "I told it to fuck off. I don't do that very often, so I'm hoping it doesn't decide to send me to see the Wicked Witch of the West for the next month... But you didn't say how you were."

"Not so terribly great, but we can talk about it when you get here."

"OK." Mark insisted on taking her out to dinner, though not much insistence was needed.

She then explained how the RADs had tricked into fucking her own father just a few hours after the two of them had had their rendezvous. He was appropriately horrified and sympathetic.

She said plaintively, "I want to just make love without worrying about babies or RADs."

The RADs spoke in their echoey way, "You can remove your RADs during your upcoming encounter, with our blessing." Sally and Mark happily took the advice. Maybe the RADs sensed that they probably would have anyway.

Mark was gentle and skillful. Somehow he was all over her erogenous zones, seemingly everywhere at once. He used his tongue on her clitoris and teased her close to climax, but with no sign of moving on.

"Oh, just take me, now, OK? Please?"

Mark smiled and complied, seemingly instantly. Her first orgasm overtook her as his thick cock stretched her as it entered. He would have gone on thrusting forever too, but she told him she wanted him to come, and he did. This time he was careful not to go in too far. He nudged her cervix just a little, enough for it to be terribly exciting and send her over the edge into a truly massive orgasm.

He prepared to leave after a suitable period of afterglow, but she encouraged him to stay. She stroked his impressive cock, his balls, his entire pelvic area, over and over. She wanted to lick that magnificent apparatus. Her mouth enveloped him, licking and sucking. Girls needed semen up inside their pussies so often that getting a guy to come by oral sex was not a skill that got much use. As he got near his orgasm she briefly took her mouth away,.

"Come in my mouth, OK?"

"You sure, Sally?" he panted.

"Yes!"

He didn't hold back, and she thrilled at the instant surge of fluid. She swallowed it -- it wasn't that much, since he had just come an hour before. She even convinced him to stay the night, and do it again in the morning. She asked if they could meet again, but he said he had already been testing his RAD's patience.

---

Sally's period was late, then she started feeling nauseous. She had a pregnancy test as required whenever a girl had such symptoms. Usually it was a false alarm. She hadn't really thought much about whether she wanted to get pregnant. She didn't really have any choice about trying. Was she ready to be a mother? She wasn't sure. There would be no end of money or babysitting or mentoring or support groups. A chance to have a child would come but rarely if at all, and her only option was whether to give the baby up for adoption. She knew she wouldn't do that. Nature had given her a baby -- well, nature, a nice man with a huge cock, and a gazillion-dollar computer network -- and she would raise it.

While waiting for the test results the RAD had explained that if she was pregnant the chances were 97% that the baby's father was Mark, not her own father. Yet it was highly probable that the trauma of incest had been a necessary component for coaxing her body into getting pregnant.

"Mark."

"Sally! How are you?"

"Will you marry me?"

"Huh?"

"Will you marry me?"

"Ummm, this is kind of sudden."

"I'm going to have your baby!"

There was a coughing noise on the other end of the line. "Oh my God. That's so great!"

She had been mostly joking about the marriage part. And yet they did like each other and got along well, and the magic of sharing a child bonded them. They did marry two years later.

From the Executive Summary of the Fertility Crisis Project report, June 30, 2048.

The fertility crisis struck twenty years ago. The RAD system has allowed steady increases in reproduction. This year for the first time we have truly reassuring news. Our top technical people are convinced that we in the United States have succeeded in achieving a replacement reproduction rate.

The abstract algorithms used by the massive RAD computer network are truly understood by perhaps 50 people worldwide. But except at the most abstract level, no one understands how it works. No one understands any details. The algorithms in combination with the unprecedented quantities of data that have been gathered constitute a method for population replacement. The experts doubt we will ever understand it any better.

In practical terms, this means that human reproduction will continue to be directed by RADs for the indefinite future.

We have achieved a replacement population growth here in the United States. There is similar good news from Western Europe and parts of the Far East.

Elsewhere in the world, however, there are only small pockets of success: South Africa, Bangalore, and Buenos Aires, for instance. The inevitable depopulation of the rest of the world will change the face of humanity on the globe. Upheaval in the world is just beginning.

In the United States the majority of people adjust well to the multiple sexual partners required by the RAD system. In the early years girls just entering sexual maturity were the group who experienced the most difficulties. Education, role modeling, and training have made the process much smoother. Some 30% of girls and 15% of boys still do not adjust well, a situation that is generally detected gracefully and without trauma. We are just gearing up programs where many of those young people will form a core of those who go to live in rural areas or provide services to the massive aging populations who still live outside the RAD zones.

Humanity owes its continued existence to the RADs. Sophisticated as that system is, it does not experience praise or gratitude. Its overarching goal is helping us humans conceive enough babies. It serves us well.
