The twins, blonde, blue-eyed round faced, lay with their backs on pillows against the headboard of the king-sized bed, watching the explicit video. They had been like this for the last forty-five minutes, their parents in the office next door with one of the sanatorium doctors. They were clothed in gowns, white socks, and disposable slippers, and both stared in wide-eyed amazement as two boys had sex with each other. Melissa, almost twelve, felt the wetness between her legs, just as it had been when the nurses had undressed them in the examination room, both being able to see one another's naked body. The nurses had used rubber gloves and poked up their arse holes, which, Melissa remembered, made Bob's dick grow and stretch and get really hard, and when one had begun to poke in her "private place" she began to get wet, just as she was wet now, watching one boy stroking and playing with the other's dick. Bob's dick had been poking straight and stiff under his gown almost from the start of the examination, eyeing the nurses, who were almost as naked as them. Boy and girl were blushing as the examination went on, until the nurses dressed them as they were now.

Melissa squirmed a little, feeling the wetness between her legs, she tried closing her thighs and keeping them closed, but finally she spread them a little and began to massage the area because it was getting to her, as if it were an itch. "Unh ..." she suddenly moaned.

"What?" Bob asked, looking down as she stroked her cunt, embarrassed that he was sitting here beside his sister with a hard on he didn't know how to stifle.

"Oh, that feels a lot better," Melissa told him. She watched the screen, the boy's were kissing as they both stroked each other's pecker's, her hand needed a better grip and she pulled the hem of her gown up to show her pussy to herself and her brother. She touched the wet lips and sighed, groaned as her brother looked at her, bemused.

"What?" he repeated.

"Oh, Bobby," she sighed, "that is such a good feeling. Rubbing myself there, like."

"Can I feel it?"

"If you let me do to you what he's doing to that boy," she told him. "Let me see your thing. Let me play with it, like they are." She didn't wait for Bob to do it but jerked the hem of his gown off his prick, hard and stiff at it's full length. She put his hand on her dripping crotch, then turned herself about so she was facing his pecker. "Rub me. It feels really good."

Bob was nervous, but he lightly rubbed Melissa between the lips of her cunt and when she moaned again, and knew she liked it, rubbed a little harder, and began to explore it a little more. He stopped for a moment after she had rubbed his dick up and down a few times, then had to stop altogether as an incredible feeling went from between his legs, at his crotch, and overwhelmed him. He spurted a load of warm, thick liquid, then another, and groaned as he felt release overwhelm him. It shot up and landed all over Melissa's face, in her hair, and on her hand.

"Oh wow!" Melissa squealed, looking at his dick, utterly amazed by it, then looked at the goo on her hand and wiped some of it off her face. She licked it. "Uhm. Mmmmm." She licked the rest from her hand, then stuck out her tongue and licked the dribbles from his dick.

"Wh-what are you doooing?" Bob sighed heavily. He looked at Melissa's twat, and slipped a finger gently between her lips and pushed it as far as it would go.

"Oh, Bobby!" Melissa yelped, and her hips jerked toward his face. Bob slipped another finger into her pussy and she jumped again, "Ahhhhh!"

"Do you want me to stop?" he asked naively.

"Oh, gawd, don't you dare," she ordered him. "Try licking me there."

Bob made a moue with his lips, but put his head down and kissed her pussy, who's lips quivered. He stuck out his tongue and licked the lips, then went further with it, pushing it in the same way he had done with his fingers.

"Oh gawd, oh gawd, oh gawd!!!!" Melissa felt her whole body shudder and jerk, and she yelped as she experienced her first orgasm. "Oh, Bobby, oh geez, it's ... it's ... oh gawd, it's happening again ..."

"Look at them," The twin's grandmother told the doctor and their parents, as all of them watched them on the large video screen in the doctor's office, "Melissa just loves it, and Bob doesn't know what to think." She laughed, watching them on the screen, her own juices running madly between her thighs onto the cushion she sat on.

"Should we rape them now?" their mother asked. She was half naked, her skirt on the floor while the Twin's father worked his fingers between her cunt lips and she breathed heavily.

"God yes." Their grandmother was only forty-five, and had given birth to their mother when she was thirteen, a one time patient here, in the sanatorium. "I want that untried cock in my cunt right now. She stripped completely and made for the connecting door between the office and bedroom the twin's occupied.

Grandmother, father, mother, doctor came through the door, one at a time, private parts exposed, dripping in anticipation, with lustful needs to satisfy. The children ignored them. By this time, Melissa had discarded her gown, now in a ragged lump on the floor. Bob's cock was hard again as they french kissed and Melissa's hand played between his legs, massaging his tiny, untried balls. Melissa pulled Bob on top of her, taking his virginal prick and aiming it at her cunt. "Put it in me, Bob," she ordered. "I don't ..."

"It'll be alright," Melissa encouraged. To Bob, she seemed to know a lot more than he did.

"And what's going on here, now?" a voice asked. The kids froze. Bob's cock still in Melissa's hand, his body arching over her own. "Are you two going to fuck?"

"N-nanna?!" Bob blushed and rolled away from Melissa, pushing himself to the other side of the bed, away from her, "We-we were just watching the T-TV." It was plain what was happening on the screen in front of everyone. The scene had switched from two boys to a boy and a woman in the throes of fucking.

"We thought we were allowed to ..." Melissa began to say, then realized that she was naked and tried to cover her private parts. It took a little while, her parents and grandmother, and the doctor standing there, her grandmother and mother were just as naked as she was, and her father was slipping quickly out of his pants with an enormous prick staring straight at her, hard and ready for a good going over in her cunny. She pulled her hands away from her crotch and presented it to them. "Daddy, do you want to play with my'baby hole'?" Her grandmother and mother had told her that was where baby's came from and that she might be getting a baby of her own soon. But they had not said anything more, even though, while baby sitting, her grandmother sometimes put a finger there and rubbed in it and gave her that wonderful feeling she'd just had from Bob's own fingers.

They came to the bed, the twin's grandmother going around the other side to Bob, her parents sitting, both of them completely unclothed now, next to her. Her father leaned in and began to french kiss her, he put her hand on his organ, eight full inches of thick rod, and showed her how to pump on it. Her mother parted her legs and slipped two fingers up and into her cunt, then laid her thumb over the bump above it and began to rub it and make it grow and get hard, just like her father's prick, or even Bob's.

Bob's cock grew quickly, even as he blushed to have his grandmother mount him and and start kissing him. But he relaxed gradually, and soon he felt his prick straining to rise from under her arse. "Nanna?"

"What, sweetie?"

"You're sitting on my ... on my ..."

"On your prick. Well, let's put it where it'll be of some use." She pulled her hips up and Bob's cock sprang to attention, grazing her cunt lips. "Oh, that tickles," she told him. Then she grabbed the half length cock, pressed it against her cunny, and rammed herself onto it.

"Ahhhhhh!!" Bob groaned, "What are you doing?!"

"We're fucking, Bobby, sweetie," Nanna told him, "you have no idea how long I've wanted to do this."

She rode him for a few strokes, then told him, "Pump your hips up and down." He pushed up and down, and her slickened cave of lust responded with a squeeze of his rod as she pushed down on him. She felt his cream hit hard against the insides of her pussy, then again, then again, listening to him groan as he came and punched his hips in the air. "Nanna, oh gawd, Nanna," Bob groaned, "that was fantastic."

"Kiss me you little love machine," and forced her lips against his. She realized after a while that he was still hard and stiff, that his prick hadn't shrunk as it should have. "Wanna go again, Bob?"

"You bet."

"Alright, but this time, get on top of me and push your pecker in and pump real fast and hard. Can you do that?"

"I think so." They switched positions, and then Bob had his prick up against her soaking wet lust hole. He glanced at his sister. His father was pumping his cock into Melissa who writhed and flopped and wriggled like a tormented fish, but with a huge smile on her face and her eyes almost popping out of her head.

"Daaaaddeeeeeeeee!!" Melissa squealed as she came for the second time with his prick fucking her hard and fast. She gripped the post's of the bed's headboard as he rammed down and she thrust up with all her strength. "Oh do it, do it, do it," she chanted as each of his strokes plowed inside her. She found she could flex her cunt muscles, squeezing the length of his pecker, and make him groan loudly.

"Fuck the little whore, Charles, fuck her good," Melissa's mother encouraged as she sat beside Melissa, playing with her hard and stiffened nipples. She got Melissa to screech as she pinched her. And then Melissa's father was groaning and ramming his prick hard into her as she felt his goo explode from his prick. She arched her back and he forced himself deeper inside her.

"Oh I feel it, Daddy, I feel your goo shooting in me!" She pushed up against him twice more, then both collapsed in exhaustion.

Next to father and daughter, Nanna and grandson were collapsing after their second go around, this time, Bob's boy-sized organ shrivelling in his grandmother's cunt as they both gasped for breath.

Bob was fascinated by Nanna's tits, still firm and round, even at her age, and he squeezed them gently, then licked it's nipple in a tentative taste. Nanna sighed loudly, moaned, shivered under him.

"Lick it if you like, sweetie," she told him. She relaxed and he kissed the bulbous organ's nipple, sucked on it and made her groan in need. Bob sucked and licked leisurely, wondering at why and how his grandmother could be so overwhelmed with feelings and moans and groans. Melissa saw what he was doing and joined him on Nanna's other breast, licking quickly and drawing Nanna off so that her back arched, her hips threw themselves out and she was cumming again as the twins worked their magic on her.

Melissa lay on her back, a long thick vibrator pushed all the way up and buzzing in her pussy, her mouth sucking the woman's tit. The vibrator's other end was in the woman's own pussy and she was fucking Melissa with slow, gentle strokes, as her hands caressed the child's perfectly smooth, white body. The woman was only about twenty-five, big-boned, and rather homely. But what Melissa discovered was that the young woman gave real breast milk, and so she sucked greedily on the teat as she let the girl use her as she pleased; after all, she was paying for the privilege.

"Squeeze the tit," the young woman ordered. "Ahhhhhh, that's it."

Melissa found that squeezing the woman's teat sent a stream of milk down her throat. She licked the teat clean, then squeezed again. A little while later, she felt the young shudder as she came and forced her hips down on to Melissa and drove the vibrator even deeper inside her, making her have a new series of orgasms of her own. When they had settled down, the young woman held Melissa and kissed her mouth, her neck, and then her chest as Melissa relaxed under her ministrations.

The guilt of allowing a complete stranger to do what they wanted with her naked, hands on her nipples, on her pussy, fucking her, or sucking her pussy, even letting women do what they wanted, was slowly giving way to the pleasure she was getting from it. The embarrassment of being peed on was giving way to enjoyment, especially when she was the one doing the peeing. The only thing she didn't like was having to wear diapers, and a hood over her head, then be shackled to the bed, Bob beside her in the same way, at bed time. In the morning the smell of piss and shit was horrible. Bob still grumbled when they gave him a suppository that would work overnight and have him wallowing in shit in the morning. Chained to each other in bed during the night, the hoods blacking everything out, they were scared of what would come next.

The woman's time with Melissa was at end when the nurse came in and ushered her out. "You can play with yourself while you wait, Melissa," the nurse told her before they left. She lay in bed, fingering her clitty and working herself up to an orgasm, while wondering who she would be used by next. She loved it when her mother licked between her legs, when her grandfather's cock rammed her arse hole, as he did with Bob. When they finally got home, she would definitely make room for any cock that wanted to try her arse.

When the nurse returned she was accompanied by her mother and had a set of leather restraints and a hood. Melissa wasn't pleased but lay there as her mother came to her and kissed her, rubbing her dripping pussy at the same time. "Time for something different, sweetie," her mother told her, taking a set of wrist cuffs, and without questioning whether it was what Melissa wanted, began to put them on, chaining both wrists to one another. She did the same to her feet, and lastly, while the nurse held her head straight and immobile, she pulled a hood whose only opening was a flap for the mouth and holes under the nose so she could breath. Otherwise, Melissa was unable to see because the hood had no eye holes.

After a while, being carried, she smelled and heard the echoing of barking dogs in a room. Melissa was laid out on a new bed, her ankles were uncuffed, only to have her legs pulled up and spread wide, exposing her sex, and shackled to poles on either side of her. After a minute or two, she felt a rough tongue lick between her legs, and almost automatically, she relaxed and her pussy began to moisten and become creamy in anticipation. The tongue licking her was fairly rough, though, and she heard a strange panting noise. The licking continued, and then a something cold was pressed to her pussy and she jerked. Then she felt the head of a prick being set against her pussy, and a little canine whine as it was forced inside. Then, realizing that could feel fur against her body, she wriggled and contorted, trying to get away from the dog as it raped her, but the dog kept ramming her good and hard, and her contortions only served to act like her hips were pushing and massaging the big boner to make it ever harder, longer.

Melissa's screams were muffled by the gag, though she kept it up as the dog forced his prick into her, and after a few minutes, Melissa's body betrayed her mind and sychronized it's hips and cunny movements to those of the dog's big prick. She realized she was orgasming, and that she had been doing it for the last two minutes, almost non-stop. Finally, she felt the dog's cock drive home, pause, and then she was being filled with doggie goo, spurt, after spurt, it panted, whined with satisfaction, but it's dick stayed where it was for along time, and Melissa thought he would start fucking her again. Then, slowly, it started to go soft, and soon it was drooping and falling out of her.

The second dog they brought to her found it easier to get Melissa aroused, her pussy dripping with juices as his tongue licked them up. And though Melissa tried to protest and keep his doggie dick from entering her pussy, she relented after only a twitch of her cunt in displeasure. He fucked her more easily than the first dog, and she screamed joyously when he shot what seemed as a load that would never end into her slick hole. Two more dogs found her sychronize to them immediately. Though she protested when the gag was removed and a large canine prick offered to her to suck. She had it forced down her through, regardless, and learned to take the monster and like it. Six or seven dogs fucked her, and the same number shoved their cocks into her mouth. When she was returned to her room, her mother removed the hood, but the nurse placed a spring gag into her mouth that popped open and stretched her mouth so she could speak.

"There, something new, Melissa," her mother finally commented before she left. "I had to go through the same thing when I was your age. And now, Daddy and I are going to let you choose a dog for your very own before we go home. But you'll have to fuck it just to see how you do with it's dick, hm." She left, the nurse turned out the light and Melissa, still bound hand and foot, found herself embarrassed, humiliated, completely out of it, as her tears slid down her face and she turned to vomit all over one shoulder.
