A month before his first sex session with his 11-year-old daughter Lisa, Jim had seen an internet site that specialized in women having sex with mechanical machines fitted with rubber dildoes. The idea of women with machines excited him for some reason, and being pretty handy with tools decided to make a fuck machine himself, although at the time he had no real plans for the machine. Looking back, Jim had been watching his developing daughter for over a year and fantasized about sexually dominating little Lisa during that time, and now that she was in his control, he had a use for his fuck machine.

Knowing nobody would be home for a while, Jim left Lisa lying on the couch and retired to his workshop beside the house. He kept the door to the shop dead-bolted to keep out any nosy people, and to hide his newly finished fuck machine from his family. The machine he built was of the up-and-down variety, meaning it simulated intercourse with a realistic up and down motion. The machine was fully adjustable, with a drive range from two inches up to seven inches, and had a variable speed motor that could make the machine pump up and down from 15 times a minute all the way up to 150 times a minute. The machine also could be fitted with an almost infinite variety of dildoes to fit the session, and Jim had several rubber dongs in ascending size that he would soon use on his young daughter to fully stretch her anus.

Although Jim was now slightly concerned about the damage he must have done to Lisa's butt hole, he still felt determined to sexually mold her to his liking. He figured the first step in his plan would be to put an anal plug in her, thus having today's abuse work for him. So Jim opened up a padlocked drawer in his shop and found a medium sized plug for his little daughter. Jim locked up, left the shop and headed back for his sleeping daughter in the living room. When he arrived, she was lying in the same position he left her in, so he rolled Lisa onto her stomach bringing her butt toward him. The fifth grader still had her panties scrunched in her crack like a thong, exposing her pale butt cheeks to him. Jim sat for a second and admired her soft butt, rubbing his rough hands up and down her flesh, before pulling her panties out of her crack. Little Lisa's anus was red and looked well used; there was still a small amount of lube outlining the wrinkled hole, but Jim wanted to make this a little more comfortable for his daughter and used the lube he had previously put in the drawer beside the couch to grease up the butt plug. After putting a copious amount of lubricant on the plug he used his left hand to pull his young daughter's panties aside and spread her butt cheeks open, while holding the plug against her anus in his right hand. He then pushed the anal plug forward and it slowly sank into Lisa's butt hole until just the end knob held it from completely sinking into her rectum.

With the plug now in place, Jim fixed his little girl's panties to their original position and put on her denim shorts that had been lying on the floor. Then, with Lisa still out, he picked her up and took her up to her room, lying the schoolgirl on her back on the bed. Next, Jim took his daughter's cum-soaked shirt off, and for the first time saw his little girl's budding breasts. They were just bumps, the size of a lemon cut in half, with her tiny nipples topping the small mounds of flesh. Jim bent down and gave each of her little titties a kiss; they would be used in the future, then he pulled off Lisa's socks and shoes. Putting her socks and shirt in the clothes hamper, Jim noticed her school dress that was drenched in horse semen, and laughed at the absurd amount of cum the horse shot onto his little girl. Before leaving his daughter, Jim grabbed a wet wash cloth and cleaned off little Lisa's cum covered face and chest. Then he put her in a clean T-shirt and went downstairs to watch TV with her sleeping in bed now clothed, but still with the plug up her anus, loosening her anal ring for later abuse.

A few hours later, his wife returned from the doctor with his youngest daughter Jenny, who was 10 and wearing a pair of pink spandex shorts and a white tank top that barely covered her developing boobs. Even though Jenny was more than a year younger than her sister, they were the same height, and Jenny's body was more mature, with A cup sized titties, and a plump butt that always caught Jim's eye.

"Hi babe, how did everything go?" Jim said to his wife.

She replied, "Ok, he said my leg is healing better than expected and I should be out of the cast in a month or two."

"That's great," he said, then directing his attention to his young daughter Jenny, "And how is my little angel today?"

"I'm good daddy, where's Lisa?"

Jim answered, stroking her brunette ponytail, "Oh, she's upstairs sleeping, she helped me rotate some of the hay, and was beat when we finished. Why don't you give your dad a hug, I hardly get to see you any more."

It was true, Jenny was far more social than her older sister, and took part in ballet and tennis after school, not allowing her father much time with her.

"Of course daddy," Jenny said, hopping into his big arms.

Jim easily picked his little girl up off her feet, grasping a soft butt cheek in each hand and pulling her into his hairy chest. He often lightly fondled Jenny, slapping or pinching her soft butt every chance he could get, because she was accepting of his touches, never once questioning his intentions. He particularly liked it when she sat on his lap while watching TV or something, because her butt had much more flesh than Lisa's, and he could really grind his cock into her butt cheeks. Many times Jim's wife had almost caught him in this act with Jenny, but it was worth the risk for the wonderful orgasms he got while dry humping his naïve young daughter. One time, Jim had forgotten to wear underwear during the dry hump session with Jenny, and when he came, his semen soaked through his shorts and started to soak into Jenny's shorts before Jim realized what was going on. He immediately got her to her feet, whereupon he noticed a large wet splotch on the right cheek of her denim shorts. But Jenny never noticed the wet spot and never said anything to him, so it must not have soaked through to her skin; therefore he was safe and continued dry humping her, cumming at least once a week from the action.

When Jim was through fondling Jenny's spandex covered butt, he set her to the ground and watched her scamper into the bathroom, her ass cheeks rubbing against each other as she walked. Then he helped his wife get dinner ready. A little while later, little Lisa came into the kitchen, she was a little groggy like she had just woken from a full night's sleep.

Jim's wife said, "Hey hon', how are you doing? I heard you had a hard day's work and just zonked out afterwards."

Lisa glanced at her dad before answering, "Yeah, I was just a little tired."

"Why don't you sit down, dinner's almost ready," the wife said.

So little Lisa pulled out a chair at the dining table and slowly sat down in it, showing obvious discomfort.

"Are you ok baby, does your back hurt or something?" the wife said with concern.

Jim answered for her, "Yeah, she overdid it a little bit, I gave her a couple of aspirin earlier, she said it didn't feel too bad."

With her own physical ailments in mind, the wife showed more concern, "I don't know, baby do you think you need to see a doctor?"

Jim answered, "No way, she's tough, ain't that right sweet pea?"

The moment of truth came and passed as Lisa simply nodded her head and replied, "I'm fine mom."

The wife accepted it, "Okay sweetheart, tell me if it gets worse." Then she turned to Jim, "go ahead and put the food on the table, I'll go tell Jenny that dinner is ready," and she left the kitchen.

Jim quickly set the table and then talked to Lisa about the prior happenings, as well as to see if she still had the butt plug in her,

"That was very smart of you sweetie, you did good." He continued, now more quietly, "Did you find something in your butt hole when you woke up?"

She nodded her head yes.

"And where is that thing at now?"

Little Lisa didn't answer.

"Did you take it out?"

She didn't move.

"Is it still in your butt?"

Shaking slightly, she finally answered by nodding her head yes.

"That's good sweet pea. That thing is called an anal plug, and its going to stretch you out so that it doesn't hurt so much when you get your butt hole fucked. Soon, you'll actually like it. You understand?"

His daughter gave a slight nod; in the other room his wife and other daughter could be heard coming to the kitchen.

Jim whispered one last thing to Lisa, "After dinner I'm going to take you out to my shop and show you something, I think you'll like it. I love you babe," and kissed her on the forehead before sitting across from her at the table.

After dinner, Jenny started on the dishes, which gave time for Jim to take little Lisa to his shop and show her what he had planned for his little girl. She gingerly walked behind him, her anus now felt the pain, and deep inside, her guts burned in agony from the earlier anal pounding. Jim brought his daughter into his shop, dead-bolted the door, then set her down on a stool across from his covered machine, the rubber plug digging into her butt.

"Okay sweetie, what I'm about to show you is going to be your new toy. I made it just for you, and you're going to learn to love it."

The fifth grader just sat and whimpered, scared to think about what he was going to do to her.

"Here it is hon'," Jim said and pulled off the sheet that covered the machine. He had attached a gigantic ten-inch penis, that was much thicker than his own to the fuck machine, and little Lisa just stared in shock.

"You're going to have a lot of fun."

She said to herself, "Oh my God no! NO!"

Then Jim flipped the machine on, with its full drive selected at a rate of 80 thrusts per minute, the motor whirred as the giant cock pumped up and down.

The little girl sat petrified, then Jim turned the machine off,

"Don't worry sweetie, we won't use that dong first. You have to work up to it," Jim continued, holding up a five-inch long dildo that was fairly thin, "We'll use this one first, it isn't all that big, but the machine will be turned up so that it will pump into your butt very fast. You understand?"

Lisa was now so scared that she couldn't move a muscle.

Jim noted her state, "Listen babe, if you don't start answering me I'm going to put you on this machine right now, you hear me?"

Weakly she replied, "Yes, daddy."

"Ok then, I do want you do something right now though. I want you to sit on top of this machine and put this big dildo between your skinny little legs. Come on now, get a move on."

Lisa hesitantly stood up and tiptoed to the machine.

"Ok, now sit down on the padding with the dildo between your legs." She did as she was told and straddled the machine that was about the size and shape of a horse saddle, with the giant dildo now resting between her skinny thighs.

"Scoot up till the cock is pressing against your tummy," she obeyed him and moved forward a bit. "There we go, that's my little girl." Jim picked up his camera and took a few pictures of the scene. Little Lisa was sitting on the saddle shaped fuck machine, with her skinny legs on either side; the thick dong that was the size of her forearm was resting against her stomach.

Jim snapped a couple of pictures then spoke, "That's good baby, now why don't you pull your T-shirt off, I wanna see how far it will go up into you."

With that, the preteen slowly yanked her shirt off and tossed it to the ground, then positioned her half-naked body with her arms hanging at her sides. The enormous dildo pressed against her soft tummy, and it rose up a good three inches past her belly button. Lisa being only eleven and very small for her age, would have her insides wrecked if the dildo were ever used on her.

Jim did notice how obscenely large the dong looked compared to his little girl, that when he finally used it, the head of the dong would shove right into her bowels, but that excited him all that much more, because she would be one step closer to taking on a huge animal cock.

"Yes, that's good sweetie. Now give me a shot with your mouth around the head of the dildo."

"Daddy, I can't."

He rebutted, "You can and you will my little slut, now get your head down there," Jim finished, forcing his little girl to move back and bend her face onto the huge rubber cock.

Lisa bent down, her face hovering right above the cock for a second before opening her mouth, but then she complained, "I can't daddy! I just can't!"

Getting tired of her attitude, Jim moved behind his little girl and smacked her hard on her butt.

"Owie!" the little girl yelped in pain, both from his hand hitting her flesh and his hand bumping hard against the anal plug still inside her.

Lisa looked over her shoulder at her dad, who simply stood behind her with his hand ready to spank her again.

"Okay. Okay daddy, I'll do it," the schoolgirl said.

Jim came back around to her front and held the camera in place as she lowered her mouth to the giant cock head. The head was so large that Lisa had a hard time just opening her mouth wide enough to accompany it. She stretched her mouth open as far as she could and perched her lips on the tip of the dildo. Then she pushed her face down hard and the cock head started disappearing in her tiny mouth, her jaw stretched to the limit. The cock sank past her lips, and the ridges of the head were outlined on her hollowed cheeks. After a minute, Lisa stopped cramming the dong past her tightly stretched lips, the head of the monster completely filling her tiny mouth. Jim took a few pictures, then put his hand on the back of her head and gave a mandatory shove, trying to jam more of the dildo into his little daughter's mouth. But Lisa simply gagged, her throat not able to open enough for the rubber penis. Jim briefly thought about turning the machine on at that point, but realized she would probably choke on the fake cock. So Jim raised his hand up and Lisa quickly pulled her face off the cock, leaving a trail of spit linking her chin to the dong.

"Ok sweetheart, that's enough for now. You can go inside, but before you go we have to go over some things. I know you might want to tell some people about what happened today, but if you do, I'm telling you that now that I will give you the worst punishment I can think of. You can't tell anyone, even your sister. Now, you have to leave that butt plug in you for all of tonight, keep it in you when you go to sleep. If you take it out I'll punish you, and to insure that you don't take it out before you go to sleep I'm going to come up to your room and check at some point during the night, you hear me?"

She nodded yes.

"Ok, and I don't want you to wear your pajamas, wear one of my old shirts without any panties on so I don't have to wake you when I check tonight. Ok? So leave it in tonight, and I'll let you take it out before you go to school tomorrow."

"Ok daddy, I'll do what you say,"

"That's my good girl," Jim replied, "Now put on your shirt and go back inside sweetie."

Lisa put on her T-shirt and scampered out of the shop and into the house while Jim put the dildoes away and locked up his shop.

That night, Jim kept his promise and checked in on little Lisa at around 2 AM. She obeyed him and still had the plug embedded in her anus. He left her room, satisfied that his kiddy slut daughter would soon be ready for total domination.

When Lisa woke the next morning, she immediately went downstairs to find her dad, her mom was the only one in the house, and was in the kitchen.

"Mom, where's daddy?" little Lisa asked, urgently wanting to have the butt plug removed. She had a hard time falling asleep because of the discomfort, but now her butt didn't seem to hurt as much, just as well she didn't like it in her.

The mom replied, "Oh, I think he's outside sweetie, out in the stable."

Little Lisa took off quickly, and found Jim in the stud's stall from the previous day.

He noticed her right away, "Hey sugar, how ya' feeling?"

"Daddy, please take it out, you said you'd take it out now."

"Oh I will, just a minute now, what's the hurry?"

She replied, "I don't like it daddy, it doesn't feel good like you said."

"That's cuz' you got to give it time, this time next year you'll be begging for me to put something up that skinny butt of yours."

Then rubbing the back of the big stud, Jim said, "You remember this guy sweetie?"

She gave a small nod.

"You'll get to know him a lot better in the future."

Lisa stood motionless.

He spoke, "Alright then, bend over and grab your ankles for me."

Lisa did what he said and bent over, with her hands circling her ankles. Jim came up behind the preteen and raised the oversized shirt off her butt, revealing the knob of the plug embedded in her anus. Then Jim grasped the end of it and yanked it out in one motion, causing little Lisa to gasp out in shock and relief. Her tiny butt hole slowly began to close, but before it did Jim moved forward and shoved his whole tongue into her, happy that her muscles were already beginning to loosen up. Then he pulled his tongue out and swatted each of Lisa's pale butt cheeks with his hand,

"Ok, you're done, get on out of here."

Lisa immediately stood upright and ran into the house, feeling much better that the pressure inside her was now gone.

The next couple of days were pretty much the same for the little fifth grader, her dad would make her wear the butt plug eight hours a day, one time even to school, as well as get her anus tongue fucked whenever she was alone with him. One evening, the wife went out for something, and Jim sat at home with Jenny and little Lisa watching TV.

Wanting a little fun, Jim had Jenny climb into his lap while Lisa sat right next to them. His youngest daughter rested her back against his hairy belly as he fondled the preteen. Jenny of course was oblivious as Jim repeatedly ground his cock into the 10-year-old's plump butt cheeks, but Lisa sat totally silent and in total disgust at what she saw. Then, the show they were watching finished, and as luck would have it a football game was on, thus allowing Jim ample reason to move about while cheering for "his" team. When a team finally scored a touchdown, Jim humped upwards very hard, jamming his cock into his littlest girl's ass just as he exploded into orgasm. Lisa just sat next to them, disgusted, as her father's cock twitched between Jenny's butt cheeks and he pumped his cum into his underwear.

That Saturday, Jim decided it was finally time for little Lisa to get a ride on her new toy. He arranged it so that Jenny and the wife would go out shopping for Lisa, leaving him all alone for several hours with his kid slut.

Upon Jenny and her mom leaving, Jim went out to his shop and got the fuck machine all ready. He fitted the device with the 5-inch long dildo that he had shown Lisa, and clicked it on to make sure it would work properly,

"This is a thing of beauty," Jim said aloud to himself, then he turned on the switch to his two hidden video cameras; he would capture every moment of her sexual training on tape.

Next, he clicked the machine off, lubed up the dildo, and ran in to get his fuck toy.

"Sweet pea, its time. Did you go poop this morning."

She had and nodded her head yes.

"Okay then, let's go."

Lisa had been dreading this moment, and didn't cooperate lightly.

"Daddy, I can't! I feel sick to my tummy, can't we do it some other time?"

"Let me feel your head." She didn't have a temperature. "Well, your head isn't warm, so I'd say you've just got the butterflies. Which is normal to have when you're nervous about something. But that still doesn't change a thing, so get up right now before I have to tell you again."

"Daddy, please don't!"

Jim grabbed little Lisa and bent her down on her bed, her butt sticking up in the air,

"I will spank you, then I'll make you come with me, and I know you don't want that."

Defeated, Lisa reluctantly said ok and got to her feet to follow him into his shop.

When she got into his shop, her stomach was in knots, she hadn't had the butt plug in her since the day before, which Jim had planned so it would give her a rest before her punishment today. He immediately sat her down on a bench across from the machine and made her watch a demonstration,

"Like I said before, we're going to start off with this 5-inch cock, and if you're good I'll only use this one. First, I'm going to put it only a couple of inches up your butt, just to get you used to it, and turn it on real slow like this," He said as he clicked on the machine set for a 2-inch stroke at 20 per minute. To Lisa it still looked fast, but she liked that it was only going two inches into her, far less than her father's big dick. Kind of whimpering still, she said to herself, "That's not so bad, I can handle it."

Jim continued, "Ok, sweetie, now take all your clothes off except for your socks, and hop over here."

The fifth grader obeyed her father and undressed, her skinny body looking luscious to the old man. She didn't have a pubic hair on her, and her pale butt was just a handful for him. When she was naked she padded over to the machine and waited.

Jim said, "Well, what are you waiting for? Hop on top of it."

Lisa got onto the machine, and then sat down, her butt cheeks flattening onto the cold vinyl cushioning, she shivered at the sensation.

"Ok sweet pea, now I want you to scoot forward a little more and then bend toward me so that your butt is right over the hole for the dildo."

The little girl did as she was told and Jim moved the driveshaft, which brought the lubed dildo right up against her anus. She gasped at the coldness; it had been outside in the cold shed all night.

"Daddy, it's so cold!" Lisa said, her butt hole shrinking at the feel of the chilled rubber dong.

"Well sweetie, I guess you just have to live with it until you warm it up."

With that Jim bent Lisa forward a little more and then locked the machine in place so that only two and a half inches of the dildo would be inside her butt, with only two inches being pushed in and out.

Jim stepped back and made her begin "We're all set hon', now you have to shove the dildo up your butt for me to start the machine."

With apprehension the eleven-year-old lowered herself and nudged the tip past her sphincter, then quickly shoved the two and a half inches of the rubber cock up her butt hole. She didn't break a sweat getting the dong into her, but the chilly feeling the dildo brought into her bowels made her tense, tightening her anus.

"I'm ready daddy."

"Here goes," and Jim switched the machine on to 20 thrusts a minute. It slowly whirred into motion and the preteen immediately gasped from the shock of the cold rubber sliding in and out of her butt.

"Oh daddy! Oh God! Oh, oh God!" little Lisa groaned.

"That's a girl, loosen up, it'll start to feel good pretty soon."

Jim and his cameras watched as his little daughter straddled his fuck machine, which rhythmically drove two inches of the rubber cock into her anus. Compared to her father's brutal ass raping, this was a piece of cake for Lisa, but the comfort soon started to change.

"Ok sweet pea, I'm going to increase the speed a little bit, not much though, here goes," and Jim doubled the speed to the machine, now driving into the preteen at 40 thrusts per minute.

The machine immediately kicked in and Lisa gasped at the change, but held firm, her butt cheeks still resting on the vinyl seating. Little Lisa's butt hole was loosened quite a bit by the anal plug she was forced to wear, and so far she was holding her own with the fuck machine.

Jim asked, "How does that feel pumpkin?"

Flinching a little at the thrusts, she replied, "Ok, daddy, it doesn't, feel too, bad."

"Good, you seem to be enjoying yourself. Now I have something else to show you." And Jim reached into a cabinet and pulled out a 16-ounce jar full of a thick white liquid, moving it over to his daughter.

"Sweetie, you know what this is don't you?"

Distracted by the thrusting dildo, she couldn't really think, and shook her head no.

"Well Lisa, remember last week when you had that little adventure with that stud horse?"

Instantly she realized what it was. "Oh no! It can't be, how could he!"

"That's right, this is a jar full of horse semen. I got it from your stud this morning, this is how much he shot out in one orgasm, it's pretty impressive. Now here's what's going to happen. We're going to play a little game, if you lose you'll have to swallow a certain amount of this horsey cum."

Jim had thought of this game the night before while lying awake in bed. It was fixed so that at the end she would not be able to win no matter what she did.

The motor of the fuck machine continued to drone as Lisa's anus was repeatedly penetrated by the shallow thrusts; she sat still in shock, looking at the horse cum.

"Here's how the game works, each adjustment I make on the machine will take away a little bit of cum that you have to swallow, that is if you can handle the adjustment. So the further you go, the less horse goo you'll have to eat. Understand sweetheart?"

The preteen nodded yes, and the game began.

"Okay, first I'm going to increase the speed of the machine." With that, Jim vamped it up to 60 thrusts per minute. Lisa began groaning a little, but kept her cool as the dildo penetrated her butt hole more quickly. Then, she got a kink in her foot which was resting on the side of the machine and moved to adjust her position. At her movement the dildo popped out of her anus and repeatedly jabbed into her right butt cheek, shaking the flesh at each thrust.

Jim saw what happened and told her, "Well, sweetie that's your own fault, you got to get it back in you, I'm not turning it off. Or you can stop and eat the horse semen."

"No daddy, I can do it." Lisa said as she moved her puckered hole back into position. The rubber dong jabbed at her anus a few times then entered her and the schoolgirl sunk onto it again.

A minute later, Jim said, "Okay, sweet pea, you seem to be handling that ok. Now I'm going to lengthen the amount of dildo shoved into you." And Jim clicked the rod on the machine to increase the stroke to three inches, keeping the pace at 60 per minute.

Lisa had gotten used to the previous thrusting, but the new inch seemed like a whole new world, she gasped out as the cock shoved further into her.

"Oh daddy, it hurts! I don't know if I can handle it," the little girl whined.

"Do you wanna quit?"

The little girl answered, "Owie, owie, nah, nah, no, I can, I can, I can do, it."

A minute later, Jim asked his daughter, "Well sweetie, I'm going to increase the speed. You can stop now if you'd like, but you'd have to eat an awful lot of the horse semen. What do you say?"

In her little girl voice, "Go ahead, ow, daddy, I can, handle it, owie."

So, he increased the speed of thrusting to 80 per minute. Right away Lisa cried out, "Owie, owie, owie! It hurts daddy! Daddy, daddy, it, owie, it hurts!" Three and a half inches of the dildo penetrating the 11-year-old girl's anus over and over and over again.

Then, Jim noticed that Lisa had raised her butt up a little bit, so that the full length of the cock didn't stroke into her. He cured this by placing his big hands on her thin shoulders and forcefully shoving her down until her butt cheeks smashed against the seat of the machine, squishing on the vinyl.

"Ouch daddy!"

"Then don't try and cheat, you little kiddy slut. You'll get what's coming to you. If I see you trying that again it's over, you hear?"

In a sad tone, Lisa answered, "Yes daddy." The whole time, the dildo continuously driving into her abused anus, and the little girl responding with random gasps.

Without saying anything, Jim made two adjustments to the machine, lengthening the stroke to four inches and speeding it up to 120 per minute. Instantly, the machine kicked into high gear and punched into Lisa's bowels; she immediately yelped and jumped up, pulling her butt off of the machine. Lisa crouched above the machine, as the dildo below her rapidly pumped up and down.

Jim said, "You know the rules Lisa, you have to get it back in you all by yourself, or you forfeit and have to drink the cum."

"How much will I have to drink?"

He answered, "From your previous experiences, it would be too much for you too handle. So you better get that dildo in you right now!"

She of course whined, "Daddy, I can't. Why, why are you doing this to me?" And she broke down a little bit, about ready to cry. So, Jim gave her a quick slap on her ass to bring her back to reality.

"Listen sweetie, there are two choices. You can get that dildo back up your butt hole, or you can swallow this jar of horse semen, either way I'll be happy. Now which will it be?"

After a second, little Lisa wiped the oncoming tears from her eyes and positioned herself back over the dildo. The eleven-year-old mustered up her strength and crouched a little more, ready for her anus to receive more abuse. The tip of the dildo tapped against her left butt cheek a couple of times and she lifted up and moved over a bit. This time she was too far right when she came down, and the rubber cock jabbed hard into her butt cheek several times, making a dimple in her pale flesh and causing the fat she did have on her butt to jump repeatedly. Thinking of a new approach, she moved up again and reached down with her hands to grip her butt cheeks and spread them apart, exposing her anus.

"That's a good girl, use what you've learned. Good girl!" Jim applauded her.

But as she began to crouch down her footing slipped and she fell onto the vinyl, her butt cheeks slapping hard against the padded seat; the dildo missing her anus and jabbing her in the cleft of her butt flesh. Lisa sat for a few seconds as the rubber dong repeatedly rubbed along the outside of her asshole, then she got up and tried again. This time she succeeded, and with her hands holding her butt cheeks apart, the rubber cock tapped right against her anus and she slowly lowered herself.

"Ouch, ow, owie, owie! Daddy, ow daddy!" Lisa wailed, letting the dildo further penetrate her rectum until her butt was again resting on the vinyl seat of the machine, the cock hurriedly fucking into the fifth grade girl's tight ass.

"Good girl, how does that feel sweetie?"

"Ouch, daddy! Owie, ow, ow, daddy, owie, it, hurts!" was all little Lisa could say.

"Well, sweetheart, you still have more to take up your butt, so I'm going to adjust it now."

He neared the machine as Lisa cried out due to the agony of the thrusting dildo. Something in Jim made him not able to believe what he was seeing. His little fifth grade daughter in blonde pigtails, her naked, pale body weighing seventy pounds at the most, with her bony butt cheeks sitting on a machine that was fucking a rubber dildo four inches into her asshole. His cock was fully erect, and seconds away from blowing, so instead of adjusting the machine now, he approached little Lisa and pulled his pants and underwear down in one motion, his cock bobbing right in front of the preteen.

"Now sweetie, I'm going to cum on your cute little titties, you hear? I won't cum in your mouth so don't worry."

"Owie, ow, okay, daddy! Ow, ow, ow." Lisa yelped, the dildo swiftly jamming deep in her butt.

With that, Jim moved forward and shoved his cock right into his little girl's mouth. Lisa immediately tried to back away, but Jim grabbed at the back of her head and held her in place. Then Jim slowly began pushing his thick cock to the back of his daughter's mouth. Lisa was still gasping from the dildo, and now with her mouth filled with cock, her cries were muffled. At this point, Jim had no remorse for his daughter and pushed himself inside her till his cock head jabbed against the entrance to her throat. Lisa flinched and gagged, but of course couldn't move away with his hands still holding her head. Jim now had half of his eight-inch cock in her mouth, but he wanted more; Little Lisa felt his hands tighten in her hair and his arms flex, ready to ram his cock into her face. Then the head of his cock entered her throat, but he did not ease off any pressure, instead Jim pushed harder with his hands on the back of her head. The preteen flipped out, with the dildo still rapidly prodding her butt hole, and her father fucking her face.

Lisa thought, "He's gonna KILL ME... Please God!"

Jim grunted, "Yeah, take it baby, I'm gonna give you all of my cock!"

She felt more of his cock slowly slipping past her lips, over her tongue, and into her tight throat. And down it went. Lisa's throat bulged out as her dad shoved his cock all the way into the small girl's face. The next thing Lisa knew his soft testicles were pushed onto her chin, one on either side, and his rough pubic hair was pressed onto her nose. Jim held his cock head deep in his daughter's throat, who was now getting fucked from both sides.

"Yeah sweetie, that feels really good. Swallow a couple times for me. Yeah, milk my cock with your throat."

Even though Jim wouldn't have cared, in actuality, Lisa was gagging on his cock, which stimulated him very much.

After holding his balls against her chin for a few seconds, Jim slowly eased his cock out of the little girl's throat. When only the head remained in her mouth he made his daughter suck his cock like a Popsicle for a minute. Then he quickly yanked his cock from her mouth just in time for his cum to spray all over the preteen's naked chest. His warm load shot all over Lisa's tiny titties, and oozed down her chest and stomach where it stopped at the top of her skinny thighs. Jim's orgasm lasted a while, and he coated his little girl's front with his thick semen; with his last shot he pointed his cock right at Lisa's face and squirted a clump of cum that landed on her forehead and dripped down to her nose. Lisa didn't like her dad's cum shots very much, because it reminded her of the horse that had came all over her, and when her dad shot the load on her face she immediately cringed and wiped the sperm from her face, leaving her hand sticky with the goo. Meanwhile, Jim used his still hard cock to spread his cum all over the preteen's chest, taking time to rub his cock into her tiny, soft titties.

After catching her breath and with the dildo still pumping into her butt, Lisa cried out, "Owie, you said you wouldn't, ow, do that!"

Still rubbing his cock on her semen coated chest he replied, "Mmm. No I didn't, I said I wouldn't cum in your mouth, and I didn't. That was so nice sweet pea. But now it's time to move on."

Next, He increased the fuck machine's drive to the max for the dildo, five inches, and the speed up to 150 per minute. The motor made a quick buzz sound then kicked into its fastest mode. Right away feeling the onslaught, Lisa tried to jump off the machine, but her father was right there to stop her. He pinned her to the fuck machine by grabbing onto her shoulders and holding her down, forcing her butt to squish on the seat.

"OWWWWWWWWIIIEEE!" Lisa screamed as the thrusting rubber cock repeatedly raped her asshole.

Jim simply held her butt down on the seat, his now limp cock resting against her chest.

"Ok pumpkin, here's the end of the game, I will hold you on this fuck machine as long as there's cum left in that jar." Jim said and nodded toward the full jar of horse cum on the bench next to them.

"OWIE! DADDY! IT HURTS!"

"I know it does baby, that why I'm offering a way for you to stop it, you have to swallow all the horse semen in that jar. Then I'll let you go."

Lisa did nothing except cry out for a second, the 5-inch dildo fully penetrating her asshole more than twice a second!

"Sweetie, do it now! This is your only choice. If I were really mean, I would tie you down to this machine and let it fuck into your butt for hours."

Something must have clicked in little Lisa's head, or maybe just out of sheer terror, she reached over and grabbed the jar full of horse semen, which was still warm in her tiny hands. After a few more cries of agony, she held the glass of thick cum up to her lips and breathed in the smell. The bitter smell alone almost made her throw up. But she had no choice; the dildo was torturing her butt hole!

She occasionally gasped in pain "Ow, ow, ow! Ow, Owie! Owie!"

Her father said, "Drink it now!"

With that, the 11-year-old, scared out of her mind, opened her lips and took in a mouthful of horse semen. She cringed at the sour taste, and almost gagged.

Her father yelled at her, "Now swallow it! There's a lot more!"

Jim was right, Lisa had trouble with a mouthful of the cum, but there was at least a dozen more mouthfuls left.

Finally, Lisa brought her remaining strength together and swallowed the mouthful of sour horse semen. The cum was very thick, and it oozed down her throat, coating it with goo, and not really going all the way down. Lisa coughed a few times, so that she wouldn't throw up, and went for a second mouthful. Her lips open, she poured a few large clumps of the sour horse cum into her mouth and quickly swallowed it, the thickness of the cream still getting stuck halfway down her throat.

Her father, holding her shoulders down, praised her as the dildo still slammed into her anus at a hurried pace, "Good girl! That's my good girl! Go ahead and drink the rest now."

With over three-quarters left, the fifth grader brought the jar of horse semen to her mouth and this time opened her lips and started to drink the cum just like a thick milkshake, downing mouthfuls at a time. Little by little the thick sperm disappeared into the little girl's belly, which now felt warm and gooey. Incidentally, the motion of the dildo shoving up her asshole made the feeling of the sperm in her gut very weird; shaking it around and constantly reminding her what it is that she was drinking. With a little bit of horse semen left, the preteen stopped and took a few breaths. The thick white goo still coated the roof of her mouth and her tongue, and the sour taste of the cum was very strong in her mouth. Then little Lisa continued and took in a last mouthful of cum, her cheeks bulged with the warm goo. Finally she swallowed, and the last remains of the thick horse semen oozed down her throat, where it helped fill her belly.

Immediately Jim took the jar from his little girl and set it aside, then grabbed her under the armpits and hoisted her off of the fuck machine freeing her anus from the torture. To her credit, Lisa made it that far without passing out, but once the dildo was pulled out of her asshole she was lights out and collapsed in her dad's arms.

He hugged and kissed her and carried her naked body into the house and up to her bedroom, where he placed her in an oversized shirt and set his little girl on her stomach on her bed. Jim knelt down and gingerly licked at her abused anus. She had her wrinkled hole fucked for over an hour and it was still gaping from the dildo.

"You are my sweet little kiddy whore, I love you so much." And with that shoved his whole tongue up his fifth grade daughter's asshole. Then he pulled it out, gave her a kiss on each butt cheek and slipped out the door, ready to think of more training for his kid slut daughter.
