Dirty Little Pig
by Medai

Susan Carpentar had grown up on the farm an only child. Her parents Tom and Ellen had always doted on her, giving her everything they could, but she being the only one she was always expected to help out with farm chores. She did so selflessly, always doing her part and taking on more and more as she grew older. Life on the farm kept her so busy that she didn’t spend much time with school friends or doing extra-curricular activities. By the time she was fifteen, she had still never had a boyfriend, had in fact never really thought about sex.

Her body was in puberty though and hormones were surging through her veins. Sometimes she would wake up with her panties damp, slightly out of breath, but she thought nothing of it. Susan was very pretty, stick-thin, flat-chested, without much in the way of hips, but a vivacious mischievous smile and beautiful green eyes. She enjoyed working on the farm very much and often took her time making sure her chores were done to perfection.

This helped Tom and Ellen immensely, particularly as they relegated more and more daily work to Susan while they focused their efforts elsewhere. Tom had a Bachelor’s in Agricultural science and a Master’s in Genetics. He spent a good deal of his time trying to find ways to augment the growth rate of his livestock, design a new feed or new drug that would make them more resistant to disease or more tender in taste.

One day in early summer Susan was in one of the barns, pouring food and water into the appropriate troughs, when she noticed something. She stopped by the pig stall as one of the male pigs was mounting a sow. She squealed as his weight held her down and his huge cock penetrated her from behind. Susan stopped, watching transfixed. She had never seen anything like it. She didn’t even realize that her hand had slipped into her jean shorts and was furiously rubbing her pussy. She was rubbing herself faster and faster, moaning as she watched the sow get fucked. She started moaning, urging them on, wanting to cum with them, when they did.

She collapsed onto a bail of hay, working her pussy as she watched the pigs fuck. She was getting very close when she was suddenly interrupted.

“What the hell are you doing?”

Susan turned to see her father standing at the entrance to the barn watching her horrified. Susan pulled her hand out of her shorts immediately.

“Daddy!” she exclaimed, totally off guard.

“What the hell are you doing” he repeated.

“Nuh. . nothing Daddy.”

Tom walked over, looking into the pen as the male pig shot into the sow. Susan noticed it too, her body trembling suddenly, so close to the orgasm it was denied. Tom looked back at her, noticing her reaction.

“You were watching the pigs,” he realized with disgust.

“No Daddy! I’m sorry!”

“What is the matter with you? You . . you’re disgusting.”

“I didn’t mean to!” she objected.

“This is what you like? Watching pigs?”

“I didn’t mean to! Daddy, I’m sorry!”

He walked away, deeper into the barn, but Susan knew better than to leave. She waited, fearing that her punishment was only being delayed while he processed the shock. A few minutes later Tom came back. He was holding a syringe.

“Daddy, I’m really sorry,” she said, fearful at what he was holding.

“You’re not my daughter,” he stated coldly.

“Daddy, I’ll never do it again. I promise.”

“You’re just a dirty little whore. You like pigs Susan?” He came closer to her, grabbing her arm. She struggled, screeching. “You’re going to love this then.”

He jabbed the syringe into her arm. She screamed, but he held her down, emptying its contents into the muscle. When it was empty, he pulled the syringe back out, stepping back. Susan clutched her arm, crying.

“I’m sorry Daddy. Please, I’m so sorry.”

“Not yet. But you will be.”

“What was that? What did you inject me with?

“You’ll see.”

Susan started to feel heat in her pussy. First it was just warm, but then the heat started to build. Hotter and hotter. Until it was almost unbearable.

“Daddy, what did you do to me?”

She looked down and saw a wet spot on the front of her jean shorts. Her pussy was leaking. Embarrassed, she realized fluid was running down her thighs too.

“You dirty whore, your body is actually excited.”

“No Daddy! It’s not my fault! It’s whatever you put in . . aaaggghh!” She fell to the ground as Tom’s hand hit the side of her face.

“Don’t make excuses slut,” he said coldly. She got back to her feet, tears running down her face as juices ran down her thighs. She realized suddenly that her shorts felt tight. She looked down and immediately saw why.

Her flat stomach was bloated, pressing painfully against the jeans. As she watched in horror, the top button popped, allowing her belly more room.

“Daddy, what did you do?”

“Well look at that. That perfect body of yours isn’t so perfect anymore, is it? Looks like you’re growing quite the belly there, slut.”

“No! Please, Daddy!” as Susan screamed, her stomach continued to bloat, swelling as it grew rounder, pushing the zipper of her shorts down as it pushed out over her jean shorts. Susan was about to scream again, when she lost her breath for a moment. It became harder to breathe. It was like her chest was in a vice. Feeling through her shirt, she could feel her training bra stretched incredibly tight across her chest. Suddenly it ripped open and she took in a deep gasping breath. Looking down she saw her previously flat chest now had quite significant tits filling out her t-shirt.

“Daddy, please stop this.”

“It can’t be stopped Susan.”

“I’m scared.” She bit her hand in pain as her breasts continued to swell. Her t-shirt was now stretched obscenely off her D cup tits, the huge hard nipples clearly visible through the fabric. The shirt itself started to soak through under her nipples as milk leaked from her engorged nipples.

“Oh God,” she moaned embarrassed. There was a puddle forming under her as juices continued to run down her thighs. Her jean shorts were wedged open as her belly swelled over top of it. She now looked like she was about six months pregnant. But the shorts were incredibly tight on her ass too, cutting into her flesh. She moaned in pain as her body rebelled.

“Please Daddy, make it stop,” she pleaded. She screamed as her shirt began to rip on her chest. It was stretched to the breaking point across her now DD tits. “Daddy, it hurts!”

“Then push Susan. Rip through your clothes. Push!”

“Aaaaggghhh!” she screamed as she pushed out. Her tits swelling visibly as they ripped through her shirt, milk flowing down the huge round mounds. She fell to her knees, panting and crying. Watching her transformation, Tom was as disgusted with her as ever, but his cock was now rock hard in his pants. He pulled it out, stroking it as he watched his daughter lose the battle to retain who she had been.

On her hands and knees crying, Susan’s jean shorts started to rip. First a small rip at the top, then it spread right down the ass crack as Susan’s swollen fat ass burst through its prison. Susan looked down at her body, crying in horror. Her fat swollen belly looked about 8 months pregnant and it rested on the ground beneath her. Her huge tits were E cups, hanging obscenely off her 15 year old frame. Her tight pretty ass was now fat and swollen. Her pussy was still on fire, made worse by the fact that her panties were stretched beyond recognition, wedged into her cunt and ass crack painfully. Tears were pouring down her face.

When she looked up, her Dad’s cock was in front of her face.

“Daddy, no. . . “ He reached down and closed his fingers over her nose. A moment later she opened her mouth to breathe and he shoved his cock into her throat. He pushed his cock in deep, fucking her face brutally.

“This is what you need isn’t it, you nasty little whore.”

She cried as he fucked her face, but instinctively, she was sucking him deeper and deeper.

“You like to suck your Daddy’s cock, don’t you, you fat little slut!” Tears ran down her face as she sucked his cock. At the same time the fingers of one hand drifted to her burning pussy, rubbing it, finally giving it the contact it had craved since she had been denied her orgasm with the pigs.

Tom pulled his cock from her mouth, slapping her face with it.

“You want this, don’t you, you dirty fucking bitch?”
“Please Daddy. Don’t do this.”
“Open your mouth, you fat whore.” She opened it immediately as wide as she could and her pussy surged with pleasure when he shoved his cock back inside.
“You’re fingering yourself, aren’t you? You dirty fucking slut! You like this, don’t you?”

She shook her head. “No Daddy, I can’t help it!”
“Make yourself cum while I watch, you disgusting little whore.”
“Please Daddy, no. Please! I don’t . . oh god . . I . . I don’t want this!!” she was screaming as she rubbed her pussy furiously, shoving fingers harshly into her dripping hole. “I . . .DON’T. . . WANT . . . THIS!!! OH . . . .OH . . . FUCKKKKK!!!”

She screamed as she came hard. Her pussy squirting cum down her thighs and onto the floor. Her nipples tingling and milk flowing. Electricity ran through her whole body as she came. In her ecstasy her body released her bladder, and piss flowed from her pussy together with cum, running down her legs and pooling on the ground beneath her.

“You just pissed yourself, you sick little whore,” she heard her Dad’s voice. But this time it was behind her. She tried to stand up, but he pushed her back down. She could feel his cock rubbing against her pussy.

“No Daddy, please!”

“Isn’t this what you wanted? To be mounted like a sow? Fucked like a bitch in heat?” He continued to rub his cock up and down her sopping wet slit, teasing her, threatening her.

“Please don’t Daddy! I never have!”

“Afraid of getting pregnant? It’s not like you could get any fatter, you disgusting pig!”

“Please, don’t put in me!”

“I don’t think I’m ready for your whore piglets around the barn anyway,” he admitted as he pulled his cock up her slit and then continued up her ass crack. “This will work for both of us though.”

“Wait! No!” She tried to protest, but it was too late. Tom spread her fat ass cheeks apart and pushed his cock into her tight, virgin asshole. He pushed hard and fast, having no mercy, giving her ass no time to adjust. She screamed in pain as his head pushed in, penetrating her tight hole.

“Daddy, don’t!!!” But as soon as he was in and thrusting hard, fucking her ass, her body was bucking back against him, betraying her as it had since it first embraced the transformation. Her hips were slamming back against him, trying to get him in deeper, craving to be fucked and violated, even as she screamed in protest and cried in pain.

“You love this, you fucking whore!” he screamed. She cried, trying over and over to deny it. But her pussy was leaking again, more and more. She was on the verge of cumming just from his cock raping her asshole.

“Do you want me to stop?” he asked. Each stroke went balls deep as her ass opened up for him.

“Please . . . please Daddy.” She moaned.

“You disgusting little pig!” he shoved his fingers into her dripping snatch. “What’s this? If you don’t like it, what the fuck is this?”

“I’m sorry,” she sobbed. He put his fingers to her mouth and she sucked them in, sucking her cum and piss off his fingers even as she cried.

As he fucked her ass, she started to feel pinpricks of intense pain down her fat torso. Looking down she saw two nipples burst through the surface of her skin on either side of her fat belly. She screamed in horror and started to cum.

“Oh god! Oh fuckkkkkk!!!! Uuugggghhhhhh!!!!” She screamed as she came over and over. She reached down and cradled one of them new nipples, feeling it swelling into a small tit. She went back and forth between them, her fingers massaging, pinching, coaxing the breasts as they swelled down her stomach.

“That’s it you nasty little sow! Cum with your Dad’s cock in your asshole!”

“I’m changing more!” she screamed. He ran his hands down her obese belly, finding the new tits.

“Growing into a perfect little pig slut, aren’t you?”

“The more I cum, the more I change!” she realized horrified.

“You want me to stop?”

She turned to look back at him. Her nose had flattened and swollen into a pig snout. Her ears had stretched. Her face, though still human, was much more pig like.

“I . . .I . . .”

“Do you want me to stop?”

“Please Daddy. If you don’t . . . I won’t be able to stop.”

“Stop what?” he said, continuing to fuck her ass.

“The pig. It wants to take over. It’s getting stronger.”

“Do you want it to take over slut?”

“I can’t. Please Daddy, make it stop.”

“What does the pig want, Susan? What does it need?”

She looked back at him, her eyes filled with tears.

“Tell me you fat little bitch. What does it want?”

“It. . . it wants you to rape my fat cunt. And cum inside me. It wants you to breed me like the fat, big titted, perverted little pig whore I am.”

He pulled his cock out of her asshole and shoved it straight into her soaking cunt. She screamed immediately. He grabbed her fat hips and fucked her hard, using her pussy, abusing it. He fucked her hard and rough, bottoming out inside her fat slutty hole. She started to cum right away, spasming and gasping.

“Ohhhhh yessssssss!!!” she screamed, lust overtaking her.

“This is what you wanted? To be fucked like a sow in heat?”

“Oh fuck yes! Just like that dirty little pig in the stall. No choice. Rape me Daddy! Rape your nasty little slut!”

Tom fucked her cunt harder and harder, pulling her hair roughly as he used her. The smell of pussy juice and urine was overpowering. She was bucking like a wild animal. Milk running down her fat tits as her body revelled in its change. Her pussy spasming in pleasure as it finally beat down her mind.

“What happened to you Susan?” he asked as he slammed into her pussy. He was getting close and she could feel it. His words sobered her for a moment. And she looked down at herself, bloated and fat, multiple tits all leaking milk, her arms and thighs swollen and thick, a huge ass spread open and her father’s cock spreading her underage cunt lips obscenely over it as she leaked cum and piss onto the floor. Tears fell from her eyes for the last time.

“I was a beautiful girl, wasn’t I Daddy?”

“You were.”

“Not anymore.”


“I’m just a disgusting, fat sow. That beautiful innocent girl is gone Daddy. I’m a perverted, underage, little fat pig cunt. And I need my Daddy to rape me till I’m preg.”

“Yesssssss! Take Daddy’s cum you sick little whore!”

She screamed in pleasure and release as she felt shot after shot of his cum pouring into her, filling her up.

“Yessssssss Daddy!!!!! Breeeeeeeed me!”

She came in waves, piss pouring down her thighs as he filled her with his own cum. Finally in disgust he pulled out of her, stepping back. She was rolling on the ground, covered in piss, milk and both of their cum. She was holding her enormous belly. He was certain she was pregnant now.

“You live here now. In the barn.”

“Yes Daddy,” she purred in post climax bliss.

“You’re not my daughter anymore Susan. You’re just a dirty little pig.” With that he walked out of the barn, leaving her there wallowing in her fluids. After a moment she got up, on all fours and waddled over to the bag of feed she has opened earlier to feed the animals. She shoved her face inside and began to eat. She was eating for more than one now.
