Allison’s parents announced one morning that they were taking her to a medical appointment.

“It’s the school’s idea,” her father said, once they had her in the car. “They said a girl with fuckbags as big as yours needs regular checkups.”

“So you’re taking me to a gynaecologist?” Allison asked.

Her parents looked embarrassed.

“Actually, dear,” said her mother. “We’re taking you to a veterinarian.”

“I’m not an animal!” Allison objected.

“Well, it was the school’s recommendation,” said her mother. “And he’s much cheaper than a gyno, and apparently he’s very good with udders…”

===

The vet was a man who was introduced only as “Mr Culvers”, and he quickly separated Allison from her parents and led her into a room filled with various caged animals.

“Strip,” he told her, and Allison, helpless, had **** but to undress, until she stood before him completely nude.

Culvers got out his phone and took photos of her naked body, with a focus on her tits, pussy and ass.

Then he pointed to a steel table in the middle of the room.

“Up on the table,” he told her. “On all fours.”

Allison awkwardly climbed atop it and assumed a position on all fours, like a dog.

Culvers nodded – and then used straps on the table to secure her ankles and wrists in place, so that she couldn’t move.

Allison made a small noise of distress.

“Don’t worry,” he said. “I know what I’m doing. Biologically speaking, a teen girl with udders the size of yours has more in common with a cow or a female dog than a male human.”

This didn’t reassure Allison at all.

He took further photos of her in this position. He moved to behind her, reached out and spread her pussy lips apart, and took move photos.

“I feel embarrassed,” said Allison awkwardly.

“Any girl with tits like that *should* feel embarrassed,” said Culvers, unhelpfully. “Tell me, Allison, are you on birth control?”

“Yes,” admitted Allison. “I take the pill.”

Culvers nodded, and turned to a nearby computer and made a note.

Then he approached her again with a small device in his hands. He pressed the device between her shoulderblades, to one side of her spine, and pressed a button on the handle. Allison yelped with pain as something stung her.

“It’s just a microchip,” Culvers told her. “I’m a vet, not a doctor, so in order to give you medicine I need to have you in the system as a registered animal.”

He typed for a while at his computer, and then showed Allison the screen.

“See?” he said. “Your parents now own a female cow named Allison, who is being treated for udder sensitivity, low milk production and fertility issues.”

Allison noted that the file on the screen included the nude photos that Culvers had just taken of her. Anyone looking at the record would apparently see photos of her tits and cunt.

“Will people… see that?” she asked.

“Not unless they go looking for it,” said Culvers. “And see here? You’re not the first big-titted girl to seek treatment from a vet. There’s a special code we use for ‘human’ cows, and the pictures will only show to people who’ve entered that code.” He shrugged. “But yes, if the vet in the next town over who treats fuckbags like yours does a search for the code, he’ll get to enjoy your photos.”

Culvers pressed some buttons, and a new record appeared. It showed a naked blonde girl, about Allison’s age, with large breasts – although perhaps a little smaller than Allison’s.

“See?” said Culvers. “This girl is getting treated by one of my colleagues for udder-related attitude problems.”

One of the photos appeared to show the girl in metal restraints, with milking cups fitted to her nipples. Another seemed to show a man whipping the girl’s breasts with a leather belt. But Culvers closed the file again before Allison could get a closer look.

“Now,” said Culvers. “You’re going to need this.”

And he popped a rubber ball gag into Allison’s open mouth, gagging her, and then secured its straps behind her head.

“This is just because most girls try to scream for the next bits,” said Culvers.

Allison’s eyes widened in fear, and she made muffled noises of protest into the gag.

Culvers took out a large syringe and used it to draw up some green-coloured liquid from a vial. He tapped the syringe – and then injected it into Allison’s left tit, making her squeal, and then her right tit, making her squeal louder.

“This will just help you adjust to your biological function,” he told her. “The **** sensitises the udder, and promotes udder growth. You will feel pain and pleasure in your tits much more strongly, and they’ll likely swell up by another cup size. It will make it easier for you to focus on your fuckbags as the most important part of your body. We’ll have you back here every two weeks for another injection until the results are permanent.”

He gripped her tits, and gave each of them a squeeze and a tug, making Allison squeal again.

Then he moved behind her, where Allison couldn’t see what he was doing. There was a pause, and then she felt him manipulating her pussy, pulling at her labia…

… and then – OW! Stinging pain!

What had he done? It felt like – OW! And again, in the other pussy lip.

Had he just pierced her labia?

And before she could deal with that thought – OW! OW! The worst pain of all – directly in her clitoris. She screamed into the ball gag.

He felt her manipulating her sore pussy flesh some more, and knew that she was right. He had pierced her pussy lips and her clit, and now he was threading rings through the piercings.

Finally, he released her from the straps on the table, and un-gagged her, and got her to stand up. Allison wanted to examine her poor tortured pussy, and prod at its pain, but Dr Culvers instead took her wrists and strapped a leather cuff around each. Then he ran a leather belt around her waist, and clipped her wrists to a D-ring on each side, so that her hands were trapped at her side.

Then he invited her parents in.

Alison shivered in embarrassment as her parents took in her nude condition. Her father unashamedly stared at her naked tits and pussy. Even her mother was looking at her udders instead of her face.

“Your daughter Allison suffers from a very special condition,” said Culvers. “We call it Accelerated Female Instinct, or AFI. Basically her body very strongly feels the biological urge to become a factory for milk and babies. That’s what causes her enlarged breasts.”

“What do we need to do about it?” asked Allison’s father, still staring at her cunt.

“Well, the main danger with AFI,” said Dr Culver, “is when the body tries to fight itself. This causes terrible stress and can lead to complications. What the body wants to do is focus itself on Allison’s udders and cunt – particularly her udders – and what we want to do is allow it to do that, and remove any barriers to that occurring. As her body learns to divert blood from her brain into her fuckbags and pussy, she will likely become a fair bit stupider than she is now, and more lustful, but that will nevertheless be the healthiest and happiest version of your daughter.”

Dr Culver passed her father a packet of pills, and a prescription. “First of all, Allison will need to discontinue her birth control,” he said, “and take these instead. They will actually make her *more* fertile, and send her womb into overdrive. She will likely start to maintain a constant low level of sexual arousal throughout the day, and it may promote lactation in her breasts.”

Allison’s mother shifted uncomfortably. “Won’t that put her in danger of getting pregnant?” she asked.

“Well, first of all you need to accept that Allison’s natural biological destiny is pregnancy,” said Culvers. “That’s the thing her body was made to do. Those udders on her chest were made to fully feed a baby – or twins, even – with plenty left over. But I understand you might not be ready to deal with a teen pregnancy, so I’ve prepared a very simple precaution.”

He pushed Allison’s legs apart so that everyone could see her cunt better, and at this point Allison caught a glimpse of her new “improvements” in a mirror – inch-wide metal rings threaded through piercings in her labia majora and her clitoris.

Culvers knelt down and clipped something to Allison’s clitoris ring. It was heavy, and it hurt. She looked in the mirror and saw that it was a small cowbell, dangling from her clit by a short chain. The bell hung at a height that was halfway down to her knees, and when she swayed her body it made a surprisingly loud “clang”.

Then Culvers pulled her labia rings together, and threaded a small padlock through them. With a “click”, it snapped in place, locking her pussy lips together.

“With this lock, it is physically impossible to get a penis inside your daughter’s cunt,” said Culvers. He passed a small key to Allison’s father. “And you hold the only key. Even if your daughter is ****, they will have to settle for using her anus or mouth, and your daughter will be free from impregnation.”

He tugged on the cowbell, making Allison squeal with pain. “She can still pee in this condition, and if she desires sexual release she can tug on this chain here. Most girls can learn to orgasm from pain under these circumstances.”

“Now, this does require some special hygiene considerations. She won’t be able to wear panties anymore. The combination of her arousal, and the locked nature of her cunt, would simply be too unhygienic if she had panties keeping it all in. Her pussy needs to receive as much fresh air as possible. Short skirts are recommended.”

He smiled at Allison’s father. “And you’ll be responsible for unlocking her every 48 hours or so, and carefully cleaning her cunt.”

“That seems reasonable,” said her father.

“Thank you, Mr Culvers,” said her mother.

“And lastly, it’s important to keep Allison’s attention focused on her breasts, to promote that transfer of blood from her brain to her sexual organs,” said Dr Culvers. “I recommend that Allison wear one of these each day at school. Perhaps alternate them.”

The first was a bra, that looked on the small size for Allison’s current sizing, and the inside was lined with sharp metal points. Allison knew at once that if she wore it, her tits would be in constant agony throughout the day.

The other was a series of thick elastic bands, and Culvers demonstrated how these could go over the base of Allison’s tits, constricting the tits and inhibiting blood flow, to make the tits bulge lewdly and become purple and extremely sensitive.

“For her safety, she’ll need to temporarily remove these at recess and lunch,” said Culvers, “to let the blood flow back in. I’m told the feeling of the blood returning is absolutely excruciating, so I recommend she tug on her clit chain for a while before removing them, so that the endorphins of arousal can counteract the agony.”

“Thank you, Mr Culvers,” said her mother again. “And what about these restraints you have her in at the moment?”

“They’re yours to keep,” said Culvers. “Leave her in them until tomorrow, and keep her naked. She’s had an injection in her breast, and piercings in her cunt, and they’ll heal best if they’re not covered.”

He laughed. “Oh, and bring her back in two weeks, for a checkup.”

Allison was still nude and restrained that night when her father came into her room with a flannel and a small bucket of warm water.

“Time to clean your pussy, honey,” he said.

He carefully unlocked her twat, and then spread her pussy lips, and dipped the flannel in the warm water. Then he began to run the warm, wet cloth up and down across her twat, being careful to rub her clitoris on each pass, and push it up into her fuckhole from time to time.

Allison couldn’t help herself. She was naked, restrained, helpless, and it was her own father – and yet she was still becoming aroused.

The injections in her tits had taken hold, and they seemed to be throbbing even with no one touching them. When her father tentatively reached up and stroked one, his hand running over her erect nipple, she moaned.

Her father re-wetted the flannel, and brought it back to her pussy, pushing it insistently up into her fuckhole, while his thumb twined around her clitoris chain, tugging on it as he finger-fucked her with the cloth.

His hand tightened over her tit, squeezing it, as he looked into her eyes.

He had two whole fingers in her baby-tunnel – and then he crooked his fingers, in a beckoning motion, pressing against her G-spot.

Allison couldn’t help it. She orgasmed, right there, in front of her father, trembling, shaking – and squirting all over his hand.

“Messy girl,” said her father. “But you can’t help it, can you? This is what you were born for…”

He kept rubbing at her cunt, cleaning up her squirt…

.. and then he put the flannel away, and locked her cunt shut again, and walked away, leaving Allison trembling with humiliation, her cunt and tits still throbbing with lust, and her hands restrained unable to do anything to relieve herself.
