Yo groaned loudly in her pen. She was overcome with feelings and emotions, just as Kameko and the doctor had intended. The hormones pumped into her feed through her body. She sweated heavily, the drops running down her body. Her udders swelled, hot milk leaking out of her engorged nipples. Her belly cramped badly, tying her into a knot in the tight pen. Her pussy lips were full and hot, her clit erect as her cum and piss ran down the inside of her thighs. The big tube of the thermometer in her ass shook as she tried to push it out but it stuck tightly inside of her.

Besides, she was angry. She wasn’t an animal! The only noises she had made since her kidnapping were grunts and moans. She had sounded like she was having really great sex. She knew she was not just overweight, she was fat. This was humiliating! She was a woman, not a sow pig! The injections hurt, not badly, but still, she felt like an animal, like the pig they acted like she was. Still, the idea of cooling off in a pen of mud wasn’t too bad.

She wagged her head, feeling the ring in her nose and the tag in her ear. How people would laugh if they could see her now. A calm, dignified housewife turned into a fat, naked, sex toy. She was in a                    leg restraints forcing her to crawl on her hands and knees. She had been forced to eat, sleep, and share a pen with two pigs, derisively called her “sisters.” She was being treated like a “mama” pig, a sow.

Kameko chuckled to herself as she filled out yo’s chart. The fat little housewife was getting the full treatment. She was being conditioned to being a real farm animal. As the doctor’s assistant, she knew how smart he really was. He was far more than a mere veterinarian. Per doctor’s orders, she had to keep that quiet. The patients might really freak out if they knew the full details of the operation.

Time for the next phase of the operation. Kameko used the control to lower the exam cage to the ground. She then opened the cage and attached the leash to yo’s nose ring. Yo left the cage at the first tug of the leash, following obediently. She waddled in her bondage, her belly and big udders rubbing on the floor.

Kameko approached a door and opened it, revealing the light of day. Yo blinked at the sunlight, stopping for just a moment. The familiar tug on her nose, reminded her of her new position, and she crawled outside. The tiled floor was replaced with hard packed ground. Kameko and yo walked over to a sturdily built fence, and the assistant opened the gate. She removed the gag, and then the thermometer. Yo crawled inside as expected, and stopped suddenly.

The pen was full of a thick brown mud about a foot deep. Her two pig “sisters” had their snouts buried in a feed trough. They grunted and snorted, oinking as they gobbled down their feed. Yo gasped as she felt the cool mud on her nipples and belly. Ironically, this seemed to make the liquid fire in her cunt even hotter.

Yo panted loudly. The mud seemed clean, though she could see the occasional worm. Flies buzzed noisily around the small herd. The other pigs just ignored them. Yo twitched as she felt their small feet crawl across her pink skin. Sow crawled over to the trough, seeing the usual pig pellets, wilted vegetables, and stale bread. Nothing was rotten, but it wasn’t anything a woman would eat unless she was starving.

She plunged her face into the mess and started to gobble the food up. The other pigs ignored her as they ate. Was she a sow? A big fat sow, ready for mounting? She seemed to feel a big boar corning her, mounting her, his big cock thrusting deeply into her piggy pussy. A big cock filled with hot sticky sperm, like the gang of men who had fucked her the day before. She looked around at the other sows, comparing herself to them. Still, things were so loose. She could have sex, without hassle. Just breeding.

Yo grunted and waddled away from the trough. She stopped for a moment, flies buzzing around her. Then she settled into the mud, rolling around in it to coat herself. She rolled over on her side, panting loudly. Worms slithered through the mud. She felt one crawl up her hairy pussy, its small head lightly touching her clitoris. Worms were fucking her. She sighed, feeling herself sinking deeper into the animal kingdom. Men, pigs, worms, and flies. What was next?
