A beam of sunlight breaks through the window, and rests on Mary's face. She blinks a few times, her eyes adjusting to the sun. Her mind was foggy, she couldn't remember what happened last night. She'd had something to drink?
"Oh, right the vials." she said, still muddling her words. Mary looked around and saw the vials were exactly where she left them. Her words came out somewhat slurred, due to her new lips and snout. Mary thought the vials gave her a hangover, and attributed her dazed state to that. She tried getting to her feet, but found something was off. She felt too heavy, and her center of gravity was all wrong. That's when Mary looked down and squealed (literally) in surprise.
"What the hell...?" she said.
Below, her feet weren't feet. They were hooves, pig hooves. And her legs were covered in long, wiry black hairs. Underneath, her skin was pink, and rough. There were bumps in places, and splotches of black. Mary lowered a hand to feel her new legs, when she gasped at what her hands had become. She vaguely remembered last night, and that her hands had become hoof-hands at some point. Still, it was a bit of a surprise. Mary bent over to inspect her hoof-feet, when she felt her piggy breasts rub against each other.
Wanting to get a complete image, she rushes to the bathroom, and stands awestruck in front of her full length mirror.
Instead of a face, she has a pig's head. A full piggy snout, and large flappy pig ears. Her entire body is covered in the black hairs that coat her legs. They thicker around her genitals, and thin around her torso. When Mary turns around, she sees her back is entirely hairy, and there are small droplets of sweat from her intense night.
Her body has gained a considerable amount of weight.The additional fat on her torso and hips didn't help matters. It tugged everything down. Her eight breasts, more like pig teats, hung low and sagged. The nipples, not erect a the moment, hung down to rest of her teats. They were long, probably about four inches while limp. A cold breeze rushed through the house, and suddenly Mary's new piggy teats were perked up and stiff, at least six inches long now, and as thick as quarters.
Mary reached a hand around to feel her tail, which was bouncy against her tight pink butt. Her rough nails dragged against something else, something wet. Her new pussy. It was moist, and the vein protruded a bit in areas. There was a considerable amount of pubic hair covered the outer lips, which were more like her pig snout lips. Thick, bulbous, pink, and very noticeable.
"Fuck!" Mary cried out as her two thick fingers prodded the lips of her pussy.
Then, something hit the bottom of her lower teats. It was hard, and Mary wondered why she could feel it. Pushing her breasts to the side, she almost fell over at the sight of her boar cock. It was twice as hairy as her pussy, and twice as erect as her nipples. There was an odd spiral to it, and the tip was pointed, not round like a human's cock. Below hung two enormous testicles, which looked like vertical footballs. They were definitely an animals, covered in rough skin, hair, and pulled down on the rest of Mary's nether regions. It made her pussy look at lot bigger than it was.
Mary poked her male parts, just to make sure they were real. Her balls tightened in their sack, and Mary's penis shook again. They were real. Mary pulled a shaky hand away, but it was no good. She came, sending wave after wave of cum flying through the air. Her pussy clenched and unclenched at the same time, leaking juice everywhere. The room soon smelt of musky pig sex again. Mary's snout made all sorts of animalistic snorts, as she drank in the intoxicating smells. She slumped against a wall, her nerves on fire and her cock slowly retreating back into its sheath.
"But why do I have both?" she thought, thinking about her porcine cock and pussy. That's when she remembered she'd had two vials. First the male pig, then the female.
"Guess you aren't supposed to mix them." she sighed. She stood again, this time more balanced. The longer she stared, the more she liked her new form. She jiggled her breasts a bit, and squealed when milk dripped out.
"I could get used to this." she said, running her hoof-hands up and down her hairy sides. Mary looked at the vials, and wondered what would happen if she added anything else to the mix.
The barnyard drawer was fully stocked, as were the male and female pig vials she'd taken last night. Mary stuck out a transformed hand to choose...
