Mary felt hungover. She hadn't felt this bad since that awful frat party in college. And oddly enough, it smelled exactly like a frat party. Stale sex, drunk breath, and some other awful smell Mary couldn't place. She rolled over and groaned. There was a cool breeze that passed through the room, and she suddenly felt chilled on her back.
That's when she shot up and realized she was completely naked. And covered in some disgusting sticky stuff. Her first move is to cover herself. Her second, figure out where she was, and how the fuck she got there. Mary looks around the barn, noting all the weird equipment. Obviously not standard farm equipment. What farm needs test tubes, syringes, complex computer looking things, and an X-ray machine.
Mary noticed a blanket next to her, and used it to cover herself, like she would if she'd just come out of the shower. She stood on weak legs and looked for any sign of life. Well she found it, but it wasn't what she was expecting.
A woman with long horse ears is standing, and apparently talking to someone in one of the stalls. Her ears twitched every so often, and Mary could hear the swish of a tail. Her face had a slightly equine cast to it, but it wasn't a true horse muzzle. There was rich chestnut fur covering her body, which was also completely naked. Her breasts were the size of bowling balls, probably bigger, with large, black nipples in the center.
Mary scolded herself from being turned on by the creature. Her arousal didn't go unnoticed, Sara smelled it and looked out into the open barn.
"Hey, look who's awake!" said a very happy Sara. Mary just stood there as the horse creature started walking towards her. She heard the distinct clop of hooves. The woman had a horse's legs, and rear. But the most surprising thing was the black sheath under her belly button, and over two enormous balls. Mary instinctively took a step back.
Upon seeing Mary's shocked, and terrified face, Sara stopped advancing.
"Maybe you better talk to her Danny." Sara said. Danny looked up from his desk, and then at Mary.
Mary watched this attractive young man approach her. His blonde hair was a bit messy, but he had a twenty carat smile, and a decent tan going on.
"Mary? You feeling alright?" Danny asked as he walked toward her.
"How... how do you know my name?" Mary managed to ask. Danny and Sara exchanged a look.
"You don't remember huh?" Danny sighed.
"No, what? Who are you? How did I get here? Where am I? And what the HELL is that behind you?" Mary pointed directly at Sara.
"You know missy that isn't very nice considering I helped you deal with your 'problem' less than twenty four hours ago."
"Sara, now's not a good time to bring that up. Just go get me some of the 'Reversal vial', alright?" Danny said. Sara flipped her mane and walked off. Mary couldn't help but stare at the mare's ass as it swayed back and forth. Her tail swished, and Mary grew hot at the sight of her horse lips.
"Come one Mary, I think I've got some old clothing of mine and Sara's around here somewhere." Danny said, motioning for her to follow him.
"I'm not going anywhere with you until someone tells me what the fuck is going on!" Mary said.
"Fair is fair. But you're not going to believe anything I say until Sara returns with that vial." Danny said.
He sat Mary down, and explained the past events. Everything from her receiving the vials in the mail, to her turning into a bull, to Danny and Sara helping her release some of her lust. By the time Sara returns, Danny has finished speaking, and Mary keeps shaking her head in disbelief.
"I think that my existence kinda kills your 'none of this is real' hypothesis." Sara said, handing Danny the clear vial.
"Alright Mary, I told you about the vials. How each one can do something different, invoke a different transformation. Just watch." he said. Danny stood up and undressed himself. Mary tried to protest, but Danny held up a finger. And then, he drank the entire vial.
As he lowered the vial, Mary noticed his entire body was starting to shrink. His reasonably well toned muscles began to disappear, and his blonde hair grew longer and longer. His brow and jaw softened, as did his hands. Danny's hips widened, and then his chest began to fill up. It slowly increased in size until it was about a DD cup. Last, his genitals were almost sucked up into his body. And in their place, was a cute pink slit.
Danny glanced down at his original body, and found herself a bit surprised. She's been a man so long, she'd forgotten what she looked like.
"Oh my god..." Mary said.
