Mary saw an open barn door, and smelled something cooking inside. She left herself be lead by the smell, and found it to be a pile of hay. She didn't question why it smelled so good to her, she just started eating. She hadn't realized how hungry she was until she started eating.
"You certainly worked up quite the appetite." a male voice said from behind her. Mary turned around, and saw an attractive, blonde haired man, probably around her age, wearing a lab coat and holding a blanket. He offered the blanket to her, Mary suddenly aware she was completely naked.
"Thanks." she muttered, her words a bit slurred with her new mouth. Cud had come back up, and she was mindlessly chewing it. She wrapped it around her body, it barely covered her.
"No problem. Name's Danny. I'm your caretaker."
"My what now?"
"Caretaker. Every subject is given one."
"I'm sorry but could you back track a bit. I'm a subject?" Mary asked.
"Oh right, sorry. I forget about the new rules. Let me start from the beginning." Danny said, motioning for Mary to follow him further into the barn. Mary did, noting how the barn wasn't so much a barn as it was some sort of makeshift laboratory. There was equipment everywhere, and not just your standard farm equipment. Things she imagined were taken straight from a sci-fi movie.
"I'm living in a move." Mary thought, glancing down at her cow body.
"Here, sit." Danny said, pointing to a bay of hay. He sat across from Mary, and began to explain.
"The company I work for, GenTech, created those vials. They used to deliver them with a letter explaining things, but they found that most people were more willing to participate if they just took the vials themselves. Anyways, subjects are chosen at random to participate in a sort of beta test. We're planning on rolling the products out to the public in the coming years, but we needed test subjects. And well, you can't very well put up signs that say, 'Willing participants for transformative trials needed. Must be willing to change species, or gender' on the local grocery story bulletin board." Danny said with a smile.
"So, is there a way to turn me back?" Mary asked.
"Of course. But if you do choose to return to your previous form, you won't remember any of this. A little bonus side effect, which works in our favor." Danny said.
"Alright, and if I don't changed back?"
"You've got a few options. You can let us examine you, or you can test more vials. Again, all up to you."
"How did I end up here?" Mary asked, looking around the barn. There wasn't anyone around except her, and Danny.
"Subjects are closely monitored during the first twenty four hours. After your second transformation, we moved you here and gave you a dose of the female-human vial." Danny said, holding up a half-empty vial for Mary to see.
"Why not make me entirely human?"
"You wouldn't remember anything. And, well, I got the feeling the second transformation wasn't on purpose."
"It wasn't." Mary said, vaguely remembering her change into a full bull. She was also a bit embarrassed, since that meant her perverted actions had been viewed. Which she hadn't wanted them to. Danny sensed her embarrassment, and quickly reassured her.
"Oh, there's no reason to be ashamed or uncomfortable. Trust me, there have more far more... interesting transformations than yours. Take me for example." he laughed.
"You?"
"Ya. I wasn't always a caretaker. I was a subject who joined the project. I wasn't always Danny, well not entirely."
"Really?" Mary asked, actually curious about Danny's experience with the vials.
"I thought the vials were a joke, so I took the male one. And after, I just decided to stay this way. Gotta say, it's much easier being a guy and it is a girl."
"Wait, then you were..."
"Danielle, ya." Danny blushed. Mary suddenly felt even more embarrassed for being attracted to her, or him. Then again, she wasn't sure if she herself was a he or she. She had gigantic breasts, and a set of equally gigantic male genitals. Which left her what, a shemale?
"I know this is a lot to take in. I'll give you a few minutes to think things over. Need me, just holler." Danny said. He walked off to one of the pieces of equipment. There he began working on something, Mary wasn't sure what exactly. Something computery it appeared.
She tried not to let herself get distracted. She had some serious decisions to make. Did she want to stay the way she was, and join this mad project. Or go back to her normal life, blissfully unaware of recent events?
