"Danny?"
Danny looked up from his writing to see another subject walking into the barn. A well toned, generously endowed horse woman, Sara. She was nine feet tall, from her hooves to the tops of her ears. But she wasn't exactly a SHE. Like Mary, Sara had also take up the qualities of the opposite sex. Between her legs hung a stallion's cock and balls. But beneath, her mare vagina was hidden. Her luscious tail acted as a natural curtain for her genitals and asshole. No one, at least those subjects who made drastic transformations like Sara's, ever wore clothing around the barn.
Sara was proud to show off her beautiful deep chestnut fur, and her with white socks. She also had a white stripe running down her nose. She very seductively sat on Danny's work station, and let her maleness dangle off the side. The table buckled under her weight.
"Sara, where have you been?" Danny asked, looking up for a moment at his other charge.
"Out and about. Things to see, people to do..." she trailed off, snickering a bit.
"Well, glad to see you're back now. I was a little worried. You're supposed to check in when you go out." Danny reminded her, still writing in his notebook.
"You're such a party pooper these days. Maybe I could loosen you up?" Sara offered, leaning over the table. Her large breasts swung into Danny's face, but he merely swatted them away like they were flies.
"I'm working now. Besides, there's someone else for you to play with." Danny said, pointing to Mary. Sara looked curiously at the cow creature writhing on the floor in lust. She was vigorously rubbing her shaft, and her pussy was leaking copious amounts of woman fluid onto the hay beneath her.
"Geez, what's wrong with her, him?" Sara asked.
"Got a little carried away obviously. I tried to help her last night, but it would appear she's another lost cause. Until she masters the lust, she'll be nothing more than a horny cow." Danny sighed.
"Mmm, how did you help her?" Sara asked, licking her lips as her mind started playing out all manner of perverted scenarios.
"Thought maybe another bull would calm her down. Just seemed to make things worse. She grew a vagina during the night." Danny said.
"She didn't have one before?"
"Her name's Mary. She took the 'Bull' vial first. And you'll never guess what she did next."
"Try me."
"She actually fucked a cow. Like a real cow."
"You're kidding?! She went all the way?" Sara gaped. So few subjects were willing to get the "full experience" as Sara put it. Half sex as a half-human was intense. As a full animal, it was out of this world.
"Well not initially. She did her thing as a minotaur, before she went completely bull. I gave her a half dose of the 'Human-Female' vial, then brought her back here." Danny explained.
"No wonder the poor thing is like that. That bull must be fighting for control." Sara said.
"So, do you think you could bring our new recruit out of her cycle?" Danny asked.
"I can certainly try." Sara said, slowly approaching the shemale on the floor. When Mary caught the scent of a new female, she stopped what she was doing (deep throating her own cock). Sara's horse form whickered, and turned around. She flashed her horse pussy, her tail whipping back and forth in rapid succession.
"Wanna go for a ride?" Sara asked.
