"Wait, Katie you don't know what that will do!" Tiffany said. Katie didn't listen and drank the entire vial of red liquid. At first she didn't think anything would happen. And then a tingling ran up her spine and into her entire body.
Her cow/bull features began to fade. But unfortunately for her, her endowments remained. Her breasts returned, twice as large as before. And her penis and balls shrank, but did not disappear. Her tail was sucked back into her body, and milk stopped leaking from her nipples. Her vagina shrinks, the lips becoming smaller and smaller with each passing second until they're back to a more normal size. Color flooded back into her body, as her fur disappeared. Black spots faded away, leaving pink skin in their wake.
"Wow." Katie said, when her body was finished changing.
"Please tell me there was more of that." Tiffany said, staring at her friend's body. While Katie still had the male body parts, her body was more manageable than Tiffany's body was at the moment.
"Uh... try this one." Katie said offering the blue vial.
"I don't know Katie... what if it just makes things worse? These aren't even labelled." Tiffany said.
"How could things get any worse? You're still some kind of cow/bull hybrid."
"What if I end up a complete animal?!"
"Tiffany, I'll find something that turns you back. But we won't know which one works until you grow a pair and drink something!"
"Did you really just say, 'grow a pair'? Seriously?" Tiffany said, pointing to her gigantic nuts. Katie blushes and mutters an apology. She holds out the blue vial, and Tiffany takes it. She steels her nerves and drinks it in one fast gulp.
"Well?" Katie asked. Tiffany shrugged, nothing happening. Until a warmth spread to the ends of her fingers, toes, and all other body parts.
Katie watched in rampant fascination as her friend's animal features melt away. But she gasps as she watches Tiffany's breasts disappear. Her body loses its female curves, and soft features. Her jaw gains a hard edge, and her hips shrink. Though the fur disappears from her body, there is plenty of body hair left to cover her. A very sizable bush is left around her genitals.
"Oh, my, GOD." Katie said when Tiffany's transformation is over. Or maybe Tony was more appropriate.
