Mary grabbed a few vials from the box, as a grin stretched across her feline face. Opening the gender vial, she poured a few drops into a glass, not even looking at it. She then added the species vial.
"A nice dinosaur will work" she thought to herself.
She then added the rubber vial. She didn't see the point in changing someone, if they weren't going to be like her.
After that, she pour chocolate milk over it, unsure of the effect it would have. Passing the concoction to Brett, she smiled, and hastened him to drink it. Brett drank it down in one go, not really caring why.
Mary watched and waited, but nothing seemed to be happening...
Then she saw something change. Nothing big to begin with, just a slight greying of the face. Then the rest of his skin started to turn grey and shiny. Shiny like rubber. It had started working, and was changing Brett at quite a pace. He started to grow slightly, causing his clothes to rip in places.
"What have you done to me?!" He yelled, "What's happening?!"
Mary just laughed, as the young man's clothes tore off completely...then her laughter drifted away. Even though he was now naked, there was nothing to see, but a female slit. She'd added the wrong gender vial. It certainly showed when Brett's chest began to swell out. By time it stopped, he had breasts bigger then her's. As his dino tail pushed out of his backside, his legs began to shape into digitigrade, and rubber claws protruded from his feet. Scale shaped patches appeared on his rubber skin, and the transformation was complete.
Mary grinned...it wasn't quite what she wanted, but it was good enough. The question was however, what now?
