The witch used Jake's bewilderment and complete surprise to force her magical potion down his throat. The youngster spluttered and coughed as the witch stepped back, smiling widely. Jake hiccuped several times. That potion tasted rather bland but salty. And almost... grassy and ... flowery. And suddenly his eyelids drooped and he fell asleep. He was engulfed in a swirling whirlwind of magic and with a final puff of pink and violet smoke. When it cleared, a female centaur was lying on the floor of the cage. The witch's grin widened even further. Yes, she was THAT good. The best potions were the ones that transformed the victim - er, subject, instantly with lights, swirls and puffs of smoke instead of the slower gradual transformation which brought a lot of body horror and traumatized the subject. More complicated to create but she was talented enough for THAT. And she needed a centaur for the creatures' powerful magic, or rather, that of their mane hair and coat hair, not to mention the milk of females once they are with foal. Hence the witch's need of a female centaur. She'd get a male soon enough. First things first. And her potion had worked in an impeccable manner. Jake was now a female centaur, and a most adorable one at that, sure to attract the attention of any centaur male and enthral him. Her hair and mane were luscious blonde curls, thick and bursting with health. Her skin as smooth as butter drenched in cream. Her eyes would be as blue as the sky. Her face was round with full lips, very pouty, and her eyes were as large as a doe's. Her body was sleek, thin, and with a wonderful rump, matching her new breasts which were smallish but round and bouncy and as plump as ripe fruits. Her coat was as grey as a sly laden with clouds ready to quench the thirst of the earth, with delicate hooves as dark as night. Her hair and coat were shiny. She was slim, delicate and dainty. A real picture of bucolic mythological equine beauty. Utterly charming for any centaur, no doubt! Yes, she'd make the perfect mate! She'd be simply adorable with a few bows and girly accessories. Luckily, the potion included enough magic to impose to the former human male's mind new imperatives, tastes and desires. It would be hard for him to adjust but eventually it would occur. After all, he now possessed the equipment to make heathy pretty foals and produce lots and lots of milk, thanks to the potion which made Jake the epitome of centaur fertility and beauty. And if he resisted too much, well, the witch could enforce a bit more what his new nature n ow imposed upon him.
