Jon waited for several minutes, to see if his transformation would completely incapacitate him. When it didn't, her took his clothes off to see if he could see anything different about himself.
Jon quickly found there were bumps were his nipples should be, and dark splotches of fur all over his body.
Then, he looked down at his crotch, only to discover his penis had been replaced with a vagina. He was now a girl.
Jon looked in the mirror to see all imperfections not already covered by fur disappear from her skin, as her nipples ballooned outwards into what were easily G cups.
But that wasn't the only changes to happen upon Jon, and he knew it.
Jon fell to his hands and feet as his legs began to crack until they were in a bovine digitigrade shape, and heard his tailbone unlock from his hips.
As Jon stood up, he noticed his hair had lightened to a dark red, like actually dark red, and not orange, with splotches of black dotting it as is grew longer and straighter, until it reached the middle of her back.
Splotches of fur of the same dark red as in her hair, and splotches of white fur covered the rest of her body except for a patch just above her crotch, as her lips thickened, and turned black.
He watched as her nose broadened and flattened, her nostrils growing in size as it merged with her upper lip. She could feel her tongue swelling as her teeth became broad, yet flat, and her cheekbones began to crack and her jawbones began to pop as they pushed out into a snouth maybe four inches in length.
But then came the ears which pointed out away from her head as they became cuplike, quickly assuming a bovine shape as a thick, rope-like tail pushed out from beyond her back, which grew to a 3-foot length as it became covered in the same splotches of color that covered the rest of her body, and her feet quickly hardened into cloven hooves as her torso assumed a hourglass shape, her hips widening as her butt cheeks swelled with smooth, but firm fat.
Now it was time for her last changes. In the area uncovered by fur just above her crotch, a bulge began to form, and quickly developed into an udder the size of a large cantaloupe as a large nosering was inserted through her nostrils, and her legs bulged with new muscle even as her arms became thin but dainty, and her pupils expanded to cover the entire whites of her eyes.
Jon decided she was too far changed to still be Jon, and decided to rename herself Jane.
