Ty wishes Jennifer to be transformed into a cow.
Not even a moment after the wish, Jennifer puts her hand on her head.
''Oh man, looks like I have a headache. A bad one, too'' said the girl.
Walking to the mirror, she stumbles halfway only get back up a few seconds later.
''Ugh, these stupid shoes are always making me lose balance!'' yelled Jennifer.
She eventually gets to the mirror and begins patting her head again.
''Seriously, though. What is with today?'' muttered the cow-to-be.
Suddenly, Jennifer's short shorts felt a great deal tighter than before. Wondering what was going on, she removed them.
Now in panties, she gasped in horror as she saw her ass growing bigger by the second.
''What's happening to me!?'' said Jennifer.
She quickly looked back at the mirror to reveal that her ears have gotten bigger and hairier with white hair. They were cow ears!
''Oh fuck, oh fuck, I'm turning into a cow!'' yelled the changing Jennifer.
Her chest felt strange, so she stripped her tank top, leaving her in her bra and panties.
Jennifer stared at her breasts. They were rapidly growing too!
But the worst was yet to come as she felt a bulging coming from her panties. As it grew bigger and bigger, Jennifer felt an uncontrollable need to pleasure herself.
Firmly holding her newly grown teats under her underwear, she moaned loudly as milk squirted from her now full sized udder.
She let out a clear ''Mooooooo!'' before realizing what she had just done.
''Oh... what am I doing!?'' said the now panicking Jennifer ''I need to get help!''
Running to the locker room's exit, the girl tripped several times before reaching it. Her huge tits bounced as she ran.
Ty, who was still watching the whole thing in his invisible form, smiled and wished that the door would be locked.
As Jennifer reached for the door handle, she wasn't able to open it.
Without warning, she felt herself lose balance and fell on all fours.
She screamed as her hands and feet merged together to form hooves. When she tried to get up, she couldn't.
Jennifer's ass and breasts grew so big that both her panties and her bra simultaneously burst, making them bounce around as if they were made of Jell-O.
''I don't want to be a cow!'' uttered a miserable Jennifer.
As she said this, a new cow tail grew from her behind. She was basically a hot girl with huge tits, ass, an udder and the ears and tail of a cow.
Once again, Jennifer felt a rush of heat coming from her udder and her breasts. She layed on her back and tried her best to play with herself using hooves.
As she reached orgasm, a stream of milk leaked from both her teats and her breasts.
While she was busy, Jennifer was covered with a layer of thin black and white fur.
As soon as she finished, the girl-cow stared at her new body, hoping it was the last of the transformation.
However, her mouth soon started growing.
''No!'' said Jennifer ''I-I... Mooo... don't.... moooooooo.... wanna be a..... Mooooooooooo!''
The now speechless Jennifer watched as a snout finally grew from her face.
Her transformation was complete. She was now a vaguely human shaped cow.
Although her mind was intact from the change, she felt herself needing... a mate. A strong bull, at that. Her human side revolted the idea at first, but she was a cow in heat, and she needed a mate.
