You're alarmed enough about being transformed into a girl, but from the way this movie is going you'll be a donkey soon to boot. So you get out of your seat and walk briskly out of the theater. You scan the crowd as you leave and sure enough, people are suddenly noticing tails and donkey ears appearing on their bodies. You step out into the lobby and out the front entrance.
Once outside, you check yourself out in a nearby window. You look pretty hot. About 5 feet even, Long red hair, perky D-cup tits, round ass - this is the kind of girl you have fantasies about fucking. Of course, fucking isn't an option, because (1) you're her and (2) your dick just shrunk back into you and died.
So, what should you do now? Watch another movie to get transformed again? Try and find another way to change back? Or just cut your losses and accept your life as a voluptuous, sexy woman?
