Invasion of Privacy

"Fuck you, Sis!" Marvin screamed, "First you steal
my body with some sort of magic spell, and now
you act like this body is still yours. You switched;
you're stuck being now. Deal with it! I don't know
why you feel like barging in on me in MY room
while I am changing. It's a total invasion of privacy!"

Moments

Jim was absolutely giddy when an accident with his father's new invention placed
him in the body of his college aged sister. She protested immediately as he started
feeling up his new boobs, but when they tried to use the machine to switch back, it
simply wouldn't work! Jim was ecstatic at the possibilities, but his sister rarely gave
him a minute to himself. He relished the few moments to change or shower when
he could really enjoy the fact that he was inside his sister's body, but if he took too
long, his sister would barge in. He knew he only had a few more seconds to get into
hr nightgown for the evening before she would interupt his moments of stripping
naked in front of the mirror. [LINK]
