"Oh my god, get out of here you perv!" Evan swore at his brother as he covered his classmate's tits."You're the perv," Alex laughed. "Isn't the rule of Swap Class you're not supposed to do stuff like that?""Shut up and get out!" Evan yelled again. He was pissed off at being interrupted. He'd been feeling up his new body and had just started getting nice and warm and wet when Alex had burst in."You're gonna get in so much trouble," Alex teased."Don't you dare tell anyone.""I won't," Alex grinned. "If…""What?" Evan grumbled."If you fuck me.""Gross. I'm your brother.""Well, that body isn't."Evan had a point. And, besides, Alex was kind of horny and he did wonder what it would be like to feel a cock in his pussy."Okay," Alex conceded. "But just this once."But Evan enjoyed the sex so much that 'this once' turned into 'every day'.

Sebastian wakes up one morning in the body of Cindy, a cute young woman who lives in the dorm room below him. But his own (former?) body is still moving around, completely oblivious to Sebastian's confusion. What's more, Cindy is still conscious and thinks every sexy thing she's done is of her own free will in Suddenly Cindy 1, only available on Body Swap Stories and Smashwords. Preview here.
