Bad Girls Doing Bad Things(2003)

A sweet girl learns to let the nasty side of her personality come out in this erotic drama for adults only. Karen is a nice young woman who works at a bookstore. However, Karen is a bit too nice for the tastes of her boyfriend Keith, who has a rougher idea of a good time than she does. Karen tries to convince Keith she's not a stick-in-the --mud by tagging along for a night out with his buddies, but when that doesn't do well, she turns to some bone-fide "bad girls" for advice on living on the wild side.
