Karen has been Rachael's best friend for years and during that time has grown close to her daughter, Mandy. It was always innocent, but now that's she's 19, Karen can’t help notice what a an attractive young woman Mandy has become. She finds herself watching Mandy swimming with her friends and fantasizing about her. She feels guilty about it, but there's nothing wrong with a little harmless fantasy.
Then Rachael tells Karen she caught Mandy not only watching Lesbian porn, but masturbating with her friend Kelly's panties. It is obvious Mandy is curious, but according to her, she is afraid to try anything.
Karen tells Rachael to let her talk to her, seeing she was in a similar situation as a young girl she can help her. Rachael thanks her, but little does she know what Karen has in mind is more than just a talk, but a private lesson with an experienced teacher!
