Seventeen-year-old Mercedes Ayres has an open-door policy when it comes to her bedroom, but only if the guy fulfills a specific criteria: he has to be a virgin.
Her system is simple, but it works. Mercedes teaches the boys how to have sex, giving them the chance to get their awkward, fumbling first time over with. All she asks in return is that they give their girlfriends the perfect first time—the kind Mercedes never had herself.
Keeping what goes on in her bedroom a secret has been easy—so far. Her absentee mother isn’t home nearly enough to know about Mercedes’ extracurricular activities, and her uber-religious best friend, Angela, won’t even say the word “sex” until she gets married. But Mercedes doesn’t bank on Angela’s boyfriend, Charlie, finding out about her services and wanting a turn. When Charlie gives her a gut-wrenching ultimatum, Mercedes doesn’t think things can get any worse.
In the wake of the worst night of her life, Mercedes’ secret is out, in the form of an incriminating video that leaves little to the imagination. With Angela not speaking to her and an army of seriously pissed-off (ex) girlfriends on her tail, Mercedes has to find a way to salvage her reputation and prove to her best friend that Charlie isn’t who she thinks he is— and figure out where her own heart really belongs.
