Not The Cheaters Kid

Kacey had a...crappy...adolescence. But she spent the time planning her future, everything from her career to when she would get married and have kids by. And everything is right on track, until four months before her wedding, she finds why her fiancé has been so patient about sex. He has a girl on the side. She gets so drunk she does remember what happened, all she knows is she's naked in bed with a familiar looking blonde boy...whose name she doesn't even know.
