I'm not a good man, and I've never pretended to be. I don't believe in goodness or God or any happy ending that isn't paid for in advance. In fact, I've got my own personal holy trinity: in the name of money, sex, and Macallan 18, amen. So when the gorgeous, brilliant Zenny Iverson asks me to teach her about sex, I want to say yes, I really do. Unfortunately, there are several reasons to say no—reasons that even a very bad man like myself can't ignore. She's my best friend's little sister. She's too young for me. Like way too young. She's a nun. Or about to be anyway. But I want her. I want her even with my best friend and God in the way, I want to teach her and touch her and love her, and I know that makes me something much worse than a very bad man. It makes me a sinner.
