Mike thinks he might like to date Emily, and so he invites her to a frat party. She declines: "You don't have to get me drunk, Mike. Lead me to your bed and tell me what you want me to do," she says. A guy can learn to handle rejection, when it's presented in that manner.
So next she has to bring him home for inspection at Christmas. Ooops. Mom is one of his former bedmates. In fact, she had been married to someone else when he received her as a very nice Christmas present several years ago.
This story consists of a very nice series of very sexy and interesting twists.
