A boy, his boy, a girl, and some complicated turn ons.
Just call him the Jerk; everyone else does. He lives alone with his boyfriend (they're a nice couple) and harbors a crush on his boyfriend's sister (she's not really his sister). On one crazy, sexually-charged day, the Jerk is going to discover the secret they've been keeping and all three of them are going to have to rethink the shape of their relationship.
