I remember reading this some time ago, can't remember it though. But I'm pretty sure when the uke and seem first meets the uke seduces the seem into doing it (somewhat force) and I think the seem was in the ukes house because their little brothers were friends or something. It is like a college-uni theme, where the story revolves around that. and the seem apparently disgusts gays.
