It started with me having problems with the writing style - too many info in not enough sentences. When I got used to it, there were problems with the story. As far as I understood Nick was told by his co-workers and his sister about the bet. Why then was it such a surprise at the end of the story for him? And the big sex-scene - well, my brain is like a sieve, but I remember reading somewhere (perhaps in one of the Gayology 101 discussions?) something that I think was written wrong in this scene. Yes, it was just a small niggle, but in the end in a short story like this it all adds up.
