A story about a gay guy who has a neighbor that has loud sex also because they have thin walls in the apartments. He gets propositioned by said guy because said guy thought he had a thing for him but really he was staring at his beer the whole time. Anyway, gay guy has an unrequited love with his best friend who always asks to borrow his room to have sex with his gf with. THIS IS GREAT. I loved it.
