Wanking with my buddy

Mike comes round to your flat with a six pack of beers and a video. Neither of you has had a girlfriend for a while, but as far as you know, Mike is straight. Mike is skinny, but kind of cute and boyish looking. After a few beers, he says he's got a porn video - and wonders if you would like to watch it with him? He lives with his parents and has had the video a few days but hasn't had chance to watch it at home.
