My friend leaves me his house and his ass when his girlfriend is not there.

Video provided by gay roommy friend lets me stay at his house for a few days while they paint mine. i'm very lucky because his girlfriend is on a trip so i won't have to put up with her. my problem is when i arrive at my friend's house and find him lying on the bed. my eyes go to his upturned ass, i can't help but get my hands on it.
