Fuck, I just couldn't keep my fingering...and cunt off my best girlfriend's boyfriend. When she was out shopping, I was only supposed to help him make the bed, but then I saw his bulge in his trousers and just had to suck his hot cock. That made him so horny that he just turned me round and fucked me from behind. Fuck, his cock felt so good and filled my tight cunt so hot. I think I'm addicted .... but then suddenly my best girlfriend bursts into the room and catches us .... Couldn't she have cum 5 minutes later?
