Breeding My Roommate's GF Behind His Back!

Last week I was looking for my favorite pair of pants and I couldn’t find them. Then I realized my roommate Matt borrowed them a little while ago and never returned them so I went to look for them. After knocking on the door and hearing no answer I decided to go look in his room while he wasn’t around but as I opened the door I caught his girlfriend Sam masturbating. That was pretty awkward so I explained the situation to her, apparently she was pretty horny cause she decided then to use my dick instead of her fingers. No wonder Matt really likes to hang out with her cause she’s a really fun girl. She’s got a big ass and some huge tits, not only that but she also loves sucking a big cock and getting pounded. Needless to say that I found way more than I bargained for and I’m not mad about it. Her pussy felt so good I couldn’t help but finish inside her for a nice cream pie she can remember me by. We promised to not tell Matt and hopefully I can get some more action next time she’s here and
