Amateur step sister gets fucked after a date with my boyfriend

So, I went out on a date with my buddy's significant other and things didn't quite work out. Now, my roommate's new girlfriend is hanging out in my dorm room in the same dress she was wearing earlier. I'm not even kidding, it's like she's trying to drive me crazy or something! Anyway, I decided to take a little revenge and called up my friend's roommate. She came over and we had a good old-fashioned chat about my predicament. It turns out, her butt is freakishly huge! I mean, it's not every day you see a girl with a booty like that walking around. So, as we were talking, things got heated and we decided to take things to the next level. We started making out and before I knew it, we were fucking like wild animals! I guess you could say I got a little more than I bargained for, but hey, it was worth it!.
