The other day, my roommate and I got to talking about sex. He's got a big cock and he's always bragging about it. I'm a girl with a big ass and I'm not shy about showing it off. We decided to give it a try and see what happened. He got me bent over his couch and started pounding me from behind. His big cock fit perfectly in my ass and we were both moaning in pleasure. He was fucking me so hard that he didn't even use a condom. After a while, he pulled out and I felt his warm cum all over my ass. It was the best sex of my life and we both were completely satisfied. We were both young, hot and ready to have some unprotected fun.
