My girlfriend [F] and I [M] loudly fuck back and forth until there’s a winner

My girlfriend and I went out one Friday night. Like most weekends, we drank and danced with friends and ended up back at my place. I just moved into my apartment and had one roommate. Usually he was doing the same thing, with a separate group—more on this in a later story.

Tonight was no different. My girlfriend and I met up and eventually ended up back at my apartment. No one was home. We just started dating, so we had not had this opportunity before. And to be honest, I didn’t know what to expect.

We start making out and dry humping. About par for the course as we led up to sex. I pull her shirt off and remove her bra, exposing her beautiful big breasts. To spice things up, I pinch and tug on her nipples. She bites her lip and lets out a moan. Then loudly says, “fuck babe, that feels so good”. I could sense something had gotten into her.
