[MF] Me (21m) and my girlfriend (21F) have post-argument hate sex (part 1)

It was 3am and my girlfriend and I were coming down from a 3 hour argument. We were sitting in our living room just chatting and cooling off the tensions. As we sat in the living room my girlfriend started to tease me.

“I bet you wouldn’t fuck me” “you wouldn’t hate fuck me” “you’re too pussy to fuck me after we fight”. My girlfriend was using reverse psychology to wrap me around her finger. I starting getting defensive to her saying that I wouldn’t fuck her and I said “You’re so wrong”. We immediately started making out with each other on the couch. We stood up and I pushed her backward from the living room to the bedroom while we continued to make out with each other. My hands were all over her petite body. My gf is about 5’1 and 90 lbs, tiny blonde girl. I’m 5’9 and about 180lbs, athletic build. My hand went up her oversized shirt and I found that underneath she only had a black lace thong on. I squeezed her small tight ass while we made out all the way to our bed.
