Tramp stamp and sex

I was having sex with my best friend, I had informed before that I have a tramp stamp with my dads name above it. Tonight while we was having sex in his living on his couch ( I was bent over and he was pounding me from behind) he puts his hand on my hips and moves my shirt. Next thing I feel him moving my shirt back down,he lost his hard. ( I already knew when he put my shirt back down that sex was over)

We put are clothes back on. I could not help but laugh, because him and I have had sex many times before this,he has not ever left my tramp stamp stop our sex life till today. S*** happens.. Oh well !!!
