"That was the worst snagglefuck I ever had, there we were, behind the bleachers, I had Susie's dress up around her neck and I was hammering her puss for all I was worth...how was I to know they had a camera back there? How was I to know it was connected to the main display units, and audio too....all the crowd saw was my butt pumping away with Susie's legs over my shoulders crying "fuck me you wimp, fuck me like a man!"
