Sunday afternoon at the Folsom Street Fair. Was trying to make my way through to the front of the Treasure Island Media concession where I stood behind a guy stroking his rock-hard cock watching the TIM porn team fuck. He reached behind himself and began to rub my crotch. I eased in front of him for easy access to my butt, popped the button on my shorts, and with only a jock on, he had easy access to my hole. When he felt my wet lubed hole, he said "ahh shit I gotta fuck this ass"! He bent me over, with the crowd pressing in on us, and fucked me 'til he nutted deep in my ass. Everyone around us knew he had done the deed. It was a hot scene!
