Hot experience. Reminds me of a time more than 20 years ago when I was at a nude beach in Marin Headlands with a bottom friend of mine. We were lying near many other sunbathers with his backside to me. After a while, my cock started leaking lots of precum (which is common for me) and he started rubbing his hole against the head of my dick. We were lying close enough to where no one noticed what was happening. Before long, my cock slid in his ass, with the aid of my precum, and we were just stationary, with my dick completely lodged in his ass chute. After a while, I started feeling myself getting close to orgasm, from the tight warmth of his hole around my cock,so I told him I was about to shoot. At the moment I lost control, he pulled away and I shot my load on the beach blanket. There were people within a few feet of us, but no one ever noticed.
