Today was another beautiful day for an early morning walk at Robert Moses Beach. I got there early and walked east a little bit and when it became desolate with people, I stripped to my thong and tshirt and just simply enjoyed the serenity. About 25 minutes of walking east, I came across an older gentleman who I would say was in his late 60s early 70s. He was laying by the water in just his speedo and having my sunglasses on I noticed his bulge right away. As I got close he said hello and the small talk amongst us began. I noticed his cock was getting hard as we were talking. He apologized but said my thonged ass was the culprit. I laughed it off and we continued talking. The conversation turned sexual pretty quick and by now his speedo was barely holding in his cock. He bluntly asked me if I'd ever had a BBC being a middle aged white fella myself. I told him no and that it honestly was one of my fantasies in my best shy, coy submissive voice. After I told him no, he leaned up, looked around to make sure it was clear and pulled down the front of his speedo to let loose his BBC. I'm guessing 8-9"? Then he firmly said, come over here and suck your first thick BBC. So I did one last look around, dropped to my knees and proceeded to suck his cock until he gave me his huge load on my thonged ass. It was such an unexpected experience and I'm already excited to go back to that beach again!
