About seven years ago I met a couple at Blacks Beach in San Diego. All three of us were nude and while we talked about various topics, sex was the main one. I noticed that she seemed interested in my nude body and I sensed they might want to party with me. I suggested we walk down the beach to a secluded spot I knew about that was about ten feet above the beach on a slope going up to the cliffs.
When we got there we laid down on our towels with her in the middle and we were all laying on our backs.
While we were talking about sex I saw that she had her shirt covering her face. He was playing with one of her breasts and she was playing with his erect penis. Well that got me hard and I thought I may as well play with her other breast. I started to gently caress it and was playing with her erect nipple. She increased the attention to his penis. He whispered something in her ear and she then removed her shirt from her face and looked me in the eyes and then at my erection standing at attention. She seemed to be impressed by my size (7.5' and very thick and wide) and soon had me in her other hand. She seemed to really enjoy having two hard penises in her hands and was doing a great job at giving both of them equal attention.
Her boyfriend was now masturbating her so she was really having fun now. Laying out in the sun having sex like this was overloading my senses and bringing me to the point of no return.
When I finally came I spurted a large load on her thigh and her blanket and the sand. We were all amazed by the volume that I unloaded and that triggered both of their orgasms. We cleaned up and returned to our places down the beach.
I never saw them again but will always remember that as one of my favorite times at Blacks Beach.
