Jacking off for strangers

I was at the nude beach yesterday and saw it had been battered hard by tides and the dunes were a lot smaller . I found a spot down the beach and didn't see a couple sitting back at the edge of dune. I set up my chair and stripped naked in the sun then sat down and spread out waiting to see who would walk by me. A few did 2 girls in there 20's and they didn't seem to be interested then a guy my age walked by and stopped in frot of me nd talked for a few minutes enjoying me sitting there naked . after he left I saw the girl in her 30's walk down near the water to feed the gulls. she knell down and sat there feeding them and looking around before turning to face me , I like this move but couldn't see her guy sitting in the edge of the dune but I sat and let het enjoy seeing a nude man. she finally returned to her guy and sat down but not far enough back so I couldn't s her. I was excited that a dressed girl with a guy would like seeing me naked and try to see my dick .A few minutes passed and I decided to get up and have a smoke on the back side of the dune looking over the swamp and how it had been damaged by the high tides. When I turned around I saw her standing up and looking at me so I faced her full on to let her see my body and cock easily. We stood there for a few minutes before she turned and sat down and I was really horny now after knowing she purposely was standing to see me naked and enjoyed it ,so did I . When I returned to my chair I sat down and watched to see what she was doing and she was looking again my way so after a few minutes I was playing with my dick and stood up o she had a good view of me nude again and don't care if boyfriend saw me and let her see me playing with my cock. She stared at me and didn't move away . I began to stroke my cock I was so excited by her and I continued as she looked at me and even talked to her boyfriend once but looked at me the whole time . It was just her and me actually and we both were enjoying the moment ,once she put her hand up to able her to see better I did cum it was fast but a wonderful feeling having a girl watch me and knowing her guy didn't stop her I loved it and sat for a couple minutes and then noticed that the tide was coming in fast so I stood up again ( her still watching and put on my shorts. At this point she walked down where the water was rising in front of me and took pics of it and me I saw and she was smiling ,I smiled back as I put my stuff away to go. I stood putting my backpack on and looked at her again as she looked back and wished amore time to play It could have been very exciting if guy didn't mind
