I was having dinner at a friends house on the beach. A neighbor was one of the few guests. We had several bottle of wine and nobody was feeling any pain...there was a full moon and it was warm...I spent a good amount of time eyeing the sexy neighbor whom I had seen in bathing suit during the day. He reciprocated. I then said, the night is wonderful for a swim, anybody joins me? all kinds of comments followed and the neighbor said I may join you. I borrowed a towel and off I went. I undressed at the edge of the water and went in... could see the neighbor walking towards me, I got hard and let him see it. He got naked came in and we played like in the video, rolled in the wet sand, kissed, sucked and fucked him between his thighs, we were both hot and the rubbing made us both come. More kissing and got in the water to clean up. Toweled and got back to the party. He was partnered, I learnt, so that was it.
