Masturbating at the beach
I went on vacation to Hawaii and I was so horny the whole time because there were so many hot girls. I masturbated in the ocean during the day making sure the water level was above my shoulders so nobody could see. The salt water didn't feel so good after I came. I also walked back to the beach at night and rubbed one out on the sand. Nobody was there and I had the ocean to myself in the dark with the waves crashing. It was one of the best orgasms I've ever had
