Went to the beach the other day with a buddy, it was a hot day and we got very sweaty. We striped down to our swim wears without going to the changing room. I was wearing a very tight pair of red speedo and he a yellow tong, we swapped them in the open, the warmth and sweat of each other's made us very hard. His tong was so small it couldn't even cover my hard cock completely, but then I'm not shy. We fooled around groping each other's bulge and somehow attracted an audience, so we went into the sea and did some more there; rubbing our bulges and occasionally get our hard cocks out to play, it was such fun!
