A few weeks ago we were on holiday in Spain and I was on the beach by myself as the others had gone off somewhere. I was lying on my towel in my swimming gear and watching these girls play with a beach ball. I loved the way their tits bounced up and down as they jumped and ran after the ball.
As I watched I could feel my dick getting hard in my trunks which was both embarrassing and exciting at the same time. I was on my stomach and pressing down on my hard on. I found that if I moved about very slowly I could excite myself and start to work myself up but nobody would be able to guess what I was doing.
This went on for about half an hour and I could feel myself getting close to cumming. The girls were still playing around and I longed to shoot there and then. So I pushed down on my hard cock against the towel and felt my cream pumping out in a wonderful orgasm. I kept very still which seemed to make it even more intense. When I'd calmed down I got up and ran quickly into the sea so that I could clean myself up. That was some experience!
