I go to nude beaches a lot. I enjoy being seen and the sexual tension at your typically beach. With the current trend to shave completely, it's nice to see women just laying out uninhibited.
I almost always end up cumming at the beach. Usually I will do it discretely by sitting up and gently rubbing myself to an orgasm, although one time I had a group experience.
On my particular beach I go to there are some rocks that generally give a little privacy from the rest of the beach. I had walked up there just to hang out nude. In the same spot were some other guys. We generally just stood around not really noticing each other. The guys were all soft expect one guy who was completely hard, although he was walking about like he didn't care.
While we were all standing there one of the guys started to stroke his cock. I glanced in his direction a few times and initially didn't know how to act. He remained soft for quite a while, but was well hung. At this point some of the other guys did the occasional tug, but nothing more.
Then he started to get hard and I began to feel my dick twitch. I thought what the hell, let's just go for it. I started to stroke my penis and cradle my balls. After my inhibitions were masked by my desire to orgasm I began to get really hard. I spat on my hand to provide some lubrication as started to really go for it. The guy who had been hard was now also stroking. The other three or so guys just watched and occasionally tugged.
The guy who started this was first to cum. His penis suddenly went to that familiar engorged state and he began to breathe heavily. Jets of semen shot from his shaft onto the sand. Everybody watched.
Just at that point a woman that had been walking by stopped and checked us out. She was naked and had a tiny little landing strip. That pushed me over the edge. I now began to feel the familiar tingling and once my orgasm peaked I shot four nice ropes out onto the sand.
The guy who had been erect all this time now came with a few dribbles of cum.
With that, I squeezed the last drops of cum from my shaft and walked back to where I'd been laying. What a great experience.
