My wife and I visited Croatia, Bosnia and Slovenia a couple of years ago, and while on the coast of Croatia, we sought out a nude beach that had a racy reputation online.
We arrived relatively early, around noon, and the beach was occupied by only a few naked couples, mostly in their thirties, forties and fifties. There was also a couple in their late seventies, both nude, who had set up chaise lounges to watch the coming action.
At first, not much happened. A few single men wandered up and down looking at the naked women. I joined in and soon discovered that the north end of the very rocky beach was where the gay men were. I watched one pair in the bushes... one young guy was kneeling and busily sucking the penis of the second and stroking his own penis at the same time. I didn't stay and watch too long, but I must admit my own penis got quite hard, as I watched them.
I started heading back to where my wife was, when a short man a bit younger than I was motioned to me from the edge of the trees. I went over and he proceeded to vigorously suck my penis with a fair bit of talent. I didn't stay for a happy ending, and continued my stroll back down to the rocks and south along the beach.
Along the way I passed a fit young man with a very long penis who was standing alone and masturbating for anyone who wanted to watch. While I was wandering, more people had arrived, and I noticed several couples involved in foreplay - the women masturbating or sucking their partners cocks, and men finger-fucking their ladies. Any couples doing anything particularly interesting soon collected a group of single men, who stood in front of them and masturbated while they watched. I noticed one couple in their thirties. He was slim and kind of goofy-looking, she was plain and a bit on the chubby side. They were standing watching a man finger his wife. The chubby woman was playing with her small tits and hairy cunt as she watched the performance.
When I got back to where my wife and I were sitting, a middle-aged German couple had set up next to us. The man proceeded to spread her legs and shaved her pussy, to the delight of a large group of single wankers.
In front of us, a middle-aged woman proceeded to suck her husband's cock. I stood up to get a better view, and the husband began staring at my cock until he spouted a huge stream all over her tits. He continued to look in my direction for the rest of the afternoon. Part of me wanted to go over and stand above him and masturbate while he watched.
One couple in their thirties attracted a lot of standing watchers - and not just masturbating men. He was vigorously finger-fucking her and she was putting on a quite over-the-top performance of moaning and screaming as she came. They did this every half hour.
My attention was attracted by another couple. The modest-looking but attractive wife was lying on her back, gently fingering her cunt. Her husband sat on a rock just behind her head, his cock bent down so she could suck it. I confess that during the afternoon I made it quite clear to this women by my glances that I enjoyed her slim body, her firm medium-sized tits, and her completely shaved cunt which she often pointed in my direction.
