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 don't lie in the sun very long. I get too sweaty and end up going for a stroll. I 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 energetically 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 hard, as I watched them.
I started heading back to where my wife was, when a short man a bit younger than I 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, thinking I should get back to my wife. I wish now that I had stayed with him longer. I have never had the opportunity to ejaculate in another man's mouth, but he was making me so aroused, that I think I would have filled his mouth with my cum if I had stayed. At any rate, I 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 masturbating in front of a crowd of eager watchers, both men and women. While I was wandering, more people had arrived, and I noticed several couples involved in foreplay; the women masturbating or sucking their partner's cocks, and men finger-fucking their ladies. Any couples doing anything particularly interesting soon collected a group of voyeurs, often 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-fuck his wife.
The chubby woman was playing with her small tits and vigorously sliding her fingers up and down her hairy slit as she watched the performance. A minute or so later, another couple came to watch. This woman was big - not fat, but very full-figured, and she was very attractive. When she saw what was happening, she decided to undress. To my sorrow, she reached under the back of her loose blouse and undid her brassiere strap. She then took off the brassiere under the blouse without revealing it. I had been extremely aroused, hoping to see her big titties filling out a sexy brassiere - I LOVE sexy, lacy, large-cup underwire brassieres. I still got a visual treat, however, when she lifted the blouse over her head to reveal perfectly-shaped deeply tanned tits with erect copper-colored nipples set on large dark copper aureolae.
When I got back to where my wife was sitting, a middle-aged German couple had set up next to her. The man proceeded to spread her legs and shave 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 and his wife 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.
