Part 1 The meeting
It was OK being on holiday with parents and younger sister. OK, because Simon had always holidayed with them, and OK because the place was great. At eighteen of course he would have liked to have gone away with friends, perhaps girls too -- if less likely. But the plans he and his friends had sort of made fell apart rather easily. Perhaps they were not as keen as he was, so, in the end, he had gone with his parents and sister as he had always done. Nice accommodation, nice pool, nice meals in the evening, to say nothing of the lovely seafront, town and beach disappearing up the coast, but what does an eighteen-year-old boy really want to do? Laugh and lark with friends of his own age, drink beer and... well, ideally screw girls.
There were not a lot of ready girls to hand. Or for that matter lads of his own age. Indeed, he had spoken to no one. It was somewhat a place for families and retired couples. Historic, interesting, quiet and with lovely sandy beaches and safe sea bathing. Just not the place for the older teenager. Simon had taken to wandering on his own, which had been pleasant enough wrapped up in his own thoughts. Long exploratory walks: and that was how he had come across the naked man and woman. Of course, on the beach his eyes went to the pretty girls, such as they were, and women in their bikinis, but he had long since left the crowded beach behind. He was walking in pine trees to the rear of the beach, indeed rear of sand dunes backing the beach. A track leading back to the beach attracted him. Why, he was not quite sure. Perhaps it was the hope of discovering a couple having clandestine sex or simply women sunbathing naked. The chance to voyeur and, indeed, release some of that pent up semen teenage boys store in goodly quantities. If that was his hope, then he struck lucky. Gold even.
Simon would not have seen what he did see or anything like as much, had the woman not been standing looking away from him towards the sea. Bare breasted. He had not yet seen the man. Simon ducked, right down onto the sand, wriggling to the side, wondering where he might get a good view. But how not to be seen?
A vantage point reached, a cautious raising of his head and a peering through the long thick grass atop the dunes. Bingo! The lovely woman still there, presumably with her boyfriend, now lying down. There was a man there by her on a towel. The woman bare breasted, her bikini top to the side. Lovely breasts. Lovely bikini, actually, all green and white stripes, though Simon's eyes were on the woman. Women's bodies were his interest, not fashion. She was lying down, next to the man. He was in swimming trunks rather than shorts. Well-tanned and dark. A strongly built and tall young man. Maybe thirty years old. Simon's eyes took him in and then returned to the girl's breasts. Firm and delightfully curvaceous just like in his magazines. Pink nipples -- he wished they'd been red! In Simon's shorts his cock was hard.
And then the woman's hand, ever so casually brushed the bulge at the front of the man's trunks. Casual but deliberate. And she did it again. Simon stared. Was this sexual? The increasing bulge and then the appearance of the man's cockhead out of his waistband rather suggested it was! Were they going to fuck?
A whisper in the ear of the man and then a really long 'snog' with the girl's finger just lightly brushing the half-exposed knob above the waistband of the man's trunks, and the man's fingers rubbing the part of the bikini that ran, all green and white stripes, between the girl's legs. Had the bikini not been in place, Simon would have had a very good view of what girls keep between their legs. As it was, he could see the man's thick fingers certainly massaging the bikini material against, what he understood to be, rather soft and, maybe, if aroused, rather squidgy flesh. Another whisper in the ear of the woman and the man stood up. Now half in and half out of his trunks. That was certainly a cock -- thought Simon. And then the man pulled the trunks right down and off and reached to help his girl up off her towel. What a sight and what a cock! If only he had a camera. What a photo! Simon was suitably jealous. The girl's fingers encircled and squeezed.
And then down came the bikini bottoms revealing the girl's simply perfect bottom and a bush of golden curls complete with a little slit peeking through. Simon was missing nothing. It was so what he wanted to see. His eyes wide. He was relieved they were looking towards the sea and at each other. There was no way he could stop staring and duck down and hide. Such pleasing tan lines, as if the girl had a rather unusual bikini and he... well the standing 'salami' did not really make it look like the man was actually wearing pale, flesh-coloured trunks!
And off they went, hand in hand running towards the sea, naked and beautiful. It was a rather deserted beach. Behind them, discarded, their bikini and trunks, with no idea young Simon had been watching with a hard-on in his own trunks. He watched, delighted by the lovely wobble of the girl's bottom as she ran. Many times, Simon had watched the retreating bottoms of joggers in their running shorts but always shorts, never a naked bottom - until now!
With the couple away and closing on the sea, and likely to be away for a little time, Simon was rather minded to go and have a closer look where they had been, even take a very close look at that bikini. Best if he was naked like them. Best if his penis was out and conveniently 'to hand'.
Simon crept forward across the sand leaving his trunks behind, as discarded as the bikini or the man's swimming trunks, towards the towels. Down at the sea the couple were entering the water, splashing each other. It was so exciting to be approaching their towels completely naked, and tumescent, and then to be on the same beach towels as they had been a little earlier -- and naked as they were.
Sitting, he could barely see them over the dune. Lying down they were gone. Lying where the woman had been lying, his bottom probably in the very same depression she had made in the sand under the towel. His naked bottom where her bottom had been on the towel. But she had had no erection rising out of her curls. Not like Simon. He moved to the side, settling where the man had been. Positioning himself where the man's bottom had been and, therefore, his penis where the man's had been. Was his as big? Looking down Simon imagined the woman's hand stroking his cock. Simon imagining being the man or else the man, generously, offering Simon his place.
Lying there, eyes closed, penis erect imagining the woman's hand around it, moving it. Simon stroked with delight.
Sitting up he looked down to the sea. There they were swimming in the water. For the moment he was safe there on their towel, naked and invading their space. Sticking his erect cock into their space indeed! Where else could he stick it?
The girl's bikini sat lightly discarded on top of their beach bag. A grin and, of course, Simon picked up the bikini pieces. Such little scraps of material that held 'so much.' And, of course, he inspected the inside of the bikini to see if he could detect moisture -- feminine wetness from the man's fingers. Perhaps. And then he sniffed, pushing his nose right into her bikini. Very much invading her space. His hands then roaming over both parts of the bikini, feeling where breasts and sex were moments before. Such a bad or naughty thing to be doing -- if just so natural!
Another check on the couple and then he even tried the bikini bottoms on, feeling the material against his skin, his knob poking up above the waistband. So exciting. Not so much the putting on of a feminine garment but having his bottom, his penis where her bottom and her sex had been. A wank with them on, the front pulled down and tucked under his balls. Dare he? He pulled them off and set them down on the towel, the inside of the bikini bottoms set in a line to his front. Simon looks up and over to the sea. There the couple were, engrossed in each other. They were kissing and Simon could see the man was still as erect as him.
What a sight. Simon began wanking in earnest, great to imagine actually filling the girl's bikini bottoms with his cum. Imagining pouring his stuff out where her sexual lips, her sexual entrance, her clitoris had been rubbing. He looked up again, enjoying the sight of the naked couple as he wanked. The man and woman totally naked there in the sea. Might they copulate in the sea? Might the man's penis spurt?
Well, that was what, all of a sudden, happened to Simon's. White spurts 'erupting' from the end of his purple knob, pouring out all thick and warm, right onto -- indeed into - the bikini bottoms, right down the centre line! The green and white striped scrap of material there on the towel, set down right in the middle of the girl's towel. Whoops! He hadn't meant to cum, had only meant to pretend, but having started he did not think he could not rise quick enough to get to the sand before it happened; indeed in his sexual excitement and ecstasy found himself rooted to the spot, his knees not moving; his whole concentration on the ejaculation. So it was bikini or towel. A split-second decision. Simon stayed where he was, and the bikini bottoms got it all. All of it - and there was a lot. What an experience. What a thing to do! A gasping, erotic pleasure that the couple in the sea knew nothing about. They had their own pleasure and even before Simon had finished his cum, the man's penis was clearly in her vagina down there at the sea.
Simon tried to restore things to how they had been. Putting the trunks and bikini scraps back where he had picked them up whilst trying not to drip on the towel. Such a thing -- almost as if he had got into their bed back at the hotel after they had slept in it, and was now trying to return it to how it had been before he'd messed it up with his wanking. A glance towards the sea. How awful if they were returning and saw him. But they were engrossed in their own affairs.
