We had taken a few days off for a break and had decided to go down south to where I holidayed as a boy, a long pebble beach some 1.5 miles with some private little coves along its length. It was also well supported by Naturists, so stripping off was not a problem. We made our way along, past the normal wind breaks and ice-cream huts to where the site of naked bodies was the norm. I only had my shorts and trainers on by now, and Julie only the same, her top had long been removed, allowing the sun to beat down on the breasts. We walked for 5 mins or so longer, till we came to an area used by couples, where we both stripped bar for our trainers, walking on this beach was hard enough with footwear on!. There were two groups, one lying enjoying the suns heat, the other couple 50yards up the beach and at the top of the steep slope that ran from the waters edge to the steep cliffs behind. In fairness we had to walk half way up the slope to see them, but worth the effort as they had starting to play with each other, neither stopped, nor looked bothered as we walked within 10 feet of them and the sea, they both smiled, she carried on rubbing his hard cock whilst he gently rubbed her left breast. They were a couple in there 30’s she a nice tanned figure and he looked like he worked out a bit, not a full 6 pack but not flabby either. “They are making me horny, shame we can’t stop and watch”, I said to Julie. “You need to go and cool off, look at your dick “said Julie I will be up here when you’re calmer!! I took off my trainers and looked at my grown erection. I stumbled down short but deep pebbly slope to the sea edge and jumped in, boy it was cold after being in the sun, but refreshing, ten minutes in there and a quick swim and I was as normal, limp. As I climbed up the slope, still wondering where my trainers had gone, all I could see were a pairs of legs held high in the air, jerking up and down? I wondered where Julie had gone, but thought a little look won’t hurt anyone. A few more painful steps revealed the guy lying at the girls feet forming an “L” shape with his head between her of legs, his head moving up and down licking her clit, his hands and fingers displaying her moisture for me to see. I looked in amusement and rose to the occasion, her wet pussy lips begging for more. I just had to grab myself and start jerking off. But where was Julie? I couldn’t see her, just one my trainers on the pebbles behind the couple. It was impossible to walk without your shoes on these stones, I tried to scramble up the slope but made more noise than you could imagine, feeling uncomfortable I hobbled past the couple towards my trainer located just past the girls head I couldn’t see the other one as yet. In truth I had never been this close to another couple having sex before and it was all I could have hoped for, even now my cock was still hard. “Sorry about this,” I said as I bent down to pick up my trainer, where the hell was the other one? The girl looked at me smiling; the guy lifted his head and looked at me “she said you would be hard” “SORRY!!” I said in a raised voice. “She said that she would be watching, all you have to do is throw your trainer over your shoulder, into the sea if you wanted to join in! Put your trainer on and she would come out of hiding” “You’re having a laugh aren’t you?” I said. He started to lick her again; she started to fondle her breasts. I looked round, where the hell was she, was this for real? The girl stroked my leg, I felt my cock stiffen again, I just could not see Julie anywhere, she ran her hand up my leg and digging her nails in came back down my calf and down over my toes, I almost shot off there and then. In general if things look to good to be true they normally are, I picked up the trainer, opened it to put it on and slipped my foot in. “Sorry” I said. Julie appeared from behind a crevice in the cliff rock and walked towards me smiling. At about 10 feet from me I slipped off my trainer and launched it over my shoulder seawards. Smiling I shouted to her. “Now you stand there and watch you fucking tease, Oh, and any time you want to join in just pass me your trainers” I heard a laugh from the guy as I sank down to my knees by the girls head. She cupped by balls in her hand and took my cock I her mouth, her moist lips running up and down my shaft I almost shot off for the first time then. She started to masturbate me and suck at the same time, shit this was going to be over too soon. Julie stood excited her breasts pert her nipples hard, one hand playing between her legs the other trying to get the trainers off. “Let me try her for you”, said the guy nodding toward Julie, “you take over down here”. “Take your trainers off Come here, and lie down” I called to her. “No, No, Let her stand to start with” She hobbled across the pebbles and stood in front of the guy, “Face the sea, place your hands on your head, and part your legs for me “he instructed He moved between her legs, his face level with her shaven pussy and pulled her lips apart slowly exposing her moist inner-self. Blowing softly on her clit her knees shook, She gave out a low moan as his tongue touched her clit He sucked on her labia to sounds of “YES” from Julie. He worked his magic on her for several more minutes whilst I performed on my partner. Chris come and join Julie same position. As we stood there legs apart, hands on heads facing the sea, both receiving oral sex from different partners, we had attracted the attention of the other couple down the beach and they were coming in our direction but at sea level. They got level with us and just stood looking up at us, we must have looked like bad school kid with our hands on our heads, could see what was going on below waist level? I don’t know, the slope prevented a good view, but the excitement was enough, as they moved away I made my intensions clear and slipped between the tanned legs of my partner and hard up her cunt. The guy gave Julie the same treatment our asses moving up and down as one. I doubt I lasted a minute before pulling out and shooting all over her tanned body, but least I got to watch Julie have five minute of incredible pounding before she was covered in creamy cum. Not what we had planned or what we expected, but what an afternoon!
