Clare, my wife of many years and I enjoy a little naturism on the beach, where it is secluded enough to relax. One afternoon last week we had taken advantage of the early spring sunshine to visit a favourite local haunt of ours in Kent. Apart from a couple of single guys further up the beach we were alone. Our peace was broken by a group of lads heard comong along the beach; past experience has taught us that they have no respect for naturism in any form, so we covered-up before they passed. One lad seemed more interested than the others, and after a few minutes re-appeared looking cautiously round the low boulders behind which we were laying, now back to our naked state. He must have taken great encouragement from the fact that Clare was slowly stroking my cock, her legs apart to accomodate my carressing fingers. Our first reaction was to stop what we were doing. 'Sorry, I did'nt mean to peep, but my parents go nude on the beach, and I could'nt resist the temptation to see if you did too.' I was concerned that his mates might come back, and said so. 'No...we're from the Tech.College, they have a session at three, I'm done for the day.' Clare smiled...'How old are you...?' 'Eighteen last February....old enough, if you know what I mean!' His face creased into a cheeky grin, enough to seduce Clare. 'Come and join us, then...but no clothes!!' 'Really...? He loked nervously at me, but already in my mind was forming a very erotic scenario, which seemed to appeal to Clare. 'Yes..' I replied..'House rules, not a stitch!' He peeled off his tee-shirt, unzipped his jeans, and then sitting in front of us took off his trainers and socks. It was quite clear from the bulge in his boxers he had already got a hard-on, and he was a little self-conscious. 'Come on, gorgeous, lets' see you in all your glory' Clare encouraged. Off came the pants, to reveal a rock-hard cock pushed hard up against his slim stomach, the glans still hidden behind a generous foreskin. We made room for him between us, and I told him that he and Clare should just do what came naturally. He first leant over and sucked her ample boobs, presenting her with his rigid cock. Taking it in her right hand she pulled the foreskin right back to reveal a bright pink helmet, a thin trickle of pre-cum already moving down the shaft onto her fingers. Without any warning, he suddendly spurted several jets of thin, white spunk over her belly and tits, which Clare rubbed all over her torso.'Oh fuck....I'm sorry, I just could'nt hold back...I'm really sorry...' Clare pulled him down to her and gave him a big wet tonquey kiss...'Nice to see a good load anyday....lets just relax and try again later' Josh, as we then found he was called, did indeed relax, and encouraged to slowly explore Clare's plump body found the probing and carressing of her vagina and bum soon had him sporting another business-like erection. I had to work hard to keep my hands off his lovely youthful bum, my own erection now sprouting from my loins. But this was Josh's day; laying on her back with legs apart, Clare pulled him into her wet cunt, his rigid length vanishing into her until only the hairy balls were visible...bearing down on the small of his back, she held him motionless until she felt his passion subside a little, then started pulling him with quick movements further into her....'come on, fuck me, fuck me...' and fuck her he did, almost a minute of hard thrusting before he let out several loud grunts before collapsing over her, his load discharged. He rolled off her, still breathing heavily, his softening cock still oozing small drops of cum...within seconds I had replaced him and was completing the first of several of Clare's orgasms before I, too had emptied myself into her womb. 'I'de better go...' stumbled Josh, as he hurriedly dressed. 'Listen, Josh...you've made a mature woman very happy...thanks! With Clare's farewell he was gone. We looked at each other. 'Wow, lover, that was some hard cock....I wonder if I can get yours that stiff again...' Well, she did'nt, but if any adventurous eighteen-year-olds should venture past again, they can expect some real higher education!
