Ken and Jill had been to the naughty naturist resort at cap D'agde several times, and had reached that unshockable point where nothing phased them. I was privileged to join them for a day this summer, having been number three in a long-term 3-sum, so no inhibitions between us. The morning was spent sunning and watching the rest of the world enjoying themselves, but after a picnic lunch things warmed up, and not far from us were three African guys pleasuring a middle-aged blonde, her husband looking on and encouraging them. The action was all oral, none of them attempted to fuck her, but the sight of three black cocks being sucked and wanked got Jill very interested to the point where she was openly wanking Ken and myself. Ken asked her if she fancied them doing the same with her: "Not likely...!" came the response, but not to be put off, Ken waited until their attentions on the blonde lady waned, beckoning one of them to come over. He introduced himself as Bo, shook hands with all of us then settled down facing Jill. No beginner he, he soon had Jill blushing with his chat-up lines, eg, "You guys don't know what a hot lady you have here!". He gently massaged his cock as he chatted so that it had an impressive semi from which Jill could not take her eyes. Ken moved round behind to allow Bo to move up alongside her. Ken whispered in her ear and she, having been encouraged, then took hold of Bo's cock which hardened visibly. He ran his fingers up and down her belly until eventually finding her cunt, which he entered with accompanying sighs from Jill. A few spectators were now starting to gather, the usual crown of guys all playing with their todgers. Jill became unhappy, and stopped proceedings there and then. Bo was crestfallen, but Ken indicated a more thinly populated area up near the dunes, and suggested we all move up there. The gathering-up of all our impedimenta took time, and by the time we had settled near another couple so wrapped-up (literally) in each other they never noticed our arrival, the momentum had been lost. We shared a cold drink with Bo, who seemed happy to stay, and began the task of getting Jill back up to temperature. Again, it was Bo, who's sensual caressing which got her breathing heavily again, getting things back on track. This time she took his cock in her mouth giving the purple-black head a vigorous sucking as two, then three of his fingers stimulated her wet cunt...the moisture on his fingers was evidence of that! "You going to fuck me, Babe?" he asked...before she could even think about it Ken said "Yes, fuck him hard, Darling....enjoy that lovely hard cock..." Bo laid flat on his back, pulling Jill over into 'cowboy'. Ken (always prepared) produced a condom, which Bo expertly rolled onto his erect cock...Jill tentitivly lowered herself onto it, shuffling her position until the head of his cock slowly vanished into her wet love channel. She let out a long gasp as she eased herself onto his full length-probably seven or eight inches-until just the hair on his stomach separated their bodies. I could contain myself no longer, and knelt up so she could suck my cock while she moved slowly up and down on his; Ken was wanking himself vigorously, fascinated by Jill's growing response to the feel of Bo's cock deep insside her. We had attracted a couple of male spectators, but now ignored them as we watched Jill reach orgasm, falling forward onto Bo as she reached the point of no return. He gave no sign of any result, but Ken and I were both surprised when ,as Jill rolled of him, we noticed he had filled the condom with a respectably quantity of spunk. Sitting up, he pulled it off his softening cock, and was about to bury it in the sand when Jill said "Give it here....", knotted it and put it in her handbag. (Ken later told me it wasn't there the following morning) I suppose it was her momento of a good fucking. Another cold drink then Bo made his excuses and left, as did our spectators, leaving Jill to wank Ken and I to completion in the afternoon sun. I suppose the lasting impression for me was that liberal sex was the norm, with no one taking any exception, and very little notice, of others enjoying themselves. Yes, we are going back next summer.......
