I have never been unfaithful to my wife.  Nor her to me.  Our story is not one of swapping, but of exhibitionism.

Some years ago, we were staying in Brittany.  At the time, I was obsessed by stone circles.  Stonehenge is one.  But like the other well known ones, Avebury,  Castlerigg, it had become like theme parks.  So we headed for Brittany.  We stayed at a very nice hotel in Carnac.

My wife Jen was supportive, but not obsessed, so I was conscious that her idea of a holiday was lazing by a pool or on a beach, so I was careful to ensure that her requirements were well catered for.  Our lazy days were spent either around the hotel pool or at a beach on the Eastern side of a peninsula that protruded into the bay, sheltered from the Atlantic winds and waves.

Topless was normal on the beach and around the pool and Jen decided to;

"Get a tan without white bits."

I was content to enjoy the view, but disappointingly, there were no nubile starlets present.

One evening at the hotel bar, we met another English couple.  Sophie and Paul.  We dined together, they were very good company.  We told them about 'our' beach.  They looked at each other, you could almost sense the telepathy between them.

"You should try the wild side."

Said Paul.

"That's where the nude beaches are," added Sophie.  "On that side, you can get a tan without white bits anywhere."

Sophie was one of those women who seem to be a natural man-magnet, the idea of her nude had my cock to attention immediately.

We finished the meal and retired to the lounge for coffee, the ladies took the oportunity to visit the powder room.  Together, as they do.  In their absence, Paul said;

"You should try the nude beach  it does wonders for your sex-life."

I could imagine, although we never had any difficulties in that area.

We tried it the next day.  'Wild' was the right word, those present were grouped in the Lee of the rocks and my only attempt to swim nearly ended in disaster, the undercurrent from the waves was so strong.  Most of those present seemed to be overweight  middle-aged men displaying their wares, but there were other couples and they could not keep their hands off each other's naked bodies.

Jen seemed to love it, she managed to position herself where everything was on show, it was not missed by the men present.  Several times, she asked me to apply suntan oil.  I enjoyed sliding my hands all over her firm naked flesh, but was very conscious of my almost permanent hard on.  Eventually, our pale northern skins cried enough and we headed back to the hotel.

We showered together, almost a repeat of the beach oiling ritual, but with soap.  Jen sucked my cock then insisted that I fucked her from behind with the water streaming over us.  I was more than happy to oblige.

We lay side by side on the bed, naked, recovering.

"Is it safe to assume that you enjoyed your taste of nudism?"

I teased.

"Loved it," she replied.  "It's so…  liberating.  Pity we couldn't swim naked though.  Can we go again tomorrow?"

My erection was back with a vengeance, fully recovered.  Jen leaned over and kissed the tip.

"Pretty please?"

She pleaded, then engulfed my stalk and sucked me to another powerful ejaculation.

Over dinner, we discussed our time on the beach.

"You certainly got plenty of attention out there."

I said.

"I know, it made me really horny.  One couple were actually fucking, did you see them?

I had noticed.  They were discreet about it, but it had been pretty obvious.

"Would you like that?  To be fucked with an audience?"

She didn't reply, but she was breathing heavily and her hands were shaking.  We fucked again after dinner.  Paul had been right.

We did not get the chance to try, the storm that the winds had heralded, hit the next day, the rest of the holiday was a washout.

Fortunately, our time in Brittany had been a short break, we still had our main holiday to look forward to.  Nothing had been booked, we had planned simply to take the car over to France and go where fancy took us.  I had a sneaking suspicion that it would be Brittany.  Jen had other ideas.  She called me over to the computer.  Gran Canaria.  I read the details.  It was not the swinger resort, but a hotel that permitted full nudity, the famous dunes were nearby.

"Are you sure?"  I asked.  "That's a a bit full on."

"But we can do what we want and we should get better weather there."

"And what you want is sex on the beach, with an audience?"

"Let's just see what happens."

So we booked it.

We read up on it, we knew what to expect, but it was still a shock to see people sucking and fucking pretty much when and where they fancied.  People were naked everywhere, but the sex was restricted to the dunes area.  As in Brittany, there were more men than women.

As far as we could tell all the women were accompanied by a male partner, but there were one or two prepared to take on all comers.  During our two week stay, we saw one mature woman fucked from behind by at least six of the men, and witnessed our first bukkake as another woman lay on the hot sand masturbating while anybody who wanted to, wanked themselves off onto her body.  But we didn't spend all the time on the beach, so there may have been more.

Much more common was couples having it off in the dunes.  If people wanted to watch, that was their business, nobody seemed to mind.  Our first morning was spent getting the lay of the land and enjoying the pleasure of skinny dipping.  In the dune area, beach tents seemed de rigueur.  After lunch, we bought a tent.  It was ideal, shelter from the sun and the wind and it had a large apron so that you didn't have to lie on sand.  We found a spot, put up our tent and just chilled out.

Again Jen flaunted her nudity, unattached males observing and hoping for an invitation, which they didn't get.  My job was to keep her well oiled, partly to protect against the fierce sun, but mainly as part of her newly discovered exhibitionism.  She had had all her boy hair lasered off, or whatever they do.

At Jen's insistence, I had shaved my pubes.  It certainly made my cock look bigger, but my hands on her oily naked flesh meant a permanent hard on for me and no way of hiding it.  Jen was highly aroused, not only by my ministrations, but by the small audience that had gathered to watch.  Her nipples were erect and her cunt was the only part of her that was not in need of additional lubrication.

Mostly, the spectators were the single predatory males, but there were also two accompanied females.  Most of the men were openly wanking.  Not a public hair among them.  I finished the oiling and rolled onto my back, my cock proudly on display.  When we embarked on this nudism thing, I had been very self-conscious about letting it all hang out, partly because I was aware that for much of the time, it would not be hanging.  But to my surprise, I was enjoying it.  Compared to the other males, I had nothing to be ashamed of.

Jen, eyes hidden by her oversized sunglasses, feigning sleep, raised one knee and allowed her legs to part, giving the onlookers a full view right up her cunt.  It was too much for one of the watchers, he grunted as he shot his spunk onto the sand.  He wandered off.

Jen was not asleep, seeing the man shooting his load was the final straw, she was in serious need of fucking.  Right now.  She straddled me and impaled herself on my rigid cock.  We were deep inside the tent, but the watchers still had a good view from behind as she began to ride me.  I held on her hips, she was mauling her tits.

She fucked me at first, raising and lowering herself on my pole.  I was almost incidental, just something to rub herself off against and that's exactly what she did, coming very quickly.  Only when she slumped forward, oily tits pressing against my chest, was I able to take control.  Taking a firm grip of her arse, I rammed up into her, desperate for my own release.

Which was not long coming.  Spurt after spurt of high pressure spunk erupted into Jen's cunt.  She stayed mounted until she felt me soften inside her, then rolled away.  A couple of the more pushy wankers took a step forward, presumably hoping for some of what I had just enjoyed.  I waved them away.  Our little group of watchers dispersed.

We decided that we had had enough.  Enough sun, enough of the sand that was sticking to our oily, sweaty bodies, enough performing.  We packed up our kit and left.  Jen went straight to the shower, I went onto our balcony to sort out our beach paraphernalia  then took my turn in the shower.

Despite the numerous application of sun tan oil, we had both caught the sun.  Jen applied soothing cream to my burnt bits, then I returned the favour.

"Well," I asked.  "Did you enjoy being fucked before an audience?"

"It was amazing.  All those men wanking as they watched."

She paused, then said;

"I want more.  Fuck me again."

I looked over each shoulder, then teased;

"Without the audience?"

She glowered;

"Just fuck me you bastard, I need your cock inside me."

"Sorry," I said.  "It's out of fuel."

"Liar."

"No really, it needs priming.  Suck it."

She rolled over and went to take it.

"Not like that," I growled.  "On you knees like a whore."

It was one of our sex games, I was the client, she was the cheap whore, sucking me off in a back alley.  She sucked.  The feel of her soft lips on my tender cock was wonderful.  I was not out of fuel, far from it.  Before long I had to stop her.  I adore being sucked off, but I wanted to fuck as much as she did.

"That's enough,"I barked.  "Get on the bed, on your back, feet in the air."

She complied.  Her cunt gaped invitingly, glistening with her juice, good enough to eat.

"Tongue or cock."

I demanded, knowing what the answer would be.

"Tongue first, but I want your spunk in my cunt."

I feasted on the luscious pink flesh, drinking from her cup, avoiding her erect, quivering clit until I had drunk enough.  Then I went for the pearl in her oyster.  Her orgasm was almost instantaneous.  I scrambled up, desperate to fill her needy cunt with my equally needy cock.  She came again as I slid into her and again as I frantically fucked her.  Unable to hold back, I pumped my spunk into her clasping cunt.

I had never known her to come so many times in such rapid succession, her discovery of exhibitionism had turned her into a she devil.

We decided to avoid the beach the next day, there is a lot more to Gran Canaria than nude beaches.  In fact it was two days after our debut that we returned.  We staked our claim on a spot not far from previously, then wandered hand in hand, looking for a bit of voyeuristic fun.  There were several amorous couples performing, complete with mainly Male audiences.  But the biggest crowd was for a mature, big titted woman who had made herself available to all comers, provided that condoms were used.  We watched her fucked from behind several times, her big tits flailing as they rammed her.

Jen had decided what our own next performance was going to be.  We returned to our tent and just chilled for a while, then we started kissing and cuddling.  Sure enough, a small crowd gathered.  Jen took hold of my erect cock, pulling my foreskin back to reveal my purple plum.  She moved down my body, ran her tongue around the head and then sucked it into her mouth.  The watchers wanked.

Somehow, Jen always knows when I'm about to come.  This was no exception, she removed her mouth and finished me off by hand, making sure that my cannon was pointed straight up when it went off.  A series of powerful sports shot straight up, then fell back onto my naked skin.  There were gasps and appreciative mumblings from our audience.

My part of the performance was over.  Jen rolled onto her back, took her left tit into her right hand and began to rub her oily clit with the fingers of her left.  There were more murders from the spectators.  I raised myself onto one elbow to watch the show.  This was a rare treat, Jen needs a great deal of persuading to masturbate just for my pleasure, now she was wanking for the entertainment of strangers.

My cock was back to attention, I could probably have brought myself off again as I watched, but I didn't touch it.  My second coming would be in the privacy of our own room, in or on my lovely sexy wife.  Some of our admirers , those without the luxury of a beautiful woman to receive their gift, shot their liquid appreciation onto the sand.

Jen climaxed noisily.  The show was over.

Variations of our performance were repeated several times during our stay, sometimes fucking, sometimes sucking, sometimes masturbating, sometimes masturbating each other.  By the time we flew home, we were seasoned exhibitionists.
