We have been going to one particular naturist site for a long time now, sometimes only for a few days, other times for several weeks at a time. As seems to be usual, the kids had forsaken the naturist lifestyle as soon as they hit their 20's, so we found ourselves going alone for the last few years. This has turned out to be rather interesting, as you are about to find out. We had, by now, been enjoying threesomes and moresomes for many years, the vast majority being of myself and S, with additional male company for S, as we are both straight. On this particular occasion, we had been at the site in the south west for over a week, though we knew we had to return home two days later. S and I had been chatting to several people, though there were two guys of our age, mid-forties, who had family due to join them at the weekend. We got along well, drinking and eating together for several meals during the week. On this particular night, they said they were off to a local pub by walking across the fields. S wanted a shower and to stay in for a while, so we said we may meet them later. Eventually, we get into the car, and set off to the same pub. S had decided to wear a simple long button-through dress and tiny white knickers with beach shoes, she looked cool and very sexy. As the "dedicated driver" for the night, I was on soft drinks, and S had several large glasses of wine as well as a couple of Bacardi and Coke's to progress the evening, in the company of our two camp cronies. Progress on to closing time, after much flirting and sexual inuendo, we offered the guys a lift back to the site. At the car, D got into the front with me, S and B in the back As we were all regular naturists, I jokingly suggested we all strip off, and drive back naked - to much amusement from the passengers. As no-one started to strip, I moved off, and went at a sedate pace through the town, then out into the countryside. At this point, I realised something was happening, as S had gone quiet. A glance in the rear view mirror showed her busy kissing B, with hands everywhere. It is a bit difficult driving, knowing your wife is in the early stages of seduction! I still don't know if it was B or S who started this, neither can remember! We hadn't gone much further, when I felt S moving around on the back seat as B removed her knickers, then her dress! D was doing his best to provide a running commentry, but was rather too excited to remember to talk some of the time - can't say I blame him! As there are children on the site, I thought it better to stop off before we got back, as I had no intention of waking the site with S's panting, gasping and screaming! I found a pull-in by the entrance to a field, and got out with D to watch the scene unfolding on the back seat of the car. It didn't take more than a nano-second for both of us to get rampantly rigid, watching S taking B's cock into her mouth and down her throat, as he continued to finger her naked and well trimmed cunt. This continued for some time, as both D and I had to stand behind the car when others passed us in the lane, so I suggested we all got out of sight by going into the field. I popped the boot, got the carpet out and put it on the ground. S lay down on this, as B got between her legs and licked / sucked her for all he was worth. D and I knelt either side and S played with our cocks, wanking and sucking us while we played with her tits and legs, holding her open and high for D to continue with his tongue. Eventually, S had her first climax, and B took the opportunity to slip his cock into her very well lubricated fanny. They fucked for quite a while - obviously just enough beer to de-sensitise his cock - until, after about 20 minutes, B came deep inside her cunt, with a groan that could be heard in the next county! Not to be outdone, D immediately climbed onto S and fucked like a rabbit for only a few minutes, before adding his come to that of B inside her now slightly loose cunt. I rolled S over, onto her tummy, so that I could enter her from behind. She raised her beautiful, pert backside up into the air to meet my cock, which that night would have pierced steel, I was so excited. We fucked doggy-style for some minutes, before S slowly slipped down, as I continued to push slowly into and ease out of her now very slippery cunt. This for me was the best ever - seeing a live sex show immediately before fucking my amazing wife, with a warm, wet cunt to play in, and feeling those superb buttocks rubbing underneath my tummy. Wonderful! I had one hand under her, feeling her left tit, the other hand under tummy playing with her clit, and my cock into her cunt from the rear, now pounding away on the short strokes! As I came, I realised the others were still watching, and getting harder again. We all threw our clothes into the car, put the carpet into the boot, and drove back to the site. Later, as all the other adults left the camp fire area, leaving only S, myself and D and B, we started to play again. Over the back of some of the seats, B took S again, doggy style, while B and I watched and wanked, again all of us naked and fucking by firelight. We can heartily recommend it - try it yourselves you could be surprised how much fun it is. As time has gone on, S and I now find ourselves older, heavier, but at least in S's case, just as randy and ever willing to fuck. Just goes to show that even those of us in our early 50's still have a sex life, as S proved recently, walking naked down a lay-by to fuck a lorry driver in his cab! I may pass on this nugget of information if you are interested. As an afterthought, some of you have kindly replied to these remeniscences by suggesting a meeting - very kind, but we no longer live in the Hampshire area. We have moved up country to the west of Wolverhampton. Sorry! To those in the area now, invites welcomed.
