Hi, my wife and I had been married for around 15 years when this happened to us. Our friend, overtly gay and a lovely bloke, came over for an afternoon one winters day that turned into an overnight stay due to seriously foul weather that would have been dangerous for him to drive home in the dark, wind and sleet.

Now you perhaps need to know that we had had many threesomes - all MMF - before this event and we were both long-time naturists, so we were comfortable with social and sexual nudity around other people. Our friend was happy being naked, but hadn't gone the naturist route, just solo in woodlands or on beaches with on-one else around.

To cut to the chase, having made the decision for him to stay over, we opened a couple of bottles of wine and had a few snacks and eventually the conversation turned to sexual events we had all experienced. It turns out he had never had sex with a woman and spent most of his energy on either wanking or sucking off his partners. We, in turn, told him (it's the wine doing the talking) of some of our adventures and it became obvious we were all getting a little turned on.

Back in those days, VCR's were the entertainment of choice other than straight TV shows, and we had a few good quality porn videos, so I decided to put one on, but said we'd watch it once we were all ready for bed. That was surprisingly easy, as he had no pyjamas and though I slept naked, my wife preferred to wear sexy lingerie to bed, so she came down in a black see-through teddy, with her tits clearly on show through the thin material, and her completely shaven fanny also clearly visible to us both. By now we were on the third bottle of wine, so everyone was 'relaxed' shall we say?

Our friend and I were both slim, he a little shorter than myself, my wife was only just over 5ft and definitely on the petite side of life, being a size 8 with perfect firm tits and an arse to die for and did I mention a completely shaved fanny? Anyway, all seated on the sofa with her between us I hit the start button on the video.

The film was one of our favourites, a MMF threesome with a seriously sexy female and - so my wife said - even sexier males, though I have to admit they did nothing for me other than I really enjoy watching huge cocks entering cunts and asses and the pleasure they bring.

Our friend, with two big cocks on screen, and my now very rigid one nearby, couldn't hide his own erection, or that he was gently, discreetly, trying to stroke it. With my wife sat between us, it didn't take many seconds before she saw what we were both doing, and being the star performer I knew her to be, she took over handling both our cocks. This was a first for our friend, as he later said he had never had any sexual contact with a woman before. So, this goes on very nicely for about 20 minutes, she gently teasing us both with her hands, and myself kissing her breasts and tweaking her nipples after I had eased the teddy off her shoulders. Eventually I managed to get the damned thing over her hips and then she was completely naked, as we were also.

By this point, I wanted to lick her clit so slid off the sofa onto the floor whereupon she opened her legs for me to get my tongue onto that gorgeous cunt and clit, licking it and sucking the hood into my mouth with my wife making all sorts of very happy noises as I did so. She had been concentrating her efforts on wanking our friend, but now told him she wanted to suck his cock, uncut and about 6 inches of very hard prick. Not giving him the opportunity to say no, she leant over and took him into her mouth, with him looking quite shocked at the experience. That didn't last long, as she is an expert at oral sex, so had him moaning in pleasure in just a few seconds - well lets face it, having someone suck you off is brilliant, and I've since learnt it doesn't much matter who owns the mouth doing the job!!

So while she is sucking and wanking him, I inserted a finger into her anus as I continued to lick her cunt, she managed to cry out that it felt fantastic, even with a mouth full of rigid cock!! Continuing on like this for a few more minutes, I suggested we all move onto the floor to make ourselves more comfortable. At this point I really wanted to fuck her, and she lay down on her back with legs wide open. Our friend was looking at my cock and, a first for me, he reached out to hold it, gently wanking me as I put the tip of it into her cunt. Thankfully the wine had its effect of desensitising my cock, and our friends too, so there was little chance of anyone coming too quickly. As I pushed into her further, another first, our friend reached behind me and was fondling my arse and ball sack which is a different, but exciting, sensation. Slowly fucking my wife, she closed her legs so mine were outside hers, leaving my arse more exposed to the hands of our friend, which was again a first as he moved behind me and started to play with my anus. A short while later I felt his finger trying to enter my arse and to this day I don't know how it happened but he managed to get it into me and pushed it all the way up the full length of his finger - all whilst I was still fucking my wife.

I hadn't ever thought I might enjoy it - but by heck it felt good. He then pushed two fingers into my wife's cunt while I was fucking her, but didn't leave them there for many seconds. The next thing I knew, not one, but two fingers are in my arse. Slightly painful, but very interesting. We three continued like this for a few more minutes, me fucking my wife while my arse was being fingered and him wanking himself with his other hand. After a while, he moved back behind me taking his fingers out of my arse, and I felt his cock at the entrance to my arse as he rubbed himself up and down along my bum crack. With my arse opened by his fingers, he managed to get the head of this cock into me, so as I pulled out of my wife, so I pushed myself onto his cock, eventually, painfully at first, I had all of him in me.

I was fucking and being fucked at the same time - a unique experience for me and one I repeated a few times afterwards.

With all of us busy being fucked, or fucking, we didn't last too much longer and my wife was the first to come - she said it was so erotic seeing and feeling me being fucked - that she couldn't last any longer and came quite noisily with me following on only a minute later as I emptied myself into her hot cunt. Our friend didn't take much longer either, as he felt me ejaculating into my wife, he experienced his own come, and sent his seed into my previously virgin arse.

We were all both shocked and surprised at how the evening panned out, instead of the spare room we went to bed together. I woke to find myself being sucked back to life by our friend, and my wife wanking herself and him at the same time, and so the morning began in a very relaxed and pleasant manner. We all stayed naked until after lunch when, with the weather much improved, he left for home.

We never did repeat this with him, though I have wanked with him and been sucked off by him since that evening. Now, unfortunately, we live nearly 500 miles apart, we're all a lot older and don't get the chance to indulge any more. Shame really.
