My wife and I have been swinging for many years and we have been to many sex parties in houses and clubs all over UK and Europe. We are very experienced and these days we often do separate room sex as my wife likes to be fucked by young men half her age and does not want a husband around that makes her feel older. At most clubs and parties these days my wife gets a good fuck from around four to six men each time and we come home very happy. She is a size 10 lady, 36D tits and over 65 years old - she is regularly fucked by men in their 30's who chat her up than take her off upstairs or to a playroom for a good shag. We used to meet only couples and go to couples clubs and parties but over time tastes change and now my wife is into being gangbanged and normal party sex is for a spitroast as a minimum. We have been going to a club in Holland for many years and we know the hosts very well. They sent us an e-mail asking if we would be interested in an invite only gangbang night a couple of months ago. All the men would be vetted and under 40 and the couples had to follow special house rules for the night - these included strict dress code and behavior expected. My wife accepted (she had the rules known to herself) and we went off to Schipol airport on the appointed day - a Friday evening. I was entranced watching my wife get ready - hair, nails, face etc and then put on stockings and suspender belt and nothing else. At 8pm we got a call to say the taxi had arrived and she put on a coat and off we went. normally we both get in the back but this time I got in the back and she got in the front and as soon as we left the hotel area she opened her coat. I could see from the rear that the taxi driver was having a feel of her tits and cunt as we drove (not a safe practice I thought). Anyway we arrived safely at the club and went inside (the taxi was free). We went to the changing room and the coat was put away and I stripped to only wear a towel. At this point she told me that as a husband I was only allowed to watch and not join in, although I could have sex with any of the pother married women there. By this she explained, I could have sex with whoever I wanted as the women there could not say 'No' to anyone. We went to the bar and had a nice glass of Pinot Grigio, followed by another. There were about thirty men there by 9pm and about five married women. One women went into the lounge area next to the bar and was surrounded by men - she was naked and all five women wore very little, the common thing being that their tits and cunt were on show - a house rule for the special night. I went to have a look and saw her suck cock and take it up her cunt on the sofa and when I looked back at the bar I could see a man sucking my wife's tits and another fingering her while she was drinking her wine. Another glass appeared and the scene carried on - her having a rink and two man chatting whilst having a good feel of what she had to offer for sex. I went to have a look at the lady having sex and when I looked back at the bar my wife had gone. I went to the playroom area (normally I stay in the playroom with my wife and masturbate while men fuck her just so she knows she is safe) but this time all the playroom doors were open and available for use. I went into two and saw a couple of women getting fucked and cock sucking - the normal thing is sex clubs. Then I went into the third one and saw four men around a women whose stocking clad legs were in the air. This was my wife getting fucked by someone she had just met at the bar. She had cock in her mouth and two men were standing having a wank just waiting their turn. As this was the first time we had done this I stayed to make sure she was OK. However what I heard was "Who's next?". My wife was so brazen - the occasion had engulfed her and she was up for anything. I saw the men fuck her in turn and for the first time I saw a man put his cock up my wife's arse - she is used to anal sex as we do it all the time but I had never seen anyone else do it to her. After all four had fucked her everyone got up and the men escorted her back to the bar where drinks were ordered for her. She enjoyed another glass of wine and a very young man (about 40 years her junior)asked her for a dance. She got up and they danced a slow dance holding each other, more like husband and wife than lovers, with him giving her pecks on her cheek and so on. After a while I saw she was holding his cock while dancing and he was just dancing and enjoying. When the music changed she came back to the bar, leading him by his cock and they sat together and finished drinks. After a few soft words off they went to the playroom and I saw her having a one to one fuck with him. As the door was open a number of men went in and then she had a lovely gangbang with five men. She sucked off each man and had his cock up her before they left. A couple of new men replaced two that left and I saw seven men fuck my wife in turn. She looked rally well fucked when I saw her again - I went off and fucked one of the other married sluts and was being sucked of by one near the bar when my wife returned with her hair and tits spunked on. She sat at the bar and a drink was immediately forthcoming by the appreciative management as she had been open to being fucked so often. She has fucked men all our married life but never like this (when we married - a second marriage for us both - she said she needed to fuck men and it was a condition of our marriage that this happened - she fucked four men on our honeymoon with my full blessing just to ensure we were both fully understanding of our marriage arrangement). As she sat there a couple of men came for a tit suck and she just sat drinking while they had a tit reach. She was totally distracted by having a galls of wine - in a way she looked a total slut - my wife with her tits and cunt on show drinking wine with two man sucking her tits and her talking to the barmen as if nothing was happening. I actually spunked in the woman's mouth watching this scene. It was about 11pm by this time. I did approach my wife and she said 'Hello - having a good time?' I told her I had just cum and she said she had cum four times already, her tits and cunt were sore but what a wonderful evening it had been. The club owner came over and said I should not be with my wife but as he had noticed she had fucked lots of men it was OK as long as I made myself scarce soon as other man might want my wife. I got a glass of wine and sat in the lounge area leaving my wife at the bar. All the men appeared have fucked at least one woman and the evening seemed to be getting to calm down. I saw a few men finger my wife at the bar but that was all. Three women were still being gangbanged in the lounge area and I concentrated on these women. When I looked again in the direction of the bar the barman, a big black man, was snogging with my wife. I knew from previous visits staff could not have sex with guests so thought nothing of it. A little later she was gone. I went to the bar a for a re-fill and the black man served me; I then saw my wife on the other side of the bar with his cock in her mouth while he served me, not knowing it was my wife giving him pleasure. As he could not fuck her I saw him fucking her mouth until he grunted and I assumed my wife had accepted his cum down her throat. Anyway she did regain her seat at the bar. Most men were fucked by now but I did witness one man dogging my wife as she stood at the bar with the barmen sucking her tits. however the best bit was to come - we had to leave and the taxi came; this time I had to hold her coat and she got into the front set wearing nothing except the stockings. We drove along like this and I saw her go down on him and she sucked him all the way to the hotel. At the hotel she put on her coat and we went to our room. She then told me it was the bat sex she had ever had. At her age she has had numerous cocks up her and we have been to many parties that turned into orgies so it was uplifting to know she had been treated to the best sex of her life that night. I am married to the wonderful lady but her tits and cunt are hers to do with as she pleases. I can fuck whoever I want at parties/clubs as can she and we have never been unfaithful to each other. In the 14 years we have been married we think 400 men have fucked her, so her cunt is hardly mine. When she wanks, which is often, she always thinks of fucking at least two men at the same time - this gives her multiple orgasms. We go to a sex shop on Oxford Store regularly and she buys gang-bang films regularly to watch and wank to. Anyway the next day she said it was he best sex she ever had and we were going again to the club that night for normal sex. We did and she wore a see though top and a very short skirt with no knickers. It was normal night of sex for us -OI fucked two women and she fucked about six men completely separately without either of us witnessing the other's sexual evening. When we go we now always go as a couples far as the door then as two single persons until we go home - as a single woman in such a club my wife was offered, and accepted, sex with couples and single men. We find that as a single female my wife gets the level of sex she needs - it is not a pleasure for her, it is need that has to be satisfied; my wife is wonderful all the time and it is a small price to pay to take her to places where many men can strip her and do whatever they want with her as she was either born or developed into a sexual submissive before I met her. Giving her access to places where she can be used sexually is part of our marriage and a very successful and happy one it is too.
