We married young and although I had had a number of relationships my wife hadn't, but I had told her the first time we had sex that I was a virgin. We've been married for 30 years and are in our late forties, the kids have flown the nest and my wife has suddenly developed the urge to have sex with other men - this urge started when I confessed a couple of years ago or so, that I'd had sex with other girls before we'd married. My wife over the last 12 months or so has become firm friend with a women of a similar age at work and we started going out for meals with her friend (Linda) and her husband (Ian) and at Easter went on holiday together. Whilst on holiday (and after a long drinking session) my wife Ian and Linda that she wanted sex with other men. Her friend said that they belonged to an exclusive adult club - essentially a very private swinging club - and would recommened us for membership if we wanted. I talked it over with my wife and we were both interested. We let Ian and Linda know and a week later were told that we'd been accepted and that the following Friday we'd have to attend an initiatian ceremony. On the Thursday night I went out for a drink with Ian as he wanted to explain the initiation. He told me that the main club rule was that both partners had to equally want to join and that as the male partner I had to take a challenge, to which I agreed. The following night we arrived at the club, a large country house just outside Burton-on-Trent, my wife went with Linda to get a drink whilst Ian gave me the guided tour. There were probably about 15 couples in all and although there were plenty of "activity" rooms, none were being used. Ian told me that as it was an initiation night there would be only one main activity that night. By now an hour had passed and Ian took me into a room where I was surprised to find all the women including Linda but not my wife. Ian siad that my challenge was to stay in the room until the main activity had ended, then I could have sex with Linda as this was part of the initiation. Ian then left the room. Along one wall of the room was a long curtain which two of the women drew apart. I was looking through what I guessed to be a two way mirror looking into the adjacent room that had in it a double bed. Standing between the bed and the mirror was my wife blindfolded. Ian then walked into the room and slowly undressed my wife, he then led her to the bed and laid her down on it. He then stripped off and had sex with my wife. As soon as he finished, one of the other men came into the room naked and he to screwed my wife. One after one each of the men entered the room and entered my wife - in all she was screwed anally, vaginally or sucked off 16 different men in just under 90 minutes. After the last man had finished my wife came into the room where I was standing with all the other women. Linda the led me into the room where my wife had been, slowly undressed and then undressed me and told me to screw her whilst everyone else watched which I did. We've been members for a month now and there's a new couple to be initiated next weekend.
