We met when we were 18 and married at 21. She was gorgeous - pretty face and slim with small tits and a full bush - the normal style at that time. Never flirty or sexy in public, people could easily think she was shy and frigid. After years of persuasion we went to a nudist beach in England. It was such a turn-on having her nude in public even though she kept her legs tightly together and nothing was on show. She did it to keep me happy but did not enjoy it.
At the time we lived close to a naturist club with a clubhouse, bar, swimming pool and nice grounds. It was risky, but she came for a trial visit and we joined. The place was a genuine naturist club. Everyone was well behaved and although everyone was naked it was not sexy. It was going very well until our 3rd visit when we met a young guy who worked in the same office as my wife. She was embarrassed about him seeing her nude and worried by what he might say to her colleagues, especially as she had created an image of being superior and untouchable. She was beyond furious with me and said I would pay for forcing her into this situation.
The next weekend we went to the club. She stripped to reveal her new closely trimmed pussy - with her pink slit on view for all to see. I was shocked and initially really pleased. Her behaviour was transformed. She played volleyball, walked around getting to know the members, and took every opportunity to display herself in a provocative manner. When she sat on a chair her legs seemed to automatically move apart. While sunbathing she made sure the rays reached parts that had never seen daylight. Quickly she became popular with the men, and everyone noticed the dramatic change in her behaviour. Even though she totally ignored me, I was always on the brink of an erection watching her flirt with her new admirers. However, when we came home she wouldn't touch me, and sex was not on the agenda.
The next weekend she went to the club alone in the morning - when I joined her in the afternoon she was in the bar with Steve. She told him that she was sexually inexperienced and wanted him to fuck her, telling him he could do anything he wanted. His cock was much thicker and longer than mine - she wrapped her hand around it and said "I can't wait to feel that inside me". They left together and I sat there, obviously I had been replaced. At 01.30 she got home and told me he had fucked her long and hard that it was fantastic. While she was telling me exactly what he did, my cock was getting hard. This annoyed her and she moved to the spare room saying it was obvious that I still had a lot to learn.
My wife continued to have sex with Steve, without telling me any of the detail. I stopped visiting the club because she would really show off with Steve and although the other members were very nice, some were laughing at me.
We were now living almost separate lives, and for me it was no fun at all.
She had joined an evening art class for portraiture - she was quite good. One Saturday she asked me to pose nude for her in our own living room. I was happy to do it, and hopeful that it might lead to us having sex again. She arranged my pose on a high stool -- making sure that my cock and balls were on full display. After about 15 minutes the doorbell rang and, and 5 women walked in with their sketch pads and joined the "class". Saying it was brave of me to agree to pose for them -- I had been tricked, and I would look like a complete wimp if I tried to back-out.
I knew all the women, and I knew why my wife had chosen them. There was Katie - her best friend. Jane, in her 20's who worked in our local pub. Sheila - a very popular woman from the naturist club who knew everyone. Carol, a girl of nineteen who worked in my office, and Marie, a neighbour in her 50's who was well known as a gossip who found it impossible to keep anything secret. Carol and Marie didn't know that I would nude, and both started laughing at me.
They drew for around 20 minutes and said I should take a break and look at the work. I was asked to resume the pose and work continued. My wife started some friendly chat and said that I had forced her to strip on a nudist beach and join a Naturist club, and that I got-off forcing her to be nude in public. Understandably they were all on her side, and I was some kind of pervert. She went into some detail and then told everyone that I got excited when she talked about Steve fucking her. Sheila mentioned that she was a naturist and Steve had the biggest cock she had ever seen. Everyone laughed. At this point I started to get an erection and I couldn't stop it. Carol was a talented artist and achieved a very good likeness - asked if I could hold the pose so she could show it to her friends at the office next week. Everyone laughed again. Marie said the only man she had seen with an erection was her husband, and she would love to see me getting a hand-job.
Every one of them said yes please - and my wife quickly obliged.
I had to sit for another 15 minutes with a drip of cum on the end of my cock. They all thanked her for organising the class and there was a lot of girly laughter as they left the house. From now on, most of the people I knew would hear about this. When I went to the pub, the naturist club, the office - and even in my own street - everyone would know. She said that her original plan was just to have me nude and embarrassed, and reminded me that this whole thing started when she was exposed to her work colleague at the club. The hand-job was never planned, but she was really pleased with the way it turned out.
The affair with Steve continued through the winter and spring. I heard from a friend that she had a reputation for flirting with the men - she had become a very sexy "prick-teaser". Some of the wives were not happy with her behaviour. I also heard that her relationship with Steve was going downhill. In the late spring Steve had a party. There were around 20 people there with only three women - including my wife.
The party started with drinks and Steve made an announcement - that his girlfriend (my wife) had come to him for sex and would do anything he wanted. He said that she had become a total prick-teaser, showing off to all the men - showing them what they couldn't have. She is obviously an exhibitionist, so I am going to take her hobby one step further. Most people here have seen her nude, but have no idea how sexy she can be, so if anyone is likely to be offended, they should leave now. Nobody left. Steve said - I know you love it, so take your dress off and let us all look at you. She didn't move - so Steve said - let's help her. She was quickly stripped and groped, Her young work colleague ripped her nickers off and she was totally naked in seconds. Now she realised she couldn't stop what was happening she didn't resist - she cooperated opening her legs and posing in the most provocative way possible - and making encouraging comments to the men groping her.
The two women were nowhere near as attractive as my wife, they were jealous of her, and annoyed by her flirty behaviour. They wanted to watch Steve give her the fucking she deserved, and they wanted to see her humiliated and tearful.
There were also two male friends of ours from the tennis club - we had socialised with them in the past and they knew we had sort of broken up, but because my wife had been so prim & proper in the past, they never expected to see her like this. They had never even seen her in sexy clothes. The rest of the crowd was mostly from the naturist club, plus a couple of Steve's friends she didn't know, and a married neighbour who we saw frequently - he had never seen my wife nude and thought we were a normal respectable couple.
