My wife was very attractive and sexy. We married young and before long we had children. I loved looking at her sexy body. I talked her into wearing lots of sexy clothes. When we went out, she never wore a bra and often semi sheer blouses. It was also a time of short skirts and dresses and for me she wore the shortest she could get away with. It was also a time of sheer bikini panties. As time went on, I talked her into situations where other men could see her safely. Gradually I talked her into "accidentally" showing off more and letting other men see her. Often for fun we would go to a shopping mall with her wearing a short skirt and she would shop on her own and when a man was watching her, she would lean over to look at something and give him a peek. I would watch from a position where I could watch also. As my wife got comfortable with this and turned on by it, we developed a method where we would go into a store such as a book shop. She would find an aisle with a man in it and look at book in the same aisle. Naturally the man would notice her and she would ignore him but would lean over a little getting his attention. I would enter the aisle from the other end and look at books. I liked to see exactly what the other men would see. Usually the guy would be discreetly watching her rather than the books. When my wife knew she had his attention, she would lean over farther and let her panties show. Many of the men would actually stoop down so they would be lower and see more. When they did this my wife would reward them by leaning over farther and usually they would get a good look at her backside through the sheer panties. After a few minutes she often would move to another aisle and about half of the time the man would find himself in the same aisle behind her a few minutes later. I got very turned on looking at her and seeing the men look at her. We did this almost every weekend. One day she was doing this in a bookstore and there was a good-looking young man our age who really looked her over and actually followed her around the store. I was turned on by his attention and my wife was also and gave him an extra show. After we left the bookstore, we walked the mall and I went to the restroom and she sat by a fountain in the centre of the mall. When I came back, I saw that the guy was sitting next to her talking to her. When I came up, he introduced himself and my wife said he had asked her if we were swingers. She said she had told him no, which was the truth, but it was obvious that what we were doing was on purpose. He was very friendly and we hit it off right away. He was brave enough to tell us how much he liked looking at her and thought what we were doing was fun. He then asked what we were going to do next. We didn't really have any plans but I said we were thinking of going to a movie and he asked which one. We hadn't decided and he suggested that maybe we could all go together since he didn't have any plans. We were all turned on so it may have clouded our judgement but xxx movies were popular and this was before internet etc. He asked if we ever had thought about going to one of them. We had but were too chicken. He suggested that we all go together. I thought that might be a good idea because it would be safer with 3 of us. The theatre was nearby and was a good one, not a dump. We agreed to meet him there and on the way my wife and I talked and we both decided it might be fun to see the movie. It helped that he was a nice guy and I know my wife found him attractive. I think he was surprised that we actually showed up. Once in the movie my wife sat in between us. It was the first xxx movie we had ever seen and the sight of seeing beautiful sexy people having sex was erotic and my wife was obvious enjoying it. Her dress was very short and when she was sitting down it was only a few inches below her pussy. Soon I reached over and began caressing her leg which was very visible in the movie light. Her leg was smooth and very sexy. I saw him looking at me caressing her. I leaned over and told her to take his hand and to put it on her other leg. To my surprise she actually did it and soon we were both caressing her legs. This combined with what she was seeing on the screen got her really going. I noticed that gradually she was opening her legs slightly and I caressed the inside of her thighs and soon he was doing the same with the other leg. Soon I reached up and rubbed her pussy thru her panties. She responded obviously and after a minute I moved my hand and he did what I had done. She was very turned on when he touched her pussy. By then I was not thinking about all the consequence since we were all having a good time. I whispered to her to slip her panties off and I was very surprised when she actually did it. I slipped her panties into my pocket. I watched and he moved his hand up and began touching her naked pussy. He and I took turns touching her and soon we were taking turns putting our fingers in her. It made me very hard taking turns with him and seeing how turned on she was. I couldn't stop myself and I took her hand and put it on my cock which she squeezed thru my pants. I whispered to her to do the same with him and she did. She was so turned on that she laid her head back on the seat with her legs were apart and she had a cock in each hand. About then the movie ended and we had to leave. Once out of the theatre, we were walking to our car. Once we got to our car he asked if he could talk to us in the car. So, he and I got into the front seat and my wife got into the back. He was telling us how much he enjoyed it and how sexy it all was and how sexy my wife was. I was in uncharted territory here. My wife and I had never talked about this possibility or even taking it past her just showing off and now we had gone way past that. I was thinking that maybe this was enough for now and was trying to think out to get out of it. He was looking over the backseat and telling my wife how sexy she was and how good she felt and how beautiful she was. Then to my surprise she asked him if he would like to get in the backseat with her. I was surprised by this invitation and wasn't sure I wanted to go that far, but didn't know what to say or what would happen if I cancelled my wife's invitation. The guy didn't really ask me if it was ok. He just popped out of the car and got into the back. As soon as he was with her, he was kissing her and feeling her breast thru her dress. I turned around so I could see what was going on. We were parked near a street light so there was quite a bit of light in the car. I saw the flash of her bare legs as he pulled her skirt up and she laid back. I was holding my breath as I saw his fingers go into her pussy. I found myself very turned on watching this and seeing how turned on my wife was. I thought that this was just going to be a heavy touching session when I saw my wife reach up and unbuckle his pants. That's all it took and he just struggled out of his pants and was naked from the waist down and my wife's skirt was up around her waist. About this time, it really sunk into me that he was going to fuck her. A part of me wanted to stop it and another part wanted to see it. Things were happening fast and I was speechless. I looked at my wife's face and knew there was no turning back. Then I saw her move her legs farther apart and put one on either side of him. He moved up and I got a glimpse of his cock hard pushing at her. For a moment I thought he wouldn't be able to get it in in the cramped back seat. Then she reached down and guided it in and he slipped easily into her. She wrapped around him and obviously climaxed when he put it in. They held still for a long minute and then she relaxed and he began moving in her. From the front seat, I saw her legs around him and his arse moving up and down as he fucked her. I was embarrassed to admit to myself that I found his arse moving up and down and knowing his cock was going in and out of her to be very hot. In the position they were in he was able to take her vigorously. She was encouraging him and was fucking back at him almost as hard as he was fucking her. When he came he moaned and thrust very deep into her and she cried out also obviously climaxing also. They stayed locked like that for it seemed like a long time and I was just sitting there with a hard on. As soon as he pulled out, he got his pants on and my wife sat up. He thanked us and got out and went to his car and my wife moved up front. Luckily, we lived close to the theatre and we were home in less than 10 minutes. We didn't say much on the way home but as soon as I got into the house I was kissing and touching her. By now she was having second thoughts since we had never talked about her actually having sex with another man. She was worried that she had screwed up by getting so turned on. She was relieved when I assured her that it was ok and that it turned me on a lot watching her. I couldn't wait to get her into bed and I was hard just thinking about it. I was a little startled when I spread her legs and saw how wet and used her pussy looked. I touched her and she was very, very wet. I didn't wait and I moved over her and my cock slipped easily into her. She was very wet from her juices and I knew she was also very wet from his cum in her. She was silky and the feeling was obviously very different. At first, I thought I should be put off by his cum in her but was surprised to find it turned me on even more. It made me want to claim her back. It didn't take long until I came in her also and she came with me. We were turned on for a couple of weeks by what we had done and I had wished that I had gotten that guy’s name and phone number so we could do it again. My wife was also enthusiastic, she really liked it. She was amazed at my reaction which settled her mind. We decided that we had to find this guy again. My wife and I believed he was perfect. So, we started going back to the book store where we first saw him. We also went to the fountain where she talked to him. We did this for weeks. We even went to the theatre hoping he might go there again. I fingered her like he and I did during the movie. She wanked me as well. This all went on for months and we never saw him again. We gave up and decided we should find someone else. About a week later, my wife and I were walking in a totally different part of the city and we walked past a couple and the wife was pushing a pram. It was him. He smiled because he recognised us as we did him. We sort of followed them and when his wife stooped to do something to the baby in the pram, I walked up to him with a piece of paper with my wife’s name and phone number. I pushed it into his hand and turned and walked away. That evening, he called her. He apologised for leaving in such a hurry as he had wanted to see here again. He could call the next evening at our house when he finished work. Both my wife and I left our work early and she made herself ready for his visit. Within 5 minutes of him arriving, both he and her were naked. He fucked her in our bed and I watched. We had plenty of light and we all enjoyed it. He was soon gone, probably only staying ¾ of and hour as he had to get home. As soon as he left, she and I fucked. Once again, it felt incredible pushing my dick into her silky cum filled pussy. This is getting long so I will finish soon. This went on for 3 years. He would call at every opportunity. I would be there to watch them. I never joined in. I never wanted too and my wife never asked. A few times he had to go away and travel for his job. My wife took time off from her work and travelled to the same place and stayed with him. I did ask to go with her but she wanted to be alone with him. It was always a long wait on my own as she was away for usually 3 days. I had to wait to fuck her as soon as she got home. It was after the time when I asked to go with them, that when he called in next, he had her suck his cock in our front room. They had planned it. As soon as he arrived, he came in and dropped his pants and she knelt in front of him and blew him. He stood and held her head in his hands and sort of fucked her face. This then became a regular thing. It was after about 3 years that she said she wanted children and that she was going off the pill and told me that she was ending it. I was shocked, as I sometimes thought I was losing her. We never had her fucked by anyone else but me until our children were in middle school and we could leave them easily. That’s another story.
