The first time, when I discovered my wife having sex with another man, was one hell of a shock. I thought my world had ended, I thought we were happy with our middle-aged existence, but I subsequently discovered my wife wanted more. I had been away on business for the week, but had decided to come home a day early on the Thursday evening. We live within walking distance of the local railway station so, when I go away on business, I prefer to use the trains as I can do some work rather than sit for hours on the motorway. I arrived home just after 9.00 pm, both our cars were on the driveway, and there are always lots of other cars parked in the street, commuters parking for the station. When I opened the front door, there was music playing in the front room, I poked my head round the door but there was nobody there, only odd items of clothing lying about, which I thought was strange. I had just noticed there was a mixture of men’s as well as ladies clothing when I heard a noise coming from upstairs, it sounded like someone having sex. I crept upstairs, I’m not sure why but perhaps it was because I have always thought that having sex is a private moment, not to be interrupted. When I got to the landing, our bedroom door was half open and I could see my wife, Tina, was on the bed being vigorously fucked from behind by a man. He was totally naked, but she still had on stockings, suspender belt and high-heeled shoes. She was in the throws of an orgasm, gasping and calling out encouragement to him to “fuck me …… fuck me harder …… that’s it make me cum …… fuck me you bastard”. He had reached round with his hand, and I assume he was stimulating her clitoris as she screamed “oh yeeesss”. I just felt a mad panic, my beautiful wife of over 25 years was having sex with another man, I simply had to get out of there before I burst. I sneaked back downstairs, picking up my suitcase and briefcase which I had left in the hall, I don’t think they would have heard me opening and closing the front door, they were making so much noise, and I went off into the night. I wandered the streets for a while, not knowing what to do, but I eventually decided to get a room at the Travelodge on the other side of town. I lay awake for much of the night, my mind reeling from what I had seen. I did get some sleep in the early hours and, when I finally awoke, I decided to spend the day at the local library doing the reports from my week’s work to distract my mind. I suppose I should have started with pen pictures of my wife and me. I am Adrian, 58 years of age, and I work as a consulting engineer, a partner in a small firm based in our town. I’m not sure how to describe myself physically, but I think I am pretty average. My wife, Tina, is a bit younger than me at 51, and she carries her age a lot better than I do, she goes to the gym regularly and eats all the right things to stay slim and fit. Tina works as a receptionist in a GP surgery. We have two children, the younger one in the middle of a university course and the elder now out in the big wide world of work, both of them live some distance from us. I think I had assumed that, having done our bit to further the population, sex was a thing of the past, and we were drifting towards a sexless old age. When I came home again on the Friday evening, I tried to act normally but it was difficult because I kept remembering the sight of my wife being fucked in our bed, and I have to say the thought raised my erection from time to time. On the Sunday evening, Tina asked me if I had come home early on Thursday and, when I looked at her quizzically, she said that I had left my briefcase open in the study and she had seen the Travelodge invoice inside. After a long silence, I told her that I had seen her in our bed being fucked by another man, which left her wondering what to say. Eventually, she admitted that she had been having sex with other men for over a year. It had started with a quick fumble at the back of a pub carpark with a guy she met on a girlie night out, which had gone too far and he had fucked her from behind over the boot of a car. She said she found making love to me was ‘slow’ and she had so enjoyed the excitement of fucking another guy, she had joined a swingers website, where she had a never-ending supply of men to excite her. She said she always used condoms, quite apart from the risk of infection, she was not totally convinced she could not get pregnant. She said that she usually chose married men, as they were only there for the sex and would not get too ‘clingy’ and they were usually prepared to pay for a hotel room. Last week had been the first time she had done it at our house and it had been a mistake because the guy appeared to think he could now get his feet under the table. She said the sex had been amazing, but she was going to tell him she didn’t want to see him again. By the time I came home from work on the Monday evening, I think I had got my head around the situation, although it occurred to me that my wife had not apologised at all. When I kissed Tina in the hall, I gave her a special hug, perhaps to signify that our marriage was not broken. She said she had not started cooking the evening meal yet as she wanted me to make love to her first. I was a bit surprised as we had not made love for perhaps a fortnight, and it had never been as spontaneous as that ever. We rushed upstairs like two excited youngsters and fell upon each other as soon as we got into the bedroom. Tina insisted on keeping her stockings and suspenders on but, against her wishes, I tore her thong off so I could get my tongue deep into her pussy. I had the snip after our children were born so we don’t have to worry about protection and I must admit that bathing her cervix with my sperm seemed like the best way of re-claiming my wife. As we lay side by side enjoying the afterglow, Tina said “wow, you were really passionate tonight, have I found a way to provoke you”. She said that, when she found the Travelodge invoice, she thought I was having an affair with someone in the office, but was relieved I was not. I asked if having sex with other men was something she wanted to continue, and she looked at me pleadingly. So, I have effectively agreed that Tina can carry on seeing other men for sex. I have offered to help her vet their online profiles and also be involved in the emails that precede meeting them, but she insists she does not want me to be involved. She usually insists on a comfortable hotel room although a couple of times she was so attracted to a man, that she fucked him in the back of his car in a layby on the first date. None of them seem to last very long though, having had several dates with a guy, she wants to move on, even though she has told me the sex with him was fantastic. No, I don’t understand women either. Our sex life has picked up enormously. Tina usually tells me when she is due to meet one of her dates and sitting at home, or wherever I may be, knowing that she is being fucked (Tina always refers to it as her fucking them) is so arousing for me too. If I am at home, I am usually feeling very horny when she comes home, and I want to make love to her there and then. I can usually tell if he has a big cock, because my wife’s pussy will be ‘slack’ and ‘stretched’. Plunging my tongue into her wrecked cunt, where her lips just open wide to my touch feels very erotic. Sadly, I don’t get to enjoy sloppy seconds as Tina is totally adamant that I will be the only person to cum inside her. When her pussy has clearly been heavily abused by a large cock and she is very red and sore, I have wondered whether she might prefer anal penetration, but that has always been a ‘no go area’ throughout our marriage, so I have decided I must wait for an invitation from her. Tina has asked me from time to time whether I wanted to join her, swinging with another couple as she finds the thought of seeing me with another woman quite erotic. I told her I was not so enthusiastic, but I would think about it. She then said she was slightly attracted to the thought of her having sex with another woman, but therein lies another tale.
