I start with an apology that this letter is rather long but it is important to explain the background in order to appreciate the enormity of the experience we have recently had. I am 39 and my wife of ten years is 37, Sarah is an attractive woman with blonde hair and a size ten figure she has smallish boobs but they have remained firm despite two children. When we first met I had been around the block a few times so to speak! Whilst Sarah had only had one previous boyfriend whom she had slept with but only a couple of times before they split. She was very inexperienced sexually and very shy. We had sex before getting married but it was mostly in my car and on the few occasions we managed to do it in a bed she was too shy to have a light on and was generally uneasy about nudity. Things did improve once we were married and had our own house but it was always pretty conventional and despite me trying to introduce sexy underwear etc it was always an uphill struggle. We once holidayed in Greece and Sarah did sunbathe topless a few times but it was more due to the fact the she looked more conspicuous with her bikini top on than with it removed. I tried to get a photo of her on the beach but I was left in no uncertainty that she did not approve. It was about two years ago things started to change, both our children were at school full time and Sarah had much more time to herself and took a part time job in a office in our local town. She enjoyed the job and became friendly with some of the other girls she worked with, this led to girl’s nights out about once a month or so. Sarah was particularly friendly with one of the other girls called Julia. Julia was slightly younger than Sarah and very attractive with a stunning figure she was also very flirty and dressed sexily with push up bras and figure hugging tops and skirts. I suspected that it was Julia’s influence that led to the change in Sarah. Looking back I suppose the changes in Sarah’s appearance was quite slow, it started with more frequent visits to the hairdressers and this was followed by sexier bras that were padded and her conversion to thongs that seemed to get smaller and smaller. I know its sounds daft but I didn’t really notice until I mentally compared how she looked and dressed now compared to a year ago. The one thing that convinced me that she was becoming a much sexier woman was one night when we were sat in bed chatting. Sarah mentioned that she had just bought a new bikini for our holiday in Italy the following week and had tried it on earlier in the day. The bikini bottoms were in her words a little bit on the skimpy side and her pubic hairs poked out of the sides. Sarah then asked me if I would mind if she shaved down there as no girl wanted to have her pubes on show on the beach. I was not only gob smacked but also highly turned on at the thought of her shaving her pussy. Two days later Sarah was in the shower as I was washing at the hand basin she emerged from the shower razor in hand and asked me what I thought of her reduced amount of pubic hair. I was slightly disappointed to see that she had only removed about two inches either side of her pubic mound and had not touched her actual pussy area. I suggested she try on the bikini bottoms again to see if she had removed enough hair. Fortunately although the top half was fine, around the crutch area you could see hair visible. I suggested that she should shave her entire vagina to totally eliminate the potential hazard. Sarah emerged from the shower again 15 minutes later completely shaven. I struggled to control myself as she looked absolutely fantastic and I could have fucked her there and then. I sensed Sarah felt a little embarrassed at her slit being so exposed so I reassured her that most women shave nowadays and there were health benefits as well as cosmetic ones. Sarah seemed reassured by this and admitted that she felt much cleaner down there minus hair. She did experience some discomfort due to regrowth but I just suggested that she needed to increase the frequency of her shaving and that shaving rash was only temporary until her skin adjusted to the razor. We had a fantastic holiday and had sex more often than I could remember in recent years. I have to say that going down on her shaved pussy was an absolute fantastic experience and Sarah admitted that she came much easier than when she was hairy. A couple of months ago Sarah started to introduce her friend Julia into conversations and I felt she wanted to tell me something but didn’t know where to start, slowly I started to ask probing questions about Julia as I knew she was the instigator of Sarah’s more liberal attitude to sex. Once the ice was broken so to speak Sarah told me that Julia had a very active sex life and although she was in a relationship, her partner not only knew she slept with other men and occasionally women but encouraged her to do so sometimes on her own and on several occasions as part of a threesome. This had totally shocked Sarah especially due to her shy attitude towards sex, equally Julia was surprised that Sarah was so conservative and had never experimented with sex. As I suspected it was Julia who had helped Sarah choose her latest underwear collection and the bikini she wore on holiday in Italy. It was again Julia who had told Sarah she would need to shave her pubic hair in order to be able to wear the bikini and told her that I would love her being hairless permantly. It was as if Julia had made it her personal mission to liberate my wife and she was doing a pretty good job of it. Over the coming weeks Sarah spoke frequently and with much more ease about Julia and her sexual exploits. I openly encouraged the revelations and it became much easier to extract the full details from Sarah, it was evident that Julia went into explicit details when telling Sarah about her latest lover. Sarah told me one night that Julia had the evening before slept with a black guy who was ten years her junior they apparently had sex all night and the guy had a 10 inch cock that filled her like never before her partner Gavin was also present and had sex with Julia immediately after the black guy. It was only a matter of time before I plucked up the courage to ask Sarah whether she had ever fantasised about another man joining us in bed. She of course said not, but my sixth sense was telling me she was lying. I continued the conversation by saying I had, and if and only if she was willing I would be more than happy to experiment. The silence was deafening but eventually Sarah asked me how I could possibly want her to have sex with another man. I carefully explained that when you are in a deep long term relationship like ours no third person could damage that, it would just be a physical sex act for pleasure. It took Sarah quite a while to absorb all this but a little later in the evening she brought the subject up again. I still needed to coax it out of her but she eventually admitted she found the idea very arousing. We had fantastic sex that night and Sarah came twice, that had not happened for a long time! That pretty much brings everything up to date I will now explain what happened last weekend. I’m still pinching myself as sometimes I think it was just a dream but I only have to look at Sarah and she gives me that knowing smile that I’m reliving it all over again as I’m sure she does as well We had arranged to go out to dinner at our local Italian restaurant on Saturday night the children were at their grandparents for the night and our table was booked for eight. We arrived just before eight after having had a couple of drinks in a bar we were intending to get a taxi home so drinking was not a problem. Once we were seated Sarah spotted a guy from her office sat on his own a few tables away from us, she went over to say hi and returned to our table saying his name was Chris and he was waiting for a girlfriend who should have arrived at 7.30 shortly afterwards Chris came over to us to say he was leaving as he had been stood up. Sarah piped up and invited him to join us at our table, I didn’t mind but it blew our romantic meal for two out of the window. We all ordered and consumed several bottles of wine. Chris was a decent enough guy and the evening turned out well. It was about 10.30 when we decided to leave and Sarah invited Chris back to our house for coffee. As soon as we arrived back home the coffee got swapped for wine and we all sat down in our lounge watching the late movie on television. At this point it’s probably appropriate to mention that Sarah was dressed in quite a short skirt with thong low cut blouse and push up bra. We were both sat on the sofa and Chris in the armchair opposite. The way Sarah was sat half draped across me it was not impossible for Chris to see directly up Sarah’s skirt, it was difficult to see without being to obvious but I was sure Chris was looking up her skirt. I tried to rub my hand up her leg with the sole purpose being to raise her skirt a little higher to enable Chris to have a better view. I fully expected Sarah to stop me or push her skirt back down but she did neither. With her thong exposed I then started to slowly slide my finger the length of her slit I could feel the dampness of the material and felt my heart miss a beat. Sarah let out some low moans and Chris saw that I had clocked him watching us. I just smiled at him hoping he would quickly pick up on the idea that something might happen involving him as well. I then had to way up if I should move things on a stage and try to move the material of Sarah’s thong to one side and actually expose her pussy. Sarah had her eyes partly closed and was totally relaxed. Slowly I slid my finger under her thong and ever so slowly moved the material out of the way. My finger touched the lips of her pussy and my heart missed another beat as she was very wet and she was now exposed to Chris’s gaze. Sarah did nothing to stop me and even opened her legs a little more to allow me better access. It was if a magic spell was present in the room and I was conscious that one wrong move could break it. I was now openly fingering Sarah and with my free hand undid her top exposing her bra and boobs. Chris was making no attempt now to hide the fact that he was watching and was even rubbing his erection through his trousers. The next move was critical, sort of make or break as I slowly slid from the sofa onto the floor at Sarah’s feet I made sure I maintained contact with her pussy with my fingers at all times. I continued to slowly finger her and my other hand could just reach her boobs, After a while I slowly started to pull her thong off again no resistance and she even lifted her bottom a little to enable me to remove the thong the skirt followed again Sarah wriggled a little to enable me to remove it. Sarah was now naked from the waist down and my heart was beating like mad, as I was still on the floor it was easy to start licking her smooth pussy she was absolutely soaking, I was aware that Chris had stood up to get a better view of what was going on. I looked up at Sarah and she was pushing her bra down to expose her tits. I motioned to Chris remove his clothes and this he did revealing a nice long hard cock much bigger than mine. Chris moved closer to us and Sarah reached out to hold his cock she slowly wanked him as I continued to lick and finger her. The atmosphere was electric as Chris moved towards Sarah’s head and she readjusted her position a little to take his cock in her mouth. The sight of her sucking another man was the most erotic thing I have ever seen. At this point if I had not stopped licking her pussy I would have come in my pants. I stood up and started to undress myself but never took my eyes of Sarah sucking Chris’s cock. I was now fully naked and tapped Chris on the shoulder and motioned to him to give Sarah’s pussy some attention he didn’t need telling twice and removed his cock from her mouth. Sarah took my cock in her hand and I whispered for her to be careful, as I was so close to cumming. Chris was rubbing his cock up and down her slit and I watched him insert the tip of his cock inside her, he slowly pushed his whole length inside my wife’s pussy until his balls were pressed firmly against her opening. Chris was fully shaved and seeing his bare skin against Sarah’s bare pussy was amazing. They then both fucked slowly building up in speed at which point Sarah had an orgasm. I pushed my cock into her mouth and she barely sucked me before I came heavily in her mouth. Chris groaned loudly and shot his cum inside her. I think this made Sarah cum again as her body shook and she also groaned. I looked at Sarah’s face and saw some of my cum on her lips. Chris withdrew from her pussy and I could see his cum running out of her pussy. As we all recovered the enormity of what we had just done hit me, I half expected Sarah to become embarrassed but it was not the case, she said we should all head upstairs and she only stopped to gulp down her glass of wine before heading upstairs Chris and I followed. When we got to our bedroom Sarah had removed her bra and blouse and was lying on the bed waiting for us to join her. Chris lay on the bed beside her and started to suck her hard nipples. I headed straight for her pussy that was still oozing cum from it. I fingered her to start with but then plucked up the courage to fulfil a secret fantasy and licked her pussy tasting the combined juices of her being fucked by her lover. Chris had positioned himself kneeling on the bed so Sarah could take his cock in her mouth and suck him. It did not take long for Sarah’s mouth to have the desired effect on his cock. Meanwhile I entered her pussy and fucked her slowly, the feeling of my cock sliding in and out of her cum filled pussy was amazing. Sarah was still sucking Chris as I came inside her. I was experiencing a level of horniness that I had never felt before and moved up the bed in the hope that Sarah would suck me hard again. She was concentrating on Chris’s cock in her mouth so I had to get up close before she even noticed I wanted to be sucked. Sarah started to alternate between my cock and Chris’s cock in her mouth; she even rubbed our cocks together across her lips. After a while Chris moved back down the bed and slid his erection back inside Sarah’s pussy. I was unable to come again so took a bit of a back seat watching the two of them enjoy each other’s bodies. Sarah came twice more before Chris came deep inside her. We all drifted off to sleep and when we woke in the morning Chris had gone, leaving a note saying XXX Chris can we do that again sometime !. Needless to say Sarah wanted it to happen again and soon, she admitted that she had never been so turned on and after checking that I was fine with it is in the process of arranging another evening with Chris.
