I have been married to Lisa for Ten years, our sex life was always just ok and very conventional she had come from a very conservative family who had victorian values. They thought sex was only for producing children and not to be enjoyed !! dont get me wrong we fucked on a regular basis but try and suggest different positions or anything a bit more adventurous and it was a big no no. Add two children and an increase in her weight and sex was only on special occasions and if possible in a darkened room. I sought my pleasures elsewhere and although she suspected I think she thought it was the esiest option. Roll forward to 2001 and Lisa started to get friendly with a work friend who was also overweight and they both toddled of to weight watchers. I thought it was a bit of a fad but they both continued to lose the pounds that soon turned into stones. I could never find anything appetising to eat in the house but there was always the takeway down the road for me. During the summer of 2002 Lisa proudly announced that she had returned to her pre marriage size ten and I started to notice a change in her personality her baggy clothes had gone to the charity shop and been replaced with figure hugging clothes that showed off her trim body. Visits to the hairdressers were more frequent and she had the makings of a sexy women again. I know it sounds daft but the physical change had been over such a long period that i had not really noticed until she started to wear designer underwear. The M&S smalls were in the bin and she was wearing thongs along with matching bras. One evening when she was undressing for bed Lisa casually mentioned that her thongs were so skimpy that her pubic hairs poked out the sides and looked unsightly. Never being one to miss an opportunity I said why dont you trim your bikini line. I expected a retort of of dont be so purvey or similar but she thought it was a good idea and asked me if I would do it for her.Not quite believing what I had heard I was in the bathroom collecting the equipment before she could change her mind.The first trim was very mild and she was insistent that that I only shave the minimum and although she me allowed to shave close to her pussy I could not convince her to let me shave her pussy lips. Even with the limited shave it turned me on a great deal, and I could not hide my modest hard on. Lisa was bemused that the exercise had turned me on and that night we had a very erotic fuck. Still pretty conventionla by this boards standards but for us it was a leap forwards.The frequency of our fucking improvd over the next few months and the shaving continued about once a fortnight. We had occasional hiccups with shaving rash and itchy regrowth but Lisa continued to let me shave her. Each time I would shave just a little bit more hair off until eventually her cunt lips were smooth and she had a strip of pubic hair about two inches wide on her mound and even this is trimmed short. The whole look drives me crazy and she has commented that I pay her more attention now than when we first met. Lisa still finds it amusing that I get turned on so much by her shaved look but admits that she prefers it on helth and cleanliness grouds if nothing else. Our sex life continued to flourish and her Christmas stocking that year contained things like fishnet stockings, peephole bran and crotchless knickers. although she would only wear these items in bed as a bit of fun it was something i would have never considered buying her jus the previous year. Gradually she felt more and more comfortable talking about sex and I started to hint at what her sex fantasies might be. She claimed not to have any but it prompted her to ask what mine were.I started with the mild stuff and eventually plucked up the courage to mention threesomes. This shocked her a little but she wanted to know more. I confessed that having another girl join us in bed would be my ultimate fantasy. Lisa said it wasnt for her and did i get of on thinking of her touching another girl. I of course told her i did and that its was most males ultimate fantasy. After several occasions discussing the same theme she asked what else I fantasised about. I told her i would love to see her with another man. Lisa said that alas it would also have to remain just a fantasy. We both agreed that fantasies were fine but that was as far as it went. Sorry this has been so long but it was importaint to cover the background in order to fully appreciate the next bit. A couple of weeks ago i had a phone call from an old mate of mine that i used to work with and had not seen for three years. He was intending to be staying near us on business wanted to visit one evening.I was pleased to hear from him and suggested he stay with us rahter than use a local hotel.Lisa had met him a few times when we worked together at company social events and got on well with him. When Dean arrived we got on like we had in the old days and agreed that we shouls get together more often. The evening went well the kids were shipped of to my parents for the night and we went out to a local restaurant we came home about 10.30 and had already consumed several bottles of wine. Lisa opened another and we were all quite merry by the time we went to bed around midnight.As soon as Dean had gone of to the guest room we cuddled up in our own bed. Lisa was quite giggly and said she was surprised I hadn't been suggestive as there was a spare man in the house just down the hallway. I replied that the thought had crossed my mind but figured it wouldn't go down very well. My heart skipped a beat as i said shall I go and see if Den's up for some fun. Lisa said you woulden't dare you are all tak aren't you. The banter continued until I got out of bed and said unless you stop me before I get to the door I will go and get him. As my hand turned the doorknob I took aglance at Lisa she just winked at me.My heart was in my throat and if it had not been for the drink I would have bottled it. Deans light was still on and I knocked on the door and went in, he was surprised to seem me stood there in my boxers and asked if everything was ok. I sat on the edge of his bed and blurted it out "Lisa want to know if you would like to join us in bed for some horny fun" Dean looked shocked for what seemed like ages and just nodded and smiled. He got out of bed naked and followed me back to our room. Lisa had moved over to the middle of the bed and Dean slipped in beside her I removed my boxers and got in the other side, my stomach was doing somersaults and my cock was as hard as steel.There were a couple of seconds of awkward silence before Dean made the firs move and Kissed Lisa, the short kisses soon turned into a lenghty snog and she seemd to relax very quickly. I pushed the duvet down the bed a little revealing Lisa's tits her nipples were hard and as they were still kissing I started to lick and kiss her boobs. I was then conscience of Dean's hand on her other tit caressing her flesh, his hand was soon replaced by his mouth sucking on her nipple. The atmosphere was electric, i moved slightly away to allow Dean more space. I kicked the duved further down the bed and we were all in full view of eachother. Deans cock was up like a flagpole, about seven inches long and thicker thsn my own. I saw his hand move down Lisa's body and without hesitation she opened her legs to allow him access. I watched transfixed as he slowly inserted a finger into her cunt, she was very wet and let out a sigh of pleasure as he fingered her shaved pussy.Lisa's hand had moved onto his cock and she was slowly wanking him. This continued for a while and I just enjoyed the sight before me and wanked my own cock.Lisa who was still kissing Dean pulled away and said in a low voice please fuck me. It was at this point it took all my self control to stop myself cumming. Dean moved in between Lisa's legs and I watched as I saw another mans cock enter my wife's pussy. He entered her slowly but with ease as the whole of his cock pushed inside her. They soon got into a slow but hard rhythm and the emotions I felt were just incredible. Lisa locked her legs behing his back and moved with his thrusts as he fucked her. There fucking became very intense and Lis came powerfully just as i saw Dean's arse clenching as he pumped her full of his own come. They kissed for ages before coming down slowly from their fuck. Dean moved back up the bed alongside Lisa. I desperate to come moved between her legs to replace Den's cock with my own. I looked down at her swollen cunt and saw his come leaking from her. I entered her and the feeling was so intense i lasted no kore than a couple of minutes befor adding my own spunk deep in her pussy. We all rested for a while and then i saw Lisa's hand playing with Dean's cock again she soon had him semi hard and he moved into a position where his cock was level with her mouth. She did not hesitate in sucking him, after a while I got into a similar position the otherside and with one hand on each cock she sucked us both back to full hardness, several times she rubbed our cocks together whilst she took breath I found this incredibly erotic and I guess Dean did as well. this continued for a while until Dean said he wanted her again Lisa without being asked got on all fours and Dean entered her again from behind she continued to suck on my cock. Their fucking this time lasted much longer until eventually we all came, me in her mouth and Dean for the second time in her cunt.We were all shattered by now and it was 3 in the morning. Dean returned to his room and I had to change the bed sheets as they were soaked. The next morning Dean had left early and Lisa and I cuddled in bed the atmosphere was tense until eventually Lisa sobbed she could not believe what she had done and blamed the drink. I assured her that we should have no regrets and It had been a most erotic experience. for the next few weeks things were alittle awkward between us and even I wondered if it had been a mistake. I will post an update soon as there is more to tell.
