I'm Dave and My wife Alison, aged 52 and is generally shy and quiet. I she's pretty and keep herself in shape. She's a brunette with a Bob style hair cut, at 5'2" size 12. Her breasts are average for her size, but her nipples are big and very sensitive; so much that she can sometimes reach orgasm when I suck and caressed them in the right way. We have a great sex life and have always had sex several times a week and been quite adventurous, although until recently this hasn’t included participation with others. We have been watched having sex and I like Alison to flash, so although she's quite shy a few guys out there have had a glimpse or two of her breasts and shaved pussy (mainly lorry drivers). Basically Alison does what I like as we have a very high sex drive and my favorite thing is knowing other guys want her and are turned on by her. Fairly recently I have asked Alison if she had the chance would she go with a well endowed guy. I thought she may think this was a step too far but after she realised I was serious she found she couldn’t get the thought of doing it out of her mind. A few days later Alison told me she had pleasured herself a couple of times and imagined one of my mates having her. The One we nickname horse, for obvious reasons, and is really good looking, and she sadly wrongly thought that this was who I had in mind. I kept going on about it, especially when Alison said she would consider it, and after me asking her again she eventually said she would do it. As long as I would make the arrangements and if it went wrong then she would not be to blame. A couple of days passed and I broke the news that we would be getting a visitor that Saturday. She couldn’t believe it was really happening. All I told her was that a guy would come and give her a massage and see how things developed. Saturday arrived. I love Alison's shaved pussy, and I asked her to wear white matching lacy g-string and bra with a dressing gown over. I forgot to say that I have an average cock size wise and have always said that Alison deserves to try bigger. She always says she loves my cock and it is perfect for her. The thought of her having bigger excited her but also scared me. The door knocked and Alison was shocked (and initially disappointed) that it wasn’t horse that I let in. Instead I was introduced to Kev who she later found out was 62! Kev is a charmer though and a really nice guy. He is also good looking and had a great body, especially for his age. I then took control and offered him a drink and I got them both beers and after handing them over I suggested to Alison that she should take her dressing gown off. She was standing in the middle of the lounge and very nervous and shy but did as she was asked, stripping for this older stranger in our own house. Very soon Alison was standing there with Kev checking her out. her bra and string left little to the imagination and her nipples, and shaved pussy were on clear display through the sheer material. I asked Alison to turn around so Kev could also check out her bum. We hadn’t discussed exactly what would happen and she expected a massage but that didn’t happen and I was soon telling Alison to sit on Kev’s lap. Kev complimented her and soon had his arm round her. I then told Kev that he was free to do what he liked with Alison, Alison glared at me but didn’t object. Kev was soon stroking her arm and then her legs and up her inner thigh. She started to relax as she was getting aroused by Kev's touch. I then told Kev that Alison had great tits and asked her to take her bra off to show him, She did soon Kev was touching them which he said felt good. Kev lent in to kiss Alison and she responded and soon his tongue was probing her mouth and she started to forget that I was there. That didn’t last long as she told me she wanted to take Kev to our marital bed. Still in just her g-string she got up and led Kev into our bedroom and I followed and sat in a chair in the corner. they kissed again by the bed and Kev's hand was groping her breasts and bum. She then helped Kev take his top off and then his jeans. I could see a very large bulge in his pants and knew this guy was big. Alison looked over at Me, now silent and I nodded for her to go on. I knew she was happy as he was stroking his cock through his underwear. That was her green light to go so she dropped to her knees and like a kid opening a present she peeled down Kev’s pants. He was huge and she knew then why I had chosen him. His cock wasn’t massively long, although still three inches longer than mine. It was the thickness of his cock that made it massive. Alison's shyness had gone and the slut in her took over and taking his huge cock in hand she took what she could in her mouth and sucked like a little slut. Kev clearly loved it and so did she as her mouth started to take Kev's monstrosity. Her body was desperate to be pleasured so after a while she got up and laid back on the bed. Kev lent forward and gently took each side of her g-string and being a gent said “may I?” Alison nodded and soon Kev was peeling them down exposing her pussy. It looked like a few nerves came back, but these were due to the size of his cock and knowing where he would want to put it. But he was gentle and kissed her passionately before lifting her up and putting a pillow under her bum. He kissed her again and slowly worked down her body spending a lot of time on her nipples. She was moaning now I & Kev knew she was loving it. She wasn’t far from orgasm when Kev moved down her body. I didn’t complain as he was heading between her legs. He was a tease and kissed all round her pussy but had her legs parted wide with the pillow lifting her up, which was fully displaying her married shaved pussy to him. He lay between her legs and then gave her pussy the longest and best licking it had ever had. Due to his teasing and expertise Alison had her first orgasm soon after his tongue first found her clit. Soon his finger was also in her and caressing her g-spot sending her into multiple orgasms which is rare for her. He also licked her bum hole probing his tongue into her. She never let me do this, as a loving husband, but really enjoyed her new lover doing it. Then Kev also slid a finger up her bum, which took her by surprise but she just enjoyed this new experience. Her pussy was so very wet and she wanted his monster cock, and She shocked me as she demanded Kev to fuck her. Soon Kev was positioned with his massive cock at her tiny shaved pussy hole. He was gentle and she was very wet so it went in far easier than I imagined, Alison said it felt huge in her, especially as he started to fuck her. I suddenly realised that he didn’t have a condom on but didn’t really care. Alison didn’t want to look at Me, I hadnt said a word for ages. I just stared in awe at this older man’s performance in front of me as he pumped by far the biggest cock I have ever had inside of my wife. Alison was in heaven and her pussy crammed full of cock and didn’t want the feeling to end. Another orgasm approach and she realised she was moaning probably louder than ever she had with Me. She is flexible and loves having her legs up in the air straight in a V shape while being fucked, with Kev holding her ankles she couldn’t hold this position for long with Kev fucking her. I decided to get naked and join them on the bed holding her legs in this position for Kev, clearing loving watching my wife being pleasured by a much bigger cock. I then tried to feed my cock in Alison's mouth and she tried to suck me the best she could but found it hard as Kev was pounding in her. This was amazing. I had started to get a bit concerned that We had gone too far for Alison but clearly not, she was I fully relaxed and enjoyed the fuck of her life. Kev was still going but I surprised Alison and shot my cum into her mouth and over her face. Kev slowed as this happened and Alison swallowed what was in her mouth and grabbed a tissue and wiped her face. Thinking Alison may have had enough Kev pulled out of her but she wanted more. She loves being on top and told him to lay on his back, and soon she was lowering her wet and stretched pussy back onto him. I sheepishly sat back down as she started to ride Kev's huge cock again. Forgetting she had just had my cum in her mouth she bent forward and kissed Kev, who didn’t seem to care. As she rode him, he groped her bum with both hands thrusting her up and down on his cock. He then put a finger back up her bum and that sent her over the edge again to yet another orgasm. she was bucking and squealing like a complete slut. she seemed to love his finger up her bum and saw me hard again wanking. I have always wanted to do her up the bum and for the first time ever I think she wanted this as well, so I called to her for me to do and she replied yes. I didn’t need asking twice and grabbed some lubricant, rubbed it on my cock and positioned myself behind her as she lent forward onto Kev I slowly slipped it in her bum. She really was in heaven with both holes filled. Rhythm was awkward but it was fun, but soon she said her bum hurt so I pull out. Somehow Kev hadn’t cum but he asked to do Alison doggie style. Soon he was pumping her harder than ever as she knelt over the edge of the bed and he stood behind her fucking her, holding her hips. He went faster and faster and I could tell he was approaching orgasm. Alison must now be sore by this time but the pleasure was still greater than the pain. Then he pumped his cum In her. she said it feels like there were pints filling her up and we soon lay exhausted on the bed. she was totally satisfied laying on her back with legs wide and her new big cocked lover’s cum dribbling out of her stretched and used shaved married hole. Alison told us she couldn’t take any more and Kev was soon on his way only after Alison had made me promise to let him visit her again at anytime. After Kev left I went back in and she hadn’t moved. I asked if I could take some pictures of her with her pussy full of Kev's cum. I was hard and wanted to fuck her but she was too sore. Jokingly she said she would suck me off if I licked her out first. Alison is rarely shocked by Me, but was, on this occasion as I lent forward and licked Kev's cum out of her, Although it freaked me out a bit, I found it really horny, and for maybe the first time she was the one in sexual control. Of course she returned the favor and sucked me off again. Meeting Kev has took our marriage to a new level. We spoke after and we opened up even more to each other, We have also joined another couple and Alison has had her first taste of another woman’s pussy. We met Kev twice after this and had great sex, I’m happy to share some of these other experiences if you liked this one. Dave & Alison xxx
