We have been married for 9 years and together for over 12 – our sex life used to be very good but over the last 2 or 3 years it had gone steadily down hill until one random event conspired to change the whole basis of our relationship and my wife's attitude to sex. We have always been very close and really rather private – our lives revolved almost exclusively around each other – no wonder we lost the spark. I think we have both been faithful these last 12 years. In the autumn we went on holiday with two other couples – I guess you could call them friends but they were not people we were particularly close to. It was a largely uneventful holiday until one afternoon we all drank just a little too much (in the hot sun) and by 10:00pm we were all wrecked and ready for bed. Just at the moment where I thought someone would utter the words – “I’m turning in’ one of the guys stood up removed his T shirt, dropped his trunks and jumped in the pool stark naked. Everyone stood up laughing nervously and I remember my wife saying to me “what should I do” – I thought it was a really dumb question and I didn’t even offer a reply – I just stripped and jumped in along with the others. I noticed ‘L’ (my wife) standing on the side stripping naked in the half light and getting a glimpse of her breasts and her pubic triangle before she walked into the pool down the steps. Picture the scene 3 men and three women all pissed and stark naked and thrashing around in the water, all was good until one of the guys ‘A’ got out of the water sporting an erection – a huge one that made quite an impression (even) on me. I was hugely impressed by the sheer size of it and noted the massive head protruding out from the foreskin that was pulled right back - straining. Later that night ‘L’ and I made love – for the first time on the holiday – she was ultra turned on and it was outstandingly good - I couldn't recall her pussy being that wet for years. In the post sex conversation ‘L’ said did you see “A’ had a ‘hard on’ earlier – I acknowledged that I’d seen it but how could you miss it was more the point. ‘L’ talked about that erection and the size of ‘A’ penis almost none stop, I was sure she thought about it when we made love and she later confessed that she had started to think about ‘huge cocks’ when she masturbated. Over the next few months our sex life improved dramatically but I was left to feel more and more inadequate – my cock (6 inches) is pretty average but I couldn’t compete with the memories of the huge cock we saw on holiday or the huge dildo that had recently arrived in my wife’s bedside cabinet – which I wasn’t sure I was supposed to know about. She was clearly ramming this huge pink cock into her pussy when she masturbated and fantasised about some big stud fucking her. Just a few weeks ago we woke in the early hours and found ourselves making love – in the depths of passion I gently quizzed ‘L” about that night on holiday when she saw the ‘big cock’, what did she think, how did she feel etc… ‘L’ was really open and honest about everything she told me when she saw it she just wanted to touch it – “get my hands around it and wank it’, she imagined he's cum really heavily given the size of it, she said since that night her pussy had longed for a massive cock, she “wanted to be overwhelmed by a big fat cock that was too big for her little pussy”. She did try to re assure me about our relationship and my average cock but I knew she had developed a fascination for big cocks and it wasn’t going away. She admitted that when we made love on holiday she was so excited thinking about ‘A’s cock – she spent the final few days of the holiday ‘wanting him’ knowing it couldn’t happen. She confessed to masturbating uncontrollably when alone like a schoolgirl searching for a “higher level of satisfaction” plunging more and more fingers inside herself. It was all very odd we were having lots of sex, we were being very honest with each other – my wife had never admitted to masturbating when alone before - but deep down our relationship was seriously broken and I was starting to get very worried. Over the next few days it became obvious that ‘L’ had to have sex with a “big cock’ and she wouldn’t rest until she had. I was uncomfortable with the thought of another man screwing my wife but I simply couldn’t give her what she craved. We were also unsure how we found a man with a big cock – plenty claim to be ‘huge’ but few actually are. We did discuss but quickly rejected the notion of asking 'A'. Eventually, we pulled an ad together for this site and she stipulated that she was looking for a meet for no strings attached sex with a man with a big cock – at least 8 inches – she also asked for someone under 45. Not unexpectedly she got an awful lot of replies (within a few hours). Many more than we expected but lots of them looked like timewasters, some were miles away and some a bit unbelievable. We quickly narrowed them down to six. In the six was a young Asian guy who sounded genuine and who claimed to have a massive nine-inch cock – he promised pictures and he was relatively local. Eventually my wife started email correspondence with him and photo’s were exchanged he was young, good looking and his cock was massive before it was erect in the photo’s. I was also reassured that my wife was unlikely to run off with this guy - apart from the cock he was so not her type. A meet was arranged – he was coming to ours – but ‘L’ insisted that I wasn’t to be here and she kept changing her mind in the days leading up to the meet as to whether she was gonna go through with it or not. The meet was set for yesterday – I was booted out and spent the afternoon – out thinking of my wife and wondering whether she was really cheating on me. I assumed the worst. I stayed out for what seemed like forever, before going home just after 7:00 pm. I knocked on the side door unsure whether to go in – my wife let me in and she was cleaning up in the kitchen wearing jeans and a T Shirt like nothing had gone on or happened. After a couple of minutes of niceties and avoiding the conversation I ked – “have you had your big cock”. Her eyes welled up and she started to cry and she said she was so sorry. We cuddled and kissed for a while and she told me how her man had come round and how they had made ‘mad passionate’ love in our bed, she said he was huge, she'd loved sucking and wanking it before he's eased the huge thing into her soaking pussy and she said he felt amazing inside her - so big and tight - but she questioned what it was doing to our relationship. I asked if he came inside her. She said yes but he wore a condom – as she’d insisted. I stripped her naked and fucked her for all I was worth on the living room carpet – smelling another man on my women. I licked her pussy knowing another guy had licked and fucked it earlier - it really turned me on but I felt so scared. I have not had all the intricate details yet but I will get them over the next week – things are at a delicate stage – our relationship is up in the air ‘L’ seems to want to save it but this ‘being satisfied’ by a big cock won’t be a ‘one off’ and her desires are not going to go away. I either accept her for the way she is and let her do this or simply move on. I suspect it will be the former but who knows my emotions are all over the place right now. Writing this has helped.
