My wife had an affair, which I discovered, but I encouraged her to continue with it. She told him I now knew about the two of them. After this she said he was less confident in bed with her, as he was worried that I would be jealous and angry, and one day confront him. So wife and I discussed how to boost his confidence. I suggested that she should tell him that he was better than me in bed, or that he had a bigger cock, or whatever else she thought might work. Anyway, over the next few weeks, maybe months she did exactly this. When I asked her some time later if he was more relaxed about continuing to fuck her, she said that he had slowly got better and better, and was now quite the stud! I asked her what she had said to him, and initially she was reluctant to say, and eventually apologised, as she said she had probably over done things. She slowly, and with much coaxing on my part, admitted to telling him that when we first met that I came inside my pants several times on our first 'heavy' dates, and that I used to cum as soon as she touched my cock. She told him that I had improved a lot since then, and that I could normally last for 5 to 10 minutes these days, but that I still sometimes came too quickly if I had gone a while without sex. I was a bit taken aback by this 'confession', especially as it was totally untrue! But it did get me excited too, which my wife noticed, and made fun of. I told her I forgave her, and that she could continue to tell him stories of how he was the better lover. It seems the more she 'belittled' me the better he performed! She 'confessed' to him, over the following months, that I had a much smaller cock than him (mines not much smaller in reality!), that I had never made her orgasm (true!), and that I was a frequent masturbator, (true-ish: Define frequent?) wheras he claimed he never did. She also told him that she would regularly sit on my face when she came home from his place, and make me lick her clean (true!), something he found difficult to believe. But he often fucked her a final time in her visit, just before she left, which he told her he really enjoyed doing. We all got together much later, and, under questioning from both of them, I slowly 'confessed' all my 'inadequacies'. God, those conversations were some of the horniest memories I've got! The worst/best confession I had to make was about never having made her orgasm with my cock. It was something she thought I ought to do, especially as it was true, to prove to him he was better in bed. I was reluctant, but she threatened some lengthy denial if I didn't. So, one evening, after they had finished fucking upstairs, the three of us were sat around drinking, all naked, me still with an erection, her open legged with an obviously wet pussy. She said to her boyfriend "why don't you ask him about his sexual performance?" She said that he could ask as many questions as he wanted, and she assured him that I would be truthful, under threat of long term withdrawal of my sexual privileges. He asked a number of questions, and then she leant over and whispered something to him. He then asked me if I always managed to give my wife an orgasm every time I fucked her? I immediately knew where this was going. I had to confess that, no, I didn't manage to make her come every time. My wife then told me that her boyfriend made her come every time, sometimes twice, and had done from the very first time. He then asked if I'd estimate my success rate at about 9 out of 10 or lower? Me: "lower". 8 times out of 10 or lower? Me: "lower", and so on, with him sounding more incredulous as my 'success' rate was proving to be lower and lower. When we got down to 1 time out of 10 or lower, my wife jumped in and said "Why don't you just tell him the actual total number of times you've made me orgasm, in all of the many years you've been fucking me?" My heart was pounding so fast. After a long pause I just said "Zero. I've never made her come in 12 years of fucking her". He got a real big grin on his face, and my wife said "See, that wasn't so difficult to admit to in the end, was it?" It was. I didn't cum while I confessed, but I was leaking like never before, and didn't dare touch my cock for some time. I doubt whether I would have cum just by touching myself at the point I was describing above. Something I've never been able to do. I actually always need quite a bit of physical stimulation to finish. Although, I must admit, if I had of just started voluntarily spurting at that moment, that would have been even more humiliating! I would just like to add, for clarity, that I am not a wimp, or sissy. No disrespect to those who identify as such. I probably fall into the category of alpha male, although I don't particularly agree with the alpha and beta concept. My wifes boyfriend in real life has less of a dominant personality than me. He is several years younger than me, and worked as an assistant manager in the same place of work where my wife was the branch manager. I was also a branch manager, in another location. Being sexually humiliated by someone 'junior' to me makes for the most intense sexual feelings I've ever experienced, often leaving me phsically trembling/shaking, with a very high heart rate. In our sexual relationship her boyfriend started out very uncertain of his position, but over time came to enjoy being the dominant one. I like to think I trained him well. See, the alpha surfacing in me! We do, all three, socialise a bit outside of sex, and then I re-take my place as the more dominant one. But at all times we have great respect for each other.
