My wife has, at long last, started an affair with another man, with my blessing. She has fallen naturally in to the role of a mistress, mocking my cock which she says is 'pretty puny compared to his'. This evening she received a text at about 8 o'clock and immediately got up and said she would be back in a couple of hours, before she left she had a quick shower and changed in to a skirt, she grinned at me and said 'how do i look' I said 'Dirty' that was enough for her and off she went. Considering the fact that our sex life to date has been good but fairly 'normal' you can imagine the excitement. After she had gone I sat on the bed and watched television, after about an hour my mobile rang and I saw it was her when I answered all I could hear was muffled voices in the background, this has got to be the most exciting thing we have ever done, there was a lot of rustling and I thought that this was going to be a bit if a let down if I could not hear clearly. I stayed listening in the hope of hearing something, anything that was happening, we had discussed about her leaving her phone on but I though I had no chance at this stage of proceedings given that she’d only just started her affair. Then there was another rustling as the phone appeared to be moved and I could hear perfectly clearly. I heard my wife laughing and giggling like I hadn’t heard in years, she said 'I want you to fuck me, hard with you big cock' and at that point I could only imagine that he rammed in to her because it seemed as though the breath being pushed out of her as she let out a long deep groan. My heart was racing and my head was hot, strangely enough I did not have an erection but my cock was dribbling precum. Almost immediately I could hear a slapping as he obviously banged away at her, then for the first time I heard him, he just said 'wank your pussy for me, go on I want you to come for me'. The noise I then heard on the phone did not sound anything like the wife I , she was so vocal and kept saying come on fuck me come with you massive cock, fuck fuck, she sounded so aggressive, at this point despite not having an erection I came all over myself and remember thinking don’t make any noise. After I had come I could still hear them banging away and he coarsely told her to 'get on all fours' she never said a word but at that point the phone went dead and i just lay there in a state of both shock and excitement. I immediately wanked myself off and came again so quickly I felt like I was 20 again. That was about an hour ago when I received a text saying 'see you 20 minutes’, When my wife got back home, I was in bed waiting for her, she came in the bedroom, beaming brazenly and took all her clothes off and just threw her knickers at me and said 'taste my lover' I held her knickers over my face and they were wet and there was the starchy smell of spunk and her perfume and pussy scents all mixed up. I would have been happy to lay there forever just with her knickers on my face but she climbed on to the bed and said 'quick i need to sit on you face before it all comes out'. As she did just that I was left in no doubt that she had been well and truly fucked, her pussy was hot, wet and had the distinct smell of another mans cock on it, she sat herself well and truly on my face and said 'put your tongue in me' I gladly did as she said and almost instantly a load of thick spunk slipped in to my mouth, this was a first for me and i just lay there for a while before she asked if i could taste her lover, I instinctively swallowed and realised that i had just taken another mans full load down my throat after it had been fucked in to my wife’s cunt. I felt that I was totally and fully being used by my wife for her own pleasure, I felt humiliated, excited, completely the way I have always wished i could be. It was as if my wife had always been aware of my desires, many of them secret, and had given me the ultimate. She turned herself around so as to be able to see my cock and simply said 'wank yourself'. As I wanked she put her full weight on my face and rubbed herself, in seconds she was moaning loudly saying 'wank yourself' and 'god his cock is so good' the tone of her voice got deeper and she started to come. I shot my spunk good and hard making muffled noises as she practically stopped me breathing with her pussy clamped on my face. It just does not get any better than that. All this detail is totally 100% true and I know that she will be doing it again in the near future, she said so. Although I have agreed willingly for her to have other men it is now a case of her doing as she pleases, that in itself is pretty daunting and exciting at the same time. I find it incredibly know that I am being cuckolded. This is a total new experience for me but I know that it will now be the way that my relationship works with my wife and I am completely happy with that.
