We lived together first for nine months before we got married. In those nine months we regulary watched porn together and lots of the ones we chose together, were ones showing men watching their wives being fucked by black men with big fat cocks. After our marriage things sort of settled down for a while until my wife found a web site for men who liked their wives being fucked by black men. Once again we started to watch this type of porn before, during, and sometimes after we'd had sex, with my wife always getting very turned on. One night she implied as I was fucking her ass, it would be nice to have a big black cock up her pussy right there and then. I got very excited by the thought and agreed with her. Not much later after I'd cum up her ass she asked me if I'd consider letting another man, a black man, fuck her. Still horny and just having unloaded deep up her ass, I said yes. It was around her birthday a couple of months later she asked again, this time she put on a show for me with a black dildo I didn't even know she owned, fucking herself with it as I masturbated. Once again she asked me if I or she could invite a black guy to come to our house and fuck her. This time I said definately, she said "Good, we'll look online for a guy to join us". Craigslist has many adverts for different kinds of sexual contacts and that's how we were contacted by Malcolm, after I'd put an advert asking for clean, well endowed black men to fuck my wife. He seemed like the perfect choice, both for my wife and for me, as he had everything my wife wanted, muscles and a big thick black cock, as well as after lots of correspondance with the both of us, he insisted on me being there to watch and join in. Fantasising about your wife being fucked by another man and actually doing it are very very different things, as I found out a week later. Malcolm arrived just before eight at night and by the time he left at two in the morning, not only had my wife taken his huge cock in her mouth, pussy and ass, he'd also made her into a black cock hungry slut. She couldn't seem to get enough of his large black dick and when I went to fuck her she didn't really want to know. I ended up watching from the floor of our lounge masturbating as he fucked her over and over again, with my wife begging him for more. We eventually split up after Malcolm pretty much moved in, and she became derisory over the size of my cock and my sexual staying power. I only watched them twice more after the first time, both times my wife had me sit away from them as she taunted me, and both times Malcolm came deep up her cunt. It was the wrong choice in every conceivable way for me to let another man fuck my wife. Now I live on my own, sometimes with sight of them together walking down the road we used to live together on, with a child I should have been the father of.
