My name is Rodney and I've been married to my wife Dot for nearly thirty years . She's 50 now, five years younger than me, but still gorgeous with short platinum blonde hair and a curvy 38 dd figure and could easily pass for someone a decade younger. In the last year or two our sex life has diminished a little, but I assumed this was only natural as we got older and when we did make love  to me it was always good. One evening we were at home together just the two of us, our three sons are grown up and have long ago left home, when just after nine o'clock there was a loud knock on the door. Dot was upstairs , so I answered the door and a tall well built young black guy  was there. I asked him politely what I could do to help  and he told me that he was here to fuck my slut wife who was his bitch. I told him to leave or I would call the police  but he shouted for Dot to come down as he was going to give her a good fucking. To my surprise Dot sashayed down the stairs wearing a sheer  silk nightdress I'd never seen before, dropped  to her knees said "I want your beautiful black cock !" unzipped the young man and proceeded to suck hungrily on the biggest dick I'd ever seen. I was horrified but Dot said "Watch and learn how to treat a woman from a real man." She then slipped off her robe and I was astonished to see that not only had she had her cunt shaved and her navel pierced with a belly chain attached, but she sported several tattoos including  a daisy chain round her hips and a black cock and balls on her breast. Her lover then took out of his pocket a set of  nipple clamps which he attached then proceeded to pull violently until my wife groaned, while with his other hand he fisted her cunt violently. She came almost straight away, and as she lay on the floor writhing while I was still frozen with shock on the armchair , he kicked off his jeans which were round his ankles, walked arrogantly into our kitchen  and emerged smirking with a bottle of olive oil. He proceeded to lubricate, massage and anoint my wanton wife , pulling her clamped nipples until they got  ever more swollen, then proceeded to fist my sexy wife's arsehole with his huge hand. Having lubed his cock by pouring oil on it he drove the monster  up my wife's arsehole in one swift motion before buggering her violently for the next hour. When he had finished and come inside her  he pulled out with a  plopping noise and to my disgust Dot began to suck hungrily on the cock that had just been plowing her arse and was now slightly stained with her shit, as if it were a chocolate lollipop. They then  walked upstairs together with Dot telling me that they were going to have a shower together and fuck some more. Half an hour later, having wanked myself to a climax twice , I ventured upstairs and through the open bathroom door could see Dot, on her knees in the bath, her face and hair covered in a prodigious amount of spunk which her fucker proceed to clean off by hosing her down with a torrent of piss before she opened her mouth and swallowed what looked like gallons off the stuff. At this point I began to weep tears of self pity  but Dot told me to fuck off downstairs and open a bottle of wine as they had something to show me. Five minutes later they came downstairs, both still naked but now dry and Dot's lover, who introduced himself as Mikey put a Dvd in the player and told me to sit back and enjoy. For the next hour I proceeded to watch my lovely wife gangbanged by a group of 10 young studs, the majority of whom were black, while her best friend Norma  acted  enthusiastically as a fluffer. As the screen action unfolded and I saw my wife used and abused by a group of well hung young men who fucked her two or even three at a time Mikey slid inside Dot and began to fuck her  well stretched arsehole again. The film ended with the 10 young men emptying the contents of their cocks and balls all  over Dot and Norma's faces and tits and the two insatiable bitches then  began to swap the spunk  from mouth to mouth while their erstwhile fuckers pissed on them. After the film finished, Mikey informed me that unfortunately they had not managed to impregnate Dot at the gangbang, but they had another one planned soon and would continue to gang fuck her and make porno films of the events, which they posted on the internet ,until they'd bred her with a black baby. When I then asked Dot why she had done this to me she informed me that I had always been a selfish bastard in bed and that she and Norma had been having a lesbian affair for years,  until Mikey and a friend picked them up in a pub, took them home and introduced them to the joys of black cock to which they were now both addicted. Since that night I've seen lots of porn videos of my beautiful wife ,taken at public toilets and dogging sites among other places, once a month she goes over to Germany where she features in piss drinking porn films  and two days ago she came home and announced proudly that she was pregnant , that she had no idea who the father was, but she knew the baby would be black because she'd only allowed the white men who fuck her to come up her bum and in her mouth. I am now a full time cuckold and I've never been happier, Dot doesn't allow me to fuck her these days but I'm allowed to lack her fuckers spunk from her cunt and arsehole when she comes home from one of her gangbangs or dogging sessions.
