The title of this is situation we have now found our self in through friends of friends so I will explain the background before I start. I am Stuart and my wife is Kathy, I am 34 years old and Kathy is 28 and we have been married for seven years. I am of small build and about five feet six tall while Kathy is five feet five inched and a size 12 figure. We have some friends John and Allison who are around the same age as our selves. Then there is another couple Greg and Helen who are John and Allison’s friends but we all meet up about once a month at John and Allison for dinner and and a few drinks. Then one evening we arrived as usual but Greg and Helen did not turn up , John informed us that they have had a disagreement but said nothing further on the matter. It was about ten days later we got a call from Greg and Helen inviting us for a meal, during the course of meal we asked what had happened between John and Allison and all they said it was a delicate matter. We had arrived at around 1.00 o'clock Saturday lunchtime. My twenty-eight year old wife Kathy was wearing a knee length white dress along with high heels and carrying a small leather handbag over her shoulder. She looked good with her radiant smile smile after all she is a lovely woman with a 36 b bust and a round firm bottom which I adore. They invited us out for the evening to a club and upon arrival we found this was no ordinary club and it was a little different to our usual get together s. This was a big deal for both of us really as it was the first time at we had been to this kind of club,, and it was obvious that it was an adult club. They told us that we had been invited to watch a Session' first hand. The two of us where naturally nervous about what was going to happen and and we were worried in case we were to be involved. We sat a a table and ordered drinks before Helen said we will be going upstairs soon. My wife and I are no prudes but we were apprehensive of what was going to take place. They took us to a private room which had a futon no the floor and the lights were dim. My wife and I have watched porn films on the internet and fantasied while making love. We have been equally turned on by the desires of watch their wives getting fucked by other men and enjoyed our fantasies. Once in the room the door opened and we stood in amazement as the Helen stripped off just leaving her g string on. Then the door was opened and a large black man entered the room who later was introduced as Dom who originally was from Zambia. But the shock did not end there as Greg announced that Helen was going to be fucked by him and also bareback. Greg told us that it had begun as a typical cuckold fantasy, watching porn films. He now wanted to watch his wife Helen having sex with well endowed black man. He told how he wanted to see his wife’s pussy stretched wide open taking what he was unable to give her. In turn Helen was longing to take a black cock inside without him wearing a condom. He said that he was also making a video of it, and said it that we could have a copy if we wanted one. Then Dom stepped forward and took Helen into his arms engulfing her white body and the contrast was amazing has he began kissing her full on the lips. As we watched his arms went around her back as they caressed her body before taking her arse cheeks in each hand and pulling Helen tight into his body. They were now kissing each other very passionately almost trying to eat each other. They seamed to be oblivious to our presence and all the time his cock was getting bigger and bigger. When and I saw his cock getting bigger it turned me on big time, and I had images in my mind of of my own wife taking that big black cock. Greg and Helens relationship was probably similar to that of own married life and indulging in fantasies of our wives getting fucked. I had said to my wife when having sex how I would love her to take a big cock as I am not big in the trouser department. This was always a turned her on and she would orgasm and she would shout yes make him fuck me. I also would like it for Kathy, but afterwards she always refused to discuss it in the cold light of day saying it was a fantasy. Anyway getting back to the scene evolving in front of us. We watched as Helen removed her g string and lay down and was being teased with this big black cock dangling at the entrance of her now wet pussy. He then said to Helen tell me what you want, Helen moaned eeeeerrrrrmmm yes. Dom retorted no,,, white bitch, tell me that you want me to fuck you. Helen said come on then fuck me, fuck my married pussy let me feel your cock inside me. Where are your manners lady he asked ? Helen looked at her husband then back at Dom and said sorry, please fuck me. That’s better I like a lady who knows her place so open your cunt for me. So your husband can see my black cock disappear inside your married pussy. Then with great force Dom hammered is cock deep into her and Helens pussy and she was squealing O fuck yes, yes, O fuck, fuck. His pace got faster then slower as Helen arms were around Doms back as she moaned oooooooorrrrrrr Dom fuck me Dom. Helen started to orgasm and at the same time Dom clenched his buttocks and asked where she wanted his sperm and cried out inside me,, inside me. He shouted take it bitch take it all and he proceeded to empty his sperm inside her. Helen was screaming give it to me, give fill me up ,, I want your juice. Dom then slowed to a stop , his cock buried up to the hilt in her pussy then as his cock began to soften he pulled out and there was loads of thick creamy white semen flowing from her stretched hole. Dom turned round to face Greg and said that’s it,, your bitch will be pregnant and in nine months time there will be a black baby coming out of her white married belly. We stood in amazement as we have never before witnessed anything like this in real life. Dom then left and Helen got dressed and we had a drink downstairs before we returned to their place where we spent the night. But before retiring for the night we talked about what had taken place and were we offended by it. We told them we were not offended but it might have been better if they had told beforehand. We discussed would we still remain friends absolutely why wouldn’t we. They then told us that they had told John and Allison beforehand what they were thinking of doing and this is why they no longer speak to them. While in bed that knight Kathy kept talking about the size of Doms cock and the contrast of his black cock in her white pussy. It had certainly got Kathy all hot and bothered as she was wanking my cock and whispering in my ear to fuck her, and to fuck her hard. I did my best but did not want to make a lot of noise as Greg and Helen were in the next room. It was hard to keep Kathy quite the nights activity had made her really hot and she was all over me like a rash and she pulled me onto her and she was begging to be fucked. I had to keep my hand over her mouth to stop her moaning out loud and I did fill full of my sperm. But she was awake for about two hours trying to get me to fuck again but enough was enough for one night. We left the next day at lunch time with a copy of the video and all the way home Kathy kept going on about how Helen had the that black man fuck her bareback. Upon getting home we were no sooner through the door and Kathy jumped me not that I was complaining but she wanted fucking really hard . Now I am not well endowed and I am not a match for what she had witnessed the night before. Over the next couple of weeks we watched the video every night and the she would want fucking more than once. Kathy was always on the phone to Helen but not always in the same room as myself. What they were talking about was probably Helens night with Dom and that she might be pregnant by him. Not that I can be certain of that because Kathy just said they were talking about life in general. But since that night this has had an affect on Kathy as she has been permanently horny and she has been wearing me out. Things however did not end there so I will finish this at a later date as she is calling me from upstairs.
