We were all hanging after a party at a friend's house. My wife and I were the only couple left other than our friends who owned the house. The atmosphere was low key. Everyone was dressed smartly but casually. The conversation was about the problems this one couple was having with their sexuality. I was kind of surprised by the conversation and a little turned on. Before I really realized what was going on, the conversation meandered to a discussion of how we should all relax more. Then all of a sudden while we were sitting around in their living room when our host, a handsome black man and his wife begin kissing and she undoes his pants and begins playing with his cock. It was long, large, rock hard and pretty impressive. His ife then began sucking him. I couldn't believe it. I mean I'm not used to this kind of openness and sexual display. I was in shock. I looked over at my wife and was surprised to see her smiling and looking happy. The next thing I realize is that this guy pulls his cock out of his wife's mouth and starts walking around. To my utter amazement my wife grabs his cock and sucks on it once as if trying it out. I was flabbergasted, amazed, and in shock. I found myself somewhat aroused, but emotionally confused. She had totally surprised me. She seemed to enjoy sucking another man's cock and was more relaxed than I had ever seen her. Not only that, but his wife then sits beside me and we start making out. While we kissed and touch each ther, my wife continued sucking that big black dick. She took it deep inside her throat swallowing the whole shaft and taking her glistening tongue and running up and down his smooth shaft. I had gotten up from my seat and was starting to say something when he quickly blew his whole load and she swallowed it all smiling and looking besides herself. She looked so happy and satisfied and I found myself strangely turned on and disturbed by the whole thing. To my total amazement was my wife lifted her skirt and laid back on the carpet. Before I could say anything our host had pushed her panties to the side and rammed his huge black cock inside her, her juices squirting everywhere as she let his giant cock slip into her easily. She moaned intensely and smiled gleefully. I couldn't believe what was happening. My mouth was agape as he pounded his hard cock deep inside her putting her legs over his shoulders. She screamed a deep intense moan and yelled "yes yes yes fuck me harder you're so fucking good." His wife, who was sucking my cock by now, smiled and asked me how I liked watching my wife being taken by a huge black cock. I admitted that it excited me. She laughed and pulled at my hard cock. "I can see that," she teased. She said she was going to take care of me and soon was straddling me and riding my cock. Although she seemed to enjoy it, I could help but wonder how she really felt since her husband's cock was twice the size of mine. Later I asked my wife how she liked that big black cock. She said it was an amazing experience and asked if I objected to her fucking him again. What could I say. It was clear she was going to do it whether I liked it or not.
