Trudy and I had joined a swinging group and were the fourteenth couple and shortly afterwards a fifteenth couple joined. All the couples were either in their thirties of forties. The format seemed to always bee the same. We would meet at Colin's place and the women would pull a number and put it in a bowl and the men would pull a number and whoever you chose that was who you would be sleeping with that night. All members were checked before they joined and all were pretty good looking. The night in question that I am telling you about, my wife was picked by Colin. Trudy had slept with him several times before and was definitely happy with the pick, although she would have been happy with any of the men. I pulled number eight and discovered that it was Pearl's number. I was excited as I had not slept with her before and I had fancied her for some while. She was a small sexy little bundle of fun and several of the other men had praised her as a great fuck and good fun. The only other sort of rule was the men went to the women's home for the night. I was told that was because it made the women more comfortable in their own surroundings. I drove Pearl back to her house and as we entered the house she turned to me and kissed me. As we kissed she had her tongue in my mouth and her hands in my trousers. She was definitely a live wire. When we broke for air she dragged me to her bedroom. As I undressed she went into the En-suite bathroom and when she emerged a few minutes later she was in a sexy baby doll outfit. I was naked in bed and she quickly joined me. We kissed for quite a while and as I fingered her soaking wet pussy she stroked my cock. Then she pushed me onto my back and swiveled around and planted her pussy on my face and took my hard cock into her mouth. She was sucking as if her life depended on it. I was worried she may have me come to early and spoil the chance of a good fuck. I was sucking and licking her pussy, paying special attention to her clit. I must have been hitting the mark as Pearl was groaning quite regularly as I licked her. To my surprise Pearl asked what my favorite position was and I told her that I loved doggy style. She told me that was her favorite as well. I soon had her on her hands and knees and mounted her from the rear. Pearl was obviously enjoying herself as she was moaning and groaning non stop as I plowed her pussy. I was pleased that she came first and even more pleased as I hung on and finally came with Pearl as she came for the second time. We were both exhausted from our coupling and cuddled down under the duvet. It couldn't have been more than twenty minutes before Pearl was stroking my cock again. Then she turned around and sucked my still soft cock into her mouth. She was good. I would defy any red blooded man not to get hard if Pearl was to suck him. Now I was hard Pearl turned back around and straddled me and lowered her pussy onto my cock. As she started to ride me she lifted her boobs out of the top of her nighty and as she rode they were slapping into my face. I found that incredibly sexy and was soon sucking on her nipples as she rode me. We must have fucked for the best part of twenty minutes and just before she came we were kissing and that seemed to push her over the edge. Her coming triggered my own climax and I pumped a second load into her pussy. Then exhausted again we lay kissing and cuddling. I slowly dropped off to sleep. I woke with my normal morning woody. I fucked Pearl again. This time I had her feet over my shoulders as I slammed into her from above. How pleased was I that I managed to take Pearl through one climax to a second when I came again in her pussy. It was almost ten a.m. and the rule was that the man had to be out of the woman's house before ten. I was dressing quickly to allow enough time for another nice kiss before leaving. Was I chuffed when Pearl told me that she hoped that I pick her again soon. I drove home and remained outside as Colin hadn't left just yet. He kissed Trudy on the doorstep and gave me a wave just before he climbed into his SUV and drove away. Trudy and I spent the rest of the morning in bed kissing and cuddling. Neither of us was pushing for sex, so it was just a sexy time. That was just one of our many swaps. The couples have all kept in touch over the last year as contact has been out of the question. We have learnt that two of the couples have become pregnant and one has already had the baby. The other is due shortly.
