My girlfriend had dumped me. It was my own fault she had caught me fucking her sister. I tried to go out with the sister but she also dumped me. I was now going through a dry spell. I met up with Curly my mate and his girl Jean. She was a looker and I had asked Curly how he managed to keep her. "Easy," he said, "She can see who she likes and so can I, but at the end of the day we are always together." I was confused and asked did he mean that they both fucked around. His answer was a yes as he gave me the biggest smile. "So if she wanted she could fuck me?" I asked. That was another yes and he said that if I wanted he would put in a good word for me. To cut a long story short two nights later I was fucking the shit out of jean. The extra practice with other men hadn't gone a miss. She sure knew how to please a man. Not only did she look good, she fucked good to. A few nights later I asked Curly if he was ok with me fucking her. He said, "Yes, knock yourself out, but just remember that she's mine." After that I would hitch up with Jean every once in a while. Then I met Shona. She was everything a man dreams of a real stunner. Like Jean and Curly, I wondered how I was going to be able to keep her as we had only been seeing each other for a week and already other men were hitting on her and even in front of me. I asked Curly how he came to the arrangement he had with Jean and he said he just sat and talked it out with her. He asked did I want Jean to talk to her to set the ground for me. I accepted his offer and we arranged to meet up as a foursome date out. We went bowling. I'm not sure when Jean spoke with Shona, probably one of their toilet breaks that women have. We were out bowling and it was the girls against the boys and it was about to be my turn. Shona whispered in my ear, "Yes you can fuck other girls if I can fuck other men." My bowling ball nearly ended up on the adjacent lane. Later after the girls won. We went to the pub near our homes. Jean whispered in my ear, "Time for bed big boy." I found myself walking Jean home and Curly doing the same with Shona. It was a little hard to concentrate at first fucking Jean, knowing my mate was fucking my new girl. Afterwards Jean kicked me out saying that I needed to be with Shona for the end of the night and Curly would be home shortly. After that first night it wasn't a problem seeing Shona go off with other men and she seemed ok with me going with other women. We always ended up back together. Curly and Jean had married quite a while back and seeing how happy they were and how much I love Shona I asked her to marry me. Her only question was would it affect our arrangement. I told her not if she didn't want it to. Four months later we were married and although a little unconventional Curly and Jean came with us on our honeymoon. Up till now, although I knew that Shona was fucking other men, I had never witnessed her doing it. That all changed. Our first night Shona and I had our traditional wedding night and fucked most of it away together. The next night we swapped with Curly and Jean, in the same room and even in the same bed. I found it to be a great turn on and Jean felt the benefit of my added excitement as I fucked her silly in front of my mate and new wife. The third night we hit some bars. We had barely got into our second bar when the girls were being hit on by a group of lads. Jean seemed less keen on them than Shona, but stayed with Shona as there's safety in numbers, and numbers there were, the group of lads were up to seven. Curly chatted up a pair of sexy local girls and suggested that we take them back to his room. I was a little concerned for Shona and Jean. Curly said that they would be ok. I wasn't quite so easy going and asked Shona if they would be ok. She told me that Curly and I should use Curly's room and if she and Jean decide to sleep with any of the guys they would use our room. Reluctantly I went with Curly and the two girls to his room. Thoughts of Shona and Jean evaporated when we had the two girls naked on all fours on Curly's double bed and taking turns with each girl. After a second round with the girls where we chose one each and settled in for a good fucking session, I started to worry about Shona. Curly was also beginning to worry about Jean as it was fast approaching midnight and Jean hadn't arrived back yet. We got rid of the girls and went to my room. There were a few lads hanging around outside, but it was what we found inside that shocked and stunned us. The first thing I saw was jean on all fours sucking a cock whilst a second pounded her pussy. As I got closer into the room I saw Shona. She was sat on one cock and bouncing up and down on it whilst sucking a second and wanking a third cock. There ware two more men in the room with their cocks out slowly wanking themselves as they watched jean and Shona servicing and being serviced by their mates. The two men realizing that it was our wives put their cocks away and left. Shona and then Jean both took cum in their mouths. Shona was quick to slide the final stiff cock into her mouth and he came almost immediately. Then the two fucking them came one after the other in our wives pussies. Slowly one by one they dressed and left. Jean and Curly left shortly afterwards. Shona just lay there with cum oozing from her fanny and cum on pretty much everywhere else on her body. She got up to go for a shower. I decided to remove the quilt as it was covered in cum and just sleep on the sheets below. Shona joined me and we cuddled and went to sleep. Next morning Shona asked if I was upset or annoyed to find her with so many men. I told her it was ok and was within our agreement apart from keeping time to be back with me. She apologized. The rest of our time away both Jean and Shona got fucked almost every night. Curly and I, being men, have a tougher time pulling women than what women have pulling men, so although we did pull several times, we spent more time watching our spouses getting fucked. I was beginning to wonder what had I done in marrying Shona. She seemed insatiable. Back home wasn't much better, and the rule of being home with me also went by the board. She had also dragged Jean into bad ways and although she always got home, she was occasionally late. Finally it got too much when she had four men in our house and in my bed. They took turns with Shona until four in the morning and I'm pretty sure that had I not kicked them out would have gone on for considerably longer. I told Shona that I had enough and it had to stop. The following evening she had two men with her when I got home. I kicked them and then Shona out. Not only did I find myself single, so did Curly as he had kicked jean out. It was some time before I got back in the saddle and that was with an ordinary looking woman called Sally. No more swapping or free spirits just one on one. Another thing, I will never marry again, the cost of getting rid of Shona still haunts me. As for Shona she married again and the poor sucker is getting the same treatment that I had, loads of men in his bed. Never again.
