This is a true story that has recently occured. My wife Jill (not her real name) is 46 long blond hair, and a gorgeous body. She works out at the local gym 3 days a week (you know the one, its got FF in the name). We have been married for 26 years and up until last year both of us had never in our lives had sex with anyone else. Last year I suggested to Jill that she trys another guy by going swinging. She was not totally in agreement at first. Anyway we decided to go to a guys house and he was to watch. We had a code that if while he was watching she touched is cock it meant that she was happy for him to fuck her. You may have guessed that he did in fact fuck, and she loved it and we made a video. Since then Jill has fucked about six single guys and we have always made videos. The last one was good because I sat in the other room whilst she was fucked hard. About a month ago whilst were were making love one night whilst watching one of our dvds, I asked Jill if she ever fancied having a regular lover of her own. Thinking she would say dont be stupid, I was horrified and slightly turned on and said that she would like to. I'm not bad at fucking her, but I have noticed that these other guys fuck her harder than me and she loves it. I thought no more about this question and forgot about it. I noticed that Jill then started to go to the gym at nights as well as in the day. Last week I was having to go away on business, and told Jill I would be away all day. However when I got to work my meeting away was cancelled. Lunch at home i thought. I drove home at lunch time and noticied a car on the drive. Strange I thought. I tried the door of the house and it was locked. I was now a bit suspicious. Fortunately the key was not left in the lock on the other side so I quietly went inside. I heard voices and could see from the door that was ajar, that Jill was kissing another guy. I was livid and was about to make a scene when I thought, no lets see. I recognised the guy from the gy. He was black and well toned. They kissed for a while and it was not long before Jill got out his cock and started sucking him. Then I saw her spread her legs and guide his thick black cock into her. He fucked her for ages and she loved it. I left after 30 mins, locked the door and went to work. She does not know that I have seen her. I think I have opened Pandoras box and the lid has been thrown away.
