I Decide To Share My Wife

I’m two years older than my wife. I have a good job, nice place, and two sons. We had children quick and my wife wasn’t working for seven years after marriage. We made friends with another young couple so my wife keep their two daughters for three years to get some extra money. We always were wild in our sex life. The husband is mostly the one to pick up their children when he got off work. I discovered they were having sex sometimes by luck one day. I was off work that day when he came to pick up his daughters. We all visited but told him I had to finish my project in our back yard. I got up went out back into my shop. I quickly remembered I forgot something so I went back toward the house. As I passed a small side window to our garage I saw them. They were heavy kissing, he was squeezing a breast and then put his hand and started rubbing between her legs while she partially raised her leg. She saw me looking at them and pushed him away. I went back to the shop. After about 30 minutes she brought our boys outside to play and came to talk with me. My wife was crying so hard she couldn’t even talk. I asked her to calm down and we would talk later. She slept with the boys that night. The next day when I got home from work, the husband was waiting while kids where playing to talk with me. He was very apologetic. He explained hardly any sex from his wife. She is very overweight and has little self respect. I asked how it started. About 15 years ago his wife came by after getting off work at lunch got their kids and our kids and left to give my an afternoon break to my wife. When he arrived to pick up kids like usual he slightly knocked and entered as usual. He said he thought kids must be in back yard and was walking to back door and heard my wife in the bedroom. She was on the bed masturbating. He approached her and said hello. He said she tried to get up and get clothes on but he wouldn’t let her. She tried to resist but finally gave in to them having sex. I asked how often do they have sex. Sometimes once a month sometimes three times a week when a safe opportunity presented itself. My wife and I hadn’t talked yet because of the boys so when they went to asleep we went to the bed room and she started crying. I started giving her a hug and she held me tight. After a while I pulled her gown off then her panties and screwed her as hard as I could. After very good satisfied sex for both of us she shared honestly the same things her lover told me. Her weak moment she was embarrassed being caught frigging so she gave in to cover being caught. We talked about him not getting much sex from his wife. We talked how both families were best of friends and depended on each other. I asked honestly and asked did she enjoy sex with him. After thinking a time she said she enjoys sex with me best in all honesty because she loves me with all her heart. My wife admits she enjoys the physical sex with her lover but will easily stop. After more talking I said she could continue sex with our friend. I know how important sex was to myself ,so our friend must hold sex important. I told her to tell him this tomorrow. Only rule I had was I was to be told when they got together I was to be told before or afterward, so I could get a feeling from it. For two weeks or more I kept my wife screwed raw. After a month I was home one day and out back with the 4 kids when he came by. I told him to lock back doors and I would entertain the 4 kids in the backyard.so go for it. After about 45 minutes he unlocked back door got his girls and went home. I went to bedroom saw my wife still trying to recover. She looked at me and said WOW. I wanted sex that night but she told me she was really sore. For ten years she served mainly me but had sex with him often. He started complaining about sex things to her (age). So she stopped sex with him. I hope to get them back going on some occasions but she says she only has sex with me now.
