We had been involved with swinging before the children came along. After they moved out, we got to talking. Each of us had several affairs. Those were very toxic to our relationship. My wife had expressed her need for sex with well endowed men. We talked through a lot of things and decided it was better to be open about it. We both loved each other but we recognized that we would never be monogamous. We decided to start swinging again. We became involved with a local group of couples that also included a few select single men. At one of the parties, my wife became attracted to one of the single black men. He was a high school teacher like she was. Teachers and nurses are the biggest freaks. Soon after the party, we invited him to join us for a threesum. He was both well hung and a skilled lover for her. At the next few parties, they started going off alone. After one of the parties, she told me on the way home he had asked her to come to his house alone since they were on summer break.
She said it would be no different than going off alone at the parties. i finally agreed. When the day came, she left for his house at the same time I left for work. I couldn't concentrate on work. All I could do was imagine what was taking place. I got home from work early but she was not home. It was almost 8 that evening before she got home. I had a ******* and was resting on the lounge part of the sofa. It was obvious with her huge breasts that she hadn't even put her bra on. She pulled her dress off and stood in front of me nude with dried cum on her tits and cum leaking from her red swollen pussy. I asked her what happened. She told me she would tell me only if I would perform oral on her. I asked again and she told there was only one way she would tell me. When I finally agreed, she straddled me and put her tits in my face. Her nipples were as hard as stones. She told me to clean the cum offf her tits. . As I started to lick her she began to describe her day. When she was satisfied i had got all the cum off her tits, she sat on my face. During this she had several strong climaxes. Each time more cum was squeezed out. She finally climbed off. She let me fuck her but her pussy was so loose and sloppy with his cum, neither of us got much stimulation. She said now I had eaten his cum, I had accepted he was her bull and she would go to his house anytime they felt like. That was 16 years ago. Our relatioship change from us swinging to me being a cuck and her being owned by her bull.
After we retired and moved to Florida, he visits several times a year. I have to wait in them and i get the guest bedroom. Yes, things changed.
