My wife, Theresa, and I have been happily married for 20 years and in our mid 40s. One of the fun things we did together was to participate in a mixed bowling league which was mostly couples. Our team consisted of the two of us and another married couple. Most every week, Theresa's friend Diane's team was in the lanes next to us. Diane is an attractive short woman with long dirty blond grayish hair. She's the same age as us and has an incredible ass that I love staring at when she bowls. She also has the most pale white skin which makes my fantasy with her and Jeff that much more exciting. Diane was divorced and shared her team with a married couple and an attractive slim older black gentleman named Jeff. Jeff was also single since his wife had passed away a few years ago. We would have fun each week with Diane and Jeff joking around and drinking. Most nights after a few drinks, Diane would put her hands on Jeff. Rubbing his arm or leg, hugging when they made a strike, things like that. I noticed my wife joining into that touching of Jeff also a little more each week.
Even though Theresa and I had a great marriage, we were never on the same page sexually. She is very conservative. I am adventurous. If it were up to me, we would be swingers hosting orgies. I love porn and I am into pretty much anything. She will watch very basic couple porn while we are having sex which I select the clips. The funny thing is while she is conservative, she is amazing once she gets going. She loves sucking cock and is very good at it. She takes her time. She lets me cum on her face or on her large breasts. I can always make her cum several times by licking her pussy. Fucking is not the same thrill for her. I do it but it's mostly for my enjoyment. Even though I have an 7 inch cock, I don't think it's big enough for her. She has a body built for sex. She has short dark hair which never gets in the way during blowjobs, big breasts which are great for tit fucking, and a good ass that' makes a nice slapping sound when I fuck her doggystyle. I just wish she would show more interest because I feel like there is a sex monster in there.
I suspected that Diane and Jeff had been having sex in the down low. I would jerk off imagining her sucking what must be a large bbc given his body build. I could see him fucking her doggstyle with her ass bouncing on every thrust. I also suspect that Diane told Theresa about him and his huge cock which is why Theresa is now flirty with him. I have always wanted to watch another guy fuck Theresa but I know she would never go for it. However, in this situation, it might just work. I need to help facilitate it.
At this week's bowling match we were going against Diane and Jeff's team. Things got real friendly between the 3 of them. Diane and Theresa were all over Jeff. Some of the other guys noticed it in the bowling alley and well they didn't approve. Jeff also saw that and steered away from Theresa some. Jeff and I talked and I told him I was okay with he and Theresa being friends. I told him that she really liked him and that made him smile very wide. He also admitted he was very attracted to her and told me what a lucky guy I am.
A few days after that night of bowling, I noticed on Theresa's phone a text conversation she was having with Diane. Diane mentioned that she could feel Jeff's cock in his pants the other night at bowling. At first she accidentally touched it then she did it intentionally and he did not stop her. She also sent a few random bbc pics with comments like she thinks Jeff has a cock like this. This told me that maybe Diane and Jeff had not been fucking. I checked Theresa's google history and I saw she had been searching out images of black cocks. This was very exciting to me because this plan of watching Jeff fuck Theresa might actually happen!
This weekend Theresa hinted she wanted a long sex session. I knew what I needed to do. I found some good interracial porn for us to watch. When the time came, we went upstairs and I started up the IR porn clips. She stared at the 55" tv with that Ir couple kissing and said "oh, this is different ". I could see the smile on her face. I just said, "I see you like this". Theresa quickly replied "yes i do, he is VERY cute" while she watched the woman in the clip suck and stroke his big black cock. With all this excitement, our sex didn't last long. Theresa was dripping wet when I started licking her pussy and she came hard right away. I also came early in her mouth while she had one eye on the tv.
