I find this to be a very interesting topic with extreme yes answers or hard no's. I am now bi in my late 40s and it was more of an evolution thing. I was always what I thought as straight but very sexualy charged. And attracted to women that had a high sex drive. This always went bad until my second serious relationship, after couple of breakups from each cheating we tried an open relationship and some swinging. But that didn't last and we broke up because we just weren't a good fit. Then I met my wife that I have been with for many years and we came into the relationship with an understanding. She is my best friend and swinger partner and my goal is to satisfy her in every way. We have had our share of swinging and mostly 3somes with other men. (I can barely keep up with her and 2 nymphos kicks my ass) LOL. Anyways I love taking her to an awesome climax and totally satisfying her. And we eventually had our first BBC experience about 13 years ago. It was amazing how he rocked her world and she fucked the hell out of me for the next week. I had become so comfortable with men in a sexual setting with my wife I didn't think much about it. Then it happened I'm 69ing my wife getting her ready and her bull stepped up and started fucking her. I typicaly would slide out at that time and let him take over but I was a bit trapped and he said stay there and lick her clit. I didn't think much of it I had been close to alot of cock by now and this would make her cum in no time. We'll it did and she squirmed abit as she did I was able to catch my breath and get a great close up look that was amazing as she quiverd on him. She typicaly takes a minute to catch her breath before continuing. Before I new it in one stroke he pulled out and right into my mouth. I was quite shocked and tried to wiggle out but not before he got a few good strokes in. After that she wanted a smoke break and a *******. So I went and made drinks for every one and returned to the bed room and he went to cleanup abit before the next round. I sat next to her acting as it never happened and she straight out said so you got some dick. I didn't know what to say and sat there stammering and she said I want to see you suck his dick. She made the comparison of men watching women and said she really wanted to see it. She really pressed her desire. About that time he returned to the room and stood on the side of the bed closest to me. She put her hand on my back and pushed me toward him and said go on. I did of course, what may of been 5 minutes seemed like a half hour. Once I got him good and hard again he focused back on her and I took a smoke break and had a *******. I new this was a turning point but confused on what roll she and he was expecting me to take from here on out. Well it didn't take long to figure out. I stepped into the bed room and she said wait in the living room until she was done. I could hear through the walls them fucking the hell out of each other. I wanted to beat off but wanted to save for her. Not knowing if she would go another round with me after was driving me crazy. I had so many mixed emotions and my mind was thinking off every scenario possible. When they where done she walked him to the door and kissed him good bye as usual. She returned to the living room and with out saying a word got on her knees and sucked me off and said let's go to bed. We fucked like rabbits for the next few days and didn't bring up what had happened. But later in the week during dinner she said they had planned that before hand and hoped I wasn't mad. I said no. She said it was really hot and she was getting wet thinking about it and we fucked in the car outside the resturant before going home. Needless to say this happens frequently with her regular bull and she has sent me over to his place to suck him off when she has had to work nights a couple of times. I do not find white men attractive at all but I do find myself looking at black men now. I still like women and have sex with my wife all the time but find myself wanting black men.
