Will She

I don't know. You said flirt and kiss but did you say anything about her taking it further? How OK would you be if she sucked his dick or even fucked him? If you want this than you'd better not get angry with anything she does. Be supportive when she comes home tonight and if she reveals that she fooled around tonight tell her how beautiful she is and how much you love her.

You need to work it from the other angle.
I was having trouble with my wife and her permisteral trainer. The guy was obviously after her and he was a real jerk. I worked hard to get her to another gym and to working out with a guy I discovered, who, by the way is absolutely grogeous himself. He's movie star good looking. I figured once I got her away from the jerk, it would only be a matter of time before I became a cuckold to a young beautiful hotwife who was fucking her trainer.
I overheard her telling a girlfriend about the affair and how she was infatuated with her new trainer. And a friend from the gym told me they were hot and heavy. But I was only hearing about their affair second hand. So I approached the guy very diplomaitically and told him that I had found out that my wife had a crush on him and wanted to fuck him very badly. I never let him know ttat I already was awaee of the affair.
I made him aware that if he would fuck her it would be a tremendous thrill for her and that I would not interfere. To solidify the deal I paid him a bonus and rented a suite at a hotel for the weekend for them. I asked him to fuck my wife but not tell her that I either knew or encouraged it.
He was elated. He never let on that he had already been fucking her, but he couldn't hide his pleasure at not having to hide the relationship...and also how pleased he was because I was going to pay him bonuses and expenses. It has been expensive, but it only took thirty minutes to turn a secret love affair into a completely submissive relationship by simply approaching the bull.
