Careful of what you want

First I am 60, my wife is 59. She is in fabulous shape, a very attractive woman, 5'8" 125 lbs 36B's.
Now I've a heart condition and suffer from ED.
Anyway she said I'd fanatized about watching her fucking someone, would she be able to fuck someone by herself first just so she could get used to the idea. Also she would feel safer if she could do it in our house. Well yeah. But also could I manage to be out for the night.
I sort of double down on it as that last part got me suspicious. I put up some spy cams because I didn't trust her to tell me the whole truth.
Point by point.
First they seemed more acquainted then she let on
They must have just kissed and rubbed each other for an hour. I was lucky if I ever got 5 minutes.
She initiated oral sex, she went after that cock, sucking, licking, paying with his foreskin and giving his ball sack a lot of attention. Even in our best years she hardly ever touched mine.
So when she wiggled around for missionary, she pulled her knees way back by her and guided his cock right in. In all my time with her I always to guide my cock in and she never as much as barely opened her legs for me.
Also she was extremely vocal with him, dirty talk, loud moans and groans and heavy panting. I'm lucky to hear a grunt.
So they roll around laughing and switch to her on top and you'd think she was a pro. I've ask her to get on top and it's "I can't feel anything or I'm tired" it isn't like I've got a small dick because when it worked it was above average and I'd gotten compliments from former lovers too.
When she finally had an orgasm I was shocked at the energy she released . Never that way with me and when she got in doggy she was begging for him to cum inside her.
Then they made out and napped in a spooning position, pretty sure his cock was inside her. They woke up and did it again. Have about 8 hours of them fucking.
Didn't piss me off that she enjoyed fucking him. It's very erotic and I've jacked off to it numerous time.
What pissed me is how she treated me for the past 37 years and I've already got plans to move on . Should have done it a long time ago.
