Nephew

A short version of a long story when I caught my wife fucking her own nephew. Her sisters son.

He was17 at time when I caught her. Idk when it started for all I know it had been going on for years. I should of walked in and caught her when he was plowing her. But I was shocked and I left coming back later and confronted her a week later
I got off work early. The line I worked in foundry went down so it was January cold as hell. My wife was 38 at time brown curly long hair petite she was short only stood 5 foot and lucky to be 110 lbs. she had a cute small ass narrow hips almost Tom boyish but 36 c cups made up for it.
Her nephew came over often my wife and her sister was close and I never thought much of his closeness with my wife.we had a daughter in college so she was alone most nights. I knew he was over that night I had talked into her earlier she called me on break and said they was watching
Yellowstone together later.
I tried calling on way home to see if she needed anything but she never picked up. I walked up to house it was snowing cold
It was 8 pm pitch dark I could hear tv on and then I heard my wife say oh god just as I was about at door. I should of walked in and idk what would of been said. But I go over to window and look in and I couldn’t see. It look like she was laying on couch I could see clothes on floor but the back of couch hide the occupants.
I could hear now she was lying down I thought she was moaning and so I wanted to see like any good husband lol I figured she was masturbating
I go around corner and look it side window
Now I wish I was prepared but I was shocked.
Hindsight I would of watched kept my mouth shut and set up camera later to catch her again but I look in and see her nephew ontop of her her legs wrapped around him up on his back her arms around his neck as he drilled her.
She was in the throes of a orgasm when I saw and pushing her hips up to meet his violent thrust
I looked only for a few seconds but I saw enough. I was shocked. And embarrassed at time.
I left and came back later and they were watch Yellowstone I believe came on at 9 at that time.
I was too embarrassed to say anything I just told her I got sent home early for breakdown. I say nothing and watch Yellowstone with them. I didn’t know how to handle it. She actually wanted to have sex the next morning and I found myself turned on more than ever.
So I stay silent. I keep a close tab on things over the next week and she called me on my break the following week like always and she said Tony was coming over again to watch Yellowstone with her.
I asked why don’t he watch it at home. She said it’s a fun series and the both love it so they watch it together.
I couldn’t get off work so my imagination ran wild. I became jealous and I confronted her the next day. I should of said I watched her or saw them but I just made the accusation.
Funny thing is I was turned on by it and didn’t realize it at time.
Well this blew it because he didn’t come around for the series anymore atleast not that I knew of she never said anything about his watching it with her . I didn’t bring it up because after I excused her she told me I was sick and it could start a fight. And what’s the point in that she would deny it.
It’s been a year idk if she has been with him only that one or several times since? Or when it started
All I know is that the few seconds I watched him drilling her and the intensity of it a young nephew her own family the taboo idk. But it still makes me rock hard. I secretly hope she is still fucking him. I want to catch them in act again so bad.
Our sex life I believe is better it seems more interesting and I certainly can’t fuck her without picture her nephew pounding her.
