I caught her
So I work 3rd shift. I sleep during the day and usually sleep in the spare bedroom. Just for the reason of her coming home and not having to stay out of the bedroom and that our bedroom during the day has way too much light.
So about 4 days ago I had woke up a couple hours early. I heard my wife come in the house. I guess she had company with her. It was a guy. Not unordinary because she sometimes has friends over. I heard him say, "When does he go to work?" She said, "Not for a few hours but the kids get home in an hour. It will be ok tho." He said, "What will?" She said, "We can go back in the bedroom." He said, "Your husband is here." She said, "So? Fuck him. Too busy with his butt buddy getting his dick sucked to fuck me. I need your dick in me...like now."
Then nothing. So I waited about 10 minutes and tip toed back to the master bedroom. He's laying on the bed and she is sucking his dick. All sloppy. He said, "You like that?" She said, "Mmm. Love this dick. I need it in me." She got on top of him and started riding.
I watched the whole thing. Dick in hand jacking while watching this guy fuck the shit out of my wife. I waited till she had cum and he had cum. She went limp on top of him. Then I backed up like 20 ft and walked back loud enough for her to know I was awake. I rubbed my eyes as I was walking into the room said, "Hey babe. What's up?" She looked over at me mortified and said,"Oh fuck. Honey. I...uh..." I said, "I saw the whole thing. Don't try to talk your way out of it."
