I confront her

“Well, I guess you’ve already been fucked today anyway.”

“Why are you talking nasty to me?”

“I saw you.”

“How?”

“I came home a little early and saw you and the young stud fucking in my family room. Fucking on my couch.”

“What, are you just a pervert who likes to watch?”

“Is that really how you want to play this?”

“Why do you ask, so you can watch and play with yourself?”

The next thing I said got her attention, “You’re cheating on me. I’m going to divorce you.”
