Here is sort of a rough draft of the idea;
"Dad, look at this video"
"Son, don't show me that. That's porn! you shouldn't be looking at it on your phone"
"You look at it on your phone"
"No, I don't"
"Dad, open twitter and show me.."
"Okay, maybe I do but that is none of your business. I don't want to share porn clips with you."
"This looks like mom."
"Son, you shouldn't be looking at Milf porn (checks phone), oh my God, that is your mom"
"You sure?"
"Yeah, she has that same tattoo on her hip..." (watches intently)
"Who is that other girl with her?"
(looks like the sister but neither want to acknowledge it. They can't see her face. She is clearly sucking men off and gurgling."
Dad Confronts wife.
"What? how did you find that video?"
"It doesn't matter how I found it. It's you. We've been married 19 years, Sophia. How can you do this to me?"
"Don't act all shocked. You and I haven't had sex in six months."
"That doesn't give you a reason to cheat."
"It wasn't cheating. It was just money. It meant nothing."
"Money?"
"Yeah, how do you think we could afford to go to Cancun last summer? or Miami THIS summer. I have an onlyfans account. You never questioned how I can afford to pay for things but I don't work or ask you for money?"
What happens next?
