Me (13 years old at the time): Dad, Mom’s cheating on you. I saw her making out with this man.
Dad: Listen here, princess. The guy’s filthy rich, and when you have money, it’s normal to have a hot mistress like your mom.
Me: But aren’t you jealous?
Dad: laughs
I was flabbergasted, lmao.


That doesn’t sound like cheating, that’s more like an open relationship. He knew about it and didn’t care.
I can understand how a 13 yo OP thought it was cheating though. They haven’t said they think it is cheating nowadays :)
The financial incentive makes it closer to pimping than swinging, at least potentially. Idk if the possibility the dad was getting something out of it besides, I guess, sexual pleasure stemming from cuckoldry makes it better or worse…
Or the mom is a sugar baby
As one who was in a similar situation to said dad person, back in the day: ¿Por que no los dos? 🤪
