You know where she's going. You know who she's going with. You know what they'll be doing. And you know nobody will spare you a second thought.
The days of her wanting you to be okay with it, and of coming home and letting you clean her up while she teased you with the details of the night are long gone.
She'll just come home, shower, and go to sleep, same as always now. No mean texts, no sexy pictures, no lurid details. Nothing.
You're a helpmeet. You're a flatmate. You're an ATM. You're not a cuckold, you are irrelevant.
So... don't wait up.
Go to bed. Catch up on some sleep. Do your duolingo. Binge watch that show you like. Binge eat cheetos while you play world of warcraft. Binge jerk to #loser porn. Get black doms off in chat rooms pretending to be her. Try on her clothes. Put something in your butt. Do whatever the fuck you want.
But don't wait up.
It'll hurt a whole lot less if you don't wait up.
This was my wife after her first time with her boyfriend. She told me she would be there for all his needs, whenever he needed her
This is based on a true story. When I first started telling my wife about my cuckold fantasies she got upset and thought they were perverted. However, over time she warned up to them. I think she started becoming intrigued when she realized that I was serious about being 100% faithful while she was free to do what she wanted.
