When my wife and I first started dating at 18, she would babysit for a couple a few nights of the week. I’ve had this long time fantasy that the husbands work hours changed and he started coming home a few hours before his wife. As it turned out my wife, then girlfriend, was secretly crushing on him. One evening one thing lead to another and clothes started coming off. And he fucks her. It’s starts to become a regular thing. The evenings I’m visiting her, I’m asked to leave when he gets home. Or I have to listen from the living room as he fucks her in the spare room.
