My wife was entertaining her boss in our bedroom. She hadn't told him about me being a sissy yet, but wanted me to watch her. So I was hiding behind a curtain leading into her dressing area.
He'd just finished fucking her for the third time when she got up to use the restroom. That's when she whispered to me, "Sissy! I think he's gong to fuck me all night! You may as well go to sleep in the guest room."
