Trouble-free whore

I don't let my wife refuse sex to other men. Sometimes I check it. I ask a man she does not know to turn to her with a request to suck him. She always passes this test successfully and sucks. My familiar men who know about the reliability of a whore use this when they want to discharge. And share information about the reliability of my whore with their friends. Therefore, lately my wife has to suck very often. This is great. It's frustrating that I can't always see it.
