Hiring hypnotist to hypnotize your wife was the best decision you've ever made.
"Alright, you're all set. Your wife now thinks of you as her Master and will do whatever it takes to please you in any way you see fit. If she would happen to somehow break free of this trance, all you need to do is say the words "Obey Me Now" and snap your fingers. If you do so, there's no way she can possibly resist returning to this very trance. Right, Kim?"
"Yes, that's right. I am deeply hypnotized, loyal and obedient to my husband who is my Master. I will do whatever he commands. I will not disobey. I will always return to trance when he says "Obey Me Now" and snaps his fingers. I am powerless to resist."
"Very good. Now, please, have fun with your new slave and give me a call if there's any issues. Good day, sir."
