You are going to get blackmailed-fantasy by your wife. Imagine if you could transform your boring sex life with your wife or gf, into something way hotter. I'm sure she knows things about you already that you wouldn't want getting out. And she has the power to spill your secrets to all of your mutual friends. She knows of even more people who are close to you than I do. She could probably ruin you more than anyone online. She could break you and ruin you. Imagine if you could turn her into the blackmail-fantasy domme of your dreams.
