I knew that you’d come back for more. After everything I’ve done to you, everything I will do to you, you simply want more. I want you to stroke, knowing that each time you do, you belong more and more to me. This is where you belong, isn’t it? Making sure everything you do in life brings me pleasure. Mistress’ pleasure is all that matters, and I want you to fantasize about me when you’re with your wife. Fantasize about me in this red lingerie. Fantasize about getting a glimpse of my perfect pussy and hairy bush as I play with the edge of my thong. Fantasize about my perfect ass and how you’d do anything for a chance to worship it. I have complete control over your life, over your relationship, over what you think about when fucking your wife. Anything I allow you to have is just that - an allowance that I can revoke at any time. 

 Maybe I’ll tell you to stop fucking your wife…just for fun.
 Maybe I’ll tell you to stop touching your cock…just for fun.
 Maybe I’ll tell you to “accidentally” moan my name in bed when you’re with your wife…just for fun.
 And you can have fun as well…in marriage counseling! 

 Do you see how fucked you are? I can burn it down at any time I want if you stop pleasing me. But you wouldn’t dream of doing that. Not with the way my hips sway. Not with the way my legs spread and my fingers tease over my tiny thong. Not with the way my words binds your will to mine. Do you think your wife knows what a complete degenerate you are? Do you think she knows how hard it makes you to send me your hard earned cash? I know what to say to trigger you into compliance - and she can’t even get you to do the dishes! Your wife will never know what you are, never know how to please you. She’ll never know how I own your sex life, your cock. Unless…I decide to tell her. 
Just for fun.
