You know I love my step-sister and will do anything for her. You also know when you married my step-sister you also married me in the sense we are all friends now. Imagine my dismay to drive down a street nearby and see you exiting one of those massage parlors, those rub and tug places. I know what goes on there with those cheap ho-bags and skanks. So, is my step-sister not putting out enough for you that you have to go spend hard earned friends funds on a corner shop whore? I saw you wiping your hands of who knows what and you want to know something? I got pictures of you. That’s right, pictures. When you married my step-sister you married us. I never want my step-sister to find out about you cheating on her with some cheap rub and tug specialist. She would be devastated to know you went outside the friends for your sexual gratification. This is what is going to happen from now on. I am going to take care of your cock needs.
