I've noticed that when I go to wash my dirty satin panties, they have CUM ALL OVER THEM. Stepbro, I know exactly what you've been doing. You've been jerking off with my dirty, satin panties. If you don't want me telling stepmom and stepdad, you will do all of my chores and homework. Not only that, but I am going to have you wear satin panties every day under your boy clothes. I am going to have you send me photos at random to prove you're wearing my panties at all times. If you try to trick me and not wear the panties, I am going to make your life a living hell, got it? Here, you get to wear these dirty, cummy panties first!
