roleplay/jerk off instruction with cum countdown ending. Were you trying to look down my shirt again? You little pervert. You think I don't notice every time you see me walking around the house in a low cut shirt you go lock yourself in your room? I know you're jerking off to me. You want to see my tits don't you, you creep? I'll let you jerk off to my tits but only if I get to watch. You're not allowed to go hide in your room. If you really want to be a pervert and jerk off to your stepsister you'll do it in front of me.
