My step-sister tried to sneak out of the house today before she finished her chores. She was dressed like a total slut. Where do you think you are going? I asked her. Step-Mom left me in charge and you are not going out until you finish your chores. As a matter of fact, if you want to go out like a slut, now I am going to treat you like a slut. From now on, step-sis has a new chore to do, take care of my cock!
