"Step-Sis Loves To Rub"

Your parents have recently fired the cleaner and until they hire a new one, they've told you and your step-sister to do the cleaning for now. Your step-sister is polishing the banisters while you do nothing but perv down her shirt. She knows what you're doing and makes a deal with you... if she lets you wank your cock over her tits, you'll tell your dad that she can drive his supercar!
