You catch your new stepsister taking pics to send someone and decide to use it as blackmail to make her undress for you. First she starts out acting bratty but slowly becomes more embarrassed as you demand she take more and more off until she's naked and begging you to leave her alone. You make her show off her body to you, spreading her legs as she sits and getting on her hands and kneels to show off her ass to you. After you're satisfied she demands you leave but not before giving you something else to blackmail her with and getting her panties to keep quiet.
