Your sister finds her panties in your room and confronts you. You can't help getting turned on as she yells and calls you names for being a sick little pervert. She noticed you're hard from it and toys with you more, rubbing her dirty panties all over your face. She takes it one step further and makes you get on your knees so she can rub her ass and pussy in your face. She can tell how much you enjoy her stinky ass and tells you to wank yourself while she rubs her ass in your face.
