Your step-sister is visiting and staying in your old room. You go to hang out with her and she's in lingerie. Your parents are out for a while but you had no idea what this day would lead to. "Get out little bro, I have a real man coming over to fuck me. You wouldn't even stand a chance". It seems like she's challenging you, but either way it turns you on. She notices and eggs you on more and more. HOW were you supposed to resist? Ugh she's so hot!
