Your step-sister is crazy hot. Especially in that tight school girl uniform. You just can't help yourself. One day she finds her panty drawer hidden in your room, she confronts you and decides to pay you back instead of telling step-Mom and step-Dad. She starts degrading you, telling you to sniff her ass and lick her panties. She stuffs them in her tight wet pussy, teases you with her asshole and tells you all about fucking her big dick boyfriend. You're jerking off hard with your nose pressed to her butthole when she tells you to lay down so she can piss all over you. Thats what pervert step-brothers get.
