You are here for your weekly arrangement with your hot, brat sister - you pay her, and get to watch her do her yoga in her skimpy tight outfit. She takes your money with contempt and makes sure you know who is in charge, if you even try to touch her, she will tell your parents what a disguising pervert you really are. You are watching her perfect ass stretch up into the air with her perfect round ass cheeks just inches from your face when suddenly her back goes stiff. Suddenly the tables are turned. She is helplessly bent over in front of you with her back arched and her ass in the air. Will you be a good brother, or will you take advantage and teach her a lesson for being a lifelong bitch?
