Every Friday evening stepmom and stepdad go out for “date night” and leave your big step s i s t e r Ivy in charge. Normally she just takes the babysitting cash and heads to her room to ignore you all night. However, tonight your step s i s t e r towers over you, dominating the house. She sits you down on the couch and bends over, teasing you with her new mesh pants while admitting she found her dirty panties hidden in your room. Before you have a second to think your step s i s t e r shoves her ass in your face. You feel like the luckiest little b r o t h e r in the world when she tells you to start masturbating for her hidden derrière. You love being your big s i s t e r s’ little bitch.
