She pulls the yoga pants down showing off her buttcrack, teasing you about how your friends all think she is hot too and tells you that they love jerking off to her big pretty ass! You get hard from this and your hot sister starts giving you jerk off instructions as you play with her penis and worship her ass! She tells you to put your face in her ass cheeks and you do as you're told, smelling and worshiping her ass while stroking your penis for her. She shows off her butthole to you until commanding you to cum on her butthole!
