The Little Bitch Sister Who Was Given An Aphrodisiac, Turned Around, And Made To Cum Convulsively With Her Legs.

Due to their parents' remarriage, outgoing younger sister Tsubomi and introverted older brother Satoshi became siblings. She hates her introverted, otaku-like older brother and bullies him daily. On her birthday, Satoshi gets a suspicious aphrodisiac from a friend and, to get back at her for her daily harassment, slips it to Tsubomi. She loses control of her body, her entire body becomes an erogenous zone, and she starts losing control of her bladder... Though she verbally resists, she can't fight the pleasure, showing an ecstatic face and cumming hard with moans...! #ChinP
