Sinful Sis presents a different kind of love triangle. When Big Sis Honoka arrives at home with a bag full of her brother Hirokazu’s favorite snacks and drinks, she’s unnerved to find an unexpected house guest named Akazaki, Hirokazu’s sexy classmate, who’s over for a not so innocent study session. Brimming with jealousy, Honoka shows her brother in the most explicit terms why he doesn’t need a girlfriend! Meanwhile, Akazaki hears the steamy goings-on in the next room and gets an idea! Will she leave the two sibling lovebirds alone or daringly initiate a threesome? To say that things get complicated is an understatement. Based on the controversial adult manga by Yuzuki N’.
