This role-play is performed by adults. Kanoko is a younger sister who loves her brother. In fact, she is a sullen and lewd girl who plays dirty girls. She secretly seduces her brother by giving her a lovey-dovey aura. An older brother who can't stand it and puts his hands on his younger sister even though they're family. Moreover, I can't even imagine what came out of my sister's mouth, who had such a cute anime voice. The two of them have crossed the line and can no longer be stopped, and they spend all day longing for each other while their parents are away.
