I can't believe my favorite cute little sister, Kanko, makes such a vulgar squeal...

Kanoko is her younger sister who loves her brother. In fact, she's a shy, lewd girl who works as a girl with a secret account. She secretly seduces her brother by exposing her aura of love and love. The older brother can't hold back and tries on his younger sister despite his family. What's more, it's hard to imagine that it came out of my younger sister's mouth, who had such a cute anime voice. After crossing the line, the two of them are no longer able to stop, and they seek each other all day while their parents are away.
