DORR-001 My beloved cute little sister Kanoko Sonoda, making such a vulgar sound...

Kanoko is a younger sister who loves her older brother. In fact, she is a sullen and lewd girl who acts like a backstage girl. Hit her favorite aura to her brother and seduce her quietly. A brother who can't stand it and dabbles with her sister even though she's her family. Moreover, what came out of her sister's mouth, who had such a cute anime voice, was an unimaginable silly voice. The two who have crossed the line can no longer hold back, and they seek each other all day while their parents are away.
