DORR-001 Guide my cousin on how to make love

Kanoko is a younger sister who loves her brother. In fact, she is a muted and lewd girl who acts as a girl behind the scenes. Hit my brother with his favorite aura and seduce him quietly. The brother couldn't bear it and took action against his sister even though he was from the same family. Moreover, what came out of my sister's mouth, who had such a cute anime voice, was an unimaginably silly voice. The two have crossed the line and can't hold back anymore, they search for each other all day when their parents are away.
