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

Kanoko, a sister who loves her brother dearly. In reality, she's the type of girl who does underground filth. She emits a 'I like you' aura and secretly tempts him. The brother can't hold back and lays his hands on his own sister. Moreover, from the mouth of that sister, who had such a cute anime voice, comes an unimaginable moan. Once they've crossed the line, the two can no longer stop themselves, seeking each other out all day long while their parents are away.
