DASS-232 | A record of me creampieing my younger sister with all my desire for two days without my parents. Rimu Yumino

Her younger sister, Norimu, is shy and quiet even in front of her family, but she is actually very curious about sex and has feelings for her older brother, Hajime. One day, Hajime's parents assign him to watch over them while they go to a relative's memorial service. When Hajime tells Rimu about his feelings for her, he brushes her off, saying, ``We're brothers, right?''
