Tsumugi Akari helps her brother satisfy

My brother raped me. Since that day, my family has been torn apart. My brother caused a similar incident at his part-time job at the time he was arrested. After being released from prison, my brother masturbated day and night in his room without leaving the house. My brother's sexual desire is not as normal as it was back then. My mother was afraid of doing it again and told me. Tsumugi for the sake of the family treats his brother's sexuality.
