JUC-377 Matsu Sumire: Complete Private Tutoring Madonna

Sumire is living alone in an old family home, timidly afraid of her older brother Ichiro. One day, while visiting his house, she enters a shed in the yard and becomes locked inside. Suddenly, Ichiro appears before her with a cold, cruel expression. As a child, he was abused by their mother and confined in that same shed, and he has long harbored twisted feelings of obsession toward Sumire, who resembles her. Now, he begins psychologically and sexually dominating her through private 'tutoring' sessions inside the locked shed.
