VRTM-050 The temptation of the lustful older sister

The mother and her two little children were having a prosperous and happy life until both children became adults when everything changed. The beautiful older sister Inoue and her younger brother have both grown up, especially the older sister has had a successful puberty: her big round breasts and plump buttocks make her younger brother increasingly fond of her and sometimes even in love. His mind had some dark thoughts. The older sister is becoming more and more mature, taking care of her mother and younger brother thoughtfully. Everything started happening on the day when her desire increased. She didn't know what to do, so she masturbated to satisfy her need. Unfortunately, her younger brother discovered it. Like a grown woman, the next day she boldly propositioned her younger brother because after so many years of being together, she also knew that he had been paying attention to her for a long time. And so the incestuous love story between them progressed further and further in secrecy from the mother.
