That scene burns into my mind and never leaves. No matter how many times I put it out, the passion that springs up does not subside. Satoshi was indulging in masturbation without knowing how to deal with the excitement he had never experienced before. A scene that made Satoshi crazy. It is the defenseless naked body of my mother, Riku, who was taking a bath. It was a wet breast. The moment I witnessed something, something broke in Satoshi, and Riku's existence changed from a gentle mother to a sexual object. I want to see my mother's chest again. I want to touch, I want to smoke ... Driven by intense emotions, Satoshi invades the bedroom where Riku is sleeping.
