Atama ga Yowai 〇〇 Kyonyuu Jitsujou wo Onaho Ikusei suru

A man with a predatory mindset encounters a young woman who is both physically developed and mentally weak. He sees her as an easy target and begins to manipulate her, slowly eroding her will and independence. Using a combination of psychological pressure and physical pleasure, he conditions her to rely on him completely, transforming her into a living sex toy that exists solely for his gratification. The story follows his systematic grooming and her gradual descent into a state of submission and dependency, as she loses all sense of self and becomes nothing more than a tool for his desires.
