A special solitary confinement cell exists within a certain prison, managed solely by the warden's daughter. She possesses intense sadistic tendencies and selects prisoners she finds appealing, locking them inside the cell. By controlling their food, water, and even ejaculation, she psychologically dominates them, ultimately reducing them to disposable human toys. Initially defiant prisoners gradually succumb to hunger and mental manipulation, eventually obeying her every command. Throughout this process, they are treated as sex toys or dolls, and ultimately forced to eat her feces. This form of domination operates as an unspoken rule within the prison, never discussed openly. This work depicts the intense fusion of psychological and sexual control as a female guard slowly breaks down a prisoner's mind and achieves complete domination.
