On the surface, he appears to be a Kokoro stepfather, but behind the scenes, he is a crazy voyeur who relentlessly stalks his high school daughter. He licks her body with stinky saliva, rapes her unconscious, and has sex with her without a shred of Kokoro sense. His cries of "Please stop!" are in vain, but they do not reach his mother. Even though she hates him and finds it disgusting, her body automatically craves his dirty dick, and the daughter, who has become her stepfather's personal property, gradually falls into depravity in both body and Kokoro... "I'm sorry that you felt so good, Mom."
