A petite adult woman named Chihiro worries about a sick neighbor whose home has become a trash-filled mess. He exploits her kindness, lures her inside under the pretense of cleaning, confines her, and subjects her to drug-fueled sexual assault. Terrified and unable to resist, she is licked, penetrated, and conditioned into extreme sensitivity amid the garbage. Used whenever the older man wants sex, she loses control through repeated orgasms until her reason fades and she becomes his captive sex toy.
