Miu, a teacher concerned about a truant student, visits his home only to find a trash-filled house. The student's father, a disgusting old man, drugs her and forces her to have sex. He defiles her pure skin with relentless fucking. She gets creampied in the trash room, has continuous vaginal sex with toys and aphrodisiac, gives blowjobs in the bathroom, and experiences reverse flow fucking. She even squirts while playing with toys and smoking aphrodisiac. In the end, she becomes nothing more than a fucktoy for the old man's drug-fueled rape.
