A man works as the caretaker of a women-only apartment building. His hidden obsession is sneaking into tenants' rooms late at night using master keys, indiscriminately assaulting sleeping women regardless of age—an extreme and depraved fetish. The kind, smiling man who greets residents each morning at the entrance is actually selecting his next target, mentally preparing for tonight's attack. This time, his victim is Asakura Yura, a busty G-cup office lady. Overwhelmed by sudden terror, she is completely helpless—forced into deep throat, tortured with sex toys, and then violently penetrated with vegetables taken from her refrigerator. She endures relentless abuse until he cums inside her. Unaware of the caretaker's crimes and fearing the video might be leaked, she cannot bring herself to report it to the police. Broken and humiliated, she has no choice but to move out immediately. This outcome suits him perfectly, as new targets keep arriving. Exploiting his trusted position as a well-liked manager, he continues to conceal his crimes successfully.
