One day, Takeda, an office worker who loves butts, is ordered to train new employees at the company. He has to go to the office when no one is there because of remote work, and reluctantly trains the new employees. The new employee, Asakura, has an amazing butt! Takeda's butt switch is turned on at first sight, and he keeps staring at Asakura's butt while training the new employees. He eventually masturbates while looking at her butt, but he can't help himself and attacks her in the empty office...!
