Taketa, a salaryman who loves asses, was assigned to train new employees and had to commute to the empty office due to remote work. He reluctantly agreed to train the new employee, Asakura-san, who has an incredibly beautiful ass! From the moment he saw her, Taketa's ass switch was turned on, and he couldn't help but stare at her ass while training her. Eventually, he started masturbating while looking at her ass, but he couldn't hold back any longer and attacked her in the empty office.
