One day, Takeda, an office worker who loves butts, is ordered to train new employees at the company. He reluctantly ends up going to the office when no one is there because they are working remotely. Hinata, a new employee who is being trained, has a super beautiful butt! Takeda's ass switch was turned on at first sight, and he continues to stare at Hinata's butt while training the new employee. He eventually masturbates while looking at her butt, but he can't resist and attacks her in the empty office...!
