Kyoka Tachibana, a stunningly beautiful office lady with a killer body. Despite her gorgeous looks, she's actually a hardcore boss who berates her incompetent subordinates. While she's feared at work, she has another side to her. Once she gets home, she sheds her work persona and indulges in self-pleasure, stripping off her suit and falling into a deep sleep. Unbeknownst to others, she has a secret live-in partner - Kato, who she's been reprimanded by at work. Kato's career isn't going well, but at home, he transforms into a skilled lover, and Tachibana can't get enough of him. Their dynamic in bed is the same - Tachibana, the submissive girl, melts into pure pleasure under Kato's dominant lead, climaxing repeatedly. One day, they're left alone at the office late at night. Kato tries to seduce Tachibana, but she's still in work mode. Unable to resist, they end up having sex in a natural progression. On the desk... on a chair... Tachibana's intense orgasms lead Kato to cum inside her. It's a secret overtime session filled with forbidden pleasure.
