Incompetent employee Sato repeats mistakes every day, drowning in endless overtime. While desperately searching for documents at work, he stumbles upon a notebook labeled "Common Sense Modification." Jokingly, he writes inside: "It's common sense to start the morning by giving your subordinate a blowjob to manage their physical condition." From that day on, his world changes completely. Early the next morning, as Sato arrives at work, his strict superior, Department Chief Satomi Mioka, appears before him. Without hesitation, she pulls down his pants and starts sucking his cock, making wet, slurping sounds. Overwhelmed by pleasure, Sato cums inside her mouth. Satomi calmly remarks, "Volume and taste seem perfectly adequate," then walks back to her desk as if nothing unusual happened. Sato realizes he is now the owner of the Common Sense Modification notebook.
He then writes a new rule: "It's common sense to have sex with male employees during overtime to provide mental care." He proceeds to dominate his busty, domineering boss however he pleases. After intense sex, he cums deep inside her. His power grows. He imposes new "common sense" on the arrogant junior colleague Mizuki Amane: "Greetings must involve deep kissing," and "Business meetings must be conducted in lingerie." Mizuki reluctantly engages in deep kissing and, when meeting time arrives, strips down to her underwear without protest. The client is furious, and the deal collapses. Sato’s position flips—he’s now in control. As senior, he begins punishing sex. He humiliates her with footjobs and blowjobs, watching her suffer with contempt, yet growing more aroused. He forcefully takes her from behind, refusing her protests, and finally cums inside her with a massive load.
To his smug coworker Ashina Honoka, he introduces another rule: "It's common sense to sit on a special chair equipped with a dildo during work hours." Honoka, who always looked down on him, is now forced onto the dildo chair, trembling and silently climaxing repeatedly. Unsatisfied, Sato adds: "It's common sense to have sex after climaxing from the dildo to properly relieve sexual desire." Honoka’s expression shifts instantly. Their chemistry is explosive, launching into non-stop, heated sex.
