Struggling to advance in her career as a diligent office worker named Yuma Sano is about to have her professional ambitions derailed—or boosted! Instead of gaining valuable experience through mundane tasks at workday after workday—all while enduring the sharp tongue and lecherous stares of her boss—Yuma finds herself trapped by an urgent deadline. Forced to stay late to meet his demanding standards,
her abrasive superior makes his move. Knowing Yuma craves upward mobility in the corporate ladder-climbing game she plays so hard at winning (and losing), he offers her a deal: career advancement in exchange for serving his every whim. Initially resistant to the proposition from this crusty manager type,
Yuma’s resolve quickly melts away when he begins teasing her most sensitive spots. The rush of pure sexual pleasure proves too tempting to deny. From that first reluctant agreement, she becomes addicted; each overtime shift now means another opportunity for her wicked boss to help her 'climb the corporate ranks' through intimate encounters.
