Ayaka Mizukami, a strict and uptight company compliance officer, constantly warns her colleague Yuya Takahashi about his inappropriate behavior with female coworkers. Tired of her lectures, Yuya decides to "teach her a lesson" by luring her into an empty meeting room for some hands-on "sexual harassment training." What starts as Ayaka confidently explaining company rules quickly turns into intense groping of her massive breasts, followed by escalating sexual acts that leave the proud office lady shocked, flustered, and overwhelmed by pleasure.
