Kobayashi, a subordinate of the dominant and sharp-tongued Waka Misono, constantly suffers verbal abuse from her despite being competent at work. Seeking stress relief, he decides to call a delivery health service, opting for a referral-based "Acquaintance Delivery Health" recommended by a friend. When he makes the call, to his shock, it's Waka herself who arrives at his door—making him suspect a prank. Though her attitude remains assertive and commanding, she begins speaking in filthy, seductive tones, fully committing to her role as a service provider with aggressive, uninhibited performance. In the end, Kobayashi is completely overwhelmed and dominated, receiving an intense creampie after relentless blowjob and sexual service from the domineering, big-breasted seductress.
