New office lady Natsuki Kisaragi starts working secret part-time at a delivery health service to supplement her low salary. However, her boss catches her leaving a love hotel, exposing her side job, and she becomes subjected to workplace power harassment and sexual harassment. During document sorting, in meeting rooms, and at the staff kitchen, she endures persistent, sticky molestation from behind by her superior. Though filled with disgust, her body instinctively reacts to the unseen advances, betraying her emotions as she's drawn toward pleasure. The serious woman's lewd ass is gradually trained and corrupted by her perverted boss's hands. A pornographic drama blending workplace moral collapse with ass fetish indulgence. This work portrays the conflict between sexual harassment and pleasure in the office across five chapters.
