Ayu, the secretary, appears elegant and poised on the outside, but in reality, she has a deeply masochistic personality. While indulging in masturbation alone in the empty office, she is caught by her boss and a male subordinate who have returned from an outing. The boss scolds her, saying, "So you're always doing such shameful things?" His words only heighten her arousal, making her already sensitive body respond even more. It turns out she routinely works completely naked, exposing her body without restraint. Even more shockingly, both her nipples and clitoris are pierced, each adorned with body jewelry—clear symbols of her extreme submissive desires.
