A female office worker on a business trip secretly indulges in masturbation, unseen by anyone, in what appears like an erotic ritual of suppressed desire. Forty women, alone in private rooms after work, tremble and desperately climax repeatedly—an expression of pure pleasure enjoyed without concern for others. The strong sexual desires of these working women are fully unleashed in this hidden space. Freed from tense meetings and unpleasant clients, they skip the shower and casually begin with "First, let's have a drink!" Their honest, uninhibited selves exude a strangely captivating charm that draws viewers in.
