Set against the repressive backdrop of the Showa era, the long-awaited sequel to the office lady's story finally arrives! Late at night, Nana returns home and sits at the kotatsu, reading an erotic novel alone. Stirred by its lewd descriptions, she gradually sinks into a lustful mood. Unable to suppress her growing desires in the solitude of her room, she naturally begins to pleasure herself. At the foot of the kotatsu, she lightly rubs her pussy and stimulates herself with her fingers, causing frustrated fluids to gush from her depths until her body twitches and convulses in climax. Suddenly, the black rotary phone rings. It's her company president, asking her to entertain a client. With a major contract on the line and a bonus double her salary, she can't possibly refuse her beloved boss's request. After getting her hair styled at the salon and finishing her makeup, she looks into the mirror and sees someone entirely different. The entertainment begins at the designated traditional restaurant. The client's president keeps offering her drinks, which she can't refuse, downing them one after another. As she starts feeling tipsy and slumps drowsily, the client's president and managing director exchange sly smiles. Taking advantage of her inability to resist, the two men begin groping her body. Though her mind protests, her body responds, moans slipping from her lips. When her forbidden inner flesh is tormented by a vibrating kokeshi doll, she screams in ecstasy and gushes a massive tidal wave. Repeated orgasms and the smell of throbbing cocks blur her consciousness, until she starts grinding her hips on her own. Each time her deepest core is penetrated, waves of intense pleasure surge through her entire body. And then, watching the man who just dominated her now collapse with a pitiful expression as he cums, she feels a strange sense of superiority. As her awareness fades, something inside Nana finally snaps... Witness the raw, unfiltered life of a woman tossed about by the tides of her time. With your eyes, with your cock, savor every moment.
