Maki Hojo is the feared senior accountant who speaks her mind to anyone, enjoys the president’s trust, and remains secretly admired by younger employees. Calling a man in after work, she exposes his use of company expenses at blowjob bars. Expecting dismissal, he instead hears, “If you get relief at work, you won’t need to go,” as she begins stroking and sucking him with technique far beyond any worker. He becomes the human vibrator for her frustration with an absent husband, receiving weekly oral under the excuse of overtime before they continue their affair at a hotel until the last train.
