Company president Yuu Hironaka is young but runs her own business, and while she appears strong and composed on the surface, she actually has a very fragile mental state. To relieve stress, she keeps a male masochist in her office, using him to ease daily pressures—flaunting her business suit in front of him, masturbating with a vibrator to boost her morale. However, whenever problems arise, she quickly breaks down emotionally. In such moments, she turns to blowjob as a crutch. Sucking on the M-man's cock helps calm her nerves, but she often gets unexpectedly aroused, ending up selfishly indulging in pleasure. Her demeanor in everyday life is sophisticated and urban, striving to balance work and personal life, yet ultimately struggling to control her own emotions—the contrast only heightening her allure.
