21-year-old Miho works as a system engineer, intensely focused on her job. When she's alone at the office, her right hand naturally starts groping over her uniform, eventually sliding down to her pussy—her work style is incredibly erotic. Because she's so dedicated, the stress has built up immensely. Even while at work, she unbuttons her blouse, boldly spreading her legs wide to fully embody ecstatic arousal. In the sex scenes, after playful intimacy in the bath, she keeps her high-leg swimsuit on while fully exposing her pussy, showcasing her mature allure to the fullest.
