21-year-old Mio, a track and field athlete from a corporate team, once competed in the National High School Championships and continues to break records with her 170cm tall frame and long legs as a rising star in high jump. Her bust, still growing, has reached a voluptuous and sensual G-cup—unusually curvaceous for an athlete. With a face that appeals to older men, she has been in an affair with her coach who has trained her submissive body in BDSM. This highly erotic and captivating woman is thoroughly disciplined on camera. Outdoor remote-shoot humiliation in a skimpy uniform that digs tightly into her bare ass. Bound with rough rope forced deep into her pussy for restraint torture sex. Oiled-up massive breasts used for titty fuck and anal licking service.
