Ran Himeno's first-ever SM bondage release is finally unveiled! As a child, frequent relocations due to her parents' jobs led her to grow up introverted and quiet. After losing both parents in a car accident five years ago, her homeroom teacher, Ms. Tanaka, became her only emotional support. But her peaceful daily life is suddenly shattered, dragging her into a hellish existence. Bound by hemp ropes, subjected to creampie training, wax play, and forced to climax with toys, she gradually breaks mentally, completely dominated. Witness Ran Himeno's intense performance as she realistically portrays her first SM experience.
