In a cramped, dimly lit classroom, Yuri Sato, the disciplinarian tutor, presides over her student's punishment. The student, clad only in a loose robe, stands before her, his breath ragged with anticipation. Yuri, dressed in a severe business suit, commands him to remove his robe, revealing his naked, trembling body. She orders him to masturbate, her voice steady and commanding. The student, his cock already hard, begins to stroke, his movements slow and hesitant at first, then building in speed and intensity. Yuri watches, her expression inscrutable, as the student's body tenses, his breath coming in sharp gasps. She waits, allowing the tension to build, before finally granting him release, her voice a whip crack, "Come, now."
