A genuine female masochist, Miss Akari, voluntarily visits rope master Chiba to endure intense BDSM torment. Carrying a deep passion for submission beneath her innocent expression, she eagerly anticipates each moment of punishment. A powerful nose hook pulls her nostrils sharply upward, forcing tears, while a ball gag restricts her to mouth breathing. Though her face shows distress, as a true M-girl, she appears to relish the unbearable pain. The relentless facial and nasal torture continues with four-way hooks, double nose spreaders, and skull clamps. Her bare pussy is exposed and spread open with fingers, revealing thick, virgin-like labia enveloped in slick mucous membranes. Handed a toy, she experiences the pleasure of public insertion. Into her unused anus, Chiba's thick finger plunges deeply, heralding the beginning of new sensations.
