Former gravure model Miku Horikita makes her bondage debut. Ropes bite tightly into her adult sailor-uniform role-play outfit and emphasize her full breasts. Suspended in midair, she trembles and cums repeatedly under a powerful vibrator; tied with her hands behind her back, she is penetrated while helpless and feels more pleasure despite the humiliation. Crotch ropes, a wooden horse and clitoral torment gradually turn the seemingly innocent beauty into an obedient bondage sex slave.
