An abnormal lesbian work featuring twisted play where tongues and fingers aggressively twist into a woman's holes, presented in Morikawa-style VR. The protagonist, Makina, is a female student with a masochistic nature who has enjoyed being bullied by women since childhood. She is currently favored by her health teacher, Hana Kano, who forcefully dominates her anus in the infirmary after school. Kano's snake-like tongue relentlessly torments Makina's back door. Though Makina initially shows resistance, she gradually awakens to the pleasure, her expressions shifting from discomfort to arousal. Her conflicted state—torn between repulsion and ecstasy—forms the core appeal of this title.
