[Ishimiso] Marunomi to Koumon [Kuraudo]

An adventurous high‑school girl ventures into a deserted seaside cave, dismissing ghost rumors until a massive, slick tail erupts and pins her against the stone, trapping her in a forced, anal bondage. She struggles as the creature slides into her mouth and rear, leaving her immobilized and melting into a single, suffused form while she whispers that they are blending together. The tension builds toward an unresolved climax where the girl’s fate hangs in the balance of this surreal, erotic encounter.
