START-374 A state of convulsions and trance! A documentary of the development of a back-arching climax! [Sudden transformation, collapse, awakening] A highly sensitive uterus that goes too far SPECIAL Hibiki Natsume

Three experiments and sex that blow away reason into an unknown world and immerse oneself in sex. Her true nature that we never knew appears. Hypnosis increases concentration, lustful herbs increase sensitivity, and in a state of sweating and sharpening, a man and a woman clash with each other's burning hearts. The climax is an overwhelming, extraordinary non-stop FUCK. The ending is beyond imagination, devoured like a beast.
