Miki, acclaimed for her exquisite doll-making and actively teaching at a cultural workshop, becomes deeply drawn to her student Reiko. One day, she invites Reiko to dinner and secretly administers a sleeping drug, rendering her unconscious. Reiko is stripped completely naked, her limbs tightly bound, as Miki meticulously caresses her body, delivering relentless pleasure through skilled cunnilingus. From this experience, Miki becomes obsessed with creating a beautiful, sentient doll—her very own living masterpiece. Their relationship evolves beyond mere artistic pursuit, transforming into something far more intense and transgressive, crossing into uncharted territory of desire, restraint, and somnophilia.
