A young orphan girl, Sayo, is taken in by the master of a luxurious Western-style mansion and grows into a beautiful woman. The master, consumed by possessive desire, brutally torments her in the basement, indulging in pleasure. Her skin is licked, her hair drenched in saliva, and her body overflows with delight. A long, entwined tongue crawls across her face, reaching her ears, nose, and eyes, and her body moves vigorously. The body of Sayo is a collection of a perverted man's desires, expressing every aspect of them.
