Publisher's editor Mai Kuroki visits an author to collect his overdue manuscript and ends up waiting in his old book-lined study. Aroused by the room, she begins masturbating and is caught by the blocked writer, who decides she is perfect inspiration for his unfinished erotic novel. He slowly undresses and licks her, buries his face between her legs, fondles her full breasts, shares 69, and adds a vibrator until she completely lets go. He then penetrates her in multiple positions, turning their private session into material for his story. He finishes in her mouth, and his masterpiece is finally complete.
