The middle-aged SM novelist Heisaki Teizō (played by Oosugi Ren) begins to feel creatively exhausted. In order to stimulate his creativity and complete a sensational work, he even asks his disciples Kawata (played by Murakami Jun) and Kyoko (played by Yamazaki Eri) to role-play in SM scenarios at his home, pushing the boundaries of sensuality. This method proves to be effective, as passages filled with warm, carnal desires flow from Heisaki's pen. However, while focusing on his writing, Heisaki neglects his beautiful and resentful wife Shizuko (played by Hoshi Haruko), who, feeling neglected, embarks on a secret affair with Kawata. When Heisaki accidentally discovers their illicit relationship, jealousy and anger entangle him, yet he simultaneously realizes that this is excellent material for his novel. The guilty Kawata, at Heisaki's request, details the entire process of his affair with Shizuko. This is an adaptation of the novel of the same name by erotic writer Dan Oniroku.
