Hinano, troubled by her husband's inability to let go of his single lifestyle even after marriage, decides to confront and scold him. But he keeps justifying his endless womanizing. Provoked, she challenges him: "Then show me your so-called impressive big cock right here, right now!" Surprised by her boldness, he reveals himself—and before her stands a monstrously huge cock beyond imagination. The sight ignites her long-suppressed desires, and Hinano's body responds intensely, gradually becoming obsessed with his massive shaft.
