As our third wedding anniversary approaches, my wife Yuki says that after living so responsibly, she wants to try something special: posing nude. While I hesitate, my boss Dango learns about the idea and quickly arranges a photographer he knows. On the day of the shoot, I still cannot commit even after Yuki undresses. Dango offers to stand in as the husband, strips naked, and begins posing intimately with my wife. The nude session draws her into humiliation and an affair, captured in shocking footage.
