"Lately, my wife has been distant..." Driven by this anxiety, a husband installs a hidden camera in his home. What it captures is his beloved wife, An Ogura, who refuses insertion with a "Not today" as her husband prepares for a business trip, and merely goes through the motions with oral sex. However, the moment the husband leaves for his trip, the screen reveals a cruel reality. She brings her lover into the house, clinging to him with a radiant smile he's never seen before. Drowning in intense caresses, she indulges in passionate intercourse she would never show her husband, reaching climax multiple times on her own. The lens captures every vivid detail of An Ogura's betrayal, soaked in the pleasure of sin. Here lies a record of infidelity too real and too cruel.
