My name is Ken Isshiki. The female who is now tied up and moaning lewdly is my wife Momoko. We've been married for 10 years, and even though I've been working hard and feel lonely, I thought my wife understood. At that moment, he is betrayed by his wife and subordinate, and he ends up witnessing Momoko's lewd appearance... When, where, and how many times... did he repeat his unfaithfulness? I want to hear every detail...but I don't want to know all about Momoko's shame, so I'm going to confess it here tonight.
