My name is Ken Isshiki. The woman who is tied up and moaning lewdly is his wife Momoko. We've been married for 10 years, and even though I worked hard and felt lonely, I thought my wife understood. Just then, he is betrayed by his girlfriend's wife and her subordinate, and ends up witnessing Momoko's lewd behavior... When, where, and how many times... was she unfaithful? 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.
