Nanami and I have been together for 3 years. Nanami is beautiful, kind, has a nice figure, and is honestly quite popular. But Nanami accepted my proposal, even though I am not very good at it. I couldn't be happier. ...I was happy... and then! Of all people, with him! I never thought it would turn out like that... When does cheating begin? I often hear such stories, but although it varies from person to person, I thought it was the same thing. A woman's mouth tells a lie! A cuckold story that starts with the mouth.
