I'm Ryo Tono, 32 years old. I've been working part-time for about half a year now, living with my wife Miho, who is three years younger than me. The other day, I happened to look at my wife's smartphone and found a video of her sucking someone else's big dick. One day, I was feeling uneasy, but my wife was late coming home, so I went to her workplace and found her moaning on the big dick of a man who was probably the manager.
