I am Tooyama Ryouta, 32 years old. I live with my wife Mika, who is three years younger than me, and we have been married for about half a year. Recently, I started working part-time. The other day, out of curiosity, I peeked at my wife's smartphone and found a video of her with someone else's large penis. Holding this troubled feeling, one day when my wife was late coming home, I went to her workplace... and there she was, moaning with a man who seemed to be the store manager.
