My wife and I run a small house cleaning business in a certain city in the northern Kanto region. We have had a regular client called Mr. Nagasaki since last year. He has a son who is over 30 years old, has no permanent job, and spends all his time playing games in a messy room. One day, when I was cleaning up his room, I found a video on his PC that looked like he was taking a secret video of my wife's butt while she was cleaning.
