One day I accidentally saw a young girl in the room opposite mine. From this side window I can see the entire room on that side. There used to be an uncle who lived in that room so I didn't pay attention, but since this young girl moved in, I've always been peeping into her life. After a while, I learned a few things. She is Yume, a university student from the countryside. She also has a boyfriend from school. They kept making love to each other and of course I witnessed it all. Yume seems to be a masochist, she agrees to let her boyfriend do everything he wants. I'm clearly better than him, why does he get to fuck such a beautiful girl and not me?! So I recorded the scene of the two of them fucking each other and used it to threaten Yume, forcing her to do as I said, obediently be my woman and serve my sexual needs...
