I have a son named Masaki. He was quiet and cute when he was a child, but after my divorce he suddenly went wild... Now he doesn't listen to me at all. One day, I happened to see Masaki masturbating. When he noticed my gaze, he became enraged and started saying obscene things to me, and eventually even touched me... From that day on, our relationship as a parent and child developed into something forbidden that was different from that of an ordinary family.
