The Hatano family was living a peaceful and happy life when disaster suddenly struck. The god of death has taken the life of the husband, now only the mother and daughter have to try to rely on each other. Although the son is in high school, he is very stupid and stupid, and the two words "sex" always appear in his mind. Although he saw the neighbor flirting with his mother, and even intended to rape her, he didn't know what to do but stand and peek at the eyelash artist who was singing non-stop. And yet, sex also dominates his person and personality. After many times deliberately peeking at his mother and masturbating, until today he couldn't stand his own cravings. Even though it was his biological mother, he still defied all his determination to rape her in order to satisfy his curiosity and desire for a long time. What an unfilial child.
