Mother Makoto was a woman who could not be put away. Makoto, who ran away from her husband in a messy house without doing housework, lives with her three remaining sons. I don't mind at all even if my butt sticks out. It is not unreasonable for adolescent sons to lust for such a defenseless mother, but the relationship between parents and children gradually changes. And Makoto, who is weak against pushing, drowns in pleasure.
