I tried to be a good mother. But I couldn't. That's because my daughter's friend, Takuya, is just too cute... This is the story of a chaste mother who, having suppressed her sexual desires in order to raise her child, is violated and impregnated by an unethical boy. She realizes that she is a pervert, and the twisted pleasure she feels makes her abandon her role as a "mother" and immerse herself in the abnormal act of making a child.
