My aunt, Toshiyo, who regularly takes care of my late sister's family. While taking care of her, she eventually has a relationship with her sister's husband, Naoya. Her nephew, Noboru, who was secretly in love with her, learned the truth and felt intense anger and frustration. Unable to suppress her urge towards Toshiyo, he forcibly poked her butthole, saying, "If the hole in front is my father's, the hole in the back is mine!" Toshiyo, who was swept away by his too strong feelings, could not consult anyone and continued to feel the pain of her anal quietly.
