"If you don't want this photo to be spread around, do as I say." One day, a boy who Reiko thought was her son's friend suddenly turned on her. Reiko was grateful that the boy had become a Kokoro to her shy son, and never dreamed that his true desire was for her body, and she opened up to the boy who frequently came to play. However, after secretly taking photos of Reiko masturbating, the boy's attitude suddenly changed. Reiko was powerless to deal with the threats of the boy, who was now a fully grown man with only his cunning and penis remaining.
