A child who was always pale and clear as if she were transparent, always in the corner, always with a troubled expression. Were you also thinking about sex? Madoka-chan, a true girl in a box, with a strict household and still has a curfew. The growth of her body, fantasies before sleep. In the fleeting moment between "girl and woman," you experienced your second sex life through an AV. No fabrication, a documentary that can only be seen now.
