Shiho had a daily habit of indulging in her own lush, soft breasts and admiring her perfectly balanced, beautiful figure. One day, her neighbor's teenage boy, Shinji, suddenly visited and entered her room, where he gently massaged her large breasts and passionately pleasured her body. Overwhelmed by the intense stimulation, she experienced wave after wave of soaring pleasure, loudly expressing her overwhelming ecstasy. This moment became a uniquely special experience for her.
