Chiaki Kamio, a 37-year-old housewife from Chiba Prefecture. Juggling her daily routine as a mother of two, a part-time library worker, and fulfilling her responsibilities at home, she maintains a strong curiosity and desire to explore new experiences. Inspired by online content and adult videos, she actively studies knowledge and techniques to enhance pleasure, constantly experimenting in her private life. However, her husband holds the mindset that "as long as I feel good, that's enough," creating a mismatch in sexual values between them. Amid this disconnect, Chiaki strongly desires to experience sex with a professional—where both partners genuinely bring each other pleasure. The highlight of this release is watching her latent sexual talent emerge and flourish.
