[240TOKYO-479] Yuko

Performing as sisters! First of all, "Yuko" older sister with a cool beauty image. She is a cheerful and easy-to-talk woman and is currently a piano teacher. She grew up in a strict and cramped family environment where both parents were teachers in her old house, and she had a normal sex life with four experienced people in her hometown, but she moved to Tokyo from Nagano to enter a music college in Tokyo, lived alone and touched a sense of liberation that she didn't have to worry about the eyes of others, speared with a man she met at a joint party, and is now a nasty and uninhibited woman. - Please see the foolery of my sister who is disturbed and spree without knowing that her sister knows about the appearance. - In the second half, she exposes her nasty nature in CA costumes.
