Mumu makes her second appearance in "Adult Vinyl Book" from Vinyl Bookstore. Known as the cute flesh angel, her sensitive body is her charm—she lets out adorable moans from just light feather touches, making her prominent clitoris stand erect. She performs blowjob on her own clitoris, and even while being tormented with toys, she maintains a purely girlish expression. The surprising detail of her having a visible clitoris further enhances her allure. She also deeply enjoys intense deep-throat sessions, and with anal and cock penetration, she displays classic ahegao expressions, craving ever deeper thrusts—an absolutely angelic presence.
