Riko, known for her cool short hair, has never had a boyfriend before but is deeply curious about sex, making her first sexual experience in an adult video a rare and precious opportunity. Riko has never even undressed in front of a man until now, yet when asked, she surprisingly removes her clothes quickly. Her composed demeanor carries a mature air, but as foreplay begins, she suddenly grows quiet—clearly revealing her inexperience. Her innocent, restrained expressions while having her breasts sucked are pure and maidenly, and that purity only heightens her charm. During her first penetration scene, her visible pain evokes a sense of taboo, yet simultaneously intensifies arousal. The anticipation of delivering first-time pleasure to her untouched pussy leaves a powerful impression on both Riko and the viewer.
