F-cup gravure idol Yuu finally makes her AV debut! Her first sexual experience was at age 12, at the home of a second-year junior high school senior. Her memories from that time are hazy, overwhelmed by nervousness. Her erogenous zones are her clitoris and nipples, and her first performance is filled with anxiety and shyness. However, due to her masochistic nature, Yuu secretly desires to be dominated. Initially timid, she gradually awakens to her lustful true self, boldly grinding her hips and receiving cum on her cute face. Packed with tension and excitement, this video captures her raw, debut experience.
