A 20-year-old returnee girl makes her AV debut. Possessing a pure heart—having never even seen her family's penis—she's portrayed as so shy during her first shoot that she nearly runs away from the set. During her first sex scene, she's overwhelmed by the new sensations, experiencing both pain and pleasure, even shedding tears. By the second round, techniques that bring out her body's softness and sensitivity are applied, and despite it being her first time, she's shown immersed in intense pleasure.
