She's only had sex with one person! Rin, a pure and innocent girl who is super innocent both in appearance and personality, makes her exclusive debut! She's embarrassed to look at a penis in a bright place, and in front of other people, but she's so curious that she can't stop grinning! Her white, beautifully shaped, sensitive breasts are still underdeveloped, but when she masturbates and has a threesome for the first time in her life, she seems to be blushing to hide her embarrassment, but she feels so good that she climaxes many times! She's actually a very naughty 19-year-old girl!
