The new label "Youth", in which overwhelmingly transparent beautiful girls debut, has started. Nozomi Nishino, who is 150 cm tall and has a slender figure, is a quiet 18-year-old raised in a girls' school. She is not satisfied with the masturbation she learned after her first experience, and has a desire to be forcibly committed. The girl, who is shaken by curiosity and anxiety, grows up a little while writhing in the first pleasure.
