The development of the genitals of multiple girls are shown in closeup. The hairless vulva of a pre pubescent girl is shown followed by the genitals of older girls, aged 12-18. Each consecutive shot shows the development of the of the genitals, with more pubic hair and larger labia than the previous, up to full adult development. Shots are explicit and closeup but educational in nature.
