At the age of 12, Olga had her first menstruation. Her older sister Nina reassured the panicked girl and told her that it was growing up.
A couple of months later, however, problems arose. Olga began to eat a lot, her body demanded more and more meat. The child's body was changing rapidly. Olga outgrew Nina in a year. Her older sister was proud of her height of 175 cm, but her younger sister became taller.
Olga attracted unwanted attention of her peers and older guys because of her height. At the age of 14 it was decided to transfer Olga to home schooling.
At this point 16-year-old Olga and 25-year-old Nina are sitting outside the office of a doctor who has experienced similar abnormal height among teenagers. Nina believes that the doctor will be able to answer the girls' questions and make recommendations on how to stop Olga's growth.
