At just five feet tall, Sue is a university student who looks very young for her age. Frustrated by her lack of height, she wishes she could disappear for a couple of years while she grows a bit more. She lives alone in a rented flat close to college, and one day bumps into her sociology lecturer, Julia Roberts. This leads to Sue babysitting Julia's children on a regular basis, and over time she becomes very fond of the family, eventually moving into their spare room and being treated as a member of the family. She even wears the clothes left by Julia's 14-year-old niece, and enjoys doing the same things as other young teens: ice skating, trips to the park and cinema. Julia's husband, John, works overseas in South Africa, and when the opportunity arises, the family, including Sue, spend a two-week holiday with John in a township close to his firm's engineering plant. They later decide to live there for two years, and during that time, Sue will attend school, being placed in a class of 15-year-old students. It seems she has got her wish...

This domestic story has an element of age play as it focuses on the consensual age regression of twenty year old Sue, who easily passes for and lives the life of a fifteen-year-old school girl. It relates how well she adapts to her new life and comes to regard Julia as her mother. Julia is a little old fashioned and doesn't hesitate to give Sue a spanking when it is deserved... it is all part of growing up.
