Today is the day of the yearly medical exam. The school nurse is sick that day and the burly black Janitor covers for her. Annoyed, 13 year old NAME_1 is standing naked next to a measuring tape, covering her small breasts and vagina with her arms: "Is it really necessary for me to be naked to measure my height? And to take photos?" "Mhm, school policy", the janitor replies with a hint of a smile, "Arms down at your sides, Miss".
Flesh out and embelish the story.
