Obey and get undressed

"Yes s-sir" you stammer, and retreat to the bench to get undressed. You unbutton your blouse and skirt, carefully folding them and placing them neatly in a small wooden box. You hesitate a bit, and then set on the bench to remove your shoes and socks, adding them to the box of clothing, and revealing two pair of cute feet with small, well-manicured toes.
Then, red faced, you stand and tug your bloomers down, and finally pull your chemise over your head, concentrating on your hands as you fold the last of your clothing neatly and tuck it under the clothing already in the box. You come out and stand before me, hands covering your genitals.

Hands on hips, I sternly pronounced, “Very well, since you choose cooperation, we shall take the less painful path.”

", I want you to take a seat on the end of the other examining table.” I rang a bell, and my secretary joined us. “I am so glad that you decided to cooperate,” she said, “it frets me terribly when the Headmaster is required to deal with the horrible behavior some of the children display!”
It occurred to me that I had not made introductions earlier. “Children, this is Mrs. La Place; she is a trained nurse, my personal assistant, and confidential secretary. Her husband, may he rest in peace, was a victim of Tuberculosis, and since his passing she has devoted herself to my wellbeing both body and soul for these last twelve years. She will be assisting me as needed, and recording the results of the examination. Let us begin. Please step up onto this scale and state your full name for our records.”

"{FISRT_NAME} Leigh Doe. "

“State your date of birth, and current age.”

“March 21, 1937, Sir, and I am 16 years old.”

Height and weight?

“Why do you ask; you are going to weigh and measure me anyway?”

Surprised by this flash of boldness, since so far you have been quite reticent, I snapped out, “It matters primarily because I say it matters.” I paused, feeling a bit indulgent, and continued. “Collecting your perceptions and comparing them with my observations sometimes proves useful.”

You blink several times as you consider my response. You are clearly very intelligent, more so than your age would indicate, but for all of your intelligence you are completely oblivious to the social gaffe you have committed. “I am just over five feet tall, sir, I’m unsure of exactly how much, the last time I was measured I was exactly five feet one inch, but I’m sure I have grown. I used the freight scales at the railroad station, I weighed 115 pounds.”
