Shall we begin? (Patreon)

Twilight sat on the stool in the school infirmary and slowly swung he  lower legs back and forth. She always felt uneasy being here even if it  was for a scheduled visit. Behind her the door to the head nurse office  opened. The young mare turned started to say hello Fit n' Hardy the  school nurse when the words died on her lips.

    Instead of the  usual slightly rotund earth pony who ran the infirmary Twilight Sparkle  watched as her lifelong mentor and Co-Ruler of Equestria Princess  Celestia came walking over to her in an outfit like she'd never seen Fit  n' Hardy wear. Come around Celestia stopped in front of the unicorn.  Then with a smile on her face she addressed her pupil.

    "Hello Twilight! Thank you for coming today. How are we feeling today?"

     The violet unicorn made slight gurgling noise, then after a couple  seconds she spoke. "Your Highness. What are you doing here?" 

     Celestia smiled. "Well, Fit n' Hardy is unfortunately under the  weather. Food poisoning or something. And all of her assistants are off  at a medical conference today. Since her planned schedule was very light  today I've decided to sub in for her today!"

    Twilight nodded her head. "Okay. I don't mean to be disrespectful your highness but are you qualified to perform this job?"

    Celestia giggled. "Oh Twilight! When you've lived a thousand years you become qualified in many, many things."

    "Um, okay, but your Highness why are you wearing that outfit? It's, uh, um, not, well, standard issue."

     Celestia looked down at it and sighed. "Yes it is not standard  regulation. But imagine my frustration when I discovered that they had  no standard uniforms in my size! However I felt I should wear something  that was appropriately themed for the role I am fulfilling today. So I  improvised. This is a costume I wore to a Nightmare Nights ball a few  years, and it still fits!"

    Twilight's brain stripped a couple  of gears as it pondered the concept of her Highness wearing this at a  ball. After a few seconds she succeeded in reengaging the clutch to her  brain and coherent thoughts started forming again in her brain.

     Ignoring Twilight dumbstruck look on her face, Celestia reviewed the  paperwork on her clipboard. "Now apparently you are here for your annual  physical. Please follow me back to the examination room. There I'll  have you undress and we can begin."

    The young mare made a sound like somepony stepping on a small rodent.

    Next in my series of anthro nurse ponies so I decided to get one princesses done right away. More to come.
