Charlotte Brown tied her long brown hair back into a ponytail and applied her lip gloss, before sighing as she perused her reflection in the body length bedroom mirror. Despite being eighteen years of age and having developed a pert, curvy pair of boobs and butt, she was still forced to wear the same childish school uniform as an eighteen year old sixth former that she had worn for the previous 13 years at the school. Her school, Mary Bastable Preparatory School for Girls, was a bit of an enigma to those not within the elite circle of people who either attended or worked in it. A private school with a strict behavior policy, the school had recently allowed it's eighteen year old girl pupils to wear makeup and simple jewelry, but the large amount of it's antiquated uniform had been unchanged for over fifty years. Even the eighteen year old sixth form girls who were legally adults were bound by the strict uniform policy, and with it the potential to pickup hour long detentions for any noncompliance. Much to the girls' chagrin this meant strictly no trousers allowed, school standard black shorts and t-shirts only in Sport with only the navy blue and green school branded pleated skirts allowed at all other times. Although in practice this part was not enforced, the strict uniform policy sent to parents also mandated that only white underwear could be worn under their skirts, something Charlotte Brown's mother had embarrassingly taken at face value, insisting even at eighteen that her daughter should follow the school rules to the letter, packing her off to school in white bikini knickers and skirt, dismissing her pleas to be able to put on a pair of cycle shorts on underneath. Today was Charlotte's penultimate week at sixth form before heading off to study medicine at the town's University, something she could not wait to start as she would finally be able to be out from under the watchful eye of her strict, overbearing parents.

"When you are at University you may wear what you want. At school you are to follow the rules so we get you a good academic reference. You understand me, lady?" her mother had firmly insisted when dropping her off at the school gates.

The day had started with Charlotte and the other sixth form girls attending morning assembly, which mainly discussed the written end of term assessments for various subjects the girls would be undertaking. Their had of sixth form Miss Harrington was coming to the end of her speech about the day's timetable.

"Please stand" said Miss Harrington as the assembly came to an end. "The fifteen girls who are booked in to see the school nurse today for your physical exams for University are to stay behind, the rest of you are dismissed", she said.

The majority of the sixth form girls silently exited the hall in a line, leaving Charlotte and fourteen other girls stood to attention in the hall. They had been advised the week prior they would be seeing the school nurse on this day for a physical examination in relation to their University entry. Charlotte and the other fourteen girls this affected had been instructed to bring a copy of their medical records along with the white school t-shirt they wore for sports. Ms. Wilson the school nurse, a sour faced plump middle aged woman entered the hall as the last of the sixth formers exited, joining Miss. Harrington on the stage. Ms. Wilson greeted Miss Harrington. Miss. Harrington instructed the girls to put away several of the benches, leaving two of them laid side by side in front of the stage before being instructed as Ms. Wilson placed brown paper over the glass on the door windows, blocking the view inside the hall, doing the same with the doors at the end of the corridor containing the nurse's office.

"Is that everything we need?" Ms. Harrington asked Ms. Wilson the school nurse who was stood watching.

"Perfect, the corridor up to the sports block is closed to the rest of the school so should be fine, do carry on Ms. Harrington" replied Ms. Wilson.

"Right girls, come here!" shouted Miss Harrington.

Charlotte and the other girls stood in a circle in the middle of the hall chatting loudly.

"Quiet!!" shouted Miss. Harrington.

The girls complied, arms at their sides as they stood to attention for Miss. Harrington and Ms. Wilson as per the school rules as both members of staff walked back onto the stage Miss. Harrington was keen to keep the lead up to the examinations as formal as possible to ensure good behavior from the girls.

"Good morning girls!", said Miss. Harrington.

"Good morning Miss. Harrington. Good morning everybody." said the girls unenthusiastically, reciting the greeting they had to use in every meeting or assembly with the school staff.

"Please be seated" said Miss Harrington. The girls sat down on one of the benches as ordered.

"As we all know, you will all soon be leaving Mary Bastable for University. Ms. Wilson will now address you with regards to the examinations you will he having today in connection with this. Ms. Wilson?" said Miss Harrington, indicating for the school nurse to proceed.

"Thank you Miss Harrington. Now girls, in the letter you were sent last week you will have been asked to bring your sports t-shirts in today. You are to get changed into this here in the hall. Everything else except your underwear needs to come off. You will each be given a plastic container to provide a urine sample. Go over to the changing room in the sports block. Once you have given your sample, you will need to have a quick shower with the antibacterial shower gel we have left out for you in the locker room. I will be back to get you in ten minutes. Any questions?" asked the nurse.

"Who loves you?" shouted Charlotte.

The other girls burst out laughing at this, making Ms. Wilson red with rage.

"Don't be so childish, girl!" rebuked Ms. Wilson.

Charlotte blushed, looking down at her feet.

"Now then girls, you have your instructions. Do we have any questions?" asked Miss. Harrington, to be met with silence.

"Good. Please stand!" said Miss Harrington.

The girls stood to attention as Miss Harrington and Ms. Wilson walked off the stage, Ms. Wilson handing out specimen containers to each of the girls, before exiting the hall along with Miss. Harrington.
