Elisa glanced at the envelope that was slid under her door – University Health Checklist. She picked it up and nervously tore it open, wondering what even was a health checklist?!

The letter began

“Dear Elisa,

In reviewing your health records it has come to our attention that the below vaccinations are now out of date and need to be renewed. As you know it is university policy that all students must maintain compliance with required vaccinations. The doses that you are required to receive are:

- Meningitis vaccination

- Tetanus booster

- Hepatitis B

We have scheduled you into the clinic tomorrow at 11am to rectify your missing doses.”

Elisa felt weak and light headed. Her knees buckled and she involuntarily fell back onto her bed. She held the letter in her trembling hands and stared at the missing vaccinations. That means she would have to receive 3 in one go… 3 needles, 3 pokes, 3 plungers being pressed into her.

She could hear her heart beating in her ears. She laid on the bed and took some deep breaths. Her mind drifted to the last injection she had received. As the thought crossed her mind she felt blood rush to her groin. She remembered the whole dynamic of being under dominance of the doctor actually turned her on. She relished being fully submissive and obedient and knowing that in that power dynamic, nothing she could say would shift the inevitable actions that would take place.

Her hands slid to unbutton her jeans and her fingers flirted with the lace on her underwear. She made a conscious decision to stifle the urge; deciding to postpone it till tomorrow morning before her appointment. An orgasmic stress relief could only help calm her nerves before she headed to the clinic.

Elisa woke up a few minutes before her alarm rang at 9am. As the sleep faded into wakefulness the reality hit her: in a couple of hours she would be getting poked. The idea struck a kind of fearful anticipation for what was to come. She started to imagine the doctor instructing her to lay down or to sit, the strong smell of the antiseptic, the *pop* sound of the needle uncapping… She was already wet.

She ran her hands underneath her panties to connect with the source of her desire. Her lips were gorged and her clitoris throbbed as she nestled her fingers around it. She imagined being completely submissive and the doctor giving her orders. Her mind raced with thoughts of her obeying the doctor but hiding the pain and the fear – her only remaining power in that dynamic.

Elisa coaxed forward her orgasm until it completely overtook her body – wave upon wave washing over her; granting her the release she so desperately desired. She collected herself and pulled her blonde hair into a bun before heading to the bathroom to get ready.

She had picked her clothes for the occasion – a white tennis skirt, a pink top, her green laced La Perla panties and a pair of sneakers. She was determined to take control of whatever factors remained in her hands at that point in time.

She entered the clinic and made her way to the front desk where she announced herself. The nurse told her to take a seat. The waiting room was empty. She picked up an old fashion magazine and nervously flicked through the pages until she heard her name being called. It was the nurse.

“You can make your way to exam room 3 Elisa, the doctor will be with you shortly”

Elisa nervously stood up and walked through the doorway into a corridor filled with exam rooms. She reluctantly opened the door to exam room 3 and was greeted with a blue medical exam table, a neat counter with tongue depressors, cotton, a variety of antiseptics and a yellow sharps box. She glanced inside and saw a dozen or so used syringes – she couldn’t help but wonder who were the students that those needles had poked… She knew by the time her appointment was over, the sharps box would contain 3 more syringes and needles.

She sat on the exam table and continued scanning the counter. No sign of needles or syringes. Her curiosity got the best of her and she gently pulled open the top drawer. There they were: blue capped needles stacked in groups of 10 in a white and blue box labelled “BD Microlance 23G x 1” Nr. 16”. She took a sleeve of 10 syringes and needles to have a closer look – that’s when she heard the door handle begin to move.

She just had enough time to turn around and hide the items in her handbag before the door fully opened and the man in the white coat entered the room.

This doctor was young and in shape: he had a neatly trimmed haircut which accentuated his thick black hair, and he sported hints of a 5 o’clock shadow. She noticed his broad shoulders as he smiled at her and shook her hand, introducing himself.

“Hi Elisa, I’m doctor Oscarty but you can call me Victor”

She shook his hand and responded in kind.

He took a seat on the small stool, wheeled it close to the exam table and flipped open her chart.

“Just catching up on some shots then correct?”

Elisa nodded, her voice nowhere to be found.

“No problem I believe the nurse has them ready: we should be done in no time”

The doctor buzzed the intercom and instructed the nurse to bring the shots that were set aside for Elisa.

In less than a minute the nurse knocked on the door and lay the stainless steel tray on the countertop. Elisa could see 3 loaded syringes: 2 of them with blue capped needles and one with an orange cap. Her heart began to race.

The doctor headed to the counter and began washing his hands with the antiseptic soap. He looked over at Elisa as he was drying his hands and said:

“You look pale… do needles make you nervous?”

“Yes…” Elisa said softly… Her eyes began to well up as a mix of emotions arose inside her.

The doctor consoled her and assured her everything would be quick and painless. He told Elisa he would administer them into her butt cheeks so she wouldn’t have to worry about fainting or making sudden movements.

Elisa was filled with nervous anticipation but now that he mentioned this piece of information she immediately felt her lips flush with moisture. Her cheeks were red as she tried to hide her arousal.

The doctor instructed her to pull down her skirt and lay face down on the blue exam table.

Elisa duly complied. Her hands slid her white tennis skirt below her butt cheeks revealing the green lingerie she had chosen for the occasion. She swung both legs over the exam table and presented her ass for the pokes. She hid her head in between her arms.

She smelled the strong scent of antiseptic in the air and heard the doctor picking up one of the syringes. Her clitoris was throbbing from anticipation and she could feel her wetness soak the fabric of her panties.

The doctor swabbed her left cheek and she heard the unmistakable pop of the needle uncapping. The doctor instructed her to count to 3 but as she began counting she felt the pierce of the needle against her skin – a momentary spike of pain which quickly subsided as she felt the needle glide inside her and into her muscle.

The doctor pressed the plunger quickly – which she was not prepared for. The vaccination burned as it entered and the speed at which he had delivered it made her cry out “owwww”.

The doctor withdrew the needle and syringe and apologized to her by saying

“I know this one hurts the most and you are done with it”

Elisa felt the soreness of the injection site and turned her head just in time to see the doctor standing above her other cheek with the second syringe. She had made up her mind to watch: hoping that it would stifle her arousal and contain her nervous excitement enough for the doctor not to notice.

“Please go slower if you can” she said quietly

The doctor glanced at her and shot a smile: “of course no worries Elisa”

He swabbed her cheek and unsheathed the needle. He looked at her and asked if she was ready. She nodded.

True to his word the doctor positioned the needle above her skin and slowly proceeded to poke her with it. She saw her skin dimple and then absorb the entire needle into it as the blue cap was the only visible part remaining. This insertion hurt more and Elisa grimaced as it happened.

The doctor pushed the plunger slower than the last shot but the burning sensation still resurfaced.

Elisa closed her eyes and gritted her teeth. After a few seconds the doctor announced that was done.

Elisa breathed a sigh of relief… one more to go. When suddenly a mad idea crossed her mind.

“Doctor, I have a question… kind of an unusual question…”

“Go ahead!” he replied.

“Well… It sounds crazy but I will ask anyway… could you show me how to give myself an injection?”

The doctor was somewhat taken aback but quickly recomposed himself.

Elisa continued “well you see, I always make it a point to confront my fears head on and in the past it had always helped me overcome them…”

The doctor thought about it for a second…

“sure, if it helps you then I guess why not… Stand up then and lean against the exam table with your butt out”

Elisa complied.

The doctor spent the next 5 minutes explaining the mechanics of delivering the shot and piercing the needle perpendicular to the skin. He told Elisa he would be keeping a close eye and that if she changed her mind she could do so at any time.

Then it was time.

The doctor handed Elisa the syringe and gently uncapped it. He swabbed her cheek with antiseptic and guided her hand to a suitable spot.

“Whenever you’re ready…”

Elisa tentatively positioned the sharp needle against her skin, pushing gently but to no avail. She was too fearful to poke it any harder. She watched as her skin dimpled against the needle and failed to give way.

“You’re gonna have to use more pressure” the doctor instructed

She moved the needle faster this time and her skin submitted to the piercing gesture: half the needle was inside her now.

She gently pressed the other half in and started pushing the plunger. It immediately started to burn.

Elisa stopped. The doctor reassured her and told her he would take over. He told her to place her hand on the exam table and face forward.

Just as she did he quickly depressed the plunger and shot the vaccine into her muscle.

It hurt a lot and she subconsciously moved herself in an attempt to get away from the pain.

The doctor withdrew the needle and swabbed the injection site, placing a small plaster over the puncture wound.

Elisa massaged her cheek attempting to soothe the stinging…

The doctor smiled and told her “it would just have hurt more if I did it slowly”

He placed the syringe on the counter before gathering the swabs and tossing everything into the sharps container.

Elisa pulled up her skirt and inevitably her hands drifted to her ass cheeks which were now experiencing a dull pulsing of pain.

“Thank you doctor” she uttered as she grabbed her handbag and made her way outside. She opened it to present the nurse at the front desk with her student ID only to be met with the implements she had accidentally helped herself to earlier…
