Sitting in front of the desk, her face still red, the girl stared at the clothes on her lap, trying to peek at what he was writing in the prescription pad. The doctor placed the prescription form in front of her and explained calmly:

"You will need five antibiotic injections. They are necessary to complete the treatment and help you recover properly from the infection."

She hesitated for a moment at the doctor's latest request, which she tried to avoid with an uncertain voice: "Really... are they absolutely necessary? Couldn't I... take them in pill form?"

The doctor shook his head slightly, maintaining a steady, controlled smile. "The tablets are effective, of course, but the injections are more effective in the early stages. It's better this way, to be on the safe side."

Sofia remained silent, thinking that the last injection the doctor had given her wasn't so bad after all, and timidly agreed.

"All right... but... doctor, I... I don't know who to ask to give them to me," she admitted, her voice trembling slightly.

He smiled, his gaze fixed on her, and said calmly, "If you want, I can give you the first one." He knew Sofia had no alternative.

"But doctor, I'm going back to Livorno tonight... what am I going to do?"

The man had already thought of everything...

"Don't worry, I'll give you the contact details of a former colleague of mine, she's a very good nurse. Now go and lie down on the bed."

He watched Sofia as she got up and slowly walked back to the bed, which was now in horizontal mode.

She walked slowly, feeling awkward, her genitals still extremely sensitive, and having to expose her body to that man again embarrassed her tremendously.

She plucked up her courage, grabbed the elastic of her shorts, and pulled them down along with her panties, exposing her young bottom once again.

Trying to avoid the doctor's gaze, she lay down on the bed again, waiting for the man to return to take care of her with the air that caressed the skin of her buttocks.

Meanwhile, Dr. Moretti had already taken the vials of powder and liquid from the medicine cabinet and was about to remove the syringe from its packaging, glancing at Sofia from time to time.

She was lying on the bed with her bottom completely exposed.

There was a methodical calm in the doctor's movements, but behind his composure there was a subtle satisfaction: the pleasure of seeing her exposed again, fragile and forced to obey once more, even after reaching a pleasure she had never experienced before.

He would give her the injection shortly and knew that this latest invasive procedure would elicit several complaints from Sofia.

The girl glanced furtively at the doctor, who was just finishing filling the syringe with medicine.

He had used a 10ml syringe and, having only saline solution in the clinic, he had preferred to dilute the powder as much as possible in order to alleviate, albeit slightly, the burning sensation that the young patient would feel.

Sofia, in fact, turned pale at the sight of that huge syringe filled with yellowish liquid and, alarmed by its unusual size, asked why.

"Doctor, it's huge! Can't you use a smaller syringe?"

The man, convinced of what he was doing, tried to calm the young woman down just as he was about to pour the disinfectant onto a cotton ball.

"I understand your fear, Sofia, but I only used a larger syringe to better dilute the medicine in order to alleviate any discomfort as much as possible,"

said the man, knowing that the syringe had a much longer needle than the classic ones. It was needed to better penetrate the painful liquid into the patient's buttock.

Sofia watched him approach with that huge syringe in his hand. Her heart was beating faster and faster in her chest, partly because of her fear of pain, but mainly because of the feeling of total abandonment she felt towards the doctor.

It seemed inexplicable to her, but as soon as the man gently placed his hand on her leg, she felt a certain excitement between her thighs again.

The smell of disinfectant filled the air, a sign of what was about to happen.

The doctor placed the cotton ball soaked in pink liquid on the smooth skin of Sofia's buttocks and began an energetic massage of the upper quadrant of her buttocks.

He stared for a moment at the girl's soft bottom, as if wanting to imprint in his mind an image he would probably never see again.

Sofia felt the cold spread, leaving a damp sensation that contrasted with the warmth of her body. The smell now seemed more intense, as if it had penetrated her skin, and for a moment all her attention was focused on that precise spot. Instinctively, she held her breath and her muscles stiffened slightly.

Then the cold vanished for an instant, creating a brief void in which she could hear only the sound of the doctor behind her.

"Try to relax, take a deep breath."

he said as soon as he removed the cap from the needle.

He removed the last air bubbles and, once he had a firm grip on the syringe, he sank the tip into her buttock with a decisive gesture.

The cool skin offered a little resistance before letting the 5 cm inside.

The thickness of the cannula was much greater than in classic syringes and caused the poor girl's first protests.

"Ouch, ouch, it's too big!"

she cried.

But the doctor, holding a hand on her back as if to prevent sudden movements, began to press the plunger to inject the antibiotic.

She wasn't ready for that kind of injection. In fact, as soon as the liquid began to enter, Sofia immediately felt a strong sensation of internal pressure that quickly turned into pain. A sharp, growing pain that took her by surprise.

Her muscles began to stiffen, including her buttocks. She tried to resist by remaining silent and clutching the paper on the bed, but the pain was too deep; it felt as if her gluteal muscle had no more room for that liquid.

"Hhhhh... hhmm..."

Every millilitres that entered seemed to pull the muscle in every direction. Her breathing became short, her hands clenched the edges of the bed, and her heart pounded in her chest. She tried to hold back, but the tension suddenly exploded.

"PLEASE, STOP!!! I can't take it anymore...!"

"It hurts too much...!"

"Uuuuahhh... OUUCCHHH..."

Tears streamed down her face without her being able to stop them. Every muscle was tense, her body trembled slightly, and her voice broke as she tried to breathe slowly.

The doctor had expected this reaction; unfortunately, without lidocaine, the ceftriaxone was very painful. He tried to reassure Sofia by stopping the pressure on the plunger for a few seconds.

"I know it's painful, Sofia, but try to hold on, it won't be long now. Try to breathe."

With a trembling voice, the girl could only manage a timid OK.

The doctor returned to inject the last endless 3 ml of the drug, maintaining constant pressure. The poor patient was now crying uncontrollably, begging him to stop.

During these last moments of torture, Dr. Moretti thought about how the pain the girl was experiencing would be a mark for a few days, a memory she would carry with her.

The liquid finally ran out, and he tried to comfort her.

"It's over, it's over, Sofia, you did very well,"

he said as he pulled the large needle out of her young buttock.

While the doctor began massaging her buttock again to spread the liquid inside the muscle, the girl tried to regain control of her breathing, continuing to sob as if to release all the tension she had built up.

After a few moments of painful massage, during which Sofia struggled to relax her buttock, he removed the cotton wool and threw it away. He looked at her buttocks one last time and gently told her to get dressed.

She got off the bed, trying to cover herself as quickly as possible, still incredulous at what had happened that afternoon.

The man watched her get dressed and, once back at his desk, advised his young patient not to have any kind of sexual intercourse during the course of antibiotics and to avoid any contact.

With her eyes downcast and still wet with tears, she nodded shyly.

The doctor knew how much she wanted to touch herself again after this latest series of medical procedures.

Before saying goodbye, the doctor handed her the business card of the nurse in Livorno.

"Call her, she'll help you."

Sofia took it and thanked him shyly, still completely embarrassed.

With her bottom still sore, she left the doctor's office and returned to her tent.

As she walked among the pine trees of the campsite, her thoughts returned to what had happened on that bed, and even though she didn't want to and found it incredible, she continued to find it all extremely exciting.

It would be hard not to feel pleasure for the next four days, thinking back on what had happened with that doctor. But she wanted to follow the doctor's advice, at least to get rid of the discomfort that had brought her to him in the first place.

Four days and four painful injections.

A shiver ran down her spine. She didn't know if it was fear or excitement.

She picked up the business card.
