The doctor looked at her for a moment, almost smugly, but decided he couldn't leave her in that state for long. He would give her something to relieve her discomfort, thinking about what the young patient would still have to endure.

"Now I'm going to give you a painkiller," he said in a calm but firm tone.

He said nothing more, preferring to explain each step as he went along so as not to increase her anxiety.

He got up from the stool and went over to the metal cabinet in the doctor's office. He opened the upper cabinet door and rummaged inside for a few moments, until he took out a blister pack of painkiller suppositories. Sofia watched him closely, without understanding what it was, as the doctor returned to the bedside.

Only when he was close and began to put on a new pair of gloves did the situation become clear to her. He had taken a pack of paracetamol suppositories.

A suppository? A shiver ran down her spine, her cheeks flushed, she was incredulous, almost intimidated, yet she could not find the strength to object, except verbally.

"No, please, not a suppository... Is it really necessary, doctor?" she asked, her voice slightly cracked.

"Trust me, Sofia, it's the quickest and most effective way to make you feel better," he replied without hesitation.

Tied to the bed, helpless, she realized that she would be penetrated in the butt again, just like a few days earlier. The image and sensation of that rectal exam came back to her mind incredibly vividly. So vivid that it made her extremely aroused again.

With his hands protected by the new pair of sterile gloves, the doctor took the tube of lubricant from the trolley next to the bed.

He paused for a moment. He looked at Sofia, lying there in such an exposed position. His gaze lingered on her genitals, still obscenely open from the speculum, and that large catheter still inside her urethra; they were shiny with vaginal fluids and the gel used earlier. Probably no further lubrication would be needed to insert the suppository. But it was too tempting an opportunity.

So, he applied a thin line of gel to his finger and, once seated on the stool again, spread her buttocks slightly, completely exposing the pink orifice and beginning a gentle external massage.

Sofia closed her eyes and gasped slightly, enjoying the sensation, knowing that what was about to happen in a few seconds would drive her crazy.

The doctor, in fact, wasted no time in taking the previously discarded suppository and, after guiding it to the young opening, began to insert it slowly.

The generous 3 cm of medicine entered the girl's bottom easily, but to make sure it penetrated all the way, the man accompanied the suppository by sadistically inserting his middle finger to its full length into the young opening.

Sofia jumped and tightened her muscles slightly, more out of embarrassment than pain. However, that big finger, now inside her, generated those incredible sensations she had experienced in the previous days. Keeping her eyes closed, she let herself be overwhelmed by the penetration, even imagining herself being possessed by that man! A small moan escaped her, more from pleasure at the thought than from pain.

"That's it... good girl, breathe slowly," murmured the doctor, completing the insertion.

He waited a few second and then he and removed his finger to prepare the second paracetamol suppository. The procedure was repeated calmly, with Sofia increasingly in the throes of submission. However, once inserted, the doctor left his finger in her bottom for a few moments, moving it slightly in a very compromising manner.

The young patient was now completely dominated. She would have liked to be penetrated like this until she reached orgasm, but the doctor, despite himself, had other plans.

Almost sadistically, he removed his finger, stood up, and took off his gloves.

"Perfect, you'll feel the effect soon and you'll be better."

Sofia remained motionless on the bed, still breathing heavily from the pleasure she had almost experienced, but the weight of humiliation was still alive: she would never have imagined undergoing such intimate treatment, unable to resist, under the imperturbable gaze of that man who continued to treat her with such disarming confidence.

The doctor, after reconnecting the syringe to the catheter still inserted in Sofia's vagina, warned her in a calm tone:

"Now I'm going to remove the catheter. You may feel a burning sensation for a few seconds, try to relax."

She nodded slightly. She felt the man's gloved fingers gently brush the inside of her thighs to stabilize the tube. A slight discomfort ran through her as the internal balloon was deflated, followed by a sudden burning sensation as the catheter was slid out of her urethra.

"Ooh, slowly, slowly," Sofia moaned as the 10 cm of latex tube was removed.

The doctor, unconcerned by her complaints, placed the catheter in a sterile container, removed his gloves with an expert gesture, and threw them in the appropriate bin.

"Okay, that's it. Breathe. Now let's continue calmly."
