EP.110 Urethral Training
Urethral Training Room.
Like other spaces, this small room, about 5 pyeong in size, was equipped with various tools for training.
On the shelves attached to the walls were urethral beads designed to effectively damage the urethra.
There were beads as thin as those a beginner might use, and others so thick it was questionable whether they could be inserted.
There were 20 different types of urethral beads, varying in size and shape.
If Heo Seong-ah's physical condition was good, she would use all 20 of these beads throughout the day.
"B62, please enter and sit down. Understand?"
"Yes, sir... Huh..."
Despite successfully removing the anal plug, the pleasant climax she was supposed to receive as a reward was nowhere to be found. Instead, she faced the urethral modification she had dreaded.
Her despair was palpable.
"Nngh..."
She wanted to run away.
She wanted to burst out of the room, rip off the suit stuck to her body, and crudely masturbate.
But with her vision obscured and her sense of direction lost, she could do nothing.
"Get up quickly and sit on the chair. Proceed."
"Yes..."
Guided by the manager's hand, she reached the center of the room.
As she walked, her head bumped into something, stopping her.
Feeling her way, she realized there was a chair right in front of her and sat down on what seemed like a saddle.
"Huh?"
It wasn't a chair; it had no backrest.
As she wondered if this was correct, she reached behind her and found a soft leather seat stretching out in line with her buttocks.
Slowly leaning back, she rested her head, and there were armrests on either side at shoulder height.
Her legs were similarly positioned, with footrests stretching down.
Placing her legs on these, her body felt like it was stretched out in a large "大" shape.
It felt more like a bed than a chair, but before she could think further, the manager finished preparing and restrained her limbs.
He secured her waist and thighs, preventing movement, and used rubber bands to fix her head and neck, making it impossible to lift her head.
"Nngh..."
The only parts she could move were her fingers and toes.
Being restrained was nothing new, but the uncertainty of what would happen next, with her vision obscured, filled her with a vague fear.
"B62, are you scared? You don't need to be. The urethral training will end soon."
"Yes... Yes..."
Urethral modification was done purely for "fun."
Unlike the anus, the urethra couldn't be penetrated like a penis, nor could it be handled roughly; it was a sensitive nerve organ.
The goal was simply to make her a toy that her owner would enjoy slightly more.
As an awkward silence filled the air, the sound of tools shifting in a box caught her attention.
The manager brought a wheeled chair and sat under Heo Seong-ah's legs, resembling a gynecologist with a patient.
"Hic!"
A large hand silently pressed between her legs.
Opening just the top part of the suit to expose her urethra, finding the small urethral opening was difficult due to female anatomy.
Eventually, the manager opened her vagina fully and gently spread the moist opening to locate the urethra.
"Nngh... Huh..."
Just the touch on her sensitive area made Heo Seong-ah tremble with pleasure.
Her vagina seemed to be begging for penetration, but for now, only the urethra would be touched.
The manager used a small plastic ring to keep her vagina open.
The constantly closing opening was held wide by the ring, exposing the pink vaginal folds, the urethral opening, and the hidden clitoris.
The flow of fluids from her vagina was quite erotic as it pulsed with each contraction.
The manager almost touched her vagina but restrained himself, focusing on the urethral opening.
"Huh..."
The urethral opening was very small, so small that inserting a cotton swab would be difficult.
He brutally stimulated the tiny opening with his finger.
"Nngh... Huh..."
Each gentle stroke made Heo Seong-ah's lower body tremble.
The sensation was different from pleasure; it felt like her bladder was full and about to release urine.
"B62, how do you feel now?"
"Nngh... Huh... It feels like I need to urinate..."
"Hmm... Understood."
After a day of continuous climax, the manager wondered if her urethra might already be damaged, but it was an unnecessary concern.
He examined Heo Seong-ah's urethra and took out a thin rubber tube, applying lubricant to the end.
"I'll insert it. Please relax."
"Huh..."
Without hesitation, the manager inserted the tube.
Anatomically, a woman's urethra is very short, typically around 5 cm, though it varies greatly from person to person.
Heo Seong-ah's urethra reached her bladder at about 6 cm.
"Huh..."
It didn't feel like it was fully inserted.
Instead, yellow urine flowed out through the tube.
To avoid causing bladder damage by pushing further, the manager recorded the depth of her urethra and selected appropriate training tools.
Meanwhile, urine flowed from the discarded tube.
Gurgle—
"Nngh... Huh..."
As the waste left her body, she heard the humiliating sound.
Heo Seong-ah clenched her lips in frustration, unable to control her urination.
Though her face couldn't be seen, she was likely closing her eyes in shame.
"B62, note that urethral training isn't as difficult as anal training."
"Yes..."
"There are three things you must do during this training."
"What are they?"
"One is to develop the habit of urinating messily whenever you climax.
Another is to enhance sensitivity so you can climax whenever you urinate.
The last is to learn to hold your urine until your owner allows it."
"Yes...?"
Both tasks seemed easy when described.
Making a mess while climaxing was similar to the fluids she had been releasing.
As for holding urine, anyone could control their bladder, couldn't they?
Heo Seong-ah didn't fully understand the purpose of urethral modification and remained calm, choosing not to speak.
"Let's begin."
"Yes, sir..."
As the modification started, Heo Seong-ah regretted her complacency and began to struggle.
"Nngh... Hic!!"
"Don't move. If you don't stay still, I'll have to restrain even your fingers and toes."
"Nngh... Huh..."
After the urine had flowed out, a syringe full of medication was attached to the end of the tube, and the piston was pressed.
Just the sensation of her bladder expanding made her react wildly.
The modification hadn't begun yet; this was just a preparatory step for urethral training.
"Nngh... Huh!!"
One syringe held 100 ml.
Only one dose had been administered so far.
Considering the average bladder capacity of an adult woman is about 300 ml, she should be able to handle it easily.
"Nngh... Huh..."
As soon as the syringe was removed, the medication flowed out through the tube.
The manager immediately blocked the end of the tube with his finger and connected another syringe, pressing the piston.
"Nngh... Aaah!!"
The medication flowing through the tube was pushed back up.
The pain from her bladder expanding was unbearable for a normal woman.
"Nngh... Aaah!!"
Was it pain?
It wasn't really pain; it just felt like she urgently needed to urinate.
The problem was that no matter how hard she tried, she couldn't hold her urine, and the fear of her bladder bursting was stimulating her nerves.
"Nngh... Huh... No!!"
The manager connected a third syringe and pressed the piston.
The pressure was stronger than before, but 300 ml was still manageable.
"Nngh... Haa... Aaah!!"
After finishing the medication, the manager blocked the end of the tube with his finger.
Heo Seong-ah's bladder, which had never been stretched this far before, bulged visibly under her abdomen.
