Added 2025-05-11 00:42:37 +0000 UTCEP.115 A New Weakness
A urethral plug 7cm long and 0.5mm thick.
Inserting even a smooth rod would be difficult, but the bumpy protrusions on the surface maximize the pain of expanding the urethra.
"Nnnngh!!"
The terrible urethral pain, incomparable to tearing the anal sphincter, wreaked havoc in her mind.
While the anus can expand somewhat due to repeated relaxation and contraction from feces, the urethra has a fixed diameter regardless of urine volume.
No matter how slowly one trains, forcibly tearing open the urethra is necessary.
For Heo Seong-ah just starting urethral training, that time came a bit early.
"Aaaaah!!"
"It's done."
Inserting the urethral plug wasn't too difficult.
Just push the lubricated rod into the urethra.
"Does it hurt a lot? You'll have to live with a plug this thick inserted for a while, so it's best to get used to it quickly."
"Ugh..."
The manager explained some anatomy about the clitoris and female genitals. When Heo Seong-ah seemed confused, he pulled on the plug slightly.
"Nngh!"
She felt a cramping pain in her lower abdomen as the protrusions came out. The manager pressed the plug towards her clitoris.
"Aaaah!"
The plug bent diagonally, expanding her insides further. She felt her untouched clitoris twitch and tighten.
"Nnnngh!!"
Her clitoris hurt. She felt throbbing pain each time the inserted plug pressed somewhere.
"Aaagh!"
"Relax. Take slow breaths."
"Nngh... Even if you say that... Ugh!"
Her groin burned as if her urethra might tear. The constant stimulation of her clitoris was agonizing.
"Nngh... Ugh... Aah!"
Ignoring Heo Seong-ah writhing in pain, the manager inserted the plug further and bent it. He even rotated it clockwise. Unable to bear the pain any longer, she grabbed his wrist with both hands.
"No more! Please... I can't..."
"B62, what are you doing?"
"Hic!"
Realizing her mistake, Heo Seong-ah could only hiccup in surprise.
"I'm sorry... But it hurts so much..."
"It always hurts at first. Are you going to give up immense pleasure because you can't endure the initial pain? Are you going to do something so stupid?"
"Hic..."
She didn't want immense pleasure or pain. She just wanted the training to end, but having no choice, Heo Seong-ah remained silent as usual.
"Hic..."
She released the manager's wrist and put her arms behind her back, vowing not to move.
"Good. It may hurt a bit, but please endure just a little longer."
"Nngh... Yes..."
As soon as he finished speaking, the manager thrust the urethral plug in deeply at an angle.
"Hic!"
The deep part of her urethra near the bladder entrance was pierced by the plug's pointed tip.
Though the blunt end wouldn't cause wounds, the pain of her sensitive insides being stabbed was indescribable.
"Aaaahn!"
She cried out, arching her neck like an animal.
As she wailed with her legs spread wide, the manager kept wiggling the plug as if searching for something.
After a while, he smiled with satisfaction and stroked her lower abdomen.
"Heek!"
Though she felt nothing through the latex suit, her lower abdomen convulsed unpleasantly at his touch.
"B62, it's done. This has fully exposed your 'true weakness' to the outside."
"Huh...?"
Her true weakness? She couldn't understand what the manager meant.
"What do you mean...?"
Heo Seong-ah repeated the question with a dumbfounded expression.
The manager explained further, but Heo Seong-ah still couldn't comprehend. He decided to demonstrate instead, grasping her swollen clitoris with his gloved hand.
"Eek!"
Just from her clitoris being lightly grasped, Heo Seong-ah let out a ridiculous scream and her body went rigid.
"Ah... Aah..."
Her body had no strength at all. Her clitoris was so sensitive that even breathing was difficult. Just being held, Heo Seong-ah's movements stopped as if a robot's off switch had been flipped.
All sound and movement ceased.
"Pfft."
The manager chuckled, amused by her extreme reaction to such a small organ. He rubbed her clitoris up and down with his thumb and forefinger.
"Nngh!"
Again Heo Seong-ah swallowed a scream, her waist trembling.
"Does it feel good?"
She couldn't answer the manager's question. All her nerves were focused downward, making it hard to even speak.
No wonder. Her normally tiny clitoris was now swollen to the size of a child's pinky finger joint.
The actual size was likely 3 times larger, but this seemed to be the limit for now.
"Now then, as a final gift I'll rub B62's favorite clit. Who knows? You might be able to climax."
"Nngh... Hic..."
The manager sat on her lower abdomen, spreading her legs wide and pinning them with his knees so she couldn't move.
"I'll make you feel an intense pleasure you'll never forget."
"No... Don't..."
Heo Seong-ah instinctively sensed danger in this pleasure. She tried to cover herself with trembling arms, but it was futile. At most she could only weakly pat the manager's back in resistance.
"Please enjoy it fully."
"No..."
Whether this pleasure would be a reward or trauma was up to Heo Seong-ah to decide.
Squish-
"Nngh!"
The manager grasped her swollen red clitoris between his thumb and forefinger.
Then...
Squish squish squish-
"Aaaaaaahn!!"
Without hesitation, he vigorously rubbed his fingers up and down.
