Urethra Training (3)
"Very nice, Livestock Number B62."
The sight of her body trembling and spraying urine everywhere in such an unsightly manner was truly a feast for the eyes. If she kept putting on a show like that, she was bound to become a beloved female livestock by her owner.
"Let's do it again, then."
"Guh... No moooore..."
He paused. The Manager's hand, gripping the rubber tube, froze in place.
"No more? Did you just tell me to stop?"
"Y-Yes...?"
Heo Seong-ah flinched in shock at the Manager suddenly latching onto her habitual slip of the tongue, assigning meaning to it like that.
"Do you think you're allowed to say 'no more' from your mouth, Livestock Number B62?"
"Th-That..."
"If you dare refuse the Manager's orders, and a mere female livestock like you can't even manage something as simple as holding your piss, then what's the point of keeping you around?"
"I-I mean..."
"Haa..."
Excuses spilled out before any apology or admission of fault. It was a habit of hers, sure, but from the Manager's perspective, it was infuriating.
"Haa..."
He kept sighing.
"How about we just rip your urethra open right now? Living the rest of your life pissing yourself nonstop doesn't seem half bad for you, B62. You can't hold it anyway and just leak everywhere."
"N-No, I don't want that...! I'm sorryyy!"
"Sorry for what?"
"Huh?"
"What exactly are you sorry for?"
She had to say something. Heo Seong-ah didn't think long and answered immediately.
"I'm sorry for not being able to hold my piss and keep leaking it..."
"That's right. You know it well enough."
The proper response had been set from the start. Heo Seong-ah had simply given the model answer.
"So, what should you do now?"
"Huh...?"
"You know your mistake, so what do you need to do to avoid repeating it?"
"Th-That..."
One mistake was just that—a mistake. But if it repeated two or more times... it was as good as intentional malice.
"That..."
The answer was predetermined this time too, but the words wouldn't come easily.
"Haa..."
With another sigh, the Manager supplied the correct response in her place.
"You need to undergo urethra modification, don't you?"
"Hic... Y-Yes..."
There was nothing left to say. It was her fault, so to avoid repeating the same error... urethra modification was essential. Realizing this, Heo Seong-ah bit her lip hard in humiliation and shame, swallowing her tears.
"Guhhh..."
Further talk was pointless. The Manager gripped the rubber tube again, rubbing its tip against her urethral opening.
"Gahaaaa..."
Every graze of the rubber tube's surface against her sensitive urethra sent a sharp sting through her, her strength draining away bit by bit. Perhaps from being forced to spray water so many times, her urethral hole was noticeably wider now, allowing the tube to slide in smoothly.
"Guh..."
The tube's tip reached her bladder... and the Manager resumed the process. Inject 300ml of aphrodisiac, then plug the end with a stopper.
"Ten minutes. Since it's your first time, hold out for ten minutes."
"Guuuuuh...!"
A simple training: fill the bladder with aphrodisiac and endure. Even this basic act had a definite conditioning effect.
"Gah... Ahhh..."
The first ten seconds, she gritted her teeth and held strong. But not even a full minute passed before fierce resistance set in.
"Aaaaaah!!"
Desperate to piss, she bore down on her lower belly, but the stopper jammed in her urethra let the pressure build with nowhere to go. Relax to avoid the stimulation, and the squeezing pain in her gut forced the tension back involuntarily.
"Guuuuuh...!"
Drenched in cold sweat from the unbearable agony she couldn't control, Heo Seong-ah writhed her only movable parts—her fingers and toes—in grotesque spasms. She let out gasps on the verge of passing out, her lower body jerking wildly. Each time she tensed, the urethral plug wobbled slightly back and forth, making the pussy hole beneath twitch lewdly. Her pussy craved release it couldn't have, leaking arousal fluid... but touching it was off-limits until urethra modification was complete.
"Three minutes done now."
"Guh...!"
It felt like at least an hour had dragged by... but the Manager's wristwatch showed only three minutes.
"Gah... Aaaaa...!"
It hurt—so much it hurt. The pain of anal expansion felt like nothing compared to this urethral torment.
"Gaaaaaaaah...!"
"Five minutes now."
"No moooore...! Guh, I really can't take it anymoreee!!"
Five minutes was all her gritted-teeth endurance had bought her. Once she left the Shared Property Facility as a proper female slave, she might have to hold her piss for hours. Even as Heo Seong-ah wailed and whined like a child, the Manager couldn't go easy on her.
"Kk! Uhk! Guh...!"
Her mind was on the brink of shattering from the superhuman urethral pain. Grinding her molars so hard they might crack, her sweat-soaked body heaved as she tensed her lower belly again. This time, the limit truly hit—the urethral plug nearly popped out from the pressure.
Well... with the long rubber tube still deep in her bladder, straining like that was pointless anyway.
"Gahaaa..."
The plug shifted out 0.1cm... then snapped back the instant she relaxed.
"Nooooo! Stoooop!! No moreeee!!"
Her thrashing pleas were a far cry from before. The true limit had arrived. Glancing at his watch, the Manager sighed regretfully and shook his head.
"Nine minutes now. Just one more minute."
"Guhhh..."
The final, cruel minute. With his latex-gloved hand, slick from aphrodisiac, the Manager stroked her pussy.
"Keeek! Guuuh!!"
He'd planned not to touch her pussy until urethra modification was done... but it kept twitching so cutely, how could he resist? This was part of the training anyway—no big issue.
"Gahyaaaaang!!"
He rubbed her favorite clit side to side, fast enough that his fingers blurred. Pussy juice built up inside erupted out.
"Gaaaaang! Aang!! Stooop!!"
"Why? Didn't you beg me to touch your pussy before?"
"Th-That was... not like thiiiis!!"
Stimulating her erogenous zones made tension inevitable, good or bad. Physiologically, clenching the pussy squeezed the urethral and anal sphincters too—so right now, Heo Seong-ah's bladder felt like it would burst from contraction, driving her out of her mind. Pain mingled with mind-numbing pleasure. In this state... if she could just piss...
How good would that feel?
"Gaaaaang...! Guhk, aaang...! Aang!"
"Ten seconds left. Tense up tight."
"Guuuuuh...!"
"Tense. Like when you're on the toilet pushing out piss."
"Guaaaang...!"
Tensing right as release neared contracted the bladder, expelling urine. Pairing orgasmic bliss with the relief of excretion would imprint on her body: orgasms and pissing go together. From now on, every climax would have Heo Seong-ah spraying urine like a vulgar slut.
"Now... three seconds."
"Guuuuuh...!"
"Two seconds. Tense up."
"Gahaa...!"
Her lower belly clenched hard, the bloated bladder's outline bulging visibly.
"One second."
"Kk!"
As the countdown ended, the Manager yanked out the urethral plug in a flash. Urine exploded from her bladder along the open path, and even then, he didn't stop rubbing her pussy.
"Aaaaaang!! Aaaaaang!!"
Spurt-spurt-spurt—piss from her bladder splashed against his palm, scattering left and right. It flew far enough to soak her pelvis, thighs, even her toes, dirtying the floor.
"Gaaaaang...! Aang! Aaaaaang!!"
Even after the flow ended, the Manager kept vigorously stroking her beloved clit until she was fully satisfied.
"How's that? Feels good, doesn't it?"
"Kk... Uhk..."
The ecstatic relief of releasing ten minutes' worth of held piss. Coupled with the clit stimulation firing her pleasure circuits. Denying it felt good would be an obvious lie.
"Say it. Does it feel good?"
"Gahaaa... Y-Yes..."
The Manager lightly stroked her pussy with his aphrodisiac-dripping hand. Now, even a light touch made her urethra contract, dribbling piss.
"Honestly, you don't really need urethra modification. You're a born whore—your pussy's always so wet anyway, right?"
"Guh..."
Born with a body that gushed fluids, Heo Seong-ah did squirt every time she masturbated, just as he said. Urethra modification was pointless for a soaked slut like her.
"That's why..."
The Manager picked up a grotesquely shaped urethra bead.
"We'll just expand your bladder capacity and call it done."
"Ahk..."
He said it scary-like... but it was just continuing what he'd planned all along.
