Rear Hole Development (5)
"Eugheeeek!!"
It hurt. It hurt... It hurt so much... She felt like she was going to die...
The Manager wasn't doing a thing... Yet the pain in her anus—held gaping wide—refused to fade, lingering relentlessly.
"Keuugh!!"
Heo Seong-ah could feel her sphincter breaking in real time.
"Kuaaaagh!!"
Her limbs twitched grotesquely as she thrashed in a desperate bid to shake off the agony. But if mere squirming could banish such pain... painkillers wouldn't exist in this world.
"Aaaaaagh!!"
"Livestock Number B62, does it hurt that badly?"
Was that even a question? Her hole was stretched at least three times wider than for a normal bowel movement... His tone dripped with blatant mockery.
Every time the Manager said something like that—knowing full well—he ignited a blaze of hatred in Heo Seong-ah's chest. Not that it mattered. She was just a helpless female livestock, incapable of even the slightest rebellion.
"Even if it hurts, you'll have to endure. I'll wait until you get used to the pain."
"Heuugh..."
She was certain she'd never get used to this torment, but after some time passed, the agony gradually ebbed, vanishing like a lie.
"Is it better now?"
"Heu..."
Heo Seong-ah swallowed her tears, drool streaming greedily from the dildo mask clamped in her mouth. She bent at the waist in silence.
The Manager coated his latex-gloved hand with aphrodisiac and rubbed it into her fully splayed anus.
"Haaah!"
From the gaping entrance, between every twitching anal fold, deep into the intestinal wrinkles... He smeared the aphrodisiac meticulously, missing not a single spot.
Once he'd painted every reachable surface, the Manager watched her flinching reactions with a faint smile. As the aphrodisiac dried, he reapplied it, repeating the process over and over.
"Hngh..."
With no time limit, he continued slathering it on. At some point, her inflamed red intestinal mucosa began writhing on its own, as if craving stimulation.
With each rhythmic contraction and release, her sphincter clenched, sending electric jolts of pleasure deep into her womb. Her body convulsed.
"Haaheuk..."
It was already a superb anal pussy, but the Manager didn't stop, layering on more aphrodisiac. Finally, he upended a canister and poured it straight into the hole.
"Ha-euk..."
The Manager waited patiently for full absorption. Then, without warning, he jabbed her anal rim with his index finger.
"Keurgh!!"
Even that light prod sent her into violent spasms, teetering on the edge of climax. There was no denying it—her rear hole had changed.
The problem? This was just the beginning.
"Now for the final procedure. It might sting a little."
"Keuheuk..."
The Manager fetched a suspicious leather case from the shelf. Inside were dozens of individually packaged 5ml syringes filled with orange liquid.
He took one, aimed at the squirming intestinal mucosa, and pierced it.
"Heuuugh!!"
"Endure the pain. It's all for your own good, Livestock Number B62."
"Heeeuk!!"
The sharp sting of the needle pricking her innards was no pleasure—it was alien agony. Even soaked in aphrodisiac, her flesh still registered pain. Heightened sensitivity doubled it, at least.
"Keurheeeuk..!!"
Heo Seong-ah twisted her waist, letting out a ridiculous scream. Unknown liquid flooded in from the syringe... and the puncture site swelled, puffy and soft.
Like fresh dough baked in an oven, a protrusion bulged from the once-smooth colon wall.
"No allergic reaction. Excellent."
"Heuugh..."
A permanent enhancement to boost sensation, ensuring lifelong pleasure.
"I'll keep going, so bear the pain."
"Uuueegh..!!"
Common Botox shots. The catch? Not for the face, but the anus. She'd heard of pussy Botox for better sex... but intestinal Botox? Unheard of.
"Keuhaaaagh!!"
"Continuing. Scream all you want—it won't stop me. Just endure."
No matter how excruciating, this was an essential modification step.
"Keuhaaaagh!!"
Her pitiful writhing softened even the Manager's resolve; he quickened his pace.
"Keuheeeeeugh!!"
Foamy saliva bubbled from her mouth amid the screams. Without the dildo mask, her throat might have torn, blood spraying.
That bad? Well, stabbing the delicate, untrainable insides of her body with needles—no wonder it hurt like hell.
"Kuaaaaaagh!!"
"Almost done. Just a bit longer."
In a mere ten minutes, hundreds of Botox injections bloated her intestinal mucosa like rising dough. Even with the speculum holding her anus wide, the silicone nubs blocked any view inside.
"Haha."
Gazing at her perfected anal pussy, the Manager couldn't hide his delight, bursting into laughter. Remaking a human woman's body solely to pleasure men... What could be more fun?
"Well then..."
Creating hundreds of internal nubs turned it into a cock sleeve rivaling any pussy. But the dense silicone might dull sensation... Her ongoing tremors suggested otherwise.
The Manager slid an aphrodisiac-slick finger inside.
"Keuheeeuk!!"
Against expectations, she felt it more intensely, shuddering as she hunched over. The narrowed passage gripped his slender finger tight, amplifying the foreign intrusion into pure ecstasy.
Inevitable, with all that aphrodisiac.
"Excellent, Livestock Number B62. A superb rear hole now."
"Haaah..."
"I didn't expect such perfect results. Your owner will love it."
A body more lovable by her owner... Joy or sorrow? Heo Seong-ah didn't know. For now, she focused elsewhere, trying to ignore the anal sensations.
Even now, with her anus agape from the nubs, it felt clogged. Like chronic constipation, an oppressive fullness. The nubs clung together, their weight vividly pressing, forcing her sphincter to clench.
"Heuuk..."
Clenching sent ripples through her pussy and womb—uncontrollable pleasure. A lifetime of this body loomed, horrifying.
"Rear hole modification complete. Removing the device."
Normally, prolonged training would heighten sensitivity and addict her to anal pleasure. But Heo Seong-ah had become self-addicted without it. Objectively, she was a prodigy as female livestock.
Pointless talent in this direction... Truly, every inch of her was sinful.
Grind grind—
"Haaah..."
The Manager reversed the speculum screws. Once small enough, he withdrew it slowly to avoid injury.
Her 10cm-gaped anus snapped shut, returning to normal.
"Healthy is best, Livestock Number B62... Next time, maybe rip the sphincter completely."
"Huuaah..."
Uttering such horrors, he removed her dildo mask.
"Uuwek..!"
The contracting throat never got easier. She gulped air and stifled a groan.
Meanwhile, the Manager unbound her limb restraints, seating her comfortably.
"Stay like that for a bit."
"Y-yes...? Yees..."
Hardship's end brings ease—or so the carrot-and-stick went. Sadly, this respite was brief.
"This'll do nicely."
Clink clink—
The Manager selected tools from the shelf, boxed them, and returned.
"Livestock Number B62."
"Yeess..."
"Pick a number from 1 to 10."
"P-pardon..?"
"Choose carefully. It'll be your lifelong companion."
His cryptic words left her dizzy with dread at the fork ahead.
