Pain Far Beyond the Unforeseen Modification's Ecstasy
"Aaaahhh...!!"
Heo Seong-ah bent at the waist, trying to escape the stimulation by hunching forward, but the Manager gripped her hips firmly, holding her in place.
"We're still a long way from done. If you're like this before we've even started properly, what are we supposed to do? Just endure it quietly, please."
"Kkuuuh... Kk!"
Endure it quietly? As if that were so easy...
"Aaaahhh...!!"
If her anus had been in a normal state, she might have gritted her teeth and borne it. But now that it rivaled her pussy in sensitivity, Heo Seong-ah could only thrash wildly as pleasure surged through her mind like it would split her skull open. On top of that, deep inside her guts—far from pleasure—came agony. It felt like sharp blades slicing her innards, followed by red-hot needles stabbing relentlessly.
"Agh... Aaahhh...! Haaang...!!"
The ecstasy from her anus clashed out of rhythm with the torment deep in her body, assaulting her brain nerves. Heo Seong-ah screamed in a cracked voice, driven mad by the sensations.
"Aaaahhh...! Hic! Kk... Uhk...!"
"Just a little more now."
The deeper it went, the stronger the tension pushing the dildo out. When the last centimeter refused to budge, the Manager pressed both hands firmly on the base.
"Kkuuuuh...!"
No matter how hard he pushed, it wouldn't go further—and the expelling force even made it slip out bit by bit.
"Hmm..."
Getting it this deep was impressive enough. Still... once started, shouldn't he see it through?
"Livestock Number B62."
"Kk, haa... Uaa..."
"Livestock Number B62!!"
"Y-yes...!"
"Haa, please pull yourself together."
"S-sor... I'm sorry... Hic..."
When she just panted like a beast lost in pleasure, ignoring his words, he had to snap her out of it like this sometimes. She could probably use a bit more stamina training... Though completely breaking her didn't sound half bad either.
"Livestock Number B62, just a little more and it'll be over. Understood?"
"Y-yes..."
"It doesn't seem like it'll go any further, so we'll proceed our way. It might hurt a bit, but don't pass out, please."
"Y-ye...s...?"
No sooner had the words left his mouth than the Manager reached out with his left hand, pressing down gently on Heo Seong-ah's waist as she lay prone. Even though she'd bent to her limit, he forced her torso flat to the ground.
"Auk..."
Her ass stuck up obscenely in the air, a humiliating pose imposed on her. Still pinning her waist to prevent movement, he reached down with his right hand to the slightly protruding base of the dildo.
But then—thunk—
"Eh...?"
Instead of grabbing it, the Manager clenched his fist. Like hammering a nail, he lightly tapped the dildo—thunk thunk—to lock it in place.
"Uk, kk, uuk..."
Even those light impacts sent pleasant vibrations through her; Heo Seong-ah shuddered violently, swallowing moans.
"Haaang..."
Now, lewd cries spilled from her lips like habit, exhaled with every breath. Knowing that sweet voice would soon twist into screams of agony... The Manager's groin throbbed with excitement already.
"Livestock Number B62."
"Yes... Hic!"
Thunk—He timed the tap for when she answered, on purpose.
The protruding dildo plunged root-deep into her ass. Guts overridden, organs squeezed one by one in horrific sensation. Heo Seong-ah let out a final shriek and lost consciousness.
"Haa, passed out already?"
He'd expected it, but fainting from just this much pain? He'd hoped for a different reaction... The Manager gazed at her sprawled pathetically, unable to hide his disappointment.
Livestock had no right to peaceful rest. Especially now, passed out from extreme agony, she should snap awake and fawn over her owner. "Sorry for fainting, I'll endure better now"—wag her tail with cute words like that. That was livestock.
...Well, mental conditioning like that was the Shared Property Facility's job. Her future owner would mod her to his tastes anyway. If he wanted, they could do light drug-based brainwashing~~, but side effects were high, so not recommended.
"Haa, her future's... pretty bleak."
Not his business, but thinking of B62's fate, the Manager shook his head and pulled a telescoping baton from his coat pocket. He'd meant to whip her latex-sheathed ass, but seeing her tremble and sob, he changed his mind.
Pain needed pleasure to balance it. She'd suffered enough inserting the anal plug—enough to faint—so now it was time for sweet ecstasy to wake her.
The Manager slipped on latex gloves and reached between Heo Seong-ah's legs. He tore the suit's hole downward from the gaping anus, exposing her sopping wet pussy. Warm, humid pheromones wafted out, alluring to any male. Her hole twitched, leaking fluids nonstop—even unconscious, her craving for climax lingered. Maybe she dreamed of happy sex with someone. If so... the shock of returning to reality would break her mind.
"Livestock Number B62, if you don't wake up right now, something very bad might happen. Got it?"
No response, naturally, from the unconscious.
"I've warned you. Don't regret it."
The Manager pulled out his phone and called someone. An acquaintance from the Shared Property Facility's processing lab—he'd been waiting for the newly completed aphrodisiac.
Soon after, the training room door opened.
"Haa, Senior... I'm super busy too. Don't make me run errands like this~"
A young man overflowing with energy scratched his head as he entered. Unlike other staff, his white coat screamed researcher.
"Sorry, circumstances..."
Rule unbreakable: livestock and handler must share space to prevent bloodshed. Exceptions like livestock pens or annex training rooms existed, but not in an open space like this. Manager couldn't leave, even with her passed out. A tedious rule born from ancient livestock rebellions, now textbook history.
"Hmm, fine. But next time I need help, you come running, Senior! Got it?!"
"Haha, sure sure."
They exchanged typical senior-junior banter with awkward smiles. The researcher slipped a small vial from his coat and handed it over. Deep pink like artificial dye—this was the aphrodisiac. Barely 10ml in a pinky-sized glass bottle.
"You know we'll both be in deep shit if caught? Super dangerous."
"Experiments done, right? Livestock use approved, drug safety cleared too."
"No..! That's not it—this is me sneaking it out without permission?"
The researcher glanced around the empty room, whispering low.
"So, if busted, don't name me. Say you stole it yourself. Okay?"
"Got it."
He said that, but if caught, he'd confess it was the researcher's doing. Anyway, the facility's cameras covered every blind spot—trace the aphrodisiac, catch the culprit quick.
"Gonna go then... Be careful with it, Senior. You know? Works straight-up on men too."
"Does it?"
"Totally! Ugh, not my fault if it goes wrong."
Shooing off responsibility, the researcher fled out the door. How dangerous was this stuff...? Without the warning, the Manager might've handled it with just latex gloves.
"Ugh..."
Shuddering, he fetched thick welding gloves from a shelf box—leather, waterproof-coated against penetration. The box held more gear, but this sufficed; he closed it.
Why the protective equipment? Because handlers might inevitably need it. Protection was only for them... Livestock? No one cared if body or mind broke.
If Heo Seong-ah's eyes were open... seeing the box, realizing what it meant... She'd have panicked, thrashing in terror at her fate.
