Excretion Training (5)
The inner flesh that had flipped inside out swiftly returned to its place, contracting the anus. The anal plug mercilessly bored into the narrowed opening, passed safely through the colon, and sank to the hilt. Then the Manager yanked it out in one brutal pull.
"Gguuuuueup!!"
How much better it would have been if it were just a plain dildo. The bumpy surface, like a cluster of grapes, offered no chance to grow accustomed to the stimulation, spreading fresh waves of pain without mercy.
"Uueup..!!"
She'd long since given up begging for mercy. Heo Seong-ah simply yearned desperately for this ordeal to end, relaxing her body as much as possible and breathing slowly.
"Huuueup... Huu..."
The promised number of repetitions wasn't over yet, and without a moment's rest, the Manager continued ravaging her anal hole.
Squelch—
"Gguuuuwuup..!!"
After growing somewhat accustomed to the stimulation, the pain began to fade. Part of it was due to the nerve cells in her intestinal mucosa dying from the extreme agony, but the main reason was that her rear hole had expanded into a more usable shape.
Pleasure rushed in to fill the void left by the pain.
"Huuueup..."
On the final tenth pull, as the dildo was extracted, Heo Seong-ah arched her back like a bow and squirted forcefully.
"Well done holding out, Livestock Number B62. That's the end."
"Huuueup..."
The moment she thought it was truly over...
Squelch—
"Gguuuueueup!!"
For some reason, the anal plug invaded again through her loosened, slack anus. Thrust to the hilt and pressed down hard, it made her sphincter, which she'd barely managed to relax, clench painfully tight.
"Gguuueup!!"
Heo Seong-ah screamed, resisting the ecstasy that threatened to make her pass out.
"Uueup..!"
"You should be able to do it on your own now, right? Get to it."
Do it...? What the hell was he talking about?
"Uup..."
Oh... She'd forgotten. The original goal was to remove the anal plug herself.
"I did tell you to do it yourself... but that position makes it look impossible."
Face-down in the beastly doggy position, ass thrust high—how could she possibly manage it like this?
The Manager unbound her limbs and removed the ball gag from her mouth.
"Buuueeek..."
A thick, viscous fluid poured out, stringy and unbelievable as human saliva. It was like spitting out a mouthful of glue.
"Gguuu... Aah..."
Her jaw muscles had clenched so hard around the ball gag that she couldn't easily purse her lips. As her jaw rattled uncontrollably, translucent drool trickled down her chin.
At this rate... what was the point of unbinding her? Not human, but beast. No trace of humanity left in her vulgar, debased form.
Then... she deserved no human treatment.
Smack—
"Kkuk..!"
The Manager unleashed a powerful spank on Heo Seong-ah's ass as she lay there dumbly trembling. The latex suit dulled the pain, but the impact shoved her face-first to the floor with a sharp intake of breath.
"Livestock Number B62, since you keep forgetting, I'll remind you again. You have no human rights. Acting on your own whim is absolutely unacceptable. No matter when, where, or what happens, you will obey the Manager's orders without refusal."
"Hic... Uuuk... Y-yes..."
"What are you doing? Think about why I unbound you and hurry up—get into position and remove the anal plug."
"Kkuk... Uuuk..."
Why had the Manager unbound her? To remove the anal plug in a position easy for excretion.
It was obvious if she just thought about it. Heo Seong-ah barely moved her limp limbs and squatted down, thrusting her ass back, hands clasped in front to gently press her lower belly. Just like squatting over a squat toilet to defecate.
She tensed her sphincter to pull out the plug, but before she could, the Manager's massive palm slapped her ass.
Crack—
"Heuk!"
"Haa, waiting position."
He taught the livestock-ignorant Heo Seong-ah the proper posture himself. Realizing her mistake, she hurriedly spread her legs wide horizontally, sat down, and clasped her hands behind her head.
"Uuuk..."
With heels lifted and back ramrod straight, balancing was no easy feat. Tensing her sphincter in this state... honestly felt impossible even before trying, making her hesitate.
"Uk... Hic... Khuuk..."
But she had to do as ordered. She focused on her anus.
Indeed, it moved more easily than before. With each clench and release of her sphincter, the anal plug slid outward bit by bit along the slack intestinal walls.
"Kkuk... Huguk..!"
A pleasant pleasure, like accumulated waste finally escaping, washed over her as the plug's base peeked out from her anus.
"Kkehaang... Haa..."
Just lightly stimulated by the bumpy dildo's surface, Heo Seong-ah nearly lost her mind in the moment.
"Huuueuk..."
She hunched her back... trembled all over... her twitching thighs gradually drew forward together.
"Gguuuu..."
Sticky saliva dripped endlessly from between her slightly parted lips. Eyes blindfolded, her expression was hidden, but she was certain it was a pathetic sight.
The Manager lightly smacked her halted ass.
Crack—
"Kkehak..!"
"Livestock Number B62, what are you doing? Hurry up."
"I-I'll do it... Haa..."
Only the tip had barely emerged. Far from enough to extract the full 20cm anal plug.
Calming her mind, Heo Seong-ah spread her legs wide horizontally again and tensed her ass.
With her sphincter twitching open and shut... lewd fluid dripped from her pussy, untouched by stimulation.
"Haa... Hau..."
The Manager's massive palm swung toward her ass once more.
Crack—
"Kkuk..!"
"Haa, I gave you special training because you couldn't remove the plug yourself, and you're still showing this idiotic behavior? Do you think it's right to ignore the Manager's good intentions and drip pussy juice just because it feels good?"
"Hic, khuuk... I'm sorry..."
She had nothing to say but a heartfelt apology. He was right about everything, from one to ten.
The only injustice was... her body had been modified to make it inevitable.
"Khuuk..."
Heo Seong-ah bit back any excuses and strained desperately to expel the anal plug. Teeth gritted, body shuddering, she clenched her sphincter—but the thick plug refused to budge.
No... a little more effort, and she could do it herself.
The problem was, each clench stimulated her aphrodisiac-sensitized walls with the bumpy surface, flooding her with pleasure that slackened her muscles. The plug, which had nearly emerged, slid back in reverse.
Each clench made it seem like she was gripping the dildo herself and shaking it back and forth—a vulgar, debased spectacle.
"Khuuk..."
Trapped in this vicious cycle, Heo Seong-ah finally realized it was impossible and hung her head, sobbing.
Terror of the coming punishment gripped her.
"Hic... Heuk..."
"Haa... Tears won't solve this. You know that, right?"
"I'm sorry... Heuk..."
"Sorry won't cut it either. If you can't even remove a single plug like this, how do you plan to excrete in the future?"
"Heuk..."
This was different from usual training. It wasn't "can't"—it was something a female livestock must do.
"What's the problem? Tell me."
"Y-yes..?"
"Explain why you can't do it yourself. We should improve what can be improved and move forward."
"Ah... Heuk..."
For some reason, right now... it felt like the Manager would listen to anything.
"It's... well..."
"Speak freely when given the chance."
Too thick? Uncomfortable position? Sore anus? Weak strength? She could say anything, but instead of immediate fixes, Heo Seong-ah thought of the future and slowly opened her mouth.
"My ass... is too sensitive... it's hard..."
Her aphrodisiac-modified rear pussy was too sensitive. So... remove the silicone bumps, weaken the aphrodisiac, anything—her desperate plea.
"I see. So, your rear pussy is too sensitive, making it hard to exert force and excrete as you intend?"
"Heuk... Yes..."
"Understood."
The Manager accepted her opinion readily.
But his solution... was worlds apart from what she'd imagined.
Squelch—
"Hiiik!"
A cold palm in latex gloves pressed against Heo Seong-ah's pussy. It gently cupped and squeezed her slick, nectar-soaked mound.
"I'll solve Livestock Number B62's problem."
"Y-yes..?"
How...? Sudden unease flooded her, but as always, such feelings came too late.
