Chapter 100: Excretion Training (2)
Ten times... twenty times... thirty times...
"Groooan..."
Heo Seong-ah, who had consistently toppled backward every single time the anal plug was yanked out, finally reached a stage after surpassing the hundredth repetition where she could hold out to some degree.
"Haaa... kgh..."
Of course, it was nothing more than gritting her teeth and enduring. In this position—legs splayed wide horizontally, both hands clasped behind her head, waist awkwardly hunched—even the slightest... really, the lightest prod of a finger would shatter her composure, sending her crumpling to the floor in a frenzy of ecstasy.
"Livestock Number B62, excellent. It took quite some time, but I want to praise you. You're holding up splendidly."
"Th-thank you... kghk..."
"Then please hurry."
"Y-yes..?"
"What are you doing? Surely you didn't think this was the end."
"Ah... ahk..."
Too focused on the sensations in her anus, she had forgotten. The act of pulling the tip of the anal plug free was merely the beginning.
"Kgh..."
The massive dildo clamped tight around her innards—a silicone behemoth nearly 20 cm long, its surface bumpy like a cluster of grapes—sent overwhelming waves of pleasure surging through her with even the slightest rub, enough to obliterate reason.
"Aaaang..."
The instant she tensed her sphincter to expel the anal plug, Heo Seong-ah's thighs quivered as she swallowed a moan. She barely kept her legs from clamping shut, fighting the bliss to maintain her posture.
"Haaa... aaang..."
Just once. Having nudged the anal plug out a mere 0.1 cm on her own, Heo Seong-ah grasped one undeniable truth: it was utterly impossible to remove it herself.
Separate from the effort of straining... the stimulation was far too intense; she felt like she might lose her mind. Tiny protrusions scraped her anal folds, teased the artificial intestinal lining, and the deepest 6 cm bead in her sigmoid colon toyed with her fragile sanity.
"Haaa... aaa..."
Impossible. Utterly impossible. And yet... no words of surrender escaped Heo Seong-ah's lips.
"Livestock Number B62, what on earth are you doing? Hurry up. Proceed."
"I-I'm... trying my best..."
"Is that so? It doesn't seem to have budged an inch."
The Manager teasingly extended his right index finger and flicked the slightly protruding anal plug.
"Aaaaang..!"
A mere vibration rippled through her, yet Heo Seong-ah's waist shuddered violently as her thighs clenched. Tension gripped her lower belly, and clear nectar overflowed from her tightly gripped pussy.
"Please hurry. As I've said repeatedly, I am not a man of infinite patience."
"Kgh..."
There was no time limit, no mention of punishment, no overtly threatening tone. And yet... terrified, Heo Seong-ah clenched and relaxed her anus frantically, like someone fleeing a pursuer.
"Kgh... haa... haaaang..."
When she strained, she gnashed her teeth, body trembling; when the plug edged out slightly, she released, letting moans spill free. Before long, a massive puddle of her ceaselessly dripping nectar had formed between her legs.
"Kng... aaang..."
After repeating the process countless times, Heo Seong-ah halted as if admitting defeat, gasping raggedly.
"Livestock Number B62, what are you doing?"
"J-just a moment to rest..."
"Who gave you permission to rest?"
For a mere beast to defy orders on a whim and demand a break—it was enough to stoke the Manager's anger.
"I-I'm sorry... hngk, but..."
"Enough. If you're thinking of pointless excuses, stay silent."
Any words beyond an apology would only fuel his ire.
"Haa... It seems you don't grasp the sensation of the anal plug yet. No helping it."
"Y-yes..?"
"Isn't that right? We've only inserted it so far—you've never once felt it being removed. You're hesitating out of fear of that unknown sensation, correct?"
Was that it? Could that be? As the Manager voiced her subconscious dread, he settled behind her back, pressing one hand firmly on her shoulder. One hand on her shoulder... then where was the other...?
"Hngk..."
An ominous chill crept over her. And as always, her instincts proved spot-on.
"First, you'll get accustomed to the sensation of removal. Then we'll resume excretion training."
"Wha—ah... Manager, waittaaahhh!!"
Drururuk— Seizing the anal plug, the Manager yanked it out without hesitation. Intestine-slick silicone nubs scraped her anal folds as it emerged.
"Groooaaah..!!"
Unlike before, when she'd controlled the pleasure herself... this forceful, brutal pull by another's hand delivered a dizzying ecstasy that nearly blacked her out. Yet it stopped short of climax—an excruciating torment.
"Eugggghh..!!"
Over half the 20 cm dildo slid free, and Heo Seong-ah clamped her legs tight, doubling over at the waist. Prostrated on the floor like a rear-entry bitch, she shuddered from the hips down, squirting wildly.
"Aaaaaang..!!"
She couldn't hold it back even if she tried. The problem? A third of the dildo still remained inside.
"Kgh..!!"
It had pulled out smoothly until it snagged somewhere. Likely the tip caught at the sigmoid colon's entrance.
"Livestock Number B62, relax and accept it properly."
"Kgh, eugh..."
She tried to loosen up, but once tensed, her muscles wouldn't budge. Her anus, overwhelmed beyond its limit, clamped shut, rejecting further stimulation. All that anal expansion training would be for naught.
"Haa... Relax quickly, please."
Paang, paang—
"Kheek..."
He slapped her ass to urge her on, but her sphincter stayed locked. She seemed to be trying her best to relax... but her futile twitching changed nothing. Like vaginal spasms during lovemaking between lovers—a bodily betrayal beyond her control.
"Haa... No choice, then."
The Manager gently released the gripped anal plug. Forcing it now might cause irreparable damage.
...Or not.
Even if it tore... it wouldn't kill her, right? Why coddle a beast during training? She'd be gone in days anyway, never to cross paths again. Besides... it should have slid out easily under normal circumstances. This snag was entirely Heo Seong-ah's fault. No matter her intent, her sphincter was clenched, blocking it. If it ripped and caused disaster, that too would be on her.
"Livestock Number B62."
"Hngk, eugh... Y-yes..."
"Don't hate me too much."
"Pardon?"
She flinched. Goosebumps prickled as primal dread surged; she tried to roll aside—but too late.
The Manager gripped the anal plug and wrenched it outward with all his might.
"Kheeeeeek..!"
The tip, hooked in her colon, ballooned her intestinal mucosa as it tore free. Countless nubs raked her folds with ever-changing torments, while the silicone mimicking her guts crushed inward, spreading suffocating agony.
"Aaaaaak.. haaang..!"
Pain..? Could she even call this pain? It was agonizing, grueling, maddening... yet why no simple "hurt"?
"Kh.. haaaaang..."
Heo Seong-ah moaned in euphoric tones, squirting uncontrollably. Her anus—now a second pussy—writhed in bliss under the dildo's merciless assault.
"Haaaaaaang..!"
"Haha."
Amused by her reaction, the Manager smirked and reached for her pussy.
"Eek... kheek?!"
She'd barely suppressed the ecstasy... but his gentle stroke shattered her. Heo Seong-ah thrashed wildly, wailing.
"Aaaaaaaaang!! Akgh! Hngk, aaaaaaaaang! Stooop!!"
Just rubbing side to side, yet her drenched nectar soaked his wrist. The anal plug wasn't fully out—the thickest base remained, the rest dangling like an animal's tail.
"Aaaaaaaaaang..!!"
Beyond her control, Heo Seong-ah wailed in rapture, collapsing fully to the floor, forehead grinding into the ground. Gasping as if dying, she finally went limp, feigning unconsciousness.
"Haa, passed out again?"
"..."
A sigh heavy with disappointment. Frowning, the Manager seized the plug and ripped out the final segment in one go.
Shluck—
"Kheek!!"
Her gaping hole bloomed open, insides everting. Like a rose unfurling, crimson mucosa protruded, mesmerizing.
"Aak... aa..."
This time, pain overpowered pleasure.
"Aaaak..!"
Screaming back to awareness, Heo Seong-ah rolled sideways, fingers probing her anus. Thankfully, her healthy body snapped it back into place swiftly.
