Anal Development (2)
Twitch, twitch... The anus brushing against the air wriggled cutely.
The manager, who had declared he was about to begin the training, held his breath in silence without laying a finger on Heo Seong-ah's anus.
"Mmph... Ugh..."
No sounds reached her. She couldn't see a thing. Dreading the stimulus that might spring forth at any moment, Heo Seong-ah made her anus twitch.
"Huuup..."
The longer time dragged on... all her nerves, independent of her will, zeroed in on her ass. Now that the aphrodisiac had warped her anus into an even more sensitive organ, the manager—who had been watching patiently—finally extended his hand.
"Uup..."
Slowly... oh so slowly... it approached the anus of Heo Seong-ah, who was innocently wriggling her hips in ignorance.
Clenching one hand into a fist, he pressed hard against the base of the dildo lodged deep in her anus.
"Kuuup!!"
The intestinal mucosa clinging to the dildo stretched pliantly, sending waves of tearing pain through her flesh. Her utterly ruined anus accepted even that agony as pleasure, driving her to a mind-shattering climax.
"Kuuuup!!"
Letting out a beastly scream, she arched her waist. Her pussy throbbed obscenely, squirting a gush of fluid—but the latex suit blocked any view of it.
"Excellent. B62, you're performing exactly as I expected, even without instructions."
With her body fully restrained, the only thing she could move was the anal sphincter peeking out between her cheeks. This was training meant to make her realize a life where her entire body had become a sex organ, her anus the core of her very existence.
"Uuup..."
Most women at first felt instinctive revulsion, making it hard to derive pleasure from it. Plenty harbored disgust at the mere idea of pleasure from an organ meant for excretion.
But... Heo Seong-ah, with her innate talent as female livestock, was the exception.
"Excellent. Simply excellent."
"Huuup..."
Unable to hide his delight, the manager stroked her ass with a beaming smile.
"At this rate, B62, your anal development should proceed smoothly."
"Mmph.."
"Then let's begin the proper training."
He dipped his hand into the jar of aphrodisiac, then withdrew it, clenching and unclenching his fist to spread the liquid evenly. Right after, he gripped the base of the dildo buried in her rear hole.
"First, we'll remove the dildo. It might hurt a bit, but grit your teeth and endure."
"Uup..."
The dildo inside Heo Seong-ah's anus was shaped like an anal plug at the end, with a bulbous bead that wouldn't come out easily. Once inserted, no amount of clenching could expel it on her own. At 6cm thick, even forcing it in while she slept had been a struggle. If insertion hurt that much... extraction would be hell.
Well, compared to the training ahead, this was nothing.
"Uuuuup!!"
He'd barely tugged, and it felt like her entire guts were being yanked out. With the dildo measuring about 40cm long inside her, the pain wasn't imaginary.
"Kuuup!!"
"B62, thrashing like that won't end it. Relax and take deep breaths."
Heo Seong-ah hunched her waist awkwardly, her body shuddering. Agonizing cramps like severe diarrhea hit her, cold sweat pouring from every inch of her skin.
"Uhup... Huuk..!"
Her lower belly tensed, compressing her innards. Her throat was already blocked, breathing a chore—now her lungs felt crushed, suffocation closing in like death itself, making her tremble violently.
Of course, the manager didn't stop.
"Uuuup..!"
"Haah, B62, must you disappoint me like this after starting so well?"
"Huup..."
"If you're not coming out... do you plan to live the rest of your life with it in?"
"Uup, uuup..!"
Anything but that—she'd rather die. Summoning her last reserves of strength, Heo Seong-ah shook her head side to side.
"Then relax your ass and accept it. Stay like this, and you might really break."
"Huup..."
Break... A vital part of her body since birth... ruined so pathetically it'd plague her forever...?
That single word "break" terrified her beyond reason. Trembling, she lowered her waist.
"Huuup..."
She tried to relax... willed her body to loosen as much as possible... squelch—
"Kup..!"
The moment the manager tugged lightly, her sphincter clenched reflexively. An involuntary bodily response, beyond her control.
"Haah..."
At this rate, they'd be stuck for hours. Sighing, the manager furrowed his brow in irritation and yanked the dildo with force.
"Kuuuup..!!"
Her sphincter stretched beyond its limit, the anal folds blooming open. The hidden base of the dildo emerged bit by bit toward the outside.
"Kuuuwup!!"
Like a hen laying an egg... the massive 6cm bead appeared at her anus. But at its thickest point, it caught—no further progress despite the pull.
In the end, the manager released his grip.
"Kup..?!"
The bead slipped back into place. Heo Seong-ah, who had buckled at the sudden pressure, barely steadied her near-fainting body and focused on breathing.
"Huup... Huup..."
Oxygen deprivation might kill her before the anal pain did.
"Haah... B62, your tightness is praiseworthy... but keep resisting like this, and we'll have to use our methods."
"Uup..."
What the hell did that mean? She couldn't even imagine.
The manager patted her buttocks with his palm and commanded.
"Last chance. Relax and take it like a good girl."
"Huup..."
Inhale, exhale... Her anal sphincter wriggled back and forth in time with her breaths. The moment he timed his tug, Heo Seong-ah reflexively tensed her lower belly, clamping down on the dildo.
"Damn it..."
Furious now, the manager gripped the dildo and wrenched hard.
"Kuuup..!"
Caught again at the thickest part... This time, he rammed it back to the hilt.
"Kuuuuup!!"
Squelch-squelch-squelch— Ruthless pistoning without a shred of mercy. Each crush of her innards brought nausea and a bizarre new pleasure she'd never felt.
After dozens of repetitions, without warning, he braced his forearm and yanked the dildo free. Finally, the 6cm bead emerged from her anus.
"Kuuup..!"
Her ass felt like it was on fire. The torn sphincter throbbed with raw pain, but thankfully, no major bleeding.
"Huu... I told you, didn't I? Keep it up, and we'd do it our way."
"Huuup..."
"Then the rest goes our way too."
Now the real ordeal began. Extracting the full 40cm dildo was still far off.
The manager seized the protruding dildo with both hands and pulled like he was hauling a rope with all his might.
"Kuuuuuup..!!"
The snake-like silicone slithered out endlessly. Her anus everted comically around it.
"Kuuuuwuuup!!"
The extracted dildo coiled between her legs. What was supposed to be 40cm stretched past 60cm before it ended. At last, the tip popped free, the pressure on her guts vanished, and Heo Seong-ah hit climax amid the refreshing relief of excretion.
"My mistake. Looks like something other than the dildo I mentioned got inserted... No wonder it's too thick to remove yourself."
Intentional? Whipping the 60cm long dildo like a lash, the manager picked up a smaller silicone brush. Drenching it in aphrodisiac, he gently rubbed her still-gaping, twitching anus.
"Uup! Mmph..!"
Blissful pleasure after the brutal pain. Carrot after the stick. The most effective training method of all.
"Uuwup..."
The hole meant only for excretion... was slowly, gradually transforming into a nexus of pleasure.
Each brush stroke made her anal folds twitch lewdly.
"Huuup..."
Coating her anus until it glistened with aphrodisiac, the manager casually tossed the brush back into the jar and prepared for the real training. Just like with her throat expansion, an array of dildos in varying girths and lengths awaited for her rear hole.
"Oh, right, B62. Before we start, here's your chance to defecate."
"Uup..."
"You haven't eaten in days, but it's built up, hasn't it? Go when I give you the chance. Understood?"
"Mmph..."
Perhaps her first and last chance to relieve herself. The manager unbound her restraints.
"Please, make yourself comfortable."
Unlike his courteous tone... for some reason, he smirked with a sinister curl of his lips.
