Anal Conditioning: Shattered Depths
Kimiro, the slave trainer, relentlessly smacked Yujin's plump buttocks. Her ass rippled like gentle waves with each blow. Yamato licked his lips at the mesmerizing sight.
Kimiro slathered a sticky liquid on both hands and began inspecting Yujin's asshole from every angle. His fingers groped her cheeks with obsessive thoroughness. He didn't forget to roughly spread them wide and peer deep inside. The sudden sensation of her ass being pried open made Yujin tremble, even through the haze of drowsiness clouding her mind.
In that instant, Kimiro's finger forced its way in while holding her cheeks apart. The finger itself wasn't cold, but the chill of the liquid coating it sent shudders through her body.
"Ughhh..." A raw, instinctual groan escaped her lips.
"Don't make those weird noises. Relax your ass, or you might tear. "
"Not... not there..."
"Don't talk nonsense. I'll develop it slowly, so just accept it. Once you're used to it, it'll feel way better than your pussy."
Kimiro's thick finger pistoned in and out of her asshole. Not content with mere thrusting, he bent and twisted it inside, stirring her depths. The sensation—utterly alien from anything in her pussy—drew hoarse screams from Yujin's throat.
"Inside... it's... hiiit... please, let me rest... please...!"
At her tear-choked plea for respite, Kimiro wrenched her asshole wide open. It had long surpassed any normal limits of stretch.
"Fine, I'll give you a break. Your break lasts as long as you can endure this."
He shoved an unidentified suppository deep into her gaping hole.
"That's your rest time—until it melts."
She thought her longed-for respite had finally arrived. But Yujin couldn't stifle her shallow moans.
"Hah... haaah..."
"Looks painful, doesn't it? If you want real rest, stop panting like that."
The emotion churning inside Yujin was simple: not pleasure, but agony—like her asshole was ablaze. Even a red-hot iron rod couldn't burn like this. She clenched her teeth, desperate to hold back the building excretion urge, but her body was merciless. She couldn't last even five minutes before her lower belly went slack. The melted suppository oozed slowly from her asshole—a scene straight out of an erotic masterpiece. Kimiro gazed in admiration at the clear, transparent flow.
"President, it seems you've done a thorough enema."
The suppository also served to absorb feces. It usually emerged cloudy, but the liquid trickling from Yujin's hole was nearly identical to its original hue.
"Still, we need to check precisely."
Kimiro lifted a rubber plug attached to a balloon.
"Air enema device. Perfect for expelling the last remnants. And it's useful even beyond shit."
He fitted her with enema panties designed to seal in the air. Yujin shuddered at the tight squeeze around her pussy.
"Let's begin."
With each squeeze of the rubber pump, air whooshed through the hose into her. After relentless pumping, her lower belly ballooned outward. Similar to a liquid enema, but far more bloated.
He removed the hose and kneaded her swollen abdomen firmly.
"Don't hold back—let it all out."
Gurgling sounds rumbled as Yujin twisted in agony. She writhed for a while, but the direct pressure proved too much. Overwhelmed by the excretion urge, she finally let go.
Pffft! Prrrbbrbrrbt! Fierce farts erupted in succession. Aside from the stench, nothing solid emerged. Relief washed over her at first, but her expression hardened as the blasts continued. Her face flushed crimson like a blush—undeniable proof of how thoroughly she'd been cleaned.
Kimiro, hands freshly coated in the slick liquid, caressed the area around her ass. His left hand delicately rubbed her labia minora, drawing lewd moans from her lips.
"Hah... ahhn."
His right hand merely soothed the rim of her asshole to relax it fully. Even as his left poked at her clit and lips, the right stayed dutifully on task. All Yujin could do was moan in pleasure while nursing her anxiety. Her wanton cries delighted Kimiro.
Yujin had never even possessed proper knowledge of anal sex. To her, that hole was an unknown frontier. The terror of exploring the abyss was absolute for any human—each of Kimiro's actions filled her with dread, clenching her body tight. In other words, tightening her anus.
After prolonged rubbing, a thin intestinal fluid began to leak from her rear. Only then did Kimiro nod in approval.
"Looks like we're ready to begin."
To Yujin, it felt like clenching now would force out shit. That was the "prepared" state? One thing she didn't know: no matter how it felt, everything had been expelled—nothing left to come. And that very sensation was what clenched her anal ring.
Kimiro picked up a tool studded with bumpy protrusions—anal beads, twice the length of her finger. They slid cautiously into her hole. The greater girth and depth wracked her body, bending her in sobs.
"Hah... hngg... oooh..."
Her cries were utterly different from those during pussy play. Yamato burst into hearty laughter at the novelty.
Her rear was already hypersensitive—not meant for insertion. The perverse reversal alone was intense, but the beads delivered unintended jolts, forcing unfamiliar pants from her throat.
Kimiro sneered, toying with the beads. He'd pull them halfway, then thrust back in, repeating to savor her reactions.
"Writhing like that—feels that good?"
She wanted to scream it felt awful, disgusting. Unlike before, her mouth was free of a gag. She opened it to shout... but... her mouth refused. It craved the pleasure instead.
"You've got real talent for anal. I'll personally turn you into a crazed anal bitch."
Kimiro's eyes gleamed.
For the next two days, Yujin endured nonstop anal training without sleep. The first day alone pulverized her pride. Kimiro fed fist-sized beads into her ass one after another. Whether it was his desire or Yamato's hardly mattered—one truth was certain: it aimed to utterly destroy her.
Right now, the training was utterly humiliating. A vibrator buzzed against her clit, her ass framed and spread by special panties, and she had to count the beads entering her hole. Fail, and it continued until correct. Succeed, and after a brief rest, it started over.
"How many have gone in now?"
Humiliating as it was, Yujin sensed four. Fewer felt too empty; more, too vague. The distinct fullness hit exactly at four.
She opened her mouth cautiously. "F-four... four..."
Kimiro flashed a sinister grin. "Wrong. Can't even count properly, like some pampered lady. How much more trouble will you make me go through? Clench tighter."
"Y-yes... I'm sorry... and thank you..."
The rules during training were simple: apologize for mistakes. And never forget to thank Kimiro for conditioning her ass.
"A sow who cums from her ass was never gonna count right anyway."
He yanked the beads out viciously. Yujin buckled, strength fleeing her waist. Blindfolded as ordered, her arms alone chained to the ceiling.
"Again. Won't stop stuffing your ass until you get it right. Focus properly."
With those degrading words, the anal beads plunged back in without mercy. One thrust in, one pull out—and already today, Yujin had climaxed from her ass countless times. Concentrating sensation there only accelerated her peaks. The initial pain of insertion had long transformed into ecstasy. Unbeknownst to herself, she began craving those anal orgasms.
