Rear Hole Development (4)
"Hnggh...!"
Gurrrrgle— It started from her stomach, gradually moving downward... Along with a sound like sewage draining, an excruciating abdominal pain gripped her.
"Looks like the signal came right on time? You're quite lucky. When we give you the chance to excrete, you should expel it quickly."
"Grhh...!"
Gurrrrgle— Something was rushing down at high speed. Her once-flat lower belly began to swell bit by bit.
"Aaaah...!"
Hold it in...? Impossible. She tried clenching her sphincter with all her might, but it slackened against her will. Finally, the excrement reached her anus...
Plop—
"Kyik!!"
It poked its head out from her anus. Just as the Manager had said, the colorless, odorless feces formed a smooth rod shape. It looked no different from the silicone long dildo that had been inside her moments ago. The problem was its thickness—around 7cm in diameter—and its indeterminate length.
"Aaaaaah!!"
Feeling her anus tearing, Heo Seong-ah bent her waist as far as it would go, cold sweat pouring down as her asshole twitched wildly. Anyone seeing her would think she was giving birth. The thought of having to show this sight every time she defecated from now on already made it impossible to hide her excitement.
"Grraaah!!"
She didn't want to shit. She wanted to hold it. No matter how hard she strained, the feces pushed out little by little, ignoring her will.
"Kaaaaah...!"
"Since you haven't defecated for two days, it's quite thick. It shouldn't hurt this much normally, but going through this ordeal on your first go... It pains me."
Obvious lie... Contrary to his words about it hurting his heart, the Manager smirked as he used the camera to close-up her anus.
A cute, pretty girl spreading her legs wide in humiliating defecation wasn't a common sight. Having scored good footage, the Manager snorted as he watched the feces emerge bit by bit.
"Livestock Number B62, at this rate, it might take over an hour just to finish. I'm fine with it, but what if your future owner won't wait?"
"Hic... Aah...! I'm sorryyy!! I'll shit faster...!"
Through the transparent feces, the wrinkled folds of her fully torn-open sphincter were visible. Rubbed raw and flushed bright red, her innards looked somewhat grotesque.
"Nnggh...!"
Heo Seong-ah trembled her legs, squeezing out every ounce of strength. Her face flushed beet red as she strained, then relaxed briefly before straining again to push out the feces. She repeated this about ten times, but there was no progress in speed. The protruding feces from her anus hadn't even touched the floor yet—only about 5cm extended.
"Aaaang... Haa... Aaang..."
Due to the excessive aphrodisiac effects, at some point, straining her anus caused her uterus to contract, spreading a pleasurable sensation.
"Haa..."
The Manager sighed as he watched Heo Seong-ah's body crumble from the pleasure. He had no intention of waiting idly until she finished naturally. There were mountains of tasks ahead. How long did she plan to waste time on this?
Squelch—
"Hguk!"
The Manager, gloved in latex, grabbed the feces dangling like a tail from her anus. Then... he boldly yanked it with force.
"Wooooogh!!"
Her anal folds flipped outward and clung. Along with the feces sliding out, Heo Seong-ah screamed like a beast and collapsed in place. Her ass pressed to the tray, she trembled her legs, letting out pained groans.
Regardless... she still had much more to expel.
"Livestock Number B62, get up quickly. I don't say things twice."
"Hic... Y-yes..."
She barely moved her limp limbs to resume the same position and posture. The transparent feces dangled like a tail, obliviously pushing out bit by bit... and the Manager yanked again with even greater force.
"Guwhoook!!"
Slide... The accumulated waste inside her gushed out with such momentum it felt like her intestines might come too. She desperately tried to pinch it off, but no matter how hard she clenched, it wouldn't budge.
Pop—
"Eek!"
Finally, the last of it was pulled from her anus. With no strength left in her hips, Heo Seong-ah toppled forward, forehead hitting the ground as her anus twitched spasmodically. The still-gaping hole tempted sadistic urges to ruin it further.
"Good. Very pretty, Livestock Number B62."
No stench at all—just a hole so alluring it could make cocks hard from looking. He could confidently say hundreds of men would line up for a fighting tournament with that hole as the prize.
"Huu..."
Expelling warm moisture as it slowly clenched—admirable effort. But... if they let it close as she wished, what was the point of the Shared Property Facility?
Now, it was time to ensure it could never tighten again... by thoroughly wrecking the sphincter.
The Manager pulled out a peculiar cylindrical device. Inside the metal cylinder, long metal rods extended in four directions: east, west, south, north. Designed to effectively expand the anus or vagina, turning the screw at the rod ends clockwise gradually widened the hole.
"Ughuk!"
To minimize pain and lubricate, he slathered it with aphrodisiac before shoving the cylinder boldly into her anus. Already, the anus folds splayed wide from its size, but the Manager didn't stop—he slowly turned the screw.
"Agh... Grk, kyaaaaah!!"
"Livestock Number B62, endure the pain. If you scream from just this, what will you do later?"
"Grk...!"
"It needs to gape much wider to become a proper hole. Understand?"
"Agh... Ahk..."
"Answer!"
The slowly turning screw suddenly spun half a turn faster. Feeling her anus tear, Heo Seong-ah wailed.
"Aaaah!! Ahk! Y-yesss!!"
"Good. Always answer the Manager's questions like that. Unless you want more pain."
"Hic, y-yes..."
Her anus was already gaping over 6cm. The lewd writhing of the folds between the cylinder captivated the eye. First, widen it fully to ruin the sphincter... then remodel the inner wrinkles with Botox injections and aphrodisiacs, transforming it completely into a pussy-like organ.
From today, Heo Seong-ah would become a vulgar woman climaxing every time a cock entered or she defecated. The natural fate of female livestock.
"Livestock Number B62, do you still think you're human?"
"Hic... N-no..."
"Then what are you?"
"I... sob, I'm female livestock..."
"Correct. Livestock Number B62 is female livestock to be used as a man's cocksleeve for life."
Her mistake was hoping for humane treatment. Time to break her body and mind more thoroughly.
"Right now, your anus is exactly 6.4cm wide. We'll make it 10cm by the end of today."
He asked no questions like "Can you handle it?" or "Will you endure?" Heo Seong-ah had no choices left. If the Manager willed it, it would be done—and she had to obey absolutely.
"10cm... Hic..."
Her anus, which had barely swallowed a finger... now expanded enough for a forearm.
"Hic..."
Just like during her mouth-pussy training, Heo Seong-ah felt primal doubt. Why expand the anus to 10cm...? Was wrecking it that much necessary for anal sex? What man's cock exceeded 10cm in diameter...?
From the user's perspective, wouldn't stopping at a moderate size be better? Heo Seong-ah's mouth twitched, but she clamped her lips shut, unable to speak.
Noticing, the Manager spoke first.
"Livestock Number B62."
"Y-yes...?"
"Something to say?"
"N-no... I mean..."
Should she speak? Or not? Fearing repercussions, Heo Seong-ah sealed her lips in silence.
"It's fine. Speak. Obedient livestock don't lose their right to speak. The mouth exists to speak—if you say nothing, isn't it useless?"
"Ah..."
Something in his words took root. A veiled threat: speak now, or he'd sew her mouth shut forever...
"And you're daring to ignore the Manager's command to 'speak,' sealing your lips?"
"N-no... I-I'll speak! I'll speak, so...!"
No choices left either way, Heo Seong-ah pried open her trembling lips and voiced her buried thoughts.
"I... um, Manager... hic..."
"It's fine. Speak."
"That is... so... hic... is this... really necessary...?"
"Pardon...?"
Catching him completely off-guard, the Manager couldn't hide his surprise at Heo Seong-ah's unexpected question.
