Either Or
Smack— "Eek!" Her pale ass cheeks jiggled like waves, swelling red in the perfect shape of a handprint.
The Manager said nothing... but it felt like he was silently urging her to hurry up and expel the anal plug.
"Gguuuuuh...!" Heo Seong-ah strained desperately at her sphincter. Thanks to the repeated expansions, she could push it out without too much difficulty, but the bumpy protrusions on its surface made it far from easy.
"Grroooh...!" Every push sent waves of pleasure surging through her. No matter how many orgasms she rode, she could never quite crest the peak. How she wished she could feel pain instead of this pleasure. There was no escaping this maddening stimulation on her own.
"Nnghaaa..." The relentless gush of pussy juices was nothing short of cruel. To anyone watching, it would look like she was blissfully climaxing from having her asshole prodded.
"Grroh... Hic!" When she'd managed to push the anal plug halfway out, the Manager's massive palm pressed against her pussy. Wearing the same studded glove as before, he lightly tapped her folds, then smiled at the sticky slickness clinging to his skin.
"Kk! Hic! Guh!" Even the stinging pain of those taps sent her reason flying with unbearable ecstasy. Her tensed sphincter halted the plug's smooth exit midway.
"Ggrroooh...!" She'd braced for the brutal clit-rubbing from before... but instead, the Manager seemed to be deliberately teasing her weak spots, merely flicking his fingers lightly against it. He circled the clit with maddening tickles or hovered his palm just out of reach, brushing ever so gently...
"Hngoooh... Kk... Haaang..." Driven mad by the agonizing tease, Heo Seong-ah forgot all about expelling the plug, consumed by the desperate urge to cum.
"Kk... Hng... Grrooh...!" I want to cum. I want to cum. I need to climax. If I could just go over the edge... I'd do anything.
"Gguuuuh... Haaaah...! St-stop. Pl-please..." She wanted to beg him to stop. Any more, and she'd truly lose her mind.
"Grroooo..." But... one wrong word, and who knew what horrors awaited. Heo Seong-ah clamped her mouth shut and endured.
"Hng...! Guh...! Kk...!" Her thighs kept spasming, shifting her balance backward. One slip in strength, and she'd collapse. She fought to hold on, but it wasn't enough.
"Aaaang... Haa... Uhng...!" Her legs finally buckled, knees drawing forward as her ass slammed back.
"Kk... Eek...!" The half-emerged plug crushed between her cheeks, sending a tearing pain through her sphincter that stabbed her brain. And yet, with her pussy still being teased... all she craved was release.
"Aaaaaah...! Haaaah...!" I want to cum. I want it so bad it hurts. I've held out this long—haven't I done well? Let me cum now! I need it... I need it... I need to cum...
"Gguuuuh...!" If this were just some lovers' SM play... she'd have surrendered, sobbing and begging for climax. But owner and slave. Trainer and female livestock. In this blatant hierarchy, even speaking was a risk.
"Gguuuuh...!" The endless hell seemed like it would go on forever... until suddenly, it stopped. The Manager's hand lifted from her pussy. About five seconds. An awkward silence hung in the air.
Panting raggedly to calm herself, Heo Seong-ah bit her lip in dread of the pleasure to come.
"Livestock Number B62."
"Hngk!" Contrary to her fear of another touch, his voice shattered the silence, startling her into a hiccup.
"Livestock Number B62."
"Y-yes...!"
"You've held out well so far, so I'll give you one choice."
"A choice...?"
Suddenly? Every time he dropped words like that out of nowhere, something ominous followed.
"Do you remember the reward we agreed on at the start?"
"Uh...?" After expanding her rear... if she expelled the anal plug herself, he'd skip the next urethra modification. That groundbreaking offer.
"Y-yes... You said no urethra modification..."
"Correct. Good memory."
With a smirk, the Manager cleared his throat and continued.
"As a special bonus to skipping that initial urethra mod, I'll add one more choice."
"Yes..."
"Hmmm... One orgasm. How about it?"
"Y-yes...?"
It was a shocking, utterly revolutionary proposal. Letting her cum was exactly what she craved most right now... but enduring urethra modification? She'd die first. Just like her ass, soaked in aphrodisiac, she'd become a pervert climaxing every time she peed? Horrifying even to imagine.
"Answer quickly. Skip the urethra mod, or cum? Honestly, no need to agonize over it, right?"
He could read her inner turmoil plain as day. Her mind a mess from the pent-up need, yet she kept hesitating—it was starting to annoy him.
"Fine. No answer? Then forget I said it..."
"N-no... wait...!"
"Haa, I'll give you three seconds. Answer within."
"Guhk..."
Urethra mod was unthinkable. But giving up this sweet release to end the frustrating ache? Impossible. She hated the mod... but craved orgasm...
"Guh... Hng..."
"Three seconds... three seconds... one second..."
"I-I'll speak!"
"Yes. Answer quickly."
Now she had to voice her thoughts. Heo Seong-ah swallowed hard, face crumpling as she replied in a reluctant whine.
"I... I want to cum..."
"Understood. Wise choice."
"Hng..."
A shortsighted decision, thinking only of the moment, not the future. The Manager grabbed her hair, yanking her vacant, dazed head up.
"Agh!"
"What are you doing? Hurry into position and finish expelling the anal plug. Don't you want to cum?"
"I-I'll do it... hng..."
Deep despair at the thought of her impending mod warred with efforts not to regret her choice, mingled with anticipation for the climax ahead. All that built-up pleasure... its release would be unforgettable, the peak of her life, she was sure.
"Gguuuuuh...!" Heo Seong-ah strained at her sphincter again. Ignoring the colon pain, pussy dripping, she pushed to expel the plug—but it wouldn't budge.
"Gguuuuaaaang..." Exhausted, she slumped forward with a sigh. A sharp smack on her ass jolted her straight; steeling herself once more, she bore down.
"Gguuuung!! Guh...!" Like defecating, she pushed with all her might. Her anal wrinkles writhed in spasms, inching the plug out... but never visibly so.
"Grroooaaah..." Her body slumped limp, legs quaking as she bowed her head.
Smack—
"Eek!"
Fire on her ass again.
"B62, hurry up. Haa, no time limit, so you're getting sloppy?"
"S-sorry..."
"Haa, fine. Won't work. Five minutes from now. Fail to expel it, and the offer's off."
"N-no way... guhk...!"
No time for despair, begging, or protest. Single-minded, she strained her sphincter for the five-minute goal.
"Gguuuuung...!!"
Her face flushed crimson, body shuddering violently. The harder she pushed, the more her colon screamed like it might tear. Pleasure after pain, she thought, holding her breath and bearing down...
"Nnghaaaa..." But the plug didn't move. Of course not—the Manager gripped it firmly.
"B62, hurry. Three minutes left."
"Grrooh..."
Clueless to the truth, Heo Seong-ah panicked at his prods, pushing relentlessly without rest.
"Gguuuuung!!"
No matter how long, it stayed put. The five minutes flew by; with a nonchalant flick, he seized her hair.
"Guh...!"
"Time's up. Haa, with such weak anal muscles, how can you become fine female livestock? Quite disappointing, B62."
"S-sorry... hng..."
From the man who'd wrecked her sphincter... the injustice stung, tears welling up.
"Enough. No orgasm as promised, on to the next room... but I'll give one more chance. Special mercy for an ignorant cow."
"Yes?"
The first and last. Leniency for the clueless female livestock.
