10 - Shameless Vulgar Pleading
Having crammed Rienna's head full of sexual knowledge overflowing with his own twisted tastes, Han Jin-seong said excitedly.
"Now try it again. Super trashy and slutty. If I like it, I'll fuck you as a reward."
"…!"
Every word he'd taught her hit Rienna like a hammer to the skull. It felt like her world of purity and abstinence was being buried under a mountain of filth. She had to spit out these vulgar words and phrases she'd never even dreamed of hearing, let alone saying, with her own mouth.
Her body couldn't refuse. The scorching presence buried deep in her ass, unmoving and filling her completely, pierced far deeper than those filthy words seeping into her brain. Stopping now... was simply unimaginable. Losing this sensation, this pleasure, felt worse than death.
After dozens, hundreds of fleeting hesitations...
Rienna's trembling lips finally parted, slowly... of her own will. Her tear-streaked cheeks twitched briefly.
"Haa...♥ M-Master...♥ This... this filthy elf bitch's dirty... dirty shithole pussy...! Shove your massive cock in it, please...!"
The moment the words escaped, Rienna's face burned crimson beyond control. She couldn't believe it. A noble elf like her, spewing such depraved filth from her own lips.
But her ass was brutally honest. As she spoke, it instinctively pushed back, trying to swallow the cock inside even deeper.
Squiiiish...♥
"Hngh...♥ Th-This lewd elf's shithole pussy... loves Master's cock so much...♥ So please... stretch this trashy asshole wider... turn it into Master's personal meat toilet onahole...♥♥!"
Rienna's beautiful, melodic voice gradually dripped with coquettish sweetness and seduction. The tears of shame threatening to burst now glistened with desperate pleas for his cock. Emotions like humiliation were swept away without a trace before the massive wave of pleasure.
"F-Fill me... stuff me full... cum buckets...♥ Fill this bitch's shithole pussy to the brim...♥ Turn it into Master's exclusive cum-dump toilet...♥ Make a total mess of it...♥ Master...♥!"
With every vulgar word she uttered, it felt like the strings of her rationality in her mind were pulled taut—then snap—snapping one by one. Her brain seemed to be pickling in depravity and trashiness, a horrifying sensation.
Rienna shattered the last chains holding her faint hesitation. Now, only the instincts of a bitch craving her Master's cock remained, her hips swaying seductively.

Han Jin-seong grinned in satisfaction upon hearing that. She'd reached a level worth teaching.
"Good girl. Now apply it. Be even sluttier with the coquetry! This is praise for what you just did."
As a reward, he thrust his cock up once, teasing the end of her rectum tantalizingly.
Paang♥!
"Haaang...♥!"
Her body convulsed like she'd been electrocuted from that single piston thrust right after her words. A single drop of dew falling into a parched desert—it didn't quench the thirst; it only ignited a fiercer one. A sweet, cruel praise that made her crave even more.
"Haa... ngh...♥ Th-Thank... you...♥"
Rienna's ass wiggled on its own from the praise. Sweat trickling down her back made her pleasure-soaked body glisten even more.
'Apply it... even trashier...'
Her mind raced desperately. The brain that once plotted only how to kill humans more cruelly, torture them more viciously... now frantically pieced together the vulgar words like a puzzle to please him. No, her Master. She wanted to make him happy. To savor this addictive pleasure to the end. That primal desire opened her mouth.
"Maaaster...♥ Look at this lewd elf's plump, jiggly ass...♥ It's made to be tamed by her beloved Master...♥"
Her voice was thicker, more lascivious than before. Genuine coquetry aimed at her male—her Master. Petty feelings like shame had been cast aside long ago. Her mind was now filled only with thoughts of how to please him more.
"Ngh...♥ Noble elf Rienna... is gone now...♥ All that's left here is Master's cock sleeve, a shithole desperate to be stretched... Master's exclusive bitch toilet onahole...♥ Fill this trashy shithole pussy with Master's baby batter...♥ Warm up Rienna's filthy hole...♥!"
As her words grew more provocative, Rienna instinctively shook her ass side to side. Like a puppy wagging its tail for attention. The unmoving cock inside twitched faintly with every sway, drawing involuntary moans from her.
"Master's cock is so huge...♥ My shithole's getting all loose...♥ But that's why I love it more...♥! Ram it in however you want, pound it, wreck this elf meat toilet onahole like a used rag...♥ I'll live as Master's cum-dump toilet forever...♥ Right...? Hnngh♥"
Excited by the trashiness of her own words, fresh pussy juice dribbled from Rienna's slit once more.
"Oh, nice. You're getting good. Keep up the coquetry. One coquettish plea, one piston thrust. Got it?"
Satisfied with her performance, Han Jin-seong rewarded Rienna with three piston thrusts.
Paaang♥! Paaang♥! Paaang♥!
"Heek♥?! Oook♥ Ohoook♥…!!"
True to his word, three brutal pistons impaled her shithole mercilessly. The fierce pleasure storming back into her halted body drew a scream-like moan from Rienna.
'Hngh♥ This feeling...♥ My brain's melting from this sensation♥'
One, two, three. Exactly three impacts later, the cock stopped again, as if by magic. In the wake of the storm's claws, only a more vicious thirst remained.
Rienna's vision spun. More, more, more! Her brain lost reason, craving only pleasure. Don't stop. Never stop!
"M-Master♥! Haaah...♥ Th-Thank you...♥"
Panting to catch her breath, Rienna desperately opened her mouth again. One plea, one thrust. The deal was simple enough for a child to grasp.
"This trashy elf bitch... ngh...♥ loves Master's cock so much...♥ Cock goooood♥ Long live cock♥! I wanna get pounded till my shithole's worn out and shit leaks nonstop...♥!!"
Paaang♥!
"Hiyaang...♥!"
The merciful piston hit right after her words, knocking her to the brink of climax again. Her whole body shivered with the sweet sensation.
'Ah...!'
Rienna got it now. How to keep the pleasure going.
"I-I'm... Master's living elf onahole...♥ My shithole's Master's cock-milk exclusive shithole pussy anytime he wants...♥ Kyaaang♥!"
Paaang♥!
"Aahngh...♥! P-Please... harder...♥! Mold this elf bitch's shithole pussy into Master's cock shape forever...♥!!"
Paaang♥!
"Hoooook♥…! M-My ass... every time it slaps against Master's hips...♥ Feels so gooood...♥ Spank this trashy oversized ass black and blue while you fuck it...♥! I'm Master's onahole... so it's fine...♥! Fuck me till my womb crushes...♥ Play with me however you want...♥!!"
Paaang♥! Paaang♥!
This time two in a row. The impacts slamming like rewards made her waist buck and a scream erupt. She understood perfectly now. The trashier and lewder the words, the more actively she shook and coaxed, the bigger the reward from Master.
Rienna's clear green eyes clouded over. Like a drugged addict or a broken recorder, she spewed every vulgar word she'd learned or imagined. Desperate struggles to earn even one more thrust.
"Aheuk♥ M-Master...! Fill this elf sow's shithole... hngh♥ with Master's cock milk...♥!"
Paaang♥!
"Hyeek...♥!! Yes! More! Harder...! Make this pathetic shithole a dumb hole that feels nothing but Master's cum...♥! Take responsibility...♥ Use this rag-doll shithole-tank elf meat toilet forever...♥!!"
Paaang♥! Paaang♥! Paaaang♥!
Deeper and fiercer impacts than before. Fireworks exploded in her mind. Eyes rolling from the reward, Rienna dragged out the crudest, lewdest words she'd ever known or conjured.
"My womb...♥ My baby room's quivering zzuk♥ zzuk♥ wanting to taste Master's cock...♥! Rienna... wants to be Master's cum-receptacle onahole...♥ Forever... forever this shithole pussy is Master's... no one but Master can use this cock-exclusive cum-dump toilet...♥! Oook... nghoook...♥!!"
Pang♥! Pang♥! Paaaang♥!
"M-My name... isn't Rienna anymore...♥! I'm Master's cocksleeve, Master's cock warmer case...♥ No need for the World Tree's given name anymore...♥!!"
Did that last line hit the spot? Unlike before, Han Jin-seong slammed his hips down with full force, ravaging her rectum and womb ferociously, determined to finish her off.
Paaaang♥! Paaaang♥! Paaaang♥!
The piston barrage as reward flashed before her eyes, and finally, the unreachable tsunami of climax engulfed her body.
"O... oh♥! Hoooh...♥! Cumming♥! Cumming from my shithole♥ Shithole pussy cumming♥♥!!!"
Her anal muscles spasmed uncontrollably, clamping down hard on the cock inside. Her whole body shuddered as her pussy squirted hot juices like a fountain again—psshuuut♥.
Lost in the afterglow of her intense anal-womb double climax, her eyes lost focus, utterly broken.
"Haa... hngh...♥ S-So good... my shithole inside... so hot... Master...♥"
Her exhausted body slumped onto the bed. Bound as she was, her raised ass didn't fully drop, but she panted, basking in the pleasure's echoes.
Satisfied at this point, Han Jin-seong decided to unleash his pent-up ejaculation.
"Hoo... Gonna cum now, so take every drop without spilling...!"
Paang—♥!!!
"Haaaang—♥?!"
Her body, still twitching faintly from climax, froze stiff. The halted cock suddenly plunged root-deep with pulsing throbs, then a whole new heat erupted toward her deepest depths.
Bluuurt— bluuuurt—!
Like compressed lava bursting forth, thick, slimy semen surged into her rectal walls with overwhelming force. The sheer volume filled her empty rectum instantly, the pressure drawing a short scream from her lips.
"Ah... aaah...! Wh-What... this... so hot...♥! My belly... my belly...!"
Unlike last time, Han Jin-seong didn't hold back. Determined to dump as much as he truly wanted, he pissed out his cum like a firehose, cock throbbing massively.
With Vitality at 12 (Transcendent), his cock casually spewed thick globs nonstop from the tip—blurt- blurt-.
His cock didn't tire. Transcendent stamina meant he could fill a bathtub in one go, an overwhelming, violent ejaculation.
"Haa... fucking refreshing... Hey, snap out of it. We're not done yet."
"Hngk...♥"
As her rectum swelled beyond capacity, the hot torrent forced its way deeper, into uncharted territory. It pried open the S-curved colon entrance, flooding deep into her guts.
Gluuurb- gluuurb- Odd gurgles echoed inside as her cold innards filled with hot fluid, a bizarre sensation stimulating her whole body.
"Haa... ahng...♥ My belly feels weird... Master's cum... filling my insides...♥"
Against her will, her lower belly began to bulge faintly. Like a snake slithering up her guts—an obscene, eerie feeling. Her upper body twisted involuntarily, sobbing moans escaping.
"Haaa...♥ Weird... my... belly... hngkkk...♥!!"
The thick white sludge filling her guts weighed heavily on her organs, tormenting her with a constant foreign presence. Her belly ballooned like she was pregnant from the nonstop cum-vomiting mega-cock. Face-down ass-up on the bed amplified the pressure.
But that fullness brought a vicious pleasure unlike climax—a branding of ownership and submission.
"Haaa...♥ Ah... no... my insides... Master's baby batter...♥ So full...♥ So full...♥"
Her drained body began shuddering again.
"Damn... anyone'd think you're pregnant. But we're not done?"
"Eh...? Hngk...♥?!"
Her sinking consciousness was yanked awake by the alien sensation. The fading throbs reignited fiercer than before, surging more hot cum.
The brief rest let her colon relax, only for a new semen wave to crash over it, shaking her body helplessly again.
"N... hngp... stop... no more...♥"
Rienna's pitiful moans didn't reach him—he wasn't listening anyway. The white flood rising to her colon's end now pushed relentlessly toward the forbidden beyond.
Her belly went beyond mere bloating, mixing unpleasant fullness with forced stuffing into a weird pleasure.
Gluuurb—♥ gluuuurb—♥
"Nggh... haat... uup...♥!"
Gurgles like live creatures wriggling in her belly echoed. The heavy fullness spread from lower abdomen to solar plexus. The cum flow had conquered below and reached her stomach.
"Kghk... ngh... uuk...♥!"
As semen filled her stomach, her body retched instinctively. The discomfort and alien feel of hot, sticky cum instead of food. But even that unease turned to subtle pleasure via the erotic tattoo, teasing her lewdly.
Her stomach swelling taut with Han Jin-seong's essence. An incomprehensible horror even for an elf—she felt awe and fear toward his impossible cum volume.
"Hooo...♥ Haa...♥ Please... enough... M-Master...♥!"
Finally, with her stomach full, the semen refluxed up her esophagus. A sticky, musky semen stench welled from her chest—terrifying yet utterly obscene.
"Hngp... uup... haa... up... oek...♥! Ueeek...♥!!"
Her blocked throat opened, and thick white globs gushed from her small mouth.
Cum starting from her shithole, refluxing through her guts, piercing her body to spill from her mouth.
"Haa... yeah... this is it. Haven't done a full cum piercing in ages—feels good. Hoo... good hole."
"Uek...♥ Hngp...♥ Kuek...♥!"
Each vomit of cum from her mouth pooled in the bedsheet's depression. Drowning in semen, Rienna couldn't think anymore. Her cum-smeared face and hair reeked disgustingly.
"………♥"
Her vision whited out, all senses fading into the distance. Only when her entire body was semen-pickled did Rienna finally let go of consciousness.
