My Sister, the Outcast's Flesh Toilet
Min Jia: Biological Older Sister (Prestigious University Graduate, Former Major Corporation Employee)
"Mmph... Hngh...♡♡"
Min Jia was meticulously licking a penis.
The owner of that penis was none other than—
"Sister. Are you really going to lick it that half-heartedly?"
—her good-for-nothing biological younger brother.
"N-No, Jihun! I'll lick it harder! I'll suck my little brother's cock as hard as I can!!"
Terrified by her younger brother Jihun's words, Jia picked up the pace, her tongue moving even faster.
"Slurp! Shluuuck!!!♡♡♡"
Jia used her tongue to the absolute limit, meticulously teasing her brother's fleshy rod.
With a skillful fellatio honed through years of casual dating, Jia quickly aroused Jihun's cock.
It was what one might call the 'work of her ex-boyfriends.'
Ever since she entered a prestigious university in Seoul, Jia had gone through countless men.
Sometimes she dated seriously with her sights set on marrying up; sometimes it was just for fun; and sometimes, simply to get her pussy thoroughly drenched in cum, she used dating apps for one-night stands.
The number of men who had shoved themselves inside her pussy was easily in the double digits—no, depending on how one counted, it was probably closer to triple digits.
Now that the world had changed, she was despised as a 'loose whore.' She had lived a life so promiscuous that, under the current laws, she could have faced an 'honor killing.'
However, her wild days of sleeping around like a whore had not gone entirely to waste. Her precious 'experience' was now being fully utilized to satisfy her biological younger brother, Jihun—who was now both her Human Rights Guarantor and her master.
"Sister. Do you want to go earn some money again?"
Jihun looked down with dissatisfaction at his older sister, who was sucking his cock, as if something still displeased him.
"I'm sorry! I'm sorry! I'll suck my brother's cock so hard, so please, please!! Hic... I don't want to earn money anymore! I hate earning money!!"
At the words 'earn money,' Jia reacted as if a panic button had been pressed, thrashing and begging in absolute terror.
And for good reason—the superb sexual techniques she was currently using on her brother were not solely the work of her ex-boyfriends.
Between her arms, which she was desperately rubbing together in a begging gesture, her large breasts were visible.
Her breasts bore the clear marks of severe abuse; one side was bruised a dark blackish-blue, and one of her nipples had been violently torn off by something.
On her slightly more intact breast, several circular burn scars—unmistakably from cigarette burns—were deeply branded.
Cigarette burns were scattered across her arms and the backs of her hands as well. The worst area was her right forearm, where over a dozen cigarette burns were grotesquely clustered in a small space about half the size of a palm.
On top of that, several of her fingers had been broken and left to heal on their own, leaving them twisted in bizarre, unnatural angles, and a few of her fingernails had been ripped out and ruined.
These horrific scars were all thanks to Jihun, who had kindly carved out a brand-new career path for his older sister.
That new career was—
"Honestly, Sister, I think being a whore is your true calling."
—prostitution.
Jihun, as Jia's Human Rights Guarantor, held the legal right to exercise her human rights on her behalf.
Because of this, Jihun had forced Jia to quit her job at the major corporation and arranged for her to work in 'prostitution'—a job he deemed far more suitable for a woman.
After all, Jihun believed that a career at a major corporation was nothing but a luxury or a game of house for a mere bitch.
Naturally, the customers in this reversed world were not as gentle as those in the past. Assault and torture were daily occurrences.
Consequently, Jia had to submissively spread her legs and do everything in her power to avoid displeasing her clients. The advanced techniques she acquired through those grueling efforts were now being put to use whenever she served her brother.
"Ah... Ah... Th-Thank... Thank you... No, I don't want to be a whore... I hate being a whore..."
At Jihun's sudden praise, Jia lost her bearings once again and began to tremble hysterically.
The PTSD of extreme sexual torture flashed through her mind—
"Ah... No... No..."
—and her urethra helplessly gave way.
Dark yellow urine began to pool beneath Jia's thighs.
"Why the fuck does your piss smell like it's rotting?"
Due to extreme violence and exhaustion, Jia's urine was heavily concentrated, emitting a stench far worse than normal piss.
"Sister, did you drink fucking sewer water or something?"
Jihun slapped Jia on the head, thwack, thwack, with his palm.
"Fucking bitches... a degree from a good university is completely useless on you lot."
Smirking, he poked Jia's forehead repeatedly with his index finger.
"Huh? What's the point of wasting all that tuition money and getting a good job? You still can't get rid of your pathetic bitch instincts, you're too fucking stupid to understand simple words, and you can't even control your own bladder. Right?"
He kept poking her as he questioned her.
"Am I right? Don't you also wonder why a useless cunt like you even bothered getting a degree from a prestigious university?"
Jihun pressed her for an answer.
"Yes, you're right... For a cunt like me, a college degree... a career... it's all completely useless. That's why it's only right for me to live as a man's cum dumpster for the rest of my life."
Jia desperately squeezed out the exact answer she knew would satisfy Jihun.
It was an answer formulated from the 'cock data' she had accumulated after being raped by her younger brother countless times.
"See? That's my smart sister. At least you learn quickly when you're taught."
Jihun stroked Jia's hair with satisfaction.
At the same time, he slapped her cheeks, slap, slap, with his cock.
Was it the result of relentless physical and verbal gaslighting? Or was it simply relief that, at least for now, she wouldn't be subjected to pain?
Or had she actually begun to feel some twisted form of affection for her own brother?
Jia herself didn't know, but she let out a faint, submissive smile.
"What are you doing? Hurry up and suck it."
Jihun growled, tightening the leash of tension once more.
"Y-Yes! Gulp!♡♡"
Jia hurriedly clamped her mouth around Jihun's cock.
"Slurp... Nnh...♡♡"
Once again, she meticulously worked her tongue and teeth.
"Ha... seriously, why does my sister's mouth-pussy feel so fucking good?"
"Mmph... Hngh...♡♡♡♡"
Seemingly pleased by Jihun's praise, Jia worked her tongue and mouth even more aggressively.
As Jia's tongue skillfully cupped the base of his shaft and his glans pressed against her hard palate, a sharp, throbbing pleasure shot straight up Jihun's spine.
"Fuck, Sister, you're so damn good at sucking... ugh..."
Jihun gritted his teeth, holding back his ejaculation.
"Slurp... Shluuuck...♡♡♡♡"
Elated by Jihun's praise, Jia even managed to curl the corners of her lips into a slight smile while keeping his cock in her mouth.
"..."
Jihun chuckled, stroking the crown of his sister's head as she knelt meekly, entirely absorbed in the blowjob.
Suddenly, Jihun recalled a story about a woman who fell in love with her rapist.
The purpose of the womb is reproduction.
Since a woman's purpose is merely to carry a womb around, her true essence is the womb itself.
Therefore, by accepting semen into her womb, a woman fulfills the very reason for her existence.
Thus, women are creatures who will accept anyone as their husband, be it a rapist or anyone else, as long as they shove a cock inside them.
Perhaps his sister had been pounded by him so much that she had actually fallen in love with him.
Reaching this conclusion, Jihun—
"Sister, do you love my cock that much?"
—suddenly wanted to confirm if his theory was true.
"Mmph... Yes... I love it..."
Jia pulled her lips away from his cock, which she had been greedily sucking, and looked up at Jihun, answering slurringly.
Seeing Jia's pathetic, submissive state, Jihun suddenly felt mischievous.
"Who the fuck told you to stop?"
"I'm sorry! I'll close it! I'll keep my retarded mouth shut!!"
Terrified once more, Jia rubbed her hands together frantically like a fly begging for its life.
"You retarded bitch, then shut your fucking mouth and keep sucking."
Jihun grabbed Jia's trembling, terror-stricken head and slammed it down against his crotch.
Her hair was tied back in a ponytail, making it a perfect 'handle.'
"Mmph?! Hngh?!!♡♡"
Jia's mouth was stuffed to the absolute limit with Jihun's cock.
Her jaw was stretched to its breaking point, creaking on the verge of dislocation.
"Gagh?! Ack?! G-Gaghh?!!♡♡♡♡"
The thick shaft blocked her esophagus and trachea, cutting off her air, but driven by sheer terror, Jia instinctively bobbed her head back and forth.
As she frantically bobbed her head up and down, sucking her brother's cock for dear life, she looked exactly like a chicken pecking at feed.
"Fuuck—why is my sister so damn hot? Seriously, I wonder if Mom gave birth to you just so you could be my living fleshlight—"
Jihun showered her with twisted praise as he gripped her hair.
And then—
"Pfft?!?!♡♡"
"If you're a fleshlight, act like one and clamp down harder with that mouth-pussy, you fucking bitch."
He shoved her head even harder against his crotch.
With his cock stuffed down her throat, Jia's face repeatedly smashed against Jihun's pubic bone and lower abdomen, distorting her features.
"Khh-pff?! Khh-ggh?!♡♡♡♡"
With a wet, squelching sound, Jihun's pre-cum began to leak thickly from Jia's nose.
Unable to breathe, her eyes rolled back.
Deprived of oxygen, her entire body began to convulse violently.
"Ghh-pff?! Kh-ggh?!♡♡"
Yet Jihun, fully aroused now, did not stop.
Desperate for air, Jia tried to inhale.
But mercilessly, only pre-cum and saliva flowed down her windpipe, burning her lungs.
"Mmph-ggh?!?! Khh-gghh?!?!?♡♡"
Her diaphragm spasmed violently in an attempt to expel the foreign fluid, but with his cock completely sealing her airway, nothing could escape.
"Kh-gghh?! Mmph?!"
The fluid continued to seep into her lungs, compounding her agony.
Jia's face turned a dark, flushed crimson.
Tears and pre-cum-laden snot streamed down her chin. Her fingers, twisted and deformed, clawed uselessly at the empty air.
Just as she was on the verge of passing out—
"Ah... Sister... Sister!!"
Reaching his climax, Jihun slammed his pelvis hard against Jia's face and unleashed a torrent of semen.
"Mmph... Ghk?!?!♡♡"
The thick semen flooded her stomach and windpipe.
Spasming in her esophagus, the semen backed up into her nasal cavity, filling her sinuses and dripping thickly from her nose like mucus.
"Sister... your mouth-pussy is so fucking good, goddamn..."
After finishing his ejaculation with a sigh of satisfaction, Jihun—
"Mmph-gghh?!?!?♡♡"
—pissed straight into Jia's mouth.
Her mouth was no longer even a mouth-pussy; it was now a literal toilet.
Jihun's yellow urine overflowed from her stomach, bubbling out of her nose.
"Phew..."
Exhausted, Jihun finally let go of Jia's hair.
Jia's limbs convulsed on the floor for a moment before—
"Gasp."
—she collapsed limply into the puddle that had pooled beneath her thighs.
A foul mixture of her own urine, Jihun's urine, semen, snot, and tears assaulted her nose.
And then—
"HURK!!!"
Jia began to vomit.
"BLECH!! Ghhhk?!?!"
Her back spasmed as she added her own vomit to the puddle of bodily fluids.
"GAAAHH!! Ghhhk!!"
She writhed on the floor, making wet, disgusting retching sounds, but Jihun didn't even think of patting her back. He simply stared down at her with a mocking sneer.
"Pathetic bitch."
"HURK!! Ghk!!"
After retching a few more times—
"Ugh... ghhk..."
—Jia collapsed face-down, her chest and face pressing directly into the puddle of her own vomit and waste.
"Ghk... ugh..."
Her cheek rubbed against the thick, slimy mess. With every shallow breath she took, bubbles of semen and bodily fluids formed and popped against her skin.
With her eyes rolled back, Jia's mind drifted back into the past.
