Cousin Sis is a Morning Sex Toy
There's a term called sex processing. It's shorthand for "sexual desire processing," mostly used in Japanese porn or manga, and it specifically refers to using a woman purely as a tool to relieve sexual urges.
Yeon-woo Lee was experiencing firsthand just how violent that concept becomes when applied not to some fictional medium, but to a real woman.
"Hurry up and drop those pants, sis."
"..."
Just because he's horny first thing in the morning, in this house where the whole family is up and about... he's ordering her to strip for sex processing.
Issuing such a command without a second thought. Not seeing her as a person at all, but like a toy with no purpose beyond fucking.
Overwhelmed by the shame, she bites her lip in a feeble show of resistance... but Yeon-woo has no choice. She has to take off her pants.
And inside her dolphin shorts... nothing. A no-panty crotch. Not a single hair, smooth and bald like a little girl's, her deep pussy slit exposed without any obstruction.
Surprisingly, she'd been going commando since breakfast—no, since last night after fucking Cheol-gyu. Straight through without panties.
It's not his first time seeing sis's pussy, but that obscene sight still makes his heart race like it's brand new. Cheol-gyu's cock, already rock-hard from the morning surge, swells even bigger.
"...As ordered... no panties."
The command he'd given her after fucking till dawn. No more panties from now on. Not just skipping them once—it was permanent. Without permission, her default state is no panties.
For Yeon-woo, panties have become a luxury item now, something she can only wear if her master allows it.
Having built up his perversion from endless porn as a total loner virgin, Cheol-gyu finds it easy to issue such abnormal orders in this twisted situation.
"Good girl. My sis is such an obedient slut. Makes sense for a pro whore, huh? Heh heh."
"..."
"How's it feel? Being a sex slave ain't so bad, right? Be honest... you look like you're enjoying it. You cum so hard every time we fuck."
Praise from a guy she hates only brings humiliation. Her chin trembles with shame, teeth digging deeper into her lip, but to Cheol-gyu, that reaction is a reward.
Grinning wickedly, he wags his finger arrogantly, commanding his cousin sister without a care.
"Now. Hands on the desk, turn around. Stick out that fat sow ass."
"...Okay."
So obvious what he wants. Wearing just a t-shirt, bottom half completely naked, Yeon-woo turns her back to Cheol-gyu, bends at the waist, and thrusts her ass out.

Shamefully, her uncovered natural pussy and plump ass cheeks part slightly, exposing even the wrinkled rosebud of her anus in stark detail. Just like at the gyno for a pussy or anal exam.
If it were for a lover, maybe—but being forced into this lewd pose by the cousin she despises most, blackmailed into it... A sigh, irritation, nausea, and shame well up inside, but she has to hold it in.
"Hoo... hoo... Pink and pretty pussy..."
Whether Yeon-woo feels humiliated or not, Cheol-gyu strokes his throbbing morning wood and shoves his face right up to his naked cousin's crotch, nose practically buried.
"Sniff... sniff sniff..."
"...Ugh."
His face way too close to her lower half. His hot, excited breaths blasting her pussy make her squirm—one part shame, one part that ticklish itch deep in her gut.
"What? Hate having a loser like me sniff your pussy stink?"
"...N-no... Master..."
"Getting the hang of it, huh? Even calling me master on your own?"
"..."
Yeon-woo's face twists like she's chewing shit, but Cheol-gyu lets it slide. Why? Because he prefers it when sis shows she hates him, finds him disgusting, feels humiliated—over her acting like a mindless doll or fake lover.
I don't get it myself... but forcing my sis who hates me? It gets me so fucking hard.
Especially that face: hating it but cumming uncontrollably on his huge cock, expression crumpling in humiliated disappointment at her traitorous body. While getting incest-raped by her most hated cousin.
To Cheol-gyu, that's the ultimate turn-on. Maybe like ducklings imprinting on the first thing they see—his first experience being violent degradation twisted his sexuality that way.
Anyway, he doesn't hold back, unleashing his filthy urges freely.
"Fuckin' bubble butt... so goddamn huge. You slut."
Smack.
"Hngk...?!"
With the family in the living room, he can't slap too loud, but he targets a more sensitive spot: her plump, protruding labia majora. Like smacking a guy's glans or balls.
The stinging pain makes her sleek body writhe on instinct. Ah... fuck yeah... beating a woman's ass, tits, pussy whenever I want. And she's my cousin slut who loves it.
Excited, Cheol-gyu grabs her ass cheeks roughly, kneading them while verbally degrading her even harsher.
"Like it? Huh? Getting your pussy lips smacked feels good, right? You arrogant whore."
"...Y-yes... I like it..."
"Weak answer. Make it dirtier, sluttier. You're a born cumrag, you know this shit. Drop the innocent act, you whore."
"..."
"What? No answer? What do you say when master smacks your ass?"
"...Th-thank you... for beating my worthless pussy... as much as you want..."
Her face screams she doesn't mean it, but Cheol-gyu leaves it. Like before, that bit of defiance makes it hotter. Makes the forced rape feel real...
"Good. Now shake that ass and beg. Beg me to fuck you."
"...Huh?"
She missed it, focus slipping for a second. But Cheol-gyu doesn't wait, delivering punishment without mercy.
"Not listening, you bitch? Pay attention."
Penalty for zoning out: not a slap this time—three fingers shoved straight into her pussy without warning.
Three thick digits stuffing her fragile hole, stretching it to tearing pain.
"Heek...?! It h-hurts...!"
"Shh. You sow slut. What if we get caught 'cause of you? Shut your mouth."
"Hngt... ngh."
Cheol-gyu's demands are escalating beyond day one. A perfect gauge of how low Yeon-woo's status has fallen. Sow slut, cumrag, whore... now treating her openly like the lowest sex toy.
Her vision blacks out. But what can she do? Reporting him means confessing to Jin-woo, Uncle, Dad what she's endured, what she's done... worse than death.
So even as he degrades her more, she grits her teeth, plays along... shaking her big, pretty sow ass and spouting lies.
"Ngh... my w-worthless... p-pussy... fuck it... as hard as you want..."
"Puhaha... epic."
Click.
Camera shutter. Glancing back, he's filming her—bent over the desk, ass out, who knows how long.
"...Y-you recorded from the start?"
"Duh. Got a problem? Remember the contract? I can film you anytime."
"...O-okay... just asking..."
This humiliating scene captured on video...
Ah... I hate this so much...
But no choice now. She endures as his sex doll, holding out for possible future freedom.
=====
"Hoo... hoo... Want me to fuck you?"
"...Please fuck me, Master..."
"Why? You love my cock that much?"
"...Y-yes... Master's cock... so big and thick... I love it..."
Just parroting what he wants. Obvious for a basement-jerking loser virgin.
But even reciting those clichés, rage boils in Yeon-woo. Because... it's partly true. That's what she hates most.
She definitely hates Cheol-gyu. More than before. Not just ugly loser vibes—now blackmailing her into sex slave treatment.
But separate from her feelings, the moment his cock slithers in like a giant snake, filling her pussy tight... her walls stretched taut, smoothing out her folds...
"Ngh..."
Her body shudders, pleasure hitting against her will. That goblin-mismatched monster cock—thick, long, grotesque—makes her twitch instinctively.
"Haht... mmph... mmmph..."
Even muffling herself to avoid Uncle or Jin-woo hearing... she can't contain the moans.
She hates it. Hates it so much.
But...
"Hngph... mmph... mph... mmmph..."
"Shh!... Control your moans, you fuckin' sow grunting like that."
"Mmmph..."
Being called a sow insultingly, yet shivering with electric thrills each time his banana cock spears through her... unavoidable.
Fuck... I hate it... hate cumming from this bastard raping me...!
Suppressing moans? Futile against the squelch, squelch... squelch... For someone virgin till recently, his huge, veiny horror scrapes every inch on every thrust, forcing animalistic groans.
"Fuck... seriously. We'll both get fucked if caught. Hold it in."
Getting bitched at by her rapist mid-fuck. Her pride hits rock bottom.
"...O-okay..."
"Hoo. Try holding it."
"..."
Pounding resumes. But...
"Hngt... mmph... mph!!"
"Fuck... I said quiet..."
Thump thump thump—his glans battering her womb... impossible to stifle.
Finally pissed, Cheol-gyu snaps,
"Shit... fine. Bite this."
He shoves something into his cousin's mouth by force.
"...Mmph?!"
It was...
