Come Here and Suck It
Originally, a true loser is someone who sucks at kkil-kkil-ppa-ppa—that social banter summed up in a single phrase. But really, it's social intelligence. Acting appropriately based on context sounds easy, but it actually requires both acquired social training and innate empathy. In short, without the ability to read the room, you end up like Cheol-gyu Lee right now—frozen stiff, blurting out a dumb "...Huh?"
Even drunk and wobbling, Yeon-woo Lee felt pathetic pity for her dim-witted cousin.
"Ha... you're a pervert and a fucking retard? You don't remember me slapping you this morning?"
"Ah...?"
In truth, it was a bit unfair to Cheol-gyu. He'd come home fine, washed his feet, and was getting ready for bed when his cousin—reeking of booze—suddenly stripped and asked how much he'd pay. Even now, all his nerves were locked on her upper body: she'd tossed her cardigan and blouse, leaving just her bra. Despite being a massive 70G cup, her breasts strained against it, soft yet heavy, threatening to overflow... But it wasn't just her tits—the blindingly white, smooth skin, the elegant curve of her collarbone, the pale, slender neck above it. Every inch was a sight he couldn't tear his eyes from.
So of course he couldn't think straight or even process her words properly.
"...Fuck, are you doing this on purpose? Trying to make me say it?"
He really hadn't caught it. But then lightning struck Cheol-gyu's brain as his sluggish neurons finally connected the dots between "this morning" and the current situation.
"W-Wait... you mean this morning, that... thing?"
"...Ha. Yeah, dumbass."
"..."
And Yeon-woo—who had to offer a handjob to the cousin she despised, for money—felt utterly humiliated, her words tumbling out in a rush.
"...If I do it like last time... you'll really shut your mouth?"
"Y-Yeah... of course..."
"You didn't keep your promise at the OP either."
"I-I didn't promise anything."
"That community site... you posted it, didn't you?"
"..."
"Ha... you fucking cousin..."
Cheol-gyu stayed silent, but Yeon-woo was certain. This loser had posted her promo account on that site.
This otaku fuck... no, otakus are more dangerous because they lack any sense of reality.
A chill hit her—the fear that this clueless dork might actually spill her info and secrets to someone. Plus, with the booze numbing her judgment... she figured satisfying his lust a bit would settle it.
...But doing it for free with this guy pissed her off too much. Might as well get paid.
===== Yeon-woo was pissed. Yielding to blackmail and showing weakness? Infuriating. That it was to monkey-faced Cheol-gyu? Double infuriating. And her proactively demanding cash like some whore? Utterly humiliating.
...Though she was a whore who sold her body.
"S-So... tw-twenty... twenty thousand won... how 'bout that?"
Cheol-gyu, timidly testing the waters with 200,000 won, only annoyed her more.
"Twenty? Are you insane?"
"Th-Then?"
"...Five hundred thousand."
"Gasp..."
Even for Cheol-gyu, who got generous pocket money, 500,000 was steep. She'd barked it sharply on purpose...
"...I-I'll pay."
"What? For real?"
Yeon-woo blinked in shock at his quick agreement. He'd pay that?
"B-But... in exchange... I wanna do it."
"...Do what?"
"...Sex. W-With you, sis..."
"Ha... fuck off, don't push it."
Of course.
"N-No?"
"Obviously not... I told you, I don't wanna fuck you. How many times do I have to say it?"
"..."
Cheol-gyu felt wronged. 500k was more than he paid at the OP. And he was already hard...
But forcing his rejecting sister? Even he, the coward, chickened out.
"Fine... th-then 300k for... like last time?"
"..."
"...O-Or... 350k..."
"...Ha. Fine."
Yeon-woo finally grumbled and sat on the bed. She shoved her awkwardly perched cousin aside.
"What? Lie down."
"Huh? Oh..."
Cheol-gyu flopped back limply. Yeon-woo bit her lip hard, her jaw trembling with shame and reluctance... but she grabbed his trunk briefs.
"S-Sis... I'll do it."
"Hurry up. I wanna finish and sleep."
"Mm..."
He yanked his trunks to his thighs. Though his mind was a haze of frenzy, his cock had dutifully done its job.
Thwunk!—A massive meat club, absurdly huge on his small, scrawny frame. Uncircumcised, the foreskin half-peeled to reveal raw red glans like a dog's prick. Cheol-gyu's grotesque dick stood straight up at the ceiling.
Yeon-woo—ignoring his ugly mug—felt her gut twitch at the sight of that monster.
Fuck, it's huge... crazy bastard.
Was she ashamed of that momentary pull? Smack! She slapped his lower belly hard... Ptoo! Spat on her palm, then gripped the veiny shaft roughly.
"Hoo... feels good?"
"Uh..."
"Fucking pervert..."
"..."
Slap-slap-slap-slap... Her slender, long fingers clamped the hideous cock, jerking it roughly back and forth again. Shluuurk... shluuurk... shluuurk...
"Ngh...!"
The rough strokes peeled his foreskin back, then forward, the sensitive band sparking insane pleasure. He could cum from that alone... but it felt lacking.
And though he'd blackmailed her, her dominant pushiness irked him. Plus, wasn't this just repeating last time?
Grievances piled up, and Cheol-gyu shocked himself with bold action.
"Sis."
"...What?"
Grab. He seized her slim wrist. Even shorter, her strength was no match. Feeling that sparked courage.
"...I'll give you 500k."
"Fuck... I said no. I don't wanna fuck you."
Another harsh rejection bruised his pride, but he gritted his teeth.
"...Not that. Use your... m-mouth."
"What?"
"You jerked me last time... suck me this time."
"Crazy... no..."
"600k! 600k!"
His desperate shout made Yeon-woo slap a finger to her lips—shh!—panicking to shush her lunatic cousin.
"...Hey, nuts? Quiet. Everyone'll hear."
"...Y-You'll do it?"
"..."
Hating him or not... 600k for a blowjob? Tempting.
"...Where'd you get that kinda... whatever. You got it now?"
"C-Cash?"
"No?"
"I do!"
"I said quiet!"
This psycho. What if the neighbors heard? Seeing her anxious fussing, Cheol-gyu smirked triumphantly.
...She's more scared of getting caught doing this with me?
Made sense. Sure, he was the bullied son, she the praised niece—but he was Dad's blood, the homeowner's kid. If "trouble" hit, blood's thicker than water; she'd get kicked out over the scandal.
And if push came to shove, he'd expose her whoring. Terrifying.
It hit him: right now, she was the weak one. He held power. New desires surged, and he yanked her wrist, pulling her up.
"Wh-What?"
"Come here and suck it."
"..."
Sudden shift—his tone commanding, oppressive. Yeon-woo blinked in flustered shock at his "rebellion."
Cheol-gyu grabbed her pretty face with both hands, pressing his cock close.
"Uh..."

The massive cock's shadow loomed over her face. Gulp. Yeon-woo swallowed unconsciously.
"...Suck it quick. I said 600k, right? Yeah?"
"...O-Okay."
Strictly, she hadn't agreed yet... but weirdly, defying him felt impossible now.
Yeon-woo was weak to dominant males.
And for the first time... she was being devoured by a stronger Cheol-gyu.
=====
"...You really gonna suck?"
"Yeah... hurry."
"Haa..."
Is this right? Almost forcing a blowjob on this loser Cheol-gyu?
As Yeon-woo parted her lips hesitantly, complex emotions swirling—
"Haa... haa!"
Cheol-gyu panted roughly, thrusting his cock between her red lips.
Like a dog in heat, wildly aroused... forcing it in with brutal motion.
"Mmph!"
"S-Sis...! Y-Your mouth feels... so good..."
"Mmmph! Mmmf!"
Way different from a handjob! The handjob had been ecstatic, but demanding oral, forcing it in...
I've conquered sis's mouth-pussy...
A massive conquest rush hit him. And this position: handjob was passive, lying back. Now? Gripping her small head, fucking her mouth-pussy.
Plus, looming over her kneeling form—gazing down like a lowly slave. Perfect for the long-suppressed Cheol-gyu.
"Haa... haa... oral, sis."
Confidence surging, he yanked her head—cock still buried—forcing her along.
"Mmgh?!"
To the full-length mirror in the corner.
Yeon-woo had to watch—vividly—in the reflection: her vulgar self "servicing" her cousin.
