Jealous Sister's Unforgiving Rampage
Seojun's perspective
"No panties...?"
"I forgot..."
Her face paled in horror.
"What do I do? I don't have anything to change into."
She stomped her feet, flustered and at a loss. The panties lay shredded on the floor, utterly ruined and unwearable.
"Hoo..."
In the end, he rummaged through his bag. Just in case, he'd packed spare underwear that morning—men's boxers. Carrying women's panties around was embarrassing. Plus, ventilation was key. Her body, virgin until recently, would be sore all day otherwise.
"Wear these at least."
"Huh? These are your boxers."
"You wanna go commando to class?"
After hesitating, she snatched them away. Her legs wobbled, and she steadied herself on his shoulder as she stood unsteadily.
"Tch... These are fucking huge."
Grumbling irritably, she slipped both legs in. But the moment the fabric clung to her skin—
Squelch.
Did her pussy sense it? Or her nose? Despite her anger, a lewd moan escaped her.
"Nngh..."
He couldn't help but chuckle. Typical. Her mouth always bitched and moaned, but her body was brutally honest.
Seo-ah's perspective
Click. She fiddled with the waistband, pretending nonchalance. She swallowed the thrill bubbling inside her.
Too good...
Baggy men's boxers. Thick, vibrating musk. It felt like a mini Seojun was rubbing her directly from inside the fabric.
"Heh, heh. Hahaha."
Mini Seojun. Must be adorable. Maybe shrink him with magic next time? A sinister grin crept across her face unbidden.
"Why're you grinning like a creep? Thinking something weird again, huh?"
Seojun called her out sharply.
"I'm not! You're the one with filthy thoughts, making the whole world look dirty."
She snapped back with feigned irritation. But her womb betrayed her.
Slosh. Squish.
It couldn't hide the semen sloshing deep inside. Her belly stuffed full of her little brother's warmth. A satisfaction like owning the world.
Sniff— haa. Snort.
She ducked her head instinctively. Inhaling the rising scent deeply. It was ecstasy enough to bury her nose and huff like a fiend.
Seojun's in my womb, and now in my panties too...
"Heh, heh, hehehe."
Ah, that creepy laugh slipped out again.
"What the hell's wrong with you since earlier..."
Seojun backed away warily, looking grossed out.
"Hurry and mop the floor. Before the smell sets."
"Yeah, yeah, Professor. I'll take care of it."
Her cheeky brother replied with a smirk as he grabbed the rag. She gazed at his reliable back. Secretly rubbing her thighs together.
How could anything feel this good? How could she be this happy? The curse of the magic tool didn't scare her anymore. She could just devour this boy's love every day. Savoring their sibling secret.
Seo-ah's perspective
A few days later. Late afternoon. She was heading from the Professor Dorm to the Admin Building.
Warm sunlight. Her condition was peak, thanks to the semen pumped full that morning. The discomfort of clenching to keep it from leaking? Just another happy game.
That's when.
Seojun!
A familiar figure by the bench. Her sturdy little brother stood there. She brightened, voice rising unbidden.
"Seoju—"
But her face twisted in fury.
Right beside him.
"Help me out. I seriously have no clue how to do this."
A pretty little bitch. Same department? Giggling as she poked his arm. Flashing fox-like eye smiles.
"Oh, that? Gimme. I'll help."
Seojun smiled back, taking her laptop.
Grind.
Her teeth ground unconsciously.
What the fuck?
Who the hell was that slut hitting on her brother? Touching her man's arm? And why was that idiot Seojun grinning like a fool?
Black emotion surged like sewage.
"...!"
Suddenly. A nasty pain exploded in her gut. Cold emptiness as her insides drained.
Wha...? No, don't.
The semen stuffed that morning. Plenty to last till evening. Yet it vanished in an instant, sucked dry by her starving womb.
Grrrr...! Slosh!!
"Hahk...!"
Her knees buckled. She grabbed the lamppost desperately.
Sudden heat. A ferocious thirst unlike anything before.
The magic tool's curse had mutated. Crisis of losing her male triggered it.
Possessiveness.
Jealousy fused with the curse birthed a monster.
Splurt!!
"Nngh... Ahh..."
Her crotch soaked uncontrollably. The emptied mound frothed madly. Filthier than ever, twice as vulgar love juices. Jealousy-soaked sludge of murky desire. Sticky like melted cheese.
That bitch dares.
Her vision flashed red.
Gave me his seed.
Turned my hole into a cumrag.
And hits on another girl?
Smiles at another slut?
Her walls quivered. Womb rang alarms like mad. Drag that male here now, stuff him in. Cram full of semen, mark with mating proof.
"Haa... Haa..."
Breath choked. She bit down till her teeth might shatter. Wanted to charge, rip that fox's hair out. Strip Seojun's pants in front of everyone, mount him. Scream he's mine. My man. Feeds only my womb.
But. She's a professor. Gritting teeth, she reined in reason. Trembling hands pulled out her smartphone. Sweat—or tears?—dropped on the screen.
Seojun's perspective
"So if you plug it in here, the value calculates properly..."
He'd fixed it, handing back the laptop.
Vrrr—! Vrr! Vrr! Vrrr—!!
His pocket smartphone went berserk. Relentless vibration barrage.
"Uh? Hold on."
Excusing himself, he pulled it out.
What the...? A chill crawled up his spine. This wasn't normal. Not her usual vulgar begging. Pure rage. And killing intent.
We fucked twice this morning...? No way it's worn off already.
No time to think. Something was seriously wrong.
"Uh, something urgent came up. Sorry. Here's your laptop."
"Huh? Oh, yeah. See ya!"
He ditched his flustered classmate and bolted like mad.
Seojun's perspective
"Haa, haa...!"
His breath burned in his throat. What the hell happened? No way the semen wore off already. Did the magic tool's curse mutate?
Clunk!
"Noona!"
He flung open the door. And—
Whoosh.
"Ngh..."
Overwhelming stench. Rancid sourness mixed with cloying sweetness. The bizarre reek of a bitch in heat.
Noona stood there. Clothes normal. But her skirt hiked grotesquely to her waist. Panties shredded on the floor.
Between those legs.
Drip. Plop.
Thick, sticky mucus like melted cheese. Vile sludge spewing nonstop from her pussy onto the floor.
Her eyes gleamed feral, dripping venom and murder.
"N-Noona! You okay?! Hurt anywhere?"
He rushed close, reaching to check her.
"Shut up."
Icy voice. Grip!
"Ghk...!"
Breath cut off. Seo-ah seized his collar with beastly strength, sanity gone.
"Who the fuck was that bitch grinning at you."
"Wha...? What're you—"
"That slut hitting on you and laughing, who the fuck is she!!"
She snarled, baring teeth.
Ah. The classmate from the bench. She'd seen that.
"No, Noona, it's not—"
"Shut it."
Crash!
"Ugh...!"
Seo-ah hurled him roughly. He slammed onto the desk edge, waist bent half-fold.
Smash!
Her pale arm swept everything off the desk.
Whip!
She yanked his pants without warning. Belt and zipper tore free pathetically.
But.
What sprang out was a limp dick. Shriveled from the sudden violence and shock.
Shock. Her eyes rolled white at the sight.
"Y-You fucking... kidding me?"
Her hands clamped the shaft viciously. She shook, twisted, kneaded like mad. The madwoman's grip exploded without reason.
"St-Stand it up! You fucker!! Get it hard now!! Don't fucking shrivel like a pussy!!!"
Squelch! Squelch! Bubble!
Seo-ah's swollen crotch. Sticky froth poured from gaping mucosa.
She smeared her skin with her own pussy slime.
"Ow! Noona, wait! Hurts, go easy...!"
"Shut up and get hard!! Why not?! Thinking of that ugly bitch, huh?!"
Fury. And then.
"Hwaaaang... Why won't it stand... My little bro's cock died... Hic, uuh... It's Noona's, why won't it stand...!"
Tears burst suddenly. Rage flipped to despair. Unpredictable emotional swings. She rubbed her cheek on his groin, wailing desperately. Saliva, snot, love juices soaked his crotch.
This unpredictable madness. Finally, terror-tinged arousal engorged his shaft.
"Ah, aaa... It's hard... Seojun's standing...!"
Seo-ah smacked her lips greedily. Hopped atop him. Spread her legs wide, ass raised.
"Noona, w-wait! Dropping like that sudden—...!"
His words fell on deaf ears. She slammed her hips mercilessly.
Squelch—! Rip—!
"Krrk...!"
He groaned in agony. Insertion so reckless even he felt pain. Heat and slickness doubting it was really a pussy.
Splurch!! Glorp! Splrrrk!!
Clinging like melted cheese, thick sticky fluids. Empty hole clenched wildly, swallowing the intruder. Ruthless pistoning crushed straight to her cervix. Delicate walls burst under pressure.
His heart sank.
Too rough...!
Fear surged. Noona, virgin till recently. Tender insides. No time to heal from frequent fucks. This would cause internal damage for sure.
“How's my little bro feel?! Good, right?! Noona's pussy's the best in the world, right?!”
She bellowed through desperate tears. Sure enough, faint blood mixed with fluids at their junction.
Bam! Bam!
"Noona! Please slow down...! You'll get hurt...!"
His pleas scattered into air. Seo-ah pinned his solar plexus with both hands.
“Why no answer! Why no answer! It's that bitch again, right?!”
