Chapter Title: Mom. Today's Class Was Fun.
-----------------------------------------------------------------
"Mom. Today's class was fun."
[The World Stops.]
Plop.
Min-seok's smirk froze on his lips.
"Why the fuck does this asshole always talk like such a prick?"
Alright, let's get started.
I scooped up Yu-na, who was sitting next to me, in one smooth motion.
I planted her facing him, straddling his lap.
I unbuttoned her blouse.
Pulling down her bra, her pale breasts bounced free.
"You want it too, don't you, sis?"
I hiked her skirt up to her waist.
I shoved her panties aside.
Her slick pussy rubbed against the front of Min-seok's pants.
I dropped my pants.
I pulled out my raging hard-on, ready to burst.
Grabbing her hips, I slammed her down hard.
Squelch.
"Nngh..."
A deflating wheeze escaped Yu-na's throat.
Frozen flesh.
But inside, it was different.
The moment her inner walls sensed the intruder, they heated up fiercely.
A tight, unyielding pressure gripped me perfectly.
"Watch closely, you fucker. This is your girlfriend. My sister."
I cackled right in his ear.
Not that he could hear me.
Using his knees as leverage, I thrust my hips wildly.
Thwack. Thwack. Squelch.
"Hng... Nngh... Nnngh..."
Every movement compressed Yu-na's lungs.
Muffled moans burst out.
Her nipples dangled and swayed right in front of Min-seok's nose.
Her sopping arousal dripped steadily onto his pants.
His slacks were stained and sticky.
"She's squeezing so tight."
The inner walls were writhing unnaturally.
Every vaginal fold sucked at my glans like a tentacle.
Her cervix winked invitingly, beckoning me deeper.
Outwardly a prim office lady, but inside she was a starving whore.
Thwack! Thwack!
I stomped her hips down harder, pounding away more brutally.
I grabbed her hair and yanked her head back.
Her unfocused eyes stared blankly into space.
[Elapsed Time: 30 Minutes]
Time's up.
I clamped my hands around her waist.
I thrust deep, as if to pierce her womb.
Spurt, spuuurt!
"Hnnngh...!"
A deflating wheeze.
Semen flooded into her womb.
At the same time, milky fluid gushed out over Min-seok's lap.
His pants were a soaked rag.
Serves him right.
I lifted Yu-na off his lap.
I dumped her carelessly on the floor.
"Now, what should I do next?"
I wanted to stage this one more dramatically.
It needed a convincing setup.
I got to work quickly.
"Like this... Yeah. Perfect."
Her skirt bunched up over her stomach.
Her panties barely clung to one ankle.
I positioned her right hand to grope her own breast.
Her left hand's index and middle fingers plunged into her cum-drooling pussy.
[Forced Pose Lock]
A deranged, mid-masturbation sprawl.
Brilliant.
I straightened my clothes and walked to the door.
I leaned against it, ready to watch the show.
Deep breath.
Snap.
[Time Flows.]
"...or maybe some overtime... Huh?"
Min-seok trailed off mid-sentence.
The empty seat beside him.
And the sticky, disgusting fluid staining his pants.
"Huh? What the hell is this?"
That's when it hit.
Yu-na's brain, sprawled on the floor, registered the signal.
"Huh...?"
Yu-na's eyes trembled.
Her focus blurred hazily.
The afterimage of 30 minutes of relentless pounding in her walls.
The hot, foreign fullness stuffing her womb.
And the sensation of her own fingers jammed inside.
"Ah... Uwaa..."
Her brain flashed white repeatedly.
A few seconds of silence.
Then.
"Kkhk! U, kyaaaaaaaah-!!!!"
Crash!
Yu-na rolled across the floor.
Her back arched like a bow.
"Ah! Aaaah! What is this! Urgh, haaaang!"
She clawed at her own breasts.
She didn't dare pull her fingers from her pussy—instead, she shoved them deeper.
Squelch. Squelch.
Her hips bucked on their own.
Like fucking an invisible man.
Splurt!
Every hip thrust sprayed frothy semen onto the floor.
"Y-Yu-na?! W-What's wrong with you! What the hell!"
Min-seok recoiled behind the sofa in horror.
His face screamed disbelief at the scene.
His prim girlfriend suddenly losing it and masturbating like a maniac.
[Status Ailment: Brain Overload]
[Status: Forced Continuous Orgasm]
"Nngh! Min-seok! I-I'm not okay! Something's wrong!! Uwaaaah!"
Yu-na bashed her head against the floor, eyes rolled back.
Foam bubbled at her lips.
To anyone watching, she looked insane—or a beast in heat.
I leaned crookedly against the door, clicking my tongue.
"Wow."
Min-seok whipped around to me.
His eyes mixed terror and disgust.
"Bro-in-law?! W-What the...!"
"Bro. Sis has been like this lately."
I cackled, twirling my finger at my temple.
"Too horny in front of her boyfriend, huh? Must be some disease. Can't-control-your-libido syndrome."
"What the...?"
Min-seok's gaze dropped back to the floor.
Yu-na was still splayed wide, thrusting her hips at nothing.
Panting like a dog.
"S-Sorry! Y-You're not feeling well! I'll head out first!"
Min-seok bolted for the door without looking back.
He fumbled his shoes in his panic and fled.
Only the drops of my cum trailing from his pant leg remained.
Bang.
The front door slammed shut.
The living room fell silent—save for the wet squelching sounds.
I strolled over to Yu-na slowly.
I grabbed her hair, still trembling in the aftershocks of pleasure.
"Tch. That disloyal prick. See that, sis? Better to dump a guy like him."
"Ah... Uwaa..."
She answered with a limp sigh.
Squelch.
Her crotch frothed and bubbled obscenely.
Lecture hall.
It was packed with students.
Up on the podium.
Mom—Professor Kim So-hee—was mid-lecture.
Neatly dressed.
She drew a graph on the board as she explained.
"As you can see from this indicator, volatility..."
I lounged at the very back, in the corner, chin propped on my hand.
Our eyes met.
Her brows furrowed slightly.
'Why are you here? Get out.'
Her icy glare said it all.
But what could she do?
The real lesson was just beginning.
I flashed a grin.
And.
Snap.
[The World Stops.]
Chalk dust hung frozen in the air.
The scribbling pens and murmurs vanished.
My world.
I rose leisurely and strolled to the podium.
Mom faced the board, back turned.
Arm stretched out writing.
Her tight skirt outlined her ass perfectly.
"Nice form."
I yanked her waist toward me.
Hiked up her skirt.
Black lace panties came into view.
I shoved them aside.
Her pussy was already slick and glistening.
She might not remember 'Mom,' but her body did.
What we'd done together.
"Professor. What am I gonna do if you get this wet during class?"
I tapped the entrance with my finger.
Twitch.
Squelch.
Her pussy lips quivered, spitting out a glob of arousal.
Like it had been waiting.
I unzipped.
Lined up my rock-hard cock.
And hilted it in one brutal thrust.
Splurt!
"Ngh, hngk...!"
A ragged gasp burst from Mom's rigid mouth.
Sudden invasion.
Her guts shifted upward, forcing the air from her lungs.
I started thrusting in earnest.
Thwack. Thwack. Thwack.
"Ngh. Nng... Hngh..."
Each pump jolted her body.
But her upper body stayed frozen toward the board.
Only her lower half dangled to my rhythm.
Tight.
And hot.
Her inner walls clamped insanely.
The squirming folds teased my glans.
The thrill of the students watching?
It clung even stickier than usual.
"Hoo, haa..."
30 minutes.
Nonstop pounding.
I felt her legs quivering.
Her pussy entrance was ragged like a dishrag, foaming white.
"Last one, Mom."
I gripped her hips tight.
Aimed for her cervix and struck.
Thwack!
Spurt, splurt!
"Kkh, nngh...!!!"
A metallic groan rumbled from her throat.
I coated the depths of her womb.
Twitch, twitch.
Her walls contracted and relaxed, drinking it in.
I plugged the leaking cum between her legs with some tissue.
Smoothed down her skirt and fixed her clothes.
She looked like the perfect professor again.
Though inside, she was a cum-soaked mess.
I cooled off with a sweat-wipe and returned to my back-corner seat.
Sank into the chair and watched her.
Deep breath.
Snap.
[Time Flows.]
"...So, this graph's downward curve..."
Mom continued as if nothing happened.
Tension gripped the chalk in her hand.
But.
0.5 seconds.
"Huh...?"
Her hand froze.
A chilling shiver raced up her spine.
Her lower belly felt heavy.
The sudden emptiness after being stuffed full.
And the sloshing liquid inside.
Her brain stalled.
Before she could process, the pent-up pleasure exploded.
Crack.
The chalk in her hand crumbled to dust.
"Hng, nngh...? Hngk!"
Her moan boomed through the mic across the lecture hall.
"P-Professor?"
Students murmured.
But Mom couldn't respond.
Her legs shook like aspen leaves.
She looked ready to collapse.
[Status Ailment]
"Ah, ngh, hngh...!"
She couldn't hold it.
Her cervix spasmed wildly on its own.
The tissue plug soaked through, then finally gave way.
Gush. Spurt.
Hot liquid poured between her thighs.
A sticky, lewd warmth trickled down her inner thighs.
Leaking her son's cum in front of the students.
"...Haa, nnght, hkk..."
Mom's eyes unfocused.
Pleasure-glazed pupils flickered.
Cold sweat poured like rain.
Her makeup smeared horribly.
"S-Sorry, hngk! Today's... class..."
She rubbed her thighs together.
Pressed her lower belly against the podium.
Swallowed her bursting moans desperately.
"...ends here... hngh!"
She staggered, grabbing her notes.
Or pretending to.
Her hands shook too much.
She nearly dropped the book.
"Haa... Haa..."
She had to escape.
Get out of here now.
Somewhere to dig it out.
Finger her pussy or masturbate.
Or scream in ecstasy.
Click. Click.
Her heels sounded precarious.
Each step sloshed her insides.
Her womb full of cum.
Its faint waves scraped her abused walls.
"Hngh... Nght..."
She halted mid-stride.
Clamped her thighs tight.
Rubbed them hard.
The itch between her legs was maddening.
Her skirt's underside was a disaster.
Inner thighs stuck and unstuck repeatedly.
'No. Please. Don't come out... Don't leak...'
No use.
Her pussy lips fluttered on their own.
Hot globs gushed out.
She clenched her ass tight.
Shuffled onward awkwardly.
"Ha ha."
Swallowing a sneer.
I followed at a leisurely pace.
Even her walk was entertaining.
"Ngh, nnght, ah...!"
Mom slumped against the hallway wall.
Her legs wobbled like jelly.
She scraped the wall to stand.
Stumbled toward the stairs.
One step.
Two steps.
"Ah, ngh, haaak!"
Stimulation everywhere.
Muscles moving down the stairs.
Even fabric brushing skin.
She gripped the railing like a lifeline.
Veins bulged on her hands.
Bumped her forehead against it.
Thrust her ass back.
Twitch. Twitch.
Her ass wiggled at empty air.
She hooked her inner thigh on the railing edge.
Grinding hard, moaning.
"Something's wrong... So itchy... Nngh..."
Lucky break.
The stairs were empty.
Otherwise, they'd have seen.
Respected Professor Kim So-hee.
Clutching the rail, shaking her ass like a bitch in heat.
"Mom. Today's class was fun."
I grinned, trailing her relaxed silhouette.
