"Did you hear? Mom's pussy feels so cool! Ahahaha! What a filthy slut!"
"Hyun-min, Mom's pussy is twitching like crazy. Must've been horny since morning. Dirty bitch."
Yu-na tapped Mom's cheek.
There was no reaction.
I opened my laptop.
Plugged in the pre-prepared USB and installed the webcam spyware tool.
Even adjusted the camera angle.
"All set. Now, shall we try putting this in too?"
I pulled a wireless dildo from my pocket.
A high-powered model with two vibration motors.
I crawled under the desk.
Her vaginal opening was drenched in fluids.
No need for lube.
Smoothly.
[Bio-Response Activation: Mucosa]
Time had stopped, but the hole was alive.
As soon as the dildo tip touched, the vaginal entrance squirmed out like it was welcoming it.
"Thanks for the meal. Right?"
Squelch.
I shoved it in all the way to the base in one go.
"Grrrrrr..."
[Pressure Detection: Internal Organs]
So-hee's belly pressed in from the overwhelming fullness of the foreign object.
A deflating hiss leaked out.
The inner walls clamped down hard on the dildo.
It sucked at it so voraciously, like it was possessed—no need to hold it in place.
"What a legendary pussy. A true masterpiece."
"Hyun-min, I'll take the remote."
Yu-na snatched the remote from my hand with a sly grin.
"You know when to do it, right?"
"Of course."
We erased all traces and leisurely slipped out of the lab.
A bit further away.
A deserted handicapped restroom.
We turned it into our control room.
I turned on the tablet.
The lab scene appeared on screen.
Mom sitting there blankly.
Yu-na hiked up her skirt and straddled my lap facing me.
The feel of her bare ass.
Down below was already soaked.
"Ready?"
Yu-na whispered as she slipped one wireless earbud into my ear.
I wrapped my arms around her waist.
"Let's start."
Snap.
[Time Flows.]
On screen.
So-hee's frozen pupils rolled around.
"...Huh?"
So-hee felt an odd sense of dissonance.
Her lower body felt heavy.
Like something was filling her belly completely.
"Ugh, eek...?"
The moment she tried to look down to figure it out.
Yu-na pressed the button.
Vrrrrmmmm-!
"Hya?!!!"
So-hee's body jolted up like she'd been electrocuted.
She barely grabbed the desk to keep from rolling off the chair.
"Kyaaak! Wh-what is it! Urgh! My belly, inside my stomach! Aang!"
The vibrations hammered her inner walls insanely.
So-hee trembled like a leaf and clamped her thighs shut tight.
Her pussy swallowed the dildo deeper, like a throat gulping food.
Knock knock knock.
"Professor? Are you okay? Is something wrong?"
A TA's voice came from the hallway.
Probably ran over after hearing the scream.
"...!"
So-hee's pupils dilated.
She didn't know what was happening, but one thing was clear.
If she got caught, it was over.
She bit her lip to swallow her moans.
"N-no, nothing... Ugh! It's fine!"
In the restroom.
Yu-na giggled and wrapped her arms around my neck.
"Ahahaha! Look at Mom's face. She's such a moron."
"Who's calling who a moron? Look at the slut sitting on her little brother with no panties."
"Hyaut?!"
I lightly scolded her and smacked her ass.
"Hey, Hyun-min. Can I put it in now? Watching Mom's face is making me so horny I can't take it."
Yu-na bucked her hips hungrily.
Well. If she's starving, feed her.
"Do whatever you want."
Yu-na's pussy swallowed mine in one go.
Squelch- splurt.
"Hyaaang!"
Yu-na threw her head back and mashed the remote button repeatedly.
Inside the lab.
"I-it's... just a bug... Hng?!"
The moment So-hee tried to make an excuse.
The vibrations slammed into her cervix.
"Grrrrrgh!!"
So-hee's nails turned white gripping the desk edge.
Her thighs quivered uncontrollably.
Her eyes rolled back white.
"Professor?"
"G-go away! Get out!!"
So-hee mustered her last shred of reason and yelled.
Fortunately, the flustered TA turned away.
"Y-yes... Understood. Call if you need anything."
The footsteps faded.
Only then did Yu-na hit the stop button.
The vibrations cut off abruptly.
"Haa... haa... haa..."
So-hee slumped over the desk, panting raggedly.
Her whole body was slick with sweat.
Her blouse went sheer.
Drip drip drip.
Her legs went slack between them.
Her pussy loosened.
The dildo that had been churning her insides slid out and plopped onto the chair.
"......"
So-hee stared blankly at the dildo.
Why is this here?
Did I put it in?
No way.
When, though?
She was confused.
But an even stronger sensation hit her brain.
'It's empty.'
The violated inner walls were now hollow.
Her vaginal entrance gaped regretfully.
"Haat... ugh..."
So-hee's hand moved toward her crotch on its own.
"Ah, no...!"
She startled herself and clenched her fist.
Was I about to masturbate just now?
But the embarrassment faded fast.
The new urge was hunger.
Fingers wouldn't cut it.
That full feeling.
That heavy pressure that twisted her organs—she needed it filled again.
Her gaze swept the desk.
Pen? Too thin.
Soothing spray? Too small.
Then.
An object on the display shelf caught her eye.
'Gratitude Plaque'
Thick crystal.
Heavy weight.
Cold, smooth edges.
Her honor.
"This'll do..."
So-hee picked up the plaque like she was entranced.
Her reason-lost brain spun a twisted logic.
"My pussy's... too hot... I need something cold..."
So-hee hiked her skirt up to her waist.
She leaned half-reclined over the desk.
Her heavy glass plaque engraved with her honor.
She pressed it against her slick, soaked pussy.
In front of the restroom monitor.
Yu-na and I held our breath in unison.
"Did you see...? Hyun-min?"
"It's a true masterpiece..."
Even we were stunned.
Because Mom was about to shove her own honor into her pussy.
The lab.
Splurt. Squish.
"Hnnngh...!"
The plaque's edge forced its way into her pussy.
The cold glass met hot mucosa, and So-hee's back arched like a bow.
"Agh! It's cold! Ugh! So... so big...!"
So-hee gripped the plaque with both hands and started shaking her hips wildly.
Her inner walls stretched to tearing.
The engraved 'Kim So-hee' scraped past her walls.
"Hyun-min... Ung! Me too! Harder for me too!"
Yu-na went wild watching the screen.
Mom's depravity became an aphrodisiac.
I gripped Yu-na's hips and thrust fiercely.
From the overwhelming sense of conquest I couldn't hold back.
Slap! Slap! Slap! Slap!
Mom's moans pierced through the earbuds.
"Agh! Feels good... Pussy feels so cool...!"
"Did you hear? Mom's pussy feels cool! Ahahaha! What a filthy slut!"
Slap! Slap! Squish!
The restroom and the lab.
Beastly mating echoed in both spaces.
On screen, So-hee rolled her eyes back and shoved the plaque to her womb's end.
"I'm cumming! Ung! Sis! Gonna cum!"
"Cum! Cum inside me!"
Yu-na spat on Mom's face on the screen.
My cock swelled.
Spurt spurt spurt-!
"Kyaaaaaaaah-!!!!"
The moment I flooded Yu-na's womb with semen.
On screen, So-hee threw her head back and screamed.
Spiiiish-!
Tidal squirt burst from the gaps around the plaque clenched in her pussy.
The desk soaked in urine and fluids.
So-hee trembled violently, plaque jammed between her legs, mouth agape.
"Haa... haa..."
The deed was done.
The restroom reeked of sex.
I brushed Yu-na's sweat-matted hair aside and removed the earbuds.
On screen, 'Professor' lay there blankly, plaque still embedded.
Her honor.
Steeping in the sticky fluids inside her hole.
===================================
1 PM.
Near the university, bustling street.
"Heehee. The weather's so nice. Right, Hyun-min?"
Yu-na clung to my arm, chattering away.
We'd just wrecked Mom moments ago.
No guilt on her face.
Her cheeks flushed with excitement instead.
"Sis, lower your voice."
"Why? I'm just in a good mood."
Yu-na deliberately rubbed her thighs together as she walked.
"My pussy's making such dirty noises right now. Guess I came too hard earlier from the excitement. It's all slippery every step."
Passing college students.
Salarymen.
They'd never imagine.
This innocent-looking beauty was going commando.
After rolling with her brother while watching her mom get defiled, dragging her soaked crotch around.
"Wanna grab some coffee? Recharge on sugar and cool our heads."
Sis's corruption was faster than expected.
"Tch. Fine."
We entered a conspicuous cafe.
Second floor.
Seat by the floor-to-ceiling window overlooking the street.
"Nice here."
"We look super visible from outside."
Yu-na sat with a dreamy smile.
Her expression twisted oddly.
"Eung..."
The chair's cold touch on her labia.
The sticky smear of dried cum and fluids.
"What? Embarrassed?"
"Feels like everyone's staring from outside..."
Yu-na put on a shy act.
Yet her legs under the table were already spread.
Two iced Americanos.
Slice of cake.
Peaceful afternoon tea time.
Sip. Slurp.
Yu-na rolled her tongue around the straw in her mouth.
Her eyes faced the window, but her attention was all on me.
Boring, huh.
A brain soaked in dopamine can't handle normal routine anymore.
Smoothly.
Under the table.
Yu-na's foot slyly probed my crotch.
Her toes scraped up the zipper line.
"Hyun-min."
"What."
"Bored."
"We came for coffee."
"Not fun."
Yu-na leaned forward.
Cleavage fully exposed.
She glanced around, then mouthed silently.
'Let's fuck. Yeah?'
Her toes pressed my cock firmly.
'Fucking here would be so hot. Make me pretty like Mom.'
The street outside teemed with crowds.
Cafe full of students studying or chatting.
Here? Of all places?
Really.
"Sis, you're a total pervert."
Perfect.
"You made me this way. Take responsibility."
I smirked without a word.
Great mindset.
She deserves a reward.
"Fine. As you wish."
I snapped my fingers.
Snap.
[The World Stops.]
Dead stop.
The noise vanished.
Music too. Laughter too.
People bustling beyond the glass froze.
I stood and approached Yu-na.
"Alright. Let's have some fun."
"......"
Yu-na was frozen mid-lustful expression.
Her eyes still brimmed with anticipation and desire.
I stripped Yu-na.
White t-shirt.
Short tennis skirt.
No underwear, so she was naked in seconds.
"Let's pose you a bit...?"
I pulled the chair right up to the window.
Turned Yu-na to face it.
Pressed her breasts and belly against the glass.
"Spread your legs."
I spread Yu-na's legs wide.
Perfect angle.
Anyone looking up from the first-floor sidewalk would see her pussy clear as day.
But I staged her upper body differently.
Keep that everyday vibe.
Put the Americano cup in her right hand.
Forced her muscles into a casual smile.
Complete.
Upper body like she's enjoying coffee.
Lower half spread wide, flaunting her hole to passersby.
Masterful dissonance.
