"Hehe... My head... it's empty..."
Squirt.
A frothy spray of white foam gushed out.
Her pussy gaped endlessly.
"Hoo."
I caught my breath.
Yu-na's eyes had rolled back, her tongue lolling out.
This seemed sufficient enough.
But something was missing.
A proper 'period' was needed.
Kang Min-seok.
Dunk that arrogant prick.
A finishing blow to shatter even the lingering dregs of attachment.
"Hmm."
I straightened my pants and glared at Kang Min-seok.
Frozen solid with time stopped.
'Filthy bastard.'
She's my plaything.
I can't hand my sister over to a scum like him.
That's when his right hand caught my eye.
"Ah."
The corner of my mouth curled up.
That was it.
That would be perfect.
In size and meaning.
"Mind filling in for me? Big bro."
I grabbed Min-seok's hand.
Molded it into a tight fist.
"Sis. Incoming gift?"
I spread Yu-na's legs wide.
After 130 minutes of pistoning, she was thoroughly loosened up.
Her inner walls were a sloppy mess, the entrance gaping loose.
"Gonna need some lube."
I fetched a syrup bottle from the counter.
Poured it over Min-seok's fist.
Sticky sugar syrup coated the skin.
Then layered on Yu-na's juices and my semen.
Soon it was a slick, slippery mess.
I pressed it against her entrance.
Squelch.
I began pushing it in slowly.
No matter how stretched, a fist was a hefty size.
But not impossible.
"Hngggg..."
A hissing sound leaked from Yu-na's mouth.
Her mucous membranes writhed, accepting the intruder.
Slipping through gaps lubricated by syrup and fluids.
Slowly.
Heavy.
Fingers sank in knuckle by knuckle.
The back of his hand stretched the entrance taut as it burrowed.
Streeetch.
The sound of mucosa stretching to its limit.
"Haha. Going in better than expected?"
Thanks to all the prep work so far.
Yu-na's hips trembled violently.
Convulsions.
Bio-Response Activation: Vaginal Walls & Uterus
Status: Extreme Accommodation
Her hip joints and muscles screamed as they stretched.
His entire forearm slurped right in.
Up to the wrist.
"Whoa... it's completely stuffed."
Yu-na's lower belly bulged out.
Her uterus and organs displaced.
The outline was vividly visible through her skin.
"Perfect."
I shook off my hands.
Kang Min-seok was in a half-risen stance.
Right arm extended, fist jammed between Yu-na's legs.
Yu-na sprawled on the table, having swallowed it whole.
Anyone could tell at a glance.
Sadistic intercourse.
Sexual abuse.
Fisting.
"Shall we start?"
I stepped back.
Pulled out my smartphone and framed the shot.
The two in their lewd act filled the viewfinder.
Ready.
I snapped my fingers.
Snap.
Time Flows.
Silence hung in the air.
Min-seok's pupils shifted.
The sensation of sipping coffee vanished.
Replaced by a wet, hot, tight unfamiliar pressure.
"...Huh?"
Min-seok let out a dumb noise.
His gaze trailed down his shoulder.
His forearm was gone.

Buried inside Yu-na.
At the same time.
"...?!"
Yu-na's eyes flew wide.
She couldn't even scream.
130 minutes of internal ejaculation.
Her belly stuffed full with massive volume.
The enormous stimulation crashed over her brain all at once.
Far beyond capacity.
Snap.
Reason snapped.
"Ah... Aah... Agyaaaah?!"
The belated scream erupted.
A bizarre sound indistinguishable from pain or pleasure.
A beast's single cry.
"Hiaaah!! So full! Too big! My belly! My belly's stuffed full!!"
Yu-na's back arched like a bow.
The table rattled.
Cups and plates crashed to the floor and shattered.
Crash!
"Gah?! What?! What's this?!"
Min-seok shrieked in horror.
Unable to comprehend.
Why is my hand jammed in here?
Terror.
Min-seok yanked his arm back.
It didn't budge.
"Huh...?"
He pulled harder.
Not even a twitch.
Squelch.
Yu-na's vaginal muscles contracted.
Like a suction cup, clamping his arm tight and refusing to let go.
Vaginal spasms from the extreme stimulation.
"W-what?! Why won't it come out! Why won't this come out!!"
Min-seok screamed in panic.
Each tug dragged Yu-na's body along.
"Nghhk! No! Don't pull it out! It's so full and good! My head! My head's going white!!"
Squelching fluids ran down her thighs.
Yu-na's eyes rolled back as drool spilled.
Every movement of the fist inside shook her brain.
"Let go! Let go of it, you crazy bitch!"
Min-seok tried shoving Yu-na's shoulders.
But her lower body had no intention of releasing.
"Kyaaak!"
"What the hell?"
"A guy's fist in a woman...!"
The cafe erupted in chaos.
People jumped to their feet.
Horror and shock.
Click! Click! Click!
Smartphone shutters fired in succession.
Dozens of lenses aimed at Min-seok and Yu-na.
"N-no! This isn't what it looks like! I didn't do this!"
Min-seok wailed toward the cameras.
His face drenched in cold sweat.
"It's a misunderstanding! My hand suddenly... it just went in!"
Who would believe that.
It was a blatant sex crime scene.
"H-hey! Someone call the cops! Stop this guy!"
I burst forward.
Oscar-worthy acting.
"Bro! What the hell are you doing! What did you shove in my sister!!"
I grabbed Min-seok's collar and shook him.
"N-no, Hyun-min! I swear it's not me!"
"Don't lie! You're killing her! Pull it out! Pull it out now, you bastard!"
"It won't come out! I'm dying to pull it out too!!"
Min-seok was sobbing uncontrollably.
Contemptuous stares from the crowd.
Cameras recording everything.
His life ended here.
Weee-ooo weee-ooo.
Sirens wailed in the distance.
"Heee... uuu..."
Yu-na's movements ceased.
Her unfocused eyes stared blankly at the ceiling.
Savoring the fullness crammed between her legs.
Tremble.
Her body twitched sporadically as she lost consciousness.
"Sis! Snap out of it! Sis!"
I hugged Yu-na and shouted.
Her limp mouth.
A smile lingered.
A peaceful smile.
Emergency room.
The commotion had settled for now.
Min-seok barely extracted his hand with the paramedics' help.
Of course, he got an earful of abuse in the process.
Even as the police dragged him away, he protested his innocence.
Futile.
Sex offender stigma. Internet immortality.
He'd never show his face in society again.
And Yu-na was transferred to a room.
"Are you the guardian?"
The doctor approached, checking the chart.
"Yes. I'm her brother. How's my sister...?"
"Fortunately, no threat to her life."
The doctor adjusted his glasses.
"Some lacerations around the genitals, but we've sutured them. With rest, no major issues. However..."
"Her head—my sister's head? She was foaming at the mouth earlier."
He paused briefly.
Flipped through the chart with a sigh.
Then lowered his head.
"Extreme shock and trauma to the brain. MRI shows... damage to the frontal lobe."
"Damage? Like dementia?"
"If it's temporary shock, we'd be lucky, but currently, permanent cognitive impairment is suspected."
Perfect.
The exact result I wanted.
"Ah... I see..."
I staggered, feigning shock.
"Poor sis... caught by a monster..."
"Brace yourself mentally. We've given her a sedative; she'll wake soon."
The doctor left.
Silence.
Yu-na lay on the bed.
Pale arm hooked to an IV.
Her face serene.
Twitch.
Yu-na's fingers moved.
She slowly opened her eyes.
Dazed, clear pupils.
No weariness of life, no shame.
Pure, innocent gaze.
"Sis."
I called softly.
Yu-na's head turned sluggishly.
Our eyes met.
A moment of silence.
Her brain processing info.
And then.
"...Hyoon-min?"
Slurred speech.
Lisping.

"Hyuu... min-ah..."
"Not Hyoon-min, Hyun-min. Say it after me."
"Hyun-mii... ni? Hehe..."
Yu-na grinned wide.
Drool pooled at her mouth.
Face free of worries or concerns.
"Hehe... My head... it's empty..."
Yu-na tapped her head.
"Feels cool... nothing comes to mind..."
A true blank slate.
What about Min-seok then?
"Sis. Remember Kang Min-seok?"
"Kang... who?"
Yu-na tilted her head.
No acting.
She genuinely had no clue.
The lingering obsession and guilt that tormented her.
All evaporated clean.
"Who? Dunno. Hungry."
"Hungry?"
"Yeah. Hungry. But... this is hungrier."
Yu-na's hand slipped under the blanket.
Rubbed her crotch shamelessly.
Shame? Morality?
All that complexity burned away.
Only instinct remained.
"No thoughts... just itchy when I see it..."
She twisted her hips.
"Hyoon-min... give me something tasty..."
She kicked off the blanket.
Spread her legs wide.
White flesh exposed under the gown.
Gauze-packed pussy twitching.
"Hehe... I'm a real dumb dog now, right? Hyun-min's dumb dog, right?"
Yu-na's eye smile.
Happier than ever.
The human Choi Yu-na was dead.
Only the bitch remained.
"Yeah."
I stroked Yu-na's head.
She nuzzled my palm like a puppy, tail wagging.
"You're my lifelong fucktoy dog toilet now, sis."
"Yay! Love it! Fucktoy toilet yay! Woof!"
Yu-na beamed.
Bright, lewd smile.
Achievement Unlocked: Perfect Domestication
Target: Choi Yu-na
Status: Intelligence Decline, Absolute Obedience
With this, sis was fully mine.
A few days later.
The wheelchair wheels rolled.
Screech.
"Uuu... Hyoon-min..."
The occupant was a drooling woman.
My sister, Choi Yu-na.
"What's up, sis. We're home."
"Uhh... tired... carry me..."
Yu-na squirmed in the chair.
She'd been like this throughout discharge.
Clung to my arm the whole time.
"Oh my. Yu-na, you love your brother that much?"
So-hee giggled beside us.
Mom wasn't exactly normal either.
Half-lidded eyes.
Gaze darting to check my mood.
"Master, let me push? Please? Let me do it."
"No need. Mom, just carry the bags."
"Yesss... hehe. I'll carry the bags."
So-hee grinned ear to ear as she grabbed the luggage.
To others, we might look wholesome.
Or freakish.
Three huddled together, cooing.
A twisted family's return.
"We're home."
I opened the front door.
Spring.
Yu-na leaped from the wheelchair.
Stitches not even out yet.
"Pussy! Pussy!"
Yu-na yanked down her pants.
Pale ass exposed.
"Sis. What are you doing."
"Itchy... Hyoon-min... it's so itchy here..."
Yu-na spread her legs and lunged at me.
Eyes rolled back.
"Fuck me! Yeah? Scratch my pussy! Scratch it with Master's cock!"
Yu-na clung to my pant leg.
Surprisingly strong grip.
Beast's instinctive strength.
"Pussy! Cock in pussy! Yeah?"
Smack!
My hand slapped her hand away.
"Ah...?"
Yu-na looked up blankly.
Shock of rejection.
Tears welled up.
"Sis. Keep that up and your pussy'll be ruined forever?"
I laid down the law sternly.
Couldn't use it much yet.
No way I'd let the toy break early.
"Forgot it's all torn and stitched up? Doc said absolute rest."
"Uuu... but... but I wanna..."
"No. Stitches rip, you'll scar. Then I won't like it."
Yu-na's pupils shook like an earthquake.

"Nooo! Don't hate me! Waaah!"
Yu-na flopped to the floor.
Started rolling around.
Legs flailing in the air.
"Gonna do it! Gonna do it! Gonna fuck! Poke my hole!!"
Not even an animal.
Brain melted, no self-control.
