Incest
"Sis! Sis!"
"Mmph!"
I clap my hand over Yoonseo's mouth.
I pin down my blood-related big sister's body with my weight, making sure she can't get up.
My blood big sister's bushy pussy hairs poke out, scratching roughly against my little brother's balls.
My little brother's throbbing cock flops wildly on my blood big sister's belly, grinding against her skin.
I try to yank down Yoonseo's panties with my free hand, but her thrashing body makes it fucking tough.
It'd be easy if I just smashed her face in...
Fucking blood-related family feels no hesitation, but beating the shit out of her is a whole different level.
Especially smashing up a delicious-looking face like my blood big sister's...
I could do it once, sure, but thinking about the future, it's better to leave her intact without too much damage.
"Sis! Why you fighting it? Your pussy was drooling all over my cock...! Let's just fuck already, yeah?"
"Mmmph!!"
I tense my ass and thrust my cock like I'm stabbing her belly, drilling into her.
The soft feel of my blood big sister's flesh soaks into my dick.
"Fuck...! Yeah...! Ji-an's ass was never that great anyway... but just rubbing on Sis's belly is already killer!"
"Mmmph!!"
Yoonseo pounds my cheek with her fist, trying to shove me off.
You know it's pointless, you fucking bitch...
Just spread your legs nice and wide and take your little brother's throbbing cock in your big sister's pussy!
I bend my legs, then stretch them down, praying her panty string catches on my toe by chance.
Fuck, not working.
Yoonseo's snow-white legs clamp together as she flails.
"Ah, fuck! Stay still, damn it!"
"Mmph!! Mmmph!!"
This isn't working.
Time for a decision.
I pull my hand off her mouth and use animal reflexes to spring up fast.
Then I grab the strings of her gray panties with both hands and rip them down rough.
"Kyaaak!!"
They're not fully off, but dragged down to her ankles.
I use every ounce of strength to rip the panties off her ankles.
"Minwoo! No!"
Sis tries to sit up again.
I lunge forward, hooking my arms behind her back, and slam her down onto the bed.
I crush her with my body, prying at her clamped legs with all I've got.
My little brother's cock hairs brush her pussy bush.
I shove my right leg between her clamped thighs.
Shake it to make space.
I worm my body between her snow-white thighs.
Fuck, I feel like a goddamn worm.
Not perfect, but I've half-slid between her legs now.
I reach out, cover her mouth again, and wiggle my hips to find her pussy hole.
Feels all slick... this bitch must've leaked a ton of pussy juice...
She's gonna get fucked anyway—might as well just take it, what's the harm?
My blood big sister's rough pussy bush tickles my groin.
I grind my body, ramming my little brother's cock into her big sister's pussy hole, drilling with everything I've got.
Suddenly, a slippery feel on my cockhead, then it catches somewhere.
Here!
I pull my hips back a bit, then slam my little brother's cock hard into her pink pussy.
Thud!!
"Gahk!!"
"Mmmmmmph!!!!!!"
My head snaps back.
Shoulders tremble, upper body pitches forward.
Ah... no... don't...
My eyes are rolling back...
I strain to force them forward, but it ain't working.
Foam bubbles at my mouth too.
Fuck...
"Ah...!"
As my upper body collapses forward, I summon superhuman strength, bracing both hands on the bedsheet.
I lift my head, eyes half-rolled, and start thrusting my hips.
My blood big sister's pussy walls clamp my little brother's cock like they'll snap it off.
That's why my eyes wanna roll—her pussy grip's insane.
The crushing pressure seeps from my dick through my whole body.
Against my will, my hips pull back, then slam forward.
"Hng...! Hng...!"
"Haaang!! Heung!!"
I wanna leer at Yoonseo's face, but my head won't lower from staring at the ceiling.
White foam spills from my mouth, dripping down my chin onto her tits.
Every time I ram into her pussy, it's soaking wet, and my cock sinks root-deep in one go.
That's when I knew.
Yoonseo's pussy was waiting for my cock.
The instant it bottoms out, her pussy walls wrap my entire shaft tight, like they were made for it.
Like we'd always been one. Little brother's cock and big sister's pussy fused.
Every thrust makes wet squelching sounds, like something's splashing.
I don't need to look. Pussy juice is gushing out around where our genitals join.
"Ah...! So fucking good, Sis...! Sis...! Yoonseo...! Fuck!"
"Heung...! Haaaang...! Eung...! Minwoo...! Heung...!"
"Yeah...! I can't do without you now, Sis! Only your pussy!!"
My mind clears.
Strength floods back.
My rolled-back eyes right themselves.
Foam clears from my mouth.
I lower my head to leer straight at Yoonseo's face.
Her eyes half-rolled, white foam on her lips as she moans.
I shove my face in, sticking my tongue into my blood big sister's mouth.
My tongue slips between her slightly parted lips.
I lift my hips and slam down, tongue-fucking her mouth.
I lap up her sweet sister spit and swallow it down.
Thud! Thud! Thud!
The bed creaks from the recoil of my thrusts.
Every root-deep plunge into her pussy makes sloppy squelching noises.
Our moans blend and echo through the room.
"Guh...! Gahk...! Sis...! Sis...!"
"Heung...! Haaaaang...! Heeeeeung!!"
I feel the orgasm building.
My little brother's cock swells deep in her pussy.
I thrust with all my might.
Pull back, gather power.
My cockhead catches in her pussy hole.
Slam my little brother's cock hard into her pink pussy hole.
Thud!!!!
The instant my little brother's cock spears through her pussy walls root-deep.
Her pussy flesh wraps my entire shaft tight.
Something rises from my toes.
Up my thighs, past my ass.
From my balls, up the shaft, past the head—exploding out powerfully.
"Kraaak!! Krack!!"
"Haaaang!! Heung!!"
My head snaps back to the ceiling.
Hips buck up against my will.
My little brother's cock slips out of her pussy.
Bucking hips slam down hard.
And once more, my cock rams deep into her pussy.
From my balls, up the shaft, past the head—cum blasts out powerfully.
"Uaaa...! Aaaa...!"
"Heung...! Eung...!"
Massive loads of cum erupt from my cockhead, filling her pussy to the brim.
My whole body's drenched in sweat.
Mouth agape, tiny tremors.
Eyes try to roll but snap back.
Insane pleasure smashes my brain.
"Aaaa...! Aaaaa...!"
"Heung...! Eeeeeung...!"
A feeling I've never known.
Like my body's not mine.
All my strength sucked into Sis's pussy.
Her pussy walls cling to my cock, milking the head relentlessly.
Body twitches.
Then slowly, I start thrusting again.
Consciousness flies away; instinct takes over.
My little brother's cock doesn't wanna leave her pussy walls either.
Thud! Thud! Thud!
"Keur...! Haa...! Eur...!"
"Heung...! Haa...! Eung...!"
Eyes half-lidded, mouth wide, drool pouring.
Vision blurs, unfocused.
Only the feel of her pussy gripping as I lift and slam my hips.
Suddenly, a squeeze like she's wringing my cock dry—blinding white in my head.
Thighs lock rigid.
"Kraaat...! Sis...! Aaaat...!"
"Haaang...! Keuung...! Heung...!"
I force my head down to leer at my blood big sister's face.
She's twisting wildly, hands gripping the headboard, taking my cock with effort.
Her snow-white cheeks flushed red against pale skin.
Her snow-white legs wrap my back, ankles locked.
Groins grind, cock and pussy fused.
I lift my hips like I'll break the bed, then slam down.
My cock slices her pussy depths root-deep.
Her pussy clings, dragging out along my shaft like it won't let go.
I ram back in, piercing her dragged-out lips deep.
"Sis...! Sis...! Gahk...!"
"Eung...! Haa...! Keuung...!"
My cock swells like it'll burst.
Something's about to explode.
Insane pleasure hammers my cockhead.
Hips snap up against my will.
Her pussy releases my cock.
It springs fully out.
I gather all my strength in my ass.
Then slam my little brother's cock deep into her pussy.
Thud!!!!
"Kraaaaaat!!!!!!!!!!"
"Haaaaaaaang!!!!!!!!!!"
Yoonseo bolts upright, wrapping her arms around my back.
I wrap my arms around her waist, pulling her tight.
Minwoo and Yoonseo face-to-face, screaming, bodies shuddering.
Chests press, cock and pussy one.
Like from the beginning of time, big sis and little bro climax as woman and man.
