Your Dick and Cum Are All Mine!
"Our little brother's dick is mine too, his cum is all mine too. Right?"
[Seojun's Perspective]
"With that bitch!"
I slammed my hips up and down like I was trying to shatter the desk. Self-destructive pistoning that ignored my own body. Pleasure wasn't even on my mind. I just charged straight toward release.
"Since when!"
Squelch! Splurt!
"Have you been grinning like an idiot around her! Huh?!"
A torrent of curses poured out.
"It's not like that, I swear…!"
"Liar!"
"I told you, it was just a quick chat about homework…!"
The ravenous meat walls gasped and chewed on my cock. Every wrinkle in her pussy clenched like teeth, scraping viciously at the shaft.
"Please…! You'll ruin your insides like this, sis…!"
"Homework?!"
She spat in my face while pinning me down. Grinding her teeth, she glared down at me.
"I'm a full professor at this academy!"
Thwack!
"I assign the homework, I give the grades!"
"I'm the one who lectures with your cum stuffed deep in my pussy!"
Incoherent, rambling screams spilled out. Bang! Scriiiich! Her silver hair whipped wildly in every direction. The bitch thrashed her hips without a care for her breaking body. Eyes rolled back white, foam spewing from her mouth as she wailed.
"But you ignore me to help that slut with her homework?!"
============================
[Seo-ah's Perspective]
Bang! Bang! Every time her ass slammed down, her pussy entrance screamed. The inside felt like it was ripping apart. But she bucked harder, deeper. Riiiip—! Craaaack. Spuuurt! Grotesque tearing sounds erupted with each plunge. Thick, poisoned fluids gushed out, heavy and sticky like melted cheese, trailing long strings with the friction against my shaft.
Glurp! Glurp!!
Deep in her belly. Her womb convulsed madly, mouth gaping hungrily. It tried to swallow my cock whole, to make it part of her.
I was terrified. Losing my mind with fear. A whore who foamed at the mouth in heat at the drop of a hat. And crucially…
I'm a half-elf.
A body that couldn't bear Seojun's child. But that human girl? Young. Pretty. A normal bitch. She'd give him what I couldn't. She'd take his seed and swell up easily.
What if he throws me away?
What if he gets sick of me? Prefers a normal girl his age? Marries her and has kids?
I'll die.
My thighs trembled like leaves in the wind. The hand pressing on his chest went slack. The raging fury subsided. In its place, raw inferiority crept up.
"Hic… sob…!"
My eyes burned hot. Tears plummeted, soaking Seojun's chest.
Slap. Thud!
"You… hic! You like girls like that…?"
Twisting my hips, spraying cheese-like fluids, I sobbed like an abandoned beast.
"You prefer normal human girls?!"
I pounded my chest, screaming. Baring every hidden insecurity.
"Because my broken womb can't have kids… that's why you went after another bitch?!"
Tears streamed endlessly down my cheeks. I buried my face in Seojun's shoulder and bawled.
Terrified of not being loved.
============================
[Seojun's Perspective]
"…!"
My breath caught. The crushing pressure vanished. On my chest—her delicate shoulders quivering. My sister weeping her heart out.
Scriiich. Spuuuurt. Crack.
The pussy walls that had been gnawing like jaws gradually shifted. Sticky, heavy fluids glued us together like adhesive.
Terror. Inferiority.
Ah.
Just the blind, desperate attachment of one woman named Yoon Seo-ah. My heart ached. She was so pitiful it drove me mad.
I carefully raised my hand. Wrapping her slender waist tight around the tear-streaked, panting sister.
"Waaah, hic…!"
Her sobs grew louder. She rubbed her face against my chest like a child.
"Sorry."
I whispered softly in her ear.
"I didn't know it'd hurt you this much."
"Sob… huuuh…."
I gently cupped her trembling round ass. Sticky fluids oozed between my fingers. It wasn't dirty. Just heartbreaking.
"I won't even look at another girl."
"…Really…?"
A voice thick with tears. She flinched, lifting her head slightly. Our eyes met—hers filled with anxiety.
I nodded quietly. Wiping her wet cheek with my thumb.
"Doesn't matter if you can't get pregnant. Your pussy's the best in the world to me, so calm down now."
I flicked our joined hips. Squeeze—.
"Ah, uhn…!"
Resistance from the sticky membrane. I pushed through, pressing deep inside.
"I'll move slow so it doesn't hurt, sis. I'm not going anywhere."
"…Ah."
Seo-ah's body stiffened. Breath caught in her throat. Shiver shiver shiver!
"Aah…! Aaaaahhh!!"
Her eyes rolled back white. Foam bubbled from her lips.
"Haaaang! So good… Seojun, our little brother's coooock…!"
A beast's mating call laced with madness. Seo-ah buried her face in my chest and began grinding her hips languidly. The dance of copulation.
Splurt! Craaack! Squish!! Glurp! Glurp!!
Our mixed fluids spat out lewd friction sounds.
"Quick, fill my pussy tight with your cum…! Make this infertile pussy pregnant! Shoot lots and looots…!"
Desperate writhing atop me. That's how my sister threw herself in.
============================
[Seo-ah's Perspective]
"I'm not going anywhere."
The gentle whisper. The warmth wiping my tears.
Explosion.
Something burst pleasurably in my head.
He didn't treat me like a crazy bitch.
Said he won't run even if I can't get pregnant.
My vision flushed pink. Mine. My male. My little brother. My cock.
Sadism melted away like snow. Rage and inferiority fled. Extreme possessiveness flooded in.
Slipping down.
"Uhn… S-sis?"
I stopped bucking. Collapsing my upper body onto Seojun's chest with a flop.
Rub rub.
"Haaang… uuuh…."
Like a pet burrowing into its owner's arms. I rubbed my cheek against his bare chest over and over.
Scriiich…. Spuuurt. Splurt. Craaack.
The movements below shifted too. Clinging walls coiled flexibly like a snake. Gently rolling my hips, I licked lovingly at his shaft. Thick fluids climbed his groin.
Bubble bubble…! Pffft!
My pussy entrance spewed foam endlessly. Imprinting his scent. His heat. Everything into my body.
Lick.
"S-sis, that tickles."
I licked up his neck. Baring my fangs, I nibbled his skin. Chomp. Territory mark. So no other beast dares trespass. The brand declaring this is Yoon Seo-ah's.
"Seojunaa…."
A melted, drowsy whine. My eyes half-lidded in ecstasy. His face blurred dreamily.
"Our little brother's dick is mine too, his cum is all mine too. Right?"
"Y-yeah, I got it… uhn…!"
"Not a drop in another girl's womb… ugh?! Right?"
I pressed my hips flush and wheedled cutely.
"If you stick this in another pussy…."
Nipping his lower lip, I whispered.
"Sis will really die."
Doesn't matter if my pussy can't bear young. This boy's seed must live in my womb forever.
============================
[Seojun's Perspective]
I'm going insane. Waves of sticky friction crashing over me. The viscosity was insane. Every pull back felt like flesh tearing off whole. Blood rushed to my head.
Scriiich!! Squeeeze—!
"Hahk!"
Thousands of wrinkles clamped down on my shaft. Cheese-like mucus created a vacuum seal. Sucking like it wanted to devour every vein.
I can't hold back…!
My vision flickered white.
"Sis, I'm… gonna cum… grrh…!"
I tensed my thighs. Thrust my hips up hard.
Thwaaack—!!
"Aaaaahhh—!!"
Seo-ah's back arched like a bow. She clamped her pale legs tight around my lower half.
"Cum! Dump it all! Blow this infertile pussy to pieces!!"
Veins bulging in her neck. Mad screams. Her walls contracted mercilessly. My tip locked against her womb mouth.
Spurt spurt!! Splatter!
"Kyaaaaahhh—!"
She unleashed so much it felt like her belly emptied. Splash—!
Huh?
A strange dissonance flashed in my vision. Eyes dazzled. Seo-ah's lower belly—where her womb should be. A faint blue glow enveloped it.
Glurp! Gurrrgle!
Her guts writhed with eerie sounds.
============================
[Seo-ah's Perspective]
Imprinted. A thrill raced down my spine like a brand.
We're connected.
Breath. Pulse. Even souls. The magic tool answered my possessiveness. Binding his soul through his semen.
"Ah… aaaah…!"
Ecstasy like owning the world. Seojun's very existence rooted in my womb.
Ultimate orgasm. My brain boiled.
Shiver shiver shiver!
"Aaaaaahhhh—!!!"
My back snapped. Eyes rolled back. Foam trailed long from my gaping lips. I tried to scream, but only gurgles came.
Thud.
I collapsed limply. Vision went white.
============================
[Seojun's Perspective]
My sprawled sister. Passed out cold.
"…Haa… haa."
I panted too, drenched in sweat. My cock buried to the hilt. Our lower halves still locked tight.
Splurt. Splurt. Squish. Glurp.
Amazingly, her mucosa still writhed. Licking up the thick mix of fluids like it was devouring them. Even unconscious, contracting endlessly to suck it all in.
About five minutes. No, ten.
Twitch.
The silver hair on my chest stirred.
"Nng…."
Seo-ah groaned, eyes fluttering open blearily. Still dazed. But soon, reason settled in her long lashes. Focus sharpened.
"Hoo… haa…."
She drew a deep breath, propping her upper body slightly. Hands on my shoulders, looking down.
"…Yoon Seojun."
Calm voice.
"Y-yeah, sis. You okay…?"
Still joined, I panted back.
She tugged her skirt down casually over her waist. Then scowled hard.
"It's filthy."
"Huh? W-what suddenly."
"Open the third drawer over there."
Pointing at the cabinet.
"Wet wipes are in there."
"……"
"Hurry and grab 'em. Wipe this up. Ahem. What if it gets on the papers, seriously."
Unbelievable. Just moments ago, life-or-death frenzy. Splattered cum and fluids everywhere. Now that she's full, she snaps back to normal sister mode like a ghost.
Bubble. Glurp. Slick.
Under that prim expression. Her swollen hole still chewing my cock. The load still oozing back lewdly.
"Hurry and clean it. I have a remote meeting later."
So brazenly prodding.
"Haha…."
A hollow laugh escaped me.
"You're driving me crazy, seriously."
Yeah, this is it. This is my sister.
Slowly pulling out my lower half.
"Ohhk?!"
Her pussy popped free with a vulgar moan.
"Got it, Professor. Keep that hole clenched tight so my load doesn't leak."
"Sh-shut up! Just wipe the spill already!"
Her face flushed crimson as she yelled.
Snicker.
Laughter slipped out. Yeah, I prefer normal sis way more.
