Chapter 7: Sibling
Thighs and buttocks collide, making rough friction sounds.
The older brother's cock pierces through the younger sister's anus, thrusting all the way to the root.
As if it had been waiting, the flesh inside the anus wraps tightly around the entire cock, clinging to it.
The younger sister's anal flesh squeezes the older brother's cock as if it's about to snap it off.
A grinding sound comes from the gap where cock and anus meet.
Clear fluid splatters everywhere.
"Hoo... I gave one to each of the other girls too, but I never saw them use it... It was custom-made and expensive, you know."
"Mm... I use it five times a day... to masturbate, oppa... Jun-seok's cock looks just like yours, too."
"Hehe... I'm curious how big that bastard's cock got... Well, I'll see for myself next month..."
"Haang... Move, oppa... your little sister's anus... no, my ass..."
A few years ago, I had a dildo custom-made after my own cock.
Since I only had one cock, I felt the limit of trying to fill so many pussies.
At first, I saw them use it a bit, but as time went on, usage dropped.
Well... nothing beats a real cock...
Maybe when science advances, I'll have ten real cocks attached and fuck them all at once?
Lost in thought, I feel my cock melting inside.
Yu-jin's sweat-soaked butt clenches tight, and her brother's cock, thrust to the root, is nearly snapped off.
"Khak... Take it easy, you fucking bitch... Your ass feels amazing since you started working out lately... huh?"
"Mm... I have to take Jun-seok's cock soon... He's my son... Can't have him disappointed after tasting mom's pussy..."
"Hehe... Yeah, have mother-son incest with that bastard first... then I'll shove in two cocks at once and rip you open..."
"Nnh... How?"
"First, I'll reveal I'm his real dad... then I'll take your ass, and Jun-seok will take your pussy."
"Kyaang... Jun-seok..."
I haven't even started thrusting, but already feel like I'm about to cum.
I use all my strength to suppress the urge.
The bitch lying face down tries to gaslight her mind, pretending her pussy isn't a regular one without blood ties.
Soon, the urge to cum subsides.
I slowly start moving my hips.
Thrust. Thrust. Thrust.
The younger sister's anal flesh clings to the older brother's cock and gets pulled along.
Then it gets thrust deep inside along with the cock.
Yu-jin's head snaps back, mouth gaping wide.
I grab her hair and twist her head around.
Her eyes roll halfway back, mouth open, drooling foamy spit.
I gather saliva in my mouth and spit it right onto Yu-jin's face.
"You know, right? Once you fuck Jun-seok, you'll be a full-on parent-child fucker..."
"Mm... Haang... Like Ji-eun?"
"Well, you don't have to go that far... Just don't forget your duty as a cockhouse for Jun-seok whenever he gets horny."
"Mm... I know... I'm already doing that... He comes home on leave sometimes..."
"Hehe... That bastard must jerk off thinking about your pussy every day, huh?"
"No... I don't think so... When he comes home on leave and I suck his cock, the cum is so thick..."
"He's been saving it for his mom's mouth, huh... But soon, you'll take it in your pussy, right?"
"Mm... I'll take my son's cum in my pussy... and make a baby, too..."
"Very good... Compared to those useless bastards Woo-joo and Suho, Jun-seok will be the first to take his mom's pussy."
There's a month left until Jun-seok is discharged.
Next week, Woo-joo and Suho will get out, leaving three weeks.
Seeing the state Mom was in after I just fucked her, three weeks is plenty to pull off mother-son incest.
What I'm worried about is Woo-joo and Ji-hoon...
How the hell do I get those bastards to have mother-son incest with Mom?
Whatever, I'll ignore it for now.
No need to worry about the kids when I'm fucking my little sister's ass.
Come to think of it, I'm a hell of a parent...
Where else do you find parents who worry about their own son and daughter like this?
Be grateful you were born to a parent like me, you fucking brats.
I thrust into Yu-jin's pussy with all my might, as if to tear it apart.
Thrust.
The two siblings, drenched in sweat, connect cock and anus.
Before I know it, pussy juice is leaking out from between.
I feel the urge to cum rising.
"Kyaang... Oppa, my little sister's ass is swelling up... your cock..."
"Yeah, just thinking about those bastards fucking Mom gets me so damn excited... and about taking my daughter's pussy too..."
"Ahang... What about Doona... how will you take her?"
"Huh? First, I'll take care of the inbred pussies holed up at home... Yuri, Yura, Ji-young first."
"Okay, I'll make sure Doona doesn't give her pussy to any bastard without blood ties until then..."
"Yeah, that's what a real mom should do... For a real daughter's pussy, nothing beats having her real dad break her in."
"Aang..."
"For her first time, I'll set up about ten cameras and record every cell... Hng..."
"Mm."
I pull my hips back so only the cockhead is hooked in Yu-jin's ass.
Her anal flesh clings to my cock.
After pounding like crazy, the area around Yu-jin's ass is red.
She bites down so hard on her drooling mouth it could break her teeth.
With all my strength, I slam my cock into my little sister's ass.
Thrust.
...The moment the older brother's cock, clinging to the younger sister's anal flesh, is thrust all the way to the root.
A tingling sensation smashes my head, runs down my shoulders, then through my belly to one of my balls.
At the same time, a tickling feeling runs from my toes, through my thighs and butt, to the tip of my balls.
The tingling and tickling sensations meet at the tip of my balls.
Like being struck by lightning, my body twists as I thrust deep into my little sister's ass.
My balls shrivel up tight, and something thick surges up my shaft.
Finally, my cockhole bursts wide open.
From deep inside my little sister's ass, white, watery fluid shoots out at light speed.
"Khaaaaat!"
"Kyaaaaaaang!"
Brother and sister, cock and anus connected, snap their heads back.
Their whole bodies tremble, mouths wide open, drooling foamy spit.
Eyes rolled completely back, they casually commit sibling incest that's been going on for decades.
"Haa... That was good, Yu-jin..."
"Haa... Yeah, oppa... Now I know why I don't use the dildo... Nothing beats your real cock..."
"Hehe... Is that a compliment? A dildo is just a fake cock, after all..."
"Yeah... Until Jun-seok is discharged, stop by often... I'll keep my pussy and ass clean..."
"Sure, and think up a plan to break in that bitch Doona... She's your daughter, you know her best."
"Yeah... But... is that really necessary? With your cock, you could just pounce, like you did with my sister..."
Yu-jin's right.
When I first fucked my real older sister, Yun-seo, I just pounced on her.
After a few thrusts, she passed out cold.
I ignored it and came inside her.
There were some episodes before and after, but in the end, Yun-seo fell for her little brother's cock.
"Hm... That was when I was twenty-one and full of energy... Now I have more to lose..."
"Hehe... Why so unlike you, oppa? You always said to live by your cock's whims... still do..."
"Yeah, you're right... Maybe I'm getting old, my personality's changing?"
"Haha... Didn't you say you'd take Yura too? She's close with Doona... think about it."
"Yeah, let's do that. It's not like these inbred pussies can run away... Just keep an eye on Doona's pussy."
"Mm... But... are you just going to keep your cock in my ass? I wouldn't mind another round..."
Hearing Yu-jin, I slowly pull my cock out of her ass.
My cock, still hard, pops out and sprays cum and pussy juice everywhere.
I glance at the clock and see it's already early evening.
I realize it's almost time for Doona to come home and sit on the edge of the bed.
Quietly, I light a cigarette, take a deep drag, and blow out smoke.
"Doona will be home soon... If we get caught, it'll be a pain, so let's call it a day."
"Yeah, haa... You came a lot, oppa..."
Yu-jin slowly gets up.
White, watery fluid drips from her gaping ass.
She ignores the cum running down her legs and sits next to me on the bed.
She takes out a cigarette and I put it in her mouth.
I light it for her with my own cigarette.
"Your stomach's totally flat now, huh?"
"Yeah, told you I've been working out... swimming, yoga, home training..."
"Hehe... Reminds me of Ji-eun... She worked hard on her body to fuck me too..."
"Yeah, I guess Ji-eun's blood runs strong... Looking back, I understand Mom's feelings now..."
"You used to call her Ji-eun all the time... Getting mature with age?"
"Hehe... Just saying... How's Mom's health?"
"Better than when I first fucked her... Might pounce on her as soon as Suho's discharged..."
"I'm curious... If you're free, I'll go check her out..."
"Don't go slapping her like you used to... In the end, it's all thanks to Mom that things turned out this way..."
"Yeah, oppa... I will... Now that we have plenty of inbred cocks and pussies, we can play with the others..."
Yu-jin leans her head on my shoulder.
The naked siblings share a smoke together.
She gets up, heads to the bathroom, quickly washes up, changes clothes, and gives me a light kiss.
We leave the house together.
Just then, the front gate opens and a familiar face appears.
It's Doona, the daughter born between Yu-jin and me.
"Hello."
"Hey, coming back from class?"
"Yes, are you heading out?"
"Just stopped by for a bit... Here, allowance."
I pull out a wad of bills from my pocket.
After a moment's thought, I take out ten 50,000-won bills and press them into Doona's hand.
Doona hesitates, glances at Yu-jin, then reluctantly accepts.
"Thank you."
"Yeah, don't overdo it... Take it easy."
"Yes, goodbye."
Doona bows at a 45-degree angle with both hands together.
Damn, what a polite girl.
Hard to believe she's the one born between me and Yu-jin.
For a moment, my eyes are drawn to Doona's bursting cleavage visible through her T-shirt.
Swallowing hard, I watch her walk into the house, her skirt so short her panties are almost showing.
Feeling blood rush to my cock, I resolve to break in Doona's pussy with her real dad's cock no matter what.
Leaving my regret behind, I head to the house where Yuri will show herself in her underwear to her real dad.
