Chapter 6: Younger Sister
I stretch out my arms and pull Yu-jin into an embrace.
Moving my hips, I rub my rock-hard cock against Yu-jin's soft skin.
My hands, which had been wrapped around her waist, slide down and grab her soft, plump buttocks, one in each hand.
I bend my knees halfway, then stand up forcefully.
At the same time, I lift Yu-jin high into the air.
As if she'd been waiting for it, Yu-jin wraps her arms and legs tightly around her real older brother's body, locking her fingers together.
Slowly, I walk toward the master bedroom.
As always, I enter the password on the drawer in the corner of the TV stand and open it.
A dildo modeled after her real brother's cock catches my eye.
I pick up the dildo and turn on the switch.
A whirring sound fills the room as it wriggles like it's alive.
"When did you use this, you crazy bitch?"
"Um... five minutes ago."
"Heh... You can't go a day without your real brother's cock, can you?"
"Shut up and just fuck your real little sister's pussy and ass with your real brother's cock."
No matter how many times I experience it, Yu-jin and I are a perfect match.
She's such a fucking incest maniac that even I sometimes can't keep up.
She dreamed of mother-son incest with her real son, filling her womb with her real brother's cum.
In the end, her wish came true, and next month, Jun-seok, the son born between me and Yu-jin, will be discharged from the army.
Originally, he was supposed to enlist alongside Suho and Woo-joo, but it was delayed a bit.
That was all because of Yu-jin.
She didn't want to send her just-turned-adult son to the army without at least trying mother-son incest, so she seduced him first.
And the night before he left for the army, she crept naked into her son's room and did everything except actual penetration.
She sucked and licked her son's cock, and pressed her wet pussy against her son's mouth.
In a 69 position, she eagerly sucked her son's cock, and Jun-seok, caught off guard, ended up licking his mother's wet pussy.
In the end, Jun-seok came in his mother's mouth in that position.
Thanks to my earnest intervention, the act of actually shoving her son's cock into her pussy didn't happen.
I told her, if he tasted his mom's tight pussy before the army, how could he possibly endure all that time?
Fortunately, Yu-jin accepted her real brother's reasoning and sent Jun-seok off to the army without full sex.
Whenever Jun-seok comes home on leave, Yu-jin diligently drains the cum from her son's cock.
One day, as usual, Jun-seok came home on leave, and they snuck into a motel together.
After he came in his mom's mouth, Jun-seok confessed that he wanted to have full sex with her when he's discharged.
Of course, Yu-jin agreed without a moment's hesitation.
Unlike Suho and Woo-joo, who need some buildup, Jun-seok's mother-son incest is scheduled for next month.
"Yeah, even if you didn't say it, I was planning on it... Next month, when you and Jun-seok finally fuck, will you even think of me?"
"Of course, Jun-seok is Jun-seok... but you're still my precious incest cock, oppa... Now hurry up and fuck me, will you?"
"Damn, nothing's changed in twenty years... Fine, I'll give your pussy to Jun-seok."
I gently set Yu-jin down on the bedroom floor.
Then I spin her body around and tap her back.
Understanding immediately, Yu-jin spreads her legs wide in front of her real older brother.
She bends her upper body down and sticks her firm ass out.
Lifting her butt high, she blatantly exposes her dripping pussy and asshole.
"You're a real mom-pussy now... Unlike those other guys, you've already had a kid... with me... with this..."
"Hnnng..."
I shove the wriggling dildo deep into Yu-jin's pussy.
Her head snaps back instantly.
With her mouth slightly open, she moans uncontrollably, not caring if her real brother hears.
"Damn... How did you hold back? Your pussy juice is pouring out like a waterfall..."
"Yeah... it's been getting worse every day... Just thinking about mother-son incest with Jun-seok makes me like this..."
"You bitch... Tell me straight. Did you fuck Jun-seok or not?"
I raise my palm and bring it down hard on Yu-jin's firm ass.
A loud smack echoes.
I instinctively sense something happened between Yu-jin and Jun-seok that I don't know about.
"Unngh..."
"Not talking? You slut... Did you ignore your real dad and fuck Jun-seok?"
I smack Yu-jin's ass without mercy.
Her firm cheeks turn redder and redder.
Clear liquid pours down from where the dildo and her pussy meet, pooling on the floor.
"Ahh... unh..."
"Still lying? If you hadn't tasted your son's cock, your pussy wouldn't be gushing like this."
"Last time Jun-seok was on leave... we went to a motel... and for a moment..."
"Damn, you should've called your real dad then."
I clench my fist and smack Yu-jin's ass hard.
Her head snaps back, mouth wide open, drooling foamy spit.
I grab her hair and shake her, then toss her onto the bed.
"Ugh... oppa, I'm sorry... I was wrong..."
"Damn it... You should spread your legs and let your real son shove his cock in while your real dad watches."
"It wasn't like that... I just got too excited... Jun-seok only put the tip in for a second..."
"That's the same thing, you bitch."
"He pulled out right away... just the tip, for one second... His cock was so swollen it looked like it would burst..."
"You saw the video of me fucking Ji-eun for the first time, right? I came the moment I shoved it in."
Panting, Yu-jin slowly gets up.
She spreads her legs wide again, bends over, and sticks her reddened ass out.
Wiggling her hips, she begs her brother to fuck the pussy that's already been ruined by her son.
"I'm really sorry, oppa... I was wrong... But at least he didn't cum in my pussy... I'll take it from you instead..."
"Fine, it's in the past... Did you at least record it? Enjoyed such a show all by yourself, huh?"
"No... I was too flustered... Can't you let it go just this once? I'm begging you..."
Yu-jin shakes her ass desperately, begging for forgiveness.
Well... I guess it doesn't really count as full sex.
For mother-son incest to be complete, the real son's cock has to open the real mom's cervix deep inside her pussy.
Then the flesh inside her womb has to squeeze the son's cock and urge him to cum.
Finally, the son's cum has to shoot out at light speed and slam into the mom's womb for it to be done.
Fine, I'll let it go this time.
They're going to fuck for real once Jun-seok is discharged next month anyway.
Come to think of it, Min-a's return might line up with that.
The villa's remodeling is done too...
Heh, the picture's coming together.
"Yeah, what's done is done... Just fuck at the villa."
"Huh? The villa...? Oh..."
"Getting old, losing your memory? The villa where we first did brother-sister incest."
"I know, oppa... How could I forget... Even when my hair turns gray, I'll never forget the place where I had incest with you..."
"Yeah, we fucked in front of all the other pussies, with hundreds of viewers watching live... Do it like that again."
I remember the first time I fucked my real younger sister, Yu-jin.
Just like I said, we did a live broadcast, fucking in front of all the other girls I'd had.
I think we went at it eight times without stopping...
Missionary, doggy, side, standing, woman on top, every position we could.
Oh, and there was that time Yu-jin was floating in the air, holding onto the headboard, and I fucked her like a dog.
That video became a legend in the incest community...
I haven't streamed in a while, but if I go live, some bastards will show up.
"Ha... Like back then...? There were hundreds of people watching... Me and you... doing incest..."
"Yeah, remember? I'll set up the villa for the day Jun-seok's discharged, so do mother-son incest there."
"Hnnng..."
Suddenly, Yu-jin's body trembles like a leaf.
She lets out a scream mixed with a moan.
Her firm ass contracts, and her pussy twitches as if alive.
I instantly realize what she's about to do.
I quickly bend down and shove my face into Yu-jin's pussy.
Opening my mouth wide, I stick my tongue out.
"Kyaaaaaaaaaa!"
From deep inside Yu-jin's pussy, clear liquid gushes out powerfully.
The dildo, which had been buried to the base, pops out.
Her pussy juice pours out, soaking my mouth.
I do my best to drink as much as I can.
I spit the dildo out onto the floor.
"Mm... Fuck, it's delicious... Pussy juice from incest is the best... Right?"
"Ha... Fuck me, oppa..."
"Yeah, that was enough to pop the dildo out of your womb... Let's shove it back in."
I pick up the dildo rolling on the floor.
Then I shove it deep into Yu-jin's wet pussy again.
As the dildo and her pussy rub together, they make rough friction sounds.
"Hnnng..."
"Just thinking about fucking your son is making you itch, huh?"
"Yeah, oppa... I can't wait to have mother-son incest with Jun-seok... I'll fuck him too..."
"Of course... Your real son, born from your real brother's cum... You'll make a kid with his cum too... That's amazing."
"Yeah... and if it's a son, I'll fuck him when he grows up."
I feel blood rush to my cock.
Listening to Yu-jin's dirty talk, I can't hold back anymore.
I stand up and grab her ass with both hands.
Then I line up my throbbing cock at my younger sister's gaping asshole.
Yu-jin's waist jerks, then slumps down.
"Enough talk... Let's just fuck, Yu-jin."
"Yeah, oppa... Put it in... My asshole... Jun-seok doesn't even know about that yet..."
"Heh... Of course, there's an order... You fuck the mom-pussy first, then break in the backdoor."
I look down at Yu-jin, who's on all fours like a dog.
Before I know it, her asshole is gripping my cockhead, stretching out.
With all my strength, I shove my cock deep into my younger sister's asshole.
