Chapter Title: Sisters' Temptations
-----------------------------------------------------------------
If the eldest, Sujeong, was the reliable and warm big sister type.
Then Geumbi, the second sister, was a bit intimidating—like the strict disciplinarian of our house.
You could tell just from her usual gaze, tone, and demeanor.
Especially when the younger siblings messed up, she'd always be the first to glare and scold us.
'That's why getting this close with Geumbi of all people felt the most unreal... Not just unexpected, but something I never even dared to hope for.'
Even then, from start to finish, she was always the one in control.
Of course, the idea of her willingly crawling between my legs to suck my cock... That alone was enough to drive me insane with lust.
But deep down, a part of me wanted to rough up this arrogant sister... A forbidden desire no little brother should have, one that was slowly growing.
Call it rebellion. Or maybe some innate urge clashing with resentment, fueling it further.
'But now she's come crawling to me on her own two feet. This is all her fault. I'm a guy too—how am I supposed to hold back?'
I figured since I'd crossed a line I shouldn't with Hwayeon on my own, she'd chew me out like usual, and I'd accept it.
But seeing Geumbi bow her head, take my cock in her mouth, and fumble to please me... It shattered the walls I'd built up inside.
The dark, twisted thing I'd barely kept locked away—the filthy impulse I should never show a sister—broke free.
"Glrk?!"
"Swallow it all. No teeth—suck gently."
"Mmph, mm... Ngh! So sudden... It's too b-big."
"No whining. Open wide, nice and obedient. Open your throat too. You're just making it harder by resisting."
"Gulp... You're too much. Khk, gack!"
Under my forceful attitude, Geumbi made a pitiful face for a moment.
But her body was honest, taking my cock even deeper into her throat.
"You can do it if you try. Didn't you say you could handle this anytime?"
"Ahk... Mmph, I can take it. So... only do this with me from now on. Khk!"
"You're the only one who can handle it, so of course it'll only be with you. So if you ever want to suck my cock, just say the word."
"Whiiine... This isn't sucking, it's—gck. Swallowing it whole, kheuk."
"You wanted my cock stuffed so full? Got it. I'll shove it even deeper, no holding back."
"Mmph?! Glrk?! No, nooo! That's not what I—khk. Krrgh...!"
Geumbi whined about how tough it was, then quickly insisted it was fine and demanded I only give it to her.
But then she nitpicked again, so I ignored her words and focused on the eager plea of her mouth.
Her cherry lips parted wide, closing softly around the head as it passed.
Her gums and tongue lapped and flicked at the shaft inside.
Tears welled in her eyes, but her efforts to swallow down to the root were... blatant, instinctive. Perverted, even.
"Be honest, sis. It hurts, but you like the taste, right? Or is the pain itself what turns you on?"
"Khk?! N-No, not the second one...!"
"Hmm. They say a strong denial is the strongest affirmation."
"Mmph... Anyway, no. Really, gulp."
"Ngh!? Swallowing spit with my cock buried... Feels so weird. Driving me crazy."
"Mmmph... You like this? Lick, slurp, gulp."
"Ahk, this sister of mine...!"
"Hehe, you love it? Slurrrp, smack. Looking up from below... Makes me feel weird too, smack."
"Hoo, adapted to the pain already? While sucking your little bro's cock like it's playtime... Ahk."
"Smooch, smack. Not playing. It's tough, but I'm doing it for you, slurp."
"Ngh. How is this 'for me'... Ya. Now you're sucking it outright, kuh."
"Slurp, smooch, khk! Phew... Hek. I only do it 'cause you like it. Slurrrp, smooch."
I tried mounting her, thrusting into her throat to dominate.
But her lips and throat squeezed me just right, her skillful moves stealing control back in no time.
Or maybe I never had it to begin with.
Even when pinned beneath me, whimpering, her body twitched with arousal.
'Where did that goblin-like fire from before go? Look at this face—how is this Geumbi? She's just a cock-crazed slut now, ahk!'
Giving no respite, she tightened her lips with every breath.
The wet smack smack echoed through the room. I tried holding back my pathetic moans as a last stand of pride.
But now fully accustomed, Geumbi gripped my thighs and bobbed her head solo.
No way I could endure that. Hell, I was the one who should beg.
"Sis, Geumbi sis... Ahk, sucking like that from below... Blood rushing down... Ngh."
"Slurrrp, smooch, phew! Feels good? Riding your sis, shaking her around? Smooch, smooo ch... smack! Hehe."
"Maybe at first... Now it's all you, ngh. Aaah, yes! Good, so go easy a bit, hng?! Sis, siiis...!"
"Sluuuurp... No, don't stop, smack. Looks like you all love it rough, so let's enjoy. Since we started, I'll go all the way... Khk, cough, cough!"
Round and round, I finally got Geumbi to confess her perverted tastes with her own mouth.
But somehow, it ended up 180 degrees from my original intent. Like turning her choking gasps under me into her own eager deepthroating.
Of course, either way, it felt incomparable.
The heat and blood surged below. I grabbed Geumbi's head, yanking her face to my groin.
"Glrk?! Cough cough, khek?! Mmph, mmrph... Kerrrk!"
She coughed once when I thrust deep, once as it twitched inside, again when the tip poked her uvula.
The relentless stimulation broke me. I unloaded straight down her throat again.
"Ngh, Geumbi sis... Ah, haa."
"Mrrph?! Cough cough, kerok. Glrk, phbt! Krrp...... Gulp gulp, guuulp."
Maybe too rough, too deep—Geumbi smacked my thighs, eyes tearing up.
But my cock stayed buried. Finally, she swallowed it all down with her saliva.
"Haa, Geumbi sis... That was the best. Ngh."
"Mrr, hek...... Pervert. Cumming so much inside me, you idiot... Whine."
Her face showed more strain than usual, probably the position.
But she didn't skip cleaning my cock with her tongue. As it softened, she licked her lips regretfully.
"Ahk, anyway... Try this with anyone else, and you're done. You'll get sued and locked up, got it?"
"Then you'll have to take it all your life. From now on, only inside you."
"...Yeah, cum only inside me. Spit in anyone else, and I'll kill you. For real. Haa."
Finally reverting to her usual tone at the end.
But the words were vulgar as hell. She blushed furiously, embarrassed by her own mouth.
I gently stroked her warm cheek.
She purred like a content cat—nothing like the Geumbi I knew.
'That's why... weird thoughts keep creeping in. Imagining doing all sorts of things to her, hoo.'
People think how they act, and act how they think—I felt it firsthand.
We made a promise too shameful for paper, not even verbal: No cumming inside anyone but Geumbi.
After, she fled to the second-floor bathroom under the pretense of brushing her teeth.
I bolted to the shower for the same excuse.
My groin still burned hot, wanting more.
But it wouldn't match her hot lips... or face. So, cold water to cool off.
Of course, as if scripted.
The more water I poured, the hotter my heart pounded.
"Calm down, calm down. Haa, what the hell am I doing, Jigu Yang...?"
I repeated my name, replaying yesterday and today's events.
Hwayeon's pussy, Geumbi's mouth. As a big bro, as a little brother—total failure. My face burned late.
"Agh, seriously. Gotta get my head straight now."
"Oh? What happened with the kids while I was gone?"
"What happened? It'd take all night to explain... Whoa?! S-Su, Sujeong sis?"
For a second, I thought I forgot to lock the changing room door again.
But shower water hit my head—this was definitely inside the bathroom beyond.
The frosted glass door should've shown someone was in.
Sujeong strode toward me without a care.
...For some reason, perfectly matching the bathroom vibe: not a towel on her skin.
"Hng?! W-Wait, why are you naked...? More importantly, sis, I'm totally nude too... Ngh!"
Seeing Sujeong naked up close wasn't new.
But the mood was different now. Where Geumbi had been uncharacteristically hesitant, Sujeong pressed firmly against me.
"Time you got used to it, right? You've been eyeing my body plenty."
Under the bright light, she placed one pale hand on my chest.
I couldn't dodge or even think to—lost in her slender hand and porcelain nude.
"Since I'm showing it all... Can I check one thing?"
"W-What?"
"Jigu... Have you ogled Hwayeon or Geumbi like this?"
"Ngh?!"
Swish. Her hand slid below my chest, below my navel.
Lower still, only my wilted beast remained.
Drained on the bed, it twitched up and down under her gaze.
"Did their bodies get you this hard? Jigu?"
What to say?
Unlike with Geumbi, I swallowed hard, mouth shut.
Seeing my throat bob, Sujeong... shifted her fingers to my thigh gap, near my groin, and pressed her full breasts against me.
