Chapter Title: Little Sister's Face
-----------------------------------------------------------------
Until the heated atmosphere finally cooled down, Geumbi sis and I spent the time in a quiet lull.
That didn't mean we avoided each other's eyes in awkward silence—no, we kept up a calm conversation, stealing glances at one another.
"Jeez. Lately, everything you do feels so pervy, Jigu. That's why I keep calling you over here out of worry."
"Pot calling the kettle black, huh? You're the one who does weird stuff every time you call me."
"Weird stuff? I was just scolding my little brother as a proper big sis should."
"Then what's this hand doing right now? And shaking it like that—is that part of the scolding too?"
"I already scolded you plenty earlier. Now I'm just soothing you so it doesn't hurt, you idiot."
Thanks to the natural chit-chat, the heavy air lifted, but Geumbi sis's hand nestled between my legs stood out like a sore thumb.
Still, she showed no signs of stopping even if I pointed it out directly, and me... well, it wasn't something I hated enough to actively stop. So I decided to let it slide.
'Anyway, I need to clearly back off once for Geumbi sis to feel reassured. Otherwise, she'll stay on guard, thinking I'll go after Sujeong sis again.'
It was a ridiculously tangled misunderstanding, but unraveling it now would only complicate things more.
I shoved the headache-inducing worries aside with the passing air and decided to enjoy the sensation between my legs for a bit.
'Nothing cools the head quite like this. Geumbi sis seems calmer too, so let's help each other out—good for sis, good for bro.'
...Hmm. It's a fitting proverb, but it feels kinda off.
Maybe because it's not sis and bro-in-law, but sis and little brother.
Brushing off the triviality, we continued our conversation in the same position anyway.
Geumbi sis softly stroked my dick, using the excuse of making sure I wouldn't lust after Sujeong sis and soothing the earlier torment.
Her touch was scary when she was threatening me, but otherwise, it felt incredibly good.
"But man, this thing's always so full of energy no matter when I look. After all that shaking, shouldn't it be wilted by now?"
"You think it's some touch-me-not plant? It doesn't just flop over from a little shaking."
"Keep shaking it long enough, and it flops at the end anyway."
"That's... after it cums. It doesn't usually die before then."
"Back when we first did this, you said it'd go down on its own if I just left it alone."
"That was with no stimulation. You think it'll go down when you're nonstop groping it like this?"
"Hng~ So it feels good enough to hold out, huh? At least that much, hmm."
As the interrogation tapered off, the topic shifted to the obvious thing right in front of us.
Geumbi sis meticulously stroked every inch of my shaft, half-lidded eyes narrowing as she asked.
"But it still wasn't good enough to fully satisfy you, right? Hmph."
"What? When did I say th— Oh."
"Forgot already? You said it yourself, Jigu. My handiwork's so sloppy and amateurish, you couldn't be satisfied at all~."
"I didn't say it quite that harshly... Did I?"
"You totally did. That's why you went scampering off to Sujeong sis instead."
"No, no, that's a total misunderstanding. It wasn't for that reason... Agh?!"
"Now that I think about it, it pisses me off. Breaking your promise and touching sis is one thing, but how bad was it that you ditched me without a word? Huh?"
"S-Sis. Squeezing that hard hurts... Ow."
"Oops, sorry. As you know, my hand skills are just so~ clumsy."
Thankfully, her anger over me touching Sujeong sis had mostly subsided.
But now, she seemed pissed about me choosing Sujeong sis over her instead.
'No point yelling that it's a misunderstanding—she won't even listen. Time to clap back like earlier?'
From experience, innocent apologies only backfired with angry Geumbi sis.
Maybe because she's such a hardcore Type T, she paid more attention to logical counters even if they contradicted her.
Time for some payback on the injustice—I pointed it out a bit harshly.
"Honestly, you're not that great at it."
"Hng?!"
"Not saying it's bad or anything. It's just inevitable. You said you've never even dated, right?"
"Wh-Why bring that up? Annoying jerk."
"Gotta identify the root cause to fix the problem."
"...Mind your own business. And 'you too'? You're comparing me to Sujeong sis again, aren't you?"
Her bristling reaction meant I'd hit a nerve spot-on.
Good, now she was paying attention—I gently steered the flow my way.
"That's not the point. I just mean you don't know yet, but you're good at everything, so you'll pick it up fast once you learn."
"Hmph, buttering me up late. So what's your conclusion? Should I study porn alone or something?"
"That's one way, but there's an easier method."
"What?"
"I'll teach you. We've got the perfect teaching aid right here—how to touch where and how for maximum pleasure."
"...You're telling me to learn how to handle a guy's dick from my little brother?"
"We're already doing something similar. Plus, you asked me how to make it feel good."
"Th-That was because you talked so crudely! I only asked in the heat of the moment..."
"But you weren't totally against it, right?"
"Ugh... Urgh..."
Geumbi sis was the type to say yes or no clearly.
Lips pursed like that meant it was true, but she hated admitting it.
'So honest even about this. Heh. She used to seem so bold, but lately she's coming off kinda cute.'
Like a kid sulking in front of her parents.
I reached out and patted Geumbi sis's head.
"Wh-What're you doing? How dare you pat your big sis's head..."
"Dodge if you hate it. Besides, you've got my precious part in your grip—tit for tat."
"How's this tit for tat? You love me touching it."
"Then like me patting you too. Problem solved."
"...Bullshit. There's a limit to forced logic."
Geumbi sis grumbled but didn't swat my hand away or dodge to the end.
I smiled softly and slowly slid my hand down to wrap around the back of hers gripping my dick.
"Hn?!"
"I'll guide you directly. You'll learn faster this way, right?"
"...What's so great about learning this crap quick?"
"Want it slow then? I'm good either way."
"...Perverted bastard. If we're doing it, hurry up and finish. That's better."
"Thanks for the feedback. Keep it up."
Learning's more about the student's attitude than the teacher's, after all.
In that sense, Geumbi sis was a perfect student—honest reactions, emotions, feedback, A+ material.
"When you first grab it or when you're excited, your fingers squeeze too tight. That spikes the stimulation, killing the build-up."
"...Build-up meaning that... white sticky stuff?"
"What's white and sticky?"
"You know better than me... Don't ask."
"Better to make the student realize it herself than rote lecture."
"Don't quote eduphorisms here. Feels like you're corrupting our nation's education."
"Corrupting? This is sacred learning for smooth male-female relations."
"Sacred my ass—it's vulgar. ...And I have zero interest in smooth relations with you."
"Really? I'd like that."
"Hik?! Wh-What? Hey, that's crossing the line...!"
"See? You tensed up from surprise. That's exactly what not to do."
"No, that's because you... Urgh, tch!"
Geumbi sis scowled like she'd taken a hit and whipped her head away.
But her hand adjusted strength and speed to match my movements, and whether by talent or smarts, she quickly hit the right rhythm stroking my dick.
"Ugh, yeah. Just like that... Remember it well."
"Remember what? I'll forget it right after today. What's the point memorizing this?"
"Heh, so you'll remember till then? Why? Gotta touch me here again?"
"D-Don't say weird stuff. Just... rubbing it now, so it'll stick in my head."
"Yeah, good enough. Let's take it step by step."
"Tch. Beating your own drum and all, throwing a party by yourself."
"You're the one holding and shaking the stick."
"Uh... Huh?! Your mouth's getting bolder? That's sexual harassment."
If I'm a harasser, isn't she an assaulter?
No matter how you slice it, the sis grabbing and shaking her brother's dick looks worse than the brother talking smack.
'She knows it too—shuts up quick after one retort. ...Speaking of mouths, it felt amazing when it brushed her lips underneath.'
Teaching pleasure techniques naturally replayed that thrilling memory in my body.
And watching her pout, grumble, gape, then clamp shut right in front of me... I couldn't not think about it.
"Mm, sis."
"What now."
"Hand stuff... this is good enough."
"And?"
"...Rubbing raw skin stings a bit. Lube would be nice."
"Like lotion or gel? ...You put that on here?"
"Anything for skin's fine. But something we can use right now would be best."
"Right now? All my cosmetics are in the drawer... What? Why stare at my face?"
"Could you... wet it with some spit?"
"Eh? ...Eek, what?!"
Zero experience in this area, maybe? Geumbi sis freaked way more than expected.
But with my dead-serious pleading eyes, she glanced between my crotch and face, puzzled.
"S-Spit? My spit? You... spit that on here?"
"Yeah, it's pretty common. Saliva mixes during kisses too."
"Sure, but... down there? Never heard of it."
"You're so innocent, sis. Adorably so."
"Urgh?! D-Don't say that to your sis. Gives me chills."
"So, can you?"
"...I'm doing it 'cause you say it hurts like this. How?"
Geumbi sis flushed and brought her face close to my dick.
She could've just spit on her hand or hocked a quick loogie, but I lifted my twitching dick.
I gently stroked and rubbed her panicked cheek.
"Hn?"
"Lower your face a bit, bring it close."
"Wh-What? What if it touches?!"
"I'll be careful. But it's spit—wanna drip it on the bed?"
"Ugh... L-Like this? This close?"
"Yeah. Now let it drool down... onto the shaft and your hand."
"Ahh, is this really normal? Haa... *chuuup, blerrp.*"
Geumbi sis dropped her shaky pupils downward, worked her lips, and drooled a long string.
It fell about 10cm, soaking her hand wrapped around my shaft via the head.
That alone zapped my brain with pleasure.
'...Nah, not enough. Really want her to suck it once more...'
Her lips so close her breath teased, heart pounding if I bucked my hips just a tad—
Geumbi sis eyed me like "that enough?" lips parted, pupils rolled up.
That moment, an AV scene I'd seen recently overlaid reality, forcing out my held breath.
"Urgh, hngh!"
"Kyaa! What, hik?! Is this... cum? Kyaaah!"
For reference, model student Geumbi sis kept stroking through it all.
Honestly, my dick was at its limit even before the lesson—it erupted without warning.
Straight onto Geumbi sis's face, a mere 10cm away.
After holding so long, the forceful jets painted the air, inevitably landing on her nearby face.
"Yahh, y-you... Jigu! You bastard!"
Geumbi sis squeezed her eyes shut at the sudden bombardment, at a loss.
I, mesmerized by her flushed skin blanketed white... spoke without thinking.
"You're pretty. So pretty. I love you, sis."
"Hngh?! Wh-What? Are you insane?! What nonsense in this situation...!"
"Dunno. Just felt like I had to say it."
"Ahh, damn... Think I'll let it slide? Get tissue NOW! After I wipe, you're dead!"
I'd praised her honestly, but got fury and curses in return.
Knowing my fate, I gladly fetched the tissues for Geumbi sis.
And about 30 seconds later.
I got absolutely pummeled by Geumbi sis—nearly to death.
For reference, it wasn't slaps, but tight fists.
"Still hurts... Urgh. Why the hell did I do that? Sigh."
The back-ripping pain lingered into the next day.
It patched things with sis on a razor's edge, but the nagging unease made me shiver in the warm bath.
'Kept the Sujeong sis thing secret in the end, and barely scratched Geumbi sis's true feelings... Whew.'
Misunderstandings piled up till we'd gone too far.
The past issues were bad, but solving them wouldn't magically reset things with my sisters.
'Best shot at improvement... pick one after all?'
I'd ignored it, but the core problem was being tangled with both.
Sticking to one would make it easier to not cross lines.
'If so... which one?'
Sujeong sis baring her voluptuous body in front of her brother.
Geumbi sis gripping her brother's dick and rubbing without hesitation.
Tough choices both—agonizing till the bathwater cooled.
"Frustrating. Wish I could consult someone."
I got why my sisters dragged me into their troubles.
And I needed someone to hear me out too.
Finishing my morning shower, who should appear at the bathroom door but the perfect someone.
"What, oppa already showered? What's up with the early wash?"
"...Hwayeon, you heading in for a shower?"
Hwayeon looked tousle-haired, ponytail sloppy, yawning with sleepy blinks—class canceled again, probably.
"Yaaawn~ Nah. No plans out, so just rinsing my hair. Why?"
"Got time? Wanna talk."
"'Bout what? Important? Oh, I had something to ask you too."
"Perfect. Mind if I come to your room later?"
"Huh? Need to come to my room?"
"If not, no biggie. But if you do... I'd appreciate it."
"Hmm, come in 15? Done by then."
"Got it. Be there on time."
Dunno what hers was, but good timing since she had something for me too.
I toweled my damp hair, organizing how to broach my story.
