Geumbi's palm enveloped my groin.
It wasn't quite a grip, but more than just laying her hand flat—her ambiguously curled fingers brushed lightly over my crotch, back and forth.
"Ah, oof."
"Hn…!?"
I tried to stifle my groans, but little sounds slipped out now and then.
Each time, Geumbi's eyes twitched, but even as she gulped down saliva with audible swallows, her hand didn't stop.
I felt like my mouth was drying out to the point of cracking from lack of moisture.
And Geumbi seemed to be in the same boat—swallowing sounds kept coming nonstop from under her chin.
'How the hell did things end up like this? Ugh.'
There were probably more than one or two reasons if I traced it back.
But for a brother and sister living under one roof to reach this point, there had to be some decisive trigger.
'Does Geumbi really think she's the adopted one? Or… does she think it's me?'
Otherwise, she wouldn't go this far with her own blood sibling.
The rest was probably excuses like doing it for the family, emotions swept up in the mood and flow, and her innate curiosity about a guy's body.
'Her fingers are probing deeper and deeper. Like she really wants to touch it.'
At first, she'd only grazed it teasingly with her palm, barely making contact.
Before long, though, Geumbi's hand was cupping the swollen space between my legs, her fingers wriggling and rubbing bit by bit.
'If she just squeezes a little harder, she'd feel the shape… but maybe that's still too much for her?'
The vague bulge almost formed a clear pillar shape in her hand, but right at that moment, Geumbi eased off and went back to rubbing.
"Jigu."
"Y-yeah."
"Does it… feel good? Is this okay?"
"Ah, yeah. Feels… amazing. Keep going."
I was completely focused on her touch when Geumbi quietly spoke up.
Maybe embarrassed about doing this on the bed, she kept avoiding my eyes to the end.
But once she opened her mouth, the awkwardness faded a bit compared to before.
"As long as you like it, Jigu. Tell me if it hurts."
"Doesn't hurt. If anything, it's so good it's… kinda dangerous."
"Th-that much?"
"No one's ever touched me like this over my clothes before."
This wasn't even common in a lover's relationship.
They'd sooner strip naked than climb onto a bed and patiently rub just that spot over pants, right?
So this was something only possible in our special relationship.
A fateful touch, barely achieved because of the line we siblings weren't supposed to cross.
'When I put it like that, it sounds so grand. Better not say it out loud. Too embarrassing.'
I swallowed the ridiculous words and mustered the courage to look down at Geumbi.
Our eyes met—she'd been looking up at me, too.
"Ah, uh."
"Ugh, h-ha…!"
I couldn't even call her name, and neither could she.
With shallow breaths, Geumbi hid her flushed face, and I could feel the heat of her skin radiating from where her head rested against my chest.
"Wh-why are you hiding your face…."
"B-but… it's embarrassing…."
If I backed off here, we'd fall silent again, so I barely kept the conversation going.
Geumbi couldn't lift her head, but she didn't dodge the reply either. We fumbled through words while tangled on the bed.
"You're the one… doing this with your own hand. And you're embarrassed."
"Y-you're the one doing dangerous stuff, Jigu… I'm just worried, that's all."
"What'd I do? I haven't done anything yet."
"You said 'yet.' See, if I left you alone, Sujeong sis would definitely be in danger."
"That was a slip. I told you, I don't think like that about family."
"……Then what about me?"
In the middle of my chatter, Geumbi lifted her head again.
That instant, I realized my real slip-up and hurriedly corrected the words that could sound weird.
"I-I didn't mean you're not family, sis."
"…So that means you're different, Jigu?"
"No, that's not it either. Agh, what I mean is…."
"If it's neither, then… what does it mean?"
I'd cleared her suspicion about herself, but now the arrow pointed at me.
I deflected that too, and she dug straight into my heart, demanding the truth.
'Harsher than a dilemma. Whatever I say, she'll grill me… damn it.'
I picked the option where no one got suspected.
"It's 'cause I'm a pervert, like you said."
"Wh-what? Huh?"
"So even with you as my partner, it feels weirdly good. Let's leave it at that. Conversation over. Okay?"
"No, uh, I see. You can feel that way even with your real sister…."
"I said it's over. Why keep bringing it up, sis?"
"S-sorry. It's just… kinda shocking…."
Yeah, it would be.
Even I thought, what kind of pervert nonsense is this, after saying it.
'To dodge her suspicion, I turned myself into the pervert… I wanna die. Anyplace to jump from?'
Conveniently on the second floor, so opening the window and leaping would do.
Hmm, too low? Might have to climb to the roof later.
"Ugh, kuh. Sis?"
"Ah, sorry. I got flustered for a sec… sorry."
Lost in my despair, a strong pressure hit my lower half.
Geumbi had unconsciously gripped hard, then startled herself and quickly let go.
But… hmm.
Honestly, it didn't feel bad.
"Hey, sis."
"Y-yeah, what, what is it? Jigu…?"
"We can't just stay like this forever. You've gotta head to work in the morning."
"Oh, right. But… it's not going down at all."
"That's why—could you grip it tighter, like before?"
"Wh-what? Grip it… tighter?"
"Feels like it'd finish quick that way… N-never mind if it's too much! Sorry, I got ahead of myself."
Desperate to escape this spot and the lingering good sensation mixed in, I spouted nonsense.
I snapped back and waved it off, correcting myself….
"Jigu."
"Yeah, really sorry. I just blanked out for a second…."
"If I do that, will it really… finish?"
"Huh?"
"No, but… you have a point. We can't keep this up forever, and I need to get to work… might as well wrap it up."
Geumbi said that, glancing down at what her hand held.
At the same time, her throat bobbed as she swallowed hard—it was obvious what kind of "finish" she had in mind.
"……Can I…?"
"……Just this once."
Seeing my shock seemed to snap her back; Geumbi belatedly added the "today only" condition.
But that also meant she'd go all the way today.
Soon, her hand seized my crotch and began a sticky, slick pistoning motion.
"Agh, ugh."
"Does it hurt? Tell me right away if it does."
"Nah, it's good now. Perfect, actually."
"Ah, okay… this is the right amount…."
Geumbi muttered as if memorizing the pressure and speed.
I couldn't hold out against her words and movements, twisting my hips.
"Ugh, sis, Geumbi sis…!"
"Haht?! Ah, ah, uwaaah…."
With Geumbi on top, my body couldn't buck much.
But the pillar between my legs… shook like an earthquake, soaking my underwear and pants wet.
"Haa, ha, haa… haa."
"Ah, d-did it… finish? This is… it, huh."
Even after I came, Geumbi kept her hand on my pants for a while.
Luckily, the pants weren't thin, so no liquid seeped out, but the lukewarm warmth—and her trembling hand—told the story.
'I really… came from Geumbi's hand.'
My hazy mind cleared completely.
Geumbi's eyes regained their normal spark, too.
We turned our faces away again, mumbling awkwardly like babies.
"Uh, th-that was… good job, Jigu. Thanks for following my lead. Must've been tough."
"No, sis, thank you. Must've been super awkward for you."
"N-no, it's fine. I was kinda… no, nothing."
"Got it. ……Can I go wash up now?"
"Ah, of course…! G-go wash up quick, Jigu."
The awkward vibe could've filled books between us.
I escaped the suffocating space on the shower excuse, and Geumbi hurriedly got off me, untangling our bodies.
Our nighttime play seemed over—but.
"Oh, but hey, Jigu?"
"Yeah. What, what is it?"
"After you wash up, you're going back to your room, right?"
"Uh, yeah, obviously? Why?"
"Just… I don't want you to."
"……Why?"
We'd settled everything—talks we had to have, questions to vent, precautions for what-ifs.
Yet Geumbi held me back, and I couldn't bolt.
Maybe I never wanted to run in the first place.
"Just… 'cause. Tonight… with sis here, stay, okay?"
"……Then where do I sleep?"
"……My bed's pretty big. And tonight feels kinda lonely anyway."
With that, Geumbi tossed her hair and turned her head away sharply.
But her eyes kept flicking back, and I fiddled with the doorknob slowly, chewing my lip.
Finally, the locked door clicked open.
The moment I headed downstairs to shower.
"Be right back. Sleep if you're tired."
"Ah, uh, yeah! I'll wait up…!"
"I said you can sleep first… alright."
Click.
I shut the door softly since it was nighttime.
Showered, changed, confirmed Sujeong was sleeping soundly, then headed back up the stairs.
About ten minutes passed? Maybe Geumbi was already asleep—I'd quietly return to my room if so.
"Ah, y-you're back? Pillow… this okay?"
Geumbi leaned against the bed's headboard, hugging a pillow to greet me.
No lights on in the dark, her bright eyes waiting for me—and gazing at her,
"Just for tonight."
"Yeah, just tonight… right."
I echoed her earlier words back.
She repeated them too, lying down with a mix of relief and joy.
…Why suggest sleeping together if that's the case? A mystery.
But Geumbi doted on Sujeong so much, maybe prepping for "just in case." I settled on that.
'Come to think of it, why'd Sujeong drink so much when she doesn't usually?'
The thought of Sujeong alone in the room hit late, but seeing her asleep, I pushed late-night worries aside and closed my eyes calmly.
Unlike with Sujeong, Geumbi and I lay back-to-back, not facing each other.
Still… the pounding heartbeats kept the room hot all night.
