34. Siblings' Agreement
We'd achieved the climax we'd been aiming for, but Geumbi noona and I couldn't tear ourselves away from the bed for a good while.
I was lost in post-nut clarity, my mind blank.
Geumbi noona seemed frozen solid, overwhelmed by the feel of a cock in her hand for the first time and the sensation of semen.
'...What the hell do we do now?'
Once my ragged breathing steadied and my pounding heart settled back to normal, my melted brain finally started working again.
I naturally slid the hand that had been stroking Geumbi noona's head down to her back, half-embracing her as I stole a glance at her face.
"Eek...!"
Our eyes met, and Geumbi noona hurriedly looked away.
But her body stayed pressed right up against mine, and she looked too embarrassed to even think of moving.
It was so cute I nearly reached out to pet her head again.
But I barely clung to my sanity and, belatedly, confessed to Geumbi noona.
"Actually... I jerked off in front of Sujeong noona yesterday."
"Huh? W-what?"
"You were curious, right? About what happened between us last night."
Geumbi noona's eyes went wide at the sudden confession, but then she remembered her forgotten interrogation and her gaze sharpened fiercely.
"So, you really are in that kind of relationship with her now?"
"What do you mean 'that kind'?"
"You know... like dating, or something similar..."
"Noona, we're siblings. How could family date or be lovers?"
"Urk?! B-but it could happen! You or Sujeong unni might be adopted or something."
Geumbi noona's guess had some logic to it.
Even I had fantasized last night, wondering if Sujeong noona wanted to marry me or something.
'But nah, probably not. We're not kids anymore—if she was serious, she'd have picked a better way than that.'
It wasn't like we were horny high schoolers who thought seduction would work.
More importantly, we still didn't know for sure if we weren't blood-related. And even if we weren't, there was no real reason to date my sisters.
"I think Sujeong noona just doesn't want to break the family mold."
"...What're you talking about all of a sudden?"
"We've ended up suspecting each other by accident, but we've always relied on one another, so these thoughts keep popping up. With Sujeong noona, and now with you too, Geumbi noona."
"...Yeah, that's true."
"So she's probably anxious. Worried that if I keep this up, we'll cross a real line someday... and she's stepping in to control it herself?"
"And her way of doing that is watching you jerk off?"
"...She didn't just watch, though. Ahh?!"
In the midst of my belated confession, I dropped another bombshell even later.
Geumbi noona pinched my chest hard with her free left hand, her eyes blazing.
"So what did you do to unni? Or did she do something to you?"
"N-no... She really didn't touch me. I swear."
"Then?"
"...She just took off her top and hugged me... Ungh."
"Took off her clothes? Sh-she showed you her bare skin?!"
"I didn't see it properly. She turned around to undress and hugged me right away."
It was true.
Sure, I'd snuck a peek at her side boob in the mirror, but that was it. Borderline okay, right?
Nope, apparently not.
Geumbi noona's glare from below was terrifying.
"Anyway, so you came in unni's pants too? With the smell all over them?"
"...Yeah."
"Hah, now it all makes sense. Yeah, that's the smell. The one wafting from your crotch right now... that night-blooming flower scent."
As Geumbi noona pulled her hand out from my pants, the undeniable evidence spread across the bed.
She sniffed, wrinkled her nose in disgust, and ground her molars.
"You two really... You're both insane."
"...Sorry, noona."
"Don't apologize. That just makes it sound like we're in some weird relationship."
I couldn't deny that.
A sister playing dick warmer for her brother jerking off at midnight? Not normal, by any stretch.
'Though a sister handjobbing her brother during an interrogation isn't much better...'
For now, I shut my mouth.
I didn't want to compare the two sisters, and saying it out loud might get my dick held hostage again.
With both of us silent, the bed fell quiet once more.
But this time, we weren't just spacing out—we were both deep in thought.
"Noona."
"Jigu."
"Oh, yeah. You go first, noona."
"No... it's fine. You say it first—what is it?"
Our timing overlapped perfectly, and after hesitating, I made my declaration to Geumbi noona.
"I have zero intention of crossing any lines with you sisters."
"Hm?"
"The situations led to misunderstandings, but if I'd wanted that, something would've happened ages ago."
"...True. Just look at Sujeong unni—if you'd had bad intentions, that situation could've been super dangerous for her."
"Exactly. The fact that nothing happened proves I don't think that way."
"So? What's your point?"
"From now on, I'll be extra careful so nothing like this happens again. That's it."
I couldn't think of anything else to add.
You can't prove something like this with evidence or a written pledge.
But maybe my past actions were holding me back.
Geumbi noona nodded, but her response made it clear she couldn't fully trust me yet.
"We've lived as family our whole lives, and even if we're not blood-related, I don't think our relationship will change."
"Yeah."
"But that's separate from whether I trust you right now."
"Uh-huh..."
"Stuff has happened, and who knows when more accidents might pop up."
"...Can't I just promise to be more careful?"
"At this point, words alone aren't enough."
She had a point.
Honestly, even I'd find it ridiculous if someone came in my hand and then spouted promises like that.
"Or... what if we go back to sleeping separately like before?"
"Each in our own rooms? You think Sujeong unni would agree?"
"...Dunno. After what she did last night, she still seems to want to sleep together."
"Right. If sleeping apart fixed it, she wouldn't have done that. ...Same for me."
"Huh?"
"It was fine when I didn't know, but once we tried it... it's comfy and nice. For now, I wanna keep going like this."
With both sisters feeling that way, separating physically wasn't an option.
I had no more ideas, so I scratched my head and asked about what Geumbi noona had been about to say.
"What were you gonna say earlier? We overlapped, so you held back."
"About this issue... I'm good with everything, but one thing I can't compromise on."
"What?"
"Don't touch unni. I won't allow that, no matter what."
Geumbi noona looked up at me with eyes full of pure resolve—not anger, panic, interrogation, or surprise.
Her gaze, her voice, the words themselves all conveyed how dead serious she was.
"I don't know exactly where your 'line' is... but from my perspective, I wish nothing like last night had happened between you two."
"Yeah... I get that."
"Of course, I understand unni's feelings. But... it's impossible. No matter how I think about it, I can't stand seeing you and unni get tangled up like that."
"Yeah, I understand completely, noona."
Geumbi noona had always adored Sujeong noona fiercely.
Even when they fought, it was always out of worry for her—Geumbi noona's heart was steadfast.
'It's not about blood relations or not. Even I'd feel gross if Sujeong noona got with some random guy.'
Honestly, it'd be revolting.
It might be selfish, but I'd prefer if Sujeong noona never knew a man her whole life.
'Sigh, I'm still such a kid. Gotta grow up and graduate from big sis already...'
I felt pathetic for relating to Geumbi noona in such a weird way, and noticing, she blushed.
"Got it. So I'll be extra careful around Sujeong noona, right?"
"...I said words alone won't reassure me."
"Right, yeah. So what do I... Ugh?"
We'd reached a mutual understanding and comprehended each other.
We'd walked the same path analyzing the situation and the problems—
But at the final conclusion, Geumbi noona pulled ahead.
"N-noona? Your hand right now..."
"That's why, if you're okay with it, Jigu... I'll take care of everything from now on."
"Huh?"
"Whenever you're struggling, whenever you get hard, I'll handle it for you. ...Wouldn't that work?"
An astonishing proposal.
No, a jaw-dropping, heart-stopping one.
'After hearing everything about Sujeong noona, that's your conclusion? For real?'
What made it different from Sujeong noona's offer?
It was absurd, but facing Geumbi noona's earnest expression, I couldn't spit out a refusal.
"...Only if you're the one leading it, right?"
"Yeah. Just my hand moving to take care of it... no problem at all."
Without thinking, I'd tossed out a question that sounded like agreement.
I'd tried not to compare, but the similar situations forced me to weigh the two sisters.
'Not emotionally—just objectively, which proposal is safer.'
Sujeong noona's was to use her body as bait.
No direct contact needed, seemed safe—but last night, I'd ended up hugging her anyway.
'Whether we cross the line depends entirely on my self-control.'
Geumbi noona's, on the other hand, was direct handjob assistance.
More skinship than Sujeong noona's, but Geumbi stayed fully clothed, and she held the reins.
'Even if I lose it and try something, Geumbi noona would definitely stop me.'
The scales tipped slowly.
Comparing their appeal was nonsense, so I chose the option that seemed safest situationally.
"Then... can I ask you from now on, noona?"
"Yeah. And I'll... tell you whenever I get excited too, Jigu."
Only after exchanging those words did we realize what kind of pact we'd just made.
Without deciding who went first, we both flushed crimson and sputtered excuses.
"O-oh, wait, of course not every time! Only if it happens, and I'd never ask otherwise."
"Y-yeah, obviously. I'm not saying I'll do it anytime, either? Haha...!"
Looking back, maybe I should've stated more firmly that nothing like this would happen again.
Regrets always come too late, and the past can't be changed.
Just like the flushed cheeks of those siblings, or the sky dyed red that eventually turned pitch black.
Once things started changing, they wouldn't stop—they'd only march forward.
A few days later, Geumbi noona came home from work and quietly called me to her room.
As we chatted casually like usual, my lower half unexpectedly stiffened.
I'd managed to hold back and abstain for about three days.
But at the accidental brush of Geumbi noona's hand, it reacted on reflex.
"No, noona, this is..."
"...Want me to help, Jigu?"
It was barely a twitch, hardly a full erection.
But Geumbi noona didn't miss that tiny response and asked me directly.
I definitely had words on the tip of my tongue.
But my trembling lips... never made a sound until her hand slipped into my pants.
