Chapter Title: Eldest Sister's Breasts
-----------------------------------------------------------------
The changing room lights were a dim orange glow.
It was just a place to swap clothes, so I'd never felt any real inconvenience before... but right now, I resented them fiercely.
It wasn't because they were too dim.
On the contrary, that soft lighting made her skin look even more alluring.
'Her whole body looks flushed red... No, is it actually red? Nah, no way... Ugh.'
My back was pressed against the wall, and with nowhere else to look, she had me cornered.
Sujeong (Eldest Sister) had come all this way, only to blush and cast her eyes downward herself.
But those occasional sidelong glances my way, the breast flesh she couldn't fully cover with her arms, the jiggle of her tits every time she twitched... It was driving me insane. There was no other way to put it.
'Even if she's my blood sister—or maybe not—anyway, this is... problematic. Sigh.'
I finally lifted my head and let out a deep breath.
I thought that might calm me down a bit, but when I lowered my gaze again, the look in her eyes made me reach out without thinking.
"Eek?!"
"Ah, no. I was just gonna scratch your cheek."
"Oh, got it... Sorry."
It was a lie.
If she hadn't reacted, my fingertips would've brushed her skin without me realizing.
She seemed to know it was a close call, yet she bit her lip apologetically toward me.
I bit mine harder, tasting blood, and asked her.
"Why... are you going this far?"
"Huh?"
"Even if there've been a lot of misunderstandings lately, this feels too extreme."
I acted like the innocent little brother cornered by his aggressive sister, feigning confusion about why she was doing this.
...It was an act because my real thoughts were the total opposite.
Like I couldn't hide my true feelings, my eyes were blatantly devouring the cleavage of her breasts, unlike my words.
Sensing my gaze, she clutched her arms tighter around herself.
But she didn't blame me for it, instead stumbling over her words as she gently poured out her heart.
"I want us... to stay family forever."
"We already are."
"But now, we might not be."
"Noona, if one of your siblings isn't blood-related, would you stop thinking of them as family?"
"That's not what I mean! But... things might not stay the same as before. For the others, or even for that person themselves."
She wasn't wrong.
From my perspective, if I suddenly learned one of my two younger sisters—or wait, no, one of the siblings—wasn't blood-related, I couldn't say our relationship wouldn't get awkward.
"Plus, Mom mentioned Dad's will and stuff. That'll naturally bring up inheritance and dividing assets."
"...Maybe it's all those real-life TV shows lately. I can't picture it going well."
"Of course I don't think you'd fight over that. But... as your big sister, I can't help feeling anxious, right?"
I got what she meant.
When it was just her under suspicion, she'd come to my room and sleep with me to calm down.
But as Geumbi (Second Sister) and I started looking suspicious too, her imagination ran wild and her heart raced.
Yeah, I get that much.
I understood it all.
"So your solution was to get in a relationship with me? If we're not siblings, marry and make it official as family?"
"Eek?! W-what are you talking about? How could family marry each other...?"
"I imagined it before. Otherwise, I can't figure out why you'd come at me this hard."
It was a casual toss-out, but her face turned beet red, her eyes fluttering wide.
She seemed more embarrassed than when she'd stripped off her top, so I scratched my head awkwardly too.
"Or... are you really worried I'll do something with Geumbi noona?"
"Ugh...! H-honestly... imagining it isn't a crime, right?"
True. Thoughts and fantasies alone aren't crimes.
But the moment you act on them, you're judged one way or another... Hmm.
'Have I acted that suspiciously? I don't think I've flirted with my sisters or anything.'
I'd just welcomed their visits, comforted them when they were down, listened to their troubles.
...Wait, or did I? Those visits were late-night climbs into my bed, and the comforting happened alone in my room... Yeah, that could look suspicious.
'I thought it was normal for close siblings, but now I'm not sure. My head's a mess.'
Where's the line between okay and risky?
I couldn't get a read on what made my sisters wary of me.
...One thing was clear: this upright guy down here's responsible for a big part of it.
I'd hoped talking would calm my lower half, but with this view, it showed no signs of settling.
"Um, Jigu. Sorry if I'm overthinking. But... you keep pitching that tent, so it worries me."
"Ugh. I've said it a million times, it's just a guy thing I can't help... Haa."
Sujeong (Eldest Sister) must've been thinking the same, as her gaze dropped again, adding softly.
Maybe her eyes had been fixed down there the whole time, and with no excuse left, I dry-washed my face in lament.
'Yeah, my own fault. Got rock-hard staring at her naked body, then what credibility do I have ranting?'
For my earlier words to hold water, I should've been unfazed by her body now.
That flushed skin under the light, the soft smooth flesh, the prominent breasts squeezed by her arms, the deep cleavage pooling below her collarbone... I should've looked away for even 10 seconds.
I couldn't because, honestly, it was too tempting.
Admit it. Regardless of my heart, my eyes and body were definitely aroused by Sujeong (Eldest Sister).
"...I have no plans to cross the line with my sisters."
"Yeah, me too. ...But where exactly is that line?"
It was similar to something Geumbi (Second Sister) had asked once.
With my hunch that those two might not be blood sisters, I whispered the thought I'd had since then, a bit more bluntly.
"I won't do anything that could make a baby."
"Eek?! J-Jigu, you... that means...?"
"...Need me to say it harder?"
I thought I'd drawn the line tastefully, not too graphic.
Apparently not. It hit hard enough that she backed away from me for the first time.
Exactly half a step.
About the same distance I'd closed to whisper in her ear.
She stopped there, mouth flapping silently a few times, then squeezed her eyes shut and replied.
"M-me too... if it's that, I'm actually relieved."
"Really?"
"O-of course! Now that we've set it clear... I feel calmer. Phew."
Sure.
Her face and body were trembling like she'd collapse at a touch.
'What the hell did I just say? We're both crazy. It's the middle of the night—we're drunk on the mood.'
No other explanation.
So I'd chalk it up to that.
As long as we didn't cross the line, even if we weren't real family, it wouldn't matter.
And even if we weren't blood-related, after something like this, we couldn't go back to strangers.
'The problem is if we can't hold back and cross it, but that'll never happen. It's my sister, after all.'
One of us would stop—me or her—if it got that far.
Even if not, if no blood tie, other paths might open... Nah, scratch that possibility.
And the off-chance we crossed it and turned out to be blood siblings... I wasn't even thinking that.
"Eek?! J-Jigu, your hand?"
"Oh, sorry. Touching's off-limits?"
"No, ugh. There's... an order to things."
Does that mean she'll let me later?
You trash. How long ago did you resolve yourself, and you're already eyeing the next step?
Despite the self-scolding, my hand on her shoulder didn't pull far away.
She who'd stopped it swallowed hard, then lowered her own arms first.
Sujeong (Eldest Sister)'s bare chest—what I'd glimpsed for just 2-3 seconds before—was now jiggling into view not a meter away... no, less than 50cm.
"Today... just look with your eyes. It's embarrassing for me too."
She'd dragged me to the changing room, stripped herself with her own hands.
Yet she called it embarrassing now that it was visible, turning her flushed face aside while thrusting her real tits right at me.
"...Noona."
"Yeah."
"They're amazing."
"Eek?! Y-you... to your blood sister, what're you saying... Eek."
"But they really are pretty."
"D-don't praise those spots... Idiot, perv."
She chewed her lip more than ever, peeking at me then whipping her head away in a rush.
Even so, her pale, full breasts didn't retreat an inch, and I barely stopped my still-floating hand from going there by grabbing my wrist with the other.
'Haa, fuck. How am I supposed to hold back seeing this.'
All the complicated worries in my head vanished before those perky—no, voluptuous—breasts.
The hand that had halted with a hair's breadth of restraint slid down between my legs, gripping and stroking the pillar that'd been standing tall since earlier.
"Noona, Sujeong noona, ugh."
"Hng?! Ah, a-ahh...!"
In that moment, I couldn't hold back and rubbed my dick using her tits as a side dish.
Sujeong (Eldest Sister)'s eyes went straight to my crotch again, staring openly this time with no intent to hide.
The rough way a man grips and shakes his cock.
The massive tool between his legs that women lack.
Yet her eyes fixed on the breasts only women have, as she watched me pant and jerk off, holding her breath.
"Haa, ha, haa...!"
"Ah, ah, ugh......"
The changing room filled only with rough breaths and helpless moans.
No words, but at that moment, we siblings surely realized it.
There was no turning back now.
A train once started couldn't stop until it derailed.
...Or reached the end of the line.
Maybe that's why my rigid groin swelled even bigger.
