Chapter Title: Siblings' Secret
-----------------------------------------------------------------
Sujeong's hand touched my waist.
She lifted her shirt just enough to show a sliver of her navel, slipped her hand inside, and hesitated for a moment.
'Is she wondering which side to take off...?'
Her arm trembled in this place where she could go either up or down.
I could've sworn I heard her mutter something like "let's stop this right now," but no sound reached my ears.
"This side... it's at least a little better."
What did that mean?
Was it less embarrassing for her, or did she feel more confident about that part of her body?
It seemed like the former, but given the skin she was revealing, the latter was possible too.
Sujeong was slowly pulling up her sleeveless tee instead of her pants.
'Crazy, crazy, this is insane... gulp.'
This wasn't the time for it, but I swallowed hard without thinking.
The shirt passed her navel and solar plexus, exposing the underside of her breasts like she was wearing just a bra.
Finally, as her top rose even higher, baring about half her chest...
"Ow, turn around, turn around... Jigu."
"Huh?! Oh, like this? Sujeong?"
"Yeah... sorry. I'm a bit embarrassed, just until I'm done undressing..."
"Ah, okay, yeah. Take your time... phew."
At Sujeong's cry, I quickly turned to face the wall.
My face, ears, and nape were burning red, so this gave me a moment to breathe too.
'Now I'm fully her accomplice.'
I could no longer claim she'd forced me into this.
I'd admitted to knowing exactly what she was doing and not stopping her.
'...But doesn't this mean my ass is totally exposed? I'm barely covering the front with this towel.'
As I scolded myself and crumpled the towel in my hand, I realized my rear was defenseless.
And Sujeong, blushing furiously with her eyes cast downward, clearly had a full view of it.
"...Gulp."
"Hm?"
Was it my imagination?
I heard someone swallow secretly behind me.
No way to check, so I stayed quiet, but pressing my legs together was my minimal defense.
"I-It's... done now, Jigu."
"Ah, okay... Can I turn around now?"
"No! I mean, ahh... no, really, you can't..."
What on earth did Sujeong want to do?
She ignored my excuses and protests, but now that she'd taken off her top, she wouldn't let me look at her.
She just clung to my back, breathing in and out repeatedly.
Her breath occasionally brushed my back and shoulders. I steadied my pounding heart and made sure not to glance at the mirror beside us.
'It's not like I really want to see her body. I never even imagined things turning out like this with Sujeong.'
Thanks to her intense shyness, I could cool my head a bit.
With some breathing room, I pondered why we'd ended up like this and what was going through Sujeong's mind.
'On the surface... it was worry about Geumbi. The timing and circumstances did look suspicious.'
I had to admit that part.
I'd reacted when Geumbi's hand brushed me in bed, and she'd caught me watching that video in the changing room.
'But... just for that? We're family? Siblings who've lived under the same roof for decades?'
Still, I felt her actions had crossed a line.
In the end, the only thing that made sense was that recent issue plaguing us.
'Sujeong must think... she's the adopted one.'
If so, everything clicked.
If they weren't blood-related but legally could even marry, all sorts of thoughts would arise, making this understandable.
'Even if it were me who's adopted, the problem's the same. Either way, she'd think it's better if the suspicion points to her than Geumbi.'
That was her personality.
Insisting on playing the eldest sister role even now—it was so typically Sujeong, and impressive.
'But... does that mean she wants to marry me or something?'
Even so, one final question lingered.
Normally, she'd scold me sharply or chew me out.
Why volunteer as a sacrifice and press her body against mine?
Every step was so her, but the outcome felt unlike her—one secret that didn't fit.
That keyword rattled my mind, and just as I resolved to ask her directly—
"Eek?! S-Su-Sujeong?"
"Sorry. I just... can't face you. Sorry."
"No, that's not it—why would you...?"
Sujeong hugged me from behind.
A classic back hug. Her arms wrapped softly around me, her body pressing seamlessly against my back.
Yes, her soft upper body.
The touch of her bare, snow-white skin filled my back right now.
"Will this do, Jigu?"
She pressed her cheek to my back too, her voice flowing over my skin.
I couldn't misunderstand her words, but I had to ask the question I'd been mulling.
Why was she doing this?
Did she really like me that way?
"Sujeong."
"Y-Yeah."
"...Come a little closer."
"Eek?! Ah, like this? This close?"
"Yeah, perfect. Just... keep hugging me like that."
"O-Okay... eek."
Sujeong pulled her arms tighter, pressing fully against me.
There was no space left between us. Naturally, the flesh of her breasts, her skin, her body heat stimulated my back.
'How am I supposed to ask now...? If I do, I might never face her again.'
We'd lived as family our whole lives.
Asking out of nowhere if I saw her romantically? What if yes, what if no?
'Either way, our relationship ends... Huh?'
As I bit my lip and sighed, another possibility I'd overlooked hit me.
What if Sujeong was wrestling with the same doubts? The situations looked suspicious from her side too, so maybe she was doing this to preserve our family ties.
'If that's it... it's such a foolish thing to do.'
No matter how little she knew about men, or how odd my behavior was.
Doing this while wanting to stay family to the end—I should get mad or make her rethink it.
But down there, it was impossible anymore.
From the moment she'd entered the changing room, spoken to me—it had been my limit.
"Sujeong, sorry."
"Huh? Wh-what? Ahh...!"
I slipped my hand under the towel and carefully gripped my swollen erection.
I'd tried cooling my head as the heat built below, but Sujeong's fleshy assault finally breached my defenses.
Like a man left alone on an open plain.
My hand ignored everything around it, rubbing the thick shaft under the towel.
"Ahh... J-Jigu. Are you... doing it right now?"
"...Don't talk. Can't focus."
"Ah, sorry... I'll be quiet."
I hadn't meant to snap, but it must've been tougher than expected.
Once my hand started, it wouldn't stop, and with reason gone, my gaze slowly turned sideways.
To the mirror on the wall.
And there... a busty woman was hugging a naked man without hesitation, her top off.
"Hah, hah, hah...!"
"Eek, hm..."
Shouldn't have looked.
I could've stayed calm with just the feel, but seeing it drove me mad.
'At least I only see the side boob. ...But damn, it's huge. More breast than the arms wrapping around.'
Her breasts pressed against my back covered more area than her hugging arms.
I felt my cock swell from shaft to tip, imagining things I shouldn't with my sister.
'Soon, like this... ugh.'
If I came here, it'd all be over and done.
Maybe a rebound from overthinking earlier—my reason fled, heart consumed by instinct, demanding more.
"Sujeong."
"Hm? Wh-what...?"
"Can you turn around just once? Face me?"
"Huh? You mean... face-to-face?"
"I won't look at your chest. I'll hug you right away."
"Eek, hahh... Okay. Just for a second—kyaa?!"
The moment she agreed, I spun and pulled her into a tight embrace.
The towel covering my front fell mid-turn, and her bare breasts pressed directly against my chest, no barrier.
"Hoo, hah, hah...!"
"Ahh, Jigu, haaaah..."
Did she hear my heart—thudding, no, pounding?
Not sure. With breasts this full, who knows if the pulse reached inside.
"Ugh, Sujeong, now... ugh!"
"Eek?! Ah, ahh... hiyaaa..."
One arm around her, holding her so not even 1mm could escape.
I unleashed the dizzying desire below her navel, onto her belly.
"Hoo, ha, haa..."
"Ahh, this is... that, that stuff... uwaa."
Sujeong knew little of men, and this seemed her first time seeing semen.
...Her first load being her little brother's, splattering her body. Returning reason stirred complex emotions.
"...Sorry for dirtying your pants."
"N-No, it's because I didn't take them off..."
"Huh?"
"Eh? ...N-No! I wasn't gonna take these off too. So, ugh... I-I'm gonna wash up! Can I shower first?"
"Ah, sure. Of course, Sujeong."
"Th-Thanks. Um, and... can you grab some new pants from upstairs? Please..."
"No, it's fine, I should... yeah, I'll get them."
Looks like reason returned late for her too.
Where'd that bold body go? Sujeong flailed awkwardly like a nerd and fled into the shower.
I waited for the changing room door to close, wiped up roughly with tissue, dressed.
Instead of the semen-soaked pants I'd dirtied, I grabbed dolphin pants from Sujeong's room.
'Ah, should've just brought long gym pants.'
Heading down the stairs, I wondered why I'd picked these.
But in my memory, she wore them nine times out of ten, so I scratched my head and waited by the changing room door.
"Ah, Jigu...?"
"Yeah, I'm here. Pants?"
"Yeah, hold on... opening the door now."
"Huh? You can just reach out."
"No, you need to shower too. I've got clothes on now... come in, it's fine."
"Ah, okay then... Huh?"
I turned at her call, but the sight wasn't fine at all.
Her damp hair clung slightly to her shoulders, water droplets trailed from cheeks and nape to her collarbone.
But worst was what she called "clothes."
Just the sleeveless tee I hadn't dirtied—pulled down precariously to her hips, nothing below.
"Wh-Why...? Is it not enough anymore? Like that."
Sujeong blushed deeply, averting her eyes as if asking if once wasn't sufficient.
That pose, those movements, her expression—how any man would see it... I barely suppressed the urge to tell her.
"Go to your room first. I'll shower slow and come back."
"Ah, okay. Um... good job, Jigu."
"You too. Thanks a lot... really."
What exactly was I thanking her for?
I handed her the clothes, entered the changing room, stripped quickly, and headed to the shower.
Sujeong went to the living room, put on pants, and headed to my room.
I cranked the shower hard, drenching my head like under a waterfall.
'I must've been possessed. Held back for days, lost my mind...'
I'd thought fantasizing about my sister was crazy enough.
But tonight, I'd pressed chests with her at midnight and ejaculated on her belly and pants.
Maybe I was still in bed, this a wet dream? I closed my eyes tight.
But all that returned... was the vivid, squishy softness of Sujeong's breasts lingering on my skin.
