Chapter Title: Eldest Sister's Body
-----------------------------------------------------------------
It had only been five minutes... no, not even three since I started jerking off.
And yet, my cock was already heaving like it was about to explode.
'Why so fast... no, it's only natural. I've been holding back way before I even started touching it.'
I hadn't gripped and stroked it before, but the moment Sujeong unnie took off her top, I was already in trouble.
Now that my chatty mouth had finally quieted down, every sensation in my body was focused straight on my crotch.
Even so, the feel of my hand between my legs should have been the same as always.
Just like when I jerked off alone on my bed, same palm, same strokes.
'Why does it feel so different... fuck. Because this is right in front of me...!'
I cursed again, wanting to rip out this damn lighting right then and there.
The glow illuminating unnie's flushed skin had dyed even her breasts in a tantalizing orange hue.
They were already driving me insane with their size, shape, and that milky white skin.
With the lighting enhancing the view, I bit my tongue hard enough to nearly sever it, trying to stop my face from inching closer.
"Ji, Jigu... too close, ah."
"Sorry, but, I can't help it, haa."
On the edge, my lost lips nearly sank into her shoulder like a vampire's fangs.
Unnie shuddered at the nape of her neck but didn't pull away—instead, she tilted her head, exposing more of that pale skin.
And yet, here she was, protesting in that fragile voice that it wasn't allowed.
I couldn't hold back anymore. We'd made a promise, but just looking wasn't enough to cool this heat.
'As long as I don't touch her with my hands, it should be fine, right?'
Sujeong unnie had said to just look with my eyes.
If I interpreted it conveniently, that meant anything goes as long as my hands didn't touch her breasts.
"Unnie, come here for a sec."
"Hngh?! H-here... Jigu, wait...!"
I pulled the flustered Sujeong unnie into the bathroom.
Just in case, I shut the door the moment we entered, and she pressed herself against the wall, swallowing hard.
"N-no... don't do this, Jiguuu."
"Don't say weird stuff. I told you I wasn't gonna do that."
"Ahh, but... if you're just gonna look, why bring me here...?"
"The changing room light is dim. Easier to clean up here."
"Oh, is that it? Gotcha... phew."
Once I stopped touching her against the wall, Sujeong unnie seemed to understand and stroked her chest.
It wasn't intentional, but that made her trembling breasts jiggle up and down dramatically.
For a split second, my outstretched hand... barely, just barely, veered toward her shoulder instead.
"Hyah?!"
"As long as I don't touch your breasts, it's fine, right?"
"Ah, uh-huh... but why?"
"Can you sit down for a bit, unnie?"
"Huh? Why, like this...?"
"Yeah, just stay like that. Haa, haa...!"
She looked puzzled but obediently squatted down on the bathroom floor.
From above, I aimed at the cleavage of her breasts, panting as I bent my cock toward it.
"It might splatter, so close your eyes, unnie."
"Uh-huh...... hyah, hngh!"
"Hoo, h-haa... huaa."
Three seconds after Sujeong unnie closed her eyes, the semen burst from my cock at its limit.
The swollen glans gaped open wildly, as if the end of the world had come, spewing out thick white ropes.
The throbbing shaft trembled relentlessly in my hand, and I poured every last drop onto Sujeong unnie's ample breasts.
"Haa, ha, haa...!"
"Hyaa, hng, hnghh......"
Even with her eyes closed, she seemed to know exactly what was splattering on her skin.
Each time the semen hit her breasts, splashed, or trickled down, she hunched her shoulders and let out shaky breaths.
Worried it might overflow, she cupped the undersides of her breasts to steady them.
The cum splattered on her skin naturally followed the curves, pooling perfectly in the center of her cleavage.
"Ngh, haa..."
"Ahh... d-did you, finish, Jigu?"
"Yeah, I let it all out... unnie."
Five seconds? Ten? The endless climax finally ended—I wasn't sure how long it felt—and I reported to her.
Only then did Sujeong unnie flutter open her trembling eyelids, staring at my still-flushed face without looking away.
"...Why are you staring like that?"
"No, just... did it feel that good, Jigu?"
"......Don't ask weird questions. Of course it did, duh."
The belated wave of embarrassment and shame hit me.
Not the usual post-nut clarity, but the humiliation of showing unnie my full jerk-off session—it turned my face beet red.
Meanwhile, Sujeong unnie smiled faintly, as if finding my reaction cute.
But then her gaze dropped, landing on the pool of semen gathered between her breasts, and she bit her lip hard.
"Hyah...!"
"Ngh, sorry. I thought if I aimed anywhere else, it'd splatter on your clothes."
"Ahh, yeah. More laundry would just... make Geumbi unnie suffer."
It was a lame excuse.
We were in the bathroom—I could've shot on the floor or wall and rinsed it away easily.
Truth was, from the moment I dragged her in here, from the second I made her sit, I'd planned this.
I hid it behind my flushed face and lying lips.
Luckily, she bought my unconvincing excuse, and I was truly grateful—not just for her huge breasts, but for her generous heart.
"But, y'know... to wash this off... I guess I need a shower?"
"Ah, yeah. Body wash should get it out fine."
"Ahh, I know. I washed it off my stomach last time... remember?"
"Ah, right. Yeah...... uh-huh."
After cumming, I finally realized how insane this scene was.
Unnie's bare-chested tits covered in my load, and here we were, casually discussing how to clean it up like normal siblings.
I thought we were crazy, but Sujeong unnie dragged me into an even wilder dilemma.
"But there's only one bathroom... and you need to wash up too, Jigu. What do we do?"
"Uh?!"
She had a point.
The cum was pooled in her cleavage now, but I'd initially blasted her whole chest, so of course she needed a shower.
And I at least needed to rinse my crotch to feel clean.
'But if we're showering, she'd have to take off her pants too. Then we'd be in here together...... crazy! What am I even thinking?'
Upper body aside, the lower half was absolutely off-limits.
Any other time, maybe, but right now? No way—that conviction dominated every sense in my body.
"Y-you go first, unnie. I'll wait outside."
"Eh? No way! You'd be naked out there—what if you catch a cold?"
"I've been shirtless since earlier... and, y'know, standing naked in front of you is embarrassing?"
"Hngh?! Oh, no... s-sorry. I wasn't thinking—I'm sorry."
"No, no, you don't need to apologize... uh-huh."
Sujeong unnie finally clocked the situation and whipped her head away from my body.
But after she'd already seen my erection and my jerking off, there wasn't much left to be shy about—
'Shut up and play it cool. Getting out is the priority right now.'
I told the embarrassed unnie I'd clean up outside with some tissue.
She said to wait just a sec, promising to shower quick and come out.
With that, Sujeong unnie started showering inside, and I put out the fire with tissue before waiting by the door.
...But I hadn't accounted for how vividly her shower sounds would carry from behind me.
'Why is it so clear? The bathroom door isn't soundproof at all.'
Glass door, so yeah, but who cares—that was the last thing I needed right now.
Hearing it sparked dirty thoughts, so I squeezed my eyes shut, only for unnie's body from earlier to flash vividly in my mind.
Her pale skin, voluptuous breasts, slender limbs that looked like they'd snap if tapped.
I'd dumped my load on the meatiest part, and she'd lifted her tits to let it pool in her cleavage.
That lake of cum teetered on the edge—any tilt and it'd spill onto her collarbone and nape.
No such luck, so with deep regret, I imagined her letting it flow inside now.
'Showering it off with the head, sticky globs plopping to the floor? But still sticky, so she'd lather up a shower puff and scrub it all.'
Her breasts would jiggle with every motion, coated in slippery body wash instead of stickiness.
Her body would gleam like it was oiled up, tits bouncing way more wildly than before.
'Rinsing it under hot water... her body would shiver. Feels good, and it's steaming hot.'
Her heaving breasts settling with a soft moan—
My fingertips crept toward the door when I snapped my eyes open and slapped my cheek with my other hand.
"Ack...! Hoo, okay. That's better now, ha."
Fantasy ends here.
Lingering afterglow from the bathroom had made me lose it for a sec.
Regaining my senses, I wiped my crotch.
I gave the guy a stern warning not to perk up again like an idiot.
"Jigu, you still there?"
"Yeah, unnie. Right here."
"Then... can you hand me a top? And a towel too."
"Got it, here...... uh?!"
Unnie's voice came from inside, shower seemingly done, so I prepped to go in.
But the moment I turned, her wet upper body peeking through the door crack nearly gave me a heart attack.
"W-what, why aren't you dressed... I mean, showing everything...!"
"Towel and clothes are outside...? You already saw the top, so I thought it'd be fine... no?"
"No, ngh. ...Fine, dry off quick and come out. Make sure you dress properly."
"Uh-huh, thanks for worrying."
Sujeong unnie only poked out her upper body above the waist to grab the clothes and towel.
But that alone was a huge shock—and worse, the semi-transparent glass door half-revealed her lower half.
Her long legs, slim waist.
And right in the middle... that apricot-tinted spot I could only imagine burned clearly into my brain.
'No, no, no. Please, after all that, don't make me... ngh.'
My barely calmed crotch started heaving again.
This time, I shielded it firmly with the towel and clothes so unnie wouldn't notice.
After that, Sujeong unnie came out drying her hair, and I dashed in to wet my head.
......But in the end, alone inside, I ended up squeezing out one more round.
At least she'd gone out of the changing room, so no risk of getting caught.
"Ah, Jigu. Cleanup... go okay?"
"Uh-huh, sorry, took a while? Got lost in thought while washing."
"No biggie. Thoughts... can pile up, yeah."
"N-not those kinds of thoughts. Anyway, let's hit the sack... unnie."
Seeing her flushed cheeks, I tried acting normal.
But the moment we lay in bed facing each other, I had to turn away fast—nothing like usual.
"......Don't stare at Geumbi's side too much."
"N-no way that'd happen, don't worry."
"Really?"
"Y-yeah. Absolutely... I'd never lay a hand on you sisters."
As I rolled over, Sujeong unnie whispered right against my back.
I reaffirmed the promise to reassure her and closed my eyes.
Yeah, no way anything like that would happen.
Even today, I finished without touching her body at all.
'Shoulder doesn't count... as an exception, sigh.'
Maybe from the two loads, but sleep came quick and easy.
In my dreams, a familiar silhouette teased me all night, forcing me to curl up tight.
Childhood days felt so vibrantly different each one, but adulthood just looped the same routine endlessly.
Maybe that's why, just days after that thing with Sujeong unnie, Geumbi unnie called me over again.
"Jigu, what else happened with Sujeong unnie in the meantime?"
"Haaa..."
This familiar situation drew out a sigh on reflex.
I perched on Geumbi unnie's bed and tried talking first.
Three minutes into the chat, my pants and underwear were stripped clean off.
