Chapter Title: Bathing with Little Sister 1
-----------------------------------------------------------------
These days, I could feel my life starting to twist in ways I never expected.
Sure, it had always been a bit off-kilter from the start, but this was different.
Mom, my big sister, my little sister.
They were the new family who welcomed me in.
I cherished them more than anything—irreplaceable people I was deeply grateful for and fond of.
I love my family.
And I know they love me too.
But lately, that relationship was beginning to warp, bit by bit.
When did it start?
When my big sister started giving me those weird orders?
No, probably much earlier than that.
As I hit puberty, I started noticing the differences between boys and girls.
My big sister's budding breasts caught my eye.
I'd glance at Mom's underwear left out to dry.
Even the feel of Mi-so clinging to me made me flustered.
I was beginning to see my family not just as family, but as women.
Would it have been different if we were blood-related?
But we're just a family on paper—a fake one.
Maybe this was inevitable from the beginning.
Every day, I wavered between reason and desire.
But somehow, I made it through puberty without any incidents.
Not because my self-control was that strong, but because I was a coward.
I didn't want to lose my family. I didn't want to be abandoned.
One single mistake could cost me everything.
So I held back. Endured it, day after day—
And somehow, I turned twenty, then twenty-one, becoming a full adult.
—But my libido never settled down.
The way I looked at my family was still filled with desire.
Just like right now.
"Oppa, what are you waiting for? Come on in."
Mi-so, who had gone into the bathroom first, called out to me as I lingered in the changing area.
...Was Mi-so really that nonchalant about it?
Was I the weird one for feeling embarrassed around family?
No, this couldn't be normal.
I had to force myself to get out of here somehow.
"...Coming right in."
But I couldn't do it.
I couldn't resist the temptation.
First Mom, then my big sister, and now even my little sister Mi-so.
My desires were turning into reality, expanding their reach.
I opened the bathroom door and stepped inside, and Mi-so greeted me with a bright smile.
Of course, she was completely naked.
She'd already shampooed her hair and was rinsing off the suds.
She lifted her wet hair with both hands, arranging it neatly.
Every little movement felt like it belonged in a photoshoot.
Her skin was as white and pure as fresh snow.
It almost felt too precious to even look at.
I averted my eyes as best I could and turned on the shower next to her.
Water cascaded down over my head.
Mi-so stared up at me with wide eyes.
"...What?"
"Oppa, wash me."
"Wash what?"
Mi-so spread her arms wide in front of me.
She didn't show the slightest intention of covering herself.
"We used to wash each other. Remember?"
We used to bathe together all the time back then.
We were kids, so we'd splash around in the tub and play pranks.
Washing each other was just natural.
"...That was when we were little. You can do it yourself now, right?"
"Still! You promised and then didn't keep it!"
"No, that was unavoidable..."
I had no comeback for Mi-so's scolding.
I'd promised Mi-so I'd hug her every day and bathe together.
But I'd broken that promise more often than I'd kept it.
"Fine. If you hate it that much, forget it."
"No, it's not that I hate it..."
"Then what is it?"
Mi-so turned away in a huff.
A sharp pang hit my chest.
"...Okay. I'll wash you."
Whenever I went head-to-head with Mi-so, I always ended up surrendering.
"I love you, Oppa!"
Mi-so squealed with delight and threw her arms around me.
She rubbed her face against my chest.
But inwardly, I was chanting mantras to stay calm.
Because down there, I was already more than half hard.
As I reached for the shower puff to lather some body wash, Mi-so stopped me.
"No, Oppa. Use your hands."
"...My hands?"
"My skin's sensitive. What if I get hurt?"
"Still..."
"Here."
Mi-so snatched the body wash and squeezed a generous amount into my palm.
Then she turned her back and spread her arms again.
...Of course, things never stayed within the lines I'd imagined.
Why did God keep testing me like this?
No. It's fine.
This is just washing her. Nothing more.
So there's no problem at all.
"Ah♡ That tickles~."
When my soapy hands touched the nape of her neck, Mi-so flinched and shrank back in surprise.
"...Should I stop?"
"No! Keep going!"
Mi-so stood tall again like it was no big deal.
But every time my hands passed over her, her shoulders twitched.
I silently worked the lather over her body.
From her neck to her shoulders, down her arms to the tips of her fingers, with care.
Her skin was soft everywhere, yet springy and firm at the same time.
My big sister's athletic build was different, but Mi-so, as an idol, worked out plenty too.
I could clearly feel the toned muscles beneath her smooth skin.
It hit me anew just how hard she'd worked since middle school as a trainee.
"Haa... Feels so good♡"
As I massaged her fingers like a pro, Mi-so let out a moan of pleasure.
This was nothing for all the effort Mi-so put in.
I rubbed each finger thoroughly.
Once both hands were done, I moved back up.
She flinched again as I passed her smooth underarms.
"Ahaha. Tickles♡"
I tried to ignore it as best I could and soaped up her back and waist next.
"Mm♡"
A pleased little sound escaped her.
I shook off the impure thoughts creeping into my head.
"Haa...♡"
I skipped her butt and moved to her legs.
"Mi-so. Want to sit down?"
"...Yeah."
I sat her on the bath stool and started washing her feet.
She squirmed like it tickled, but I pretended not to notice.
I scrubbed between every toe, every crevice.
"Haa...♡"
In this position, if I looked up, I'd see Mi-so's most private spot.
I cleared my mind and kept my head down, focusing on her feet.
Soon, both legs were done.
All that was left was her chest, butt, and the front.
This had to be the end.
"Mi-so, that's it."
"Okay."
But Mi-so stood up and thrust her chest forward.
Asking me to wash it.
"......"
I wordlessly lathered more body wash into my palms.
And placed both hands on Mi-so's breasts.
"Mm...♡"
Smaller than Mom or my big sister, but still big for an idol.
The largest in her group, too.
Probably around a 65D... or so I'd heard.
She'd grow even more, no doubt.
Blessed genes, through and through.
"Haa, Oppa...♡"
Not just the size—the bounce was incredible.
They pushed back rebelliously against my fingers.
And at the tips, pretty pink nipples stood out.
The paradise countless fans dreamed of was right there.
"Mm-mmm♡"
Mi-so bit her lip to stifle her moans.
I finished up her chest like nothing happened.
Rinsed the suds with warm water, then moved my hands lower.
"Ah...♡"
I turned her around and washed her butt.
Two plump, peach-like mounds, full and firm.
I grabbed them with both hands and scrubbed without holding back.
"Ah♡"
After the outer parts, it was time for the cleft between.
Waste builds up there easily.
Even for an idol who seemed to live on dew alone.
I steeled myself and slid my soapy finger between.
"Eek♡"
As expected, Mi-so shrank back, embarrassed.
But I'd committed to this.
I felt every wrinkle of her puckered hole with my fingertip and cleaned it thoroughly.
Her body trembled with each pass of my hand.
"Oppa, Oppa......♡"
A little lower was her perineum.
A sensitive erogenous zone that's hard to reach.
I kept going, lathering it up too.
"Aaah......♡"
...By now, even I could tell.
Mi-so was feeling it from my touch.
She's not a kid anymore.
Physically or mentally, she's a grown woman.
No way she didn't know about sex between men and women.
No way she couldn't feel pleasure from this.
I pulled my hands away after her perineum.
"Mi-so. That's enough, right? You can do the rest yourself..."
We couldn't cross that line.
This was where my role ended.
But Mi-so wouldn't let go of my hand.
"Haa, haa, haa......♡"
She grabbed my right hand and guided it between her legs.
"Aaah♡"
The softest skin on a woman's body.
My fingertips touched Mi-so's slick, wet folds.
"Oppa, Sun-hu Oppa......♡"
Mi-so gripped my hand and started moving her hips.
This wasn't for washing anymore.
Mi-so was using my hand to masturbate.
"Ah, aaa......♡"
I felt something other than tap water on my hand.
Warm, sticky fluid.
Made by Mi-so's body.
Produced from her pleasure.
"Oppaaa♡"
Mi-so's eyes never left mine.
With her gaze, her expression, her movements, she poured out her pleasure.
I knew the thrill of being touched by someone else's hand.
Mi-so must be feeling that right now.
I met her pitiful gaze and stroked her wet hair.
"Haht, haht, haht♡"
Mi-so's breathing grew ragged.
Just swaying her hips while standing still, it was like she'd run a 100-meter dash.
Her face flushed bright red—I worried she'd collapse.
"Oppaaa......"
Mi-so gave me a pleading look.
What she wanted in this moment? No need to guess.
"Aaah......♡!!"
I didn't know much about pleasuring a woman.
Just the spot Mi-so had desperately rubbed against my hand.
I rubbed it directly with my fingers.
And the effect was immediate.
"Haht, aaaah......♡!!"
Mi-so's head snapped back.
She rose on tiptoes, arching her back.
I quickly pulled her into my arms before she fell.
"Aa, aaaa......♡"
Her delicate body shivered in my embrace.
I held her tight until the tremors subsided.
Her hot skin felt like it was burning mine.
"Oppaaa......♡"
Glassy eyes.
A voice on the verge of fading.
In the end, I'd twisted my relationship with Mi-so too.
"Oppa... I'm okay now."
"...Yeah."
A moment later, at Mi-so's words, I loosened my arms.
Her face was still flushed, her breath a little uneven.
But her expression looked happier than before.
"My turn now♡"
Mi-so glanced sideways at my raging erection, grinning like a kid with a new toy.
I had no way to hide it at full mast.
