Chapter Title: Making a Promise with My Little Sister
-----------------------------------------------------------------
When I was little, I had a phobia of bathrooms.
It was because my biological parents mostly abused me in the bathroom.
They hit and kicked me a lot, for the most part.
Sometimes they'd dunk my head into a full bathtub.
Or pour ice-cold water on me in the dead of winter.
Or the opposite—scald me with hot water.
Depending on the situation, they'd add punishments like that.
Because of it, I ended up terrified of bathrooms.
All my memories of them were nothing but pain and fear.
Even after I was adopted into this family, it was the same.
The first time I stepped into one here, I screamed and bolted right out.
My big sister grabbed me and dragged me back in.
Mom washed my body with her gentle hands.
Mi-so played around next to me, showing me that the bathroom wasn't a place of pain—it was fun.
Right. It wasn't the bathroom that hurt me. It was my biological parents.
Now I was with a new family, not those parents.
There was no reason to fear the bathroom itself.
It took me a long time to realize that simple fact.
Even after that, bathing together as a family helped my phobia fade bit by bit.
Those times were a blast.
We'd fill the big tub and splash around.
Sometimes I'd slip and fall on the wet floor, but compared to getting beaten by my biological parents, it didn't even hurt.
Then my big sister's chest started growing, and we naturally began bathing separately.
Was that already ten years ago?
Bathing together with Mi-so like this had been just as long.
"Hua...♡"
Mi-so sank into the tub.
She let out a pleased sound, the warm water feeling good.
Yeah. Up to that point, it was fine.
The problem was that I'd gotten into the tub first.
And Mi-so had plopped right down on my lap again.
This tub was huge.
Big enough for five or six people at once.
So there was no need for Mi-so to sit on my lap.
Mi-so's butt settled onto my thighs.
Her body was soft yet springy.
Something similar had happened with So-young Sister, but now that we were both naked, the sensation felt even more vivid.
"Um, Jin Mi-so?"
"What?"
Mi-so's reply was still icy cold.
Even in the steaming hot water, it chilled me.
"...The tub's plenty big. Do we really need to overlap like this?"
"Why? Am I too heavy?"
Every word out of her mouth was sharp as a blade.
"No, you're not heavy at all. It's just kinda..."
Right now, I was desperately holding down my dick as it tried to stand at attention.
If it went full mast, we'd have a real problem.
...But I couldn't exactly tell Mi-so that.
This was something I had to endure alone.
"Then it's fine."
Mi-so relaxed her body and leaned back against my chest.
Her wet skin stuck to mine.
Why was every part of a girl's body so damn soft?
"...Or do you hate me that much?"
Her voice sounded a little sulky, almost sad.
"No way. Why would I hate Mi-so?"
"Then why aren't you talking to me?"
"Well, it's..."
I was at a loss for words.
I couldn't say it was because big sister told me to.
I'd planned to come up with excuses, but nothing had come to mind yet.
"What is it? Why won't you talk to me? You ignore my texts. You don't talk. You don't even smile. If I did something wrong, just tell me. So why won't you say anything?"
Mi-so's voice started to waver as she spoke, like she was on the verge of tears.
I had no idea what to do.
"Sorry. It's not because you did anything wrong, Mi-so. It's my fault."
I tried my best to soothe her.
It'd be great if I could come up with something clever to say right now.
"Why you?"
"Well, I'm adopted, right?"
"...So? Why bring that up now?"
"If we were real siblings, no one would care if we got along great or fought all the time. But since we're not blood-related, if we're too close, some people might think it's weird."
Mi-so whipped her head around to face me.
Her eyes were brimming with tears.
"What the hell? Who cares what other people think!"
She had a point.
A normal person wouldn't give a damn what anyone said.
But Mi-so wasn't normal.
"You're an idol. Even if you do nothing wrong, some people will try to tear you down anyway."
"Where's that fair? If that's how it is, I'll quit. I'll announce it tomorrow."
Quit? Quit being an idol?
Her sudden declaration shocked me.
Whether she told her agency or posted on SNS, once the words were out, there was no taking them back.
Even if she backpedaled later, the damage would be done.
"Wait, calm down, Mi-so. You can't just quit on a whim like that. What about the other members? It's not fair to them."
"I don't care. I don't need any of it. What's the point?"
She seemed dead serious about quitting.
Was it because of me? Had I said something stupid?
I should've been more careful with my words.
"Sorry, Mi-so. My bad. So don't say you're quitting, okay?"
I threw in the towel.
Her getting upset enough to quit over me? That was something I couldn't let happen, even if I died.
"...For real? You won't ignore me anymore?"
"Yeah. For real. I promise."
No helping it.
I'd have to come clean to big sister and beg forgiveness.
"Then grant three wishes for me."
"...Let me hear them first."
Mi-so was suddenly full of energy.
What was with those tears just now...?
"First. No more ignoring me."
"Got it."
That was a given, so I nodded easily.
"Second. Bathe together like this every day."
And the second one was straight-up absurd.
"That's... Mom and big sis would kill us if they saw."
"Then just when Mom and Unnie aren't home!"
"Still, no..."
Siblings over twenty bathing together? That was weird no matter how you sliced it.
But with her hands clasped tight and those pleading eyes looking up at me, I caved.
"...Fine. Just when Mom and big sis aren't home."
"Yay! Just when they're gone!"
Mi-so beamed like she was truly thrilled.
Was this really okay...?
"Third. Hug me tight three times a day."
"...That's a bit much too."
"Just when Mom and Unnie aren't home!"
Less extreme than the second, but still problematic.
My only excuse for refusing was that Mom or big sis couldn't find out.
But they were busy with work and out of the house a lot.
With Mi-so's condition of "only when they're gone," I had no ground to stand on.
"Okay, then everything only when it's just us two. But when Mom or big sis is home, we act like we're not that close."
Mi-so eyed me suspiciously at that.
"Hmm. Oppa, did you hear something? From Mom or Unnie?"
"No, not exactly..."
She hit the nail on the head, and I panicked.
I tried to play it off, but who knows if it worked on her.
"Whatever. Fine. So we pretend not to get along normally?"
"Yeah."
"I'll keep my promise, so you keep yours too."
"Got it."
"Then, today's hug."
Mi-so spread her arms wide and hugged me from the front.
Hard. Like a koala clinging to a tree.
Her chest pressed against mine.
Her thighs wrapped around my waist.
Being naked, our nipples touched naturally too.
The feel of Mi-so's body transmitted through every inch of me.
Honestly, I couldn't stop my dick from getting hard anymore.
"Hey, Mi-so. Can't we do this with clothes on?"
"Nope."
"Sigh..."
I managed to get the words out, but she shot me down flat.
"You gotta hug me tight too, Oppa."
Mi-so whispered, sounding dissatisfied.
Right now, she was just hanging onto me.
But was it okay for me to hug back like this?
"If you don't, we're not done."
With that, I had no choice but to wrap my arms tight around her back.
Mi-so's body in my arms was slender enough to snap, yet impossibly soft.
She felt even hotter than the bathwater.
"Mm-hmm♡"
Mi-so let out a pleased hum.
Then she started rubbing her body against mine, little by little.
"Hoo...♡"
Oh no. This was dangerous.
My whole body marinated in pleasure.
Her breasts, her belly, her arms, her thighs—they rubbed against me, sparking ecstasy.
Was the human body always this sensitive?
My dick was already rock-hard, poking the back of her butt.
All I could do was pray she wouldn't notice.
"That's one. One minute each time, so...♡"
Three minutes like this?
That was barely enough to cook instant ramen.
So why did it feel so endless?
I gave up on thinking.
"Now twooo. Haa... Mm...♡"
Still a whole minute left?
I felt like I'd boil and fall apart before the ramen did.
"...Threeee. Done!"
At three, Mi-so finally let go.
I sighed in relief and loosened my arms.
"Okay, Oppa. I'm heading out first, so see you tomorrow. Take care."
"...Only when Mom's not home."
"Yeah. Just us two♡"
Mi-so hopped out of the tub, splashing water everywhere.
Didn't she feel any shame around me?
She didn't even try to cover up as she headed out of the bathroom.
In the now-lukewarm tub, my swollen, lost dick floated aimlessly.
