What the Fuck is 100 Billion?

"Fuck, what the hell is 100 billion?"

Tweet tweet—

"Ha."

I woke up to the sound of morning birds, rubbing my bleary eyes as I propped myself up. Huh, when did I even fall asleep? The thought flashed through my mind. Come to think of it, yesterday—

"My money, fuck!!"

The bizarre system message suddenly came back to me. But that wasn't the important part. Did I just say that?

"What is this voice?"

A high, delicate voice reverberated through the room. Haha, must be hearing things since I just woke up.

"A-ah—"

I tried making a sound again. It was a clear, beautiful soprano like a coloratura.

"……."

Right then, that disgusting blue window from yesterday popped up in front of my eyes again.

"What? Irina? What the fuck are you—"

Irina? What bullshit is this? I reached out to grab the blue window, but it was like it was etched onto my retina—I couldn't touch it.

What...? My name is Irina... no, Irina....

......?

My mind went blank. My name was definitely... definitely... what was it? Whose name was on my coin account?

"You bastard... wait, did I even say that?"

My awkward voice echoed in my ears. I was sure I hadn't said anything.

My head throbbed. What the hell is this thing? Why am I in this state?

Ding—!

"...Give an honest review?"

"You crazy fuck."

I stumbled toward the mirror. One step. Two steps.

"...Huh?"

My balance felt off. My body leaned forward, then corrected itself late. My chest—followed a beat behind.

A curse nearly slipped out, but my voice trembled thinly instead.

The biggest problem was my current state. The shirt I was wearing was way too big. It kept slipping off my shoulders, and my chest... damn it, buttons were already popping off.

"Holy shit, even walking is hard."

I wobbled to the full-length mirror.

"...!!!"

A stranger—a cute girl—stood in the mirror. Sky-blue hair cascaded over her shoulders, huge eyes quivering like they might spill tears any second.

But my gaze didn't stop at her face.

This is insane, insane, insane...!! What the fuck is this size?! How am I supposed to walk around with these?! Won't they give me scoliosis?!

"What? Where's that even—"

This asshole had no intention of listening. I swallowed hard.

With this body, staring at these bursting tits in the mirror, and giving an honest review?

"Ha, sh—!"

The curse rose to my throat but wouldn't come out. No way I had women's clothes. And like it planned this, the ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠quest reward was...

Right now, all I had was this one shirt. Even that had lost its buttons, exposing my chest.

"...S-so..."

My voice crawled out like a mosquito.

"A-a pretty girl with sky-blue hair and blue eyes... is in the mirror."

No, I did it!! What's missing?! I was honest!!

No matter how much I screamed inside, the system window didn't budge. If anything, the :P emoticon looked like it was mocking me.

"...No way."

I stared at the massive flesh jiggling between the gaps in the shirt. My slender fingers gripped the hem, trembling.

Is it seriously telling me to say that?

"A-alright! I get it!! Just say it, right?!"

I squeezed my eyes shut and screamed at my reflection.

"Th-the tits are so huge the shirt buttons all popped off... a pervert's huge-titted... cute girl is what I see!! Happy now?!"

Ding—!

"Haa, haa. You piece of shit..."

"N-no, nothing..."

I doubted it'd work on something that read my mind, but I shut up to avoid saying something stupider.

Poof! A wardrobe appeared in front of me. What the hell, is this a hidden camera? A dream? I pinched my cheek. Ow. Not a dream, then.

It didn't say to open it, so do I have to? Still, better check what's inside.

I approached the wardrobe slowly and creaked the door open carefully.

Bang—.

"F-fuck. Fuck..."

For a split second, I glimpsed clothes too obscene to describe. I slammed the door shut.

It's telling me to wear that?

"Taste my ass!! Is that what you call clothes?!"

"Cut the bullshit!! What the hell do you want from me?! Why am I a girl?!"

Silence fell over the room at my shout. The :P vanished, replaced by a more serious-looking [ ? ] in black text.

"Why 100 billion in the first place—!!!"

Ding—!!

"...You mad bastard. All the way..."

With shaking hands, I opened the wardrobe door again. I'd skimmed before, but up close it was worse. The most normal-looking was a white oversized shirt (no bottoms).

How is there not one normal outfit? I couldn't go outside like this. Not that I wanted to with this body.

Far right...?

"......"

I was beyond cursing. What even is this? Is this called clothes? Does it intend to cover anything?

The system's pick was a slingshot bikini. ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠Barely enough fabric to cover nipples.

Why wear it at all? Reward sucks anyway.

Sigh, fuck. "No way in hell."

I snatched the white oversized shirt from the far left. I'd die before wearing a slingshot bikini. That's crossing the line.

"...Haa, gotta take this off first."

Buttons all burst on this shirt. I looked up at the ceiling, closed my eyes, and stripped.

Cool air brushed my collarbone, back, chest. Chills ran down my spine.

"Hngh..."

With a tiny moan, I slipped on the new shirt. Trembling arms into sleeves.

But...

"...Ugh, hah?"

The fabric grazed my chest, sending an unfamiliar sensation ripping through me.

What, what is this?

It stung yet tickled—an indescribable, weird swirl inside. Plus a gross heat pooling in my lower abdomen, something I'd never felt and shouldn't.

Shaking hands fumbled buttons from the bottom up.

But...

"Eugh..."

Tits too big—couldn't button past the middle.

"Argh...!!"

Ignoring the taunting system, I barely buttoned it all.

"Haa, ugh... uugh..."

Hand on the wall, barely holding myself up. Shirt too tight—hard to breathe. Just one shirt, and my whole body burned like fire.

I looked up. In the mirror: a girl in a shirt swollen taut like it might burst.

Is this really me? As the system said, pink shone faintly through the white fabric. No bra, duh. So every movement made them jiggle, messing my vision.

Damn, me in such embarrassing clothes...

...? Still, better than the other crap inside. Least exposed. The rest weren't even options. God knows what it'd do if I went naked.

"...Hoo, yeah. This is the best."

I pressed down my bursting chest and sighed deeply. Just a shirt, but covered for now. Crisis averted.

But.

"...What?"

Ding-dong—!

The doorbell rang through the officetel like magic.

"Oppa! You up? I have the key, coming in!"

My one and ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠only little sister, Yuna's voice from outside.

Normally I'd yell, "Hey, you crazy? Get out!" But now my voice was a soprano girl's. And my state... no-bra, no-pants, shirt buttons one breath from popping under tit weight.

Ding—!!

"Y-you crazy... you see how I look right now?!"

I glared down at my chest, clearly visible through the shirt, cursing.

Please, please don't come in...!!!
