Slave Water Tank (Chapter 3)
【Beer Tavern Tank (hereafter, “Beer Girl”)】
〇The slave tank herself listens to customer orders and serves beer that has been matured inside her body.
( Ultra-short distance transfer magic allows beer to be poured directly from her body into a mug.)
〇Serving customers is also part of the Beer Girl’s job, and she is expected to act cheerfully and with a friendly attitude.
〇The beer inside her body causes carbon dioxide gas to build up due to her body temperature, so the pressure in her belly increases over time.
(To avoid reaching her limit, she must keep selling beer frequently.)
【The Beer】
〇A special kind of beer matured inside a woman’s body.
〇Younger women are more popular.
〇The taste and aroma vary greatly depending on each slave tank’s physical constitution.
【Bursting Room】
〇A small room where a beer tank can meet her end when her belly reaches its limit.
(It is a facility prepared to make cleaning up afterward easier.)
〇The location and usage differ depending on each tavern.

【Chapter 1:Bursting Blossom Tavern】
“…Is this… a tavern?”

Looking up, I saw a large signboard that read “Bursting Blossom Tavern.”
It was an old two-story wooden building, with blackened beams and a heavy door bearing the marks of repeated repairs.
Warm light spilled out from the small windows.
“Gahaha! This one’s a winner—it tastes great!”
“Hey, give me a ticket too!”
Lively voices and cheerful laughter drifted out from inside.
But mixed in with the smell of alcohol, there was also a sharp, unpleasant odor that stung my nose.
This smell…
It was raw and foul, like waste and vomit, with a metallic tinge mixed in…
“Eek!?”
A wave of intense anxiety ran through my whole body, making me tremble.
This smell… It’s the same as when Selina’s belly burst…!
“Don’t stop. Keep walking.”
The slave merchant pulled me forward by the hand.
The heavy back door creaked open with a groan.
At once, the smell of alcohol—and that terrible stench—rushed over me.
My chest tightened; my heart pounded faster and faster.
In the dim light beyond, I saw a single figure move—a girl in serving clothes.
She was holding her unnaturally swollen belly as she walked slowly.
“I have to… sell it quickly… or else… my belly…”

Is that… could it be…?
A Beer Tavern Tank!?
That smell—there’s no mistake.
I remembered what a friend once told me about this “dangerous job.”
“Beer Tavern Tank”
A job where you use your belly as a barrel and store lots of beer inside.
When customers order, you have to pour beer from your own belly and serve them.
You’re supposed to smile and act friendly while serving, too.
But as the carbon dioxide in the beer turns into gas from your body heat, the pressure in your belly keeps rising higher and higher.
So you have to sell all of it before reaching your limit.
In other words, if nobody buys from you…
“What are you doing here at this hour?”
Startled, I looked up to see a sturdy old woman with white hair standing at the back.
She wore a black robe and a faded apron, her thick fingers glittering with several large rings.
“Well now, is this a new Beer Tavern Tank? She’s quite cute!”
Her low, booming voice echoed through the room.
“And…”
Her sharp eyes glinted as she stared at my body up and down.
“I see—this is some fine stock. How much?”
“Ah, well… um… This girl is quite—”
“Calling me out at this hour—aren’t you getting bold?”
“Oh—no, no! It’s not that…”
After a while—
Once my payment was settled, the slave trader quickly made his escape.
I was left alone with the old woman.
“From today on, you belong to me now, my girl.”
【Chapter 2: The Bursting Room】
“Listen, from today you’re a ‘beer girl.’ You’ll call me Master, got it.”
Beer girl?
Here, that’s what they call the Beer Tavern Tanks.
“It’s already late tonight. I’m putting you in charge of the bursting room. Learn your job there.”
…The bursting room?
I didn’t know what kind of place it was, but I already had a bad feeling about it.
Master led me through to the back of the tavern.
With every step, that awful smell grew stronger and stronger, until my head began to spin.
“This is the place.”
A tiny shack.
Dark red stains still wet on the walls.
The marks trailed down to the ground, where bits of flesh and clumps of human hair lay scattered about.
What… is this place…?
Just one look told me it wasn’t somewhere normal.
There was a rotten stink mixed in as well, making me feel even sicker.
“I’m leaving the rest to you.”
With those words, Master left right away.
Wait, “leaving it to me”… What am I supposed to do?
Just then…
“H-hahh… hahh… I-I made it… ugh…”

A girl with a hugely swollen belly burst into the room.
Just from looking at her, I could tell she was probably a beer girl.
Panting heavily, she hurriedly began to untie the strings of her apron.

“A-ah… m-my belly… it’s so… big…”
Her stomach was swollen to the limit.
It was probably packed full of beer and carbonated gas.
She stripped off her underwear and shoes too, leaving herself completely naked.
“Take my uniform—hurry, please!”
She shoved her clothes at me, barely giving me time to react.
Wait—what am I supposed to do with this?
“What are you spacing out for!? Hurry up and put it away!!”
The beer girl screamed at me, tears in her voice.
I scrambled to open the door of the shack.
Inside were six round stools with no backs, all lined up neatly.
I guided her to one of them.
“A-ah… thank goodness… ngh…”

She sat on the stool, clutching her swollen belly in pain and curling over.
Not knowing what else to do, I just stood by and watched her.
“Ugh… ah… Are you… a new girl?”
I gave a small nod.
Her eyes widened for a moment, then she gave me a faint, powerless smile.
“Heh… well then… I guess… this is my… ngh… my last job…”
She started to explain this place to me.
“Bursting Room”
It’s a place meant solely for beer girls to burst.
Because blood and flesh fly everywhere when they burst, it’s meant to make the cleanup easier.
When a beer girl nears her limit, she has to come here on her own and face the end.
If you burst here, your body gets buried in the communal graveyard.
But if not, your remains are put on display as animal feed or fertilizer for the fields—meant as a warning to others.
“A-and after this… ngh!? Uuuugh!!!”
Her voice broke off into deep groans that echoed through the little shack.
Her belly writhed irregularly; inside, the beer sloshed and gurgled loudly.
Blood-flecked foam spilled from her lips as she scratched desperately at her stomach with her nails.
“Don’t look at me!! Get out!!”
Her scream was so raw it didn’t sound like it came from a woman at all.
Startled, I hurried out of the shack.
SCRATCH! SCRATCH! SCRATCH!
“I-it hurts! It hurts! It hurts!!”
Through the door I could hear both her screams and her nails raking across the wall.
She’d used up what little time she had left just to explain things for my sake. She must have been truly kind—someone who looked out for others even until the end.
Thinking that made my chest tighten painfully.
“Aaaghhh!!!”
Splat!!
A dull bursting sound.
Splatters of flesh and bodily fluids hit the walls and floor with sickening splashes.
And then…
That unique smell that always fills the air whenever someone’s belly tears open right before your eyes.
“Guh—gweh—!”
Unable to hold it back any longer, I vomited up everything rising from my stomach.
My whole body shook—I couldn’t move at all.
But… I had work left to do.
I had to give that girl proper rest—that was now my duty.
On shaky legs, I stood up and carefully opened the door of the bursting room…

“Wheeze… wheeze…”
In the silent little shed, only the faint sound of breathing echoed.
She’s still alive…
The girl slumped weakly against the wall.
On the floor, her spilled intestines and organs lay strewn, having burst from her belly.
Thick, dark red fluid oozed from her exposed flesh.
“Gahh… uuuh…”
A painful groan escaped her lips as her body trembled.
For a moment, her eyes glared at me—then she stared fixedly at a wooden box in the corner of the shed.
Could it be…
Is my job to put her inside that box?
The box was bigger than I’d thought—big enough for one of us to fit inside easily.
“…hhh… hhh…”
Her vacant eyes wandered toward the ceiling. Bloody foam dribbled from her mouth.
She was still breathing—but it could hardly be called living anymore.
I dragged the wooden box in front of her and quietly waited until all movement stopped.
“………………”
I gave her back a gentle push and she toppled into the box with a dull thud.
Her limbs stuck out awkwardly, so I tucked them inside and closed the lid.
After that, I dragged the box out of the shed.
I guess… I have to clean up too.
Using plenty of water from the well, I washed out everything in the little shack,
watching out of the corner of my eye as what remained of that girl was swept away by the water.
