Slave Water Tank (Chapter4)
【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 3: Working in the Hall】
“Eek… ugh…”

A cold metal tube pushes deep into my stomach.
Glug-glug-glug…
Beer rushes in through my butt.
Thanks to the master’s magic, I don’t get drunk.
But my belly keeps swelling bigger and bigger.
“Ugh, ughh!!”
“If you strain, your stomach will tear. I’ll put in at least three liters.”
The master’s low voice
“Gag!?”
A sudden wave of nausea hits me.
It feels like the beer is even backing up into my stomach now.
The back of my throat burns hot, and I feel like I’m about to throw it all up at any moment.
But not a single drop comes out of my mouth.
That’s also because of the master’s magic.
Today is my first time working in the main hall.
My brand-new maid outfit is really cute, but I wasn’t in any state to enjoy it.
Squelch!
“Yikes!?”
The hose was pulled out. But nothing comes out from my rear.
“This magic won’t be undone until you die or until closing time. Now, hurry up and deal with the customers.”
Saying that, the master went over to another beer girl.
Laughter from customers echoes from down the hallway. The sound of glasses clinking together too.
Hugging my heavy belly, I gently parted the curtain leading to the main hall.
At that moment…

“Eek!!”
One of the beer girls came running straight toward us.
Thud!
Before I could react, she crashed right into me.
We both fell hard on our butts.
Squelch! Glorp, glorp, glorp!
“Hyuh!?”

Suddenly, an intense pressure surged up in my belly.
With a bubbling, frothy sound, my stomach swelled up all at once from the inside.
The shock from the fall must have caused the carbonation to suddenly fizz up.
Suddenly, a memory flickered through my mind—something from long ago.
Back when I followed Master to a tavern near our house…
I remembered the moment when the owner dropped a leather bag filled with beer.
Pop!
The bag puffed up and then burst open, spraying its contents everywhere.
“Ha! Cheap ones always break so easily,” Master had said, and the owner just smiled wryly in response.
I remember laughing too, standing right next to Master.
Now… am I about to burst like that bag?
Squelch! Glorp, glorp, glorp!
“Hyuu!? ”
Desperately trembling, I wrapped both arms around my belly.
Glorp! Gloroborobo!!
“Gobo—ugh, aaagh!! N-no… stooop!! I—I can’t—gahhh!!”

It was the beer girl I’d crashed into, crying out in panic.
Her stomach was swelling up right before my eyes—so quickly I could actually see it growing.
Just like that leather bag the shopkeeper dropped back then…
But this time, it wasn’t a bag—it was a living girl, staring at me with desperate, pleading eyes.
I rushed over to her in a panic.
“No… no, please… I-I’m not… ready… ugh!!”
She tried to stand, but her rock-hard, bloated belly kept her pinned down.
There were still hours left before closing time.
In this state, there’s no way she could keep working as a server.
She knew it too—it was the rule of the tavern…
I felt bad for her, but I had to hurry and get her to the bursting room.
“The Bursting Room”
It’s the place where beer girls go to meet their end.
When they reach their limit, it’s the rule—they have to make their way there on their own.
I supported her by the shoulder and somehow managed to help her to her feet.
Creak… creak… creeeak, creak…
Ominous creaking sounds—just like a leather bag about to tear—were coming from her swollen belly.
She took a step forward.
“No… I don’t want to… It hurts… I’m scared…”
Her face was scrunched up with tears.
She may have worked as a beer girl, but in reality, she was just an ordinary girl.
Her legs trembled as she clung to me tightly, like a frightened little child.
I kept encouraging her—telling her it would be okay—as we slowly walked together.
But that was a lie.
Nothing about this was okay.
Still, there were no other words I could say.
The bursting room was just ahead now.
Just a little farther… just a little more, hang in there.
Rip!
“Nooo!!”
A wet, tearing sound rang out from her belly—like fabric being ripped apart.
A dark red stain slowly spread across her serving uniform.
Ah, wait!! Not here—!
SPLAT!!
“Gubuh!!!”

A heavy, wet burst echoed through the room.
Red liquid sprayed like mist, staining her maid outfit.
The sharp scent of blood and the bittersweet aroma of beer rushed into my nose all at once.
SPLAT SPLAT SPLAT!!
Foaming, dark red liquid and bits of flesh poured out from under her skirt.
I caught her collapsing body and gently laid her down on the floor.
Her belly slowly deflated.
Wanting to help her let it out as quickly as possible, I gently pressed my hand against her belly.
“Gop… goboh!!!”
A torrent of dark, bloody beer gushed out of her mouth.
The magic had been broken.
Gasp… gasp… gasp…
The hands that had been clinging to my arm gradually lost their strength.
Fingers that were so warm only moments before turned as cold as stone.
“………………”
This is our fate.
Next time, it might be me.
But for now, all I could do was stay by her side as she passed away.
I just hope… that in those last moments, she knew she wasn’t alone.
