Slave Water Tank (Chapter 1)

【Household Slave Water Tank】
Because their bodies are soft, young individuals are often chosen for this role.
Three are assigned to each household, and they store rainwater and other water in their bodies to be used as household water.
The end of the hose splits into three, so the water pressure is evenly distributed among the three.
For this reason, during sudden heavy rain, it is common to have one small individual among them as a kind of “safety valve.”

【Chapter 2: The Storm】

Crash! Whoooosh! Rooooaaar!! (A torrential downpour)
As it grew darker, lukewarm water poured down from the sky without mercy.
The poorly-drained soil was quickly swallowed up by the rising water.
Just as Master said, the heavy rain had arrived.
“Haa… haa…”

My stomach was filled to the brim in an instant.
Just breathing made my belly swell and it hurt.
“Hii… hii… fuu…”
I tried to steady my breath and calm myself down.
The skin on my abdomen had become so thin, it felt like even a slight touch might tear it open.
From a short distance away, I could hear Emma and Serina’s voices.
“Haah, haah, my stomach… can’t take any more…!”
“Emma… don’t tense your belly… please… otherwise, Rina will…”

The two of them were holding as much water as they could for my sake.
If this keeps up, their lives will be in danger…
Hurry… I have to become the safety valve… now…!

SPLAT!!!
“Aaaghhhh!!”
Suddenly, a loud bursting sound and a scream echoed from right beside me.

Startled, I turned around to see a young woman curled up small in a pool of blood.
“Noe—Noelle!!”
It was my friend Noelle, who had been serving as the safety valve beside me.
Her naked body was being tossed about by the stream of water gushing from her belly.
Some Masters don’t allow us to wear clothes at times, so that the safety valve can be activated right away.
Around her, two others who were also connected as slave tanks could be seen.
“Noelle!! Hang in there, Noelle!!”
“Master!! Noelle… Noelle is… hurry!! She’s going to die!!”
choking, coughing It… hurts… I don’t want this… ahhh…
With wounds like that, Noelle wouldn’t make it…
Even though she was my friend, all I could do was watch.
choking, gurgling “Hh— h-hurts… kill… me…”
Her moaning burned into my ears and wouldn’t leave.
Please, stop…!
All I could do was pray for Noelle to find peace soon.
creak… creak, creak!
“Ugh!?”
An awful creaking sound came from inside my belly.
I must have unconsciously tensed my stomach.
I hurriedly tried to relax it.
No—no good… Even if I relax… it still feels like everything inside will burst out…
The pressure is incredible… no… I can’t hold it back anymore!!

SPLAT!!!
“Ugh!?”

…Huh…?
My body… it’s not… broken yet.
sob “Aaaah, it hurts! Help meee!!”

A scream from Karen echoed from the house across the street.
That was the sound of another one of my friends “breaking.”
“Nooo!! Mommmy!!”
Come to think of it…
Karen always talked about her mom.
Even before I came here, she truly believed, “My mom will come for me.”
“Mommy… Mom…” urp…

Just a moment ago, there was only the smell of rain.
Now, the stench of blood, vomit, and waste grows stronger and stronger.
Just a moment ago, everyone was chatting with me.
Now, all the filthy things that spilled out from our bellies are being washed away by the rain—as if nothing ever happened.
The world that once felt happy is now ruined—soaked and muddied by what was supposed to be a blessing: the rain.
All that’s left is to wait for my turn.

Creaaak!! Creak, creak, creaaak!!
“Nnngh!?”
M-my stomach…!? I can’t take this anymore… really…!
It’s okay, it’s okay. Calm down, me.
Deep breaths.
“Hah, hah, hah…”
I can’t get much air in.
But slowly—open up my abdomen.
Relax my stomach, let it swell up like a balloon.
Creaaak, creaaak, creaaak!!
“Gyaaaah!!”

I’m scared.
I can’t stop shaking.
Noel, Karen…
All of them suffered so much, screaming at the top of their lungs…
But not one of them ran away from their duty.
They fulfilled their roles and protected the others—almost as if it was the most natural thing in the world.
B-but… for what…?
Creak, creak, creak!!
“Nnghh!!”
A warm liquid spreads around my waist.
The fear crawling up my spine is even stronger than the pain.
This is reality—this is my role as a safety valve.
But… but… I want to live.
Even if it’s just for a moment longer, even just one more breath—I want to stay connected to this world.
I don’t want to die… I don’t want to die like that!
Anything but that ending… No, never!!!

SPLAT!!!
“Urgh—ghhh!!”

…Huh?
S-Seri…na…?
The next moment, the pressure squeezing my stomach suddenly vanished.
Cold air rushed into my lungs, and all the strength drained from my body.
But that relief was immediately erased by an overwhelming stench.
“Uweh!! Gweh—ugh!! Haaa—haa—…”
Emma’s and my water washed away so many precious things from Serina’s belly.
Serina twisted her face in pain, glaring at me.
I was frozen with fear—my legs wouldn’t move.
What do I do…
I don’t know what to do…
“Lina, hurry!! S-Serina… please, quick!!”
Emma’s desperate scream.
I staggered closer to Serina.
The stench grew stronger and stronger, stabbing at my nose.
“Li…na… Lina…”
A trembling voice; she was desperately trying to tell me something.
Gush!
The moment I leaned in close, a warm liquid splattered on my cheek and lips.
“… … …”
“Serina…! Serina!! Don’t go yet! You have something you want to tell Lina, don’t you?!”
My thoughts kept swirling: I failed in my role as a safety valve.
No… I have no strength left…
My vision grows darker and darker…
Thud (Lina collapses)
“Lina!? Why you too…? Noooo—aaaaaahhh!!! Somebody—please!!”
