Livestock Prison (8): The Livestock Injection
"Huff... huff..."
Sweat poured down in rivulets, unbidden, from the sudden burst of exercise she hadn't done in ages. Every exhale brought the metallic tang of blood to her tongue. Her lungs burned like they were about to burst.
I'm... gonna die.
It was only natural to feel this agony after forcing herself into unaccustomed exertion all at once. And the moment her pace lagged even slightly, a stinging gaze bored into her. The source was the guard, Ibuki. That glare alone forced Saeko to push just a little harder. Was it sheer willpower? Or terror of punishment? Either way, she somehow completed all fifty laps, her body drenched in sweat, heaving ragged breaths.
By then, the guard had approached her.
"Good. For now, today's training is over. Head back."
Back. It surely meant the cell she'd been locked in earlier. Saeko followed the guard once more, her footsteps leading back to the very same prison she'd started in. Back then, shock had left no room to take in her surroundings, but after the vibrant colors of the outdoor yard, the drab, colorless gray concrete walls now repulsed her. The only non-gray hue was a sinister red scar etched into the floor—fresh scratches like tally marks for days served. And below them, a profusion of nail marks. Just looking at them conjured images of the torment endured by those who'd passed through here.
Yet even in such a space, Saeko returned without hesitation. Her body, soaked from running and aching with exhaustion, gave her no choice. The moment she stepped inside, she collapsed to the floor, doubling over instinctively. Wave after wave of fatigue crushed her. The cold concrete felt even more frigid now, mirroring her plummeting position in the world—no warmth to be found anywhere.
Can I really ever escape this place?
Gazing at the ceiling, a profound despair washed over her. Even if she did get out, the stain of being branded a convict would taint her life forever. Rage bubbled up—what had she done to deserve this horror? Who had orchestrated her downfall? But before the thought could fully form, icy water cascaded over her body.
"Wh-what the—?!"
Startled, Saeko whipped her head around. No one was there. Looking up, she spotted tiny perforations in the ceiling. The water must have come from there.
"What...?"
Then came a watery gurgle, followed by a voice.
"Tap tap."
"A voice?"
"Body cleansing commencing. Please extend your limbs and remain still."
"Huh?"
"Body cleansing commencing."
As if it hadn't even registered her confusion, another torrent poured down. The liquid was so cold it felt like it was slicing into her skin.
"Eek!"
That was the end of it—no more water. Just her body shuddering from the brutal chill.
Moments later, Guard Ibuki reappeared. Recalling the earlier "training," Saeko ventured a cautious question.
"Um... when can I get some clothes?"
Ibuki snorted at her polite tone.
"Clothes? For livestock?"
"It's just... a bit cold."
"Don't worry about that. You'll be heating up soon enough."
"Huh?"
Saeko couldn't make sense of it—no explanation for this sudden promise of warmth.
"Since it's your first day, let's just start with a shot."
"A shot?"
What kind of shot? Saeko still didn't understand. But as Ibuki unlocked the iron-barred door and stepped in, an inexplicable dread gripped her.
"Wh-why are you coming in here?"
It happened in an instant. Ibuki seized Saeko's arm.
"Better stay still. If you squirm, I have to give you two. And trust me, two isn't fun."
She held up a syringe filled with unidentified green liquid. It looked anything but beneficial just from the sight.
Saeko's face drained of color.
Mammary aphrodisiac stimulant. Commonly known as the livestock injection. Its official name was some lengthy English term, but everyone just called it the livestock injection.
The reason was simple: all livestock received it regularly.
The livestock injection wreaked havoc on hormones—specifically, altering female hormones to slowly reshape the body. It made nipples perpetually erect, kept the body in constant heat, and swelled the mammary glands. Because of effects like these, livestock cows received multiple doses a day. It was occasionally used for cosmetic purposes too.
And that very injection was now in Ibuki's hand.
"What... what is that?"
Saeko pleaded for an explanation, but Ibuki showed no intention of providing one.
"Just think of it as something all livestock have to get."
As expected, without proper explanation, Ibuki aimed the needle at Saeko's breast. Saeko struggled to resist, but it was futile. Her exhausted body stood no chance against the guard's trained grip.
"No, let go!!"
She screamed and thrashed, but to no avail. In moments, Ibuki plunged the needle into her breast near the nipple. With it came an itchy sensation somewhere deep inside.
Was it her imagination? After the injection, her breast felt itchy and swelling. She couldn't pinpoint the exact change, but her feelings weren't entirely wrong. Her body was growing inexplicably hot. Not imagination—sweat began trickling from skin that had been chilled moments ago. Her head burned.
What is this...?
It was arousal—what Saeko was feeling. Seeing it, Ibuki smirked.
"Perfect. Now, one last thing to fill you up."
Ibuki produced a black collar. At its center was an iron lock linking the chain. It had an analog feel, but inside was an unbreakable steel cord. Every prisoner in the livestock prison wore one. If they ever left without central control authorization, it would self-destruct—a fact unknown to the inmates. It ensured they lived solely as livestock within these walls.
Saeko, unable even to resist, sweated profusely.
"The drug's kicking in nicely. I'll check on you tomorrow, so rest up."
With that, Ibuki fastened the collar around Saeko's neck and shut the iron door.
Even as Ibuki vanished, Saeko's vision blurred. Her gaze wavered in an unfamiliar haze. She had no idea this was the onset of heat. Arousal led to estrus. Now her nipples began to itch—actually, her entire body did. The second spot to flare up was her crotch. Thanks to the injection, sticky love juices had started leaking from below.
Drip.
The fluid trickled down her labia, soon soaking the floor. It meant Saeko had entered full estrus—like livestock in heat.
I'm going crazy... I, I keep wanting to touch it.
An irresistible urge to rub her pussy freely welled up. Not just rubbing— she craved stuffing and pounding something inside. Her mind was consumed by it.
In truth, it wasn't just the injection. Unbeknownst to her, everything in the livestock prison contained trace aphrodisiacs. The water that washed her had some; the air pumped into every room was laced with it. This was an automated system even the guards didn't know about. Constant exposure for twenty-four hours would break any human, let alone livestock. For Saeko, freshly dosed, resistance was impossible.
In the end, her hand drifted unconsciously to her pussy.
"I... I shouldn't touch it."
If she masturbated now, it'd be admitting defeat to her lust. For Saeko, who still clung to her humanity, that was unacceptable.
