Pet Registration (2)
"Euut..."
Buried inside the machine, Seoyeon twisted her arms and legs.
She tried to escape somehow, but she was hopelessly outmatched.
The seamless, firmly locked metal restraints offered no way for a human's strength to break free.
"Hueuk..."
In the end, her body was fixed in place with her legs spread wide in an M-shape and both arms extended to the sides.
Inside the dim machine, all she could hear was the nauseating whir of its machinery.
Various cables were revealed whenever the sensor lights flickered irregularly.
"What on earth are they doing..."
[Hello.]
"Hik!"
Startled by the sudden voice, Seoyeon jumped.
The echoing voice in the cramped space felt as though it were burrowing straight into her brain.
[Pet Registration will now begin. The process will take approximately fifty minutes.]
"Uu..."
[We will begin by recording and registering the basic entries one by one.]
No sooner had it finished speaking than the hand extended to the side spread wide open.
A machine grasped each finger individually and scanned Seoyeon's fingerprints.
It then scanned the shape of her soles, the structure of her mouth, and the size of her pupils.
"Hieuk..."
A subtle sensation felt in the darkness where she could see nothing.
It was a fear only someone who had experienced it could understand.
[Next, we will record the degree of breast compression.]
"Heue..?"
A thick glass plate approached from the front.
Connected to a cylinder, the glass plate pressed hard against her soft breasts.
"Kkeuuugh..! It hurts..!"
The glass plate continued pressing down until her lungs were compressed and breathing became difficult.
The scan was completed after blue light blinked repeatedly for about thirty seconds.
Her nipples, jutting outward, were bent in opposite directions and buried in her breast flesh, creating a ridiculous appearance.
A private shame that could never be shown to others had become one of the important pieces of data identifying Seoyeon's status.
[Next, we will record the shape of the female genitalia.]
"Ah, w-wait a seecond..."
Twisting her waist in resistance only wasted her strength.
Two robotic arms extended from above and pressed a thin, soft cloth against Seoyeon's pussy.
"Hiek..!"
The machine's sensation as it rubbed up and down to make the cloth adhere closely to her vulva sent shivers down her spine.
When the cloth coated with some kind of dye was removed, the shape of Seoyeon's pussy appeared in its entirety.
The shape of its slightly swollen mound resembled a freshly made coffee bean.
Between the faintly spread and compressed labia majora and the slightly parted slit, the shapes of her urethra and vaginal opening were clearly visible.
A humiliating pussy imprint, beyond mere vulgarity...♡
It became important data that would prove Seoyeon's existence for the rest of her life.
[Next, we will record the internal shape of the vagina.]
"Eet..?"
As definitive a means of identification as the shape of her pussy was the shape of the inside of her vagina.
Every person had different widths, protrusion shapes, depths, vaginal pressures, and so on.
"Ah, w-wait a seecond..."
A frightening mechanical sound came from somewhere, and a transparent glass dildo surged up from the floor.
After an appropriate amount of lubricant was applied to the smooth dildo, it slowly entered Seoyeon's precious opening.
"Hieeek♡"
Goosebumps rose over Seoyeon's skin in the darkness.
Something cold that had suddenly pressed against her lower body was forcing her opening apart and entering her.
Along with a chill cold enough to make her skin crawl, it stretched her vaginal folds taut.
"Eungueuk♡"
The pain was intense because of the aftereffects of her first experience.
No matter how much she struggled and thrashed in protest, her body could not move at all.
In the end, after swallowing the dildo deep into her opening, Seoyeon felt an intense pressure strong enough to stop her breath.
"Haa... Kkeuk..."
Pain? Pleasure?
Rather, the complete absence of sensation made her feel even more unpleasant.
The glass dildo remained fixed in place without moving, emitting blue flashes several times.
[Checking vaginal depth, maximum allowable width, and the shape and size of the protrusions.]
"Uut..."
The scan of the inside of her vagina, recorded as data, was grotesque, like a mass of living flesh.
Large and small protrusions packed tightly together writhed so intensely that they could have given her trypophobia.
The visual stimulation was the worst imaginable, but Seoyeon's pussy was unquestionably a top-tier specimen.
[Measuring vaginal pressure. Tighten the opening.]
"Kkeuk..."
[Relax again.]
"Huuu..."
[Tighten again.]
Following the cold machine's commands, Seoyeon repeatedly performed humiliating Kegel exercises.
The problem was that one more opening still remained to be registered.
[Finally, we will record the shape of the anus.]
"Hiek...♡"
At the same time as the dildo slid out, Seoyeon's posture changed.
The restraints holding her legs moved upward, folding her body in half at the waist.
"Eugeuk... It's uncomfortable..."
Even remaining still in this position made her back ache and left her breathless.
If she had assumed the position herself, she would have collapsed within ten seconds.
With her arms and legs restrained, escaping was impossible no matter how much she wanted to.
"Kkeuuugh..."
As Seoyeon uncomfortably squirmed, two robotic arms spread her buttocks wide open.
An instrument resembling a scanner blinked with blue light as it recorded the shape of her anus.
The degree to which it was spread, the number of wrinkles, the pressure of the sphincter, and even the locations of spots she herself did not know about.
It meticulously recorded everything, even the duration and movements of its vulgar little puckering.
[Next, we will record the anal mucosa and the degree of curvature.]
"Hiek..!"
A silicone dildo pressed against Seoyeon's anus.
Its oddly sticky and yielding sensation was intensely creepy.
Made of soft silicone, the dildo was as pliable as a water balloon and nearly two meters long.
It was thin enough to be inserted without much difficulty, but its length was the problem.
"Kkeueueueek..!!"
Just when she thought it had gone in far enough, it continued entering toward an even deeper place.
"Stoooop!!!"
The sensation of her intestines being scraped as though something were sliding through them sent a chill down her spine.
It felt as if a bowel movement she had cleanly expelled were flowing back up inside her.
The feeling was so disgusting that tears welled in her eyes.
"Haeuk..!"
Even a hole with no apparent end clearly had its limits.
The dildo stopped at the S-shaped curve of her colon and gently pressed against the intestinal wall.
"Kkehaaak..! It huuurts!!"
A sharp pain shot through her, as though her body had been pierced by a skewer.
The area below her navel hurt as if it were being torn apart, leaving her unable to scream properly.
"Kkeuk..! Hiek..!"
The dildo rocked slightly back and forth before suddenly pushing farther inside.
"Heueuk..!"
Once it found a path, there were no further obstructions.
The dildo continued pushing in, squirming inside her body as though swimming.
The unfamiliar sensation she was experiencing for the first time sent nausea surging up her throat.
"Uwek..!"
She could not see it, but by feel alone, it seemed to have filled her entire abdomen.
The dildo, inserted all the way to its base, slowly swelled and pressed against her intestinal wall.
"I... I'm gonna diiie..."
Seoyeon's eyes flew open from the tremendous pain.
Her body trembled as she let out a thin, ragged voice.
The problem was that as her intestines expanded, they pressed against the woman's weak point, the 'lubrication glands' located where they met the uterine wall.
"Hk... Ueuk...♡"
In her mind, which contained nothing but pain, an unpleasant pleasure began to creep upward.
Alongside the pleasure being forcibly drawn from her, her lower abdomen trembled as though she were about to pee.
"W-wait a seecond...♡"
Every time she resisted the foreign sensation in her buttocks and tightly clenched her sphincter, the pressure stimulating her lubrication glands grew stronger.
After puckering her opening several times and letting out moans, Seoyeon finally could not hold back and burst into a fountain.
"Kkeuk...♡"
Suaaah—
Clenching her teeth, she reached a cute little climax.
Streams of liquid sprayed in every direction, dirtying the inside of the machine.
Lost in the darkness, she could neither look at her own miserable state nor wipe herself clean.
"Hueuk... I want to diiie..."
She was completely helpless, unable to do anything.
The pressure crushing her intestines continued for more than a minute afterward.
[Registration is complete.]
"Ugeuk..."
The dildo, thin and limp like a deflated balloon, slowly withdrew.
The sensation of it scraping past her intestines remained horrifying.
[Finalizing registration...]
The shape of her intestines remained clearly imprinted on the hardened surface of the silicone dildo.
The bumpy surface of the intestinal wall, the angles at which the colon curved, the point where the tip had reached, and more...
Every detail was recorded without exception, becoming important data for her Pet Registration Certificate.
[Registration is finished. Your issuance number is 46L731B+021. We will now issue your Pet Registration Certificate.]
The difficult-to-memorize number was the registration number that identified Seoyeon.
Chak—
"Hik..!"
A metal choker containing a digital chip was fastened around her neck.
It clung tightly to her skin as though custom-made, becoming part of her body.
[This choker serves as a mark of a Pet and contains various functions.]
The choker contained small amounts of several different drugs.
There were concentrated aphrodisiacs, stimulants, anesthetics, and more, all of which could be customized at any time.
In addition to drugs, it also had functions such as electric shocks, psychological stimulation, and temperature changes.
[For example, some Pets break their chokers and run away. To prevent this, electronic chips are inserted both externally and internally.]
"Eh..?"
The external chip referred to the Pet choker.
Then what about the internal chip..?
The instant she wondered about it, Seoyeon felt a sharp pain in her buttocks.
More precisely, it was near the tailbone on the upper part of her buttocks.
