Setting Pet Rules
Setting Pet Rules

Moving on all fours required far more stamina than she had imagined.
Seoyun, who never exercised and had a weak skeletal structure, felt an aching pain throbbing in her limbs, waist, and pelvis as she sniffled back tears.
"Huaa... haa..."
Seoyun wriggled her buttocks as she crawled diligently across the floor.
Each time her sagging breasts swayed like pendulums, the strain on her limbs intensified.
"Junwoo oppa... stop... please..."
Even as she tearfully pleaded, Junwoo did not stop.
Only after he felt she had moved enough to satisfy him did he halt his steps.
"How is it? Feeling good?"
"Huu..."
"You'll be crawling like this every day from now on, so get used to it. Understood? Now kneel and sit."
"Hng... uung..."
Seoyun obediently knelt and sat down.
As her knees, which had borne her weight, were freed from the pain, a tingling, cramp-like soreness rose up.
"Ugh..."
Seoyun frowned, tapping her knees with her clenched fists.
Junwoo, holding the leash in his hand, was still just smiling brightly.
"Seoyun-ah, do you know how incredibly cute you look right now? You really look like a puppy."
"Uu..."
"I love it so much. So, am I your Master from now on?"
Junwoo lightly shook the leash as he commanded.
"Say 'Master'. Look at me lovingly while you say it."
"Th-that kind of thing... I don't want to..."
It was Seoyun who had said she would go along with the pet play.
But even so, she didn't want to tolerate this kind of human rights violation and trampling of her self-respect.
"A-yuk!"
Junwoo yanked the leash with all his might, toppling Seoyun over.
He expressed his anger by pressing his bare foot down firmly on her head as she lay face-down on the floor.
"Haa~ Seoyun-ah, it seems you still don't understand. Do you think this situation is a joke?"
"Hng... N-no..."
"Do you think it's over just by humoring my mood? Unfortunately, that's a huge miscalculation. I want to possess everything about you, I want to spend my whole life with you. How many times do I have to say it for you to understand?"
"Hng... I was wrong..."
"You were wrong? Then why do you keep being defiant and not doing as you're told?"
"Uuuuk..."
Junwoo pressed down on Seoyun's trampled head, pushing it repeatedly as he vented his anger.
"If you had loved me from the start, this wouldn't have happened. You were the one who refused to be my girlfriend first, weren't you?"
"I'm sorry... I'm sorry... Hng..."
Seoyun, who hated the pain, burst into tears, repeating apologies she didn't mean.
She didn't want to talk back pointlessly and end up getting choked unconscious like before.
"If you keep acting like that, I have no choice but to get angry."
"Hng... I'll behave from now on... Really... Hng..."
"You promise?"
"Uung..."
As the foot crushing her head lifted, Seoyun straightened her back and sat up, staring intently at Junwoo.
"Hurry up."
"Eut..."
The upward gaze wasn't exactly pleasant.
With lips stuck together as if glued, she barely managed to part them and uttered the difficult word.
"Ma... Master..."
"Ha-haht! Good, good."
The oppa who had been closer than anyone until yesterday had now become her Master.
Humiliation, shame, self-loathing, gloom...
Countless emotions mixed together, making her head spin.
"Uuuuk..."
"So this is how it feels. To have a pet."
Junwoo smiled and reached his hand toward her face.
He carefully peeled back the hair stuck to her skin with sweat and tears, tucking it behind her ears.
Sighing that it was a shame to ruin such a pretty face, he went into the room and returned with a single sheet of A4 paper and a ballpoint pen.
"Here. Take it."
After placing the paper on the living room table, he handed the pen to the kneeling Seoyun.
What on earth was he telling her to do with this?
Write a letter of reflection or something?
She had no idea what he was thinking.
"Seoyun-ah, what do you think a pet is?"
"Huh..?"
Junwoo suddenly asked a question about the 'definition of a pet.'
An easy yet difficult question.
Seoyun hesitated, unable to answer.
"Say it quickly."
"Well... I mean..."
What is a pet?
Literally, it meant keeping a beloved animal by your side, cherishing it, giving it love, and spending a lifetime together.
But the pet Junwoo envisioned felt slightly different from what Seoyun understood.
"A pet is... a being that absolutely obeys its Master no matter what, gives its Master eternal love, and only looks at its Master."
"Uung..."
"Why, isn't that how dogs usually are? They only look at their Master, wag their tails happily, and stick out their tongues and smile like fools no matter what's done to them?"
"Yeah... that's right..."
Seoyun recalled the image of a dog in her mind and nodded in agreement.
"So, I want you to become like that too."
"Huh..?"
"To absolutely obey me, to love me, to only look at me. It's not a difficult thing, is it?"
"..."
Seoyun remained silent, bowing her head.
She could easily whisper words of false love, but what Junwoo wanted wasn't that kind of half-hearted acting.
"Hik..!"
Junwoo's hand rose above Seoyun's spaced-out head.
Even though he was just stroking her hair as usual, Seoyun felt a chilling shudder run down her spine.
"Seoyun-ah, why aren't you answering? Do you want to be punished?"
"N-no... It's just... I mean..."
Seoyun flustered, on the verge of tears.
She must have been feeling dizzy.
"Forget it. I know exactly what you're thinking. They say everything is difficult at first, right? You'll be fine once you get used to it."
"Uung..."
"Today is the monumental first day as a pet, isn't it? We'll start training later; for today, let's set the rules you must follow together."
"Huh..? Rules..?"
Seoyun, held by the leash, was dragged to the table and forced to kneel.
A single sheet of pure white A4 paper with nothing written on it.
Junwoo tapped the paper with the tip of the pen.
"Write it down."
"What... should I write..?"
Seoyun, clutching the pen with both hands, asked back with frightened eyes.
"Write down the rules you think a pet should follow. I'll actively accept them."
"Okay..."
Rules a pet should follow..?
Seoyun pictured a cute little puppy in her mind.
Would a beast that doesn't understand language even comprehend rules being discussed?
What should she write to be correct?
What did Junwoo truly want?
"Why? Don't know?"
"Uung... I don't really know."
As she held the pen and spaced out for a while, Junwoo, unable to watch any longer, sat down beside her.
With one hand still gripping the leash, he used his other hand to snatch the pen and began writing directly.
[Rules Pet Seoyun Must Follow]
Junwoo wrote the title in large letters and immediately wrote the number 1 below it.
"Watch closely and remember."
"Okay..."
The first rule was control over language.
It was the most basic of basics, absolutely necessary for the Master-pet relationship.
"I'm one year older than you, right? It's fine to use casual speech as close friends, but that was when we were childhood friends. Now we're in a pet and Master relationship, so you must use honorifics thoroughly, okay?"
"Uung..."
Seoyun thought she could easily do that much.
Given the age difference, using honorifics was only natural.
The second rule was control over titles.
Since he had become the Master, calling him Master was only natural.
But Junwoo forced her to attach the title 'Master' not only to their usual conversations but to every word that would come from Seoyun's mouth from now on.
It was unacceptable for a pet to walk bipedally like a human.
It was fine outside, but inside the house where the two were together, moving on all fours was the absolute principle.
It made no sense for a pet to wear human clothes.
Junwoo made nudity the principle, and of course, from the involved party's perspective, it was unacceptable.
"No, this is..!"
"Why? Do you have a complaint?"
"Well... of course..."
She had a lot she wanted to say.
However, none of those words made it past Seoyun's lips.
"It's a rule only allowed inside the house. A rule that only applies between just you and me. That much is okay, isn't it?"
"It's not a matter of being okay or not..."
"Are you embarrassed? It's fine. Don't be embarrassed in front of me. I've already seen everything there is to see and done everything there is to do."
"Uu..."
After forcibly tying her up and raping her, filming her with hidden cameras, making her show all her shameful states...
How could a sex criminal have the audacity to say such things so boldly?
"You don't like it?"
"Well of course... This is too much..."
"Too much? Too much? And here I am trying to be as lenient as possible?"
"Huh?"
"I told you. It's a rule that only applies 'between you and me.' Didn't you understand?"
Junwoo sharply yanked the leash he was holding.
Seoyun's body swayed, and she ended up in a position clinging to his body.
"Seoyun-ah, do you want to live naked in front of other people too? Do you want to crawl around like a dog outside and show yourself to all the strangers? Is that what you want?"
"N-no..! Th-that kind of thing..."
"Why? Are you going to say you don't like it again? That it's too much?"
"A-yuk!"
The repeated timid resistance.
Junwoo, who could no longer end it with a warning, reached his hand toward Seoyun's face.
"Hiiuk..."
Junwoo, with his palm open, lightly tapped her cheek a few times.
It was a threat that he could hit her anytime if he wished.
