Chapter 117: Side Story - Younger Sister (1)
Kang Yu-jin.
Having been discharged from the military and choosing to return to university, he had grown up in a perfectly normal, fairly well-to-do household. In truth, he considered himself a rather ordinary and uninteresting person.
Unlike those who were extraordinary or interesting, Kang Yu-jin didn't have a single exceptional or unique trait.
He wasn't particularly talkative, nor was he overflowing with self-confidence or talent.
It wasn't as if he was a great listener, either; he was simply the kind of person who was mediocre at most things.
Certainly, the fact that he did many things and had many skills was a strength, but those weren't innate talents—they were things he had acquired later in life.
In reality, he had no particular dreams or visions, nor did he possess any grand convictions.
He was just an ordinary young man.
Or rather, perhaps he wasn't quite so ordinary. Yu-jin was pondering this in his studio apartment.
With a smartphone in one hand, he moved his thumb silently and mechanically, navigating freely through a sea of short videos designed for dopamine hits.
He was the picture of an ordinary yet unordinary young man who could be found anywhere in the world.
After some thought, he concluded that his lack of ordinariness—his uniqueness—didn't stem entirely from himself.
The reason lay solely with the family member right next to him.
Wearing dolphin shorts, her legs were lifted and draped over Yu-jin’s.
One arm was wrapped around Yu-jin’s waist, while her other hand held a smartphone.
With her chin resting on Yu-jin’s chest, she stared silently at her screen.
Her hair, tied to the side, added a touch of freshness to her cute features.
“Oppa, aren't you staring a bit too much?”
It was his younger sister, Kang Yu-ri.
She spoke playfully with a smirk, tightening her arm around her brother’s waist and pressing her giggling face against his chest.
To an outsider, they might seem far too intimate, far too close for siblings.
But as far as Yu-jin could remember, Kang Yu-ri had always been like this.
She was unreserved and got along well with everyone in the family.
She was a clever and lovely girl who made friends easily and actively used her cuteness to her advantage.
At the same time, she was the reason Yu-jin had begun to consider his recent life as anything but ordinary.
To Yu-jin, she was an exceptionally close, intimate, and unreserved younger sister. The youngest who hogged all the affection.
Yu-jin stiffened as he felt the arm around his waist move, her hand slipping inside his pants.
“…Yu-ri.”
“Hmm? What is it?”
Normally, such a situation would be followed by shock and reprimand.
But Yu-jin merely called her name as if quietly admonishing her, letting out a deep sigh at her feigned innocence.
It was a behavior he had already grown accustomed to, and deep down, it was an act Yu-jin himself had desired too much to truly scold her for.
“Is it not allowed?”
Yu-ri looked up at her brother with wide, shimmering eyes, as if pleading with him.
Lamenting the fact that he was already used to this, Yu-jin quietly nodded.
That was the reason why the utterly ordinary Kang Yu-jin had recently come to think of himself as unordinary.
By living with his sister, they had become more than just brother and sister.
Yu-jin took a moment to wonder how it had ever come to this.
*
It all began back when they were still in school.
The family was wealthy and lacked for nothing, but things were a bit strict.
This was especially true regarding schedules and academics, though Yu-ri was the sole exception.
‘Mom, I’m tired and I want to quit. Can’t I?’
By utilizing her cute face, gentle demeanor, and sociability, Yu-ri had managed to escape their mother’s hardcore academic plans early on. Yu-jin, however, had not.
Between fencing, swimming, studying, and various other activities, Yu-jin had been under a great deal of unconscious stress, and that stress inevitably manifested as sexual desire.
In a way, it was a natural progression that he was eventually caught by Yu-ri while relieving that pent-up desire.
‘…Oppa, what are you doing?’
Yu-ri had asked with a somewhat chilling aura. Facing her, Yu-jin had hurriedly pulled up his pants.
Dizzy with the thought that he was well and truly screwed, Yu-jin tried to come up with an excuse, but no excuse would have sufficed.
Yu-ri had bolted out of the room, and Yu-jin hadn't been able to chase after her.
He wondered what would happen now—whether he, the only male in a house full of women, would face a sort of persecution.
If he had been caught by Kang Yu-min, he would have just been teased and that would be the end of it. Why did it have to be Yu-ri?
As Yu-jin agonized over these thoughts, Yu-ri had come to his room in the middle of the night.
‘Oppa, is it… is it really hard for you? That thing?’
Back then, Yu-ri had spoken shyly. It was a far cry from her current self, who boldly reached into her brother’s underwear and touched him without permission.
‘Should I help you…?’
It was only much later that he realized her shy question was part of a seduction, a calculated move.
But it was also a natural progression for the red-blooded Yu-jin to fall for Yu-ri’s temptation.
‘Thinking back now, I should have behaved like an older brother.’
But it was too late. From that moment on, Yu-jin had crossed the line with Yu-ri, and it had continued to this day.
Through his military service, through Yu-ri becoming an adult, through her graduating university and getting a job at their father’s company.
And now, Yu-jin was living alone with his sister, Yu-ri, in the studio apartment he had secured upon returning to university.
Contrary to the assumptions of his mother and eldest sister—who thought there would be no issues if the siblings lived together—Yu-jin was currently engaged in a cohabitation that was as debauched and unwholesome as could be.
He had no complaints about this life.
In fact, he thought it was a rather good life.
He did his assignments, attended school.
He came home to eat with his sister so he wouldn't be lonely, and they often went out to eat as well.
The feeling of not being alone, no matter what he did, was wonderful.
Above all, there was the fact that this incest was quite a pleasurable act.
Unlike when they lived at their parents' house, the sense of depravity or danger was less intense, but this had plenty of its own advantages.
For instance, they could do it freely without being anxious or scared.
And it was nice to be able to do it at more flexible times without having to worry about others.
Yu-jin looked at his sister, who was happily licking and sucking his cock, savoring the afterglow now that everything was finished.
That was certainly the case.
And yet, something was weighing on his mind.
At his steady downward gaze, Yu-ri looked up. She still held her smartphone in one hand.
“What is it?”
Her upward gaze was soft. It was so full of affection that one could sense the love she was sending just by looking at her.
Yu-jin didn't dislike it either. What brother would dislike being loved by such a cute younger sister?
The problem lay in this twisted relationship. The fact that she was shaking the base of his cock while looking up at him with those eyes.
The thought suddenly struck him that this was very, very wrong. However, having just indulged himself, he couldn't bring himself to say it. He knew this was just part of the post-nut clarity and that he wouldn't be thinking this way shortly anyway.
Still, Yu-jin truly felt that way.
That this relationship couldn't possibly end well.
It would be a problem if they were caught, and a problem even if they weren't.
What would they do when they reached marriageable age? It was clear this would have nothing but a negative impact on their futures, yet he had no idea when they could ever bring this to an end.
As various worries filled his mind in a dizzying whirl—
“Ah.”
“Hmm?”
Yu-ri suddenly stopped mid-suck. Still naked and lying between her brother’s legs with her smartphone in hand, her eyes trembled slightly.
What is it? Did a war break out? While Yu-jin wondered, Yu-ri let go of his cock entirely.
“Oppa.”
“Yeah? What? What is it? What’s wrong?”
“The family group chat.”
Yu-jin barely managed to rouse his hazy mind. Following his sister’s urgent words, he picked up his smartphone.
An all-too-familiar profile picture and face, accompanied by an all-too-familiar tone, appeared in text form and filled Yu-jin’s vision.
“Shit.”
[Noona: I think I’ll be dropping by this evening. I’ll give you some time to clean up beforehand (cute emoticon)]
[Noona: You’re in trouble if it’s a mess?]
At the bolt-from-the-blue news, Yu-jin and Yu-ri naturally scrambled to their feet.
“Oppa, what about the condom?”
“Just shove it in the drawer!”
“No, the used one! The one we just used!”
“Huh? Oh, that… the trash can….”
“What if she finds it!”
“I don't know! The toilet? No, the toilet will get clogged. Then….”
“I’ll just put it in your bag for now!”
“Wait, Yu-ri? Yu-ri?!”
Amidst the chaos, they barely managed to clean everything up before Kang Yu-dam arrived.
And that, at the same time, proved something else that made Yu-jin even more uneasy.
It was proof that these siblings had become completely accustomed to this taboo and had become experts at destroying evidence to avoid being caught.
With a heavy heart, Yu-jin greeted his eldest sister as she entered their studio apartment.
Regardless of his unease, a part of him desperately hoped they wouldn't be caught.
Even so, Yu-jin was certain. There would be no problems, his sister wouldn't notice a thing, and once she left, Yu-ri would cling to him again as if they were lovers.
Is it really okay to go on like this? Just as Yu-jin was worrying—
“Hmm? I smell something musty?”
Despite all his ruminations, Yu-jin found himself breaking into a cold sweat.
