Chapter 125: Side Story - Younger Sister (8)
“The reviews were definitely bad, and sure enough, it wasn't very good.”
The movie had ended. They had stayed through the credits and the post-credit scene, and were now making their way out as the lights flickered on in the theater. Suddenly, Kang Yu-jin heard a bright, chirping voice brush against his ears.
“Really? I thought it was okay.”
“The action was lackluster, and the storyline wasn't very convincing. It felt a bit… preachy, don't you think?”
The owner of that chirping voice wasn't his sister. Rather, it was a petite woman walking beside her with an innocent face—someone Kang Yu-jin was already acquainted with.
In fact, back when their incestuous relationship was in full swing, she was someone who had been ‘caught up’ in their antics several times.
Standing barely over 150 centimeters tall with a naive face and an even more naive demeanor, she was truly something else. Kang Yu-jin and Kang Yu-ri had used that innocence multiple times as a ‘spice’ to heighten their own thrills.
And if someone were to ask if he felt guilty about it, he would have no choice but to answer that he did.
Whether she knew it or not, Kang Yu-jin and Kang Yu-ri had flaunted their unspeakable behavior in front of this girl, Shin Ye-ji, in all sorts of ways.
Even if she herself remained oblivious.
So, as he left the theater, Kang Yu-jin looked at the apologetically chatting Shin Ye-ji, but he couldn't do anything more.
This was because the man who appeared to be her boyfriend was casting a suspicious gaze his way.
In a way, it was only natural. To any sensible person, there was no reason for a brother and sister to go to the restroom together, nor was there any logical explanation for the faint, musky scent clinging to them afterward.
But he didn't ask. Kang Yu-jin had a vague idea why.
It was too nonsensical to even bring up, and even if he did, they would obviously just deny it.
Or perhaps, his imagination simply didn't stretch that far.
That was the norm, after all. It wasn't easy for a normal person to imagine that a brother and sister were involved in an incestuous relationship.
Grateful for that fact, Kang Yu-jin followed them out of the theater and into a restaurant.
“Since we ran into each other, dinner's on me.”
“Oh, really? Thank you so much!”
“Thank you.”
Buying dinner for his sister’s friend and her boyfriend was something an older brother would naturally do, so no one suspected a thing.
However, there was a dark intention behind the gesture.
A dark, twisted intention that only Kang Yu-jin and Kang Yu-ri could share.
Kang Yu-jin meanly bought the meal as a sort of self-granted absolution.
As they ate the food they ordered, they talked about how they had been doing lately.
While observing his sister and her friend, Kang Yu-jin subtly kept an eye on the man who was the friend's boyfriend.
Just how much has he noticed, and how will he act?
It seemed like he had picked up on everything there was to notice, yet he wasn't acting on it. He was either unsure, or he felt that he shouldn't act even if he was certain.
But Kang Yu-jin couldn't afford to care about that. He simply continued his meal quietly, and only after they finished and the sun had dipped below the horizon did he lead his sister outside.
“See you later!”
“Yeah, see ya. Call me~!”
His sister and her friend waved goodbye. Only after they had walked a bit further did Kang Yu-jin subtly take his sister’s hand.
Not in the way family members or close siblings might hold hands.
He interlocked his fingers with hers and let her link her arm through his, their bodies intertwining.
No, he even pulled his elbow away from his side slightly to make it easier for her to cling to him. In an instant, Kang Yu-jin transformed from a close brother into a lover.
“Oppa.”
Even the way she addressed him was purely intentional. The word, which could also be used for a lover, was uttered in a voice that was sweet yet familiar.
It was as if she wanted to evoke the feeling of being both a sister and a lover at the same time.
Because Kang Yu-jin knew his sister well enough to understand her intent, she deliberately rubbed her chest against her brother’s arm and whispered in a sugary voice.
“You had fun today, didn't you, Oppa?”
“Yeah, I did.”
There was no doubt about it. The intensity of what they had done in the restroom and the sheer volume he had released were on a level incomparable to their usual encounters.
It was overwhelming, to say the least. It was to the point where he wondered if she would have been pregnant long ago if it were always like this, and Kang Yu-jin was secretly worried.
“Don't worry, I already took the pill.”
“Really? Will your body be okay?”
“Mhm, I'm fine. Actually… I feel great.”
She certainly looked the part. Kang Yu-jin looked at his sister’s vibrant face, which seemed to have a literal glow to it, and then scanned their surroundings.
As the sun faded and night descended, the people walking by seemed to be either hurrying home or preparing to burn through the night.
The atmosphere was ripe, and the streets lined with bars were filled with boisterous laughter and the energy of passersby.
Kang Yu-jin leaned toward his sister.
“…Right here?”
His sister spoke with a smirk. Kang Yu-jin quirked an eyebrow.
“You don't want to?”
“It’s not that I don't want to.”
“Then why not?”
“I said no.”
His sister spoke mischievously, drawing out her words. Kang Yu-jin realized that her "no" wasn't a real refusal.
Rather, it was a desire to provoke him, wanting to be taken somewhat forcefully.
How did she end up such a masochist?
He suspected that what they did during their first time was likely the cause, but he didn't know how to turn back time and undo it.
There was only one thing Kang Yu-jin could do now: accept the past and focus on the present. Kang Yu-jin leaned in, and while Yu-ri squirmed as if trying to pull away, she didn't actually retreat or push him back.
The hand she placed on his chest felt more like it was pulling him closer than pushing him away, and her face, which didn't flinch as he approached, was filled with excitement despite the words coming out of her mouth.
“Ah, no. I’m going to get kissed by my Oppa. I feel like my own brother is going to kiss me all over, deeply, like a lover.”
It was absurd to hear her giggle like that, but Kang Yu-jin didn't laugh. He pressed his lips against his sister’s.
He tilted his head as their lips met, grabbing her wrists and pulling them down, passionately mashing his lips against hers with his eyes closed.
It was a lover's kiss performed without any regard for their surroundings—or rather, performed as if for the world to see. An intense display of affection that could only be described as a French kiss.
Within it, his sister gasped. Her breathing grew ragged, and she let out a weak moan as if feeling the fluid leaking between her stockings and underwear as her body twitched.
Her insides, stimulated to the point of aching, repeatedly contracted and relaxed even though nothing was there, and her stomach writhed as she pressed against him. She was already a female completely primed for him.
Looking at his sister, Kang Yu-jin felt the suppressed desire burning in his gut. It was the dark desire that treated her not as a sister but as a woman, the one that had driven him to use her body however he pleased until now.
Despite it being incest, despite it being a relationship with the sister he had practically raised, it was a dark lust that made him undeniably aroused. Kang Yu-jin did not deny that desire. At least, not in this moment.
And so, the messy kiss did not stop despite the comments from those around them or the presence of people passing by. Instead, he went further, thrusting his tongue deep into his sister’s mouth.
“Nng, hng, chuup.”
When he narrowed his eyes, he saw his sister’s face. Her face was flushed red as she sucked on his tongue, swallowed his saliva, and let out moans with every gulp, her captured wrists twitching as she repeatedly clenched and unclenched her hands.
She was unbearably lovely. Kang Yu-jin was so aroused he felt like he wanted to do it right there, but he forced himself to hold back.
This excitement was intense enough to carry all the way home, and home wasn't that far from here.
They could continue this at the house.
So, Kang Yu-jin subtly moved his knee to rub against his sister’s crotch, then pulled her wrists to wrap them around his waist as they exchanged a fierce kiss.
It was just as their tongues, which had been coaxing each other in a tangled mess, were about to part.
A thick silver thread of saliva stretched between them, and Yu-ri’s hazy eyes turned toward her brother.
“You… pervert….”
It was a ritualistic remark, uttered out of satisfaction at having been kissed so intensely and possessively in such a public place.
Come to think of it, it was something he had heard since they first started this kind of relationship, so Kang Yu-jin simply shrugged.
“From where I’m standing, I think you’re just as bad, Yu-ri.”
Kang Yu-jin pulled his damp knee away from her crotch, and Kang Yu-ri smirked even as her face turned red.
“It’s a physiological reaction. It’s because Oppa kissed me with that handsome face and rubbed me so much… that I ended up like this.”
“Is it my fault?”
“Yeah, your fault. Zero to a hundred. Life sentence.”
“Whatever, seriously.”
Kang Yu-jin let out a hollow laugh and pulled his sister into an embrace. While she buried her face in his chest and rubbed against him to find her composure—
Kang Yu-jin, realizing he could no longer hold back, whispered.
“Then, shall we head home? At home, we can…”
“…Yu-ri?”
His words were cut short the moment Yu-ri pulled away from his embrace and her expression went blank.
That expression changed in an instant. It shifted into something close to terror. Sensing the gravity of that look, Kang Yu-jin’s eyes widened and he strained his ears.
A familiar, bright voice had come from right behind his back. Kang Yu-jin turned his head in a panic, and there stood the girl they had just parted ways with.
A girl who could only be described as such, with her tiny height and small frame—Kang Yu-ri’s friend.
An innocent, lively, and vibrant girl.
And perhaps, the pure-hearted girl who had watched them for a long time without ever knowing about their incestuous secret.
Kang Yu-jin and Kang Yu-ri both looked at her—at Shin Ye-ji.
And Shin Ye-ji, her eyes wide with shock, stammered with her mouth agape.
It was a situation where no one knew what to say.
The three of them stood frozen, doing nothing but exchanging glances.
