Chapter 10: Bad Friends (5)
Chapter 10: Bad Friends (5)
“Let’s keep this a secret from Sis.”
“We have to.”
“But in exchange… you know, right?”
I never imagined a day would come when I’d feel lust for Kang Yu-min. I felt a mix of miserable self-loathing and a subtle, fluttering excitement.
“…What, are you already in the mood?”
It was happening even now. As we showered together, Kang Yu-min smirked and reached for my lower half.
Seeing her skin, slick and glistening with water, and that vivid smile after what we had just done—my body couldn't help but react.
But if we kept going like this, I’d be pouring it out like a faucet turned on full blast until I collapsed from exhaustion. After a moment of internal struggle, I moved my hand.
Slap!
“…Ah, huh?”
Kang Yu-min stared at me blankly after I brushed her hand away.
Her expression looked incredibly pitiful and pathetic. It reminded me of the time I had pushed her away in the past.
I started to say something, then just let out a long sigh.
“We’ve already done it four times. That’s enough. I’m tired…”
At those words, the expression that looked like it was about to crumble vanished, replaced once again by a smile.
“Oh, is that it? I thought it was something else.”
Her beaming face was similar to our eldest noona’s, yet strangely different.
To think that the Kang Yu-min was looking at me and smiling like that.
The reality of it felt incredibly alien. I mean, what exactly had I done to cause this?
Sure, we had done it, but still…
I didn't know. For the first time in my life, I felt like I didn't understand the person known as Kang Yu-min at all.
Meanwhile, she just stared at me intently.
“Aren’t you staring a bit too much? Pervert.”
She said it with a bright grin.
“Calling me a pervert after we’ve done everything we just did feels a bit weird.”
“Oho, look at you talking back to your noona.”
“I mean, we did do it…”
“Quiet. Yuri or Sis might hear if they come back.”
Yu-min winked and handed me the body wash.
“Can you wash my back?”
“…Fine.”
I tried my best not to let my gaze drop as I squeezed the body wash onto the shower towel, worked up a lather, and began scrubbing her back.
On the floor, the fluids were being washed away by the constant stream of water.
The semen I’d accidentally spilled when Yuri arrived, and the pussy juice Yu-min had leaked.
And after that, all the cum Yu-min had drained out of me using her hands, mouth, and thighs.
It was all swirling down the drain.
But even if it all washed away into the sewer, what happened couldn't be undone.
Yu-min acted like she didn't have a care in the world, but I couldn't help but be bothered by it.
It would have been one thing if I could just brush it off as something that only happened in the game, but Yu-min and I had already touched each other in reality.
Even if we hadn't gone all the way, I had even creampied her.
In fact, it wouldn't have been strange at all to go straight to the bedroom and continue, but I was the one who stopped it.
Though it seemed like Yu-min was hoping for exactly that.
There were two problems.
One was that I didn't know when Eldest Noona would return, and the other was that I didn't actually want to go that far yet.
The fact that we had been bickering just moments ago acted as a psychological barrier.
Still, there was no taking back what had already been done. Knowing that, I sighed and meticulously washed her back.
Yu-min seemed to be in a great mood, even humming to herself.
I’m often told I’m dense, but in this case, it was impossible not to notice.
Maybe the reason she cried when I pushed her away back then…
And the reason she described it as emotional pain…
Maybe there was a reason for all of it? Even as I guessed at the truth, I couldn't bring myself to say anything.
Because once I asked, things would really…
No, let’s not think about it. I just focused on scrubbing the female body before me, lathering and rinsing repeatedly.
“Should I wash you now?”
“I have hands, don't I? Can't you see them?”
“There you go being a smart-ass again. After doing all that…”
Yu-min spoke with a hint of a pout. Looking at her, I felt an indescribable awkwardness.
The Kang Yu-min I had known my whole life wasn't this kind of person.
Did she get swapped out inside the game? Or was this not actually Kang Yu-min? Or was this whole situation part of the game too?
What if I was an NPC in a game and the admin was just feeding me data stimuli?
“Ow.”
“What are you thinking about so hard?”
“No, but did you have to flick my nose…?”
Even Yu-min didn't seem to have a clear grasp on how she should act. Part of her wanted to 'act like a girlfriend,' but aside from that, she seemed to be struggling with how to treat me normally.
“Anyway, it’s… well, it’s your fault…”
That’s why her words were so awkward. I rubbed my nose where she had flicked it.
She was trying to act cold and bicker like we used to.
But it was clear that it was impossible now. Eventually, I let out a sigh.
“Let’s just try not to overthink it and act like usual. So Sis and Yuri don't find out.”
“Uh, well.”
“What?”
“I think that’s going to be hard…”
Yu-min fidgeted, giving a bashful smile.
I was about to snap at her, asking why she couldn't do something so simple, but I closed my mouth.
I wanted to treat her coldly to prove that it wasn't hard at all, but…
“Yeah, it is a bit hard.”
Strangely, it was difficult. I felt a heavy sense of resistance.
It wasn't like someone was kneading my brain, and there wasn't one specific reason.
It was just the insight that if I acted like that and saw her reaction, I would feel miserable.
That’s why it was hard for me to be cold to her. It was probably the same for her.
To think that just mixing bodies would make things this difficult.
“Well, then… I guess we just have to try our best to act normal.”
“I don't have to do that in the game, right?”
“The game?”
“Yeah.”
“In the game…”
I didn't know exactly how the Family-Friendly Game was structured or what its principles were.
But it didn't seem like our physical bodies changed. In fact, I didn't even know what we looked like when we were inside the game.
Should I try recording it? I wondered, but I just nodded.
It didn't seem like anyone could see what we were doing from the outside.
“In there, you can do whatever…”
“Really? You said it, okay?”
Yu-min smirked and poked my chest. I felt a sense of foreboding and started to say something.
Regrettably, my intuition was spot on.
I realized it a month later.
That Kang Yu-min was in love with me.
One month. It had been a month since the first time I… well, did it with Kang Yu-min.
And looking back on the past month, I don't think it was an easy one.
Eldest Noona was busy. Quite busy, in fact, so she didn't show her face at home very often.
It was a stroke of luck for Kang Yu-min.
With Eldest Noona away for work and Yuri spending most of her time at cafes or study rooms with friends to prepare for the CSAT, Yu-min and I were left alone.
Yu-min and I did a lot of things together in the house.
When we woke up late, we ate together and showered together.
She had always been the type to barge into the bathroom even when Yuri or Noona were home, but when they were gone, it was even worse.
We didn't do actual insertion, but looking back, we did pretty much everything else.
Kissing was a daily routine. Yu-min, who loved everything from romantic and erotic kisses to playful ones, wouldn't be satisfied until we had exchanged enough saliva to make my lips feel swollen.
Her hands and mouth were already more familiar with my cock than my own hands were, and my tongue and fingers had perfectly learned every sensitive spot inside her pussy.
We would spend about an hour in the bathroom without even saying much.
It really felt like we had done everything except the final act.
And after spending intimate time together in the same bathtub, we would dry off and sit in front of the computer to play the game together.
The Family-Friendly Game. The name alone gave a vague hint of its purpose, and aside from the occasional forced incest, it was an excellent game.
Perhaps because it used technology that didn't exist in this world, it somehow knew how to send money even without an internet connection, and it provided a level of virtual reality that surpassed anything I’d ever seen. Even without the erotic elements, the game was fun.
We went on adventures in fantasy worlds, became a detective and assistant to solve cold cases.
We became mercenaries in a cyberpunk world and watched each other's backs, and leaned on each other's shoulders to sleep in a zombie apocalypse.
We had a great time. Even with the occasional incestuous acts.
Aside from that, the time we spent together was quite enjoyable.
It made me realize how little I actually knew about the woman named Kang Yu-min.
Yu-min was quite athletic, though not as much as Eldest Noona.
She wasn't the brightest and her learning ability wasn't great, but she picked up physical skills quickly. Even with marksmanship.
She didn't use guns much because she preferred physical combat, but she learned quickly and was a good shot.
Because she was simple and blunt, she didn't get scared easily, and because she cherished me, she was good at tanking for me.
‘…Jin-i, do you like me?’
She was also quite clingy and acted cute often.
It was a side of her I never knew. The question came while we were lying naked together, feeling each other's body heat.
Her hair was damp with sweat, and the question she asked while looking at me with eyes shining with excitement was filled with pure affection.
I grew accustomed to that side of her.
To the point where I felt a slight sense of loneliness when she wasn't around.
Yeah, who was I kidding?
I had fallen for Kang Yu-min. Probably not as much as she loved me, but still.
I had developed feelings for her. No man could resist being treated with such care and love.
I wondered how I had become a guy who loved his own sister, but if there was one consolation, it was that we hadn't done the final act.
It would be a total disaster if she got pregnant. Even with contraception, it wasn't 100%, and I didn't have the confidence to tell Noona that I’d been sleeping with Yu-min and knocked her up.
So, we didn't go all the way.
It was the same in the game. I felt that if we did it in the game, we would soon end up doing it in reality too.
Yu-min agreed, and while she intentionally avoided talking about the future, she seemed to secretly look forward to it.
A future where I couldn't hold back anymore and embraced her, getting her pregnant.
“…Whew.”
Thinking about it now, it was strange. My attitude toward Yu-min had always been aggressive and harsh.
Yet she loved me.
I wondered if that was just her type.
And it wasn't entirely baseless. Over the past month, Yu-min and I had done all sorts of things within the limit of not crossing that final line.
I’d shove it down her throat until she couldn't breathe, or I’d keep thrusting my fingers into her even when she begged me to stop because she couldn't take any more.
Even that final line… Yu-min’s words that it was okay because it was just a game were so tempting that I almost gave in several times.
It was a good thing I was stronger than her.
I blew on my iced cola and stared blankly out the window.
It was snowing.
The whole world was turning white.
Yu-min had left the house, saying she needed to go to the gym today. I was all alone.
It was December, the cold was everywhere, and Yuri had finished her CSAT and was awaiting graduation.
I sat there, staring out at the balcony.
The house was quiet. Amidst the overflowing thoughts in the silent yard, I was pathetically waiting for my lover-who-wasn't-a-lover.
We had never said the words, and we hadn't even confirmed anything, but she was essentially my lover—and my blood-related family.
I knew it was wrong, but I couldn't help how I felt.
I waited quietly at home, desperately hoping for Yu-min to return from the gym.
Maybe I should start going too. I have plenty of money.
It would be nice to go together.
I’d just have to worry about her constantly trying to do something erotic.
As I was lost in thought, I heard footsteps.
In a building where no one but our family lived, footsteps meant one of two things: a delivery person or a family member.
I looked toward the door, hoping it was Yu-min.
But I felt a wave of disappointment when I heard the familiar, leisurely sound of the electronic lock.
As the lock clicked open, I desperately tried to fix my expression.
Wait, why was I disappointed?
A family member was home, so why?
Feeling my brain rot further by the second, I forced a smile.
“Noona, you’re home?”
