Chapter 5: Business Trip
My older sister has been home for several days since she returned.
The sister who works as a freelance pianist doesn't know the details of the situation, but it seems like work is constantly overflowing for her.
So, no matter what, I don't mess around with my sister using her piano skills.
Because she's the very driving force that has kept my sister as she is.
"Uwaaa... I'm tired..."
"I'm here?"
My sister places the bag with the sheet music down and naturally approaches me, leaning back against me.
When I insert my arms from below her chest to hug my sister, she completely relaxes her body and leans against me.
Because of that, I have to support the weight of over 50 kilograms for a height of 161 cm all by myself.
It's just like that, and I don't hate it.
Since the moment I surpassed my sister's height, I've been playing around with her.
Each time, I could naturally have skinship with my sister.
At times like this, no matter where my body touches, my sister doesn't show any dissatisfaction.
"What do you want to eat?"
"Jjigae."
"Doenjang?"
"Kimchi, of course."
"Mom always makes kimchi jjigae."
"Of course. I asked you to make it."
"Try some other things too, pig. Stop being picky."
"So I made it with pork kimchi jjigae."
"Haa... you really want to die."
I prefer kimchi over doenjang.
Unlike kimchi jjigae which tastes good with just kimchi and tofu, doenjang jjigae has too many vegetables that I don't like.
If I remove those vegetables, I won't get the desired taste, so I have no choice but to like kimchi jjigae.
"I don't eat the tofu."
"No? Now I can eat it?"
"Oh, really? After doing some social life, I guess you can eat it."
"Of course."
"How many?"
"...One?"
"Do you want to die?"
Who looks at who and says picky eater.
After eating the kimchi jjigae together, I entered my room.
My sister naturally followed me in and climbed onto my bed, lying face down and starting to look at the tablet.
It's a shame she's not wearing a short miniskirt.
"Why all the commotion here."
"I don't want to go to the bedroom."
"..."
Since my sister moved out, her room has become a storage room, and the living room has nothing to do.
The only TV is in the bedroom, and in that room, my father's portrait is hung very well.
That's why she doesn't want to go there.
I also don't want to go to the bedroom unless it's necessary.
That's why my sister has been able to endure until now.
By completely erasing memories of my father from her mind.
By turning her into a stranger.
The death of another person isn't that sad.
"Tsk... why isn't that jungle idiot blocking the tower?"
I'm playing a game, and if my sister needs to listen to songs she has to practice or watch a drama, she listens to the song.
Originally, I wore headphones all day, but because my sister kept talking to me, I put one side behind my ear and play games.
"When is mom coming?"
"I don't know. She'll come soon."
It's past 10 o'clock.
Mom usually returns home between 10 and 10:30.
When she comes home, she immediately showers, goes into the bedroom, watches TV or videos, and falls asleep.
'It's been a while since we didn't talk much...'
When dad was alive, we talked over small things, so it was noisy.
What I hated then, now looking back, it's so nostalgic.
The words "do well when you're there" were like that.
"A call came from mom."
"Sister, answer it."
"Yeah. Hello?"
There's nothing hidden from my sister.
Not only my sister, but I easily hand my phone to others.
My phone is fine like that.
I watch adult videos as streaming.
"Mom. Me. Yeah. Together. Yeah~ Okay~"
"What?"
"Mom is going on a business trip to the province and will come back tomorrow."
"Tomorrow...?"
"Yeah."
Wait, then tonight...
Does that mean there's only me and my sister at home?
♠
"Move a bit to the side."
"This is as close as it gets."
My bed is single size, so it's narrow.
If we try, we can fit, but the effort is quite uncomfortable.
I can't fully stretch my shoulders, and I have to sleep sideways.
Because of my waist, it's even more uncomfortable to lie straight.
Of course, it's uncomfortable, but I don't hate it.
"Why do you keep wanting to sleep together?"
"The floor in the living room is cold."
"I can turn on the heater."
"That one is in the bedroom."
"I'll turn it on?"
"No need. I'm already lying down."
"..."
I originally wanted to sleep together in my room, but mom said not to bother my sister because the bed is narrow, so my sister sleeps on the living room floor.
From my sister's perspective, it's finally a day when we can sleep together.
"Look this way."
"Why."
"Because of my butt, it's pushing me."
"Annoying..."
When I turned my body with a rustling sound, I met eyes with my sister looking up at me with her round eyes.
It's a simple situation, but I end up breathing carefully.
I brushed my teeth, but worried about bad breath reaching my sister.
"Why are you squatting like that? Stretch out."
"That's why it's warm."
"Anyway, I'm going to cover with the blanket, what."
"Don't cover. It's hot."
"What are you saying. The floor is cold."
"Right now is perfect."
We share some trivial small talk and fall asleep.
─Don't put your hand there...!
Because I had a lewd dream and woke up, my sister's face was right in front of my nose, as if she had climbed up while I was dreaming.
'No bra, huh.'
I couldn't see it before because I turned off the light when playing games, but she is wearing no bra.
Perhaps because the weather is warmer, some sweat droplets are visible between the V-neck of the shirt my sister is wearing.
The boundary line created by two breasts overlapping.
The depth of the valley proving it's not exaggeration.
In the pitch-black dark room, the desire lump that starts to become clearer as the vision adapts.
Blood starts to rush to my groin just by looking at it.
'Shit...'
The tent made quickly becomes full size and pokes at my sister's lower abdomen.
"...!"
As if responding to my inner wish, my sister starts rolling towards me, and naturally her lower abdomen touches the end.
My sister stops, blocked by something unknown from her perspective.
However, the touching posture remains the same, and rather, my penis starts pressing against her lower abdomen.
Does my sister know that she is being pricked by her little brother's penis right now?
Actually, my sister might have interest in my body or something.
I also have a lot of interest in my sister's body, so I think it's possible.
"...Sister."
"..."
I called out to my sister with 99% air voice, but no reaction.
Normally, the alarm rings, and even if I wake her up several times, she doesn't get up, so there's no way she's waking up now.
'She's really sleeping well...'
The more I get here, the more greedy I become.
What is in front of me is my sister in a defenseless state, tormenting my penis.
And that sister has no owner right now.
Even if my sister finds out, she won't get hit by that owner.
'No, this shouldn't happen in the first place...'
Up until two years ago when my sister moved out, she only liked it, but she didn't look this sexual.
Moreover, oppa Ji-young is a good person, so I thought about handing it over with the thought 'Yeah... if it's oppa.'
But when I actually broke up, I started to feel a sense of accomplishment that I could fill that void.
The man next to my sister now is the only one I have.
"Kuu..."
I pretend to be half-asleep, and carefully place my hand on my sister's forearm.
Just by placing it, I feel a huge tremor from me.
Is it okay to continue from here? What if I'm caught? Such anxious thoughts are resolved when my sister places her hand on my arm and presses it.
The hand that falls downward with mass added to mass.
That hand naturally heads towards my sister's chest.
'Is it sleeping...?'
It falls exactly, and exactly one breast is caught in my palm.
Although one cloth is covering it, since it's no bra, I can properly feel the sensation of touching the breast.
This is what a woman's breast feels like.
The penis poking at the lower abdomen twitches and rubs, making it painfully hard to burst.
My waist is also moving and causing a fuss.
If I accidentally twitch here, what happens──
"Uung..."
As expected, feeling the weight, my sister frowns and waves her arms around as if to swat a mosquito, hitting my arm.
When I put the lost arm on my thigh, I feel a huge sweat.
The immense fear and the pleasure returning from that fear.
It was like walking a tightrope, like fighting with a North Korean soldier at the DMZ by spitting.
I can understand why people fall into the abyss of gambling.
Once you taste it, you want to taste it again and go crazy.
"Careful..."
"Huh?!"
When I was waving my arm earlier, my sister's body was facing outward.
Because the direction of sleep changed, when rolling, I hugged her trying to roll outward.
My sister, startled, opened her eyes.
"Huh? What's wrong?"
"No... I almost fell."
"Really? Thank you..."
"..."
"..."
After saving my sister from danger for a moment, a greater crisis came to me.
My still not subsided penis started poking at my sister's butt this time.
Moreover, because I hugged her tightly, it feels properly.
My sister also noticed it, so she didn't move from there.
Of course, not noticing is strange. It's hot and hard touching her butt right now.
Surprisingly, my sister confronted this situation directly.
"Why are you standing?"
"...I woke up from sleeping."
"What is that..."
"No, it's real."
It's not real, but logically it is.
Even if I think about it, it's a genius excuse.
"Make it go down a bit."
"Wait. It'll go down soon."
My sister, who calmly got up, looked back at me and lay down again.
Fortunately, the atmosphere wasn't different from usual.
But the subtly closer distance, and my sister's gaze directed downward instead of my eyes, clearly signaled that something had changed.
