022. Up to Here
The lips didn't part easily.
The urge to devour each other, whether we suffocated or not, had vanished by then, but neither of us wanted to be the first to pull away.
With our eyes half-lidded, we pressed our lips together again every time they parted.
"...Eup."
Once.
"Ha. ...Chuu...."
Twice.
...Three times,
four,
five.
Surely, we did it at least ten times.
Eventually, the time we spent looking at each other grew longer than the time our lips remained pressed together,
and the excitement that had burned my thoughts white began to subside little by little.
"...."
Gradually, reality returned.
My younger sister, straddling me and breathing hard.
Me, unable to let go of her waist or hips.
And,
even what we had just done.
"...Ha."
Yeonju lifted her head first.
She roughly brushed back the sweat-soaked bangs clinging to her forehead with the back of her hand, then started to rise as if she was finally going to get off me.
"Uwat...."
But when she tried to peel our bodies apart, countless strands stretched between Yeonju and me, long and stringy like melted cheese.
...My semen was still so thick that it hadn't even begun to run like water, and had instead glued us together.
The sight looked pretty damn filthy, depending on how you looked at it. Horrified, Yeonju clung right back to me instead of pulling away, making a thoroughly appalled face.
"...Feels like the bed's going to get fucking filthy if I stand up, oppa."
"Hold still a second."
To prevent such a catastrophe, I hugged my sister, who was folded over me, and awkwardly eased my legs off the bed first.
With one hand around my sister, I planted the soles of my feet on the floor,
then used my free hand to support myself against the ground,
and crawled backward like an upside-down spider, barely managing it.
"Ah, fuck. She's fucking heavy...."
"...Says the guy who's weak."
We somehow managed to roll off onto the floor together. Only after getting down did we separate from each other and freak out at the traces smeared across our stomachs.
"Ah, seriously...."
Yeonju finally got her feet on the floor and looked back at the bed with a short groan.
...Still, some of it did get on there.
It could be washed anyway,
though I'd be going back in time before I got around to doing the laundry.
"You got it on the bed after all."
"Can buy a new one."
"Showing off how rich you are?"
"Isn't this what money's for?"
"Ha."
Yeonju laughed at my shameless answer as if she couldn't believe me, then looked down at her own body again.
Only then did I come to my senses and open the drawer beneath the bed.
Tissues and wet wipes, kept where they were easy to reach.
I picked up the things I would normally have grabbed without a second thought, one in each hand, and handed them to Yeonju.
"Here. Wipe yourself down."
"......."
Even after taking the wet wipes, Yeonju didn't use one immediately.
Instead, she glanced back and forth between the drawer and my face with a strangely suspicious look.
"...What."
"...."
"...Since this used to be my room, of course I know where the tissues are. Why are you looking at me like I'm suspicious?"
"Hmm."
Yeonju pulled out a wet wipe and snickered.
"I didn't even say anything, so why are you getting guilty and making excuses all by yourself?"
"...."
"...What did you normally do under here?"
"...Blow my nose, I guess. Why?"
"Oh, is that so? ...Under the bed, to blow your nose. Mmm-hmm."
...Seriously.
I can't win with her.
Whether I explain myself or not, I lose.
"...At this point, I think I can tell what you're about to say just by looking at you."
"Really?"
"Your eyes usually give you away."
I looked at my younger sister, whose schemes were now written all over her face, even in her eyes and the corners of her mouth. Yeonju roughly wiped off the stuff on her stomach and crawled toward me.
Then she suddenly thrust her face right up to mine, grabbed my shoulders, and looked down at me.
"...Then what do you think I'm thinking right now?"
"...."
Her eyes curved into thin slits.
Her cheeks were faintly flushed, perhaps from the heat that hadn't fully faded yet.
Her lips were still wet and glistening from all the saliva we had mixed together moments ago.
...What could she want?
I thought I knew now.
"Eup...."
...What else could it be besides a kiss?
We hadn't done anything more yet.
"Heh..., heup...."
I wrapped my arms around Yeonju's waist and kissed her again.
Naturally, Yeonju didn't push me away this time either.
As if grading my answer, she wrapped her arms around my neck and slowly returned the kiss.
The tips of our tongues tangled briefly.
Our breathing grew ragged again.
...So it was the right answer after all.
"Whoo...."
When I pulled my lips away, Yeonju gazed up at me hazily, then laughed softly.
"Haa. ...Wrong answer."
"What?"
"Completely wrong, oppa."
She drew an X with her finger and teased me, insisting that I had gotten it completely wrong.
...For someone saying that, didn't you enjoy it a little too much, Yeonju?
"It looked like you were saying I got it right."
"Not everything that's true is the right answer, you know?"
This shameless younger sister calmly pushed my chest with the same index finger she had just used to draw an X.
...Yeah, not everything that's true is the right answer.
"What I really wanted was to wash up."
"...How was I supposed to know that?"
"You said you could tell just by looking."
"So you want to shower together?"
"Hmm."
Yeonju's mouth curled upward as she answered coyly while stretching.
"...Then how about we go shower together, Yeonju?"
...But you wanted me to be the one to say it first, didn't you?
Ha, fuck. How did Yeonju end up like this?
After being on camera for years, she seemed to have gained so much experience seducing people that I couldn't help but wonder―
"I said I wanted to wash up, oppa. I never said I wanted to shower with you."
As soon as I had that thought, Yeonju snickered and shoved my chest away.
Then, without giving me a chance to grab her, she scampered off to the bathroom, tododo.
...Of course, I didn't hear either the bedroom door or the bathroom door close.
Whether she had done it on purpose,
or had simply forgotten because she was too flustered.
Either way.
"Ha."
A hollow laugh escaped me.
"...I really can't win with her."
...I was seriously starting to feel like Yeonju was wearing me down.
***
When I entered the open bathroom, the sound of warm water falling reached me first.
"Hey, Yeonju."
"What?"
Because she had gone inside the shower booth, I couldn't see her clearly through the opaque door, but her silhouette stood out all the same.
...She got naked.
Well, if you're going to wash, you have to take your clothes off. The bottoms too.
"Why are you coming in, you lunatic?"
"You didn't close the door."
"Just because I didn't close the door, you barge in while your sister's showering?"
"You said we should shower together."
"I said I didn't want to!"
Even as I took off my pants and stripped naked myself, Yeonju didn't immediately come out to push me away or chase me outside.
She only kept snapping at me.
To teach this noisy younger sister a lesson, I strode toward the shower booth and roughly opened the closed door.

...It was probably the first time in my life I had seen my younger sister naked since puberty.
No words came to mind to describe it.
Except sexy.
"...You really came in after all, Yeonwoo."
She probably hadn't exercised a day in her life, so why wasn't her butt sagging at all?
She had a subtle bit of belly fat, so why were her arms and legs so slim?
Her upper arms were thin, so how were her breasts that big?
...Why.
Why did every part of her look exactly like the kind of porn I searched for, Yeonju?
"Pervert."
"What?"
"You barge in while someone else is washing and stare at me like that."
"I'm not a stranger."
"Then is it okay to peep while your younger sister is washing?"
"I wasn't peeping. I came in right out in the open."
"Wow, you're seriously shameless."
Yeonju giggled, covering her chest with one arm.
Even so, unlike before, she couldn't quite meet my eyes.
Had she gotten shy now that we were facing each other in the bright bathroom, even though we had pressed our bodies together like that moments ago?
...I was a little embarrassed too.
"Oppa, you weren't like this back then too, were you?"
"What?"
"You knew because you used to spy on me while I was washing."
"...I told you I didn't."
"You said you remembered what I looked like."
"That's―"
"Fucking pervert."
Yeonju had been chattering away excitedly again, but she abruptly shut up when I approached without answering.
"...."
Her gaze dipped down for an instant. After catching sight of it, she slowly backed toward the wall.
...She had toyed with me like that in bed.
Until I came in, she had been trying to tease me with that sly smile.
But now, under the bright lights, she couldn't even meet my eyes properly.
The sight was so cute that I laughed.
"Why'd you get quiet?"
"...You're noisy."
"Go on, call me a pervert again."
"Just wash yourself."
Now slightly demure, Yeonju worked up a thick layer of lather on a washcloth, then roughly rubbed the suds over her body.
After that, she silently held out the still-lathered washcloth toward me.
"...What?"
"Use it."
"Weren't you going to wash me?"
"Take it and quit talking shit."
I took it and rubbed a rough layer of lather over my torso and arms as well.
...After that, naturally.
"...."
I started soaping my sister's back too.
Her back and shoulders were soft and yielding overall, but felt relatively firm compared to the front.
After thoroughly lathering every inch, I lowered my hand and gave her already-sudsy butt a hard squeeze.
"...I already washed there. Pervert."
"I know."
"Then why are you touching it?"
"Just checking."
"Checking what, you perverted bastard?"
I felt like I could get addicted to this soft, yielding sensation.
Even while I obsessively scrubbed her butt, Yeonju cursed me, but she didn't try to remove my hand.
...I'm seriously about to lose it.
Honestly, I couldn't take it anymore.
Just touching her like this wasn't enough.
"Hey, fuck...."
I pressed my body against Yeonju's back and wrapped my arms around her.
Naturally, there were no more ragged pieces of cloth in the way, so our bodies pressed even closer together.
My already-lathered skin and her buttocks were pressed so tightly together that it felt as if we had become one.
...Fuck.
I had already ejaculated just from rubbing against her belly fat a little.
If I came again like this, wouldn't she tease me like crazy?
"You don't find these heavy?"
To distract myself somehow, I hugged Yeonju and supported her heavy breasts as I changed the subject.
...I honestly didn't have the confidence to endure it if she started teasing me like this.
It was better for me to make the first move.
Besides, the one taking the lead had an easier time controlling things.
"What?"
"They look incredibly heavy. Doesn't your back hurt?"
"...Of course it hurts."
"Then exercise."
"You exercise first."
"I'm not as soft and flabby as you."
"You were whining about how fucking heavy I was a minute ago."
I had nothing to say to that.
...Still, I had to keep up this pointless conversation to shut Yeonju's mouth.
If I left her alone, she would start spouting something weird again.
To keep her from pulling any more nonsense, I hugged Yeonju even tighter in my arms.
Although Yeonju sighed, she remained still, leaning against me.
As I silently soaped her breasts, I discovered another strange thing.
"...Why did they turn out like this again?"
"...Why are you asking me about something that's always been this way?"
...The brief break had made her nipples hide again.
Ha, fuck.
Did that mean she had been aroused the entire time earlier?
"I'm not accusing you. ...I just thought it was cute."
"...Shut up."
That fact was even more erotic than the shape of her nipples, so I rubbed my index finger vigorously and tried to arouse my sister once more.
Each time, Yeonju squirmed all over as if ticklish and let out shallow breaths, but, true to form, her nipples reacted honestly to my touch and began peeking out from inside her areolas again.
"...Oppa, you're fucking persistent."
"I have to wash here thoroughly too."
"I wash them properly every day even if you don't tell me, you know?"
...Every time I heard this embarrassed voice, I felt like my brain was melting.
This clearly wasn't what I had wanted, nor was it the kind of relationship we were supposed to have.
I had only... wanted to go back one day.
My sole purpose had been money, purely and simply.
...Why, after already achieving more than enough to say I had met my conditions, was I still doing this instead of simply passing the hell out?
"...Oppa."
"What?"
"Earlier. ...Were you really that fucking turned on?"
...Why did my dick react every time she spoke with even a hint of playfulness?
She was definitely the Yeonju I knew.
As children, we had been awkwardly distant, barely acknowledging each other; since middle school, she had always been rude as hell; and as adults, I hadn't even seen my own sister's face all that often.
"...You got so horny you couldn't think straight just because we brushed against each other?"
"...I haven't done anything in over a month."
"Even so. ...You were built up enough to cum that much?"
"...What would someone who's never done it know?"
...Why was she so fucking arousing?
Even if I hadn't masturbated in nearly a month,
was I really so aroused that a little rubbing alone made me ejaculate so insanely?
"I'm twenty-six. ...I watch sexy stuff, and I know all there is to know."
"Watching it and doing it are the same?"
"Even without experience, you can roughly tell how much... how much there is just by looking, can't you? What... You left it like something out of a manga. ...Isn't it weird to think I wouldn't notice?"
"...Yeah, I was fucking horny. So what?"
"Puh-heup. ...You should've admitted it sooner."
...Whose spell had I fallen under,
that every single thing Yeonju did was so damn arousing I couldn't stand it?
"Hey."
"What―Uht...."
As my hand slowly moved lower, Yeonju's words trailed off.
The sound of water hitting the bathroom floor suddenly grew louder.
"Why are you acting so damn cocky toward your oppa?"
"...Can't I?"
"...."
Why was I so desperate for her?
The answer was probably because she kept trying to get one over on me.
Just because she had gotten some leverage, she dared to act that way despite being my younger sister.
She was trying to climb on top of me.
I had been kind enough to comfort and soothe her.
"...Eut...."
When I pushed my hand a little farther down, Yeonju turned her head slightly.
I could barely see her reddened ear and profile.
"...Since you started acting cocky, I get to do it too?"
"...."
When I said it in a low voice, my sister didn't laugh this time.
"...If you don't like it, say so."
Instead,
she placed her hand over my wrist.
"...Only this far."
"...."
"For today, only this much... ...You can use me."
...Then,
she gave the tiniest nod.
Backing her body away slightly,
until she bumped against my pubic bone.
