021. Only This Far
I eventually couldn't hold back and reached out my hand.
...Towards her mouth, not her chest.
"Eup..."
Covering that seductive mouth with my hand, I moved behind her again and lay down.
Then, I turned Yeonju sideways and lay down, pressing my body against her from behind.
...Even just the pressure where my crotch and ass touched drove me crazy, but I still couldn't hold back.
I couldn't just listen, after all.
"...Fuh. Ya..., euk..."
Once I let go of her mouth, my sister, who had been babbling nonsense again, pinched her erect nipples, and only then could she not make idle talk.
...Fuck, I should have done this from the beginning.
"Haak..."
Amid the soft touch of her full breasts, feeling the firmness and the strangely sweet yet oddly slimy scent.
I roamed my sister's body like a horny dog, and with my free hand, I touched everywhere.
The sweaty underboob also,
The slightly folded side also,
The cleavage where putting hand feels heavy weight,
Her lower belly where a lot of fat has stuck.
...All of them were incredibly soft.
...Fuck.
What the hell am I doing, really.
Even while thinking that, I didn't let go of my arm.
Instead, I pressed my body closer and grabbed Yeonju's belly that I was stroking.
...It was incredibly soft.
When she was in high school, she looked like her limbs would break, so skinny.
When did she put on so much fat.
"You gained so much weight. You were fucking skinny before."
"Ha..., isn't it normal if you don't go out of the room?"
"I'm boasting."
"Even if it's me, it should be fine, right...?"
"Does this look fine?"
"Ah, a bit."
While poking and prodding the belly fat, my sister slapped my hand back and rattled off excuses.
...Yeonju from when I knew her as a high schooler wasn't like this, though.
She was much skinnier originally, and I'm not sure if I remember her breasts wrong, but she wasn't this lewd, and she was a diligent girl who was struggling to succeed in piano somehow.
...That kind of person.
"How did you grow up so shamelessly."
...How did you end up like this.
After crawling into oppa's house, she always wears loose clothes that show her cleavage,
Even though it's hot, she always wears dolphin pants,
Like today..., she has a lot without wearing a bra.
I know she gets hot easily, but what is this even with being covered once?
Does she secretly want me to do this?
During the few years I didn't see her face much, what happened that made Yeonju grow up like this.
"Fucking in heat... like this. What the hell."
Yeonju laughed lowly, then suddenly lowered her head a bit.
Then, placing her fingertips on my forearm, she continued speaking as if nothing happened.
"But, I heard a lot when oppa broadcasted what you said."
"What words."
"Saying I gained weight. Saying I look lewd. ...So everyone said it's better?"
The voice that had a hint of laughter a moment ago slightly lowered.
"Usually, the people who always pampered me saying I'm cute. ...When I first started the half-cam, from then on, like oppa, haa. Saying I'm fucking lewd, horny, and fucking molesting from behind. That's what happened..."
Yeonju turned her head.
Our eyes met right in front of her nose.
Earlier, it was clearly eyes playing with me.
Now, strangely calm yet lewd.
I wasn't angry.
Nor was I laughing.
...Eyes lost in a slight thrill.
"Oppa also did it to me like those bastards? Right? A few days ago..., alone in the bathroom. When I was masturbating, you also did it with me...? Ah, ya. Don't pinch..."
"Shut up, fuck..."
...With that gaze saying such words, I felt like I was going crazy.
"Haa..., I, I really didn't know."
"What?"
...That men would get this horny for me.
... .
...Yeonju, who realized she was making men horny, made me angry with every word, so I couldn't stay still.
I wanted to torment this woman a little, to lust and taste her, and make her quiet somehow.
"I, I am naturally..., I am pretty. Piano too... playing elegantly, really..., ha, fuck. Saying such things is embarrassing."
"What's embarrassing?"
...Because I act so cool and high... dignified, men treat me well, and even though they don't know my face, they suddenly confess...?"
Yeonju twisted the corner of her mouth as if it was funny while saying it herself.
"But, not that at all... I thought it was because I look lewd and horny."
...No words came to refute it, so my mouth also twisted.
"Ahahaha..., oppa is the same? ...From the beginning?"
...I couldn't answer immediately.
I had already done too many things to say no.
If I say yes, all the words I've been spouting so far would become lies,
because it was actually a lie.
Wanting to take responsibility,
Wanting her to stay here,
Feeling like I gained value to her.
...Actually, what I wanted was only this.
That hazy face too,
The appearance of playing piano,
All the over 20 years of living as ordinary siblings had no meaning.
It felt like admitting that.
..."No."
I answered after a long time.
"It's not the same."
"Then?"
..."I don't know either, fuck."
"What, that's..."
Instead, I pulled Yeonju in my arms harder.
"Just... right now, you are fucking horny."
... .
..."That's not all."
I didn't know what I was saying after saying that.
But Yeonju didn't laugh.
She blinked her eyes twice in my arms, and only bit her lip slightly.
..."You know that's a worse thing to say?"
"Why."
"If it's just looking at the body, then oppa would think the same as other men."
... .
... .
"But if that's not all―"
... .
..."No. ...I got it."
I closed my mouth without finishing.
Meaning literally, if that's not all.
...What else is left.
Family love?
Pity?
Responsibility?
Guilt?
Or really.
Some other thing that is now disgusting to admit?
With just a few regressions?
I?
...To my own sister?
..."Stop touching my belly."
..."Why."
In the momentarily quiet room, only the sound of the air conditioner running and each other's rough breathing remained.
My hand was still on Yeonju's body.
"The fact that you keep touching me while mocking that I gained weight is more irritating."
"Hate it?"
"Really, am I that horny?"
She didn't answer with words this time either.
"How much― euk..."
...Instead, she mixed her tongue.
Because this side gives a much clearer answer.
"Fuhhaak.... Ah, really..."
After a long time, Yeonju looked at me with heavy breathing.
Looking at my messy sister, my hand that was poking her belly was gradually going downwards.
More,
because I wanted the deeper place.
I, my instinct.
...Kept shouting that I wanted to do it.
..."Are you thinking of doing it up to there?"
Then, the fingertips dug into the pants, and the moment they touched the thigh.
My sister flinched and said in a serious voice.
..."Really?"
Up to there.
I couldn't not know where the line that word meant.
Because I had been worrying about the same thing since just now.
If I regress, I can go back.
I can make tonight disappear.
But it will remain in Yeonju's memory.
Even if hazy like a dream, definitely somewhere.
...And now I know too.
Once you do something, even if time goes back, it doesn't become nonexistent.
Because it's already stacked up to here.
..."Looking at what you're doing."
Eventually, I cowardly pushed the answer.
Yeonju's pupils rolled sideways.
While turning her gaze around and around, she was deeply pondering,
Eventually, she grabbed my wrist that was trying to dig into her.
... .
... .
...I knew she would pull it away.
This time, thinking it meant to really stop, I unconsciously relaxed my fingertips.
Yeonju hesitated for a moment, then turned her head to the opposite side without letting go of my hand.
..."Honestly, it's a bit scary."
... .
..."Today, you can't just stop here...?"
Then... .
..."She put my hand into her underwear."
..."Where is this up to here."
A slightly split voice came out.
It was a question that shouldn't be asked.
I should have just said okay.
Still, my heart was beating as if it would burst.
The fact that Yeonju hadn't completely rejected it, but was trying to set the line.
It sounded like she was allowing up to that line.
..."Oppa, you seem to be really serious more than I thought."
"What."
"Just..., really intensely. It looks like you'll forcibly stop it...?"
Yeonju held my wrist more tightly.
"Honestly, scary."
... .
..."I'll allow touching. Today is... just up to here."
Already the line had been crossed.
From the moment we kissed as siblings.
Or, from the moment I licked my sister's neck, the line had already been crossed far beyond.
...What line was left.
A hollow laugh escaped.
"You said I could do anything."
... .
... .
"Everything is my responsibility, and you did nothing wrong."
Yeonju's body stiffened for a moment.
The sister who had stopped without answering, soon poked my solar plexus with her elbow.
"Ugh."
While I was momentarily stunned, my sister escaped from my arms.
I thought she would run away like that... .
Instead, she turned her body, grabbed my shoulder, and pushed me onto the bed.
..."What, Yeonju?"
..."No matter how much I think."
Yeonju who climbed on top of me looked down at me with a tense face.

"If oppa covers me now, it looks like it'll hurt a lot."
..."Ya."
..."Really, it's scary."
Yeonju didn't run away.
Instead, she pressed her weight firmly to prevent me from getting up easily.
..."Today, just up to here."
... .
..."Because oppa is such an asshole, if I really do it, I won't be able to hold back, and you'll just... do it."
Reciting words that couldn't be denied.
..."I also know I'm an...asshole."
...Muttering words that drive people crazy without care.
..."It really looks like it'll hurt a lot. ...Later."
"Ya―"
While I was swallowing my saliva, my sister spat out words at will and overlapped her lips.
This time, I hadn't approached first either.
While frozen with eyes wide open in surprise, Yeonju grabbed my shoulder tightly and tilted her head deeper.
Whether she was trying to stop me.
Whether she was trying to take the initiative.
Or whether she just wanted to fulfill my request in her own way.
I couldn't tell.
...Only one thing was clear.
Yeonju also chose this moment.
"Heup..., euk.... Fuhhaa..."
My erect nipples touched my chest.
The erect penis finally peeked out over the waistband of the soaked underwear and pants.
The protruding glans touched her soft belly.
...Just that made my head dizzy.
"Uueup..., chuu..."
Mixing tongues, we craved each other's bodies without caring who went first.
My sister pressed me down and groped my face wildly,
I stroked her nape, and with my free hand, I naturally pushed into the dolphin pants and grabbed her ass hard.
As if not caring if breathing stops, craving each other like that.
Rubbing their upper bodies thrown off clothes wildly.
Even though it was clearly felt, rubbing crotch and belly without separating.
..."Eup..."
...I.
Really, without holding back for even 1 minute, I came on the skin touching in this thick kiss.
The semen that had accumulated for over a month, unbearably thick and tingly.
...Like glue in the space where my sister's and my belly touched.
Even after pouring a lot.
"Huaa..., .... ...Chuu..."
Continuously.
Mixing tongues.
How much time had passed.
Yeonju was still on top of me.
I didn't back down either.
While tidying her messy breathing, Yeonju overlapped her lips on mine again.
Not trying to provoke like before.
Not trying to laugh while watching my reaction.
Just.
Like wanting to kiss.
... .
... .
Then, separating for a moment and dripping saliva, we looked at each other.
Looking at my sister's face that was beyond hazy and in heat, I slowly closed my eyelids.
A moment ago, this situation was scary.
Because I didn't know what face to look at my sister if the regression failed.
But now,
Yeonju, who cautiously touched my lips with the tip of her tongue.
Yeonju breathing heavily on top of me.
...Looked seriously lovable.
The moment that thought came to mind.
My heart sank even harder than before.
No.
This isn't because alcohol or excitement has worn off yet.
...I'm going crazy because it's the first time a virgin who hasn't even met a woman in his life has experienced it.
...I had to think that way.
But no matter how much I listed excuses in my head.
I couldn't stop thinking about wanting to let go of Yeonju in my arms.
If I regress, today will disappear.
Even the things I just did.
Even the moment Yeonju kissed me first.
Even the time we couldn't push each other away.
Would all become nonexistent.
Still.
..."Heup..."
...I didn't want to make this night disappear.
A little.
