Yoga
Yoga
I did it.
I've gone and done it.
"..."
On my way out of Kang Yu-na's room.
I stopped by the kitchen, and the hand holding the half-full cup of water was trembling.
That cursed hand of mine still felt the vivid sensation of her warm, soft skin.
And even more vivid than that—
"...She was wet."
A stain that definitely wasn't there when I started this molestation in the name of revenge.
A stain dyed with lewd fluid.
Every time I kneaded Kang Yu-na's buttocks, it spread, clearly revealing the outline of her pussy through her pajamas.
Kang Yu-na hadn't been asleep from the start.
I don't know why she pretended to be asleep.
Just her body flinching every time my hand moved.
And the rough breathing leaking from her face buried in the pillow.
It was at a level where it was impossible not to notice she was awake.
But even knowing that Kang Yu-na was awake, I didn't stop.
Rather... even more boldly.
Unable to resist that shallow curiosity of actually seeing it for the first time—
No, consumed by a desire called sexual lust.
I spread my hands holding her buttocks and stared intently at Kang Yu-na's pussy, almost as if observing it.
The sight of Kang Yu-na's body trembling as the love juice spat out from her private parts soaked through her pajamas and even onto the bed sheets was unbearably erotic.
Kang Yu-na, who didn't stop this crazy act even though she was awake.
And feeling my cock hardening like crazy at that sight, I felt an even more sinister pleasure.
I didn't even know what I might have done if I hadn't left that room by now.
Perhaps now is the last chance to turn things back between me and Kang Yu-na.
The people sitting at the dining table were Kang Ji-eun noona, Kang Seo-ah, and me.
Kang Yu-na's seat was empty.
"...Where is she?"
Before picking up my spoon, I asked Kang Ji-eun.
"She said she's sick and won't be eating today. She said she's resting in her room."
Kang Ji-eun furrowed her brow slightly and wore a worried expression.
"She's a kid who doesn't usually get sick... Did she overdo it because of the big cleaning today?"
Listening to that, I started eating my rice in silence.
Kang Yu-na probably isn't sick.
She might be confused like me, or in the worst case, she might not be eating dinner because she doesn't want to see me.
Kang Ji-eun continued to worry about Kang Yu-na, and a relatively quiet dinner followed without Kang Yu-na.
After the meal, I did the dishes, then moved with heavy steps toward my room.
Then, as I was walking down the hallway and passing in front of Kang Yu-na's door—
Clack—
The door opened, and I ran into Kang Yu-na.
"..."
Disheveled hair.
Pajamas clinging to her as if soaked in sweat.
A flushed face.
And, above all, flowing out as soon as the door opened—
Hot heat, and a thick, sweet, erotic scent.
This appearance was something even I, who doesn't know much about women, could tell was right after masturbating.
The moment I realized that fact, I felt my cock slowly swelling up again.
Whether she knew that or not, Kang Yu-na spoke to me as if nothing was wrong.
"Ah, ahaha— Di, did you eat well?"
As if the earlier incident hadn't happened at all.
I answered while focusing on not letting my 'little brother' get excited.
"Y, yeah. Is... is the sickness okay?"
Despite my painstaking efforts, I could clearly feel my cock, which had started to become half-erect inside my pants, struggling to break through my shorts.
Kang Yu-na widened her eyes as if momentarily flustered, saying "Sick...?", then seemed to realize again—
"Ah, ah! Right, sick. I, I'm fine now!"
She waved her hands and explained exaggeratedly.
Her eyes were spinning, so it was to the point where anyone could tell that being sick was just an excuse.
Then.
Her gaze stopped at my crotch.
"..."
Kang Yu-na's eyes widened slightly.
She had definitely seen the front of my pants bulging.
She stood still as if frozen for a moment, then slowly tried to look up at my face again.
But her gaze kept drifting downwards.
Eventually, unable to take her eyes off completely, she asked in a small, trembling voice.
"...W, what are you doing... tomorrow?"
I wanted to end the conversation quickly and run to my room, but.
I gritted my teeth and answered as calmly as possible.
"Uh... I'm going to school tomorrow."
Kang Yu-na continued the conversation, her gaze still fixed on the front of my pants.
"...I see? And dinner? ...Was it good?"
But somehow, the conversation didn't flow smoothly; it felt like it was being forced.
It was quite suspicious how she kept bringing up random topics for a while without taking her eyes off my pants.
In the end, I had no choice but to come up with an excuse to escape.
"Y, yeah. But I have some assignments to do right now..."
Hearing that excuse, Kang Yu-na fortunately seemed to let me go.
"That's a pity... No! That's not it, u, um, then get some rest!"
She shook her head back and forth as if she'd made another slip of the tongue—
Eventually, with her face bright red, she disappeared toward the bathroom at the end of the hallway, almost as if running away.
Click.
I heard the sound of the bathroom door closing.
Sighing deeply, I also entered my room as if running away and locked the door.
"...Haa."
The inside of my pants was already completely bulging hard.
Kang Yu-na's image filled my head.
The smell of thick, erotic bodily fluids flowing out along with the hot heat.
And the sight I saw when I spread her buttocks.
The pussy spreading open, the transparent love juice stretching like a thread from within, and even her body writhing and spewing out the love juice.
I gritted my teeth.
'No... this is really not okay.'
At the very least, I shouldn't masturbate while thinking about family.
With that one thought, I turned on the computer.
Vrrr—
Even the time it took to hear the boot sound felt like an eternity.
Finally, the monitor screen lit up, and I accessed a site I frequently used and played a random video.
Soon after, obscene scenes began to appear on the screen.
I pulled down my pants and wrapped my hand around my already hardened cock.
"..."
Moving my hand up and down, I tried to focus on the video.
But Kang Yu-na's image kept coming to mind.
The moment my hand spread her buttocks, the sight of the flesh stained with love juice parting with a sound as they separated.
Kang Yu-na's pussy, whose silhouette was indirectly revealed through her thin pajamas.
My hand moved faster and faster.
I could hear the woman's moans in the video, but in my head, Kang Yu-na's rough breathing and the scene of her pussy writhing repeated.
Eventually, the feeling of ejaculation rose.
It was my second ejaculation today, but instead of decreasing, the amount had actually increased.
"...Haa."
Siblings by blood.
At the thought that I had ejaculated while thinking of Kang Yu-na.
A sense of guilt washed over me at the thought that I had broken a taboo in a blood relationship, not just between ordinary men and women.
The next day arrived without incident, and it was evening.
I finished school and returned home.
Click—!
"I'm home."
There would only be Kang Yu-na or Kang Seo-ah at home anyway, but I uttered the formal greeting out of habit.
Since it was dry outside, I tried to pass through the hallway to the kitchen to drink some water first—
On the living room sofa, Kang Yu-na was sitting there wearing some kind of pink yoga outfit.
"Y, you're here?"
She was wearing a sports bra on top, exposing her stomach, and tight leggings on the bottom, an outfit that completely revealed the lines of her thighs and buttocks.
Kang Yu-na smiled slightly as soon as she saw me and said.
"I'm lacking exercise... so I thought I'd try some yoga!"
At that moment, I remembered when I gave her a massage last time.
"—Sh, should I try yoga, hng...♡!"
...She definitely did say that.
Thinking back to that time made me feel strange for no reason.
So I nodded vaguely and was about to head to the kitchen when.
"Do you want to check my form...?"
"..."
I shouldn't look.
The shred of reason I had left was screaming at me not to—
But my body wasn't listening and was approaching the sofa.
"...Yeah. What is it? Are there many?"
Even my mouth betrayed my reason, and I ended up accepting Kang Yu-na's proposal.
'Yeah, it's just yoga.'
Since the situation was already irreversible, I decided to at least rationalize it.
What could happen just by checking her yoga form?
"Y, yeah! The poses are a bit varied..."
As I accepted the proposal, Kang Yu-na, who seemed somehow excited, stood up from the sofa.
And then she immediately started stretching.
With both hands raised above her head, she slowly tilted her upper body from side to side.
The tight leggings completely squeezed her thighs and buttocks, and every time she moved her body, the lines of her muscles were clearly revealed.
...It was just amazing that she had a body without a single ounce of fat, despite being lacking in exercise.
"Uh, well... are you starting over with stretching?"
It was a sight I would have to see soon anyway, but not knowing where to put my eyes, I fiddled with the remote and blurted out something.
But Kang Yu-na stopped moving for a moment and started to look noticeably flustered.
"N, no it's not!"
"...?"
Her face had turned bright red in an instant.
Realizing her own sudden outburst for a moment, Kang Yu-na smiled awkwardly and started to get into position on the yoga mat.
"Ahem! Alright, then... I'll show you this first. I, I studied this today, you know?"
Thus, Kang Yu-na's yoga showcase began.
