6. First Yin-Yang Unity (1)
So-ye’s coming-of-age ceremony had been surprisingly simple.
“Hehe…”
It was almost as if she didn’t need to linger, since there was a long night ahead of them. Even the minimal coming-of-age had felt abbreviated.
Of course, that didn’t mean So-ye’s outfit was anything less than perfect. It was so alluring that anyone who might have been a suitable match for her would have been unable to resist the urge to devour her whole the moment the ceremony ended.
A strikingly unique black garment, yet one that highlighted every one of So-ye’s seductive features. If even the slightest mark were left on her body, it would have been impossible to hide the fact that she belonged to me.
“…”
And the more I gazed at such a radiant So-ye, the more tangled my feelings became.
Was I truly worthy of spending a lifetime entwined with a sister who looked so bright and pure?
Or would I only become another burden on her free, soaring life?
“By this… the age of adulthood… has passed…”
After that, I remembered little.
So-ye’s appearance had made my head ache, so I had simply waited for time to pass.
“Ucha… Oppa! The coming-of-age ceremony is over! Hehe!”
How swiftly the moments had flown.
Only moments ago it had still felt as though the ceremony was in full swing.
“Then…”
“Then… I’ve already passed the age of adulthood, so are you going to do it with me?”
Guilt slid through me like oil on water.
With the knowledge that I had crossed the heavenly law and must now explore my own sister’s body…
I wondered if it was right for me to ever stain this innocent, laughing So-ye with my own color.
“Yes…”
“Eh! Even in the marketplace you said older brother should smile more…”
Yes.
I needed to smile.
“Sorry. I had a bad thought for a moment.”
I could no longer hide behind age, and this was a fate I had to fulfill someday.
So today, for the first time, I crossed the heavenly law.
To save myself…
And to save my little sister.
***
Memories from a long time ago… or rather, a night whose exact date I could no longer recall, when I had spoken with Dang So-so, began to surface.
“Even with that face, you’re still a virgin?”
“…Is my face that serious?”
Probably… the memory of sharing a drink with Dang So-so to wash away the fatigue of solving various incidents while traveling with my sister and completing Murim Alliance missions.
“No, honestly, even if I look like a dog I still feel attractive… Uup! So I think my face is attractive too, but it’s funny that at my age I’m still a virgin.”
There had been suitors, but I had rejected them all.
“No… Why? Even the proposal from the daughter of a great family?”
Why reject the proposal from the great family?
Of course…
“Because someday my body that will be used… must not be dirtied by anyone.”
Since I had to overlap bodies with So-ye someday…
Of course I had to keep a pure body and mind untouched by anyone.
I would not accept proposals lightly.
Moreover, a proposal without love was an act of disrespect to the other person, wasn’t it?
“Uek… Honestly, even if I can’t read fortunes well, I can swear to this.”
“What?”
“Ja-hyeok oppa will never have a normal first experience.”
Hmm… I thought even dual cultivation with my sister would already be far from normal.
What would truly be a non-normal first experience…
With that thought, memories of the past faded away.
***
The room of mother and father.
In a room with excellent soundproofing, only So-ye and I remained.
“So-ye! Do as Mother taught you!”
After Mother’s instruction to So-ye had passed, an awkward silence filled the room.
“…”
“…”
Originally, since neither of us had ever performed yin-yang unity… meaning we had never done dual cultivation before, it was ambiguous who would lead the relationship anyway…
In that situation, So-ye spoke first.
“F-first, let’s kiss…”
The first kiss, starting with a response just like So-ye.
“Then…”
Our tongues tangled and pulled at each other, mixing our brains into a chaotic mess…
More than anything, the taste of the hawthorn Tanghulu I had eaten in the marketplace lingered.
“Sweeter…”
With a tongue that seemed sweet and melting, our mouths met, and because air was lacking, breathing became difficult.
Yet there was no reason to end the kiss, so we continued to explore each other until consciousness was about to cut off…
Hug—!
“Hueek…”
“Haa…”
After barely pulling our mouths apart, the sound of intense closeness echoed in the space without knowing how tightly we were pressed.
And because So-ye knew that if we kissed we would have to proceed with the following event, she immediately began removing her clothes.
“I’ll take off the clothes I was wearing first.”
-Sruruk…
Soon, the thin fabric that had been wrapping So-ye came undone…
After throwing them off from top to bottom, her budding peaks began to rise proudly.
“Uuu… This is embarrassing, oppa.”
Honestly, even I didn’t feel no desire toward anyone.
I could release normal lust, but because I was so full of vigor that I had to forcibly hold back the overflowing desire…
“Gueuk… I didn’t know it would be this big down there…”
The moment I saw So-ye’s naked body, my manhood twitched as if bursting out of my clothes, and transparent precum flowed with a gulp.
-Sruruk…
Soon, So-ye lowered the pants I was wearing directly, and the large manhood that had been trapped by the fabric came out and struck So-ye’s thigh.
Slap—!
“Uee…?”
“S-sorry, So-ye…”
So-ye had been momentarily flustered, but soon regained her senses and…
“Chuup…♡”
She kissed the tip of the manhood, the glans, and fiercely kissed as if preparing for what would happen afterward, like a pre-preparation.
“Uuek…”
The feeling inside the brain was like burning from yang energy.
It felt like I hadn’t experienced such strong stimulation before…
But thinking about it, until now I had consumed yang energy through martial arts, yet the essence left in my body had remained completely unconsumed, compressing and clumping together.
“Uup…♡”
Then So-ye took the manhood into her mouth and began shaking her face back and forth, and the stimulation from So-ye’s mouth focused on the manhood made it seem like it would burst.
“So-ye…!”
Suddenly, a feeling of blood not flowing to the head came.
Breathing became difficult, and at the same time, blood rushed below, feeling like the dam that had been holding it back would break right there.
“Stop…!”
If I released like this, I knew the essence I had kept for so long would all spill into So-ye’s mouth, so I tried to stop her, but…
“No…♡”
Unfortunately, So-ye, perhaps stimulated by some masochistic feeling from oppa’s appearance, grabbed me and refused to let go of my mouth, increasing the speed.
Gurgle—!
Soon, the manhood could no longer endure the stimulation and began to ejaculate freshly…
-Ulculcul…
The white turbid liquid began entering So-ye’s mouth all at once.
Since I hadn’t consumed any at all, there was a lot of it and thick, so even if I didn’t swallow it…
“Beee…”
So-ye didn’t spill the turbid liquid and swallowed it all into her mouth…
Like wanting praise from herself, she left the turbid liquid in her mouth and opened her mouth to show a smile.
“Well done, So-ye…”
“Gamsahae…”
When I praised such So-ye, she smiled as if she had done well and began chewing the turbid liquid in her mouth with her teeth.
Honestly, she had wanted to swallow it straight to her throat, but…
Surprisingly, the viscosity of the turbid liquid was too strong, so she forcibly chewed and ground the precious turbid liquid given by oppa and eventually started swallowing it to her throat.
“It’s thick… Because it’s sticky, it’s not easy to swallow to the throat.”
It looked like it was clumped like condensed milk, but the taste was overly thick.
And because it was sticky, if not chewed in the mouth, it stuck to the throat, and the smell was quite foul.
But the more I thought about oppa, the feeling that the thing So-ye had swallowed had value and had become one body with oppa…
“Tasty…♡”
No matter how sweet and rich the tastes So-ye had felt so far, or even if I ate all the delicacies of the central plains, I could never compare to this first taste.
“Then oppa… now we have to do it for real.”
And now, finally, the turbid liquid blocking oppa’s manhood had been released…
So-ye lay down with her body and prepared to accept oppa.
The first yin-yang unity…
