Heroine Netori

Waking up, I found Wi Ji-hye on top of me in the cowgirl position, engaging in sex. ...A dream? Or my delusion? No, it was reality. The sensation was undoubtedly the heavenly pleasure I felt yesterday. For her to mount me and sway her hips so freely... I felt a tremendous sense of accomplishment having seduced her in just one night.

I wanted to respond to her enthusiasm, so I gently grasped her soft buttocks and began to thrust with all my might. Naturally, her response was equally fervent.

"Wait, just... Ahh! Don't move... Ahh, ah... stay still!"

But something was off. Wi Ji-hye's reaction wasn't what I expected. Instead of enjoying it, she pushed me away with a look of pity.

"Ahh... Ahh... What, what is this... Ahh!"

Then I felt pain. As if every blood-filled part of me was sliced with a burning knife, the agony was unbearable. I couldn't help screaming out loud, and surprisingly, it seemed I had already screamed several times, as my throat was hoarse.

I felt like I might die at any moment. In fact, dying seemed preferable to this pain. I tried using a healing spell, but for some reason, it didn't work. Purification was the same. It hadn't been this painful when I was having sex with Wi Ji-hye before... Could it be that she was doing something to me?

I lifted my head to look at Wi Ji-hye, and she reassured me with her gaze before starting to sway her hips again. The pain diminished to the level of being pinched by a child.

"It's okay... Ahh, just trust, Ah! Trust me... let yourself go... Ahh!"

My suspicions were right. She had been doing something to me. It was a relief that she was a righteous heroine.

Wi Ji-hye's movements today were incomparably more skillful than yesterday. She had become a genius at making a man feel good overnight. When I felt the pressure of her constricting around me, she placed her hands on my lower abdomen. Her hands, cold as ice, soothingly cooled my heated body. Now, I felt no pain at all.

"Ahh... Ah... Remember the flow of internal energy... Ahh... You understand?"

Internal energy...? What kind of martial art was this? I had confirmed through observation that Wi Ji-hye was just an ordinary civilian. Her words were incomprehensible, but Wi Ji-hye was not one to lie.

However, someone like me, who knew nothing of martial arts, couldn't possibly feel internal energy. All I could feel was how delicious her body was.

"Huuk... Starting, Huu... Here we go!"

Fortunately, I had my observational skills. When I examined my body through observation, indeed, internal energy was flowing as she had said. Amusingly, this internal energy was flowing from her womb through my penis into me.

'So {N•o•v•e•l•i•g•h•t} this warm energy I felt during sex was internal energy...'

That's when I realized the existence of internal energy. It was what had enhanced our sexual experience. Although the internal energy disappeared from sensation once it entered my body, focusing on the parts through which internal energy flowed allowed me to barely feel it.

The internal energy moved complicatedly at Wi Ji-hye's will, circulating through my body. After making a full round, it naturally flowed back to Wi Ji-hye through my penis.

"Ahh... This is the first time..."

'Insane...'

When the internal energy passed through my glans into her cervix, I felt pleasure as if a soft yet firm hand was squeezing me to the root. This was what internal energy sex was about... The reason why sex with Wi Ji-hye felt incomparably better.

"Ha... It's about to pass back, Aah! again... Ah!"

The internal energy that passed to her circulated through the same path in my body as before, and just as she said, it returned to me through her womb.

'Ugh... I almost came...'

Then the same pleasure surged again. It was still an unfamiliar sensation. I could see why Wi Ji-hye quickly became addicted to sex.

Again, the internal energy flowed to me and then back to Wi Ji-hye.

Twice, as I held onto her thighs, Wi Ji-hye embraced me.

Three times, as I caressed her breasts, she gently touched my earlobe.

Once more, the internal energy flowed from Wi Ji-hye to me and I sent it back to her.

Now, even without observation, I could feel and manipulate the internal energy myself.

****

"Slurp, ah... hah, slurp, gulp..."

We kissed naturally, as if we were lovers in love. Although Wi Ji-hye and I had only met yesterday, now we knew each other well enough to caress each other's weak spots.

"Ah... remember this breathing... slurp..."

While kissing me, Wi Ji-hye held my face and spoke about breathing. Then, she pressed her lips against mine and began to breathe erotically. She breathed shallowly, naturally letting out arousing sounds, and breathed heavily with each thrust into her.

"Ah... like this... hah, slurp, ah... gulp, slurp, ah! You understand, right?"

Even though she asked if I understood, I honestly didn't see any difference from just panting. But it was clear there was a meaningful technique to her breathing. There was only one way to learn: practice and repetition. I remembered her breathing sounds and tried to mimic her lascivious breathing.

"Ah... slurp, chup, ah... hah, lick, ah... gulp..."

But at some point, it became indistinguishable from kissing. I enjoyed the kiss, embracing her fully and moving my hips. I swallowed her saliva and thrust powerfully inside her.

"Slurp, ah!"

She stayed close, delighted, and tightened around me, begging me to come. She had forgotten her teachings and focused solely on sex.

"Fill me up! Ah... ah!"

However, thanks to an excellent teacher, I had already learned the breathing technique.

Curiously, as I circulated my internal energy while practicing the breathing technique she taught, a warm energy began to accumulate around my lower abdomen. It was clear that a danjeon, often mentioned in martial arts novels, was forming.

"Ahh! More, let's go!"

In gratitude, I grabbed her waist and thrust deeply to the root. My penis penetrated the entrance of her womb, spraying semen abundantly. She was satisfied and moaned erotically in my ear.

"Ah... now... you'll be fine..."

Despite the end of our sex, I felt no pain. Instead, my body felt invigorated.

Thus, although the sex had ended, it hadn't really ended.

****

Taegeuk Eumyang Body is said to create internal energy in the womb during sex. In short, it makes her an internal energy conduit, but let's not say it's like an onahole. Due to this, Wi Ji-hye's family arranged her engagement with the youngest son of the Namgung family to protect her. The youngest son, truly heroic, treated the anxious Wi Ji-hye kindly, and she fell in love with him, influenced by his character. Perhaps it was a simple infatuation of youth? Surely, she mistook her feelings for love.

But then, someone spread rumors throughout the martial world that she was a Taegeuk Eumyang Body, putting her and the Namgung family in jeopardy. They planned to entrust her to the Ami Sect for protection.

However, the Heukpung Group appeared and kidnapped her. Incidentally, the swordsman who fought their leader that day was an elder from the Namgung family.

"So that's what happened..."

She had learned a martial art called Taegeuk Eumyang Divine Art, which could only be used during sex. She had only learned it in theory but first used it with me during our initial experience. The technique she taught me to save my life was also Taegeuk Eumyang Divine Art, a method to more purely refine the internal energy generated during sex. Without this technique, one can only absorb 60% of the internal energy, but with it, one can absorb up to 100%.

That was the martial art she intended to teach her husband on their wedding night... but I got there first. Thankfully.

"I thought there was a mistake in my observation..."

I had found it odd that a child of the martial arts family appeared as a civilian, but there was a hidden story. Notably, because she is a Taegeuk Eumyang Body, she cannot learn any other internal energy techniques except the Taegeuk Eumyang Divine Art. Men can learn other techniques even if they practice together, an unfair aspect of this world.

Anyway...! Thanks to the Taegeuk Eumyang Divine Art, both she and I have now accumulated internal energy.

And...! We are still actively increasing our internal energy.

"Ah... harder, hot, ah... make me forget anyone else... ah!"

"Maybe... it's time we should head down to the village..."

"Never mind that! Like that! ...Ah... make me forget everything!"

After finishing the treatment and comforting her as she cried, she transformed.
