Extreme Techniques

"Hold on. Scattered Thunder is a technique I only just created, so I need a moment to prepare."

She fetched her sword and settled into stance before me — knees bent slightly, feet set. Closing her eyes, she focused quietly on her breathing. Static crackled across Jin Seyeong's body, and a faint wind began to stir.

A silent minute passed. Then her blade carved the air in every direction. The tip never touched me, yet the sword energy rode the wind and spread outward on all sides.

Crackling blue current erupted from the sword energy and seized the space around us.

I felt a stifling pressure settle over everything.

My mana… it's completely scrambled. I can force it to move if I try, but it's exhausting. Feels like I need five times the concentration I normally would.

The current saturating the air was scattering my mana. Five seconds later, the electricity faded and the mana flow returned to normal.

"…This is similar to Sealing Thunder, isn't it?"

"I knew you'd catch that right away. You're right. Scattered Thunder is a technique I built with Sealing Thunder as the foundation. I added the power of wind to spread it in every direction. Father recognized it as an Extreme Technique, but… I still consider it incomplete. The ultimate purpose of Scattered Thunder, the way I envision it, is total spatial dominance."

In other words, she had used wind to diffuse Sealing Thunder across an entire area.

"That's incredible."

My admiration was genuine. Loading lightning onto wind and dispersing it — and not ordinary lightning, either. I couldn't even begin to guess how many failures she'd endured to get this far.

"But this is an Extreme Technique only you can use, right?"

Jin Seyeong's ability was wind manipulation. The technique worked precisely because that power had been woven into it so cleanly.

"Not necessarily. Anyone can generate ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠a bit of wind with a little effort. With a bit more practice, you'll be able to do it too."

"Not as easily as you, though."

Jin Seyeong scratched her cheek and laughed.

After that, she walked me through the concrete methods for using Extreme Techniques. Of course, learning the theory didn't mean I could use them immediately — that would take dedicated practice of its own. I set the Yeongcheon Style Extreme Technique training aside for later, looked at Jin Seyeong, and raised Hwaryeonbido.

"Noona. We haven't seen each other in ages — shouldn't we spar?"

"Sure. I'm looking forward to seeing how much you've grown."

Jin Seyeong grinned with open combativeness and lifted her sword.

"Wait!"

"Hm?"

"Noona. Have you forgotten how we spar? Let's ditch the clothes. They're just in the way."

"W-we don't have to do that. It's been so long, I'm embarrassed…. Can't we just spar like this?"

"We do it the usual way. The usual way."

Moments like this called for confidence. I stripped off my clothes and tossed them aside until I was completely bare — underwear included.

Jin Seyeong glanced at my body, sighed, and undressed. It was exactly the body I remembered. As I stared steadily at her chest, I watched her pink nipples harden.

"Ready?"

"You first? Or me?"

"Whatever you prefer."

"I'll go first."

I leveled the tip of my blade at her and stirred my mana. It rose from my dantian and flooded through my entire body. The moment my center of gravity pitched forward and my body felt deceptively light, I kicked off the floor and launched. Thunder cracked with every step of my footwork.

Yeongcheon Style — Flying Tiger.

Surprise flickered across her face as she responded. Her sword moved with fluid grace and caught my blade. The instant the steel crossed, a fierce wind erupted. My body couldn't absorb the impact — I was driven back. No. I was sent flying.

I barely managed to regain my balance and land, then tugged the corner of my mouth upward.

"You know this is the first time you've ever used wind manipulation in a spar with me?"

"I didn't have a choice. If I'd taken that strike head-on… it would have put real strain on my body. Your attack was that ferocious."

"I'm not complaining. Knowing I pulled that much power out of you actually feels pretty good."

Still not enough, though.

Judging by how composed she still looked, I hadn't forced her to go all out yet.

Acceleration.

I ramped up my speed and closed the distance to Jin Seyeong.

Charna.

Yeongcheon Style — Lightning Flash.

I unleashed the fastest strike I had. Hwaryeonbido's edge painted a trail of red lightning through the air, aimed at Jin Seyeong's shoulder. She didn't flinch. Calmly raising her sword, she met the attack. For a split second her blade seemed to stretch and snare mine — and then my sword was already ricocheting away.

She adapted Thunder Snake into a counter? So that's another way to apply it.

The surprise lasted only a moment. I locked my focus on the blade and pressed the assault. Lightning-charged steel tore toward her with savage intent. Jin Seyeong's feet began to give ground, step by step.

I'm overwhelming Jin Seyeong…!

In the dozens — hundreds — of spars we'd had, this had never happened before.

This is how far I've come!

Exhilaration flooded through me and my body burned hot. The force pouring into Hwaryeonbido intensified, and the blade's speed climbed higher still.

"Yujin. The thing you have to watch for most in combat is excitement. When you get worked up, your field of vision narrows."

Her advice landed at the same moment I finally noticed. Wind filled the space around me. At some point I had been completely surrounded. Those currents weren't dissipating — they were holding position, ready to shred me the instant she willed it.

If this had been a real fight…

I would have ignored the wind, triggered Heavenly Mind and Thunderbolt, and charged in ready to die.

Pointless fantasy. This was a spar from the start.

I lowered my sword. The red lightning wreathing the blade guttered out and vanished.

"I lose, Noona."

"Mm. That ended a little anticlimactically. Want to go again?"

"Not a bad idea, but I don't think I could hold back properly. Let's spar again later. For now…."

I deliberately put on a wicked smile and looked at ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠her. The residual wind in the room was still working on her C-cup breasts, making them sway.

My cock was already hard, asserting its presence before I could do anything about it.

"Ugh… y-you're the same as ever."

Jin Seyeong tried to sound nonchalant. The flush on her cheeks told a completely different story. Her gaze kept drifting, not so subtly, toward my cock.

"Noona. Don't dismiss the wind — keep it going."

"Huh? Why?"

"Your tits bouncing in the wind and that bush of yours fluttering around… it's so fucking hot I can barely stand it."

"You little pervert…!"

I strode right up to her and shoved my right hand between her thighs. Smooth pubic hair and a slick pussy met my fingers. The moment I drove my middle finger deep inside her, Jin Seyeong pitched forward. Her hands clamped onto my shoulders, and her lips parted into something lewd and hungry.

"Last time I saw you, you were bare down here, weren't you?"

"How long ago was that…. Did you prefer it shaved? I haven't had time to take care of it lately…."

"Either way works for me. Your pussy is still your pussy."

"…Why do you say embarrassing things like that without the slightest hesitation?"

"I'm just stating facts. Nothing to be embarrassed about."

I worked my middle finger. Whether she hadn't properly masturbated while we were apart or not, her insides felt tighter than before.

Squelch. Squish.

"Hnn… haah…. Yu… jin… ahng."

Jin Seyeong's body shuddered, and the pussy clamping down on my finger convulsed.

"You came already? Even for you, that was way too fast. How backed up were you?"

"The last time was… months ago… hnn…!"

I pulled my finger free and held it up. Clear, sticky fluids glistened on it, still warm from her body heat.

"Yujin…."

Jin Seyeong looked at me with heated eyes. What she wanted was obvious. If I told her to shake her ass for me right now, she'd do it without a second's hesitation.

I grinned and just watched her in silence until she moved first. Before she could grab my cock, I flopped onto my back on the floor.

From below, her breasts looked even fuller, and the ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠sight of her pink pussy gaping and dripping was completely unfiltered.

"Yujin?"

"Noona. We haven't seen each other in forever — we should do that thing."

"…What thing?"

"Don't play dumb. You know the one you're good at."

"……."

Jin Seyeong shut her mouth and hesitated. Her gaze drifted to my cock standing rigid. Her throat bobbed as she swallowed.

"Really… I guess I don't have a choice."

She came closer. Her legs settled on either side of my waist. Plop — a drop of her juices fell and landed squarely on my cock. She shifted her legs this way and that until she found the perfect position, then dropped into a squat.

Both hands went behind her head. Her hips began to lower, slow and deliberate.

Slick.

Cock met pussy.

"Haaaah…."

Jin Seyeong stopped. She should have come down farther. After so long, she seemed to be feeling a little resistance. I waited patiently, admiring the pale undersides of her arms.

Her pussy descended again, slowly swallowing my cock. It was so tight I half expected to hear it creaking. The sensation of her walls stretching around me never got old, no matter how many times I felt it.

"Hhk… haaaaaah!"

Her hips froze with my shaft only halfway inside. Her pussy clenched without rest. Jin Seyeong opened her mouth, exhaled a scorching breath, and lifted herself back up. The sex squat had begun.

"Hiiik… hhk… haang!"

She seemed content taking only half of me — but I was starting to get impatient.

Time it right….

The moment her hips came down, I drove my own hips up with everything I had. My cock buried itself to the hilt.

"Hnnnngh?!!"

Jin Seyeong lost her balance, staggered, and finally her legs gave out — she ended up straddling me fully. She pressed her palms against my chest, barely keeping her upper body from collapsing.

"Ah… aah…. I don't care anymore. I'm doing this however I want. Hnn… haaaang!"

Her movements turned rough. She cast everything else aside and chased pure pleasure. Her hips worked so fast it looked like she had four asses. The palms planted on my chest pressed down with real force.

"Hnnnnngh… again…. I'm coming againnn!"

Her ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠whole body jerked and twitched. Then she dropped her face to mine and kissed me like she meant to devour me.

For two straight hours, Jin Seyeong rode me without rest. When she finally collapsed on top of me with a look of pure satisfaction, her lower half was soaked with cum and her own juices, and my cock was still buried inside her.

I ran my palms over her waist and the curve of her ass. Trained firm, slick with sweat — the texture under my hands felt good.

"Noona. Heading straight back to work?"

"If I want to finish Scattered Thunder — the Extreme Technique I created — I need real combat experience. Not right away, though…. I'll rest about a week, then head into a dungeon."

"So you've got a whole week to hang out with me."

"I do, but… I'm not planning to just play around. I'm going to renovate the Yeongcheon Sword Dojo."

"Renovate? Why?"

"…The facilities at the Yeongcheon Sword Dojo just aren't enough for us to train properly anymore. Don't you think?"

I couldn't argue.

Maybe it would have been fine before. But now that both of us had reached A-Class, going all out would tear the place apart. Proper training here meant renovations were non-negotiable.

"Anyway, that means we've got a week together. A week disappears fast — we can't just lie around like this."

I got up, flipped Jin Seyeong onto her stomach on the floor, grabbed her ponytail, and snapped my hips forward.

"Ah…. That hurts, Yujin."

"Says the one dripping pussy juice all over the place."

"Aaaang! Ahng, ahng!"

Slap. Slap-slap. The wet sound of flesh meeting flesh kept echoing through the Yeongcheon Sword Dojo for a long while after.
