Chapter Title: Seoyoon's Demonic Energy Infusion
-----------------------------------------------------------------
With my cock buried deep in Seoyoon's pussy, every time I channeled demonic energy into her, it triggered an orgasm that made her walls clench around me in a way that was anything but ordinary.
Was it different from the pleasure I'd shared with Yejin, Miyoung, or Sohee up until now?
Sex with those three always built up to a peak of excitement, where they'd climax and squeeze as if begging to be impregnated.
But Seoyoon was different. It felt like she was being forced into near-orgasm every time I injected demonic energy.
"Ha, haaa..."
Overwhelmed by the relentless waves of ecstasy, Seoyoon's mouth hung wide open, her tongue lolling to the side as she lost herself completely.
I hadn't even thrust properly, yet here she was, practically passing out from orgasms. It was starting to unsettle me.
"Hey, you okay?"
I tapped her cheek lightly while still inside her, and her dazed eyes regained a bit of focus.
"F-Fuck, I'm fiiiine..."
"Yeah, right... You're completely out of it."
This wasn't even qualifying as proper training. I decided to call it quits and started lifting her off my cock.
But then Seoyoon weakly wrapped her arms around me.
"Hey, looking at you, we should stop here. Let go."
"N-Nooo... I c-can do it!"
Just as I opened my mouth to tell her not to push herself, the demonic energy I'd sent toward her dantian began to writhe, seeping into it.
She wasn't controlling all the demonic energy I'd injected, but even absorbing a tiny amount into her own dantian on her own was a massive breakthrough.
Up until today, she couldn't even hold demonic energy in her dantian, let alone handle it proficiently.
This was the first time I'd tried directly injecting demonic energy into her body and guiding it to her dantian, so I had no idea if it would work. But damn, the results were better than expected.
Whether it was just a good method or one that suited Seoyoon perfectly didn't matter.
As long as her skills improved, that was all that counted.
"Haa, haa... M-Master, please... keep going..."
Seoyoon clung to me fully, resting her face on my shoulder, whispering breathlessly into my ear.
If she insisted she was fine, then it was time to get serious.
"Alright, focus up and accept the demonic energy."
"Y-Yes, Master!? Ahh!"
Up to now, I'd just kept my cock inside without much movement. But this was the starting gun—I slammed it deep into her pussy with full force.
Feeling my cock plunge into her depths made her juices drip down, and when I added demonic energy, her walls contracted wildly, trying to milk me dry.
Of course, just storing demonic energy in one's dantian wouldn't produce the same reaction in me.
There was no record of handling one's own demonic energy and storing it causing special changes in the body.
But there were no cases of someone else directly implanting it into the dantian either.
"Ha, haaang! Hngh! Haaah!"
As I rocked my hips, stirring her insides with my cock while pumping in more demonic energy, Seoyoon came again and again, squirting juices, yet somehow controlled a portion of it to draw into her dantian.
And I could feel that tiny amount gradually increasing.
Thrusting my cock makes her black magic improve? Talk about a scenario straight out of some erotic tale.
Maybe that's why my cock was harder and bigger than usual.
"M-Master! It's too gooood! I-I'm gonna go crazyyy!"
"What feels so good? Say it clearly."
"Every time Master's cock thrusts in! It feels like my insides are exploding—it's driving me insane!"
Even as she answered, Seoyoon didn't lose control of the demonic energy.
What a dedicated disciple.
With my cock pounding her, pussy gushing fluids, eyes rolling back, drool dripping from her mouth—she still maintained her demonic energy control. It showed just how desperate she was to master black magic.
"Alright, here it comes—I'm gonna cum!"
"Y-Yes! Master!"
The building urge to release was too much to hold back. I flooded her pussy with a massive load of cum.
"Ah, aah!? Haaaaaaaah!"
Seoyoon let out a scream incomparable to before.
Because as I came, I'd packed my cock's release with concentrated demonic energy.
Until now, unsure if it would work, I'd only fed her small amounts.
It wasn't verified, so if it had no effect, fine—but if it harmed her, that would've been disastrous.
Testing gradually with tiny doses during sex had confirmed it was safe, so this time I infused the cum itself with demonic energy before unleashing it inside her.
"Hngh, hiiiik! Eek!"
Shaking like a fish electrocuted from the concentrated demonic energy, Seoyoon could do nothing as I slowly pulled my cock out of her pussy.
"Haaang!"
The cum I'd poured into her pussy started dripping out.
"Can't let that precious load go to waste."
Especially since I'd infused it with demonic energy myself.
I pulled a dildo from my subspace—one I'd prepared in advance—and shoved it into her pussy, slick with our mixed fluids.
"Hauk!"
Stroking her sweat-soaked hair, I spoke softly.
"Absorb as much of the demonic energy in that cum into your dantian as you can before it dissipates. Keep the plug in—no letting it leak out."
"Haa, haa... Yes, Master..."
Her voice was utterly exhausted from me stimulating her dantian with demonic energy while buried inside. I pressed my cock to her lips.
"There. After sex with me, always finish with a cleanup blowjob. Got it?"
Seoyoon nodded faintly, sticking out her tongue to lick the remnants off my cock bit by bit.
Totally spent and dazed, she didn't care that it was coated in my cum and her own juices—she cleaned every inch like it was ice cream.
Slurp, slurp!
Suddenly, a weird sound caught my ear. I looked over to see Seoyoon working the dildo I'd plugged her with—in and out herself.
Never expected her to masturbate with it in this state.
While still absorbing the demonic energy inside her, of course.
If the demonic energy I put in today was 10, she was absorbing maybe 1 or 2.
The rest just dissipated into the air, which felt wasteful, but her massive progress made it a worthwhile investment.
Honestly, I never imagined it'd work this well.
Occasional sex sessions to stimulate her dantian might be a solid method.
I get off, she gets orgasms and better demonic energy control—win-win.
I carried Seoyoon, still fucking herself with the dildo on the floor, to the bed, then grabbed my clothes and headed back to my room.
After a quick shower, I lay down, and Yejin—who'd been sleeping—snuggled into me.
Wondering if I'd woken her, I started to speak, but she just pressed her face to my chest in silence.
I didn't say anything either, just gently stroked her hair and closed my eyes.
Then Yejin spoke first, her face still buried in my chest.
"Where'd you go? To Seoyoon's?"
I'd mentioned Seoyoon before leaving the room earlier, so she'd guessed right.
"A new idea for boosting her black magic came up while talking with you. Just came back from testing it."
"Did it work?"
"Not dramatic growth, but she's definitely crossed the starting line."
"How'd you do it?"
I told Yejin everything that happened with Seoyoon.
"Whoa... It's crazy that even works. Sex to get stronger."
"Even I'm stunned now that I've done it. Never thought it was possible."
"Oppa, then... what if I..."
I knew exactly what she was going to say, so I lightly flicked her head against my chest.
"Ow! Why'd you hit me..."
"You were about to ask me to do the same to you. That's why."
"Well, yeah, but... if you tried it on me, maybe I could use black magic too? Worth a shot!"
I flat-out refused Yejin, but she kept begging for just one try.
Seemed like I wouldn't get any sleep at this rate, so instead of arguing, I showed her directly—fucked her the same way as Seoyoon.
As expected, nothing happened.
No matter how much demonic energy I put in her, she couldn't even sense it.
Disappointed she couldn't learn black magic from me, Yejin decided to make the most of it and kept sucking my cock, refusing to let go. After three loads in her pussy, we finally finished and fell asleep.
The next day, as I opened my eyes, a system window appeared.
Looks like there's been some kind of patch.
