The Instructor's Debt
"Hngh… please… not my ass…"
I rubbed the toy—slick and wet with Lee Donggeul's saliva—against Hong Eunyoung's anus. With one hand I locked onto her waist as she kept trying to squirm free, hauling her back toward me. The hips that had been bouncing so eagerly around my cock had no choice but to freeze.
Trying to thrash around and do everything at once was a bit much.
The toy was thinner than me. Longer, yes—but at that girth, even a first time should take it just fine. Provided she stopped clenching so hard.
"Relax. Tensing up only makes it hurt more."
"But… but I'm scared… please…"
"And who, exactly, has been doing this terrifying thing to Miss Donggeul all this time?"
"Hic… I'm really sorry. Please, just forgive me this once…"
"If you don't relax, I'll force it in. That'll hurt several times worse."
I shoved the toy hard. Every time she clenched her cheeks shut I wrenched them open again. At first her anus refused to yield even a hairline crack—then, as if it simply couldn't hold out any longer, it began to give.
"R-relax."
"Hnnngh… kh… noooo… hngh…"
Everything is hard the first time. The moment the entrance opened, all that clenched force suddenly drained away—and her body swallowed the toy as if it tasted good. At the same instant, the walls of her pussy convulsed around me in a violent shudder.
"Hah… hah… augh… it hurts… my stomach, my lower belly feels weird… my ass is burning… take it out, please. Please, I'm begging you. I'll do anything you say."
I eased the toy out—not all the way, just enough to leave the tip still nestled inside. Hong Eunyoung's belly rippled in violent waves, and her pussy clamped down on my cock like a fist. I had deliberately left the tip in, yet the sheer force of her sphincter pushed the whole thing free on its own. Her stretched hole snapped shut so tight that the pressure on my cock turned savage.
"Haa… haa… haa… this is weird… I hate it…"
She was gasping like she'd just finished a marathon, clothes and all. Lee Donggeul, who had been grinding her pussy against Hong Eunyoung's face, shifted around beside me. From there she started filming her instructor's ass. The way she swallowed hard told me she found the whole thing fascinating.
One wrong move and that could have been her own ass. What the hell is she thinking right now?
Then she opened her mouth.
"Team Leader-nim… can I put it in?"
"Huh?"
"I want to try."
"…Go ahead."
I agreed. There was no world in which I said no. Technically, this revenge belonged to Lee Donggeul, not me.
I spread Hong Eunyoung's ass cheeks with both hands and started rolling my hips again. Meanwhile Donggeul took the long black toy, rubbed it against the instructor's hole the way I had, then forced it straight in.
Hong Eunyoung's sob-choked moan rang out loud.
"Hnnngh… stop… please stop already… my ass feels so weird…"
"You're so cute, Teacher. Don't worry. I'll heal you when we're done."
"Take it out… please… it hurts so much… ??!! Kh—! A-ah, no, how deep are you going!? Not deeper—uugh…"
Donggeul drove the toy in far deeper than the two finger-joints I'd managed. Instantly something extraordinary happened inside Hong Eunyoung. I barely needed to move my hips—the relentless clench and release of her pussy alone was more than enough stimulation. A massive tremor. A brutal urge to cum crashed over me, and I emptied myself straight into her.
Spurt… spurt-spurt…
"……?!"
"Hah… hah… make sure you take the morning-after pill…"
"Hic… no… if you cum inside… what am I supposed to do… you're so cruel. Sniff…"
I eased myself out. White fluid trickled from her pussy in a slow rivulet. The cocktail of scents was dizzying—if I hadn't just finished, the smell alone might have finished me off. Mixed into that thick perfume, colorless, odorless pheromones had to be saturating the air.
Which explained why Lee Donggeul kept rubbing her own pussy without pause. She was masturbating while still pumping the toy in and out of Hong Eunyoung's ass. The second I pulled free, she claimed the spot I'd vacated.
Have I been the only one having fun?
Then I should help a little.
I settled in behind Donggeul as she admired Hong Eunyoung's rear view, and began stroking her waist and belly with both hands. Inevitably those hands found their way to her beautiful, generous breasts.
"Haah… Team Leader-nim… my body feels weird."
"Where?"
"Everywhere—and especially my pussy. It's all tingly."
"I'll help. If my hands find a spot that feels good, tell me."
"Hnn… Team Leader-nim, do you like my breasts? You always go straight for them."
"Of course. Where else am I going to find tits this pretty and soft?"
"Teacher's are big too."
"Still prefer yours, Miss Donggeul."
"Hnn… Team Leader-niiim… there… the nipples feel good… mmm…"
Even while savoring my touch, Donggeul never stopped tormenting Hong Eunyoung's ass. The instructor begged her to stop; Donggeul showed no interest in listening.
"My pussy too… touch my pussy with your hands, Team Leader-nim. Haah…"
"Alright."
The moment my fingers replaced the ones she'd been using on herself, she flinched—then melted into the sensation. A second later she took the hand that had been on her own pussy and slid it into Hong Eunyoung's cunt.
Donggeul was working Hong Eunyoung. I was working Donggeul. In my imagination this would have been heaven. Right now it felt like the middle of hell.
"Haah… hnn… Teacheeer… does it feel good?"
"Hic… stop already… please… my ass is burning… I can't even use mana anymore… kh… just stop…"
"It's fine. I can heal more than ten times now. I'll fix you up. So even if it hurts a little, bear with it."
Slap!
"Hgggk… no… if you hit me while it's still in my ass…"
Slap!
"Kh… I'm sorry. I'm sorry, Donggeul… please… Teacher's a bad bitch, so just stop…"
Having already cum, I was relatively clear-headed, watching the two women with a strange mix of feelings. Lee Donggeul and Hong Eunyoung's positions had flipped a full one-eighty. And yet this wasn't quite the same texture as simple payback for past humiliation. Donggeul was genuinely savoring the pleasure. Hong Eunyoung, for her part, seemed to be genuinely repenting her past.
Irony didn't get more ironic than this.
"Haah… Team Leader-nim, can you see? Teacher's so cute, right? Right?"
"Yeah…"
I was starting to want this over. I had no desire to cum again—and even if I did, I needed to hold back. I was meeting my senior tonight; overdoing it now would be a disaster.
So I cranked Donggeul's pleasure to the absolute limit, working her pussy and clit like my hands had motors bolted on.
"Hngh… Team Leader-nim… I… I'm coming. Hyaaah—hnnn."
One hand drove a long middle finger deep into her cunt; the other rubbed furiously around her clit. Sitting behind her like this, I had a perfect view of those full breasts and stiff nipples over her shoulder. Looking at that soft flesh made me want her all over again.
But I still had an afternoon mana test, and all I'd eaten since morning was a single roll of gimbap. I was starving.
"Khnn… aaah… good. So good. I love it, Team Leader-nim."
Whether she was cresting into orgasm or not, Donggeul leaned back against me. Fully absorbed in her own pleasure now, she pulled both hands off Hong Eunyoung and started kneading her own breasts instead. I turned her head and brushed a light kiss against those cute lips, never stopping the work on her pussy.
"Mmm… mmph… mmmmmn—!"
Kissing me, Lee Donggeul finally came. Whether she'd always been into women or whether today had simply opened her eyes to the S-side of things didn't matter in the slightest. The sweet, addictive rush of rising mana under my ability was something no Awoken would ever willingly let go of. And the pleasure that hit the instant her mana climbed was every bit as satisfying as orgasm itself.
Donggeul tasted pure ecstasy under my hands. Her mana rose higher than before. As if to prove me right, even after my fingers left her pussy she still kept her tongue buried in my mouth, refusing to let me go. That soft tongue toyed with the inside of my mouth, greedily sucking down my saliva like it was delicious.
Hong Eunyoung watched the two of us with something that looked a lot like envy.
"So this is the instructors-only cafeteria? The facilities are insane. Are you sure it's okay for me to eat here?"
"Yes… if I say I authorized it, there won't be a problem."
"Team Leader-nim. How is it? Academy food's good, right?"
"Yeah. Excellent."
Hong Eunyoung led Lee Donggeul and me into a restaurant on academy grounds. Being reserved for instructors, top-tier facilities were a given—and apparently they even had some of the best chefs in the country on staff. Instructors were all high-flying Awoken; keeping that crowd happy would require nothing less.
The proof was in every bite: textures and flavors I'd never experienced before lit up my mouth. The kiss with Donggeul was already fading into memory.
"Miss Hong Eunyoung."
"Yes."
"Mind if I use your name? You are an instructor, after all."
"I don't mind. You're not one of my students."
I gave her a light smile and needled her a little.
"Don't you have class this afternoon? You're going like that?"
"Yes… why?"
"You reek right now… pheromone scent. You can't smell any of these incredible dishes at all, can you?"
"……"
No answer. Hong Eunyoung looked away, face flushing red.
Huh. I had her pegged as a psycho who only goes after kids—but looking at her like this, she almost seems like a shy girl.
You really can't judge people by appearances.
Beside me, Lee Donggeul was locked onto her meal. The more I watched her, the more obvious it became: this girl genuinely loved food. Even with her right there, I decided to show my ugly side. Once I started the company I planned to bring her along anyway—we were basically accomplices at this point.
"Eunyoung."
"Y-yes…?"
Every time I said her name, Hong Eunyoung jumped. The reaction was so entertaining I kept doing it. Was that just my nature?
Looks like hers and a personality like that—guys shouldn't have left her alone… though being Awoken raises the bar, and male Awoken are everywhere too… is it because she's into women?
Ah. Save that thought for later. First, the main point.
"Your punishment isn't over yet."
"……"
Her expression locked up solid.
"But you don't need to worry. Do what I tell you, and I won't expose your secret—and I'll stop punishing you. I'll even give your mana back."
"What exactly do I have to do?"
"First principle: you don't continue the work you've been doing. That's non-negotiable."
"Of course. I absolutely won't."
I finally got to the real point.
"You're rich, right?"
"What? Money?"
Hong Eunyoung's face said so it comes down to money after all. At first she looked contemptuous; then gradual relief crept in.
Don't go thinking 'just pay and it's over.' That would be a mistake.
"Instructors still go into dungeons sometimes, don't they? And you weren't always an instructor… so you've built up a decent pile, right?"
"Yes… how much do you want?"
I liked how fast she cut to it.
"As much as possible."
"Would five hundred million won work?"
Five hundred million, just like that. Just how much money were these Awoken bastards raking in? Still—it was less than I'd been thinking. I'd planned to strip her of everything she owned. I'd figured twenty billion wouldn't be out of reach. Hearing her toss out five hundred million so easily changed my mind.
"Five billion."
"Wh-what? I don't have that kind of money."
"Then you'll be visiting my room every night from now on. Bring a healer with you. Miss Donggeul won't always be on standby."
Her face went paper-white. The second I implied the punishment would stay focused on her ass, she went rigid. Had today really been that rough? Donggeul's heals had already fixed her, and she was still acting like this.
"I really don't have it… I could maybe scrape together one billion, but…"
"Fine. One billion, then."
"Hah… thank you."
"Getting ahead of yourself. We're not done."
"What else is there…?"
I gave the dejected woman a bright, wide smile. I was smiling, yes—but it was not a pleasant smile. It was the greasiest, most vicious grin I had.
