6. I Became an Academy Veteran in the Novel

Once Jiyoon had come back down to earth, we cleaned ourselves up as best we could and gathered around the table.

Inside the camp, the silence was crushing — like someone had dumped a bucket of cold water over the whole place.

Yoo Seolha was the first to break it.

"Did you two... actually hit it off or something?"

I traded a glance with Choi Jiyoon. She answered first.

‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠

"You already know how much Ian cums. I figured there was no way I could keep swallowing all of that, so I tried something different. But—"

I picked up where she left off.

"I absorbed four whole mana in one go."

Seolha's eyes went round as saucers.

"Four? It went up by four?"

Jiyoon and I both nodded. After all, it took painstakingly sucking off my big cock and struggling through all that cum just to absorb a measly two. One creampie, and she'd taken in four just like that.

Seolha mulled it over for a moment before speaking up.

"Still, I don't think this is the way, Instructor. What if you get pregnant? I know you can lower the odds with mana control, but... there's still like a two percent chance."

"Seolha, this is good news. You don't have to do it anymore. If I do it with Ian, I can refill mana in no time."

Both Choi Jiyoon and Yoo Seolha had over 50 mana, and mana normally regenerated one point every ten minutes. After a decent night's sleep, you'd be sitting on a full tank, ready to absorb more.

"...I really don't think I can ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠do it. I'm sorry."

Choi Jiyoon had a Status Window skill too, but unlike me, she couldn't read minds along with it. Even so, somehow she'd sensed exactly what Seolha was feeling, and she reached out and clasped her hand tightly.

"Seolha, everything you've done so far was more than enough. From now on, I'll handle Ian and keep our mana topped up."

Seolha lifted her head.

"In return, I'll take over everything else. Cooking duty, cleaning... and if there's ever a time he needs it done by mouth, I can help with that too."

"Good. That would be a big help. Shall we head for the next Safe Zone, then?"

We rose from our seats. I gave Choi Jiyoon's outfit a sidelong look.

"Jiyoon, I think a skirt would be better. Just in case."

Meaning: if we suddenly needed to draw mana mid-dungeon, a skirt you could flip up and mount on the spot beat tights that had to be wrestled off.

"Huh. Good point."

"...Jiyoon... ah?"

Seolha's eyes darted back and forth between the two of us. Jiyoon explained.

"Ah — I told him to drop the formalities. Calling me 'Instructor' while we're... doing that would be ridiculous, wouldn't it? Actually, this works out. You should call me unnie too, Seolha. In a crisis like this, growing closer and binding together is what matters. Of course, once we're back at the academy, you'll have to call me Instructor during class."

Seolha nodded.

"...Yes. Unnie."

We broke camp. We could have stayed put for the whole day, letting me creampie Jiyoon over and over to fatten up her mana tank before leisurely resuming the dungeon tomorrow. But—

They'll be thinking the dungeon could end at any moment.

So we left the Safe Zone and pressed on with the delve.

The very next room drained my mana dry. A single mana stone clattered to the floor.

"I'll go scout the next room."

Seolha darted ahead to count the monsters, then came back.

"Skeletal wraiths. Five of them."

I seemed to recall from the novel that rooms with more than five monsters were rare in dungeons. Whatever the case, Jiyoon wasted no time pulling down my pants and crouching in front of me, her mouth already working my cock.

I rested a hand lightly on her head.

"One creampie within thirty minutes, then one more from your mouth."

"Mm."

Jiyoon looked up at me with a diligent expression, her lips sliding up and down my shaft in steady rhythm. Beside us, Seolha fidgeted awkwardly.

"D-do you need me to help with anything?"

"Seolha, you keep time from over there. And after the creampie, you take over with your mouth."

"O-okay. Got it."

My training big cock, freshly serviced with a blowjob, hardened to full mast.

"Jiyoon. Brace yourself here and stick your ass out."

"Like this?"

I had her plant her hands on the cavern wall and present herself to ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠me. I flipped up her skirt, tugged down her panties, and drove my cock straight into her dripping pussy.

"Nngh."

Jiyoon threw her head back, fighting to stifle her moans. I began pounding away inside her.

Slap, slap, slap, slap.

Obscene sounds rang out crisply through the dungeon room — her lewd pussy and swaying ass, doing their damnedest to wring out my cum. Seolha watched us from the side, gulping audibly.

I hammered into her without pause, and eventually Jiyoon's dam broke — the moans she'd been choking back came flooding out.

"Mmph... nngh... aahhn... Ian..."

"Yeah?"

"I... I think I'm gonna..."

"Want me to pull out?"

"Nnhh. No — no time. Keep going."

"Got it."

Slap, slap, slap, slap.

"Aaaaahn♥"

Right in front of Seolha's watching eyes, Jiyoon came all over my cock and started squirting uncontrollably. Her plump ass convulsed against her own will, and every time I bottomed out inside her, a fresh burst of her juices sprayed out around me.

Slap, slap, slap, slap.

I kept up the piston rhythm without mercy.

"Seolha."

"Yeah?"

"Come here and let me play with your tits."

"O-okay!"

Seolha, eager to be useful, came over to my side. Still buried in Jiyoon, I pulled Seolha into my arms.

"Hold still. I'll undo the buttons."

She unbuttoned her combat uniform of her own accord and let me fondle her bare breasts. Holding her against me, I seized both breasts tight in my grip and kissed her. Startled for a split second, Seolha had no choice but to accept my kiss.

No — this is my first kiss. My first kiss is supposed to be...

But Yoo Seolha was a pragmatist. I had to make her cum twice in thirty minutes. On top of that, something seemed to be gnawing at her — the sight of everything being left entirely to Choi Jiyoon.

Fine. At least... this much. I'll think about the rest later.

Little by little, Seolha's tongue began tangling with mine in earnest.

So Jiyoon came twice more, and then my own climax came surging up. I picked up the pace of my thrusts.

Slap, slap, slap, slap.

"Ahh — cumming. Jiyoon."

"Mmnh. Give it to me. Cum for me."

"Ahh."

I grabbed her ass with both hands and pumped her pussy to the brim with semen.

"Aahhhnn♥"

She rode out another orgasm as I filled her, the S-class hunter with her legendary stamina — Choi Jiyoon — her legs trembling like a newborn fawn. When I finally pulled out, cum came gushing from her hole in thick, dripping waves.

"Haaahn..."

At last she collapsed to her knees on the floor. I turned to Seolha.

"How much time's left?"

"Fifteen minutes."

"Suck."

"Okay."

Seolha crouched in front of me and took my cock into her mouth. Even coated in semen, she sucked it without a hint of disgust — if anything, savoring it.

I glanced at Jiyoon, still sprawled face-down and panting.

"Jiyoon, you okay?"

"Mm-hm. Don't worry about me. Just keep going... nngh... haahn."

Her lower body was still quivering, semen trickling steadily out of her hole.

I took Seolha's head in both hands as she sucked. She looked up at me.

"We're short on time, so I'll do the work."

Gripping her head, I began pistoning my cock in and out of her mouth like it was a fleshlight.

"Ulp. Mph. Uuum!"

Seolha slapped at my thighs, but I ignored her and kept driving my cock down her throat. The Big Cock for Training was working exactly as advertised. The longer I made her savor the taste of my cock, the weaker her slapping hands grew. It felt like her mouth was being developed into exclusive property of my dick.

My cock is invincible, and my cum is godly!

"Uum. Uuum."

When I glanced down, she was glaring at me like she wanted to murder me.

"You're doing great, Seolha. Just a little... a little more."

I kept using her mouth-pussy until Jiyoon had recovered enough to move again.

"Uum. Mm."

"What is it?"

Even as I asked, I didn't pull out of her mouth. If anything, I fucked her face faster.

"Uuuuum."

Her glazed eyes slowly rolled back, and her slender waist began to shudder. Yoo Seolha — cumming while sucking my cock. I finally withdrew from her mouth.

"Hah... hahhh... that's too much... hahh..."

Seolha crumpled to the floor.

"Good girl."

I stroked her head, then made my way back to Jiyoon, who had already braced her hands against the cavern wall and was presenting her ass to me.

"Spread your legs a bit more. Good. Putting it in?"

"Yeah. Nngh!"

I sank my thick shaft back into Jiyoon and resumed the piston work.

Slap, slap, slap, slap.

"Jiyoon."

"Nnngh."

"Cumming?"

"Cum. Cum for me."

"Ahh."

Ropes. Thick, endless ropes of it!

There was a reason they called it High-Capacity Pleasure Semen — no matter how many times I came, the stuff just kept firing out of me like a burst hose.

"Aaaaaahn♥"

As I churned my cock around inside her, cum overflowed from her pussy in creamy gushes.

Ding.

My mana had gone from 4/5 to 5/6. Once it hit the old cap at 5/5 and filled completely, it expanded the tank by one.

So filling it to the max overfills it, and the overflow widens the tank by one as a bonus. Clever — that dangling single point just makes you want to keep filling it.

"Girls. Let's move."

We crossed into the next room.

A mana stone dropped. We made it to the next Safe Zone, my cum still running in a slow trail down the inside of Jiyoon's thigh.

"I'll scout the next room."

Seolha set up the camp without being asked. She and I stepped inside, and a little later Jiyoon crawled in after us.

"Three skeletal wraiths. And there are more rooms beyond that."

"Instructor — no. Jiyoon unnie. Wash up first."

Choi Jiyoon gave a wry little smile.

"When you call me unnie, you can drop the formalities too."

"Mm-hm. Go wash first, unnie."

"Thanks."

Jiyoon headed into the shower. I dropped into a chair at the table.

"You did good too, Seolha."

"Say what now?"

Yoo Seolha, standing beside me, fired off a light jab.

"A cocky little F-class, acting all high and mighty—"

Her small, soft breasts pressed snugly against the top of my head. Absently, I turned my face toward them — and my nose and mouth sank straight into her cleavage. Seolha looked down at me. Her face was flushed, but she neither flinched nor pulled away.

I moved slowly, undoing the front of her combat uniform. Pale, flawless breasts came into view, her light pink nipples standing stiff and erect. Licking upward to meet her eyes, I flicked my tongue over one nipple. She murmured, barely above a whisper.

"If you want to suck it, you can."

I didn't need telling twice. I drew the nipple into my mouth and sucked, and Seolha's whole body gave a jolt. My hands slid down her narrow waist and seized both cheeks of her ass. She began stroking my hair.

"Fine. When you need to cum, you can go this far. I'll allow you this much."

I licked her nipple one more time and looked up at her.

"That's not gonna cut it, though."

"Huh?"

I led the bewildered girl to the bed and laid her down, pinning both her arms above her head with my own.

"Hah — hey. You keep pushing and pushing, and—"

"You saw what happened in the dungeon, right? Jiyoon can barely handle me alone. If this dungeon drags on, you'll ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠be taking creampies sooner or later anyway."

After this dungeon arc wrapped, the original protagonist Kim Seonghyeok's long stretch of blundering began in earnest. What readers actually wanted was the hero flirting around at school — but the author, apparently sick of the academy setting, up and shifted the story to a tower, then overseas. As a result, the main heroines got left behind, and a hostile faction began infiltrating the academy. The story did eventually get back on track, with the protagonist returning from break to rebuild the crumbling academy — but I intended to stop that whole catastrophe before it ever started.

And to do that, I'd need not just Choi Jiyoon but Yoo Seolha trained to obey me in advance.

Seolha shot back at me.

"You just want to fuck me. Admit it."

"Do you?"

"..."

"You just let me suck your nipple, remember?"

Seolha whipped her head away.

"Th-that's different."

I caught her chin and turned her face back toward me.

"Down in the dungeon, I forced my cock into your mouth, and you got so worked up you came."

"I did not. Don't flatter yourself."

"So you'd rather leave Jiyoon to suffer alone? You saw it yourself — after taking a creampie in the dungeon she could barely move."

Seolha went quiet for a moment.

Sob... so it really has to be with him? If I do it with him, then me and Seonghyeok are totally...

Apparently, at this point in the timeline, Seolha and Kim Seonghyeok had something of a flirtation going.

She wasn't the heroine I was chasing, so the details are fuzzy.

After wrestling with it, she finally spoke.

"Can you finish before unnie gets out of the shower?"

Seolha's cheeks went red; she stole a glance at me, then quickly looked away again.

"Don't get the wrong idea. It's not that I want to sleep with some lowly F-class like you — I'm doing it to help unnie."

I smirked.

"Sure. As long as you don't make any noise, I won't get the wrong idea."

And I kissed Yoo Seolha.
