Reverse Dungeon

"You thought I was good at it?"

Keith asked before he could stop himself.

"Be quiet."

A sharp reprimand came from his master.

Ian sat him down and climbed onto him, and Keith obediently closed his mouth.

Settling boldly onto his thighs, Ian wrapped a hand around him. He spread his legs, intending to guide him between them, but for some reason paused and looked down at Keith.

"Would you like some help?"

"Why is it getting bigger?"

Judging by his tone, what Ian meant was, why is it getting even bigger now?

Keith found himself at a loss.

"Because you are touching me so kindly, Ian. It is naturally made to grow under such circumstances. If you ask me why it grows, I truly have no answer to give."

"No, I..."

Ian parted his lips, but failed to continue. He merely stared downward with a bewildered expression.

Tap.

Every time his fingers moved as though measuring its size, Keith twitched.

Keith wished it would stop.

Did it not seem as though Ian felt threatened?

Keith was aware that he possessed a larger build than most of the other Holy Knights.

Since his frame was large, it was only natural that the rest of him had grown proportionately.

Until now, he had never cared.

Meeting Ian had changed that.

If only it were smaller.

Keith felt a pang of regret.

"Is it difficult to do it yourself?"

He asked, concealing his impatience.

He wanted to return to that warm place as quickly as possible.

To push into that narrow passage and bury himself inside it again.

The pleasant warmth he had held moments ago was gone, leaving his arms cold.

It was strange that that alone could make him feel lonely.

He wanted to hold his master.

He wanted to hold Ian.

"No."

"But Ian..."

"I can do it, so stay still."

Ian's command was firm.

For some reason, that made him swell even more.

"...?!"

Keith felt embarrassed, but he did his best to explain for the sake of his startled master.

"When you order me like that, it excites me."

"How exactly did I order you?!"

"Like frost itself... You speak in a way that leaves no choice but to obey. I enjoy it when you give me orders, Ian..."

As he spoke, something felt odd.

Was this functioning as an excuse at all?

It seemed unlikely Ian would find any of this convincing.

"Fine, I get it, so stop getting bigger!"

"It is not something I can control..."

"It's yours!"

"Ah, if you strike it like that..."

"..."

Ian's eyes widened.

Then he clenched his teeth.

Why was he making such a determined expression?

Before Keith could continue wondering, Ian lowered himself onto him.

This time was different.

Not onto his thighs.

Onto the precise spot.

"Haa..."

A breath escaped through Keith's teeth.

He could not find words.

An indescribable pleasure seized him.

"Ah, Ian..."

"Stay still... nngh..."

Ian began moving above him.

Stars seemed to flash before Keith's eyes.

The unparalleled pleasure filled him with ecstasy.

This could not be earthly bliss.

It simply could not.

He wanted Ian to experience the same joy he did, but a body worn down by days of overexertion could not properly withstand the overwhelming sensations.

He hasn't rested while preparing for the battle.

The strength drained from Ian's trembling legs.

Unable to support himself any longer, he collapsed forward.

In doing so, he took Keith to the deepest place within him and released without even managing a moan.

That was enough to break Keith's restraint as well.

The inner walls tightened around him as though biting of their own accord.

He felt himself being squeezed dry, while Ian merely trembled beneath the waves of sensation crashing through him.

"I'm sorry."

"Ah?!"

Keith thrust upward.

Finishing quickly would be easier on Ian as well.

Ian's body had been trained through Archery and physical conditioning, but his natural frame was not large.

Keith felt as though he could wrap one arm entirely around his waist.

Grasping his narrow hips to hold him in place, Keith moved.

"Ah! Ah?! Ah...!"

"...This is dangerous. Let me lay you down."

"Ah, too fast... nngh...!"

Ian seemed unable to hear him.

Still, Keith asked permission.

Was that not the duty of a servant?

And was it not also a servant's duty to understand unspoken consent?

Abandoning the chair, which was far too fragile to support both their weight, Keith laid Ian across the desk.

He lifted one leg and spread it aside.

He secured Ian's waist so that no matter how violently he moved, he could not drift away.

Then—

He drove himself into him as though hammering in a stake.

Thud. Thud. Thud.

Creak. Creak. Creak.

"...!"

Everything happened in an instant.

Ian's body convulsed as though struck by lightning.

A moment later, Keith's lower abdomen grew wet again.

Ian's inner walls relaxed like melted butter and welcomed the intruder eagerly.

Ian's hands wandered over Keith's head, shoulders, and chest.

Whether he was trying to pull him closer or push him away, Keith could not tell.

Mumbling incoherently, Ian gasped,

"I—again—!"

"You may do so again. It feels too good..."

"Nnghh...!"

Ian shook his head, though whether he was rejecting the idea or merely reacting to the pleasure was impossible to tell.

Keith should have guessed.

Unfortunately, he was in no condition for proper thought.

A little deeper.

Further inside.

Until they could become one.

"Ah...!"

"Haa..."

Emptying himself inside Ian once more, Keith embraced him completely.

Then, overwhelmed by emotion, he showered him with kisses.

Ian did not move.

Puzzled, Keith checked on him.

His eyes were closed.

When Keith lowered his legs, Ian could not support himself and simply slumped over.

He must have been exhausted.

The fatigue accumulated in his body had been too great to endure anything further.

Keith was not surprised.

He had already suspected as much.

He carefully cleaned the sweat from Ian's body and wiped away the fluid running down between his legs.

He dressed him again, then reequipped himself.

Afterward, he drew an artifact from inside his clothing.

The Fairy Queen's Necklace.

An artifact capable of incapacitating an opponent.

Ian had entrusted it to Keith, who fought on the front lines.

Because this unusual necklace could change its length to suit whoever wore it, Keith always carried it close to his chest.

"Use it when necessary. The cooldown is long, so be careful."

"What is a cooldown?"

"...It means that once you use it, you'll have to wait a long time before you can use it again. So use it carefully."

Ian's voice seemed to echo beside his ear.

When it is truly necessary.

Keith had already decided when he would use it.

This item should be used only to protect Ian.

Wrapping the pearl necklace around his hand, Keith gazed down at him for a long moment.

Once, Ian had been God's messenger to him.

Certainty about the future.

Hope.

An absolute master who wrapped confidence around others like radiant light.

Though he neglected his religious studies, occasionally spoke irreverently, and often lied while invoking God's name.

None of that mattered.

Ian was a perfect master.

If he was not someone sent by God, then who could be?

And Ian's own words had only strengthened Keith's belief.

"Protecting this dungeon is my duty."

"It just... is."

"I know that it is."

Ian could have deceived anyone if he wished.

But at that moment, he had spoken the truth.

Keith knew it.

Just as Ian had said, he simply knew.

If the dungeon fell, Ian would die.

God had granted Ian life and entrusted him with a mission.

Ian was God's messenger.

Ever since Keith had met him, he had never been anything else.

Yet at the same time, he was an ordinary human being.

"That's impossible."

"Run."

"Run."

"No. No, don't listen to me."

"You bastard. It's working! Why won't it shut off?!"

Keith remembered the sight of him trembling in confusion.

He had seen the future.

A future where the Demon King discovered the dungeon and trampled it beneath an army of mamool.

Ian had suffered because he feared that future.

Because it saddened him.

Like any ordinary person.

No.

He was an ordinary person.

Someone who hurt.

Someone who grieved.

Someone who could lose himself.

And yet possessed a stronger heart than anyone else.

The person Keith loved.

For a long time, Keith had wondered why the world was so full of despair if God truly existed.

God dwells in heaven and loves the righteous.

And so—

He watches as the righteous struggle, suffer, and try to save the world.

Having granted humanity free will, He hopes that those He has chosen will preserve their righteousness through death and enter paradise.

If God existed, then He desired Ian's death.

Keith wanted no such God.

He did not want a God who desired Ian's suffering, sacrifice, and death.

Meeting Ian had brought an end to his wandering.

The one who had saved him, dispersed the dark clouds in his heart, and allowed him to live beneath warm sunlight with endless gratitude was not the being in the heavens.

It was Ian.

Clink.

Keith fastened the pearl necklace around Ian's neck.

The necklace emitted a faint glow...

Then shrank until it fit perfectly around Ian's throat.

Keith kissed Ian's forehead.

You will not leave this place.

The Demon King would die.

But that task belonged to Keith.

He would protect Ian.
