The Cloaca

The place I arrived at, following Lee Han-seop, was an enormous underground facility.

An Irregular containment zone, divided into multiple sections by thick steel bulkheads.

"This is where we manage the Irregulars possessing the Immortal Attribute. Every one of them is held fully restrained in its own cell and monitored around the clock."

Lee Han-seop explained as he led the way down the corridor.

"Those are all monsters that came out of gates too?"

"Yes, that's right. But individuals with the Immortal Attribute simply cannot be eliminated through a hunter winning a fight alone. As far as the Management Agency is concerned, they're a massive headache."

This was news to me.

Based on the information floating around on TV and the internet, I'd always believed ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠that hunters currently active were handling every monster emerging from the gates flawlessly.

If word got out that monsters existed which couldn't be dealt with that way, it would sow anxiety throughout society, I supposed.

Suddenly curious, I asked.

"That's hard for me to wrap my head around. Couldn't you just kill them outright, or tear them to pieces? The fact that you can keep them locked up here means hunters can subdue them, doesn't it?"

"Well, you see."

Lee Han-seop's walking pace slowed a little.

"Naturally, we've tried every means available. We've had hunters with powerful abilities vaporize them until not even a trace of their form remained. The problem is that the 'Immortality' these Irregulars possess doesn't mean 'invincibility.' If the Irregulars held here ever reach a state from which recovery is impossible, by any means……"

"……Then what?"

"……They immediately reappear through a gate. Completely unharmed."

"Then what about the, um, Slime Cube I… dealt with?"

"No, that was a different matter. That slime cube simply had such overwhelming regenerative power that there was no way to clear it out."

An Irregular with the Immortal Attribute, huh….

If that was really the reason, then containing and imprisoning them here made sense.

Ordinary people like me, with no connection to Awakened ones, just went about their lives assuming everything was fine because hunters were protecting daily life from the gates — but in truth, there might be far more invisible difficulties on this side of things than we realized.

"Here we are."

Where Lee Han-seop stopped was in front of a massive steel door.

It was a door of thick metal, like something out of a space station in an SF movie.

It appeared to open from both sides, its joining seam shaped into an intricate pattern like interlocking gear teeth.

"The individual you saw on the monitor is inside. Normally it's a dangerous creature that generates Wind Blades sharp enough to shear through steel, but we've restrained its wings so it can't swing them. It shouldn't pose any danger."

"Then…"

"Yes. Go in and establish a 'relationship' with the individual inside."

I hesitated for a moment.

It wasn't that I felt burdened by the prospect of having relations with a monster resembling the harpy.

From my standpoint, as long as it turned me on, nothing else mattered.

The problem was the location.

This place existed to surveil Irregulars.

Which meant the room itself would be under camera surveillance twenty-four ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠hours a day as well.

Which meant I would have to devour a monster in front of the entire Hunter Management Agency.

No matter how much of my inner self I'd supposedly let go of, it would be a lie to say that wasn't daunting.

"Um…"

"Once you enter the room, Mr. Nam Tae-geun, we'll turn off the surveillance camera inside. Don't worry too much. And there will be a red button under a protective cap on the wall. It shouldn't come to that, but if a dangerous situation arises, just press it."

Lee Han-seop spoke as if he'd guessed exactly why I was hesitating.

Hearing his words, my heart felt considerably lighter.

"Now then, I'll open the door."

Lee Han-seop typed a complicated password into the touchpad mounted on the wall beside it.

Beep — hisssssss—

The firmly sealed door began to slide open, slowly.

Lee Han-seop raised a hand toward the entrance and nodded, gesturing for me to go in.

I took one deep breath, then stepped into the containment cell of the 'Immortal' individual.

* * *

Management code I-21. Individual designation: Harpy.

I'd thought it looked like a harpy — and sure enough, its official designation really was Harpy.

The moment I stepped into the cell, I heard the door seal shut behind me.

And there it was — the first living thing from a gate I had ever faced face to face.

I'd watched footage ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠of hunters fighting gate creatures on the internet until I was sick of it.

But who'd have thought the day would come when I myself would become an Awakened one and stand eye to eye with a gate creature like this.

"…"

Harpy hung from a steel cross on the wall, both wings bound in some special restraint configuration.

Sensing my presence as I entered, it lifted its head slightly and glared at me.

"Kii… kiiii…"

Harpy's long crimson hair spilled down in wild tresses.

Apart from the enormous wings and the hawk-like lower ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠body, its head and upper torso were in no way different from a human woman's.

Honestly, it was a beauty — setting aside the non-human parts, that is.

I looked at the surveillance camera tucked into one corner of the ceiling.

Lee Han-seop had promised to turn the cameras off while I did my job.

Which meant that whatever I did in here would never be seen by anyone.

I slowly approached the harpy hanging on the wall.

Up close, it looked even better than I'd expected.

The non-human parts were one thing, but the parts identical to a human were beautiful, and that was what counted.

The face glaring at me was porcelain white, the lips tinged pink.

The skin was smooth as ceramic — so flawless I could imagine its softness without even touching it.

Its bare upper body, naturally unclothed, bore a pair of breasts of just the right size — more than a single hand could easily hold.

"Kiii…! Kiii…!"

Harpy glared at me like it would seize and kill me the moment it got free.

It strained its wings against the metal cross, but they were locked fast and wouldn't budge.

As it thrashed, the harpy's pale, naked breasts swayed rhythmically.

"Oh…"

Watching that, my lower half began to stiffen and ache.

In truth this was an extremely dangerous being — but right now it was restrained and incapable of resistance.

It showed me unmistakable hostility, yet could do nothing about it — and that situation excited me.

Well then, shall I start with my hands?

I closed the distance until I could reach it.

Then I stretched my hand out over those completely exposed, tempting-soft breasts.

"Kiiiiii—!"

Softness.

The yielding weight of breast flesh filled my palm completely.

Having lived my whole life as a hopeless virgin, this was the first time I'd ever touched a real woman's chest, so honestly, it shocked me.

So this is how soft a woman's breasts are?

Well… technically not human, I supposed, but a human woman's chest probably wouldn't be all that different from this.

Carefully, I cupped the harpy's breasts in both hands, lifting them from below, and squeezed.

That subtle weight, that softness, that strangeness transmitted through my palms…

A flood of sensations crashed through my head all at once.

I had trauma around women because of my monstrous size.

Because of it, I'd grown passive whenever I had to deal with women, and I'd never managed a single relationship.

But the thing before my eyes was not human.

Maybe that was why — my hands showed no hesitation.

I kneaded the soft breasts to my heart's content, savoring the feel of the flesh spilling out between my fingers.

Harpy had thrashed at first, but once it seemed to realize resistance was pointless, it only let out strange cries.

"Hmm…"

Just from touching the harpy's breasts, my cock was already swollen rock-hard to the point of bursting.

I quietly pulled down my pants and underwear.

Even by my own standards, it was an enormous cock, standing erect at a sixty-five-degree upward angle.

A small bead of clear dew had already gathered at the tip of the glans.

"Kiii…"

Still hanging from the metal wall, Harpy lifted only its head, unable to take its eyes off my cock.

Did it properly understand what this huge thing of mine even was?

Well, it didn't matter either way.

I advanced on the harpy again, leading with a cock hard as stone, looking ready to explode at any moment.

The thought of bringing to life a fantasy I'd only ever seen in porn or hentai wouldn't let my excitement settle.

Left to my urges, I wanted to grab that crimson hair in one fist and shove my cock straight into its mouth.

But it would definitely bite me if I did that, so I decided to play it safe and try rubbing against its breasts instead.

"Ki… kiii…"

I pressed the harpy's breasts together with both hands and slid my cock between them.

Then I began to move, slowly back and forth —

"Hmm… this isn't quite the feeling I imagined…"

The soft, downy skin of the breasts against my cock felt wonderful, but the stimulation was lacking when I just humped between them like that.

I'd need lubricant after all.

In that case…

I moved to spit into the valley of the harpy's pressed-together cleavage — then froze.

The thought flickered through my mind that if I was going to do this, I'd rather use a woman's saliva.

But we couldn't talk, so how was I supposed to manage that…?

After a moment's deliberation, I gripped both of the harpy's cheeks hard with one hand, starting from the jawline.

The startled harpy's mouth fell open at once.

Keeping one hand tangled in the harpy's hair and the other clamped on both its cheeks, I forced its head down.

I felt it strain to lift its head again, but the strength behind it wasn't nearly as great as I'd expected.

I held the pose and waited, and soon saliva began to drip from the open mouth.

I caught the harpy's drool directly with my cock.

I kept the position until my glans was slicked and smeared thoroughly with that sticky, slippery saliva.

Once I judged the cock was wet enough, I let the harpy go, pressed its breasts together again, and slid myself back between them.

"Ugh…!"

My huge cock, glistening with saliva, glided back and forth through the valley of the harpy's pressed-together breasts.

Slick — slick — slick — slick—

Each time the soft breast flesh squeezed both sides of my shaft as it slid, a lewd, squelching sound rose from the wet saliva.

But just as the feeling of climax started to creep up on me, the saliva ran completely dry.

Harpy made no sound at all, merely staring down at the cock lodged between its own breasts.

What could this creature be thinking right now?

Did it understand what was being done to it?

I seized the harpy's hair from behind and forced its head up.

"…!"

Astonishingly, the harpy's face was flushed faintly red.

Don't tell me… it does understand?

"Ki… kiiii…"

The harpy let out a strange, feeble cry utterly unbecoming of its pretty face.

Come to think of it, at some point the fierce hostility I'd felt at the beginning was gone.

If the harpy understood even the slightest bit about the meaning of what I was doing, that only excited me more.

"I'm at my limit…"

My cock was so rigidly erect that the slightest touch felt like it would go off.

I needed to be inside something right now.

Her breasts weren't enough.

Then her mouth, as I'd thought before?

No — that was far too dangerous.

Getting carried out of the Hunter Management Agency with my cock chewed off after messing with a gate monster was the absolute worst-case scenario, and I wanted no part of it.

But I wanted inside her…! I wanted to thrust into her, hard and fast!

Then where the hell was I supposed to put it?!

Wait a second — this creature was a monster that looked like a bird fused with a human.

Every living creature had a hole down below, one way or another.

Even if her lower half was a bird's, there had to be somewhere to put it, right?

I immediately lifted the harpy's lower body.

Since it was currently fixed to the wall, the only way to see toward its rear was to fold the lower half upward like this.

"Oh-ho…"

And there, buried between the feathers, was a hole.

Birds, they say, use a single opening for laying eggs, for excreting, and for mating.

Because it combines every function into one organ, that opening in birds is called the cloaca.

And this beautiful harpy had one too.

A pink-hued cloaca.

But was it really okay to stick it in here…?

I hesitated for a moment — but by then I already had the harpy's lower body half-raised, and my cock was pressed against the entrance of the cloaca.

"Ki… kiiii! Kiiii!"

I spat into my palm and smeared it roughly over the glans and the cloaca's opening.

Then I pushed in slowly, and bit by bit, the head of my cock began to slip inside.

Harpy's eyes went wide with what looked like pain, and it thrashed wildly.

But with both wings locked fast to the wall, the harpy had no way to resist me at all.

"Nngh…!"

I could feel the harpy's cloaca clamping down hard around my cock.

There seemed to be a considerable amount of folds inside, because every movement sent an incredible wave of stimulation through me.

Could I even fit all the way in?

My cock is big.

I might well turn the harpy's insides into an absolute wreck.

But having already begun, there was no stopping now.

Just as it's hard to stop when you're close to the peak even in ordinary masturbation, I was already driving my cock forward on pure instinct.

"Kik! Kiiiik—!"

Harpy wailed, head thrown back.

And my cock sawed back and forth through the depths of the cloaca.

After repeating shallow little thrusts, I heaved my hips up with everything I had and buried my cock to the very root.

"Huaaaah—!"

A dizzying, electrifying pleasure flooded my skull to the brim.

It felt like current running up my spine.

I felt every moment of it — my semen blasting furiously down my urethra and erupting deep inside the harpy's body.

It was an enormous amount.

"Hnngh…"

Once that titanic wave of pleasure had passed, I carefully eased my cock out of the harpy.

The harpy's cloaca — which somehow seemed looser now than before — twitched, then heaved up a creamy flood of semen.

"Kiii…"

Harpy hung limp, every limb slack, head drooping, moaning softly.

And a moment later, a message appeared before my eyes.
