Chapter 1: Welcome to the Interspecies Fertility Clinic!

Interspecies.

The otherworldly beings that had appeared on Earth a hundred years ago.

"Mister Orc! What do you think you're doing, hanging the signboard upside down?!"

"Grruk... s-sorry..."

But humanity scorned and discriminated against these uninvited guests... and the resentment they had suppressed for so long finally erupted into the catastrophe known as the Species War.

"Forget it. Let's just go grab something to eat. Do you like jajangmyeon?"

"Grrukk... I do."

Of course, not every human turned their nose up at the other races.

Those who realized that hearts could connect even when faces could not joined hands and formed an alliance instead.

And so the world split into the Human Supremacist Faction and the Race Syndicalist Faction, waging a long and bitter war against each other...

"Kobold bros! What are we putting on the menu?"

"Kkanpung shrimp is bullshit—go crunch your own dicks in garlic instead. It's jajangmyeon or nothing. Unanimous."

Finally, ten years ago, a peace treaty was signed, and a period was put at the end of the species conflict for good.

"Finally... a place to call my own."

"Hero. Is opening a hole-in-the-wall shop truly all you wished for?"

"Hole-in-the-wall, you say? This, Your Majesty, is the next big thing in business, I'll have you know!"

"...And what, pray tell, is the meaning of this outlandish signboard?"

"Empress, you shouldn't say such dangerous things! We live in an era where humans and the other races marry each other—a place like this is practically a public necessity!"

Once the war ended, the human–interspecies alliance had promised to grant me any wish I desired in return for my service.

So in exchange for living out my days quietly, I'd asked for a plot of land in the heart of Seoul and enough money to set up a shop.

"Surely you would have fared better betrothed to Us than to this..."

The woman rattling off her complaints beside me, while I fussed over my grand opening, was none other than the head of the Allied Forces.

The Empress, Rosalina Pelgrant.

My patron since the days ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠before I had a name to speak of, and my liege—to whom I had devoted half my life in service.

"Dunno. Seems like a step up from being kept by an old maid."

"Urk?! I have merely neglected myself for the sake of peace, that is all!"

Objectively speaking, she was a beautiful woman.

Luminous platinum-blonde hair, glamorous lashes, and elegant features that carried an utterly captivating charm...

Her breasts and hips, enormous enough to rival her flowing hair, might have tipped into vulgarity on anyone else—but the poise she carried transformed them into the very image of a goddess of fertility.

"Even so, you're still an old lady."

"This One is still in her early thirties! Have you never heard the phrase 'aged like fine wine'?!"

But me? I'd take a young, fresh woman over wine any day.

Thwack! Thwack!

"Aagh! It hurts!!!"

"You wretched man. Leaving me behind like this..."

"Hold on... why are you crying again?"

At some point the Empress's eyes had gone glassy with tears, and she muttered, visibly upset.

"Without you, I feel hollow inside. You are the only loyal vassal I could ever entrust everything to, Frey..."

"..."

Still—spinster past her prime ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠or not, a woman's tears never failed to soften me up.

"Hoh hoh... no, never mind. I was being far too stubborn. You have a life of your own to live, after all."

She forced down her tears and managed a tender smile.

"Be happy, Hero Frey. Though we part like this, I shall never forget the loyalty you devoted to me—"

"Rosalina."

"...Yes?"

But this wasn't the ending I had in mind.

I swept her into my arms!

"Kyah?! What on earth are you—"

"Maybe you've gotten so old your mind's slipping..."

I wrapped my arms tight around her slender waist and breathed the words against her reddening ear, savoring every syllable.

"Make that bitch-in-heat face and even I can't hold back. I'll devour you whole when I find the time later—so keep that pussy wet and wait for me."

"Ah... ahh... oooh..."

"No answer? Or would you rather I stretch that pussy loose with my XXL cock until you're popping out babies three seconds after I finish?"

"Hyiii..."

The woman in my arms shuddered at every word, spilling out broken, undone little sounds.

Her plump, squishy belly pressed flush against me and quivered—and my enormous package began to swell in response.

"Feel that?"

"Th...this absurd, brute size..."

"Someday I'm going to bore straight through your cervix like an interstate highway. Be ready for it."

"Yesh...♡"

By then her lower belly was pinned flat against the cock straining up through my pants, and Rosalina exhaled weakly, her face utterly melted.

A slow trickle ran down her thighs—naturally, her golden dress was already soaked clean through with her love juices.

Smack!

"Off you go, then."

"Y...you absolute pervert..."

I gave her ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠ass a parting slap in place of a farewell, and she shot me an adorable glare with a face burning red before finally taking her leave.

Really, she was a cute woman, no matter when you looked at her.

"Now then—time to actually get this business rolling?"

Anyway, with the Empress sent back to the Imperial Palace, I wrapped up the last of my preparations and opened for business.

Air conditioning: installed!

Lighting and furniture: installed!

Peak condition, ready to welcome a customer the second one walked through the door.

"Cha-ching, baby! Let's gooooooo!!!"

No more fighting—this was the era of a hero cashing in and sweeping up the dough!

. . .

"Customers...? ...None?"

But contrary to my rosy imaginings, more than a week passed with nothing to show for it but gathering dust.

I tried everything to get the word out—posting on the Interspecies Gallery, hustling for virality—but all that came back was indifference.

"This isn't how it was supposed to go! They said we'd moved past international marriage into the age of interspecies marriage!"

Damn media hacks.

I'd read one article, decided this was the market's ground floor, and jumped in—and the whole thing turned out to be pure scam bait.

In reality, actual marriages between humans and the other races numbered precious few.

For interspecies and humans to bear the fruits of love together, there were still hurdles waiting to be cleared—culture, appearance, body structure, and so on.

Frey. Twenty-nine. Retired Hero.

Life utterly fucked by one unsourced scam article.

Ba-dum tss.

"If I'd known it'd come to this, I should've just married the Empress and lived as a kept man."

I collapsed limply over my desk, motivation gone.

I'd have to pay taxes eventually. What was I going to do?

At this rate, money would keep draining out—rent, license fees, the works—until I went under completely.

Whooooosh.

"Why is it so cold in here, though? I set the AC to 26 degrees."

But a chill had been creeping in for a while now, and my breath was misting with every exhale.

Beep beep!

"Argh! I turned it off already—why is it still cold!"

And so, mid-wrestle with the air conditioner remote...

Jingle!

"Is this the Interspecies Fertility Clinic?"

"C...come in!"

A woman stepped into the shop.

Where Rosalina was flamboyance itself, this one had the quiet, refined grace of a well-bred young lady.

Silver hair cascading all the way down to her ankles caught the light like snow crystals, and her lashes and irises were tinged the same mystical silver-white.

Wrapped chastely in a traditional Japanese kimono, she came toward me at an unhurried pace, wooden geta clacking softly on the floor.

"I would like to have a consultation about infertility."

"Ah... yes, please have a seat here."

She settled into the chair across from me, and a wave of cool air rolled over the desk.

Thank goodness I was a retired Hero—any ordinary human would have been half-frozen solid by now.

"May I have your species and name?"

"I am a Yuki-onna. My name is Yuki."

"Miss Yuki, let me run through a few basics. Any chronic conditions you're currently aware of? Any history of surgery?"

"None."

"Then, regarding the frequency and timing of you and your husband's relations—"

"There is none."

"Ah... you don't have intercourse at all?"

"There is no species that could take me as a partner in the first place."

"..."

Right.

Of course—if she went around radiating cold like that, even a perfectly healthy man would freeze solid mid-thrust like some frozen dildo.

"There are only a precious few of my kind to begin with, and we are all born female—so our numbers dwindle a little more with each passing year."

"I see."

"At this rate, my clan will fall to ruin. Please, I beg you—help me."

"Um... help you how, exactly...?"

What was I supposed to do about there being no compatible mate on the planet?

Tear open a portal to another world and drag in a frost giant from Jotunheim?

"You there—I do not know what you are, but I can sense a powerful aura about you."

"Sorry?"

"Someone like you could shrug off a Yuki-onna's chill without the slightest effort..."

With a soft rustle—

she loosened her demure sleeve and whispered in a voice gone wet with want.

"Please... let me carry your seed..."

"What."

Hold on—doesn't this make my clinic less of a fertility clinic and more of an outright brothel...?

Whoosh!

"This is the village where we Yuki-onna make our home. It is beautiful, is it not?"

"It's gorgeous, but man, is it cold..."

Guided by the Yuki-onna Yuki, I had arrived at a remote mountain valley deep in the Japanese countryside.

Standing before the gates of a vast estate in the Snow Woman Village, where the snow never stopped falling in any season, Yuki and I waited side by side.

Creeeak.

"Welcome home, my lady."

A mature, seasoned Yuki-onna opened the gates and bowed to receive us with perfect courtesy.

"Your patient seems to be someone quite high-ranking?"

"Yes. My mother gathered the Yuki-onna who migrated to Earth and has carried our clan through these chaotic times as its Matriarch."

To put it simply, Yuki was something like the princess of the Yuki-onna.

A species with no heirs faced a fatal problem—no wonder she'd taken it upon herself to come see me personally.

"While we were desperately searching for a way to solve our succession crisis, we found your clinic."

"I'm all the way over on the Korean Peninsula. How did you find me?"

"We searched for you on Zoogling."

The village looked plucked straight out of the Edo period, and yet—pretty tech-savvy bunch, huh.

Crunch, crunch.

By the time Yuki and I had chattered our way across the snow-covered garden...

"Yuki? You have returned at last."

"Yes, Mother."

A soft, silken voice rang out across the garden as a woman appeared.

A blue robe that barely contained her ample bust. Long, sweeping lashes.

Her ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠hair, demurely gathered into a low side-tail, radiated the smoldering allure of an older woman in her prime.

"And the gentleman standing there would be...?"

"Ah—hello there! Frey, infertility specialist, at your service!"

"Fufu. Welcome. I am Yukina, the Matriarch of the Yuki-onna."

Yuki's mother, every inch the mature and gentle hostess, offered her hand with the faintest of smiles...

Squeeze.

"Oh my... what a manly, sturdy hand you have...♡"

"..."

She toyed with my palm, a sensual little giggle spilling from her lips.

Th...this is strictly business. Nothing more.

A doctor must never, ever develop personal feelings for a patient or her family.

'So calm the hell down already, my friend...!'

With superhuman strength of will, I pinned down my lower half before it could get any ideas about the lascivious MILF standing before me.
