How Using My Oppai Skill to Enlarge My Sister’s Breasts Led to Building a Harem - Chapter 37

Chapter 37

<Rosecia’s Perspective>

Somewhere in the Waheide Republic.

A stunning young girl stepped onto a stage bathed in vibrant, multicolored lights.

Clad only in provocative lace lingerie, her most private parts were brazenly exposed. Her name… I don’t recall, but she’s supposedly a rising European actress.

The surrounding crowd erupted in deafening cheers.

Strutting around the circular stage, she flaunted her nearly naked body.

“Hmm, the turnout’s impressive,” I remarked.

“Yes, Your Majesty. With stricter laws in other nations, immigration inquiries to our country have surged,” my aide replied.

Humans crave freedom by nature. Laws may try to bind them, but the wealthy simply relocate. A safe, loosely regulated nation like ours, rich in entertainment, always draws crowds of hopeful immigrants.

“Shows like this are impossible elsewhere, aren’t they?”

As I chatted with my aide, the performance on stage progressed. The girl was joined by a young East Asian man, his erect penis plunging into her vagina.

(That man… a professional athlete from Japan, wasn’t he?)

The lewd sounds of flesh colliding, captured by stage mics, blared through massive speakers.

Paan♡ Pan♡ Pan♡ Pan♡ Pan♡ — Paan♡

“Oh♡ Oh♡ Oh♡ Ooh~~~♡”

“Haa… Haa… To fuck a woman this fine… Uoh!!”

The man, driven by lust, ejaculated, flooding her vagina.

Another wave of cheers roared.

“To think a mere sex show could whip them into such a frenzy…” I mused.

“But it fills the treasury, so it’s all to the good, isn’t it?” my aide said.

“Fufu, true enough.”

Laws stifle economies. They inflate production costs, spawn new agencies for corrupt officials, and breed decay. Overregulation inevitably topples nations—it’s obvious.

The trickiest part of democracy is that laws, once made, are rarely repealed. Lawmakers face little blame for creating them, but those who repeal them risk later scrutiny. So, laws pile up, and no one dares undo them.

This is why modern democracies are on a slow decline.

“The limits of democracy,” I said.

“Our nation, though democratic, retains strong royal influence,” my aide noted.

I don’t tolerate politicians pandering to loud fools for votes. Useless policies? I can force their repeal onto parliament’s agenda with a word.

Some call it authoritarian, but as long as the nation prospers, it’s no issue. This dual system—democracy tempered by royal power—prevents corruption and fuels our growth and independence.

“Still… it’s dull,” I sighed.

“Your Majesty, you’ve had proposals from numerous world leaders and dignitaries,” my aide ventured.

“Hah! Spare me. Those old geezers can barely get it up. They couldn’t handle my rejuvenated self.”

Even a former superpower president’s among them, but I’ve no interest.

“They’re free to lust after my beauty,” I said.

No man can resist me—none but one.

“Utterly boring,” I muttered.

“Not to your liking?” my aide asked, glancing at the stage.

I looked too. The man was now lifting the girl from behind, thrusting into her anus, treating her body like a toy as he slammed into her round rear.

Zubo♡ Guchu♡ Guchu♡ Guchu♡ — Dobyu♡

“Aa!! O~~~♡♡♡”

She climaxed, shrieking as he ejaculated into her anus. The crowd’s fervor peaked, applause and whistles unrelenting.

“Not enough. Such men can’t satisfy me,” I said.

Ordinary males no longer sate my womb. I crave a voracious, beastly man to devour me. My hand drifted to my abdomen, stroking the new life within.

“You understand, don’t you?”

“Yes,” my aide replied.

She, too, was ravished by that man, bearing his child.

“Enough. This place won’t fulfill me.”

“What shall we do, Your Majesty?”

“If he won’t come, I’ll go to him.”

“T-That’s… extreme.”

His homeland was Japan, wasn’t it?

“I’ll leave governance to my daughters. They’re ready to act in my stead.”

“Yes! I’ll issue directives and prepare a plane immediately.”

“Good.”

(A trip abroad after so long… I’m getting excited, despite my age.)

Thus, Queen Rosecia of Waheide set off for the Far East with her entourage.

※

June arrived, spring giving way to early summer, two months into the new school year.

“Senpai… Would you go out with me?”

Another girl confessed to me today.

“Sorry, I already have someone…”

“Oh… Sniff… Uu…”

Most confessions now come from first-years. By now, every second-year and above knows I’m taken.

I waited for the teary first-year to calm down, said goodbye, and headed back to class.

(Finally top of my grade… but it’s not enough.)

I aced the recent midterms, earning praise from everyone. But…

(My goal’s a top university, the highest-ranked faculty possible.)

Why the rush? Ayaka-san’s baby—my child—is due soon. Her due date’s early July, meaning she’s nearing the final month.

(She could deliver early. It could happen any day.)

Officially, our relationship and the baby’s paternity are secret; her current husband is listed as the father. Still, seeing her growing belly and radiant smile fills me with love.

“Gotta keep pushing…”

With renewed resolve, I threw myself into studying and training.

But I had no idea of the storm awaiting me.

…

“Darling! Hey, listen!!”

“Huh…? Oh, sorry…”

Today was a date at Satsuki-chan’s place, but I’d been lost in thought, earning a scolding.

(Is this relationship okay as it is?)

Satsuki-chan and I are officially together, deeply in love. That’s undeniable, but—

(I’m involved with so many women… And Ayaka-san…)

It’s harsh to admit, but lately, every spare moment is consumed with thoughts of Ayaka-san and our child.

(Is it fair to keep dating Satsuki-chan like this?)

I don’t want to break up. But staying together in this state—doesn’t that hurt her more? That’s what gnaws at me.

“Look, today’s cosplay sex outfit is… this!”

Two fluffy ears sprouted from her head—adorable cat ears.

“Cute?”

“Super cute! Like a real cat-eared beauty.”

Her silky blonde hair and perky cat ears were irresistible. Her flawless face amplified her charm.

(I can’t bear the thought of losing her…)

Shallow as it sounds, seeing this cat-eared goddess heated my groin instantly.

“You’re so cute, Satsuki-chan.”

“Ehehe, that makes me happy♪”

As I whispered, leaning closer, her perfect face flushed red.

“I can’t hold back anymore.”

“Come to me…♡”

She led me to her bedroom, her round hips swaying, stoking a primal urge deep in my core.

(I need to be inside her…!)

“Here, Darling, lie on the bed… An♪”

“Satsuki-chan…! Haa… Haa…!!”

Before she could turn, I pushed her onto the bed.

“I’m putting it in! Kuu…!”

“Aan♡ Geez, Darling…♡”

Lovers’ privilege—sex with unspoken consent. Our hearts are that close.

Paan♡ — Pachun♡ Pachun♡ Pachun♡ Pachun♡

“Ahaa♡ So good…♡ I love your cock, Darling♡”

“Satsuki-chan…! Your pussy’s perfect!!”

I went all out, pounding her from behind.

“I love you, Darling♡ Let’s be together forever♡”

“Satsuki-chan…”

Her hips wriggled lewdly, her pussy gripping me tight.

Pachun♡ Pachun♡ Pachun♡ — Kyuuu♡

“Kua…! I’m cumming!!”

“Aa♡ Aan♡ Let it out… Give me lots…♡”

“Aa!!!”

Overwhelmed by her pussy, I unleashed a torrent of semen from my tank.

“Naa♡ Amazing…♡ Aa… Aaa~~~♡♡♡”

“Satsuki-chan… I love you! I adore you…!”

Dochun!! Dochun♡ Dochun♡ Dochun♡ Dochun♡ — Byururu♡

“Hia♡ Aa♡ Aa♡ Cumming while thrusting…”

“Satsuki-chan… So cute… Aa!!”

It was perfection. She’s an unrivaled beauty—sexy, adorable, the ideal girlfriend. We slammed our hips together, cumming freely.

(We’re so compatible…)

Satsuki-chan’s a celebrity; every young person knows her. Her face, personality, body—everything’s my type, the perfect girl.

(But… I can’t abandon Ayaka-san…)

Ayaka-san was betrayed and hurt by a cruel man once. I could never do that to her. But marrying her means I can’t marry Satsuki-chan.

“U, aaa…!!”

Dochun♡ Dochun♡ Dochun♡ Dochun♡

“Hiii♡ Darling… Amazing~~~♡”

“Satsuki-chan…! Guu…!”

I don’t want to let her go—this adorable girl. Breaking up feels like my heart would shatter.

“Darling♡ Hug me tight…”

From doggy style, she turned to face me, gazing into my eyes in missionary.

“Satsuki… Chan…”

“Nn♪ I’m never leaving you, ever.”

Kyuuu♡ Her pussy clamped down.

“Agu! Feels so good…!”

“Haa… Haa…♡ Never, ever… I won’t let you go…”

“~~~! Satsuki-chan… Uu!!”

Semen spurted as if milked out.

“Because, in my belly…”

(What a beautiful face… She was gorgeous when we met, but now she might be Japan’s top beauty.)

“…There’s a baby.”

A baby.

It took a moment, but I realized she’s pregnant.

“T-That’s…”

“Your baby, Darling. Three months already.”

Three months… Too late for a simple abortion. Not that I’d want that, but…

“Three months…”

“It’d be tough to abort now…”

“No way I’d let that happen!”

It’s proof of our love. I’m grateful, not burdened.

“Can I keep it?”

“Of course! I’m thrilled…!”

“Aa… Haha… Thank goodness…”

Tearing up, she held her belly. She must’ve been anxious—my answer could’ve scarred her for life. Relieved it didn’t, I gently covered her, hugging her tight.

(Warm… Our baby’s in here…)

So precious. My love for her swelled, deeper than ever.

“Satsuki-chan… I love you. From the bottom of my heart.”

“Aa~~~♡ I’m so happy I could die…♡”

“Haha, don’t die.”

“Ehehe♪”

Forgetting our sex, we held each other, feeling our heartbeats. Pure happiness—not just physical, but a connection of souls. In that quiet moment, she spoke.

“Will you take responsibility…?”

My heart leapt, pounding so hard I could barely breathe.

“…”

“Darling…?”

Responsibility—marriage. We’re too young for legal vows, but it means living together as husband and wife.

I’d love that. A cute wife like her would make every day joyful.

But that would betray Ayaka-san.

In the end, I couldn’t answer Satsuki-chan that day.
