How Using My Oppai Skill to Enlarge My Sister’s Breasts Led to Building a Harem - Chapter 30

Chapter 30

Rewinding time a bit.

Threatened by a woman claiming to be the queen’s envoy, I’m brought to the island’s central district.

“Get out.”

“Y-Yes.”

Tumbling out of the luxurious car, I’m stunned by the massive structure before me.

(I heard this was a wealthy nation… but this is unreal.)

A dazzling, golden palace, as if built for divinely chosen humans.

“Hmph, country bumpkin. Stop gawking and walk.”

“Yes…”

I’m led between rows of women who seem to be servants.

Behind me follows the green-haired officer who fetched me—a stunning beauty with a sword, moving with flawless precision, showing no openings.

(Escape’s impossible…)

I’m not restrained, but that’s because there’s no need. If I tried to flee, I’d be swiftly subdued, possibly sliced. Gripped by fear, I step into the radiant palace.

“Stop.”

“…”

“Strip. Everything.”

Multiple female officers strip off my shirt, pants, and underwear, ushering me into a steamy room.

“Ugh, hot… A sauna? No, a steam bath?”

To avoid angering them, I endure silently. After a while, drenched in sweat and near collapse—

“Alright, out.”

“Haa… Haa… Uwah!”

Cold water douses me from above.

“Open your mouth.”

As the green-haired officer orders, I comply, and she inspects every corner of my mouth.

“Good. Raise your hands high.”

They check my hair, armpits, groin, even my urethra for hidden objects.

“Now, come here and get on all fours.”

I obey, kneeling on the stone floor like a dog.

“Don’t move.”

“Gu… Ugh…!”

Something’s inserted into my anus—likely—

“Hmm, no weapons.”

“Gua… Uuu…”

It was the officer’s finger.

Checking for concealed weapons, she twists her finger inside me.

“S-Stop… please…”

“Hmph.”

Zubo! The finger is yanked out.

“No issues. Take him.”

Reeling from the violation, I’m hauled by new officers to another room.

(What’s happening… Why me…?)

Dazed, I’m taken to a tidy room and dressed in pristine traditional attire.

“This is…”

“Our country’s traditional clothing,” a servant explains.

“I see.”

“You must be properly dressed before Her Majesty.”

These servants are unarmed, likely untrained in combat—ordinary maids.

(Escape…? No, that woman’s probably outside.)

Even if I reached the exit, I couldn’t outrun them on foot. I’d be caught and punished. Resigned, I let them dress me and spritz me with perfume-like liquid.

…

“This is the audience chamber. No funny business.”

“Y-Yes…”

As if I could. Armed female soldiers glare at me.

“Enter.”

I step into the audience chamber. At the center, a soldier speaks.

“Stop. Kneel and bow your head.”

I obey, dropping to one knee, face to the ground. I’m unsure if this is proper etiquette here, but it seems fine.

(I recall Ayaka-san’s etiquette lessons… Don’t raise your head until permitted by someone important.)

Remembering her teachings, I stay still.

Clack clack. Footsteps approach from ahead, stopping at the center. Silk rustles as someone sits.

“Raise your face.”

A woman’s voice, low and dignified, carries the authority of an absolute ruler.

(Some cultures see raising your head at the first call as disrespectful, but ignoring a king’s command could be worse…)

“Hah!”

I lift my face. On a golden throne sits a striking woman with dark skin.

“Well met, traveler from afar. I welcome you.”

(This is Her Majesty… Beautiful…)

Her name, I believe, is Rosecia, but calling her by name might be disrespectful.

“Hah! I’m deeply honored to be granted an audience with Your Majesty…”

“Fufu, no need to be so tense. This is a personal matter. Speak normally.”

“…Yes. Then, why was I brought here?”

The surrounding soldiers stir, casting sharp glares.

“Enough. This man is my guest,” the queen silences them. “Your question…”

Her gaze sharpens.

“I heard you’re a renowned masseur in your homeland.”

“Uh… I did massages, but renowned is a stretch…”

“No need for modesty. Don’t underestimate our intelligence network.”

Her piercing eyes pin me.

“Y-Yes. I’m not sure about fame, but I’m confident in my skills.”

“Good. Then use those hands to massage me.”

Without hesitation, she removes the cloth covering her breasts.

“I’ll judge if your power is real,” she says with a sly grin.

※

Leaving the audience chamber, I’m exhausted and nearly collapse.

“Hey, you. Harm a hair on Her Majesty’s body, and your life is forfeit.”

“…Gulp. Understood…”

Threatened again by the green-haired officer, fear grips me.

(I don’t even want to do this… But refusing might cost my life.)

Her tone suggests she knows about my special ability. I didn’t deny it then, but if she demands something beyond my power and I fail, who knows what’ll happen?

“If you need anything, tell the servants now. You’ll be called when Her Majesty is ready.”

“Yes… Massage oil, please. If none’s available, pao fruit oil will do.”

“What… Pao fruit?”

Is something wrong? Pao fruit is a local specialty; edible oil should be accessible.

“…Fine. Get him what he asked for.”

“Yes, Lady Leonora.”

So, her name’s Leonora. Judging by the servants’ deference, she’s high-ranking.

I’m taken to a servant’s room, changing from audience attire to a minimal loincloth for laborers—likely to prevent weapon smuggling.

(The female servants were dressed similarly.)

Unlike Leonora, they wear no metal ornaments—just simple cloth over hips and breasts.

The oil’s ready by the time I finish changing.

(Hmm. Pao oil’s impressive…)

High viscosity at room temperature, it glides perfectly when warmed, as I’ve used on Maya and Carla. Its fragrance and skin benefits are exceptional, likely suiting locals best.

“Hey, Her Majesty’s ready. Move.”

“Y-Yes!”

Led by Leonora, I head deeper into the palace, servants carrying oil and cloths.

“This is the room. Don’t do anything unnecessary.”

She knocks, waits for a response, and opens the door.

“Excuse me.”

I bow to Leonora and enter the dimly lit room where the queen awaits.

…

“Well met. I’m eager for your massage.”

“Hah, I’ll do my utmost, however humble my skills.”

She’s the nation’s pinnacle. She seems kind now, but one misstep could cost me my head.

I choose my words carefully, preparing for the massage.

“Is pao fruit oil acceptable?”

“…Interesting. I’ll leave it to you.”

“Yes. And—what kind of massage do you desire?”

That’s the crux. Is it for illness or beauty? The approach differs.

“Hmm. I heard you heal by massaging breasts.”

“Yes, that’s correct.”

“Then… you should discern what’s wrong with my body, no?”

“Uh…”

Her testing words freeze me.

“Was your confidence a lie?”

“N-No, it’s not…”

Of course. If she’s challenging me, I have my pride.

“Then begin.”

“Yes, excuse me.”

She nods, and I remove the thin cloth over her chest, exposing her breasts.

(What an incredible body…)

Her physique is toned, sculpted like a statue. Entranced, I drizzle pao oil into her cleavage.

“Pardon me…”

Gunyu♡ Gunyuu♡

(What’s this breast pressure!?)

Unlike any I’ve touched, her breasts have overwhelming firmness.

I glance at her face, but she smirks faintly, unbothered by a mere mortal like me touching her.

“What of my breasts?”

“They’re… magnificent.”

I forgot my task for a moment.

But I can’t continue like this.

Gu… Guu♡

I grip her breasts again, probing for ailments.

Mugyu♡ Muni muni♡ Gyuuu♡

(??? …Nothing’s wrong…)

“What’s the matter? Can you tell anything?”

“…Your body has no abnormalities.”

“Hmm. Any quack could say that.”

She’s right. I must voice what I’ve learned.

“May I, with all due respect, state my findings?”

“Permitted.”

Taking a breath, I speak.

“You’re around forty, have given birth multiple times, and fractured your right leg in the past.”

“Hmm.”

“As for skeletal alignment—”

I describe her spine’s curve and pelvic position, deducing her sleeping posture.

“Impressive, you can tell that much…”

“Yes.”

“But you haven’t found what I want healed.”

What? Not illness or injury. Beauty, then…?

“…I’m sorry, I can’t think of anything.”

I can’t fathom it. She’s healthier and more beautiful than most at forty. What could she be dissatisfied with?

“Then I’ll tell you.”

Her words pique my curiosity—what can’t my ability detect?

“It’s aging.”

“…What?”

“Aging. Remove the scourge of senescence from my body.”

That’s absurd. I nearly say it but stop.

Her gaze is deadly serious. A careless word could mean my death.

“Can’t you do it?”

“I… don’t know.”

“Do it. Fulfill my wish, and I’ll grant you any reward.”

“Yes… I’ll do my best.”

I couldn’t refuse.

※

Now, confined in a room, I wrestle with her impossible demand: eliminating aging.

(Aging’s a natural phenomenon… Some say it’s God’s decree.)

I’m no expert on aging. From healing Nozomi’s eyes, I learned I need knowledge to use my power effectively.

“First, I need knowledge about aging.”

Thus, I tackle aging, once deemed an inescapable fate ordained by gods.

…

Though confined, I’m permitted to gather information.

“Aging involves telomere shortening and senescent cell accumulation…”

Cells can make errors during division, causing cancer.

“To prevent this, cell division is limited to avoid propagating faulty cells.”

Telomeres, like a “life ticket,” shorten with each division. An enzyme to extend them exists, but using it risks unchecked cell growth, leading to cancer and shorter lifespans. Telomeres are a safety mechanism against cancer.

“And senescent cells…”

When telomeres shorten too much, cells stop dividing, harming nearby cells and increasing errors.

To rejuvenate:

1. Remove senescent cells.
2. Eliminate pre-cancerous abnormal cells.
3. Extend telomeres.

Theoretically, removing aged cells, preserving healthy ones, and increasing divisions could reverse aging.

(Can I do this…?)

Understanding aging shows it’s not divine but a bodily defense mechanism.

It’s not impossible.

Some organisms don’t age. Overcoming human aging isn’t blasphemy—it’s science.
