How Using My Oppai Skill to Enlarge My Sister’s Breasts Led to Building a Harem - Chapter 31
Chapter 31
<Rosecia’s Perspective>
“That man… to think he noticed the properties of pao fruit…”
“Could there have been a leak, Your Majesty?”
Queen Rosecia of Waheide smirks, soaking in a sweet, syrupy liquid.
“No. Pao fruit is strictly controlled, never leaving this country.”
“Indeed, Your Majesty.”
For at least 3,000 years, according to records, pao fruit has been used for a specific purpose, kept secret from outsiders.
“Only I can use it in such quantities daily.”
“Truly, Your Majesty is radiant today.”
“Hmm. But while outward beauty is maintained… the inside…”
Rosecia strokes her lower abdomen.
“Ten years ago, my body would burn with desire…”
“Pao extract is also a potent aphrodisiac.”
That’s its second effect. By concentrating and selling it to the world’s elite, Waheide has amassed its wealth.
“If that man truly possesses divine power…”
A chuckle escapes her, words drowned by laughter.
※
Threatened by Her Majesty, I’m tasked with stopping aging, massaging her breasts daily.
Guni♡ Guni♡ Gunyun♡
“Fu… Nn…”
My ten fingers knead her dark breasts. Their pressure is intense, like water-filled balloons.
“Will this truly rejuvenate me? You’re not just fondling, are you?”
“No, Your Majesty…”
My life’s on the line, so I’m desperate. But rejuvenation is vague, hard to visualize.
(First, remove senescent cells.)
Vague imagery won’t do. I’ve massaged hundreds of women, young and old, my hands memorizing every sensation.
(Visualize… cells abundant in the elderly, scarce in the young…)
Clearing my mind, I focus all consciousness on my hands’ nerves. Sweat beads on my palms, seeping into her skin.
Gu… Gunyuu♡♡♡
“Hoh… Interesting.”
Her tone shifts. Her face flushes, body temperature rising.
I’m stimulating her immune system to eliminate old cells.
(It’s working… Elevated temperature signals an immune response. Next…)
“Ku… Mmm…”
“Are you alright?”
“Haa… Haa… This is quite effective.”
The second step—removing abnormal cells—is part of immunity but taxing when done simultaneously.
“Let’s continue tomorrow. Overstraining your body would defeat the purpose.”
“Hmm. As you say.”
Thus, I visit her room daily to rejuvenate her.
…
A week passes.
Gunyuuu♡ Gu gu… Gunyun♡
“Nn… Haa♡ Good. My body feels lighter each day…”
My massage reaches the final stage: secreting telomerase to accelerate cell division, spreading it through breast massage.
“Oh…♡ Vitality… surging within…”
“Yes. Your body has rejuvenated to your late twenties.”
“Oh… What incredible power.”
Pushing to twenty might be fun. I speed up my fingers.
“Nhaa…♡ My body… transforming…”
“Your Majesty…”
Her body glows more beautifully, her face regaining youthful softness. The once-dignified queen now wears a gentle, girlish smile.
“C-Cute… Ah…”
“Kuhahaha!!!”
“Sorry…”
“No matter. When was I last called cute…? Fufu.”
I’m lucky. Calling a monarch cute could be disrespectful, but her good mood saves me. I must be careful.
Munyun♡ Munyumunyu♡ Gyuu♡
“Kufufu…♡ Fuu… Fuu…♡ Irresistible, this youth… My body’s ablaze.”
“Now for a stronger finish.”
“…Noh♡”
I grip her breasts hard, fingers sinking in, vibrating like a machine.
“Kuohhh♡ It’s… intense…♡”
Her body quakes. A muwari♡ burst of aroused pheromones fills my nose.
“Oh, oohhh♡ My womb… stirring…♡”
Her rejuvenated body reactivates her reproductive functions, her abdomen trembling.
“Haa… Haa… Nfu, hahahaha! HAHAHA!!”
“Your Majesty…?”
Her crazed laughter unnerves me. I speak cautiously. Her eyes lock onto me.
“Hey, you. Show me your cock…”
“Huh?”
“Shut up and show it!”
“Uwah!?”
The queen, unhinged, bellows. Her voice carries outside—
“What’s wrong, Your Majesty!?”
Female soldiers burst in.
“Restrain him!”
“Yes! Stay still, scum!!”
“Gwah… No, I didn’t…”
Before I can flee, my arms are pinned, and I’m shackled to the floor.
“Good. Tie him to the bed.”
“Huh…? Yes!!”
I’m bound to the bed, limbs immobilized.
“Fufu, nice pose, huh? Jururu…”
“W-What are you doing…!?”
“What? When a man and woman meet, it’s sex, obviously.”
Her face is pure lust, tongue licking as she plans to ravage me. She tears off my loincloth.
“Come on, get hard!”
“Tch, that’s not how it works…”
Bound like this, with scary soldiers glaring, I’m not bold enough to get erect.
“Hmm, fine. Bring that.”
“Yes!”
She orders a subordinate to fetch a vial of liquid.
“Drink.”
“Ngu…! S-Stop…”
The syrupy liquid, with a familiar sweet scent, is forced into my mouth.
“Nn! Gokku… Gokku…”
“Kukuku…”
(What is this… Sweet like honey, almost…)
“It’s concentrated pao fruit juice.”
“Puh! …What?”
I realize—it’s the scent of pao fruit, harvested daily and served at Maya’s.
“This is our sacred treasure, prized as a tonic since ancient times.”
“…”
“In small doses, it’s healthy. But in large amounts…”
“Gu… U…!!!”
My stomach burns like fire, the heat sinking lower—
“Uaaaah…!”
My groin swells, my cock painfully erect.
“Kuhahaha… Yes, in excess, it’s a powerful aphrodisiac.”
“Aa… Aaa…”
As she says, my cock balloons, veins bulging, glans throbbing with overstimulation.
“What’s… this…”
My balls swell too, pumped with too much blood.
“Look, your balls are huge. Here!”
“Aga!?”
She grabs and kneads them roughly.
“But cumming too soon ruins the fun.”
“Ugh…!?”
She ties my cock’s base with a leather strap.
“Now, time to feast on a male… Kuhaha!”
“S-Stop…! —Gu… Uuu!!!”
Straddling me, she aligns her dripping pussy with my cock and slams down.
Zu, chun…♡
“Aa! My cock…!!”
“Nohh♡ So thick…♡ A strong male, after so long♡”
Bachun♡ Bachun♡ Bachun♡ Bachun♡
Her glistening dark body bounces wildly atop my bound form.
“Oh, hot…♡ My womb craves a male…”
“Hii, aga…”
“Here!♡ Here, here♡ How’s my pussy…♡”
Dochun♡ Dochun♡ Dochun♡
“Aaa!! I’m cumming… It’s coming!!”
The pleasure drives my cock to ejaculate, but— “Igiii!! It hurts…!”—the strap blocks it.
“Aa! Aaa!! My cock’s breaking!!”
“Kuhaha! Entertain me more!”
She doesn’t care about me, using me solely for her desires.
(At this rate, I’ll really break…)
Feeling danger, I resist the pain, fighting back.
“Aa! Aaa! Gua!!”
Paan!! — Paan! Paan! Paan! Paan!!
“Ooh♡ Good! Keep thrusting into my pussy!!”
“Igii!! Oaa!! Guoo!!!”
Pain and pleasure turn my vision red, hips thrusting frantically. Endorphins flood my brain, eyes gleaming.
“Yes♡ That face…♡ A male desperate to ravage me♡♡♡”
In her youth, Rosecia, a peerless beauty, was courted globally. Though calmer with age, her core nature persists.
“All men in this world are mine! Here♡ Here…♡ How is it…♡”
Zu, nuchun♡ — Paan! Paan! Paan! Paan!
Unable to stay rational, my muddled mind drives my hips relentlessly.
“Haha! Good, good♪ It’s rising after so long…♡”
“Haa! Haa! Aaa!!!”
“Your cock and balls are swollen, ready to burst♡ Kuku… Time to—”
Her face shifts to a beautiful, terrifying smile.
“—taste heavenly pleasure.”
She snaps off the strap.
Instantly, unimaginable pleasure surges through me.
“OAAAAHH!!”
My engorged balls unleash an unbelievable torrent of semen.
Roaring like a beast, I cling to consciousness amid the ecstasy.
“Nohh♡ Incredible seed…♡ More, give me more♡♡♡”
It won’t stop. Dobyu! Byu!! Yogurt-thick semen pours out, her amused eyes watching like it’s a toy.
“Ooh…♡ Fulfilled… My womb is filled♡”
“A… Gu… Aaa…”
Brain-breaking pleasure—a true celestial climax.
“Kuhahaha! I like you… Become mine.”
“A… A…”
“Be mine, and taste paradise daily.”
No way. This sex would kill me daily. Sensing mortal danger, I hold onto consciousness.
“I… refuse…”
“…What?”
A chilling, terrifying voice.
“I… have a place to return to.”
“Hmm. That’s irrelevant to me.”
“That’s…”
Unfair. Her selfish disregard for my will.
“If you take that attitude, I have my ways. Bring it.”
“Yes!”
“W-What…”
She orders a servant, who returns with something that pales my face.
(A syringe… No way?)
“Don’t move, or I’ll miss.”
“Ugh…!”
Bound, I feel a needle pierce my thigh, injecting liquid.
“Kukuku… This is pao concentrate, further refined.”
“What…”
“Injected into your veins… Ohh♡”
My cock inflates, muscles bulging, the liquid rushing to my brain—
“GUOOO!!!”
“You lose reason, becoming a beast♡”
My body is hijacked by animal instincts.
※
Bachun! …Pachun♡ Pachun♡ Pachun♡ Pachun♡
“Oh♡ Ooh♡ Stop… Aa♡”
My restraints are gone, but my body won’t obey, thrusting into the woman before me.
“Haa! Haa! Haa! …Aaa!!!”
Dopu♡ Semen floods her pussy.
(What… is this? What’s happened to me?)
Conscious but uncontrollable, I can’t speak.
“Kuhahaha! Good, ravage more. Etch pleasure into her body!”
The queen’s voice. I piece together the scene.
Women. Women, women, women—covered in white fluid, collapsed.
“OAA!!!”
Dobyu♡ More semen spurts from my cock.
“Uhh♡ Aaaa~~~♡♡♡”
Another falls, convulsing in pleasure, clad in exotic attire.
“Kuku♪ Next—”
(Is this… me? Doing this to all of them…?)
Beautiful women sprawl on the bed, semen dripping from their thighs—apparently my doing. Terror grips me, but my body trembles with joy.
“The last… Leonora.”
“Your Majesty…! Must I face him too!?”
“Of course. Do you defy me?”
“N-No…”
After violating countless women, I’ve given up. I might be trapped in this lust forever, never regaining sanity.
Then, the final woman called is Leonora, who brought me here.
<Leonora’s Perspective>
Me, Leonora, having sex with this savage foreigner? Unthinkable. Born to Waheide nobility, gifted in martial arts, I’m an elite high officer.
Yet—
“Do you defy me?”
The absolute queen’s decree sentences my chastity.
“GUOOO!!!”
The man—no, beast—grabs my arms, pinning me to the bed.
(Such strength! Damn, if I had my sword… No, weapons aren’t allowed in Her Majesty’s chamber.)
Outmatched in raw power, my loincloth is torn off.
(My first time, like this…?)
His massive, stake-like cock brushes my privates.
Suru
The last cloth falls, exposing my pussy.
“Uuu… OOHH!!!”
“Stop…!!”
His cock presses closer. A few centimeters more, and my purity will be shattered.
His hands grip my hips, tensing.
“H-Help… No!!”
A pathetic plea escapes me. I can’t help it—this huge cock tearing my hymen is terrifying.
But my plea goes unheard—
“GRUAAA!!!”
“HIGIII!!!”
My hymen is ripped apart by this nameless foreigner’s cock.
“Oh! …Oohhh♡ Hiii…♡ Hiii♡”
I came. My hymen brutally torn, I came.
“Why…♡ My body… moving on its own♡”
“OAA! AA! AAA!!!”
Dochun!! Dochun♡ Dochun♡ Dochun♡ Dochun♡
My womanhood is ravaged by his cock.
“Ngii♡ Feels good…♡ Aga♡”
Impossible. Cumming during my first time, losing my virginity…
“Kukuku…! Incredible, your divine hand…”
Her Majesty says something, but I’m too overwhelmed to comprehend.
Dochun♡ Dochun♡ Dochun♡ Dochun♡ — Dochun!!
“AOHH♡ Hii… Hiii♡ OGOHH♡♡♡”
Pounded from behind, I climax repeatedly.
(My… body… submitting to this male…?)
Continuous orgasms, trembling in ecstasy, my voice seducing him.
I’m dominated beyond return. But I mustn’t cross one final line. With my last strength, I beg the beast ravaging me.
“Aa! P-Please… Don’t cum inside…!”
“Uuu… OOHH!!!”
Dochuu! Dochuu! Dochuu! — Dochun!
“No! Stop…♡ Aaaa~~~♡♡♡”
Warm fluid blasts my depths, clinging to my womb, seeking to impregnate me.
Dobyu♡ Dobyu♡ Dobyu♡ Dobyu♡ Dobyu♡
“Aa♡ Aa♡ Naaa~~~♡♡♡”
I came. Seeded by him, I came.
So good. So good. So good.
Ravaged, impregnated, and broken by a stranger I barely know.
“More♡ Ravage me… completely♡”
“U! …UGAAA!!!”
Ravaged.
Body and soul.
Broken.
Status, pride—gone.
My old self vanishes, reborn anew.
“Ahaa♡ So… happy…♡”
With those words, my eyes roll back, and I collapse onto the bed.
※
Leonora writhes under my cock.
Dochuu! Dochuu! Dochuu!
I thrust violently, venting my anger at their abuse.
(Break… Go mad on my cock…)
Dark desires consume me.
“Kuhahaha! Yes, unleash your desires—your true nature!”
“UAAA…!”
Overwhelming pleasure and omnipotence.
After tasting this, I can’t return to my old self.
“Swear loyalty to me, and I’ll let you have women anytime, anywhere.”
“AAA…!”
Perfect. Obey her, and I can have women endlessly. No reason to refuse.
I step into a black swamp of desire.
“Want virgins daily?”
Virgins.
Defiling innocents every day—watching them cry or plunging them into pleasure with my hands. Either way, thrilling.
The black swamp reaches my waist.
“I’ll give you pao elixir. Go mad or drive women mad♪”
That drug erases pain and sorrow, letting me indulge in pure desire—a magic potion.
The dark water climbs to my chest.
“No better deal exists in this world.”
True. My old world was restrictive—laws, scrutiny, parents. Did I ever do what I wanted?
The women I loved didn’t need me.
Faces of women from Japan flash in my mind.
Satsuki-chan.
Golden short hair, my first girlfriend.
Yukino.
Glossy black hair, a friend who became my second girlfriend.
Nao.
Peach-haired girl, clingy and dear like a sister.
Riria.
Once a player, she strove to earn my approval after we slept together.
All beauties men would chase if free.
Miyabi-san.
The cool woman I admire. I never won her heart, but countless men desire her.
And Ai.
My sister, my greatest love, who accepted our forbidden bond.
But… Ai doesn’t need me.
She could marry normally, build a typical family—perhaps her best future.
The black water reaches my chin.
Without me, no one suffers.
Resignation engulfs me.
“Become mine.”
The queen’s words.
I should accept. A utopia where I’m needed, with heavenly pleasure—now, I—
…
…
Wait.
There’s one more… someone precious.
Yes—Ayaka-san.
Her face at our parting replays.
Anxious, lonely, yet hiding it, gently stroking her belly.
My child.
Yes, her womb carries my child…
Another image plays.
“Come back soon… darling…”
I don’t know that expression.
Her belly’s larger than when we parted.
This… must be my imagination.
But she was crying.
Ayaka-san was crying.
The black water vanishes.
※
<Rosecia’s Perspective>
“Become mine.”
The final push.
No one resists pao elixir’s madness.
This is confirmation—my victory declaration.
Silence.
Did I overdo it, breaking his mind?
“I refuse…”
“What?”
“I refuse. I’m returning to Japan.”
Speechless.
He regained sanity, defying my command.
“Don’t jest… Why… No, this is my order!”
“I’m not of this country. I have no duty to obey.”
I’m flustered, words failing me.
“Who… are you…?”
“…? I’m just an ordinary ‘human’…”
Ordinary?
He was a beast, ravaging women under the elixir’s burn.
What an intriguing man.
“Haa… I lose. Do as you please…”
“…! Thank you!!”
He bows, smiling.
Truly, a fascinating man.
