How Using My Oppai Skill to Enlarge My Sister’s Breasts Led to Building a Harem - Chapter 46
Chapter 46
Three days had passed since Ayaka-san and I welcomed our child—a healthy boy named Yuichiro.
Why do I sound detached? Because…
“Can’t I go to the hospital yet?”
“No. Saionji and Hojo-in family members are frequently visiting,” Miyabi-san explained.
The Hojo-in are the family of Ayaka-san’s husband. With the heir to both houses born, opportunists are swarming.
“I see…”
I couldn’t brazenly show up, so I was stuck in this restless limbo.
Across from me, nibbling a snack, Maya spoke up.
“Ayaka’s fine, right? No need to worry.”
She was trying to cheer me, the worrywart.
“Yeah… You’re right. Fretting won’t change anything.”
“Yup! I’ll share half my sandwich, so cheer up♪”
She handed me half her maid-made sandwich.
“Thanks, Maya. You’re so kind…”
“Ehehe, here ya go.”
Maya freely shares, even her own things, with me or Carla. Her rule: happiness is for family.
“With a baby coming, gotta eat up.”
“Yup♪ I’ll birth a healthy one~”
“Can’t wait, Maya. I’m so lucky.”
We munched our sandwiches together.
In this happy moment, another issue surfaced.
“Sasahara Satsuki (16) Pregnant, Partner a Commoner Man—”
The tabloid headline blazed on my phone. Satsuki-chan, my girlfriend and model, was top news for her pregnancy.
(She said she’s fine, but…)
Now more popular than idols or actresses, Satsuki-chan’s daily media appearances sparked a firestorm with her comments, trending on SNS:
“Young births have risks, they say… But nobody mentions high-risk older pregnancies.”
“They complain about low birth rates but criticize us for having kids. No wonder numbers drop.”
These quotes enraged some women’s activists, who bombarded her with vitriol. But the tide turned, sparked by her teen fans:
“Just old ladies’ jealousy~”
“Past 30 with no kids? That’s weird.”
“Better to have kids young with a hot guy, right?”
The activists lost it, but the counterattack didn’t stop. General support for Satsuki-chan grew:
“Young births have perks—more energy, support from young parents.”
“If parenting’s tough, the government should help.”
“Better than infertility treatments later…”
“Taxing us for ‘birth rate fixes’ and new agencies, yet record-low births? The system’s broken.”
Pent-up public frustration erupted. Some argued young parents increase abandoned kids, but avoiding that risk led to the current low birth rate. It’s obvious—without some risk, numbers won’t rise. This sentiment spurred young politicians to back Satsuki-chan.
Over days, society seemed to shift toward youth-driven change.
…
“Thanks for the meal.”
“Yummy, right?”
“Yup. So, Nii-cha, let’s have sex♡”
From hunger to lust—classic Maya, true to her desires and Waheide’s candid culture.
“Cool, but is the baby okay?”
Her belly’s growing, so vaginal sex might be tricky.
“Then use my butt.”
“Anal? I’m down.”
“Yay!♪”
Eager to try anal, she clapped joyfully.
“To the bedroom?”
“Yup!”
We headed to sate our desires.

“You’ve got naughty eyes♡”
“Do I?”
Stress from not seeing Ayaka-san and our child had dulled my focus on sex.
“Guys gotta be naughty, you know?”
“Maya…”
I adore this about her. Initially wary, once trust was built, she embraced all of me with deep affection.
“Ehehe, getting bigger, huh?”
She stroked her womb, reporting our baby’s growth.
“Yeah, it’s beautiful, Maya. Our precious child.”
“Ehehe, Nii-cha♡”
“Maya…”
I kissed her lips, love exploding.
“Nn♡ Chu… Haa♡ Nnu♡ Chuu… Chupa♡”
“Maya… Maya…”
Some might call it indecent, with Ayaka-san’s child just born. But the girl before me is carrying my child too, striving to birth it. How could I not feel love?
“I love you, Maya.”
“I love you too, Nii-cha…”
Sucking each other’s lips, we gazed. Her healthy tanned skin, golden hair, and usually childlike face now held a woman’s allure.
“Hey… Let’s do it quick♡”
Gulp…
Turning, she spread her cute butt muni♡.
My core throbbed, desire igniting like a flame after days of restraint.
“Maya! Jyu… Jyuu…!!”
“Aa…♡ Nii-cha… Don’t lick my pussy…♡ Nnu~~~♡”
“Haa… Haa… Maya! So cute…!”
The naughty taste of a girl, after so long, was divine to my aroused body.
(Maya’s smooth butt… And…)
“Yaan♡ That’s… my butt hole…♡”
“Jyu…! Rerorero… Jyuzuzu!!”
I tongued her pink anus, licking and sucking.
“That’s not for licking, Nii-cha…!”
“Jyururu…! Gotta loosen it for entry…”
We’ve had frequent sex, but her anus is new. I needed to massage it to avoid pain.
“Not gross?”
“Jyuzu… No part of my beloved’s body is gross…?”
Momi♡ Munyuu♡ — Jyu♡ Nyuru♡ Guriguri♡
Kneading her butt, I probed her anus with my tongue. Her voice sweetened, body relaxing.
“An♡ That… Hyaa♡”
“See, my tongue’s in already…”
“Slippery… Feels good…♡”
She squirmed eagerly. Judging it ready, I withdrew my tongue.
“Nau! You’re not getting away, Nii-cha…!”
“Whoa, Maya!?”
Retaliating for the teasing, she pounced, gripping my rock-hard cock.
“Uaa… Maya…”
“So hard… Such a perv♡”
Her desire-filled eyes locked on me.
“My butt’s itching, I can’t wait! Nfu♡”
“Ugh…! Going inside Maya…!”
Straddling me, she aimed my cock at her anus and lowered herself.
Zu♡ Nyuuuu~~~♡
“Nn~~~♡ Big cock… Going in… Aaa~~~♡”
“Maya… Kuu, so tight…”
Despite being her first anal, her butt swallowed my cock willingly.
(Maya… Too cute… I can’t hold back.)
Gugugu…!
Aroused by our love, my cock thickened, stretching her anus tight.
“Au!? Nii-cha… It got bigger…”
My excitement was hurting her.
“I’ll rub your oppai, Maya.”
To ease her, I used my hand’s ability.
Munyu♡ Momi♡ Momi♡ Gunyun♡
“Aa♡ Aa♡ Feels good♡ My oppai are tingling…♡”
“Relax more… Good, Maya… Your butt’s opening…”
“Amazing… Nii-cha♡ My oppai are buzzing~~~♡”
My palms seemed made to pleasure girls, instinctively finding meridians to maximize sensation. Then I noticed something.
(Deep in her oppai… This is…)
Sensing a change, I kneaded her breast core firmly.
“Auu♡ N-No! Something’s coming! Auuu~~~♡♡♡”
Pyu, pyuu~~~♡
“W-What’s this!? From my oppai…♡ Aa~~~♡”
At 13, Maya’s breasts spurted milk. Was it from my daily massages? Undeniably, her young chest sprayed arcs of baby milk.
“Your oppai are making milk, Maya.”
“Milk…♡ For our baby…♡”
“Exactly… You’re too cute, Maya.”
I couldn’t resist. Pride and conquest surged as I’d altered her body.
Dochu♡ — Dochu♡ Dochu♡ Dochu♡ Dochu♡
“Haa♡ My butt…♡ Getting pounded~~~♡”
“Maya! Aa! Perfect!!”
(This girl… She’s my woman!!)
Dochu♡ Dochu♡ Dochu♡
“So good♡ Your cock…♡ I love it~~~♡”
“Me too, Maya’s butt hole! Love it!!”
Zuko♡ Zuko♡, my veiny shaft pistoned her tight anus, a natural onahole unlike her pussy.
“Aa…! Cumming! First shot!!”
“Aa♡ Hot~~~♡ Nhaa~~~♡”
Unleashing a flood of semen, I painted her intestines white with ferocious force.
Dobyu~~~♡… Byuku♡ Byuku♡ Byuku♡
“Nii-cha♡ Feels good…♡ My head’s flying~~~♡”
“Aa! Won’t stop… I’ll make you feel even better…”
Dochun♡ Dochun♡ Dochun♡
To conquer her anus, I activated my ability, pummeling her with my spurting cock.
“Ngu♡ No, no… No~~~♡♡♡”
Maya convulsed, screaming her loudest today.
Dochun♡ Dochun♡ Dochun♡
Ignoring it, I lifted her legs, driving my rod deeper.
Dochun♡ Dochun♡ Dochun♡
“Aga♡ Hii♡ Hii♡ My butt’s breaking~~~♡”
“It’s okay!! Trust me, Maya!!”
“Auu! Cumming, cumming… Aaaa~~~♡♡♡”
She climaxed again, her anus milking my cock.
“Maya! Second shot! More to come!!”
“Oh♡ Ooo~~~♡ My butt pussy’s going dumb~~~♡”
“Even if it does, I’ll love you forever, Maya!”
“Nii-cha~~~♡ Aa, cumming again~~~♡”
Her anus hooked, she came repeatedly, driven wild by my cock.
…
“Do it every day, Nii-cha♡”
“Daily might ruin your butt.”
“You’ll love me anyway, right?”
“Yup, I love you, Maya… But not daily.”
“Muu~”
Pouting cutely, she melted when I petted her, clinging to me. As we flirted—
“Master, Lady True Maya—dinner’s ready.”
“Oh…”
It was well past dinnertime, Akane-san calling from beyond the door.
(Was she listening…?)
Embarrassed, I realized our intense sex sounds were overheard.

<Saionji Main House>
“Been a while, Father.”
“What, Kazuma? How many years since you showed your face?”
A man in his late 40s bowed courteously, answered by a chilling voice from a man past 70. Frail with age, the elder’s white beard, Nishijin kimono, and piercing gaze exuded timeless authority.
“…”
“What’s a failure like you doing here?”
“Father…”
Their long-awaited reunion held no joy, only distance.
“Don’t tell me you’re meddling in the succession.”
“I’ve come to request regarding that.”
“You fool!!”
The heavy dark brown desk thudded loudly. Yet Kazuma, who’d sparked his father’s wrath, didn’t flinch.
“I know it’s shameless, but please…”
“…”
Kazuma bowed deeply, waiting for his father’s breathing to steady. After a pause, the elder spoke calmly.
“You changed after that accident.”
“…”
“Since then, you’ve been a shell. Why go this far now?”
“Because—”
Kazuma closed his eyes, recalling the past, then answered firmly.
“I found a man worthy of my daughter.”
“Hm.”
The elder leaned back, the leather chair creaking, pondering as the clock ticked a full cycle.
“My eyes aren’t blind. You think I don’t know?”
“Of course not, Father.”
“He’s ordinary. Compared to Hojo-in’s third son, he’s nothing. Unfit to lead Saionji.”
“You’re right.”
Ayaka’s beloved is hardworking but a commoner with average talent. He couldn’t command elite circles, far inferior to the Hojo-in scion.
They agreed on this.
“But—”
“Oh?”
“As a person, he’s exceptional.”
“Haha! What nonsense…”
Leading doesn’t always need ability, but people won’t follow the inept—a hard truth.
“Saionji is a titan. No ordinary man can helm it. You, of all people, should know.”
“Yes—but he could surpass me, become extraordinary.”
“Really…?”
Baseless speculation. With the future uncertain, choosing the best now is logical.
“Pointless. A waste of time.”
“Father…”
“Leave. I’ve no time for your drivel.”
The elder’s resolute tone silenced Kazuma.
“Sorry for taking your time. Excuse me.”
“…”
The air grew heavy, and Kazuma left.
Alone, the elder’s sharp gaze lingered on the door.
“That man…”
Muttering to the void, he continued.
“That accident six years ago was unavoidable.”
A truck ran a signal, hitting a crosswalk. A young child couldn’t dodge. Kazuma blamed himself ever since.
“Acknowledge her? Impossible.”
A child with a foreign maid, not even a concubine… Raised as a commoner. If recognized as Saionji, she’d have had protection, a regret Kazuma still held.
“What a fool—”
Seeing him, less hollow than before, was something.
“Granddaughter’s beloved, huh… My stance won’t change.”
Saionji’s turmoil would cripple the economy. That couldn’t happen.
“But I’ll keep him in mind.”
The elder’s lips curved slightly upward.
