How Using My Oppai Skill to Enlarge My Sister’s Breasts Led to Building a Harem - Chapter 18

Chapter 18

Miyabi, unsatisfied by a single blowjob, spread her legs, offering her hole for my use.

“Is my body not enough?”

“Miyabi-san… I love you…!”

“No, master, you’re Lady Ayaka’s… Nnu♡”

I didn’t want to hear more, so I silenced her with a kiss.

“Hann♡… Chu♡ Kissing is for your wife… Juu♡ Jururu, Chuzu♡”

Sex for relief is fine, but kissing isn’t? Does she only see me as Ayaka’s partner? The thought stings my chest.

“Is kissing me unpleasant?”

“N-No, it’s not… But, nju♡ Haa… Chururu♡”

I won’t let her finish. I want her to see me as just a man. If it’s not unpleasant, there’s a chance.

“I’m going in, Miyabi-san!”

“Aa! Nn♡”

Her pussy, dripping with slick juices, takes my cock smoothly.

“Your pussy’s so hot…”

“Ku, uu…”

“You’re cute, Miyabi-san.”

“U, uu…!”

Her pussy tightens, kyuun♡. Unlike our last sex, where I couldn’t see her face, now I can see her clearly.

“D-Don’t look…”

“You’re feeling it, right?”

“N-No… I’m not…!”

“Then I’ll make you feel it!”

Nuchu♡ Nuchu♡ Nuchu♡

“Ku, fuu…♡”

“Nhaa… It’s sucking me in…”

Her already tight pussy, now aroused from the blowjob, clings stickily.

“Don’t… look…”

She turns her red face away. I crave to see her cute expression more.

Pan! Paan♡ Paan♡ Paan♡

“Aa! No…♡”

“Show me your face, Miyabi-san!”

I thrust, leaning over her, whispering in her ear.

“I’m so happy to have sex with someone as amazing as you!”

“S-Such… I’m not Ay— Nn♡ Chu♡ Jururu, Juzozozo♡”

I kiss her before she says Ayaka’s name, grabbing and kneading her breasts.

Gunyuu♡ Muniu♡ Guniii♡ — Pan! Pan♡ Pan♡ Pan♡

“Hau♡ S-So rough… Ah♡ Ah♡ Ah♡”

“Feels good, right, Miyabi-san?”

“Ann♡ Nn♡ Nn♡ Nn♡ I’m not… feeling good…♡ Nnn!”

Incredible. My hands sense her body melting with pleasure, yet she endures.

“Suuu… Your body smells amazing…”

“N-No, don’t smell my armpits…”

“I love your scent, Miyabi-san.”

Her aroused body sweats profusely, her armpits exuding thick pheromones.

“Your penis… it’s throbbing inside…”

“Because I love you! Haa, haa, haa!!”

“Hii♡ It’s getting bigger♡”

Zuchuu♡ Zuchuu♡ Zuchuu♡ Zuchuun♡♡

“Hii♡ Ah♡ Ah♡ Aa♡”

“Are you close…?”

“Nn♡ I’m not… I’m not feeling…”

Dochu♡ Dochu♡ Dochu♡ — Dochun!!

(No… Her pussy’s so tight, I’m at my limit…)

“I’m cumming! Uh…”

“Nguu♡ —…~~~~♡♡♡”

Defeated by her gripping vaginal walls, I release, dobyu♡, deep inside. Her walls, molded to my cock, writhe, milking my semen.

Byuku♡ Byuku♡

“Ugh… It’s squeezing me…”

“Kahaa♡ Ha♡ Ha♡ Ha♡”

I’m not the only one who came. Miyabi trembles rhythmically, accepting my load.

“You came too, right, Miyabi-san…?”

“Fuu… You’re imagining it.”

Again. If she won’t admit it, I haven’t satisfied her.

“Then I’ll keep going, harder.”

“…! Do as you please.”

My head burns. I just want to love her, but something keeps blocking us.

“Hn! Hn! Hn! Hn!”

Zudon♡ Dochu♡ Dochu♡ Dochu♡ Dochun♡

“Ugu♡ U♡ Ah♡ Ah♡ Ah♡”

I thrust relentlessly, determined to win her, becoming a beast to claim Amakawa Miyabi.

…

“Ah…♡ A… U…”

“How was it, Miyabi-san? You felt it, right?”

“…No… I didn’t… feel…”

I pushed her to the edge, but her answer stays the same. Despite her dazed state, her incredible willpower rejects my confession.

“I see… But I won’t give up. I’ll make you mine…”

“That… depends on you…”

With those words, she passes out, her final expression oddly smiling.

Another maid arrives, tending to her.

“Sorry for going too far… Let me help clean.”

“No, relieving the master’s pent-up desire is a maid’s duty.”

I’m refused. Unable to win her love or even help clean, I’m filled with defeat.

What baffles me is not just her rejecting my confession but denying her pleasure. Her body was clearly in ecstasy—how can she say she felt nothing? I can’t understand.

But I can’t forget her. I’m driven to make her admit she feels it and loves me.

“I’ve gotta try harder… Alright!”

I stand, fired up. A new goal forms: make Amakawa Miyabi fall for me and share the ultimate sex, body and soul connected. With this ambition burning, I vow to keep improving.

※

The Saionji estate, vast and managed by just ten maids, would typically be understaffed. But with an exceptional head maid and her trained team, it thrives.

At dawn, when the household sleeps, what does this head maid do?

“Nn! Haaa♡ Harder, harder♡”

On the bed her master used, she indulges in masturbation.

Kuchu♡ Kuchu♡ Kuchu♡ Toro… Torotoro♡

“Aa! So good… Master… It feels so good♡♡♡”

Amakawa Miyabi, imagining her master, frantically pleasures herself.

Kuchukuchu♡ Nuchu♡ Zububu…♡

“Aoo♡ Fingers aren’t enough… Something thicker, ruin me♡”

Like her body’s on fire, she moves her fingers fiercely.

“Love you! Love…♡ I… love you, master…♡ U~~~aa♡♡♡”

Feverishly, she confesses to the void, her passionate desire for her beloved man burning.

“Haa…♡ Haa…♡ Haa… Fuu…”

Reaching climax, her body cools. She quickly tidies herself and changes the sheets.

“…Wasted five minutes. I must make up the time.”

Muttering, she adjusts her minute-by-minute schedule. But another thought lingers.

(You can’t be satisfied with someone like me yet.)

“Until master becomes a true man… I’ll endure…”

With that resolve, Miyabi returns to her dignified role as head maid.
