How Using My Oppai Skill to Enlarge My Sister’s Breasts Led to Building a Harem - Chapter 27
Chapter 27
After playing at the beach, we returned home before noon, eating the meal Carla prepared.
“Mmm… Delicious. Japanese-style seasoning again?”
“Yes, Maya always asks for it,” Carla says.
“C-Cuz it’s not tasty without soy sauce…” Maya mumbles.
Right, Maya grew up in Japan. With the island’s abundant seafood and soy sauce, the food satisfies even my Japanese palate.
“I love this flavor too.”
“H-Hmph… Good to know,” Maya says.
“Hehe♪” Carla chuckles.
The three of us enjoy Carla’s cooking over casual chatter.
…
After lunch, while Carla does laundry, I hang out in Maya’s room.
“By the way, why’d you come here?” Maya asks.
Three days in, it’s a bit late to ask, but it shows we’re warming up. I briefly explain the situation.
“So, you healed that girl’s eyes, and got kicked out of your country?”
“Kicked out’s a bit strong…”
“Ugh, typical Japanese…”
Before her opinion of Japanese people sours further, I shift to an earlier topic.
“Are you worried about your nipple color?”
“W-W-What’re you saying!?” Maya stammers.
“Lots of women worry about it. I’ve handled cosmetic treatments too.”
I explain melanin pigmentation and offer to lighten it.
“R-Really? It’ll get prettier?”
“Yup.”
It’s the power that got me exiled, after all.
“You’re not just trying to do something pervy, right…?”
“Nope.”
“Fine, I’ll trust you… a little.”
“Cool, let’s get started.”
To address Maya’s insecurity, I begin massaging her, even here.
…
Maya lies on her bed before me.
“Take off your top.”
“Ugh… Fine…”
Reluctantly, she removes her shirt, covering her chest.
“I don’t have my usual massage oil, so I’ll use this.”
Without my oils from Japan, I borrow edible pao fruit oil from the kitchen. It’s viscous but harmless.
“Nn… It’s kinda sticky…”
“Don’t get it on your hands.”
“Got it… Like this, right?”
Maya, still shy, moves her hands aside, revealing her cute nipples.
“Yup, I’ll rub in the oil.”
I spread pao fruit oil over her breasts.
“Nn… Haa… Uun♡”
I’m practiced at this, quickly finding her sensitive spots and stimulating them with my fingers.
“W-Why… does it feel… like this… auu♡”
While kneading her soft breasts, I read her body’s signals.
(No health issues. Her chest is still growing but nearing its peak.)
She’s an early bloomer, her body nearly mature at twelve.
Munyu♡ Mugyu♡ Gyu gyu♡
“Haanu…♡ Aa… kuu♡”
Maya tries to stifle her voice, but sweet moans escape.
“The oil’s set. Now for the massage.”
“Wha!? T-That wasn’t… Nnhiii♡♡♡”
Using the oil, I knead her breasts upward, milking them.
Gu… nyururu♡ Nyuruuu♡
“Hau♡ W-Wait, that’s… too much…♡”
My hands mold her soft flesh gunyun gunyun♡, drawing sweet melodies from her.
“This activates the nerves.”
“Ii, hiii…! My oppai… they’ll break…♡”
They won’t. I’ve only seen people delighted by prettier breasts.
I continue massaging, pushing her body to its limit.
“Haa♡ Haa♡ Haa♡ No more…♡”
Her body’s fully relaxed, in peak condition.
“Now I’ll work on the pigmentation.”
“Haa? W-What… are you…♡”
Juuuuppa♡ Juu♡ Juu♡ Jururu♡
“Nnhiuu♡ Why… are you sucking… my oppai…♡”
“Nju! Like this… I suck out… the melanin, zudzu!”
I latch onto her nipple, sucking loudly.
(She’s so sensitive, still young.)
“Hiuuu… Aa, uu♡”
“You’ve never played with your oppai?”
“N-No… Never…”
(Living alone with her mom in the mountains…)
Her sex education is likely limited.
“I’ll go gentler.”
I stop sucking hard, licking her areola in circles, massaging softly.
“Nn♡ That… tickles…♡”
“Rero… Better than before, right?”
I coat her nipple with saliva, rolling it with my tongue.
“Yeah, but… the tip… feels tingly♡”
“N… rero. That means it’s working—rerorero, chuu…”
“Aan♡ You’re sucking again…♡”
I need to suck after loosening with my tongue.
“It’s getting prettier bit by bit.”
“Nn♡ Really…?”
Determined to help her, I lick and suck her nipples for about thirty minutes.
“It’s lightening a bit.”
“Really!?”
The effect’s starting to show.
(Her stamina’s about done…)
“Let’s stop here for today.”
“Eh? O-Okay…”
“You did great, Maya.”
I gently pat her panting head.
“Again tomorrow?”
“Yup. Keep this up, and they’ll be pretty pink.”
“R-Really…?”
“So, tomorrow?”
“Yeah!”
Thus, I promise to suck Maya’s breasts daily.
…
“Phew… That’s enough wood chopping.”
After massaging Maya, with time to spare, I chop firewood.
(Damn… My pants are tight.)
Despite treating Maya like a kid, not having sex for three days makes her cute moans replay in my head, heating my groin.
(Maybe tonight, alone…)
Rarely masturbating lately, I decide to hold off for now.
But that plan becomes unnecessary.
※
I devour Carla’s delicious dinner, going for seconds.
“I’m so happy you eat so much♪”
With a beauty like Carla cooking masterfully, I could eat endlessly. Worried about overeating before my protein shake, my growing body digests quickly.
“Ugh… The protein’s making me hornier…”
Unable to hold back, I stand to find a private spot to relieve myself.
(Outside’s better…?)
“Hey… Something wrong?” Carla calls as I head out, groin bulging.
“Uh, just…”
“Fufu, I get it. You’re young♪”
She smiles at my bulge, not teasingly.
“Come here.”
Carla gently takes my hand, leading me to the back of the kitchen.
“A young guy can’t hold back in a place like this, right?”
“Haha… Sorry.”
“It’s fine. Now…”
Her sweet feminine pheromones fill my nose.
“Let’s feel good together?”
Carla strips, revealing her glistening pussy.
…
Zuchu♡ Zuchu♡ Zuchu♡ Zuchu♡
“Nn… So big♡”
“Ugh… Carla-san…”
I thrust my fully charged cock into her raised hips.
“Feels… good… aa…”
“I’ve wanted to have sex with you… an♡”
“Haa… haa… haa! Haa! Kuaaa…”
Carla’s pussy feels unreal. Whether it’s her or my three-day abstinence, my cock’s hypersensitive, feeling every fold of her vaginal walls.
Zuju♡ — Paan♡ Paan♡ Paan♡ Paan♡
“Nhaan♡ So good… Hard and thick♡ A first for me♡”
“Carla-san… Carla-san!”
My primal instincts urge me to release my pent-up semen.
“Carla-san! Excuse me!”
“An♪”
I lift her hips, setting her on the dining table. Dishes clatter as her perfect, beautiful body lies before me. Like a starving beast, I devour the pleasure.
Paan♡ Paan♡ Paan♡
“Kuuu… Irresistible. It’s clinging to me…”
“Nn♡ Nn♡ Nn♡ So good♡ Thrust harder…”
Her sweet moans spur me to speed up my hips.
Pampampan♡ The sound of flesh slapping echoes through the house.
Lost in my first sex in days, I quickly reach my limit.
“Can’t… All this buildup’s coming out!!”
“Aa♡ Aa♡ Shoot it! Give me your thickest load♡”
“Gu… Uu!”
With a dobyu♡, my long-stored semen erupts, filling her vagina and spilling out.
“An♡ So vigorous♡ Fufu… But you can keep going, right?”
“Khaa… Of course!”
Even mid-ejaculation, I feel the next load ready. Three days without sex—I’m nowhere near done.
Zu… jun! Dochuu♡ Dochuu♡ Dochuu♡ Dochuu♡
“Haa…♡ Nn… So good♡ More, more♡”
Scattering semen, I indulge in sex purely to sate my lust.
“You haven’t had sex in days, but…”
Carla gazes at me seductively.
“It’s been five years for me♪”
Her sultry smile says it all.
She was more pent-up than me, and our midnight tryst didn’t end until she drained every drop of my semen.
※
The next day.
“Uuu… Idiot, idiot… Stupid Japanese guy…”
“???”
At breakfast, Maya’s red-faced and fidgety.
