How Using My Oppai Skill to Enlarge My Sister’s Breasts Led to Building a Harem - Chapter 25
Chapter 25
Even after curing Nozomi-chan’s blindness, I continued my usual routine.
But that peaceful life didn’t last long…
Heading to the clinic as usual, I noticed a message on my phone just before turning the corner to the building.
“My apologies, master. Please do not go to the clinic today.”
“What’s this… From Miyabi-san?”
It seems I’m not supposed to go to the clinic. Puzzled, I start typing a reply when I notice a commotion around the corner.
(Multiple people with cameras… What’s with them? No way…)
Media types are arguing with the bar owner on the building’s first floor. Sensing danger, I pretend to be an ordinary student and distance myself from the scene.
…
Once at a safe distance, wondering what to do, my phone rings—it’s Miyabi-san.
“Are you safe, master? The situation is—”
She explains: as feared, my mysterious power has leaked to the media.
“We controlled information as best we could, but the fact that her eyes were healed couldn’t be hidden.”
True. Nozomi-chan’s been attending school normally since her recovery. People must’ve been shocked, naturally leading to questions about how and where she was treated.
“What’ll happen to me?”
“Your personal information is untraceable, so please don’t worry. I’ll pick you up by car, and we’ll discuss our next steps.”
“Got it.”
I wait as instructed, then head to the Saionji estate.
“Sensei! You’re safe…”
Ayaka-san greets me at the Saionji mansion, visibly relieved.
“My apologies for the trouble, master.”
“No, it’s fine. This is partly my fault.”
It’s obvious when you think about it. An incurable condition healed—especially vision, a noticeable change.
“But I don’t regret treating Nozomi-chan, and no one’s to blame.”
“You’re right, sensei. If anyone’s at fault, it’s those trying to profit off your power.”
Ayaka-san agrees.
“So, Miyabi-san, what’s the plan?”
“Well…”
I’d prefer to relocate the clinic and continue, but—
“It’s best you lay low for a while.”
“Huh?”
“What do you mean, Miyabi?”
“Once information leaks, it’s hard to erase.”
That makes sense. In today’s information age, burning paper records like in old movies is pointless.
“Just hide until things cool down?”
“Yes, but idling would waste time. So—”
Miyabi-san clears her throat and faces me.
“You’ll go on a short-term study abroad to a southern island.”
Thus, to escape the media frenzy, I’m sent overseas.
※
“How did it come to this…”
I’m on a private jet arranged by the Saionji family, heading to the Waheide Islands, south of Japan.
The Waheide Islands, a cluster of hundreds, are a hidden gem unknown to most. They’re a haven for the global elite, with vacation homes, low taxes, and status as a tax haven.
“I barely speak any foreign languages.”
“Fufu, you’ve studied English with Miyabi-sama, haven’t you?” says Akane-san, Miyabi’s subordinate maid, listening to my complaints.
“Yeah, I can manage basic conversation, but…”
“If Miyabi-sama deemed it fine, there’s no issue. Plus, our local contact speaks some Japanese.”
“Really? That’s a relief!”
Honestly, I was terrified my English pronunciation wouldn’t cut it.
“There’s also your phone’s translation function. But…”
“But?”
“I think Miyabi-sama chose this place so you could master English.”
“…”
She’s right. This isn’t just hiding—it’s for my growth. I can almost hear Miyabi-san urging me to become fluent.
“Guess I’ll have to try hard.”
“Yes♪ I’m rooting for you!”
The maid cheers me on.
(I’ll treat it as a short overseas trip while studying English.)
With that mindset, I decide to sleep on the plane until we arrive.
※
“Wow, it’s hot~…”
Japan was mid-winter, but Waheide Island is so warm you can wear short sleeves. The airport reveals vast forests, pristine beaches, and modern buildings—a true resort paradise.
“We’ll continue by car.”
“Okay.”
I hop into the car, which heads toward a local connected to the Saionji family.
(The AC in here is a lifesaver.)
Outside feels like 30°C. Coming from wintery Japan, the temperature swing is jarring. Relaxing in Akane-san’s car, I ponder what to do upon arrival.
(There was a bustling downtown—maybe explore there? Or try some exotic food?)
It’s my first time abroad, so I’m hyped, like a boy exploring an unknown land.
“Wait, is this the right way?”
“Yes, it’s correct.”
She says so, but we’re clearly heading away from the vibrant city with its towering buildings, toward… somewhere else.
(What’s going on?)
I’m puzzled but unfamiliar with the area, so I can’t give directions. I open a guidebook to check.
Waheide’s main island is crescent-shaped, with a beautiful beach in its curve. The north has a modern city, while the rest is forest. We’re heading south—into the woods.
“We’ve arrived.”
“Huh…?”
We’re here already. Stepping out, I see a house that’s unmistakably…
“A log cabin…?”
No, it’s rougher—more like a mountain shack.
“Hey, you got a problem with my house or something?”
A brown-skinned girl, likely a local, snaps at me in fast English, which I barely catch.
“Uh, you are…?”
“That’s my line. You’re Japanese, right?”
“Yeah.”
“Hah! Knew it!”
Her tone feels derogatory, irking me.
“Akane-san, is this the place?”
“Yes, you’ll live here, master.”
A mountain shack… with a prickly girl.
“What’re you whispering about, Jap?”
“Hey.”
I wouldn’t hit a girl, but that crosses a line.
“What’s your deal…?”
“If I did something wrong, I’ll apologize, but that attitude’s uncalled for.”
“…Hmph. Then don’t diss my house.”
“You’re right, that was rude. Sorry.”
I bow sincerely, owning my mistake.
“W-Well… as long as you get it. Come on, I’ll show you around, Japanese guy.”
“Alright.”
“I’ll take my leave. Good luck, master.”
Akane-san drives off.
“Hey, what’re you standing around for? This way!”
“Coming.”
Thus begins my tropical life.
“This is me and my mom’s house. Not big, but it’s enough, right?”
“Yeah.”
It’s truly a wooden house, like another world compared to modern Japan, but that’s probably what foreign places are like.
“I’m Maya. My mom’s Carla.”
They’re a mother-daughter duo. Isn’t it… unsafe, though? When I ask—
“No bad guys come to this island.”
The crime rate is extremely low, as the guidebook noted. Rich in tourism and catering to the wealthy, strict immigration screening keeps criminals out. Despite a small population and GDP, it’s one of the world’s most affluent places.
“How do you make a living here?”
“Work? This.”
“Whoa…!”
Maya tosses me a fruit-like thing—white, elastic, strange.
“Pao fruit. This island’s specialty.”
“Pao fruit…”
It feels oddly familiar, like I’ve heard the name before. Maya says they live off harvesting these.
“Starting tomorrow, you’ll help with the harvest.”
“I’ve never done that.”
“Ugh, city boys…”
“Hey.”
She mocks me again, wounding my pride as a Japanese guy.
“I’ll get good at it fast.”
“Hah, try your best.”
She’s skeptical, but I’m fired up to prove her wrong.
“Also, I’ll show you where to sleep, bathe, and the toilet.”
“Thanks.”
The sleeping area is a simple wooden platform with a mattress—good enough.
“Bathing’s out back.”
I follow her.
“There’s nothing here.”
“There is. The well and this soap.”
It’s completely exposed. Fine for two women, maybe, but…
“People could see you naked.”
“Just don’t peek.”
Fair enough. I nod.
“Here’s the toilet.”
“A pit latrine… First time seeing one.”
No flush toilets in the boonies, I guess.
“Do it in the bushes if you don’t like it.”
“Didn’t say I disliked it.”
It’s way better than the bushes.
That wraps up the house tour. Carla, the mom, will explain more when she returns, so I’m free for now. I unpack near my bed—clothes, toothbrush, phone, charger.
“There’s an outlet… Electricity’s here.”
At least it’s modern in that sense.
“But electricity and no AC…?”
It’s hot—sweat drips just sitting here.
“Guess I’ll bathe…”
Unable to stand it, I grab clothes and head to the backyard.
…
“A hand pump, huh? You work it like this?”
Gripping the metal lever, I pump it, and water flows from the spout.
“Whoa, it actually works… Uses air pressure to draw water, right?”
The principle’s simple, but it’s new to me.
“Hm… Kanji. Made in Japan?”
It’s old but has Japanese markings.
(Not my doing, but kinda proud.)
“Let’s wash up.”
Unable to bear the blazing sun, I strip, stand on the concrete slab, and douse myself with well water.
“Gah, cold!”
Well water, insulated from surface heat, is chilly but refreshing, cleansing my sweaty body.
“Phew. Soap’s next…”
It’s solid soap, not body wash—rare nowadays. I don’t know how to use it.
“Rub it on my body?”
No, better to lather it in my hands. I rub it, creating foam.
“Nice.”
Fully lathered, I set the soap down and scrub. Washing naked in broad daylight in nature feels liberating, fun.
“Haa, awesome.”
I rinse off with more water, feeling refreshed, and reach to dry off—then freeze.
(Forgot a towel…)
I have a small one in my backpack for my face.
“Damn… Wear wet clothes?”
As I ponder—
“Where’s that Japanese guy? Geez!”
A voice from behind.
(That’s…)
“City boys are so useless—huh!?”
“Maya, huh…”
“What’re you…!? Whoa!?”
“It was hot, so I’m bathing.”
She’s shocked, though there’s no point staring at a guy’s body.
“Got something to wipe with? Forgot my towel.”
“W-What…!? Wipe… something to wipe with…? Y-Yeah, of course! Wait here!”
Maya bolts without hearing my reply.
“What’s with her…”
She returns quickly, holding out a cloth without looking at me.
“Thanks.”
“Uh, yeah…”
I dry off and dress, but her response is awkward.
“Didn’t you need help with something?”
“Oh, right. I was gonna have you chop firewood.”
“Got it. Never done it, so show me how.”
“Y-Yeah…”
Following Maya, I learn to chop wood.
“Right foot forward… like this!”
Pakon! The wood splits cleanly. Her practiced movements are efficient.
“Your turn.”
“Alright—Hah!”
Pakon!
It splits. Not bad for my first try.
“Hmph! Not bad… I’ll leave the rest to you.”
“Got it.”
Watching Maya, I noticed her technique resembles martial arts—right foot forward, like swinging a katana, dropping her hips for impact to add body weight.
“Hard wood… Broadleaf?”
Broadleaf trees, common here, are harder than conifers.
“Chopping this much without straining my body…”
Trained in weapon handling, I know heavy weapons like axes are top-heavy. Using their weight beats brute force.
“Use the axe’s weight—like this!”
Pakon!
It splits cleanly with less effort.
Kinetic energy, K=1/2mv², depends on mass and speed. The axe’s speed and weight at impact create the force. Using centrifugal force to accelerate and dropping my hips at the moment of impact—split!
“Feels good. This doubles as training.”
It’s body control practice—converting muscle and weight into energy efficiently, like pro fighters training with wood chopping.
I keep refining my technique, splitting the pile.
…
“Maya, I’m done.”
“What…? Done with all of it?”
“Yup. Finished the whole stack.”
“…Wow.”
It was tough, but I finished before dusk.
“Hmm… Not bad, Ja-pa-nese.”
Maya smiles, not mockingly like before, but genuinely impressed. It feels good.
“Leave heavy work to me.”
I get a bit cocky.
“Heh~ Looking forward to tomorrow, hehe♪”
Her mischievous grin makes me slightly regret my bravado.






































What a cunt, and Miyabi/Akane is a bitch for dumping him here. Although hes a moron for asking NO questions or having any objections to being abandoned in the middle of nowhere.
