How Using My Oppai Skill to Enlarge My Sister’s Breasts Led to Building a Harem - Chapter 35

Chapter 35

<Ai’s Perspective>

“Good day, Ai-san. Studying before class again?”

“Good day, Kanade-san. As an external enrollee, I need to work hard to catch up with everyone.”

This is Shinkou Girls’ Academy, a prestigious school for young ladies nationwide. Now a high schooler, I’ve left home to live in the dorms.

“You’re so refined, Ai-san. Truly admirable.”

“Oh, no… I still have so much to learn from all of you.”

Here, I can’t use the rough language of my old life. “Be a lady”—the school’s first rule.

As a commoner, I had no training in being a refined lady and felt anxious. But thanks to Miyabi-san’s guidance from the Saionji family, I’ve managed to avoid embarrassment.

“You were recommended by the Saionji family, weren’t you?”

“Yes, Ayaka-sama has been very kind to me.”

“I-I see… Well, let’s get along going forward, yes?”

“Of course, Kanade-san.”

Mentioning the Saionji name elicits this reaction every time. Their influence is even greater than I’d heard, surprising me.

(My speech, my appearance—I need to refine them further…)

I’ve grown out my hair and started wearing makeup. My once-tanned skin has regained its fairness through daily care. All this effort is to become a captivating woman—

To be Onii’s—no, Onii-sama’s favorite. To be the one he loves most, I’ll spend three years here honing myself.

Thinking of my beloved brother, I tackle today’s classes with focus.

※

Since becoming a second-year, I’ve doubled down on self-improvement. With my sister Ai starting high school and living in a dorm, there’s less reason to stay home.

So, I’ve been spending every day at the Saionji estate, training under Miyabi-san. But things have changed.

“Nn, juru♡ Jubu… Jurororo♡”

“Ah, Akane-san… That’s a bit intense…”

“No way… Juzozozo♡ Nfu… I have so little time with you, Master… Haamu♡”

“Ku… Aaa!”

“Nfufu♡”

There’s a reason for this—

…

“Akane-san as my personal attendant?”

“Yes, she requested it herself.”

Lately, Akane’s been handling my rides instead of Miyabi-san, who stays close to Ayaka-san due to her pregnancy. I have no complaints.

But it means Miyabi-san, as head maid, is busier. Only she can oversee my studies and training, so delegating other tasks to her maids, like Akane, makes sense.

By the way, I haven’t had sex with Akane-san. It wouldn’t be right to pressure a maid doing her job.

So, I’m grateful she’s willingly giving me a blowjob, surrendering to her passion.

“You need to let it all out to feel refreshed.”

“Yes… Uaa!”

“Nn, juuu♡ Juzo! Jurururu♡”

Akane’s blowjob is fervent, almost zealous, filled with heartfelt dedication.

“Feels so good… Akane-san, kuu…!”

“Master…♡ Haan… Rero♡ Juuuurururu♡”

Her intense suction, her right hand gripping and stroking my shaft, drives me wild.

(She’s so cute… She’s twenty, right? Does she have a boyfriend? No—)

If she had one, she probably wouldn’t be doing this, so she’s likely single.

“Akane-sa… Nn! Uu!!”

“Npu!? Haa… Ngu♡ Nnn♡ Juzozozo…”

She takes my ejaculation, briefly struggling but swallowing without spitting.

“So good…”

“Ngu♡ Ngu♡ — Puha…♡ It was wonderful, Master♪”

Having swallowed every drop, she meticulously licks my cock clean.

(Akane-san’s such a skilled maid…)

“Thank you. I’m thrilled to be serviced by a beauty like you.”

“Hau…♡ Oh, I’m nothing compared to Miyabi-sama…”

My grateful smile makes her blush.

“May I serve you again…?”

“Absolutely, I’d love it every day.”

“…♡ Yes, gladly!”

Thus, I gradually grow closer to the Saionji estate’s maids.

Ping.

(Hm… A message from Nozomi-chan.)

“Thanks to you, Nozomi’s happily attending school today!”

Her smiling photo warms my heart, and I reply.

“Your uniform looks great today, Nozomi-chan. You’re super cute.”

She really is. Now a middle schooler, her uniform makes her look more mature.

“I miss you, Sensei~”

“It has been a while, huh? Wanna meet up and go somewhere fun?”

“Yes! Definitely! I’m so excited for a date with you, Sensei~♪”

Her enthusiasm shines through the text, making me grin. I hadn’t planned a full-on date, but her excitement means I can’t let her down.

“Where should we go…”

Thinking of date ideas to thrill Nozomi-chan, I smile again.

…

“Wow! So many fish~♪”

I chose an aquarium for our date. Why? Nozomi-chan, blind for so long, had never been to one.

“These are tropical fish. Oh, that’s a clownfish.”

“Clownfish…? Wow, so cute~♡”

Clownfish, famous from a certain animated movie, are orange-and-white striped.

“That one’s blue! So pretty…♡”

“True, but those big eyes make it kinda funny, don’t they?”

“Hm…? Ugh, now it looks silly because you said that, Sensei…”

“Haha, sorry, sorry.”

For Nozomi-chan, most fish are brand-new. She eagerly explores each tank, beaming with joy.

(Seeing her this happy makes it worth bringing her here.)

Most girls wouldn’t get this excited at a standard aquarium, but her past blindness makes even ordinary sights extraordinary.

(Life’s fascinating. The longer you endure hardship, the more joy you feel when freed from it…)

Watching her delight, I muse on this.

“Hey, Sensei, look at this!”

“Hm? Let’s see—”

Her radiant smile erases the trouble her healing caused me.

(I wasn’t wrong. I want to keep making people happy…)

Not just with my hands’ power, but through my actions.

My ability heals bodies, but without knowledge, it’s limited. I need to study, think, and gain experience across many fields.

“Sensei, I wanna see the dolphins~”

“Haha, sure. The dolphin show’s starting soon—wanna go?”

“Yay~♪”

She’s still so childlike. Hoping she holds onto that innocence, I let her cling to my arm as we head to the show.

…

The date ends. Though she’s a middle schooler, I shouldn’t keep her out too late, so after a 3 p.m. tea break, I decide to take her home.

“I wanna stay with you longer, Sensei…”

“Your parents will worry if it gets too late, right?”

“Hm… But they said they’d be home late today.”

Her dad’s a salaryman, and her mom’s a nurse, right? Even more reason to get her home before dark. A cute girl shouldn’t be out at night.

Convincing her, I held her hand and walked to her house.

…

We arrived at a stylish home with “Yuki” on the nameplate.

“So this is your place, Nozomi-chan.”

“Yup… Sensei, can you come in for a bit?”

“I don’t mind, but is that okay…?”

I worried her parents might disapprove of a stranger in their home.

“It’s fine! Mom and Dad know you’re the one who healed my eyes.”

“Oh, right. Then I’ll pop in for a bit.”

“Yay! This way!”

Following her lead, I entered the house.

(No steps at the entrance… The whole place is barrier-free.)

“I’ll make tea. Sit on the sofa, Sensei.”

“Sure.”

I wasn’t worried—she’s smart and capable.

“Hm, a fashion magazine… This is…”

On the living room table was a popular teen magazine.

(Satsuki-chan’s in this…)

She’s featured, but I’ve never bought these. The real Satsuki-chan’s way cuter, so while I’m curious, it’s not worth purchasing. By the way, Satsuki-chan skipped high school to focus on modeling.

“You read these, Sensei?”

“Not really. Is this yours, Nozomi-chan?”

“Yup. I can’t read much yet, so…”

She set a cup of tea before me.

“Right, you’re still learning to read.”

“Magazines like this are fun even if I can’t read hard words.”

Makes sense. At her age, she’s into cute clothes.

“Your outfit today’s super stylish and cute.”

“Ehehe, Mom and Dad said I could buy what I like.”

“Haha, you’re so loved, Nozomi-chan.”

“Yup, I love them too~”

Her innocent smile warmed my heart, making me adore her even more.

“Oh, I’ll show you my room, Sensei!”

“Your room?”

“Yup! When I could see, I got a room upstairs.”

(Right, upstairs was dangerous when she was blind, and she needed help…)

She must be proud of her new space.

“Cool, can I see it?”

Curious, I asked, and her face lit up as she grabbed my hand to lead me.

“This way~♪”

Up the stairs, I saw a door with a “Nozomi’s Room” plate.

“Here you go, Sensei!”

“Wow! What a cute room!”

Her room was like a picture book—pale pink walls, adorned with dolls and stuffed animals.

“Ehehe~ I got lots of plushies♪”

She hugged a big bear.

(So cute…)

Even as a middle schooler, playing with plushies is new for her. Her pure expression warmed my heart.

“Hey, let’s play, Sensei!”

“Sure.”

(Like having a new little sister.)

I joined her on the bed for doll play, moving their limbs like they were talking, just like with Ai as a kid. Nozomi-chan squealed with delight.

“More, Sensei!”

We played for a while until she suddenly stared at me.

“Sensei, do you like me?”

“Of course, I love you.”

“Really? Really, really?”

“Yup.”

She leaned closer, asking repeatedly.

“I love you the most in the world, Sensei!”

“Haha, thanks.”

Her cuteness made me pat her head.

“I’m serious, Sensei.”

“Uh, yeah.”

She’s adorable and will be a stunning beauty someday. But I still saw her as a younger girl.

“You gave me so much happiness…”

“Yeah.”

“So—”

She reached for her clothes and stripped.

“—I want to give you everything, Sensei.”

Smiling, Nozomi-chan wore a seductive, womanly expression.
