How Using My Oppai Skill to Enlarge My Sister’s Breasts Led to Building a Harem - Chapter 50.1: Nozomi and Maya

Chapter 50.1: Nozomi and Maya

I finally settled the turmoil over the Saionji family headship, officially becoming engaged to Ayaka-san. There was a bit of a tussle with Miyabi-san—Miyabi-neesan, I should say—but that’s water under the bridge. For now, I’ve reclaimed a peaceful routine, savoring my second-year high school summer break to the fullest.

Still, there’s something I can’t ignore.

The girls I’ve gotten pregnant.

Until recently, I was shackled by “social responsibility,” but embracing my desires has set me free.

(I love girls… So I’ll love the ones I fall for, all the way to the end.)

Money, future responsibilities—none of that’s a problem anymore, not for someone set to be the Saionji proxy head. If a girl wants to bear my child, I’ll joyfully share my love with her.

“But to do that, I’ve gotta polish myself even more…” I muse.

Building deep bonds with so many girls means I need to be solid—someone who can hold their hearts. So, I’ve been using the summer to dive into intense training and hardcore studying. Today, though, I’ve got a rare visitor.

That person is—

“Hey, Sensei♪” she chirps.

“Hey there. It’s been a while since we’ve met like this, hasn’t it, Nozomi-chan?” I reply.

“Sensei’s super busy… Can’t be helped,” she says with a smile.

It’s Nozomi-chan, the formerly blind girl whose eyes I treated. She couldn’t see until six months ago, so even during summer break, she’s been studying at school. We’ve been chatting daily on a messaging app, and when I heard about her grind, I invited her to hang out for a break.

“Your house is amazing…” Nozomi-chan marvels.

“Haha, my house… Well, I guess it is,” I chuckle.

This is the Saionji annex where Ayaka-san lives. As her husband-to-be, calling it my home isn’t wrong.

“Anyway, come on in, no need to be shy,” I urge.

“Okay, thanks for having me♪” she beams.

Her radiant smile warms me as I gently place a hand on her shoulder, guiding her into the mansion.

I lead Nozomi-chan to a serene, white-toned Western-style room. Settling onto a plush sofa, we start chatting.

“So, when I was in a pinch, that kid totally saved me!” she says, eyes sparkling.

“Hehe, that’s awesome. Sounds like a great friend,” I reply.

Nozomi-chan eagerly shares her school stories. She attended a school for the blind before transferring to a regular one, where reading’s been tough. But her hard work and quick learning have helped her blend into her class fast.

“You’re incredible, Nozomi-chan. Really putting in the effort,” I praise.

“Y-You think so? I mean… Before Sensei fixed my eyes, I couldn’t see anything, so now everything I see is just so fun!” she says.

“Got it. If you’re happy, that makes me happy too,” I tell her.

I pat her head gently.

(Has she grown a bit taller?) I wonder.

It’s been just over six months since we met, and Nozomi-chan’s now a proper middle schooler. Since our first time together, she’s only grown more charming as a girl.

“Sensei…” she starts, her voice soft as I stroke her hair. “Nozomi wants… more—”

Her eyes glisten, torn between longing and hesitation, gazing at me intently.

Then, an unexpected intruder bursts in.

“Nii-cha! Let’s play!” a voice calls.

“Maya,” I say.

It’s Maya, my lover who lives in this Saionji annex. Rubbing her noticeably pregnant belly, she strides in with a boundless grin.

“Hm? A guest… Who’s she?” Maya asks.

“Hey, Maya,” I chide.

“Uh… I’m Yuuki Nozomi…” Nozomi-chan introduces, shyly.

Maya means no harm, but she’s not big on formalities.

“Hmm, I’m Maya. Nii-cha’s lover,” she declares proudly.

“Fweh?” Nozomi-chan blinks, flustered.

Maya’s blunt confidence throws her off. To smooth things over, I start explaining how I met Maya and what’s happened since.

“Okay, so—” I begin.

Life abroad, getting “kidnapped” by the queen, Maya following me to Japan because she couldn’t bear to part—and now carrying my child.

“Maya-chan’s… thirteen, right?” Nozomi-chan confirms.

“Yup!” Maya nods.

“…Same age,” Nozomi-chan murmurs.

“Oh? You’re thirteen too, Nozomi?” Maya asks.

“…Yeah,” she replies.

Nozomi-chan stares at Maya’s swollen belly, then glances at her own body, her gaze dropping.

“Hey, Nii-cha’s baby’s moving♪” Maya chirps.

“For real? …Wow, it is. Like it’s eager to come out,” I say, feeling her belly.

“Gonna have a super healthy baby!” Maya beams.

“Can’t wait, Maya…” I smile.

Her bright grin melts me, and I gently hug her precious frame.

“More, hug tighter♪” she giggles.

“You’ll squish the baby… There, there,” I soothe, patting her head instead.

“Ehehe~” she laughs.

(So cute… Gotta make Maya and the baby happy, no matter what) I vow.

Having a girl bear my child feels like the ultimate honor for a man—a crystal of love, life’s most sacred gift.

My love for Maya overflows, and I end up cuddling her despite our guest.

“Staaare…” Nozomi-chan watches.

“Ah! Sorry, Nozomi-chan,” I apologize.

“Hmm? You like Nii-cha too, Nozomi?” Maya says, catching her vibe.

“Y-Yeah… Nozomi really loves Sensei,” she admits.

“Cool. Then we’re the same!” Maya grins.

“Maya-chan…” Nozomi-chan softens.

Something clicks between them, and they clasp hands, laughing. Normally, two girls the same age liking the same guy would clash, but my situation’s a bit… unique.

“Nii-cha’s an amazing guy with tons of lovers, so you gotta step up, Nozomi!” Maya encourages.

“U-Uh?” Nozomi-chan blinks.

“Make lots of babies!” Maya adds.

“Whoa, Maya?!” I interject.

I rush to stop her—saying stuff like that might make Nozomi-chan take it seriously.

“Guys are happiest when girls have their babies,” Maya insists.

“I-I see… I thought so…” Nozomi-chan nods.

The two girls plop onto the floor, diving into their own world. The air feels too delicate for a guy like me to barge in.

“And, like… whisper whisper…” Maya murmurs.

Oblivious to me, Maya leans in, whispering something to Nozomi-chan, both giggling.

“Really…?” Nozomi-chan gasps.

“Yup! So, go for it, Nozomi♪” Maya cheers.

“Thanks, Maya-chan!” Nozomi-chan beams.

Their secret chat wraps up. I stare, clueless, which seems to amuse them, their laughter bubbling like little bells.

“Kusukusu, I’m heading out. Come back anytime, Nozomi!” Maya says.

“Yup, thanks, Maya-chan! See you!” Nozomi-chan waves.

“Have fun~ Nishishi♪” Maya winks, slipping out.

(What was that? Them getting along is great, but…) I puzzle.

As I ponder, the remaining girl turns to me, her expression serious.

“Sensei… What do you think of Nozomi?” she asks.

“I love you,” I answer instantly.

“Thank you. But… But Nozomi hasn’t gotten your baby…” she trails off, her voice small.

“T-That’s…” I falter.

Her age, social norms, her family—too many hurdles stand in the way of a girl as young as Nozomi-chan having a child. I start explaining each one.

“Maya-chan… She’s allowed to have one?” she presses.

“…Maya’s not Japanese,” I say.

“Is that important?” she asks.

“…” I’m stumped.

I know countries are just concepts, arbitrary lines drawn by people.

“Because of the law?” she tries.

“…Maybe,” I mumble.

Laws change yearly. Adulthood, marriageable age—they shift with time. Such flimsy rules can’t satisfy her heart.

“Sensei… Is Nozomi not attractive?” she asks, her voice trembling.

“Huh…? Oh—” I start.

Lost in thought, I hadn’t noticed—Nozomi-chan’s stripped to her underwear.

“Nozomi wants to give everything to Sensei…” she whispers.

“Nozomi-chan…” I breathe.

My eyes lock onto her beautiful, bare skin.

“Please, Sensei… Come to me,” she pleads.

“Okay,” I nod.

Faced with such a lovely girl’s invitation, I let go of all my overthinking.
