How Using My Oppai Skill to Enlarge My Sister’s Breasts Led to Building a Harem - Chapter 29

Chapter 29

Learning about Maya’s past through Carla’s stories was painful, but it fuels my drive to make her happy.

“Maya, you’ve got sauce on your mouth.”

“N? N~~~…”

“No helping it…”

I wipe around Maya’s pouting, playful lips. She’s become inseparable, always by my side, sharing meals and sleep.

“Hey, hey! Let’s play, Nii-cha!”

“Sure. What today?”

Maya prefers running outside over indoor games, so we often play tag.

“Gotcha!”

“Agh! Caught!”

We wake, eat, harvest pao fruit, then spend afternoons on chores, living leisurely. This island life has become a source of joy for me.

Of course, my relationship with Maya continues—

“Aa♡ A~~~♡ I love you, Nii-cha♡”

“There, there, I love you too.”

And with Carla—

“Is it okay… for me to…?”

“Haaan♡ Fufu♪ Women have desires too, you know?”

Juu… rururu♡ Jubu, jubo… jubo♡

“Aa… Your mouth feels so good, Carla-san…”

“And this country isn’t monogamous, you know…?”

Right, Waheide Island has no restrictions on love or marriage. It allows polyamory, with no limits on age or gender—lovers can freely form families. I’m not a citizen, so it doesn’t fully apply, but…

“Not just Maya… Look at me too…”

“Y-Yes!”

In a country like this, I don’t need to choose.

“Let’s feel really good!”

“An♡”

Paan♡ Paan♡ Paan♡ Paan♡ Paan♡

I have sex with Carla nearly every night to ease her loneliness.

※

“Hup! …That’s the tenth tree.”

“Let’s take a break?” Maya suggests.

I descend from a harvested pao tree and catch my breath. She used to race me up trees, but now that we respect each other, we work at a relaxed pace.

While sipping water during the break…

(Hm? Where’s Maya going?)

I spot her heading off alone.

(Going deep into the forest alone? That’s dangerous.)

Since realizing I love her, I’ve grown overprotective. She’s so precious, so adorable.

“Might as well follow.”

If she’s in danger, I’d regret it forever. Deciding to check, I follow her path.

…

“Nn… Haaaa♪”

I faintly hear Maya’s voice.

(This way?)

Hearing trickling water, I think she’s there and move forward—then stumble upon an unexpected scene.

There’s a girl with her pants down, golden liquid arcing from her tight slit—Maya, the one I was looking for.

“N-Nii-cha!?”

“Sorry, Maya!”

I didn’t mean to peek, but I’ve seen her peeing.

Jorororo…♡ Jororo…♡

“A, auuu…! It won’t stop…!”

Shocked at seeing a girl’s urination for the first time since my sister as a kid, I’m flustered.

(That much comes out… Gulp…)

The beautiful liquid from my beloved’s body.

Joro♡ Jobobobo…♡

The sound of it hitting the ground.

Mwa…♡

The scent of her pee, laced with a girl’s fragrance.

“Nii-cha, don’t look…”

“Ah, s-sorry!!”

Heart pounding, I finally step back.

(What am I doing…!)

Reflecting on my actions while turning away, my groin inexplicably swells.

…

“You can turn around now.”

“Okay…”

Maya’s done peeing.

“Why’d you come?”

“I… got worried. Didn’t know you were peeing.”

“Hmm… Worried enough to follow me?”

“Yeah.”

Maybe I was overprotective, but I was consumed with concern for her.

“Fine, I forgive you.”

“Thanks, Maya!”

“But, Nii-cha…?”

“Hm?”

“Why’s your cock so hard?”

(Oh, crap…!)

Relieved at her forgiveness, I forgot to cover my bulge.

“Hey, Nii-cha♪ Why’s your cock so naughty?”

Maya grins mischievously, leaning toward my tented pants.

“Did watching my pee turn you on?♡”

She’s right, but I’m too embarrassed to admit it, stumbling over words.

“N-No… Uh, well…”

“Is Nii-cha a pervert?”

“Ugh…!”

She hits a sore spot. I don’t have a pee fetish—it’s just her shy expression that excited me. Probably.

“Nfu♪ Let’s see what’s going on~”

“Wait…!”

“Don’t move. It’s unfair you saw mine!”

Maya pulls down my pants.

“Wow♡ So hard♪”

“Ugh…”

She smiles gleefully at my cock.

“Got excited watching a girl pee?”

“…It’s because it’s you, Maya. If it wasn’t someone I love, this wouldn’t happen.”

“R-Really~? You love me that much?”

“Yeah. I love and adore you.”

“~~~♡♡♡”

Maya’s cheeks twitch with joy at my words.

“Then… I wanna see yours too. That’ll make us even.”

“Huh???”

I’m baffled by what she means.

“I mean, you pee too, Nii-cha.”

“What…?”

Thus, I end up peeing in front of Maya.

…

“Still not coming out?♡ No need to be shy.”

“Ugh…”

It’s embarrassing to pee in front of my beloved. But that’s not the issue—a hard cock doesn’t pee easily, for some reason.

“Come on♪ Pee~”

Shiko shiko shiko♡

Maya grabs my cock, stroking it with her warm hand.

“Ugh… Maya, stop…”

That makes it even harder to pee.

“Fufu, I was embarrassed too♡ Come on, let it out~♡”

“Gu, uuu…!”

I try to shrink my cock to pee, but her hand keeps stroking, preventing it.

In the quiet forest, only our heavy breaths and the friction of my penis echo.

This bizarre reversal can’t last forever, and the moment arrives.

“Agu!! It’s coming!!”

“Whoa!!”

Pyuu♡ Doku♡ Doku♡

I accidentally leak semen. Trying to pee, I couldn’t resist her hand’s pleasure, unable to stop the rising semen.

“Wow… Wow♪”

Not a full ejaculation, but the semen from my cock’s tip splashes Maya’s face, staining her tanned skin white.

“Nii-cha, this isn’t pee, right?”

“Uah… S-Sorry.”

“Nfufu♪ You’re such a perv, Nii-cha…”

Even so, her hand gently strokes my cock.

(I came without even thinking…)

Still clear-headed, I’m milked of semen—pyuru…♡ pyuru…♡—without my usual force.

“Sorry, Maya…”

“You had white pee stored up, huh♪”

Confused by this unfamiliar sensation, another wave hits.

“Oh no… It’s coming…”

“More, let it out~♪”

“No, not that… Ugh!”

Joro… jobobobobo…

“Wap…♡”

My efforts to pee finally pay off. After white semen, my cock releases yellow liquid.

“Nhaa♡ White pee, now yellow pee?”

“It’s dirty, Maya…”

“No way. Gulp♡ My beloved’s pee isn’t dirty.”

Maya drinks my yellow droplets.

Jororororo… Joro…

“Nku… Nn♡”

Chorororo…

“Haa♡ Pero♪”

“Auu…”

She bathes in and drinks my copious pee.

“Feel better, Nii-cha?”

“Y-Yeah. Thanks, Maya.”

Finding her adorable, I pat her head.

“Ehehe~♪ If you need to pee again, I’ll drink it.”

No, thanks. I don’t have that fetish, so I politely decline.

“There’s a stream nearby. Let’s wash up?”

“Yeah.”

We clean our fluid-soaked bodies and return to Carla at the work site.

“That was a long break, huh…? Fufu,” Carla says.

“Haha… Sorry.”

She’s not mad—her laid-back island attitude contrasts with my Japanese sense of time.

“Let’s finish the rest♪”

“Got it.”

…

In this relaxed island vibe, I’ve come to love this life.

“Haa♡ I love you, Nii-cha♡”

Loving Maya—

“Aan♡ Wonderful♡ Nhaaa~~~n♡”

And Carla—

This island is rich in nature, and we live within it. Lovemaking is part of that nature—when feelings peak, it’s natural to act on them.

Waheide Island is truly a paradise for me.

※

After days of this dreamlike life, a woman visits the house.

“There’s a Japanese person here, yes?”

“Uh, that’s me?”

“Yes, you.”

Wearing what seems like traditional island attire—revealing, adorned with gold—she looks high-status and beautiful.

“Do you need me?”

“Yes. Her Majesty the Queen summons you.”

“Huh?”

I freeze at the sudden news. The country is a democracy led by a president, but my guidebook mentioned it was a kingdom half a century ago.

Royal authority still holds sway, perhaps justifying such forceful actions.

“Is this mandatory? I don’t want to leave this house…”

“What…?”

“No way, Nii-cha…” Maya says.

“You dare defy Her Majesty?” the woman snaps.

“Ugh…”

Her right hand reaches for the sword at her left hip.

“I-I’ll go! No defiance here…”

Sensing danger, I raise my hands in surrender.

(This place is like this…?)

Shivering at the medieval vibe, the woman smirks, satisfied.

“You should’ve done that from the start. Come.”

I’m forcibly taken to the queen’s palace, where I meet—

“Well met, traveler from afar. I welcome you.”

A woman exuding overwhelming authority, the pinnacle of this nation.
