Chillin' on an Uninhabited Island in Another World

I never expected the word harem to come out of the mouth of our overly serious Class Rep.

Minori, who used to be the one scolding people for improper relationships, was now standing right in front of me, close enough that I could feel her warmth.

“Minori... are you really sure about this...?”

“Y-yes. We already talked it over among the girls, and we’ve all agreed.

Besides, improper relationships are supposed to be ‘actions that interfere with raising boys and girls in a healthy way,’ but... in peaceful Japan that might matter. In a deserted island environment like this, we don’t have the luxury of talking about proper upbringing.”

When the time and place change, the rules that matter change too.

When in Rome, do as the Romans do.

It sounds obvious when you put it that way, but not many people can switch off rules they’ve lived by their whole life.

“I... see.”

“The central figure of this group is you, Kuno.

Even if you did nothing, you wouldn’t treat any of us differently.

But relying on your kindness alone wouldn’t be healthy.”

Shion had said something similar before.

In her case, it was also because her Lie-Detection Ability hadn’t really been useful yet... but still.

Both of them felt that taking too much from me without giving anything back was what wasn’t healthy.

And because of that, they’d come to accept the idea of this... arrangement.

“You contribute plenty with magic and knowledge, Minori.”

At my words, Minori’s expression faltered.

“S-so... I’m not attractive enough...?”

Realizing I’d made her misunderstand, I shook my head hard.

“That’s not it at all.

I just don’t want someone as serious as you to make a choice you’ll regret if we ever go back to Earth.”

Whether someone does something willingly or because they feel cornered...

even if the act is the same, it means something completely different.

“I won’t regret it.

I... actually liked you from the start, Kuno.”

“...Really?”

“D-don’t laugh, okay...?”

She hesitated, then began to tell the story.

It happened one day after class.

The teacher didn’t feel like carrying the collected notebooks to the staff room, so he dumped the job on the Class Rep as usual.

Normally, Minori and the vice-rep would split the work.

But that day, the vice-rep was absent.

The teacher didn’t notice and left the classroom anyway.

Forty notebooks couldn’t be carried in one trip.

But Minori, who wasn’t exactly popular in class, couldn’t bring herself to ask anyone for help.

She’d decided she’d just make two trips herself.

“But... you came up and offered to help me, Kuno.”

“...Oh. Yeah, I remember that.”

“There were some people watching, knowing the vice-rep was absent, just waiting to see what I would do.

I couldn’t ask anyone... and then you spoke to me.

I was really happy.”

“Maybe I just helped because you’re pretty.”

“Hehe. No.

After that, I started watching you more, and I realized... you help people naturally, without thinking about it.”

So that’s why Minori trusted me so quickly after the transfer, even after having a bad experience with those two guys earlier.

“...Then you’re really sure?”

“Y-yes.

If it’s with you... even... indecent things... don’t feel unpleasant.”

Hearing that, there was no way I could hold back.

I took Minori’s hand and led her toward the shade of a nearby tree.

“Sorry. I don’t think I can wait until we get back.”

“—! I-it’s fine.

At home I’d probably be too worried about the others coming back to focus anyway...”

We stopped beneath the big tree and looked at each other.

Minori closed her eyes, like she was waiting.

I leaned in and gently pressed my lips to hers.

“...Mm.

I... I really did it... with you, Kuno...”

The fact that Minori — who had always been strict with herself and everyone else — was accepting me like this made my heart race, and I ended up kissing her again.

She looked surprised, but didn’t resist.

Our breathing grew heavier, our bodies pressing closer together.

After a moment, she opened her eyes.

Up close, her gaze was hazy, flushed with heat — nothing like her usual sharp, composed expression.

The thought that I was the one making her look like that only made me more excited.

“K-Kuno... something is... pressing against my stomach...”

“Sorry. You’re just... too attractive, Minori.”

Her eyes dropped.

She noticed the obvious bulge in my pants... and swallowed.

“You’re... aroused... because of me...?”

She was probably just repeating knowledge she’d read somewhere, but hearing her say it out loud made my heart pound.

“...Yeah.”

“Don’t apologize, Kuno.

If you’d like... may I help you... release?”

“...Please.”

Minori knelt in front of me, her face red as she started undoing my belt.

She pulled my pants down—

...and then froze for a second, staring.

“This... is...”

She looked flustered, clearly unsure what to call it, searching for the right word.

“...S-sorry. I don’t know the proper term...”

“That’s fine. You don’t have to say anything.”

“...Then... I’ll just... help you.”

She hesitated, then gently reached out.

Her hands wrapped around me carefully, as if she was afraid of doing something wrong.

“It’s... warm... and so hard...”

“M-Minori... you can move...”

“R-right. To create pleasure... stimulation is necessary...”

Her hands started to move, slowly, awkward at first.

Careful, deliberate motions — the same hands that were usually holding a mechanical pencil, now trying their best to make me feel good.

Gradually, the movement became smoother, faster, as if she was remembering what she’d been told.

“...Minori... did Shion teach you...?”

“Y-yes... she told me... what you prefer... in case something like this happened...

Is... my hand... not good enough...?”

“It’s fine. Really.”

“Th-then... does it feel good?”

“...Yeah...”

When I nodded, she looked relieved.

“I’m glad...

If there’s anything you want, tell me.

I want to make you feel good...”

Her curiosity mixed with embarrassment, and the more she realized she was doing it right, the more her expression softened.

It was nothing like her usual serious face.

It was warm, flushed... and dangerously cute.

That alone was enough to push me close to the edge.

“Minori... I’m... close...”

“Ah—wait... I forgot to—”

My body tensed, and the pleasure hit all at once.

The sensation rushed through me, making my vision flicker as my legs trembled.

After it faded, I looked down at her.

Minori looked pale, like she’d just made a terrible mistake.

“M-Minori...?”

“I-I’m sorry, Kuno...

I skipped a step... I got carried away...”

“A step?”

“I was told... I should prepare properly...

and I forgot...

I wanted to do it right... like the others...”

She looked like she was about to cry.

Minori had always been like this —

when she failed at something, she blamed herself more than anyone else.

“Minori. It’s fine.

It felt really good.”

“N-no... that’s not enough...

C-can you give me another chance...?

Next time I’ll do it properly...

I want to do it as well as the others...

So please... don’t be disappointed in me...”

She clung to me, her voice trembling.

“I’m not disappointed.

Not even a little.”

“B-but...”

“If you want to try again, I’d be happy.

Not because you need to make up for anything.

Just... because the first time was already really good.”

“...Really...?”

“Yeah.

Just thinking about you doing it again...”

Even though I’d just finished, my body was already reacting again.

Minori’s eyes widened in surprise.

“You’re... already...?”

“...So... can I ask again?”

“...Yes. Leave it to me.”

She took a breath, gathering her resolve.

“...This time... I’ll do it properly.”

Under the shade of the tree,

Minori tried again — far more confidently than before.

And by the time she was done,

I was completely exhausted...

and she looked just as flushed as I felt.
