Chillin' on an Uninhabited Island in Another World

Day six continued to pass smoothly.

After finishing our baths, having dinner, and enjoying fruit once more for dessert—the night finally came.

The moment had arrived.

In the room lit by the soft glow of the lantern, my heart felt like it was about to explode from tension. I sat on the edge of the bed, waiting.

"So-kun."

A voice came from outside the door.

"Y-yeah."

When I answered, the door slowly opened, and Chiyu walked in wearing her school uniform.

"Your... school uniform?"

"No boy dislikes a school uniform."

When it comes to hitting my weak spots, no one is better than Chiyu. After all, she seems to know every one of my preferences. Rather than being put off by them, it’s just like her kind self to try and actively fulfill them.

"I-I suppose so."

There was no point in denying it, so I just nodded.

"Then... should we get started?"

Chiyu sat down next to me on the bed and spoke. I felt my mouth go strangely dry. I was clearly that nervous.

But I steeled my resolve and spoke up.

"Chiyu. Before that, there’s something I want to say."

"Since it’s our first time, no 'Energy Up.' It’ll tear."

"I wasn't going to ask for that!"

I couldn't help but snap back with a retort. Luckily, it helped the tension drain from my shoulders.

"Then... what is it?"

Her blue eyes, illuminated by the faint light, looked up at me. I stared straight back into those eyes, so beautiful I felt I could be swallowed by them.

"On the first day... you said we should wait until we got back to Earth. But if we're going to do this, I feel like I should tell you first."

The first day. Back when we were alone in the hut. I had tried to tell her how I felt, but it had been put on hold.

"...!"

She’s my childhood friend; we’ve known each other since kindergarten. With her doll-like beauty, lack of expression, and flat tone, she’s often mistaken for being cold. But in reality, she’s kind, loves jokes, and has a big heart.

"I've loved you since kindergarten, Chiyu."

At my confession, Chiyu’s eyes widened. After a moment, her cheeks flushed, and she smiled.

"I know. Me too."

The painful thumping of my heart, the cold sweat, the numbness in my fingertips, and the burning tension in my face—I felt like it was all finally rewarded.

Without thinking, we leaned in for a kiss. Our lips just barely touched. Yet, that simple act filled my mind with a sense of pure bliss.

Chiyu’s eyes grew misty, reflecting the lantern light like a sky full of stars. In this moment, the girl before me wasn't just my childhood friend anymore—she was my girlfriend.

"Actually, I've loved you longer. Since I was born."

"Wait, we only met in kindergarten."

"Fate."

"I... I see. Well, if you say so, maybe it is."

It would be boorish of me to say I didn't believe in such things.

As we shared a few more light pecks, our hands gradually began to wander over each other's bodies. I wrapped my arms around her back as our kissing grew more intense, my hands roaming over her hips and thighs. Chiyu skillfully unbuttoned my uniform, trailing her lips down my neck and chest.

"Ngh... So-kun, is your body... firmer?" she asked wonderingly.

"Ah, you noticed? It’s been like that since after the event..."

We didn't stop touching as we continued to talk.

"No matter how much you moved, you shouldn't have become 'lean and toned' that quickly."

"I wouldn't call myself muscular, but..."

My average build had changed; the soft spots were gone, and I could see the start of some muscle. I’d taken the first step toward a lean, athletic physique.

"...Ah."

"What is it?"

"Was it because of 'Strength Up'?"

Her words made perfect sense to me.

"Ah... that’s probably it."

While under her buffing magic, I’d practiced running alongside Mashiro. On top of that, during the event, I was running constantly while receiving continuous buffs and healing. The sheer volume of exercise was astronomical.

In reality, while it let me move fast, it didn't increase my actual stamina, so it had been agonizingly difficult. I’d just been using healing magic to forcibly repair the pain and exhaustion so I could keep moving. Because I’d pushed my body so hard, it had been tempered.

"A 'Strength Up' workout?"

"If that’s the case, I should probably keep doing it. On an island like this, it’s best to train our natural physical abilities as much as possible."

Plus, we had more than enough food to replenish all the energy I burned.

"If your stomach ends up like a bar ✪ Nоvеlіgһt ✪ (Official version) of chocolate, you'll become even more popular."

"No way... the current number is already too much, that wouldn't happen..."

"There are twenty-three girls in our class. The number could increase."

How does she remember that...? All I remember is that for some reason, the girls in our class are all incredibly well-endowed. And among them, with the exception of the assistant homeroom teacher, Chiyu is the biggest.

"Chiyu, it’s not like I’m trying to build a harem with the girls in our class, you know?"

"I know. But actually, things are going quite well."

"Well, that’s true, but..."

I’m technically the party leader, but it’s largely thanks to Chiyu’s behind-the-scenes work and everyone’s understanding.

"Besides, by now, I’m sure you’ve come to like the other girls too."

"Ugh..."

After everything we'd been through, it was only natural to develop feelings. They were all charming, wonderful girls.

"That’s fine. Tell the others you like them, too."

It did weigh on my conscience that I couldn't return the affection they showed me.

"Are you really okay with that, Chiyu?"

"Mhm. I like them all, too. And... it’s already decided that So-kun will be by my side in the end."

"...Haha. Right, because it’s fate."

"Exactly."

Chiyu and I kissed again, and I gently pushed her back onto the bed. As I undid the top half of her uniform buttons, her twin peaks—unburdened by a bra—were exposed.

As we hungrily shared our lips, Chiyu’s small hand brushed against my trousers. I reached my right hand down toward her lower belly... and realized something.

"You... you aren't wearing anything underneath, either?"

"Mwah... ngh... did you want to be the one to take them off?"

"Let's... save that for next time."

"Understood."

We remained entwined, stoking each other's excitement, and the wet sounds from Chiyu’s private area grew louder. When I pulled my hand away, my fingers were glistening.

"So-kun... I think... it’s time."

Her face was bright red. It was incredibly endearing.

"O-okay. Then, let's, uh, begin..."

"Mhm. Give me the thing I wanted most."

Why did she have to say it in such a provocative way? No, she was probably doing it just to fire me up.

I hurriedly lowered my trousers, and to cover the rod pointing toward the ceiling...

I Itemized a Condom into my hand.
