That night.

I lay on my back on the bed, staring absentmindedly at the ceiling.

“Seriously… what was that even about?”

Today was a day off.

I went out shopping by myself for a change of pace.

And just when I thought I’d gotten hit on for the first time in a while, the one who stepped in to help was Fukase-kun of all people.

He’s so hard to ignore that I ended up memorizing his name, despite having no interest in him.

Lately, he really has been standing out.

I have no idea what he’s after, but I’ve always felt his gaze on me.

You can tell when someone’s looking at you surprisingly quickly.

A guy’s stare is usually something you can just ignore—or at least, that’s what I’d always thought.

But no matter how much I tried to look away, he alone kept slipping into my field of view.

And then there was… my chest, where he touched me.

During the physical exam, he ended up touching a place I’d never even let another girl touch.

“Haa… I was planning to get mad at him at the café, but I completely missed my chance.”

I had so many things I wanted to say, but they all blew right out of my head.

I can’t forget it.

Back then… there was definitely that ‘thing’ between his legs.

There were a lot of girls there.

What did they all think when they saw it? 

“If girls have genitals, then boys have genitals too… right…?”

That thick and hard-looking thing with a slightly grotesque appearance. 

That was Fukase-kun’s genitals.

If he were always like that, there’s no way it wouldn’t be noticeable even through his clothes.

Then why did it end up like that…?

“…No, no. That’s impossible. There’s no way.”

Even girls have parts that get hard when stimulated.

But with Fukase-kun… it seemed to react to something specific. 

“I-I shouldn’t be thinking about that right now!” 

I covered my face with both hands.

I’m not some perverted girl… Well, I have done it by myself before, but still.

“—Are boys really… that strong?”

The strength in his arm when he pulled me away from the pickup attempt.

It was shockingly powerful.

I’m used to getting hit on.

But the kind who get forceful and make it hard to escape are rare.

So it’s true that he saved me.

“And he didn’t even back down to those aggressive gyaru…”

Was Fukase-kun always that tall?

There are girls who are taller than him, sure—but in that moment, he just looked… unusually large.

“Haa… I even exchanged contact info with him… what am I doing…? Getting close to a boy should be completely out of the question for me.”

His eyes when we were sitting across from each other at the café.

They looked like he was staring at something far, far away.

Lonely eyes, like he was searching for something deep inside me.

“What should I do from now on…?” 

I reached out toward a question with no answer.

Back in middle school, I’d never once let myself be led around by someone else—and yet now, I was completely being swept along by him.

◇◇◇ 

The weekend ended, and Monday arrived.

Even though I’d exchanged contact info with Asuka, I still hadn’t sent her a single message.

I’d told her she didn’t need to reply, but I couldn’t think of what to send at all.

Back in my original world, we’d exchanged trivial messages like it was nothing, but this was different now.

If I were going to send something, I wanted it to be a message Asuka might actually respond to.

When I entered the classroom, Asuka was already seated.

Normally, just seeing that sight would make my chest tighten—but today was different.

That small step of actually having a proper conversation with her had made my heart feel so much lighter.

“…Good morning, Asuka.”

I sat in the back seat to avoid drawing attention and softly called out. 

I sat down in the seat behind her and spoke softly so no one around us would notice.

“…………”

There was no reply.

Oh, right—I’d called her by her given name again. 

For some reason, calling her by her surname just felt wrong.

I thought it can’t be helped when— 

“…………Morning.”

“—!?”

A voice so quiet I almost missed it. 

But I definitely heard it.

Asuka returned my greeting.

In that instant, my chest nearly exploded with joy.

An unbearable wave of bliss that made me want to shout.

“Ah, Kazuto-kun, good morning.”

“Good morning, Aoi!!!” 

“W-what’s with that energy!?”

When Aoi greeted me, I couldn’t help replying at the top of my lungs like an idiot.

I couldn’t direct all this uncontrollable happiness at Asuka, so instead I dumped every bit of it onto. 

◇◇◇ 

“So… today let’s talk about something different from last week.” 

After school, I brought Aoi and Kokonoe back to my place and continued my lectures about the original world and about men.

“Excited…!” 

“Ohhh…!”

The two of them sat at the table, their expectations swelling as their eyes shone.

Last time, the topic had been the male genitalia.

Erections, semen, masturbation—it was entirely that kind of topic.

“Today, I’ll talk a bit about myself first, then we’ll move on to sexual intercourse between men and women.”

“Fukase-kun’s story…”

“I’m curious…!”

I’d already explained that I came from another world, but I hadn’t gone into detail about what kind of life I’d lived there.

If I wanted them to understand me, they needed to know that part too.

“To put it simply, I was just an ordinary guy in my original world. Though if you go by this world’s standards, I’d probably count as abnormal. I had a lot of male friends, and there were more boys than girls in my class.”

“A classroom with lots of boys… I can’t even imagine that.”

Of course.

In this world, men barely exist in classrooms at all.

“And I was on the soccer team back in middle school.”

“Oh, right. You mentioned that before.”

Aoi murmured, as if he’d just remembered.

“I played in matches too. We weren’t some powerhouse team or anything, but I took it seriously. The muscles in my legs now are basically a leftover from that.”

“That’s true… Fukase-kun, your leg muscles really are impressive.”

They’re the result of playing soccer.

My upper body isn’t anything special, but my legs are something I take pride in.

“In my old world, men naturally built muscle more easily than women. That’s why my training actually showed results. But in this world, muscular men are basically unheard of—most are short, and they look more like girls.”

“That’s true… I think a lot of people besides me probably found Fukase-kun strange in that sense too.”

“That’s exactly me…”

If Aoi agrees, then that pretty much confirms it.

“Yeah. Men as a whole are completely different from the world I came from. There are tons of manga and games with male protagonists, and I grew up reading and playing that kind of stuff.”

“That sounds interesting…!”

“And it’s the same with what I’m about to talk about—sex between men and women. There are countless erotic manga and videos featuring men and women together. …But this world has nothing! There’s literally nothing! It’s absolute crap! How am I supposed to get off like this!?”

“K-Kazuto-kun!?”

I checked them not long after I was transported here.

There really is no material. Nothing to use as fuel. I haven’t been able to get off at all.

Which is why, with Kokonoe’s mouth—no, stop it, calm down. I have Asuka—

“Is something wrong?”

“No, it’s nothing. Let’s get back on track. We were talking about sex. I don’t have any experience, so this is all just knowledge.”

At the very least, I have the basics.

So I’ll stick to that.

“I already explained the male genitalia before. You probably know that it gets inserted into the female genitalia, but… before that, there’s foreplay.”

“Foreplay?”

“You don’t know about that, Aoi? What about you, Kokonoe?”

“Uh… um… j-just a little…?”

I knew it.

Someone like her was usually a closet pervert.

And in her case… that really was true.

“Men make women feel good, and women make men feel good. Kissing, touching places that feel good, licking… and the same goes for each other’s genitals…”

Then she suddenly murmured.

“S-so after all… what I did… it wasn’t wrong, was it… ah—”

“Ah…”

My eyes met Kokonoe’s.

Our faces turned red, and the air instantly turned awkward.

Meanwhile, Aoi’s eyes sparkled with curiosity, despite not fully understanding what was happening.

“So you insert the male’s genitals into the girl’s genitals, right? What do you do after you put it in?”

“Well… in missionary position, the male moves his hips back and forth. If the female’s on top, she bounces up and down… probably.”

“Oooh…………”

Aoi looked at me with sparkling eyes—and then, for some reason, he turned that same gaze toward Kokonoe as well.

“Le-le-le—!”

“Huh?” 

“L-let’s do it!!”

“W-what do you mean!?”

Aoi’s eyes brimmed with expectation.

Kokonoe’s aroused gaze. 

—No. There’s no way I’m doing that!!!!
