Shut-in StepSister

The pleasant sound of brushing echoed in the bathroom.

Changing into his uniform and finishing breakfast, before leaving the house, there was one last thing to do.

That was brushing teeth, a truly morning-like scene.

“…………”

“…………”

And, it was also commonplace in the Miyoshi household for Yukine to cling tightly to my arm like a koala.

“Yukine.”

“What is it, Nii-san?”

“Actually, it’s kinda hard to brush my teeth with one hand occupied, you know?”

“Then I’ll be your right arm, Nii-san.”

“That’s not the issue here.”

Since she stubbornly refused to let go, I gave up and brushed my teeth with one arm.

Then I grabbed my bag and went to the entrance to put on my loafers.

Finally, Yukine let go of me here.

Yukine was a girl who loved home dearly, and although she had opened up to me like this, she had never left the house since we started living together. Basically, this was just a temporary farewell at the entrance.

“I’m off.”

“Take care, Nii-san.”

“Yeah.”

As I left through the entrance, I waved back at the overwhelmingly adorable Yukine, as usual.

“⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯”

Yukine murmured softly behind me.

But it was so quiet that I couldn’t make out a single word.

“Hm? Did you say something just now?”

“No, nothing. Take care.”

“Yeah, see you later…”

With Yukine’s small smile bidding me farewell, I finally left the house.

Outside, the sun’s rays, characteristic of summer, were already shining down from above.

“(I have a bad feeling about this…)” 

With a strange sweat breaking out, I made my way to school.

After school.

As I was putting study materials for homework into my bag, I felt a tap on my shoulder from behind.

Turning around, there stood the familiar face of that guy, as loud as ever.

“Hey, Miyoshi! Let’s play soccer at the riverside!”

“Who does that kind of stuff in high school?!”

“Tch, boring.”

The dejected guy was my classmate, Shige Narahashi. 

In short, he’s the crazy popular guy.

“What about you, Marimari? Will you play soccer?!”

Narahashi asked as he stood up and slung his bag over his shoulder, addressing Imari.

“Sorry, Narahashi-kun. I have a committee meeting today, so I can’t. I hope you understand.”

“I see… Well, I’ll invite you next time then!”

“Yeah, please do.”

Imari smiled like a saint. 

As always, she was kind to everyone, and, needless to say, her ample chest was impressive.

“…Miyoshi-kun. I think I’ve told you this before, but it’s better to abandon the idea that just looking isn’t a crime, you know? For the one being watched, the perpetrator is almost always guilty.”

Imari glared at me with a sharp look while covering her chest with her arms.

“Wait, wait, wait! Why do you assume I have that mindset?”

“Because otherwise, it’s hard to believe that you’re staring at my chest, Miyoshi-kun. Honestly, if it weren’t for you, I’d dial 110.”

“Hey! I’m not staring that much!”

“No, Miyoshi prefers chests over butts. Especially big ones… he’s probably staring!”

“Don’t encourage him, Narahashi! Go play soccer in the riverbed!”

“Got it, let’s go check out women’s chests at the riverbed to match Miyoshi’s tastes!”

“How did it come to this?”

“Miyoshi-kun… you’re quite frustrated, huh?”

“Is this how rumors get exaggerated?!”

Though it’s just among the three of us for now, if only a part of it were heard by someone else, they’d think I’m a die-hard b**bs enthusiast. 

Gossip is truly terrifying. 

It spreads quickly, and I’d rather not deal with its consequences if possible.

“Seriously, cut me some slack. I don’t stare at Imari’s chest that much. I mean, I only glance occasionally.”

“You’re admitting to staring…”

Imari looks incredulous.

Clearing my throat, I continue, 

“Listen, I just want to say one thing. It’s honestly uncontrollable for a guy to be drawn to Imari’s… captivating chest. It’s like an unconscious force of attraction. It’s the ‘gravity of ample bosoms.'”

“Why am I being lectured on this disgusting topic by you, Miyoshi-kun?”

“Anyway, what I’m trying to say is, I hope you can forgive me a little. I’ll even apologize in advance, sorry.”

“When you’re this shameless, it goes beyond being gross and becomes refreshing.”

“…Hey, that’s gross, isn’t it?”

“Oi Narahashi you bastard.”

Despite being in the same boat as me, Narahashi seems to be supporting Imari now. 

Imari laughed heartily and looked at the clock.

“I should head to the committee meeting soon. See you both tomorrow.”

“Yeah, see you tomorrow.”

“Take care, Marimari!”

We waved goodbye to Imari as she hurried out of the classroom.

“Now then, off to the riverside for me! Later, Miyoshi!”

“See ya.”

Narahashi left too, leaving me behind in the classroom.

“I guess I’ll head home too.”

With no plans for the day, I took my bag and stood up. 

I left the classroom, changed my shoes at the shoe locker, and as I approached the school gate, I noticed some commotion nearby.

“Look look, isn’t that girl super cute?”

“Why is she here? Is she from another school?”

“I wonder if she’s waiting for someone? Maybe her boyfriend?”

“Whoa! She looks like a model or an idol, doesn’t she?!” 

From the murmurs around me, it seemed like an incredibly beautiful girl was at the school gate. 

Intrigued as a guy, I pushed through the crowd to catch a glimpse.

“(Gasp! Th-that’s…!!!)”

Standing alone at the school gate, a girl stroked her hair while bashfully lowering her gaze.

Undoubtedly cute. 

In fact, overwhelmingly so, the cutest I’ve ever seen. 

Of course, the cutest.

As the girl raised her head and noticed me, her face lit up brightly, and she hurried over.

“You’re late… Nii-san.”

It was my shut-in of a stepsister, Yukine, who murmured softly.
