Gloomy Outside, Gal Inside ~Dealing with My Step-Sister Isn't Easy~ - Chapter 02: Stand Proud, My Sister

Chapter 02: Stand Proud, My Sister

“Hey, Nii-san?” 

“What is it, Miu?” 

“You seem a bit tense.”

“…”

My sister can be cruel…

Today is a holiday, and I was awakened by Miu and dragged outside… but my mind is focused on one thing.

“You’re so tense. It’s like a certain part of a man becomes a certain way in the morning.”

“Enough! Shut up!”

“Eep!”

I moved slightly away from her with a little force.

She mentioned the morning part or the moaning voice when she grabbed me by arm… coupled with her appearance, it’s a struggle to hold back something within me that’s about to explode.

No… Miu is very perverted… I mean, the fact that she can have this kind of conversation with her brother, and even press her ample bosom against him, is perverted.

But she’s my sister! That’s why… that’s why she’s a damn brat!!

“Calling me a perverted stepsister is so mean… Well, but Nii-san, do you think I’m erotic? Haha~n?”

“…”

Swaying her body gently, Miu looks up at me with a sly smile.

Since she’s shorter than me, when she looks up at me like this, her ample cleavage is naturally on full display.

Off-shoulder… I’m not good at explaining women’s fashion, but today Miu is wearing a top that reveals her shoulders, paired with hot pants that expose a fair amount of skin.

(…It’s no wonder that passing men are staring at her.)

As for me, I think she’s cute even in her usual appearance.

However, during private moments like this when there are no school friends or acquaintances around, she dresses so flashy. It’s as if she’s suppressing her own charm in her everyday self.

But once she unleashes that charm, revealing her hidden beauty and outstanding figure… well, this is what she becomes.

(There’s no harm in it… In fact, I don’t mind Miu looking like this myself.)

It’s all because of the influence of my friends who encouraged the “little sister gal” idea… sigh.

“Come on, Nii-san. Don’t look so down. Let’s have fun. It’s a date with your little sister, okay?”

“…Yeah, you’re right. But Miu.”

“Hmm?”

“Well… Are you really having fun going on a date with someone like me?”

When I asked that, Miu’s eyes widened in surprise.

I have an average face like Dad, but Miu takes after Mom and is an incredibly beautiful girl.

Even though I rescued her from bullying and tried my best to take care of her emotionally… It makes me happy that she adores me, but I can’t help but wonder if she truly enjoys being with someone like me.

“Geez! Were you really worried about that? If you thought I didn’t look happy with you, even a little bit, then you’re incredibly dense, Nii-san! It’s unthinkable!”

“O-Okay, I got it… Stop hitting me!”

“No, I’ll give you another hundred smacks.”

“You’re so merciless!?”

If we have exchanges like this in public, we naturally attract attention.

Older folks give us amused smiles, but younger men or guys around the same age send jealous looks… or perhaps looks fueled by jealousy. It’s quite a spectacle.

“Oh, Miu.”

“Huh?”

Suddenly, I pulled Miu closer to me.

Startled, Miu looked up at me, her face nestled against my chest. But it’s not like I did it just because I wanted to embrace my sister.

“Oops, sorry for that, missy.”

“It’s fine~”

It was because an old man with a cart passed by.

He had stacked the items on the cart quite high, and I thought he might not be able to see Miu, so I ended up pulling her closer, as expected.

“Oh… is that why?”

“Yeah. Sorry… I guess I could have just pulled you lightly instead of hugging you.”

I quickly let go of Miu.

Well, I know that she won’t get mad about something like this, but I still thought it was a bit excessive to embrace her.

“It’s okay. Thanks, Nii-san ♪”

“…Yeah.”

…Well, if I got to see her cute smile, then it’s all good.

After that, we enjoyed our date, just spending time together as our hearts desired. And as a short break, we ended up at a bookstore.

“I’ll be looking at the fashion magazines over there~”

“Sure thing~”

Temporarily parting with Miu, I began checking the manga and light novels I was interested in reading.

I have a habit of buying too many books, and in the end, I often don’t get around to reading them all, but that’s just who I am.

As I picked up a few books and was about to head to the cashier, I found myself in a zone filled with rows of erotic manga.

“…Ah.”

As I gazed intently, I found a certain manga.

It was a book that my friend lent me, saying it was not only incredibly erotic but also entertaining—a manga depicting the lovey-dovey and erotic daily life with a little sister gal.

I naturally picked up that book and muttered to myself.

“This thing has corrupted my fetish…”

Yeah, that’s right… Because of this, my fetish has become twisted.

When I say my fetish is twisted, it doesn’t mean I want to engage in specific play or anything like that. It’s more about my preferences for women… Well, it hasn’t infiltrated reality, but it has become twisted enough that if I come across it in online advertisements, I might click on it.

“Sister gal… Hmm, there’s a unique appeal to this.”

Yes, I’ve become obsessed with sister gal stories and any works featuring gals.

When I say gals, I don’t mean black gals or anything like that. It’s more like light-hearted, cute gals. That’s what they are.

“Whether it’s a gal who’s kind to otakus or a gal who opens her heart only to the protagonist… The little sister in this story is truly adorable.”

In this story, although the little sister is promiscuous, she realizes the importance of something precious by crossing a certain line with the protagonist, and the protagonist starts to cherish her. 

The manga depicts their lovey-dovey relationship to the point where the past depiction of the little sister engaging in compensated dating is overshadowed and becomes irrelevant.

“Oh, this manga is also in Nii-san’s room, right?”

“Yeah. This manga is super interesting! The little sister is both sexy and cute… It’s just full of lovey-dovey sweetness… Ha!?”

Oh no… I slowly turned my gaze towards the voice, like a broken tin man.

Miu was looking at me with a smirk on her face, and her expression clearly said, “Oho, this is interesting,” as if she was about to tease me mercilessly.

(…Wait, they kinda look similar…?)

For a brief moment, I truly thought so.

The little sister gal, the heroine of this manga, and the Miu in front of me seemed somehow alike or similar.

Of course, both of them are incredibly cute, have outstanding figures, and exude an erotic aura… But it’s not just that; their vibes also seem alike…

“Nii-san? Are you thinking that the heroine in this manga and I look alike?”

“…N-no, I’m not!”

I quickly returned the book to the shelf and picked up the books I intended to buy, heading towards the register.

While I was at the cashier, a male store clerk kept stealing glances at Miu… I couldn’t help but feel irritated, thinking, “Do your job properly,” and at the same time, it annoyed me as if he was looking at her in a strange way.

After leaving the bookstore, I remembered something and asked Miu.

“Hey, Miu.”

“What?”

“That book… It’s kind of erotic, or rather, rated R18… Did you read it?”

“Yeah. Well, it’s like R18 is a word that doesn’t exist for young people nowadays, right?”

That’s certainly true… But as someone whose stepsister read an erotic book featuring a sister, I’m feeling an intense sense of shame… I want to die.

“…”

“What’s… wrong?”

Miu stopped walking, so I followed her gaze to see what caught her attention.

There, I saw a face that I remembered… A flashy girl leading a group, who was once the ringleader of bullying against Miu.

Even though we go to different high schools, in a large city like this, it’s possible to encounter such people.

“I-It’s okay. For me, she’s already…”

Without saying anything, I hugged Miu’s shoulder.

“Nii-san…?”

“That girl doesn’t know the current Miu, right? Let’s walk proudly by her side. I want to show her that my sister is so cute and such a good girl, much better than a mean-spirited girl like her.”

“…Mou. Didn’t you say that I’m unrecognizable now?”

“I said that. But walking beside me, Miu is still my little sister.”

“That’s right… Ahaha, that’s right!”

We’re not going to engage with her.

Miu and I walked confidently in front of her… Maybe she recognized my face, but she was looking at Miu more.

In my heart, I laughed at her with a thought of, “What’s the matter? Jealous of Miu, who shines brighter than yourself?”

“Nii-san… You’re cool.”

“…Yeah. I’m your big brother, after all.”

“Yeah♪”

…At times like this, it’s a given that I would be overwhelmed by my sister’s cuteness.

[Postscript] 

She has become the heroine that perfectly matches my taste. 

I would be delighted if readers find her adorable!
