Gloomy Outside, Gal Inside ~Dealing with My Step-Sister Isn't Easy~ - Chapter 11: After-School Shopping Date

Chapter 11: After-School Shopping Date

“…?”

My body feels heavy… that was my sensation upon waking up.

I felt a sensation as if something was sitting on me, and I desperately tried to move my drowsy head to think about what it could be.

As a result, I lifted the blanket.

“Good morning, Nii-san♪”

“…”

I covered the cute smile that emerged from under the blanket and lifted it again to make sure of that presence.

“Good morning♪”

“…”

I covered the blanket once more, thinking that I might be mistaken, and checked the time on the clock.

It was still 6:30 in the morning, so I still had a little time to sleep… Should I indulge in a little more sleep? As soon as I closed my eyes, Miu crawled out from under the blanket, showing her face.

“Hey~! Can’t you at least say good morning to your adorable little sister!?”

“…Good morning.”

“Yay♪”

Miu, who showed her face, straddled my waist and looked down at me with her cheeks slightly flushed.

Does she understand how dangerous it is for a guy to wake up in the morning?… But I felt relieved that I hadn’t touched her body, and I wondered if it had been okay while I was sleeping.

“Hey, Miu…”

“Hmm?”

“…No, it’s nothing.”

“Really?”

Unlike me, who was still in my pajamas, Miu was already dressed in her school uniform and fully prepared.

She wasn’t wearing glasses, and her messy hair was as usual… I was a bit worried that her uniform might get wrinkled, but please let me sleep a little longer.

“Can you let me sleep for another 10 minutes?”

“Sure. Then like this—”

Miu leaned forward while still straddling me.

Her ample chest pressed and changed shape against my chest, and Miu’s face came dangerously close to mine.

“Heheh…”

“What’s the matter?”

“Nii-san, you know? Lately, you’ve stopped trying to push me away.”

Miu said that with a smirk, and I pondered over it and confirmed it myself.

Since our parents were gone, things had changed… Not that she had become a different person, but the distance between us had suddenly become closer, and it made my heart race.

It happened when we took a bath together, and even now, when she suggested sleeping together… It even felt tiring to refuse her advances, 

“I’ve given up.”

“Huh?”

“…Without our parents here, there’s no one to stop you, right, Miu? Even if I tried to stop you… I don’t want to see that sad look on your face every time. And… I don’t dislike it either.”

“…”

I said that while patting her head gently.

Certainly, there might be older brothers who would find it annoying to be treated like this, and there might be those who would go as far as to hate it… But that’s not me.

Maybe it’s just that I’m simply indulgent with Miu and let her have her way, but it’s also true that I find enjoyment in this interaction.

“There are limits… There are limits, you know? But I’ve never found interacting with you annoying, not even once… probably.”

“Mou! Just say it until the end!”

“Fine, fine. Alright, wake me up in 10 minutes, Miu.”

“…Got it.”

And so, after precisely 10 minutes had passed, Miu called out to me, and I woke up.

Miu left the room ahead of me, and as I washed my face and changed my clothes, I had something to think about.

“…I guess my mental fortitude has been honed to the max, huh?”

That’s right.

Ever since it became just the two of us in this house, Miu’s behavior has clearly changed, and she constantly does things that recreate my beloved erotic little sister gal character.

It’s because there’s no stopping her… But if my willpower were weak, I wouldn’t be able to handle it.

“…”

After finishing changing, I silently picked up that manga.

The ultimate little sister gal erotic manga that captivated me in an instant and twisted my fetish… with pranks on me while I’m sleeping, or giving me sweet stimulation when I wake up in the morning… as our hearts gradually grow closer, she invites me with a variety of cosplay, and it’s certainly erotic, but above all, it’s precious.

“Oh, right, it’s not something I should read before going to school.”

I feel like my lower half is about to get excited!

As I left the room and headed towards the living room, the tempting aroma of a delicious breakfast welcomed me and stimulated my empty stomach.

“Let’s eat.”

“Let’s eat♪”

I want to help too, and I wouldn’t mind taking turns, but Miu stubbornly refuses.

Because of that, I generally leave meals to Miu, except when she’s extremely busy or has something else to do… Well, I heard from Mom that Miu is capable, but actually experiencing it like this… Yeah, this girl is really skilled at cooking, from simple dishes to elaborate ones.

“What’s wrong? You’re nodding so much.”

“I was just thinking that the food you make, Miu, is delicious. I really think you’ll make a great wife.”

“Heheh… Thank you, Nii-san. So, um…”

“Yeah?”

“Would you marry me, Nii-san?”

“!?”

I accidentally shook the table.

If I had been drinking something, it would have been a disaster. While thinking about that, I looked at her, who continued to smile, waiting for my answer… And surprisingly, I answered without much hesitation.

“We’re siblings… well, technically step-siblings, so there shouldn’t be any issues. But yeah… it seems like it would be quite challenging if I were to marry Miu… but also fun every day.”

“Hmm, you’re answering honestly, huh?”

“Well, it doesn’t cost anything to say it.”

“…Mu!”

“Hey, don’t kick me!”

That’s what happens when you honestly answer someone… But I’m not lying.

From the current situation, I can’t imagine having such thoughts even the slightest bit, but to me, Miu is an incredibly precious sister… which means, she’s also a precious girl, I think.

So there is a possibility that this thinking could change… Well, maybe it’s impossible.

“…”

However… If I continue to be stimulated by Miu’s exciting and sweet temptations, like today, there’s a danger of awakening the dormant beast within me…!!

With that thought, I shook my head vigorously.

She’s my dear sister! A cute and precious sister! A sister to protect…!!

“Nii-san.”

“Hya!”

“Hya…? If it’s okay, would you like to go shopping together after school today? The fridge is surprisingly empty.”

“O-okay, I’ll be your shopping assistant.”

If it’s being a shopping assistant, I’ll gladly take on the role.

With that plan set for after school, time passed, and it was finally time to leave school.

“Why?”

“Sorry for the wait, Nii-san♪”

On weekdays, Miu shouldn’t typically dress up to go out, but when she returned home after school and finished getting ready, she transformed into a gal. 

With silky twin tails and revealing clothing that never failed to make my heart race, she looked absolutely stunning.

“Well, well, isn’t it fine? Occasionally, I want to spend weekday evenings with Nii-san while dressed like this, you know?”

~Meow?~

Cocoa, who came to see us off, seemed to synchronize with my state of mind and shook her head as well.

Now, I was going outside with Miu, who was unusually cheerful. However, as expected, when we entered the bustling downtown area where the crowd was significantly denser, Miu truly attracted attention.

Not only her voluptuous breasts, but her thighs were also quite exposed… Yet, it seems that she only sees her appearance as a fashion statement and doesn’t really mind, although she looks somewhat uncomfortable.

(I can’t leave her alone…)

If I were to leave Miu’s side, it’s likely that she would constantly be approached by guys trying to hit on her.

There would definitely be sleazy guys trying to pick her up with ulterior motives… It would be a solution if she didn’t dress like this, but since I don’t dislike it myself, I can’t assertively tell her not to… Well, it’s a feast for the eyes, seriously.

While enjoying the after-school date disguised as shopping with Miu, it happened.

“Isn’t that…”

Walking ahead of us was the junior boy we had previously encountered in the staff room… the one who was on duty with Miu.

As I watched him walk with a slight sense of unease, I couldn’t help but think that he should carry himself with a bit more confidence.

While gazing at him in that manner, our gazes crossed—and he glanced at Miu, who was standing next to me, for a moment, his nose twitching… It seems he’s just like any other guy, of course.
