Gloomy Outside, Gal Inside ~Dealing with My Step-Sister Isn't Easy~ - Chapter 12: Showmanship

Chapter 12: Showmanship

That junior boy… I think his name was Tomita.

It’s the first time we’ve met outside like this, and it’s probably the first time he’s seen Miu transformed into this flashy appearance.

It’s evident from how he’s staring at Miu, completely absorbed.

“…Hello, Nii-san.”

“Ah.”

Hey, I don’t want this guy calling me Nii-san…

I have no intention of talking to him, and there’s no need for Miu to reveal her true self in this situation… If that’s the case, we wanted to enjoy shopping without interacting with him… Well, now that he has approached us, ignoring him would be rude.

“…”

Miu standing next to me remains silent.

Perhaps she’s thinking that our shopping time was interrupted, or maybe she just encountered someone troublesome.

“Um… and who might you be?”

“…”

Now, how should I respond?

We have met the schoolmates in passing before, but no one has approached me like he did… Well, it’s probably because I’m usually so inconspicuous.

Although I haven’t miraculously encountered Toshinobu, Rikiya, or Shinozaki-san either… Well, it doesn’t matter now; I need to focus on the situation at hand.

(Only I know that this transformed Miu is still Miu… It’s what she desires. So, what I should do is…)

We’re walking close together like this.

Considering that I probably won’t have many opportunities to talk to Tomita in the future, I decided to answer like this, intending to apologize to Miu later.

“Quite pretty, isn’t she? She’s my precious girl.”

I said, placing my hand on Miu’s shoulder.

Tomita’s eyes widened, and then he stared at me as if he doubted my words… Isn’t that quite rude?

Nevertheless, rather than claiming that Miu is my girlfriend, which would be a lie, expressing that she is my precious girl is a truthful statement that emerged from the depths of my heart.

“Nii-san… cough!”

Miu seemed momentarily surprised, but she quickly understood my intention.

We wanted to resume shopping quickly and cut the conversation with Tomita short, moving ahead.

However… it seems like Miu came up with something.

After smirking, she leaned closer, hugging my arm, and spoke.

“Is this person Ayato-san’s friend? Or maybe a junior?”

Miu…?

I tilted my head at her unusual behavior, but there’s no way she would understand my intention while I’m unaware of hers.

It’s only natural, and it seems that here, the setting of us being siblings is temporarily abandoned.

So, I decided to follow Miu’s lead and proceed with the conversation as a relationship between a boy and a girl who are not siblings.

“He’s a junior. Although to me, we only met for the first time the other day…”

“Yeah, that’s right…”

“Hmm?”

…But still, it’s amazing.

Aside from when she’s at home, Miu, who is always outside, changes her tone of voice and even her appearance… and she really functions as a different person.

Tomita clearly doesn’t recognize Miu as Miu, and he seems to be struggling to maintain a composed expression, as if he’s seeing her as just a sexy woman.

“You have the face of a virgin, don’t you?♪”

“Wha?!”

Tomita’s face turned bright red at Miu’s words.

Well, those words hit me hard too… Yes, I’ve never had a girlfriend in my entire life, and of course, I haven’t had any sexual experiences! 

How could I?

Miu chuckled, but she seemed to have noticed the tension in my hand as I held her shoulder, and she finally realized that she had said something that hit me as well… She playfully stuck out her tongue.

…What? I knew you were cute.

“But if you say that, then you…”

Well, I knew he would say that!

Yes, I’m a virgin too, you damn bastard… Oops, as I shed tears of frustration in my heart, I reflexively nodded—just when that happened, Miu quickly grabbed my hand, holding it tightly and pressed it against her own chest.

“Go ahead, grope them as if showing off.”

With a smooth motion, she leaned closer and whispered in a volume that Tomita couldn’t hear.

Not only did my heart jump at the suddenness of her actions, but my face also instantly turned hot… Miu continued to speak while looking at Tomita.

“This is Ayato-san, who dotes on me like this. We’re already on a different level, you know?”

“…”

Tomita frowned at Miu’s provocation but looked down as if he couldn’t meet our gaze.

I never intended for this to happen… but as Miu told me, I moved my hand just a little.

Her chest was so soft that it changed shape in response to my touch, and her flesh embraced my fingers so gently, as if to engulf them.

(Do I actually not want to hand her over?)

Tomita has feelings for Miu… Even if Miu never looks at him, at this moment… I had this selfish thought that I don’t want to hand Miu over to this guy. 

Above all, it’s despicable that I feel a sense of superiority touching Miu’s body in front of Tomita, who knows nothing of our feelings for each other.

“Uh, excuse me…!!”

Tomita turned away and ran as if to escape.

He panicked to the point of colliding with pedestrians several times while running, and it made me worry if he was okay.

“Hey, Nii-san?”

“What is it…?”

“How long are you going to keep groping?”

“…Hah?”

I quickly released my hand.

Miu was grinning as usual, but her eyes somehow conveyed even kindness… I thought to myself that I wanted to keep gazing into those eyes forever.

In the end, we finished our shopping as usual.

“…Haah.”

After returning home and going back to my room, I kept staring at the palm of my hand… and ended up being tormented by the incessant pounding of my heart.

“…♪♪”

As Nii-san headed towards the bath and I prepared dinner, I remembered. When we met Tomita-kun during our shopping trip, I excitedly showed him the intense relationship between Nii-san and me through our cooperation… It was really thrilling.

Of course, it hasn’t progressed to the point of a real relationship, but at least Nii-san has been conscious of it ever since, speaking fewer words. I’m confident that if I keep pushing, we can go further.

“But… I’m in trouble, you know. I’ve looked up things like sexual acts and videos on the internet to gain knowledge for Nii-san’s sake, but just being touched like that… it’s enough to make me like this.”

I want to get into the bath as soon as Nii-san comes out… That’s why my underwear has become a bit of a mess.

“…My precious girl, huh?”

Those weren’t words we planned or coordinated. They were Nii-san’s sincere words… Those words made me so happy that I almost started crying, and I desperately suppressed the impulse to forget about pretending and call him Nii-san while hugging him tightly.

“Hah… Love you, Nii-san♪”

I can’t stop this anymore.

I will be the one taking the initiative… I will keep advancing and advancing… We will definitely be in a loving relationship, Nii-san and I.

Mom and Dad are cheering us on too… By the way! Nii-san doesn’t know about this… Of course♪
