Yandere Chisome

Morning, when I woke up, Mashiro was looking down at me.

"Mashiro?"

"Un"

Why Mashiro is......that's what I thought, but the moment I saw her face, I remembered everything about yesterday.

Chisome was also Mashiro; in a way, it was a night with a deep connection between the two.

"-......"

Just remembering it overflows with happiness is as a matter of course, but there is also around the same amount of embarrassment about it.

Chisome had already woken up and I guess was preparing breakfast, but looking at who could be said to have the same existence as her, Mashiro, after all my cheeks are becoming warm.

"Uhh......morning Mashiro."

"Un. Morning Onii-sama."

When we exchanged greetings, Mashiro fell down on me as if she had lost all her strength as it is.

Naturally, I caught her in my arms, but Mashiro still buried her face in my chest as it was, which ended up with me not being able to move.

"Is anything wrong with you?"

"......because I get embarrassed when I look at Onii-sama's face."

"Isn't that......"

"Because of yesterday, I remember everything."

I don't know in detail what state these girls were in at that time, but I wonder if Chisome was their main consciousness, and Mashiro could also be able to see while inside in the end......I'm a little curious, but enough with this; let's just go to Chisome.

When I opened the door to the living room, the smell of delicious breakfast wafted in the air, and just right Chisome was tasting the miso soup.

"Un, it's perfect isn't it...... Ah, Nii-san morning."

"......ossu"

Chisome looks the same as usual, or so I thought, but she slightly blushes her cheeks and smiles embarrassedly.

Although we are brother and sister with no blood connections, this sort of part might be similar after all.

"It'll be ready soon so sit down. Mashiro, will you help me carry it?"

"Okay."

Mashiro, who had been stuck to my back the whole time, also joined in to help, and soon all three of us were together for breakfast.

However, what was different from usual, was that today's dining table was quite quiet.

Me, as well as Chisome and Mashiro, are eating quietly without letting out a word...... Well, it's not a bad thing to be quiet while eating, but the three of us definitely ended up being quite conscious of the thing yesterday.

"......Un?"

"......"

In the midst of all this, I suddenly felt a strong gaze on me and I looked at Chisome.

She was staring at me with those red eyes, but even though our eyes met, she wasn't particularly upset and continued to stare at me as is.

(This is......a test of patience?)

That may also be it, but the number one thing was that Chisome's desire to talk without being embarrassed was conveyed.

Basically, although Chisome stands out for her relaxed state, at times like this, sure enough, she seems to be getting unbearably embarrassed as well...... If so, then I can't keep being led by my little sister forever.

"Chisome, and Mashiro as well. Yesterday was a really happy moment...... that's why, um, from now on too once again let's get along okay."

"ah......Un!" (Chisome)

"I got it......-!" (Mashiro)

To tell the truth, I was bracing myself this morning for Chisome to tell me her impressions of yesterday's events, even if not being persistently so...... What, it was just the figure of my little sister, who was being cute and shy, that I saw.

After that, we gained back our usual condition and it became a lively morning as usual.

"......Fumu" (Taiga)

"Is anything wrong?" (Chisome)

I didn't intend to be conscious of it, but my gaze was naturally drawn to Chisome.

She's usually very cute, and that she's beautiful is an absolute recognition that exists in me......that hasn't changed, but just what is this feeling that ends up making her look more attractive than usual today?

"a, could it be that Nii-san is getting more captivated by me than usual?"

"You get it well didn't you. Un, that's exactly right."

"Clearly nodding to it, I see~."

Of course, not just Chisome, but I also felt the same way about Mashiro.

Mashiro was staring interestingly at us while eating yogurt, but I asked if Chisome knew anything about this phenomenon, and she says this.

"Look, they often say girls become pretty when and after they have sex or something, right? For me to be honest, all I could think of was about that my skin was much more taut than usual this morning but, it could be that might be what it is?"

"......I see. Certainly, I've heard of that too."

Like, how about the increase in secretion of pheromones by overlapping bodies with the opposite sex......I don't really get it, so I might be wrong about it, but perhaps that might be how it is of what I feel about her.

"There, there, if you take it slow too much, you'll end up be late, you know?"

"Oops......ah, that's right, Chisome"

"What?"

"We're going together right?"

"Of course♪"

Yesterday, things came to be for us to go home together, but from today, in this way it also became possible to go to school together.

It happened when she was in middle school as well, so there hasn't been that much of a change, but since then we've both grown up even a little and became lovers, and that meaning has changed in a big way between now and then.

"I'll go out first."

"Un. Wait for me a little okay."

After finishing breakfast, Chisome said she still had some preparations to do, so I went outside first.

Mashiro, who doesn't need any preparations or anything else, is standing next to me while holding my hand, and in the case of Mashiro, I've noticed about her touching my body like this has increased recently.

"Somehow, it’s only natural for Mashiro to be by my side, or rather...... Even when I'm thinking about Chisome, I view and treat Mashiro in the same light riight~."

"It's not wrong. Because Chisome and I are like that. Even if Onii-sama thinks only of Chisome in his heart, there I'm also in it. That's why it's normal."

"Fu~n?"

When I often think about Chisome in my heart, Mashiro is naturally left out many times, but there's also the effect of Chisome and Mashiro are the same being, so it seems that thinking about Chisome is the same as thinking about Mashiro.

Maybe that's why when I think about Chisome, my feelings were also conveyed to Mashiro, it means.

"......so it's just a matter of perception on that point as well in the end right. It's a strange thing as usual."

"That's who we are; that's why. But......I'm happy from the bottom of my heart that Onii-sama recognized me in this way, I think."

"That is......"

"I've always been praying for that child......for Chisome to be happy. Precisely why, if Onii-sama could make Chisome happy, the pros and cons didn't matter. However, if I ended up knowing this kind of warmth and happiness, and if I also think I wanted for you to recognize me too, by some chance I might have done something strange that's why."

At that point of thought, I said, "Any other person anywhere is no different, I think," and I stroked Mashiro's head.

“I’m sorry for waiting~......wait, just you both are flirting~!”

"Un. Just now, Onii-sama was flirting with me."

"......Well, it's not wrong though, but"

It's the word flirting, that word see.

With Chisome joining us, Mashiro slipped into her shadow, and we held hands as we walked down the road up to school.

“Naa Chisome, how was your class group?”

"......U~n, setting aside the boys, as far as girls are concerned, I can get along, I think. I have some acquaintances from middle school as well, that's why."

"I see. If that's the case then I'm glad."

Setting aside the boys......I see.

For me, it's not interesting to see Chisome's figure get along with other boys, but just because, I intend not to be narrow-minded enough like restricting class socializing.

(In the first place, I can't imagine the moment this girl leaves me riight...... This is neither self-conceit nor arrogance, for some reason I think so)

My heart is connected to her...... Precisely because I know that clearly, thus came this feeling.

"People comes increasing, eh."

"Sure seems like so~."

Being close to the school means there are many other students as well.

We didn't let go of holding hands even in the midst of all that, so naturally we both in its own way ends up gathering a lot of attention.

"What kind of things people around are thinking I wonder?" (Chisome)

"Who's standing next to that beauty, isn't it" (Taiga)

"'It's my lover~♪' to say out loud no good?" (Chisome)

"As expected, standing out that much is a let's not do alright." (Taiga)

"I know. But......Fufuu, from now on, my high school life with Nii-san......my heart's beating really fast and excited a lot you know♪" (Chisome)

"So do I." (Taiga)

It was at the time we were having such an exchange.

"Rikudou-san, and Chisome-san as well, good morning!"

"-!?"

"What!?"

Whose standing behind and breathing heavily was Misora.

Chisome and I were too surprised that we ended up hugging each other, but even that too seemed to be a reward for Misora.

"......Um, Shindou-san......you're a senior (senpai), right?"

"Is there anything!"

"......even I and that girl couldn't detect you until you came close. What are you?"

"I'm a lady who just watches over you two♪"

It wasn't long before Chisome whispered into my ear me saying, "Nii-san, this person is scary."

Or rather, to think that Chisome and Mashiro didn't notice her......no way, this girl called Misora, are you saying she is evolving.

"Fuhe......Fuhehe♪"

For the time being, hasn't this girl become more dangerous than the original work?
