Yandere Chisome

It was the night of the entrance ceremony that marked Chisome's start to high school.

After finishing dinner, while lying on the bed, I was thinking about what had happened since I met Chisome.

"......Really, I've ended up coming this far aren't I~."

The time when the story I know about Byouai begins, and of course, I am also truly deeply moved by being welcomed as Chisome's older brother.

I've almost ended up forgetting it now, but when I met her, I was really taking it shocked, and as Chisome knew, I was really being fearful about when I would be eaten and killed.

"Onii-chan?"

"O-, Ou"

Chisome is cute, and she, who was called Kuro Chisome until a little while ago, Mashiro is also cute...... However, sure enough when I touched her for some time after I met her, an unknown fear I had is definitely there.

"That's now and became......a lover huh~."

Nowadays, I've been thinking for a little bit, that it's natural for me to think of Chisome as my lover, and I also think the same of Mashiro.

To be honest, I can't explain this feeling well, but......it's true that they each have their own will, but they are also the same existence...... In other words, even supposing that there are two people there, sometimes I feel it becomes like I'm in contact with one person.

"The feeling that even when you are talking to one of them girls, the other is always by your side...... I really can’t put it into words this is."

I was thinking about something difficult for a while, but......maybe that's why, I became very sleepy and just closed my eyes as it is.

Then, an extremely strange sight unfolded before my eyes.

More or less, I still have memories of being in my room until some time ago, so in case such a mysterious phenomenon like this occurs, I can basically recognize it as a dream.

"......wait, oi, no way is this here is!?"

The scenery in front of me, that is my high school classroom.

What's more, there's no doubt that what's in front of me is――Chisome.

"You did well to come didn't you~. With me......?" (Chisome)

She looked exactly like the figure of a girl who was always by my side; however, that atmosphere she wore was completely different.

Despairing over the world itself, to see her figure, who became unable to trust people, I instinctively reached out my hand.

"Why......why......-!?" (Chisome)

Seeing Chisome's distraught state as though she had seen a ghost, I instantly guessed the present condition.

This is a dream, but by some chance it might actually let me meet the real Chisome...... Well, nevertheless the Chisome in front of me and the Chisome by my side are different......but, as expected, there was something that touched my heart when I was shown such a state like this.

"Chisome."

"Don't come!!"

When I took a step forward, something like a black whip appeared from her side.

That was struck in front of me, and that alone caused the desk to crack and split in two like a fissure in the ground.

"Why? I certainly ate you......and yet why!?"

If supposing there was an existence who led this encounter, just what kind of purpose to prepare this chance meeting was, I don't know.

However, once again, a fire of determination was lit inside me.

I am absolutely, resolved not to let the girls by my side make such a face like this.

"Be gone! Don't come out in front of me ever agaaaaain-!!"

The black whip took on a sharp look and drew near, pressing down on me.

If this pain is going to wake me up from the dream......No, I still don't like it, I thought, when I hear another voice.

"Nii-san"

"Onii-sama"

The moment I heard that voice, all the attacks that were approaching me were repelled, as if my consciousness were being pulled and awakened by the voice I heard.

"......-"

"a, so you're awake Nii-san"

"Onii-sama, did you have a scary dream?"

When I opened my eyes, what's beyond me, who's peering into my face were my little sisters.

Scary dream...... Well, it sure was a scary dream, and I smiled wryly as I looked at the clock to see how long I had slept since then.

"I have slept for about thirty minutes, huh."

"Seems like it. You slept soundly, but......it was a little like having a nightmare. Could it be that Nii-san?"

"Aah no, it's not the kind of dream that Chisome had in mind. How should I put it, in a way it's like it was a necessary dream I think also."

I said that, come near and embrace Chisome and Mashiro.

"Chisome, Mashiro too...... From here and now on, no matter what happens, I'll show you I'll protect you as a big brother. Of course, as a lover as well okay."

"Nii-san......fufuu♪"

"Onii-sama♪"

After that, I killed time together with the two, and when the time became near ten o'clock, I headed to bed.

"............."

To tell the truth, there is something I have always remembered.

That is, when Chisome became a high school student, let's have lewd acts, and despite also being so embarrassed like that, the promise made to seek a deep connection with each other.

"Nii-san, I, you know? That time promise I remember it see."

".......Me too."

"Ahaha, oh Nii-san, your face is red I tell you!"

"And Chisome too, right!"

I could understand as if taking it into my own hands, that each other's faces were red, and our hearts were pounding.

The one staring intently at our exchange was Mashiro, but when I thought that Chisome beckoned Mashiro, something strange happened.

"e?"

Mashiro overlapped as if being sucked into Chisome's body.

That was a spectacle that could never happen in reality, and it was too mysterious a spectacle that I'm at a loss for words.

"We are one and the same existence, precisely why I'm glad to have the first time with Nii-san to be at the same time."

"......I see?"

Chisome now has a rather special appearance, and while it feels like black hair is mixed with silver hair, the red line seen on Mashiro's body is also visible on Chisome.

As if, I got the impression that, like Chisome and Mashiro had become one.

"Nii-san"

"......Ou"

This's bad, coming this far; the tension has been coming assailing me tremendously.

It's true that what we're doing from now on, if one were to call it an embarrassing act, is an embarrassing act, but it's not as if it's something that's abhorrent, and if it's as lovers, it wouldn't be a particularly strange act to do.

(Naa Taiga, your beloved sister, say it like this for you, you know? Don't go thinking about an embarrassment, among other things, then comes hesitation and ruin it all!)

Thinking that, *pashii* I slapped my cheek.

As I heard from Chisome, so far, there have been times, many times over which we have been turned on, but each time we've held back and endured until she reached the milestone called a high school student.

"......Chisome"

"-......Yes"

I face Chisome, and until now I've done it many times over, but once again, to boost my spirits, I kiss her.

When the kiss changed from a mere touch to the lips to a violent one with tongues entwined, there was a sense of comfort that gradually made my head feel like it was floating.

The thought of Chisome in front of my eyes is more precious than anything else, and it's as if my brain orders me to, at any rate, love her entirely.

"Shall we go to bed"

"Un"

I laid Chisome on the bed, and furthermore took a position as if to cover, and overlap her.

"......I, have been waiting for this for a long time. In this way to be able to connect deeply with Nii-san, it's finally coming true today isn't it."

"That goes for me as well. Chisome, I love you."

"I love you too"

"......"

"......"

"......uh"

"First of all, Nii-san, touching my breasts or something is also fine, you know?"

"......ou"

It's kind of a mutual groping.

After that, we spent the time laughing and panting with the vigour of attempting various things; and it was already about to become twelve o'clock.

"......Nii-san, I love you."

While holding my arm, as if pressing me against her voluptuous body, Chisome is there by my side.

As a matter of course, both of us are not wearing clothes, and Chisome is still in the state of being fused with Mashiro, so is that girl is sleeping I wonder?

"Mashiro also seems a little tired. Rather than that, I do also think the sex with Nii-san felt good, but perhaps, it might be that I still haven’t caught up with the happiness that came to my body."

"Was that so...... Well, I'm glad everything's okay."

"Un♪"

However......if I can say one thing, I definitely had sex with Chisome this time.

Without a doubt, the only one I touched with my hand was Chisome, but in some way, I felt as if I was being touched and also enveloped by the two at the same time, so I guess that's what it means for the saying "the two are connected".

"But......it feels like a new option, isn't it. During the time we spent together as lovers, we've without a doubt found new ways to love each other." (Chisome)

"I think so too. Let's, do it again okay." (Taiga)

"Of course you know. Rather me, I did say let's do a lot, didn't I?" (Chisome)

"......Un" (Taiga)

"Fufuu♪" (Chisome)

It's a strange feeling.

As if Chisome ends up looking much more adult-like, more than before her body and Mashiro's overlapped.

"Nii-san, I love you, lo~ve, I love you lots~♪"

"......Chisome is too cute!!"

"Right~? Me, If I think of Nii-san, I'll become infinitely cute after all♪"

"......I'm really glad I'm alive seriously."

"Nii-san, are you going to cry?"

"I'll cry."

Spending time with someone you love is this much warm and happy feeling isn't it......that was evidently the night I felt a woman's body.

In this way, I spent the first night I promised with her, and our relationship is tied even more intimately.
