Yandere Chisome

"That looks like really lots of fun. Good things are good things."

In front of my line of sight, while Shinji and Kouki were making a fuss, Mashiro and Yuika were buoyantly floating with swim rings.

All four of them had happy smiles on their faces, and I was relieved that Mashiro also seemed to be enjoying herself well.

"Nii-san, how was it?"

Actually, until just a few minutes ago, we were hiding behind a rock and making love for a bit.

It was not my original intention to do so, but it wasn't strange either if I were to go to the quiet shade of a rock with my beloved lover and for things to become like that, so if I were to be asked which one, that would be Chisome, who was the one who invited me, but anyway, we made love.

"Munya......Nii-san......Suu"

Such her was taking a break under the parasol together with me, but when I realized it, she was asleep with my knees as a pillow.

Although she's still a child in her first year of high school, her appearance and body are definitely approaching that of a mature woman...... If I end up saying so, I can say that the style and the like are overwhelmingly superior to normal.

The figure of such a child, now asleep with drool hanging down, was truly adorable.

“......So Misora?”

"Ye-, Yes!?"

Misora, who is taking a break with us, has been on a trip the whole time ever since we returned, or rather, she seems to be in a trance, and her reply became like this.

"Are you okay?"

"I'm okay. Indeed, I'm okay. I am fine as ever fine."

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

Un, she's not okay at all.

Chisome tapped Misora *pom-pom* on the shoulder when we came back, so she seems to know what happened, but, well, if said person doesn't speak, then there's also no need to ask, I guess.

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

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

But things are quiet, huh.

When I look next to me, Misora staring motionlessly at the four of them happily playing, and when I lower my gaze a little, an extra-large bust that I had been taken care of how many times in my previous life...... Fuu, NGNG, I shake my head and obliterate my worldly desires.

"......Naa Misora"

"-......What is it?"

"Thank you. Not only Chisome, but for becoming friends with Mashiro as well."

I didn't particularly have anything to say, but these kind of words naturally leaked out.

Misora looked open-mouthed and rounded her eyes, but she immediately giggled and clenched her fists, saying that such a thing was only natural.

"Rather, I would like to express my gratitude to Taiga-san for giving me this kind of opportunity. For awakening me to the wonderful thing called brother-sister love and for teaching me the true beauty in this world, thank you so much."

"Was it that far really"

After all, Misora is just a little too awakened.

Misora firmly made a strong fist and smilingly seemed to be having fun, and although Misora gave off a vaguely invincible image, she immediately changed from that cheerful look to a serious expression.

"Taiga-san"

"Un?"

When she looked at me like that, I also naturally straightened my posture.

"I am really glad to have met you all. To tell the truth, sometimes I think I've gone a little too far, but even so, I intend not to cross any lines that should definitely never be crossed."

"I......suppose so"

Well, setting aside whether there is such a line at the moment, this or that, Chisome and Mashiro seem to be having fun anyway, and although I do have things that get me tired, I don't feel bad about it.

She took her gaze off from me and turned her gaze to Chisome, who continued to sleep comfortably.

"She's really cute, isn't she"

"Yeah"

"I have wondered how many times that if this kind of girl were my little sister, I would want to grant anything she wished. And then there's also a vice versa to that, I wondered how happy I would be if Taiga-san were my big brother."

"......Is that so?"

"Yes. I have my inclination (fetish) ended up twisted hard――please take responsibility."

"Why is that"

"Ufufuu, I'm just kidding♪"

After Misora put her hand on her mouth, I didn't expect she would say something like this.

“I heard from Chisome-san, is it true that if Taiga-san hadn’t met Chisome-san, there might have been a future where you would have fallen in love with me?”

"Buh!?"

I almost ended up spitting out the juice I had in my mouth.

I wondered what she was saying all of a sudden, but it is true that I talked about it to Chisome anyway, and I had also told Yuika something similar.

To say that I took a liking to Misora might mean the same thing as I like her, but I didn't think Chisome was talking to her about that.......This is so embarrassing; what am I supposed to say back?

"Imagining that makes me happy. To be with that Taiga-san......That's why."

"......Well, it's true that I would have thought about it if I hadn't met Chisome I guess. I can't imagine it anymore though."

"I know. Because I don't think so either."

What if Chisome and I spent the whole time together as brother and sister...... No, if that were the case, I wouldn't have gotten along so well with Misora.

That kind of world might have also existed by some chance, but imagining it has no meaning.

"But it's also a woman's nature to be curious! I wonder what part of me is the main cause that made Taiga-san think like that!"

Well yeah it's your, after all, the number one are those oppai. *breasts*

There should probably be two types of players playing Byouai who fall in love with Misora.

First of all, when they see Misora's character design, they will probably be separated into those who are attracted to her big breasts and those who are attracted to her beautiful appearance, but from there, it is probably the flow that they will learn about the character of Misora and fall in love with her, which destroys some people's disposition to have a classmate become their big sister.

"......-! Sheesh oh you, Taiga-san!"

"Sorry"

When I looked fixedly at her breasts, Misora hid them with her hands in embarrassment.

However, even so, it wasn't hidden, and on the contrary, the shape was distorted due to the position of the arms, making it an even more indecent sight, but Misora didn't seem to notice.

"Well but, a lot has changed since I learned about Misora as a person. I don't know what to think about you getting aroused about me, Chisome, and Mashiro, but at least it's not without consideration. That's why I don't think I hate being by your side, see."

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

"So, well, I guess I can dare to say this. Me now, I really trust you as a friend, and in that way, I like you a lot."

"-......"

Yes, that's precisely why this feeling never develops.

No matter how much I like Misora, no matter how much I think she's a good woman, in the end my feelings won't sublimate beyond that.

"Me too...... I like Taiga-san too. I like Chisome-san and Mashiro-san. I want to be with you all as a friend for all time, even when I become an adult always."

"Well, won't it continue? It's about Misora anyway, so just leaving after graduation won't be a breakup, right?"

"Of course! Rather, I'm in the mood to give my care♪"

She said so by clapping her hands with *pan*.

It's true that continuing to be loved by such a girl would also be a blessing, but the dread of its nature is that there is no such emotion as weariness or the like involved.

Because she makes you so dependent on her that she'll make you feel like you want to drown more, be loved more, and even go as far as to remake your personality.

"Well, that's so Misora-senpai like, isn't it."

It was Chisome's voice that resounded there.

Before I knew it, she opened her eyes and gave me a smile, then sat up and gave me a light kiss on the cheek.

"Ara, ara, my, my!" (Misora)

"Don't get excited" (Chisome)

Chisome lightly tapped Misora on the shoulder.

After that, Misora said that she was going to cool down her body and headed over to everyone, and I sat side by side with Chisome staring at them.

"It's really fun. It made me think that this world is not yet something to throw away."

"That's a line like the last boss."

"In a way, I am the last boss, aren't I"

"You're not wrong"

In the distance, Mashiro and Yuika together wave to us, so I wave back along with Chisome.

Seeing not only Chisome but also Mashiro smile, I have thought many times, but from the bottom of my heart, I was really glad that we came here like this, and that I was glad that the two of us were able to make many friends.

"Nii-san"

"Un?"

"I am happy. I'm glad I was born into this world."

...............。

More than anything else, those words make me happy alright, Chisome.

"Nii-san, are you crying?"

"......shut it"

Seriously, why is this body so fragile to tears?

If this is the case, if at some point in the future I end up having a child with Chisome, I'm worried that I'll be so moved that I'll flood the place.

“Come now, Nii-san, let us go play too!”

"Ou!"

Chisome led me by the hand, and I headed to everyone.

Thus the best part of the summer vacation passes, and then the time comes.

The time has finally come to show Chisome's determination.
