"Dear customer~? Are there any itchy spots~?"

"Is there any~"

“Thanks to you two. I feel good, very.”

Me, I'm in heaven now.

When it's time to take a bath to wash away the fatigue and sweat of the day, if it's the usual, I would take a bath peacefully by myself, but today believe it or not, I'm bathing with my two little sisters.

As you can already tell from their lines just now, the two are washing my body with lather on a towel....... This is happiness, I thought, what else can I say other than it's heaven, huh.

"Onii-sama is looking very happy."

"Fufuu, it means that’s a good thing that is. Now now, I'm pouring~"

Hot water was poured over my shoulders, and the bubbles clinging to my body were washed away.

Neither of us had a towel wrapped around our bodies, so the various places, such as important parts, are completely visible, but this much are not something to be shy about anymore.

That being said, both Chisome and Mashiro have attractive bodies, so it's natural to be turned on, but I can endure it.

"......Oh, it's about to start."

"Ah~, TV, huh"

Just when Mashiro finished washing my body, she left the bath at full speed.

The time is around 6 o'clock in the evening now, but there are TV shows that Mashiro is into at this time of the day, so apparently that is something she really can't miss.

"This is coming from me, I know, but she had become more human, or, how should I put it" (Chisome)

"Isn't that a good thing" (Taiga)

"Well yeah♪" (Chisome)

At, Mashiro is also no different from humans anymore, we laughed.

"Well then, Nii-san."

"Ooh, leave it to me."

Chisome sat down in front of me with her back turned, so now it's my turn to wash her body.

I don't have any intention of saying that my body myself is filthy or something. But Chisome's body is really beautiful without a single blemish, and honestly, I'm being fearful of what I should do if I were to put effort into it poorly and get a mark on it.

(Well, I'm also able to get used to it little by little though.)

When I'm washing Chisome's body as I gently stroke it, she's giving me a comfortable look with it as well, so the amount of force seems, in general, not wrong.

After washing her back and running the hot water, she turned her stomach towards me.

Her large, growing breasts were shaking like jelly on the beat. Giggled, Chisome smiled and mouthed a please for the front, too.

"......You're right. To run away from this it can't go, I was washed too anyway."

"UnUn♪ That's right, isn't it~? It's not at all like I actively try to eliminate the escape route, you know?"

"That, isn't that the same thing as confessing yourself?"

"You could also say that~♪"

I let out a sigh at my little sister's proactive behaviour, and came to wash her with my hands firmly.

Wash not only the shoulders and stomach, but also while feeling the softness of the chest properly, and moreover, wash the parts that are hidden by lifting it up as well......and when everything was over, Chisome and I were soaking side by side in the bathtub.

“Fuu, after all, taking a bath with Nii-san is exceptional.”

"Is that so? Well, I'm happy about it too, but it might be a little tiring."

“Because of being nervous or something?”

"Aah"

Although I'm used to it, I get nervous all the same, so please understand it.

"Tsuntsun" *poke*poke*

“...............”

"Ehehe♪"

Just when I thought "it had quieted down, huh," Chisome is coming to poke my shoulders and cheeks and goes out of her way to say tsuntsun, so I also try to poke her cheeks as if to counterattack.

The feeling of the soft and bouncy skin was very pleasant, and as an action for wanting to mess around lightly, I was convinced that certainly it was making me want to do it.

"And then Nii-san?"

"U~n?"

"Did something happen at school? Haven't you been thinking the whole time about something?"

"......Ah~"

At Chisome's words, as expected, she was watching me well, I thought, and smiled wryly.

"Well, it's not something to hide, I guess. Actually――"

I explained to Chisome what I saw on the school rooftop.

Doing so, although Chisome's expression distorted in displeasure at the first name that came up, and moreover, hearing the words that followed, her appearance became one that shows an immense curiosity.

"No way, that wrong idea guy is like that, I see......Fu~n"

I thought he would get despised by her without doubt, but Renjou Shigure seemed to take a liking to Souma.

However, that way of liking him wasn't normal, and her words and deeds were exactly what was called a yandere, even as far as her atmosphere is concerned...... Well, as far as that atmosphere is concerned, it's because that of Shigure was resembling closely to her in the game.

(Seeing that Shigure, consequently I'd be, now that I mention it, this world was a thing about yandere, right~ to the extent I unintentionally remembered it.)

It just, no more than a little change did happen as well is certain.

Vaguely...... The thing that really felt vague, was that it was more about Shigure's reaction than the original work, or rather, that atmosphere, I felt from it a kind of fear.

My memory of what kind of story it was about is already vague.......The only thing I can remember is about her being endowed with a special maternity that doesn't suit that small body.

"Even so, Renjou-san is it~. I did, within limitations, have conversations with her as a classmate, but she feels like a normal girl, right~."

"That's right isn't it~ That's what normal is right~"

"Un. That's why I don't have the image of her, to the point of morbidity, muttering chatters thinking about someone like what Nii-san just said though......"

I suppose so; even I never thought it would turn out like that as well.

When I first met her at the sweets shop, she was just a normal girl anyway, and she was normal even when she listened to Souma's one-sided story...... As expected, Souma seeing through the wishes she embraced in her heart, was the cause of everything huh.

"......Naa Chisome"

"Whaat?"

"For argument's sake though......"

And then I tried asking her.

"It might be a bit difficult to imagine, but for example, go and assume Chisome has, to the point of morbidity, some kind of wish in her heart."

"Un"

"That wish is known by the other person by chance and is accepted, or from the moment you meet that wish is known and is accepted, which one is better?"

"That is......"

U~n, Chisome put her hand to her chin and thought, and maybe she had come up with an answer; she opened her mouth.

"Probably but......the latter? If we go by normal, you might question why he knows, but if we go by different from normal, you would feel that matter is fate, wouldn't you?"

"......I see. After all, it will come to that, huh."

“Renjou-san also said fate and such, right?”

"Aah"

"Then I guess that's how it is right~."

In other words, it means he, who originally knew Shigure's wish from the outside, Souma, is about to come end up thoroughly granting it huh......and moreover, the feelings that are far stronger than the original work are now, about to become directed towards Souma.

"......Well, no curse on the untouchable god, huh?" (Let sleeping dogs lie)

"I suppose so. If with this that wrong idea guy did against her will or something, if Renjou-san will become saddened by something and the like, I might have intervened a little though......Kufufu♪ There's something about the atmosphere that seems like it's going to be fun, isn't it Nii-san!"

“......You're having fun aren't you, Chisome-san.”

"Un♪"

Well, if I were to speak truthfully, I'm having a little fun too.

What kind of chemical reaction will occur, and how will the entanglement between Souma and Shigure develop from now on...... Even if I feel some fear about Shigure's state, after all, I'm curious.

"But I see now~. So that Renjou-san's state is what you call a yandere."

"What sort of thing a yandere is, or what kind of concept it is, I think people who clearly understand it are few though."

It's not like it means I fully understand it either alright......。

As I was thinking about things like that, Chisome firmly grabbed me by the shoulder.

"Chiso......me"

The atmosphere of Chisome staring at me was bizarre; her expression made her feel far more frightening than usual.

"Nii-san, if you don't stay with me together always, that's no good, you know? I won't give you to anyone, and I won't allow anyone to take you away either. We'll be together forever and ever――Nii-san and I are connected by the thread of fate. We are in a domain that no one can invade that's why!!"

With her eyes spread wide and flared up, she said so with tremendous vigour.

"......Is that what it feels like? What do you think?"

However, Chisome laughed jokingly right away at the terrifying atmosphere.

Chisome in the game was not a yandere, so it was also scary, but it even had a fresh expression is certain.

"Being loved by Chisome to the point of morbidity is also a happy thing, isn't it? I thought so, you know."

"......Ehehe♪"

At least, I don't think it's anything but happy to be loved so much by such a girl though.

Nonetheless, this exchange made Chisome hold some interest towards playing yandere.

And, not only Chisome, but I also shared to Yuika about Shigure.

"What's that doesn't that sound interesting? Hey! I'm getting curious about what will happen though!"

Yuika is also eager-ish, and it seems she will be keeping a close eye on future trends.

If I were to say it even more, maybe because he got carried away with his exchanges with Shigure, Souma himself also comes to hassle me once again.

"Ou Taiga, one heroine has come to me close at hand ya know? Just as I thought, it was fated to be this way see. So, with that being said, next time I'll talk to Yuika. Don't go about getting in my way ya hear."

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

Naa Souma, to have confidence is a good thing.

Well but, because I know the other side of things, rather than feeling annoyed or bothered and so on by these words, I feel a little like I'm just looking at a small child who is thinking, "If I can do it, I'll do my best."
