I Was Reincarnated In a Yandere Main Love Comedy Game And Suddenly a Dangerous Girl Became My Younger Sister - Chapter 57

“……It’s hot isn’t it”

“It’s hot isn’t it”

With the window fully open, Chisome and I muttered while looking out at the garden.

It will soon be August, which means that summer will also become the real deal, nonetheless, it’s not so much that our sweat were to flow endlessly, so we didn’t turn on the air conditioner and open the window like this.

“Onii-sama, Chisome, it feels good.”

Ahead of such Chisome and me’s line of sight was Mashiro bathing in the vinyl pool we had just bought.

It’s a vinyl pool, so the size it’s not that much, and the range of movement is also minimal, but…… wonder what it is; just scooping water with her hands and bathing her body, that figure is really pretty.

“Somehow, it’s like a scene from a manga isn’t it, Mashiro now is.”

“Sure is”

Right now, Mashiro’s appearance is wearing a white bikini, and if the black skin that remains were to be excluded, it would become to the point where it’s completely no different from human skin.

When such Mashiro is bathed in water, the droplets reflect the light and sparkle accordingly, such is mysterious and ends up making me stare at it.

“You two, not going in?”

“Ahaha, As one would expect” (Taiga)

“It’s small after all right. For now, have fun with just Mashiro okay?” (Chisome)

“Muu……Okay”

In any case, since if we go to the pool, or even go to the sea, we can play as much as we want.

It’s enough for the three of us to play in the water to our heart’s content at that time anyway, and for now I’ll be satisfied with seeing Mashiro playing cutely see.

“Nee Nii-san”

“What?”

“Because my oppai (breasts) ended up getting bigger. Can I go buy a swimsuit again this year too?”

“-……That is well, yes.”

“Ehehe♪”

Of course riight, Chisome is also growing in comparison to last year.

Not only did she grow slightly taller, but her plump bust also grew even bigger, which is a little hard to tell from her appearance, but if you rub it or touch it, you will surprisingly notice it.

“Even I’m myself surprised, but it’s still going to get bigger isn’t it~.”

“Stiff shoulders and the like, are you okay?”

“U~n, It’s true that my shoulders are stiff, but that’s as far as it goes, I think. Since I can reduce the burden in various ways by applying power, see.”

“You can do that sort of thing too?”

“Un. When I talked about that, I got envied by Misora-senpai you know.”

“That’s……well yeah~.”

Misora is the owner of an overwhelming enormous breast that exceeds three digits; so it seems that she is always tormented by stiff shoulders; but that seems to be exactly the case.

However, when I think it over carefully, Chisome’s official setting bust is 95 cm…… That is now ninety-eight, and it seems that the growth still won’t stop.

“Nii-san is perverted, you keep fixedly staring at it”

“Oops, that’s rude of me”

“I don’t particularly mind, you know~? I mean, we are lovers anyway, and since this here is our home, even if you touch it, rub it, suck it, and even do whatever you want is fine that’s why.”

Eei (you there), you don’t have to go so far as to say it so graphically I say!

However, when she ends up telling me like this, for my eyes will end up turning that way is only natural. When the plump cleavage peeks over a cool-looking shirt, the sweat flowing in the cleavage is vividly engraved in my mind.

“Naa Chisome”

“U~n”

“Why are you that lewd?”

“It’s because I am Nii-san’s little sister?”

“……I see~”

“Un. It’s because I am Nii-san’s little sister okay? I’ve always been thinking about Nii-san, so not only my thoughts but also my body end up becoming lewd to Nii-san’s taste.”

“……………”

“Of course, even before I started dating Nii-san yet, I was thinking about Nii-san and had sex with him alone, which probably played a big part though.”

“……………”

Kuu……my little sister… my lover is too lewd it’s painful…… No, it’s not painful but, it’s something like this, the emotional uplift that cannot be expressed in words is terrific!

If this goes any further and if I don’t do anything, my thoughts will be wrapped in naughty things, so as to change my mood, I headed to the freezer and took out three ice creams.

“Chisome, Mashiro too, ice cream”

“a, thank you”

“Thank you Onii-sama”

After that, the two started eating ice cream, with me sandwiched between them…… It is however, instead of calming my mood, I had to fight even more worldly desires.

“amu…….un……reru” *eating ice cream sound*

Chisome’s way of eating ice cream is too radical.

Unlike Mashiro, who licks the ice cream cutely for her age, Chisome eats the ice cream with her tongue, as if she were licking all over something.

While lifting the hair hanging on the ear with a free hand…… wait, am I the bad one about this, or is it because my heart is getting dirty.

“……Fufuu”

No, apparently, it looks like Chisome was deliberately staging that.

She glanced at me with a sideways glance, grinned and smiled, and then proceeded to give another lick that was even more flirtatious. She did, however, perform the way of licking that incited the excitement.

“Wait, oi, when you do such way of licking――”

Covered with saliva; moreover, in this hot sunlight, the ice cream naturally melts.

In other words, a piece of ice cream about the size of a thumb end up crumbled, and that fell *plop* on Chisome’s chest.

“Kyan!”

“……………”

Even though she was aware of how she was eating it, the coldness that came suddenly seemed to surprise her.

The thick fluid from the melted ice cream was sucked into the cleavage, and the coldness seemed to flow along the skin and down to the belly button.

“……Chisome, what are you doing?”

Such Mashiro’s few words deeply pierced Chisome.

Chisome shyly got up in silence and headed for the bath as is.

“Chisome is, when Onii-sama is by her side, she soon colors with idiotness.”

“……Well but, it’s a cute thing it is.”

“I think so too on that. Chisome is cute no matter what she does anyway, adorable no matter what she does always……to the extent that I can’t imagine she’s eating someone anymore, Chisome has changed.”

Mashiro began to talk.

I put away her usual childish demeanor at the bottom of my heart, and with that, it gives her the atmosphere of an older sister like her, who treats the Chisome I saw in the game like a younger sister.

“All that, too, was because I met Onii-sama. I have always been seeing a dream……of Chisome can never be happy. Attacked by Rikudou Taiga and his father, she despairs over everything and changes into a monster that only eats people, continues to slaughter, and about the last is being sealed too.”

“……Mashiro?”

What is she……what are you talking about, Mashiro.

“What awaits at the end is an eternal prison and suffering, and Chisome continues to hold a grudge against everything until her soul loses its radiance, never dies, all the way to the point where her own existence becomes ambiguous……”

“Mashiro!”

“-……Onii-sama?”

The atmosphere until just now is gone, and Mashiro returned to the usual her.

“I……what did I say?”

“……Well, many meaningful things, I guess.”

“……somehow, I remember though.”

“I see……”

I embraced Mashiro’s body.

She’s still in a swimsuit, so I’m in direct contact with her skin, but as expected, she’s got the warmth of a human these days.

Nonetheless, rather than such that, there are things that should be told.

“Naa Mashiro, As Chisome’s big brother, I intend to protect that girl always. Of course, she’s not just my little sister anymore; she’s my girlfriend, that’s why. Exactly that, I’ll bet my life, I intend to be by her side.”

“……Un”

“Since we don’t know the source of Chisome and Mashiro’s powers, there might be some truth still hidden. But, whatever happens, it’s going to be okay, I’ll be puffed up with pride and say that alright. Because that’s me, living in the present Rikudou Taiga.”

“Onii-sama……Un”

If I think it over carefully, this or that, there are many things I don’t understand isn’t it.

But, I don’t know why, the feeling of even if I worry about it, it’s useless, too, it’s a strange feeling…… Exactly that, it might be because I’m already off from the route.

“Besides, we have more friends we can rely on anyway right.”

“That is… that’s right, isn’t it. Somehow, I feel invincible.”

If Mashiro thinks so, it should be safe.

Both Chisome and Mashiro have sharp instincts, so if they sense danger, they’ll even end up taking a stand against them, but if that’s not the case, they wouldn’t be feeling this lighthearted.

“But, the one who has changed is me too. I mean, to think that I would come to love someone, it’s an impossible thing after all. I’m glad I met you, Onii-sama.”

“……Flag?”

“No, it’s not. Well, no matter what kind of flag there is, I’ll show you I’ll pulverize it though.”

“Pulverize you say……”

“It means I had that much enthusiasm”

Well, it means nothing happens is the best, though.

Besides, this year’s summer vacation isn’t just about hanging out with friends and merely making fun memories.

For Chisome, in the truest meaning, there was a determination she held to free herself from her curse.

“Nii-san, I you see? To that person……I’m thinking of let’s go meet my mother (Kaa-san).”

Chisome’s eyes were serious when she said that, and she, too, knew that the fence with her family was something that had to be settled and done.

If so, I will just support her.

Without denying Chisome’s determination, pushing her back is something I can do.

However, to properly watch over her from her side was the only thing I firmly nodded at.
