Yandere Chisome

As the summer season ends and winter arrives, Chisome's birthday also approaches.

"......Hahaa, Chisome's birthday is coming up, which means so is that girl's."

Last year too when I went home I bought a cake not only for Chisome but also for that girl, but this year even more than last year to celebrate or rather, it looks like it's going to become a fun time.

"Oi oi oi this guy's did that smiling again"

"Kuu!! Riajuu go and explode!"

"Shut up!"

It wasn't just words, but also with a moderately strong force, the nerves that Kouki tapped me on the shoulder, and I ended up letting out a loud voice.

It's not that I intend to get angry, and I get it well that Shinji and also Kouki are just grinning and amused by the current situation.

"Ever since you and Chisome-chan started dating, we've been to your house many times anyway, and we've gone to karaoke and stuff together, but each time the lovey-dovey level increases riight."

"Also in some way......you look happier than before too, or rather, Taiga’s expression changes all the time riight."

"Ah～, I got wonders about that too. Chisome-chan just smiled like she knew everything tho."

I see, (they have) surprisingly good powers of observation huh.......no, we've been together for quite some time anyway, so it's too late now that is.

It's not like anything has happened to me, but at least things have clearly changed compared to summer...... well, it seems unlikely the two will know that truth though.

"It's simple ain't it. If you had such a cute and beautiful girlfriend, you'll also be smiling grinnin' anyway and even your expression will change all the time."

"......Naa Kouki, the audacity this guy for a man got this look on his face like things are 'so easy-peasy'."

"......Us who didn't even have a gf are after all losers (of society), it means."

No, I didn't say it that far though.......

After that, we parted ways and I stopped by a popular sweets store and bought three cream puffs.

As I walked out of the store, carefully carrying the paper bag so as not to in any way drop it, I ended up bumping into someone who came out exactly from the side.

"Otto"

"Kyaa!?"

That voice now was definitely that of a girl.

It's not as if I'm aiming for it, should be, but it seems that I have a terribly connection with bumping into a woman.

"You're okay?"

"Ah, yes......I'm okay."

"......?"

The girl I bumped into is a very small girl.

Pink hair and a cute-like face girl......wait, no way I thought, and I stared at the girl.

"Ummm.......Is something the matter?"

"......No, it's nothing. Is there really isn't anywhere that hurts or anything?"

"Ah, yes! It's okay! I was also looking the other way, so I'm glad we didn't both get seriously injured!"

"How true that really was isn't it," I smiled wryly.

I immediately parted with that girl, but now once again, to the other side she rans, at the disappearing of her back-figure; I turn my gaze.

"......Renjou Shigure, ain't that the junior (kouhai) yandere heroine."

She's the junior heroine who's scheduled to enter my high school next year.

I never thought we'd meet in such a way, but from the looks of it, it seems like I won't leave an impression on her at all.

"As I recall it, the Yandere level is the top fiendish isn't it......"

Being fiendish doesn't mean being harmful; simply Shigure's essence as a yandere comes out head and shoulders above the rest, and it takes quite a while to get along, but the moment you crosses a certain line, she tries to wrap the protagonist with overwhelming broad-mindedness that doesn't match her small stature.

"Though it's a character that didn't resonate with me at all who likes big breasts."

Incidentally, she was also officially set up to be concerned about various small things.

There was an unexpected encounter with a junior heroine, but I quickly, as if to forget about it, went back home.

"I'm home~"

When I opened the front door and went inside, Chisome's shoes were already there.

This time, because from my side I promised to play with those two (his friends), it seems that Chisome went home alone, but this is if I don't make this up to her sometime soon it can't go huh.

As I was thinking about such thing while taking off my shoes, the door leading to the living room opened.

"Onii-sama!"

With a cheerful voice a girl with black hair jumps at me.

It was quite a momentum, but after all, her body doesn't weigh much, so I don't even get a big impact.

"I'm home Mashiro"

"Welcome home"

The one who hugged me was Mashiro――she was the one lurking inside Chisome.

Ever since she started speaking, and me and Chisome gave her the name Mashiro, Mashiro has grown at a terrifying rate.

Her appearance didn't change much, but her spirit did grow rapidly.

"Chisome in the living room?"

"Un. she just got back from shopping, so she's putting ingredients in the refrigerator now."

"Was that so"

Compared to Chisome, she speaks plainly, but it's not as choppy as before.

Her skin, which was overall dark, has taken on the color of a normal person, but the red lines that run down her body continue to remain, so should I say that as far as that part is concerned, it is a proof that she is a nonhuman.

When I returned to the living room with Mashiro, there was Chisome holding onions and potatoes.

"Welcome home Nii-san"

"I'm home Chisome"

When I got home, I was happy to be greeted by my two younger sisters, but sure enough, in this way I could feel a kind of warmth from the sight of my lover standing in the kitchen.

"I bought some cream puffs. Shall we all eat them"

"e, really?"

"Sweet and soft pastries, love them very."

Chisome and Mashiro both love sweet things, but when it comes to Mashiro in particular, it feels just a little like she comes to regress to an infant when faced with sweet things as well, but that figure is again so cute it makes me and Chisome smile.

"Amu......yummy♪" (Mashiro)

"I'm glad" (Taiga)

"Aren't you glad" (Chisome)

I was staring at Mashiro , who was deliciously stuffing her mouth with cream puffs *paku*paku*, but Chisome and I faced each other and closed the distance between us.

"Once again, welcome home Nii-san."

"I'm home Chisome."

I embrace her, my beloved lover, and this is the promise I made when I came back from outside.

Then, just like Mashiro, we also ate our cream puffs, but Chisome let out a small sigh and said something like this.

“I want to go to the same high school as Nii-san as soon as possible......every day is troublesome that's why.”

"......Ah～"

I smiled wryly when Chisome said it was troublesome.

I learned from her herself about it, but the fact that December is coming soon means that Chisome, who is in the third year of junior high school, will graduate in a few months, and the same also goes for Chisome's classmates.

Maybe that's why, "I want to capture Chisome's feelings somehow before I can't see Chisome anymore," or so the boys in the class are thinking, so the number of confessions seems to be increasing.

"I you see, I've talked to my friends, but not to the point it's repetitious, that I'm enjoying a sweet romantic life with Nii-san you know? Even so, so persistently they kept coming to confess......Ugaaaaaaaaaaaaa!!"

"Ca-Calm down Chisome!"

"'Cause it's annoying I want to eat it, if I do that then it will become quiet and yet!!"

My beautiful lover with her hair disheveled is being wild.

Mashiro is also connected to Chisome, so she seems to understand her worries and anger, and even while nodding her head *un*un*, it didn't make her stop her hand from eating cream puffs.

"......It would be fine if I was by your side together, but as expected, it can't go like that either being so."

"I know. But it's okay, since I'm being enveloped by Nii-san's love♪"

Saying that, Chisome bit into the cream puff.

This sight of Chisome and Mashiro sitting next to each other and eating cream puffs together, the sight of them looking like nothing but real sisters made my cheeks go soft.

Even now, with Chisome as my lover, I'm always in a state of high spirits, and there, as Mashiro has, as if joined with an even deeper connection, every day is a parade of happiness.

"I'll go put hot water in the bath." (Mashiro)

Mashiro licked a bit of cream off her fingers and headed for the bathroom.

As if imitating Chisome, she has also begun to actively help with the housework; but I can't help but feel like she has become as if able to act somewhat apart to some extent from Chisome.

"That Mashiro......she's really become human-like isn't she."

"Un. This is all thanks to Nii-san as well I think."

"That's too much credit."

"That's not true."

No, it's really too much credit you know that is.

I didn't particularly intend to do anything special anyway, and the fact that she changed like that is definitely proof of Mashiro's growth.

"Nii-san should a little more, realize his own greatness I think?"

"......Was that so?"

"That is so. Ei ei!"

"......This little"

I tried to get back at Chisome who poked me in the cheek *tsun*tsun*, but she grins and smiles; comes and jumps at me.

It was an instant thing, but I caught her and moved to the position of the sofa as it is.

If anyone were to ask what kind of playfulness we had at this age, and if someone were to see it, they would be amazed, but at the end of such playfulness an accident happened.

"e?"

"a......"

Chisome slipped her foot and ended up losing her balance.

I reached out my hand to support her, but even though I could put my hands on her back, I couldn't hold on and we both ended up just falling down together as it is.

It just, fortunately, because we fell onto the sofa, neither of us got hurt......but the problem wasn't that.

"......"

"......Nii-san"

In the beat of falling, my hand touched her chest.

Because it was sudden, I ended up stopping moving, but without realizing it, I felt strength in my palm and my fingers sank slightly into her plump bulge.

"M-My bad!"

I hurriedly let go, but Chisome giggled.

"Nee Nii-san, isn't it about time? I think we've already developed a lot of love though?"

"......That is――"

"What, are you doing?"

Chisome and I were staring at each other, but what resounded there was Mashiro's voice with no intonation.

Apparently, it seemed that the bath was ready, so she came back; but when she saw me in a way as if pushing Chisome down, she muttered quietly.

"......After all, Onii-sama likes oppai. I'm big like Chisome too you know?"

For the time being......I thought I shouldn't let the pure girl say any more, so I separated from Chisome.

After that, I headed to the bath, but recently I have something on my mind.

In any case, Chisome is important to me, and I did treat her like a treasure; but since the distance is also close as it is, considerably the number of times I get turned on has ended up increased.

"......Haa"

While thinking that this got me, I also thought that because there is such a charming girl close by it can't be helped right.
