Niece 6 Exterminate

Mo, momoko?……tte, don’t tell me, it’s that Momoko!? Only one person comes into my mind. But, she shouldn’t be in this place……
「What are you doing! If you don’t open when I count to three, I will report that you are a hentai lolicon man who will kidnap all little girls!」
「Uwa! I will open so wait, waitt!!!」
When I open the door in panic, it’s unmistakably Momoko who was standing there. I don’t meet her for a while so she seems to have grown up, but that bold personality doesn’t change. That reminds me, she was already a middle schooler. That explains the uniform.
It’s late to say, but she’s my 「cousin」 Momoko’s father, in other words, my uncle, had only one daughter so he wanted a boy all the time.
From around the time Momoko became conscious of what’s going on around her, she said she wanted to marry me half jokingly, no, at a relatively serious level.

So, a serious marriage with Nana-chan who is my niece is impossible legally, but it’s possible if it’s with Momoko.
To me, that was also a considerable fear.

「Momoko, why are you here!?」
「Etto, I was asked by the sisters to look after the nieces! It seems difficult for nii-chan alone. But, in fact, I wanted to come so I asked them to bring me along together」
I thought that she would keep a little distance when she became a middle schooler, but this is the result. I’m happy that she’s still emotionally attached to me even now, but it’s annoying that it’s getting out of hand, honestly, since I could be intruded on, I couldn’t feel any merit at all. In the first place, there’s no s.p.a.ce for another person to live in this room.
Momoko sensed my hard-hearted face, she arbitrarily took off her shoes and entwined her hand with mine.
「You don’t need to feel that annoyed you know?……Hora, the money to take care of the niece from sisters, I was in charge of it, you know? I also received some from papa…..a total of about 200.000 yen」
What!? If it’s that much then it’s just about the balance. (それだけあればお釣りがくるぐらいだ。)
My face unintentionally broke into a smile, I rubbed Momoko’s shoulder lightly and went up to the corridor.
「We are doing really good」

「Onii-san, that woman, who?」

Na, Nana-chan!!!
Her “already in yandere mode” piercing gaze hurts!
Furthermore, for some reason, the naked Nana-chan is dragging my job hunting along white shirt while wearing it. (なぜか奈々ちゃんは素っ裸に俺の就活用ワイシャツを引きずりながら羽織っている) The front was opened so her nipples and v.a.g.i.n.a were in full view.
「Etto, I’m onii-san’s cousin, Momoko. I came to take care of everyone. What’s your name?」
「……Nana」
「a, I remember! I came to see when Nana-chan was born, so I also changed your diaper, you know?」
The pretence talk which is somewhat friendly-like doesn’t enter Nana-chan’s ears.
Nana-chan ignored and didn’t answer, she then forced her way to the s.p.a.ce between me and Momoko and demanded a hug.
When I hug her, she puts her face close, bites my earlobe and whispers.
「Onii-san, it’s, already……out! I called mother, about you kissing me forcibly」
For, for real!?……It was already over, my life.

*Gacha*!

The door of the room opens It’s Akira-chan who opened it. I’m somewhat fl.u.s.tered.
「Onii-chan, I will wash my pantsu myself after all! Because, what I did……was bad」 (だって自分が‥‥したのに悪いもん) 
Even to Akira-chan who doesn’t understand the flow until now at all, the yandere-mode Nana-chan bares her fangs (in a sense).
「Akira-chan, that’s not bed-wetting, it’s onii-chan’s baby material. He really want to do ecchi thing to Akira-chan so it couldn’t be helped」
Nana-chan, you said that too!? But Akira-chan didn’t understand anything, only the keyword 「Ecchi thing」 went around her head and she became panic.
「Baby……material? Ecchi,……thing? That means, Onii-san wants me to be his bride? Because, I can do ecchi thing only with the person I will marry, sensei…….said……e……..eh!?」
Akira-chan whose face suddenly became deep red rushed into the room.

「Nee, nii-chan. I don’t understand well, but you didn’t do a realllly terrible thing, right? If so……that cheating insect-san, should I exterminate it?」
That moment, I felt like Momoko’s expression changed to that of Nana-chan.
Are, didn’t I hear a similar line somewhere?

And Nana-chan is Nana-chan,

「Onii-san, you had the cheating insect-san before Nana was born, right? Like Akira-chan a while ago, I wonder if I have to “exterminate” it?」(おにーさん、奈々が産まれる前からうわきの虫さん飼ってたんだね。)
