My niece was a yandere

We'll control you

---

"N…no, it's fine!! It’s still cold so you don’t have to take off the futon!"

Of course, I said that in an agitated manner so Momoko-chan and Nana-chan begin to be suspicious.

"Did you have to say that out loud? Onii-san, you are hiding something?"

"Nii-chan, there’s no way you’re hiding something outrageous from me, right?"

Th...that’s true! So please, don’t remove the futon!!

--However, these two who are not only heartless but with the same interest are now working together to expose my secret.

"Okay? Nana-chan...let’s pull nii-chan’s futon as hard as we can!"

"Uhm, I understand."

No, this is the end!!!… Goodbye me.

「Pull」

After the futon was pulled out vigorously reveal Akira-chan whose face was now completely red with tears as she tried to suck my thing to its roots appeared…!

I'm unwilling but to give in for these women to discover and to be honest, being seen by Michika-neechan and Reika-san is not the end of the world!!!... But,

"Kyaa! What, what is happening”

"AAAH!?, what, what's wrong"

All of a sudden, Makoto-chan and Asari-chan jumped behind and blindfolded both of them. Nice!!!

They urged them to go outside while holding their eyes from behind. Moments later, they kicked them out without knowing the reason.

I don't know if it was clever or not but I told them accordingly.
“I...I'm sorry but everyone seems to be playing something new... so can you wait outside for a minute?”

Then, Reika-san who senses the situation seems to be apologetic.

“Ah, um, if that's the case, I'll... go back for now, but I'll come back later…”

But that isn’t true for Michika-neechan. She becomes more upset as she bangs the door forcefully.

"What’s wrong, Yuu-chan!? I don’t remember raising you like this! Hurry up and open the door!"

"Mi, Michika-neechan, do you remember the family restaurant in front of that convenience store where we met yesterday? Can you wait there? I will go there as soon as possible!"

She didn’t seem to be convinced, but she agreed to my pressing words with a weak, small voice

"I understand. But Yuu-chan, you know that onee-chan can succumb to loneliness easily so come meet me... as soon as you can, okay?"

--Finally, I've escaped a bad end, but the fact that these girls discovered this situation... is still a death sentence for me.

"Nii-chan, do you know what you’re doing…? You know that this is a dangerous crime, right? Do you really want your life to end right now?"

"...Mou, Onii-chan, it seems you need to be [], aren't you"

Needless to say about the other two, and Youko-chan also tries to gather herself together as she draws back.

"Cough! Cough...! It was really painful, but this is baby material, right? The more of it comes out, the better it feels. isn't it, Onii-chan? do you happy?"

It would’ve been delightful if I wasn’t in this situation! Akira-chan’s face is sticky with the disgusting fluid. I am still unaware of how to deal with this situation and while I'm still erecting from all that stimulation, therefore, I jump off the loft and kneel down on the ground in front of everyone.

"I’m…I’m sorry!!! I want to say that I’m sorry, I’m sorry, I’m sorry!!"

I can't think of anything to excuse for this crime so all I can do right now is to be honest and ask for forgiveness. Even if they don't accept it at all.

However, Momoko calmly smiles and says some rather unexpected words.

"What should I do? Well then, I can’t let this hentai Onii-chan do whatever he wants. So he needs to have someone like me to control him then."

"That‘s unfair, Onee-san. Onii-chan is Nana’s future husband so Nana needs to take good care of him."

And then, Momoko-chan let out a delightful smile which is far more than a simple smile or even surpasses the "bizarre" level.

"...Even so, it wouldn't be fair if only two of us control onii-chan alone so should we let the other nieces control him in the way they like?"

Wh, Why? Does anyone even know what it means in....

But, no matter how old the woman is....For example, young girl, there would be a "woman" in it. So Asari-chan, who understood the meaning behind that, is the first one to declare with a cheerful voice. (P/S: 幼女 is young girl and "女" is woman)

"So then, Asari will control Uncle's playtime then! From now on, Uncle must not play video games and cards without Asari!?"

this has already turned into a first come first serve. Asari-chan's way is cute but from now on, let's see how will the other girls escalate it. The next one to raise her voice is Youko-chan.

"Then I’ll be controlling Onii-chan's bedtime and bath-time. And if Onii-chan goes without me then…."

Youko-chan, you don’t have to say anything more than that!

The next declaration is from Akira-chan.

"Cough! Cough!! I have swallowed lots of onii-chan's baby seed... From now on, onii-chan must give all the baby seed to me, and if you don’t..."

Aaaaah!!! Akira-chan, I understood so please don't say anything more than that!

As if surprised by the declarations of the girls, Momoko announced directly.

"Ah! Then I’ll control nii-chan when you ***! And you must not do it by yourself, okay? So if you really want to, you just need to say it to me, do you understand? And if you do it yourself…"

Stop already, I'm out of willpower so you don't need to say it.

....To make things worse, Makoto-chan declares her way with a completely different tension compared to the other.

"Ano, I... I will be in charge of caring for onii-chan. From meals to..."

Aa, at one time, I feel like Makoto-chan seems to be more abnormal than Nana-chan but I was relieved after hearing that. Come to think about it, Makoto-chan is really good at housework and cooking.

"Therefore, Onii-chan must drink my miso soup with my blood mixed in it.... and also, I'll monopolize from your smell to your taste, from your shirts to your underwears.”

Y, yikes...Makoto-chan really titled into a yandere path herself.

--And of course, needless to say, Nana-chan declared her simple yet powerful statement.

"Then, Nana will control Onii-chan “cumming” then, if Nana does not agree then onii-chan should never cum".

Panicked, Momoko raised her voice after hearing that.

"A-Aah!! That’s way too unfair! Doesn’t that mean even if I control onii-chan ***, he wouldn't let it all out without Nana-chan's approval?!"

"Onee-chan, isn't it too late to say something like that? No matter what and who does it, onii-chan must not release it without Nana's approval... And if onii-chan breaks your promise then mother... will become too angry that she will cry... and that would become a big problem for onii-chan, wouldn't it?"

My, My existence is at these girls' mercy from now.

And above all of that, "that" is waiting for me tomorrow----.
