Boku no Meikko wa Yandere deshita Chapter 9

Niece 9 Marriage partner

It’s not a cry, definitely a 「whisper」.
That trembling with fear voice……is Yoko-chan’s, without a doubt!
When I hurriedly jump out from the box, the box in front of us where Yoko-chan enters was, for some reason, opened a little. And, in front of that gapーー
「Oi you, what are you doing!!!」
There was a pervert lolicon man masturbating using Yoko-chan’s urinating scene in real time as side dish..
「Uwa! Sss, sorry! I haven’t come! Please let me off!!!」
The man became fl.u.s.tered and touched his own pocket, held out all of his money.
It’s not good to chase him and hand him over to the police. Besides, if I do such a thing, it could also hurt Yoko-chan more.
The handed money is nearly 50.000 yen. With this, I’ll buy something she likes.
「Yoko-chan, are you okay!? It’s scary, right? Sorry for not noticing」
Yoko-chan still sits on the toilet seat while her whole body is trembling and her eyes are teary. When she was shown that thing and was 「Haa haa」’d, perhaps she couldn’t move because of fear and bad feeling. (sfx: breath heavily while masturbating) 
「uu……thanks for helping, onii-san……but, it was scary and I couldn’t pee……」
「a, sorry!……Then, this time I will hold the duty to stand guard in front of the door, so don’t worry and finish it」
When I’m going to close the door, Yoko-chan holds my hand and restrains it.
「Gusu……you was together with Asari-chan, right?……Unfair. Me too, unless it’s together with Onii-san……no way (yada)」
I thought Yoko-chan was the most unyielding and mature, but her inside was not different from everyone after all, which was appropriate for a cute little girl of her age. Perhaps, she becomes too timid because of the matter a while ago.
「I understood. I will be with you all the time」
When I nodded, Yoko-chan still grasped my hand like that and finished her business, looking embarra.s.sed.

After this and that, the three of us, feeling refreshed, return to our seats. Then, Momoko and Nana-chan still quarrel about various things as usual with a smile, only on the surface.
「Nii-chan, welcome back!」
「Onii-san, this time, take Nana to the toilet too」
「a, that reminds me, Yoko-chan……isn’t it? A while ago, you said you would decide Nii-chan’s marriage partner, right!? I and Nana-chan, which one do you think is good?」
「T, that……」
Yoko-chan averts her face which became bright red and mutters bashfully.
「T, that, Onii-san’s marriage partner……I’m good, I think」
Taking advantage of that relatively serious-like shocking confession, even Asari-chan got on. (わりとガチっぽい衝撃の告白に便乗し亜砂里ちゃんまで乗っかってきた。)
「Asari-chan will marry Oji-san too! Because he’s kind, and it’s not scary after we pee together!」

ーThat moment, the frozen Momoko and Nana-chan’s sharp eyes pierced me.

「……Nii-chan, what did you do in the toilet this early morning? Do you want to ○? Nee, you want, right?」 (it’s ○にたい in the raw, 死にたい-want to die, maybe?) 
「Onii-san, Looks like you want to anger Nana, right? Perhaps, are you 「Do M」-san?」 (extremely m.a.s.o.c.h.i.s.t)
