Sorry chisa here.
I will be translating this for a change of pace and the chaps are short~
Also it reminds me of this omegaverse manga I like ( which ended just the other day!) It’s called, Sayonara Alpha < i="" rec!!=""  i="" think="" it’s="" being="" translated?="" tho="" this="" one="" isn’t="" omegaverse="" and="" sa="" isn’t="" incest="">
Anyway this is serious incest shotacon so I’m warning you lol
And I haven’t told it yet to shizu since I just did this now in a whim lol. Idk if she’ll edit but, I’m warning coz I translate like 80 percent literally? So I guess unlike, otoko darake~ this will only have the level of my eiken 2-kyu (taken years ago lol) so please correct my grammar mistakes and such XD

EDIT: Shizu hereeee, I edited it Owo This story is too cute 

My heart wouldn’t rest as my younger brother looked up at me with his innocent eyes.

My shameful body responds just by changing his pajamas. I’m getting dizzy.

My brother is still 5 years old. I’m in high school. My younger brother, who is 12 years younger than me, cannot not be cute.
I wonder why. A, I actually a boy-loving pervert. In short a shotacon, that is.

My heart hurts. I’m scared, I’m scared and I can’t help it. Why my brother? If it is just boys, there’s a lot of them in kindergarten. I have never experienced this feeling before.

I’m a.s.signed to the task of sending and picking him up from kindergarten. Also changing his clothes. The fingers unb.u.t.toning his pajama shirt are shaking. Today, I am being tormented again with these painful feelings as I change his clothes.

「Nii-chan¹, you look sad.」

My younger brother clings to my neck.

「I love Nii-chan so, I don’t like, if Nii-chan is sad.」

Looking at me with teary eyes. You don’t even know what I’m thinking.

….Aaahhh, oh no, so cute. It’s because you’re this cute that it can’t be helped.

That silky black hair, those big eyes, a small body that smells good anywhere.

It’s all because you’re so cute, that I fell in love with you.

「Nee, Nii-chan.」

「Hm?」

I was kissed lightly on my lips. It tasted like sweet milk. It’s because my brother drinks his milk with sugar. No wait, I mean..

「Wha….」

「Cheered up now?」

「Where did you learn this kind of…」

「It’s a charm to cheer people up!」

My brother smiled brightly. Your brother is now cheerful in a different place²………

「Do you like your Nii-chan?」

「Mhm, I like!」

I helped him change into his kindergarten uniform, stood up, and held his hands.
The hands holding mine was warm.

I locked up my romantic feelings at the depths of my heart. Today, yet again, I will send and pick you up as your older brother.

I won’t do anything so, please just forgive the fact that I love you.  Until the day this feeling disappears on its own.

¹Nii-chan >> lots of you probs know but it’s older bro. Idk how to translate a cutesy way to call your bro lol so i left it like that

²Oh my G.o.d O.O yes he means that way. He said genki which is used for energetic too.

If you’re wondering, yea otouto-kun is still 5 and his words are still that of a child so I tried doing it like that lol.
