GUYS, I went with the lemon. SORRY THIS TOOK SO LONG TO WRITE, I had school and a lot of homework but I will try to make sure that this doesn't happen again. No lemon in this chapter as it just gives context, no point in writing a lemon without a story….right?

Disclaimer, I don't own Vocoloid or Naruto, which gets something of a cameo at the end.

Anyway, onto the story.

Len's POV

"imouto-chan, are you ready?" I asked my younger sister, Rin, it was our birthday today and we were going to celebrate.

"Nearly, just give me a sec" she replied as she walked into the bathroom

"Ok…wow, out of context this conversation would sound really dirty" I muttered under my breath

"What was that?" my sister poked her head out of the bathroom, having fixed her hair.

"Nothing"

"You just said that out of context this conversation would sound dirty."

"Why ask if you already know the answer?"

"Because that way I learn what you look like when you lie"

"Ready now?" I asked

"yeah, let's go" she replied as she walked out the door, The dress she was wearing was tight, black, frilly and short, damn she was cute, no one could know that I thought that way though, she was my sister for god's sake. At least I had my own perverted fantasies. I'll tell her how I feel tonight after the party

Rin's POV

We walked over to Luka's house, she had decided to have the party at her house because she said it was "your birthday so you shouldn't need to organise anything or clean anything up." She was the best friend ever and had done everything; we just needed to show up. I wasn't going to be able to thank her enough for this. I looked over at my brother as we walked; damn he was hot in his black, high-collared shirt and jeans; my brother was hot in general, I know that it's not right for me to think about him like that, but still, I fantasize about the day when he will take me in his arms and put me on a bed. I'll tell him how I feel tonight after the party.

"What are you thinking so hard about?" Len asked

"How we are going to thank Luka for organising this party"

"I've got a few ideas…" he replies as he knocks on the door

~~~2 hours later~~~

Len's POV

"I think Rin's drunk" Kaito warned

"Fuck…" I replied, Rin was normally cute and fun, but when she's drunk she is scary as shit. All of a sudden someone jumps into my arms; I'm going to kill whoever spiked Rin's drink, it was probably Neru.

"Ne Lenny-chan, let's go dance" Rin beckons

"Ok, but first you need to tell me if you drank anything that tasted funny"

"Coke okey okey"

"Did you see anyone put anything in it?"

"Neru put something in my okey coke"

"I thought so… we need to get you home"

"But I wanna dance with my onii-chan" she said as she gave me a dangerous look that said I didn't really have much of a choice

"Ok, one dance and we'll make it special" I said as I walked over to the DJ and made a request.

Kabosoi higa kokoro no hashi ni tomeru
Itsu no manika moehirogaru netsujou
Watashi no chou fokisoku i tobimawari
Anata no te ni rinpun o tsuketa

Our favourite song started playing as we started to slowly dance, swaying from side to side

karamiau yubi hotoite
kuchibiru kara shita e to
yurusaranai koto naraba
naosara moeagaru no

She leaned in closer to me, obviously enjoying this dance, and started to hum along to the tune. She smells so good.

Dakiyosete hoshii tashikamete hoshii
Machigai nado nai n da to omowasete
Kisu o shite nurikaete hoshii
Miwaku no toki io yoishire oborete itai no

I twirl her around and pull her back closer to me

Sokubaku shite motto hitsuyou to shite
Itoshii nara shuuchaku o misetsukete
"okashii" no ga tamaranaku suki ni naru
Ikeru toko made ikeba ii yo

Mayoikonda kokoro nara

Kantan ni tokete yuku

Yasashisa nante kanjiru

Himanado nai kurai ni

kurikaeshita no wa ano yume ja nakute

magire mo nai genjitsu no watashitachi

furete kara modorenai to shiru

sore de ii no dare yori mo taisetsu na anata

We dance faster to match the beat of the music, twirling around and around.

yoake ga kuru to fuan de

naite shimau watashi ni

"daijoubu" to sasayaita

anata mo naite ita no

dakiyosete hoshii tashikamete hoshii

machigai nado nai n da to omowasete

kisu o shite nurikaete hoshii

miwaku no toki ni yoishire oboretai

I decided that I wasn't going to get a chance better than this

hikiyosete magunetto no you ni

tatoe itsuka hanarete mo meguriau

furete ite modorenakute ii

sore de ii no dare yori mo taisetsu na anata

I leaned in close to her ear and whisper "I love you Rin, more than a brother should"

Rin's POV

hikiyosete magunetto no you ni

tatoe itsuka hanarete mo meguriau

furete ite modorenakute ii

sore de ii no dare yori mo taisetsu na anata

I am dancing with my brother, I am dancing with my brother, I am dancing with my brother, he smells so good, I need to tell him I love him, why can't I get my thoughts together, why am I thinking like this? Slow down…deep breaths…wait, what? Did he just say that? I must be hallucinating, why do I feel so funny? OH MY GOD, I need to say something

"I love you too, onii-chan" I whisper to him. Wait, what was I thinking? We're siblings, but that doesn't matter if I love him…right?

Len's POV

She whispered back, she loves me back.
"We're going home now, and I'm going to show you how much I love you" I whisper in her ear as the song finishes and we take a bow. I say thank you to everyone for coming to celebrate, and say thank you again to Luka for hosting the party, I'm going to need to find a way to thank her, maybe I'll ask Rin to see if she has an ideas, or see if she agrees to the few I have.

As we start to walk home, Rin was too drunk to walk, so I had to carry her on my shoulders. This wasn't the best idea I'd ever had as she started covering my eyes and pulling my hair. When we get home, I say to myself, I'm going to show her how much I truly love her.

And that's the first chapter, I hope you liked it, sorry there was no lemon in this chapter if you were hoping for it. I tried to make it more cute and meaningful then "hey Rin, Let's have sex", I hope it worked. I was watching Naruto while finishing this because I find it difficult to work on something like this without a distraction, that plus it's fun to try to type and watch something other than the keyboard or screen.

Will Len show Rin how much he truly loves her?

Will this get rejected because I used the full lyrics of a song?

Will Naruto bring Sasuke back to Konoha?

Find out these and more (accept for the Naruto bit, I don't do spoilers) in the next chapter of "A special Kagamine birthday".

Yep…never doing that again…

Silence, out.
