A/N: Mini oneshot.

It's late in the evening. Our parents were away for a long mission at the neighbouring village. I've just finished my own mission for today. My body felt sticky and I'm drained. Really in need of a nice hot bath, a good meal and a good night sleep.

But something kept bothering me. Some sound, to be exact. "Is it my breathing?" I immediately held my breath in my chest. The weird sound continues. The dark living room unexpectedly gave me a creep. I slowly get up and walk to the staircase. And some thought kicks in. "It can't be..." I frowned. Some silly thought came into my head. So, slowly I went to his room.

The sounds just get louder. "What the..." I mumbled as I realised the door was slightly open. I wanted to go away but some part of me wanted to stay. Stay and enjoy...listen. "Mm...ahhh...ahh..haahh..." -was all I can hear-. The hair behind my neck stood up, I don't know why. Rush of blood pumped in my vein throughout my face, maybe in nervousness or excitement.

"Fuck! Itachi is fucking!", I thought to myself. I moved closer to the door and peeped inside. My vision was blurry because of the darkness in the room. My pervert part really wanted to see their act; their movement and their intimation -to be exact, my brother's movement.

Gradually my vision adjusted to the darkness, I could see my brother and her girlfriend having their time on the bed. Itachi positioned himself at the side of the bed while he lifting the girlfriend's hip a bit allowing himself in. I gulped. "Haahh...ahh...ahhn..." followed with each thrust he made.

As I continue peeping at my brother's sex making, I vividly remember Itachi's girlfriend from her visit to our house last week. Her name is Risa. She is the same age as Itachi, and a daughter of the fabric merchant. She is not much, just fine. Makes me wonder why my brother likes her, although she does have fine curve. And that body curved well under my brother, taking in the pleasure.

"Umm...shit..." I suddenly realise that my own 'little brother' has grown up a bit inside my pant. The moaning and grunting in the room make me a little bit 'hard'. Now, I'm jealous of Itachi, as I'm still single. Maybe, I should be more open to Sakura next time.

Risa's moan gets louder and I could hear them both breathing hard. The creaking sound of Itachi's bed hitting the floor and wall are also heard. "Damn Nii-san..." I thought, not realising that I slowly stroke my own bulge. I almost forgot that I actually peeping on my own brother and not watching porn that Naruto sometimes brought me to watch together on Friday night.

Itachi then pulled her hip closer and thrust faster than before. "He's at it..." all the words I uttered accidently slipped through my mouth. I don't even realise that I said anything at all. And even my hand stroked mine faster.

"Aghhhhn..." Risa moaned louder than before and they panting and kissing and hugging. Everything they do in porn that I used to watch. I too, squirt...a lot. As fast as I could, I make way to my room next door. I gasp a little and cold sweat run down my body.

The next hour, I stayed in my room ignoring everything outside. I took my bath and jerked again in the tub, imagining things. When I'm sure that my brother is done with his business, I went out.

"Nii-san..." I called out to Itachi. He's having leftover from yesterday dinner. He looked at me with his usual smiley face. "Come, join me" he calmly state. I nodded and sit across him. Lots of thing I wanna ask him right now, but I just zip it in.

"What's wrong?" he suddenly asked, seems like he could saw all the thought lingering around my head. I almost choke on my rice ball but kept my cool. "Umm... Nothing. Why?" I put on my usual stoic face, though I know that my eyebrow furrowed a little. "It seems like you have done something wrong" he said. I only could stared at him.
