Disclaimer: I don't own One Piece!

This be LuffyAce. It starts out as fluffy, but my goal is to make it hardcore incest. xD So beware for the yaoi incest omgzomg ahead! Or then I fail at life and cuteness prevails. We'll see.

Ace felt like he had never had the opportunity to be a child. Mostly because in between his so-called father walking out of his life and Garp forcing him into situations even adults had difficulties finding a way to survive, he had to look after his baby brother.

And while being abandoned by that rotten man did leave him a bit vengeful and bitter, and even if facing ordeals of life and death cut his skin and broke his bones, they had nothing on Luffy.

Not to say that he didn't love the little pain in his hide. But the boy was gnawing on the shortening string of sanity Ace had left.

"Ne ne, Ace! Tell me!"

A ten year old Ace sighed and slumped against the table, looking at Makino for help. She just shrugged and continued on with her mission to wipe the table sparkling clean.

Shanks was sitting not too far away, trying hard not to laugh.

"Yeah, Ace. Tell us!"

And he found himself pouting because this was one of those things they should not expect a child like him to do.

"I keep telling you Luffy. Pirates bring strange things from the Mystery Island, babies included!"

And the whole bar exploded in laughter, all of Shank's dirty pirates joining in to mock his answer. Even Makino chuckled. He and Luffy were the only ones not amused. While Ace groaned and kept banging his forehead against the wooden table, Luffy stared at him, mouth wide open before he smiled as if he finally got it.

"So it's a mystery!"

By now, Shanks had already fallen off his chair and was rolling on the dirty floor, at least giving Ace the satisfaction to see his white shirt being dirtied by whatever it was that had dropped on the floor.

Luffy was paying no mind to anything what was happening around him, too filled with curiosity to concentrate on anything else.

"Ne, Ace!"

Ace turned to look at his brother, his forehead slightly throbbing. "What?"

"When we become pirates, we can go there and get our own baby!"

The bar fell silent, if you ignored the couple of badly concealed snorts and giggles coming from here and there. This was the last time, Ace swore, that he would be at the bar while it was filled with these good-for-nothing pirates.

"Why with me?"

Luffy looked like it was obvious why he wanted a baby with Ace and rolled his eyes as if his big brother was dumb.

"Because we're a family."

This time Makino was kind enough to pipe in on their conversation, smiling gently at Luffy as she spoke.

"Luffy, usually you fall in love with a woman and start your own family with her."

Luffy blinked his big eyes, looking confused. Mostly because he had no idea what women had anything to do with this. The only woman constant on his life was Makino, and that was because she attracted him to her with food. Other than that, there was just Ace and granpa. A family full of males.

And while he didn't care for granpa, that ruthless old man, Ace was the world to him. And it was with Ace he had shared his whole life up till now. It would only make sense that he would have a baby with Ace as well.

With an angry pout on his face, he glared at the pub keeper and latched himself on his big brother's arm, shoving his tongue out at her. "No, I want Ace!"

Somehow Shanks had crawled his way through the filthy floor right next to where Ace was sitting, the red-haired man still twitching from his belly-cramping fit of laughter. The smile was still wide and full of mischievousness when the man opened his mouth to speak.

"Hey Ace! I thought I should tell you to use rubber," the man was laughing already, finding his oncoming joke too funny to form into words. "But then again, his whole body is rubber!!"

Again there was an explosion of laughter and someone choking on his meat on the background. Ace felt his cheeks heat up from both anger and embarrassment. No one liked to be made this much fun of, especially if you were only ten. But the adults kept on laughing and Ace felt like he had had quite enough.

He stood up from his chair and started to walk away, his destination home, trying his best to ignore the laughing pirates as he went.

Really, this was all Luffy's fault, he fumed. If he had asked those questions in the safety of their own home, or better yet, from an actual adult, he wouldn't have had to go through being made fun of so much.

His brother was nothing but trouble and head aches and Ace decided he would punish the boy by not talking to him for... for a week at least.

But then he heard Luffy run up to him from the bar, still in high spirits as if he hadn't been made fun of at all. Ace felt his hand being grabbed by his little brother's warm fingers, and didn't have the heart to pull away from the touch, no matter how pissed he had decided to be.

Luffy was still grinning from ear to ear, humming to himself as they walked towards home together, and somehow Ace forgot his pissed offness and decided to show mercy by canceling his threat to not talk to the boy.

"Luffy."

"Huh?" the boy didn't look at him, but kept on waving his hand in front of him in the rhythm of whatever it was he had been humming the moment before.

"Why do you always ask me about those kind of things?"

The grin Luffy offered him was almost enough to split the boy's face in two. Ace would have been worried had the boy not been made out of rubber.

"Because Ace knows the best!"

His baby brother's response made a small blush crawl on his freckled cheeks, followed by a large grin of his own.

Sure, Luffy was slow at thinking and quick at disasters, but he was still Ace's little brother. Cute and talkative and hella annoying.

"So what do you think the One Piece is, Ace?"

"Hmm, it's a mystery."

"A mystery? I see!"

Ace might have been forced to grow up faster than he would've liked by his father and his father's father, but Luffy was enough a child for both of them, and as a responsible big brother, it was his duty to make sure Luffy stayed that way. Adult or not.

End.

They make me happy as a fangirl. ;w;
