The Ninja World, with a twist. Naruto has a twin and so does Kiba! Takes place in Shippuuden, no real plot yet.

"The room was dark, and the only sounds that could be heard was coming from the two teens.
"Ah, S-Sasuke" The girl moaned softly in his ears. The boy 'Sasuke' was currently holding the girl by her waist and kissing down her neck. The boy smirked and continued doing what he was doing.
The girl was sitting on him with her legs on either side of him."

Nasuma listened to what Kemiko was narrating along with Naruto and Kiba who were with them.

"And then she whispered to Sasuke, ever so gently. Fuck me," Kemiko grinned.
"That did SO not happen! Like for real... Kemiko that's horrible.!" Nasuma laughed. "You don't really think I did that with him when we played Seven minutes in heaven last night !"
"My innocent sister!" Naruto complained.
"Chill out Naruto. Who would want to do your sister anyway? She's uglier than Medusa just take a look for yourself." Kiba remarked shrugging. But little did he know ... The fire in that girl's eyes. Nasuma looked over "Take that back Mutt!"
"How can you say that about my wife?" Kemiko yelled dramatically gasping. Akamaru just sat there watching the bunch.
"Well it's true. I can't see what Sasuke of all people saw in that thing."
"Your just jealous of her good looks believe it."
"Believe what?" Kiba groaned.
"Pasha..." Nasuma commented.
"Dango" Kemiko commented.
"That sounds good about now, UNLIKE SOME MUTS"
"Blondes." Kiba rolled his eyes.
"HEY WHAT ABOUT US BLONDES?" The twins yelled.
"Kibbles, your digging yourself a bigger hole... And I don't think me and Akamaru would want to get you out..." Kemiko stated smiling. Kiba rolled his eyes. "Whatever, sis." Naruto sighed. They always fight. Naruto and Kemiko don't fight but their sibling do, all the time.
"So are you going to Hinata's sleepover? It's her turn to host," Nasuma asked to no one really, except for Kiba. No. Not asking him.
"Oh yeah! I plan the win that poker game. Damn Neji" Kemiko cursed.
"He had such a poker face too!" Nasuma stated. "You couldn't tell what he was thinking!"
"You weren't even playing," Kiba remarked.
"How would you know Mutt."
"I was playing as well. And we all know your to stupid to even understand the game. So there. I'm going home, come on Akamaru." With that Kiba left to his house Akamaru following his master.
"Ugh he's just an asshole" Nasuma rolls her eyes.
"Haha... Oh.." Naruto scratched his cheek. "How did this start anyway?"
"He called her a useless girl. And from there... The fighting was born..." Kemiko answered.
"Oh yeah..."

Back over at the academy the children were outside for recess. Outside there stood a big old tree, reaching the sky and maybe the clouds. The kids weren't sure. In the tree there laid a kite. A bright red kite that laid there entangled with a branch.
The young boy who owned the kite looked up.
"It's stuck." He frowned and tugged the string. "Stuck." He stated again tugging it again lightly, not wanting to break it.
"I'm hungry..."
"!" The blonde haired girl crashed in to him hugging him, though it could be argued it was a tackle.
"Oh hey Nasuma!" The boy responded. "How's it going?"
"Orangetastic!" She smiled. "And you?"
"My kite got stuck," he pointed up to it.
"I can get it!" Nasuma smiled proudly as she got off him and helped him up.
"Really?"
"I can try can't I?" Choji sighed "Yeah."
"How did you get up there anyway? It ran away?"
"It felt like the air took it."
"Oooooohhhh. Okay!" She grinned. She looked back up at the tree. It's a really big tree. Then looked at the kite.
"Come to me kite!" She placed her arms out and waited. Choji just stared at her. "That's not Ganna work"
"It does in the comics!" Choji sighed again.
After many failed attempts at the kite they stopped.
"It's impossible..." Nasuma groaned.
"My kite hates us..." Choji sighed... "I'm really hungry too... Go climb the tree."
"My hair will get stuck!" Nasuma's reaches her belly bottom, almost.
"Hey Choji, how's it going?" A brown haired boy asked.
"Oh hey Kiba" Choji waved.
"What's with the kite? This girl got it stuck in there?"
"No I didnt!" She defended herself. "I was trying to help." While she defended herself she didn't notice Kiba go up into the tree and untangle the kite. However she did notice him jumping down.
"There,"
"Thanks man!"
"No problem"
"I could have done that..."
"Then why didn't you?" Kiba asked.
"Cause I would get my hair stuck..." Kiba rolled his eyes."Useless"
"What was that?" She asked making sure he didn't call her that.
"I said I'm calling you Useless, baka."
"Who are you calling useless, mutt!" She pushed him. "No one calls me that!"
"Cause everyone knows that!" Kiba yelled at her as he got up. "Useless." He pushed her. "Baka" he pushes her again.
"Um... Guys" Choji attempts to get then to well was
"Don't touch me you ! You... You dirty Mutt!" She slapped his hand away. He pushed her down.
"Look who's dirty now." Kiba smirked. Nasuma looked up and pulled him from his legs and punched him.
"Yeah you!" Nasuma smiled. After that the fighting continues, with insults, scratching and punching.
Moments later...
"Let me at him! Naru let me go! Let me at him!" Nasuma complained as she tried getting free from her brothers grip.
"Useless Baka!" Kiba on the other hand was held back by his sister.
"They fight to much..." Choji sighed.
"For how long?" Kemiko asked.
"Dirty Mutt!" Nasuma screamed.
"Dunno" Choji shrugged.
"How did it start?" She asked again.
"Stupid Demon!" He yelled. Nasuma twitched. Naruto did as well. Kemiko looked at him. Naruto let go of his sister. And there the fighting continued. Kemiko backed away.
"Stupid kibbles deserved It."
"Mhm, believe it." Naruto nodded in agreement.
"Hey... Shouldn't we stop them before they kill each other?" Choji asked. "Guys?... Guys... Oh whatever... I'm hungry..."
