DISCLAIMER: Unfortunately, I don't own Naruto or any other characters in the show. Even worse is that I don't get any money for this, either.

So... let's say that Naruto and Sasuke are 6 and Itachi and Kyuubi are 11?

Chibi Naruto and Chibi Sasuke were outside, laying on the ground. It was a full moon and the stars were all bright and shiny. Naruto was delighted, Sasuke's house was always the best place to stare at the sky.

"Hey Sasuke," Naruto said lazily, suddenly remembering something his brother said.

"Hm?"

"We're best friends, right?"

"Yes."

Naruto rolled over and touched Sasuke's lips with his.

"What are you doing?" Sasuke asked, pulling away.

"Kyuubi said that it's okay to kiss people that you like and are really close to. You're my best friend, and nobody is closer to me than you. So kissing is okay, right?"

Sasuke thought for a second. It did make sense... "I guess."

"Good!" With that, Naruto leaned in and lightly kissed him again.

Chibi (yet slightly older) Kyuubi and Chibi (yet slightly older) Itachi were standing inside, and just happened to look out the window. Kyuubi was laughing his butt off while Itachi was trying to decide between laughing or breaking the boys up to tell them that it's inappropriate. When he saw Sasuke's bright, childish smile he settled for smirking in amusement.

"What did you tell him?" Itachi asked Kyuubi.

"I only said that it was okay to kiss people that you like." He looked at Itachi. "You should try it sometime."

Itachi looked away, hoping to hide the slight blush that was very visible on his pale skin. 'Does Kyuubi know?' Itachi wasn't sure what to do. What if he ruined their friendship?

Kyuubi rolled his eyes and mentally sighed. He'd known that Itachi liked him for a few weeks now. "'Tachi."

"Hm?"

When Itachi turned around, Kyuubi instantly kissed him. It was a light kiss, but it got the point across. The Uchiha's blush deepened as he relaxed.

"Wow. Did my brother just blush?" Sasuke asked Naruto in what was supposed to be a whisper.

"Yup."

The two older chibi's turned around to see the younger ones. If Itachi hadn't been an Uchiha, his blush would have deepened, but he managed to keep some of it down.

Kyuubi smirked. "I didn't know that Sasuke-kun was that close to you, Naru-chan."

Said blonde blushed slightly, but tried to cover it with fake anger. "You were watching us?! You said that you weren't supposed to stare at people who kissed!" If Naruto had known of the word 'pervert' at the time, that's what he would have called Kyuubi.

"You're not supposed to watch people. But you're my baby brother. That's different."

"How?"

"It's my job to know every embarrassing detail about you."
