What My Brother Doesn't Know

Another chapter I've whipped up quickly from the back of my brain. Hopefully it doesn't stink because it was written so quick. I know some of you will either be annoyed with me or laugh at the ending.

R&R

"Why did we have to come?" Aang muttered to himself, unknowingly a certain waterbender heard him say this.

Katara softly elbowed him in the side making him look at her, "It would've been rude if we hadn't."

It was Zuko's 19th birthday and against his will, a party was planned for the young Fire Lord and, of course, the Gaang along with old friends from the other nations and some never seen before arrived at the party. At the moment everyone was seated at dinner. Zuko was at the head of a large table with Aang to his right and Sokka to his left. Katara was seated next to Aang and Toph next to Sokka. Of course there wasn't enough room at the table to seat everyone the sages had invited. There were four tables and it just so happened to be the one perched slightly higher than the others they were seated at.

Aang rolled his eyes. "I specifically remember Zuko saying he didn't want a big fancy birthday party." He stuffed a grape into his mouth and shot the guards a grateful look. There were guards stationed at the steps to the high table and at the moment they were stopping another group of fan-girls and boys seeking a dance with the hero's.

Katara sighed and took another scoop of lettuce from the bowl set in front of her and Aang. "I remember hearing that too." She suddenly blushed as she thought of why this memory stuck out so clearly in her head.

Flashback to 2 months ago

A letter had just arrived at the temporary home of the Gaang in Ba Sing Se. None were too excited to open it seeing as how every letter they got were one of the three.

1: From Admirers or so to speak, fans.

2: From nobles seeking pointless meetings with the Avatar and the Fire Lord.

3: Another request from the Earth King or someone to come to solve problems around the world and bring peace.

This letter didn't seem any more important. Currently it sat in the middle of the kitchen table while everyone else was off doing whatever. Katara and Mai were playing Pai Sho while Suki and Sokka had disappeared somewhere. Toph had excused herself when they had gone and hadn't returned yet. Katara was bored and sad because she hadn't been seeing much of Aang lately. Mai was no different. Their boys were always off in some important meeting or just disappearing for awhile and coming back exhausted for some odd reason.

Just as Katara was about to win the game the door opened and the boys entered the house and each collapsed onto a couch. Zuko on his back and Aang on his stomach. Katara and Mai shared a look before smirking and sneaking up on their boyfriends. They had become close friends and knew everything about each other...even their love life.

Katara and Mai stripped the boys of their shirts and loosened the drawstrings on their pants. They shared an evil smile before stripping themselves to their underclothes. Katara slid underneath Aang and Mai layed on top of Zuko. They situated each of the guys hands so they were resting on their exposed skin and mentally counted down 3...2...1...

"Oh ZUKO!" Katara moaned loudly into Aang's ear while scraping her nails down his back.

At the same time Mai cried into Zuko's ear. "AANG!"

Both boys jerked awake. Aang scrambled off of Katara while Zuko squirmed out from underneath Mai, both thinking they were with the wrong girl. Katara and Mai burst out laughing at their faces and even more so when their movements made their pants fall to their ankles. Still half alseep Aang and Zuko grabbed their pants, hiked them up to their hips and tried to run out of the room, smashing into each other.

That had certainly woke them up. They shared a look then turned to the girls that were both half-naked, and rolling on the floor, clutching their sides and laughing their heads off. They glared at the girls before sharing an evil smirk of their own. Aang ran over to Katara, scooped her up in his arms and took off upstairs before anyone could say anything.

Zuko was about to do the same until Mai pointed out the letter that had come. Zuko grumbled and went into the kitchen while Mai re-dressed. Upon opening the letter his eyes widened and he suddenly acted like a small child. "I DON'T WANNA FANCY BIRTHDAY PARTY!!" He cried and buried his head into Mai's chest, smiling as he did so.

That's how Katara and Aang found out this little fact, though Aang was busy getting payback from the mean joke played on him.

Flashback End

Katara rubbed her wrists, remembering earthen cuffs that were crafted around them. Aang took her hands in his and smirked, knowing what she was thinking. Katara's blush spread to her ears and she quickly took her hands out of his, returning to her salad.

Aang's smirk widened when he saw a glass bowl filled with ripe cherries. He took a handful and dropped them into Katara's little fruit bowl. She looked up at him and watched as he bit into one and pulled the stem off before dropping it in his hand. He did the same with another and another until he had five cherry stems in his hand. Katara was still watching him.

"Want to play a game?" Aang raised an eyebrow at the blushing waterbender before him.

"Okay." Katara whispered shyly, soooo unlike her.

Aang's smirk turned into a toothy grin, "Open your mouth and stick out your tongue." She blushed but did as she was told. Aang dropped a cherry stem onto her tongue before placing one on his own.

"Whoever ties the stem in a knot first wins." Aang closed his mouth around the stem and so did Katara. He held up three fingers, two, one. Go! They stared at each other, seemingly playing a staring contest but unseen their tongues worked on the stems that were almost impossible to tie except for those were...gifted.

Aang stuck his tongue out with the stem in a knot while Katara was still trying to force the stem to go in the direction she wanted it to go.

"I 'in!" He stated and spat the knotted stem onto his plate. Katara spat hers out too. "Guess that means I'm the better kisser." He grinned, clearly meaning more.

Sokka had watched the exchange between them and was shocked when Aang had tied a cherry stem. "Holy! Aang how the hell did you do that?" Sokka hissed over to him. "I can never get the stem to bend with my tongue! Where'd you learn how to do that?"

Aang chanced a glance and grinned in satisfaction, Katara was red once again.

"Practice. Lots of practice."
