(REWRITTEN FROM ORIGINAL – mostly to fix some grammatical errors and weird writing formats)

This story is SMUT and for MATURE AUDIENCES! There will be sexual scenes and language. MATURE MATURE MATURE! Although the first two chapters are pretty smutless…but the later few chapters will be full of it…

Relationships are: Sokkla and Zutara (with little hints for others as well…read it to find out) This is purely a romance/smut story.

Third: Where are we at and what's going on: Azula joined the Gaang shortly after the failed invasion of Black Sun, she brought along Ty Lee and Mai. Zuko and Aang did go to the sun warriors and Katara and Zuko did take the journey to find the captain of the southern raiders. But Zuko and Sokka never took the trip to Boiling Rock. They moved to Ember Island not because they were discovered at the Western Air temple, but because they needed to get closer to the battle fields of the war.

(Again this is a Sokkla and Zutara story…NO INSEST because that's just…ick!)

LASTLY (And most importantly) I DO NOT OWN AVATAR THE LAST AIRBENDER or any of the characters. I create this story only because someone created the characters for me. I will now nor ever make a profit from this story.

Ooookay now that we've gotten through that…let the story begin!:

Chapter 1: Desires Understood

Zuko couldn't believe it, couldn't understand it, and was getting really fucking annoyed by it. He was hard as hell and had been for almost two full days. The reason, he had no clue.

No one was around as he walked off his frustration on the beaches of Ember Island while the sun began to set. Nothing was on the beach to be causing such a reaction, yet he couldn't seem to get rid of his raging erection.

It couldn't just be raging hormones, he'd learn to control those years ago. So why was he so fucking hard?

"Having fun Zu-Zu?" a sarcastic voice that could only be his sister, came from behind him. Turning he found Azula, dressed in a casual red mid drift halter top and a long red skirt, hands on her hips smirking at him. Zuko casually held his claps hands in front of his erection, hiding it from her view.

Azula, along with Mai and Ty Lee, had joined the Gaang after the failed invasion of Black Sun. She claimed she was tired of dealing with Ozai and his over egotistical ways and had no more desire to rule the world through the fire nation, but Zuko knew there had to be more to it. Even when they were little, Azula always wanted their father's approval and to dominate the world. It was the only two things she had ever wanted.

This change of heart was taken very cautiously with the Gaang. Their reasons for even trusting her at all was only because she had shown up at the western air temples with Sokka and Katara's father Hakoda, and Sokka's girlfriend Suki. Mai and Ty Lee had vouched for her change of heart as well. Zuko was willing to believe Mai, even though she was pretty pissed at him because of the break up, but Ty Lee…he wasn't sure about.

They had all met up at the western air temple, but as it was getting closer to the arrival of Sozin's comet, the Gaang had decided it was time to move back to the fire nation. Everyone had moved to Ember Island and now they were training and living in the mansion of the fire lord, hidden, practically in plain sight.

"Go away Azula, I don't want to deal with you right now," Zuko cursed. The last thing he needed was his sister seeing him in this state…it was…demoralizing.

"You've been pacing the island for the past hour. I'm simply wondering what could possibly be wrong? Are you worried about the comet? Or perhaps about facing our father? Or maybe it's something more….personal?" When she quirked her eyebrow up and smirked, Zuko got the feeling she knew what was going on.

He glared at her, "I'm not worried about anything. Go away." He turned and started walking again, noticing that his erection, for the first time in two days, had gone flaccid.

Maybe she does have her uses...

"What if I don't want to go away? Are you going to make me Zu-Zu?" As she walked next to him, Zuko was both annoyed and thankful, the more she talked, the less frustrated he seemed to become.

Good, this is good. Now I can go eat and sleep tonight.

Changing direction, he started walking back to the mansion.

"I wouldn't go back there yet, not unless you want to be…uncomfortable again."

Her arrogant attitude was really getting on his nerves. He stopped mid stride on his way back to the mansion Wait a minute…

He turned and faced her directly. She was smirking. As he looked closely at her, he noticed her shaking slightly, as though cold.

It's too warm for her to be cold out here…

"Do you know what's going on? Are you having…issues?" While he really didn't want to know about his sisters…intimate issues…he would like to know what the heck was going on, and his best source seemed to be her.

"And what kind of issues would that be brother?" That smirk was still there, which only fueled his irritation. Under no circumstances was he going to detail out his…issue or ask for details about hers. If she didn't know what he was asking, he wasn't going to elaborate.

"Never mind, I don't want to know. And honestly, I don't think you know anyway," he turned back and continued towards the mansion. After two more strides, he felt his sister grab his arm, stopping him once more.

"It's the comet," her voice was quite yet stern. "The comet…it causes fire benders to feel more than just an increase in bending power."

Zuko turned back to Azula, for the first time ever he saw her nervousness.

"What do you mean?"

"I overheard father talking. There's a legend surrounding the comet that not only does it increase the bending abilities of a fire bender, but it increases their…well…" she looked around nervously. They were still pretty far from the mansion, no one would be coming out to look for them…yet.

Azula…nervous? What the heck does the comet do?

"What? Increases there what?" But Zuko already had a suspicion…he had been hard for hours…

"Well if I have to spell it out…their sexual appetite," she whispered the last words.

Oh for the love of the spirits.

"I don't think it's just a legend…"

"Me either," Zuko replied.

Azula watched Zuko's face moved from annoyance to shock after her announcement. She didn't want to go about telling him this way, but any other way of telling him had just seemed…weird. If she hadn't had overheard her father talking about it with the general, she wasn't sure how she would have been told either.

Best way to get any information out there, was bluntly, in her opinion. No point in beating around the bush and being all shy about it. Sex was a good thing, discussing sex with her older brother… just weird. Better to get it out fast and move on with how to fix it. Not to mention, they'd never had a close brother sister relationship.

For once, she was glad her brother was around. Being near him was helping her control the increases in her desires just like she knew she was helping him. Besides the women, he was he only person in the house that did nothing for her, for obvious reasons.

"So…this…issue," Zuko said, "is because of the comet?"

"Well, that and you obviously are attracted to someone in the group. The closer you are to that person, the more the desire will grow," Azula said pointedly. Watching his face closely she asked, "Is it Mai?"

"No," Zuko responded. Azula grinned at his softly spoken curse.

Oh oh…now we're getting somewhere.

"If it's not Mai than who is it?"

"It doesn't matter. Now that I know what the hell's going on I'll be avoiding them anyway."

"Oh come on, you have to tell me now. If it's not your ex who possibly could it be Zu-Zu," Azula ran through the women in the group.

Toph…too young. Ty Lee…to annoying. Mai he already rejected. Suki…well could be her but she's with Sokka and Zuko's not one to move in on another man's woman…

"The water bending Bitch? That's who you have the hots for?!"Azula almost shouted.

"Will you shush…,"Zuko grabbed her arms and pushed her further away for them mansion.

Well well…that worked out well...

"It IS her! Oh my Agni Zuko! Of all the women, SHE'S the one you're attracted to? WHY? She's a..a…a freaking peasant!"

Not to mention a pain in the ass. Katara hated Azula, Azula hated Katara. It was a relationship where they both knew where each other stood.

"What does that have anything to do with anything? She's…" Azula cocked her eyebrow as Zuko's facial expression changed from annoyed to…enchanted?

"A bitch? A mother wannabe? Controlling? Pain in the.."

"Strong, caring, forgiving, gentle…"Azula couldn't help the unladylike snort she made.

"Okay, well what about you then? Who do you have the…hots for? I can't believe I just asked that…" Zuko covered his face with his hands while turning in a circle.

"Who says I have the hots for anyone? They're all peasants here after all," Azula replied arrogantly. There was no way she was telling him anything about it. She only discovered it herself and was still pretty repulsed by it…he was a savage and a peasant. Not acceptable.

"You stopped me from going to the mansion, because you know how to keep it under control. You'd only know how to control it because you're feeling it to and you're feeling it because you have the hots for someone yourself. All that I can't figure out is why you've told me or why you're helping me," Zuko said through his hands.

Well…maybe he's not as stupid as I thought…

Azula watched as Zuko removed his hands from his face and took a deep breath.

"The Duke?"

"Eww, too young."

"Teo?"

"Too inexperienced"

"You have no…nope I do not want to know."

Azula watched him, she could see the wheels moving in his head.

It's not going to work brother…don't even try it. But she was enjoying him squirming over the discussion, which was the only reason she continued it.

"Haru?"

"He'd never keep up with me." Azula grinned as Zuko shuddered in disgust.

"We are not going there…at all…"

"See I told you I don't have the hots for anyone. I just have a theory and because I'm so…"

"Sokka?"

Azula paused but quickly caught herself, as carelessly as she could she responded, "Please like I'd have any interest in that Peasant."

Zuko moved closer to her, a smirk of his own on his face.

Since when does he smirk…or smile…ever…

"That's it, isn't it? Sokka. Arrogant, prideful Azula Princess of the Fire Nation, is attracted to the Southern Water Tribesman. Wow…this is…interesting."

Azula glared at him, damn it…damn this comet!

"I'm not going to give you the satisfaction of an answer for that ridiculous question. I am NOT attracted to this smelly, over confident, meat eating, half-ass swordsman." Azula crossed her arms, finding it difficult to keep the annoyance from her voice.

"You're insulting him, you like him."

"Oh please I insult everyone."

"You overly insulted Sokka. Which, in your weird Azula way, means that you like him."

Shit…when did he get to be so…smart?

"Whatever. The point of this all, is that we know what's going on and we know what our…your… weaknesses are, so that you can control it better."

"Right…because I'm the only one with weaknesses in this…" Azula didn't miss the dry sarcasm in his voice.

"Come on, let's go back to the house. The suns set and I'm sure they'll be looking for us soon." She grabbed his arm, leading him to the house.

"Wait," he pulled her back. "Should we tell them?"

Azula was appalled.

"What?! Why?! Not to mention how would we do that?"

Mockingly, and probably a little louder than she needed to, she said, "Oh hey everyone, just so you know Zuko and I are going to be acting a little weird for the next few days due to the comet. It turns out the comet has an effect on Fire Benders sexual urges and increases them exponentially. So if you see one of us just walking away from the other sex, just let us go because it may be because we want to fuck them. "

Going back to her normal arrogant tone, she continued, "That'll go over real well I'm sure."

"Well I don't think I'd say it like that…but it would be interesting to see Sugar Queen's face if you did."

Azula and Zuko turned, stunned to find Toph standing there, a huge knowing grin on her face.

"How…how long have you been there Toph?" Zuko asked quietly.

"Just long enough to hear Crazy Queen's little speech. That why you've been acting so weird, Sparky? Who you got the hots for? Hope it's not me…that'd be…weird."

"No, Toph I don't think of you that way. I don't think of anyone in the house that way," Azula caught his pointed look, and decided to stay quiet. If she didn't talk, he wouldn't talk. Since she could barely keep him from believing her denial, odds were she wouldn't be able to make the others believe her as well.

How did I get so bad at this? I used to lie like it was my second language. Damn comet… she wasn't really sure if it was the comet, but for now, she was going to blame it.

"And we need to keep this between the three of us okay? We don't need the whole house freaking out over this. Azula and I have it under control, okay?" Zuko continued.

Azula could see the earth bender consider his request. Overall, Azula did like Toph, even if she insisted on giving everyone ridiculous nicknames. The bender was smart, tough and had an I don't give a shit attitude that Azula could respect.

"Under control? Sounds like you two won't have it under control until after the comet…but since I'm such a nice person, I'll stay quiet."

Azula and Zuko let out the breath neither of them realized they were holding.

"BUT I do think you should tell everyone. Just because you two have it under control, doesn't mean the other fire benders in the city will. Everyone should be warned so they aren't caught unaware in town."

Didn't think about that…

Looking at each other, Azula and Zuko said in unison, "Shit…"

Ending author note: Hey… the second chapter is posted as well! Woot Woot!
