A/N: I promised this a while ago!! And I feel really bad for putting it off!! BUT! Now that Designing Love is over (go check it out), I'm gonna bust out this last chapter and maybe make an epilogue! I'm not sure though if I want to drag this story out. I mean, technically it was just supposed to be a great one-shot, but no, I had to go extend it! Haha! I did actually have 3 pages of this written out, but decided to start over! Don't ask! Just enjoy!!

Warnings: LEMON!! Of course!!

"Why don't you just stay with us, Katara?" Aang asked hopefully. He knew what kind of state she'd be in. The thought almost disgusted her.

"No Aang," she didn't even bother giving an explanation. Just…no! His face fell and he looked disappointed. But she wasn't going to have the thought of raping a fifteen year old boy on her hands though. She herself was only seventeen, and hadn't told the boys about last year. When she'd lost her virginity to Zuko, Prince and traitor to the Fire Nation, she hadn't told her brother and the Avatar. Although, they didn't really want details about her night anyway, so it had been easy for her to lie. She hadn't forgotten though. The funny thing about the eclipse is that you aren't in control of your body at all. But your mind will remember. Not at first, but the night will flash before your eyes during the next day. She saw what had happened, and hadn't been able to forget it.

The memories haunted her. Is haunted the right word? Making love isn't something to be ashamed of. But giving yourself to your sworn enemy for a night of pleasure because the sun and moon decide to become one? That didn't mean she had to become one with Zuko! But she had. That was the haunting part. She had been so weak to defend herself. She remembered hitting him with a water whip, but it had drained her energy. Ugh. It bothered her so much!

"Katara?" her brother interrupted her thoughts.

"Yes Sokka?" she put on a cheery face.

"Are you okay?" he was concerned.

"Yes. I'm fine. I'm just worried about the lunar eclipse tonight. I can't stay here with you guys, but where am I to go? We're in Ba Sing Sei! There's no where for me to hide! And I don't want to waste any more money on a hotel!"

"Maybe you can leave the city tonight. We can pitch you a tent on the other side of the wall. Appa will fly you over and back! How does that sound?"

"I guess that will have to do. I really hate this eclipse Sokka. I really do."

"I know…I've had to live with you when it first started affecting you. How old were you? Thirteen?" she nodded. "Yeah! Luckily for me, I'm not a bender!" he joked. He always felt left out because he wasn't a bender. But this one thing he had, that she lacked! Self-control on the eclipse nights.

"Well, we might as well go now, before I feel too weak," she shrugged. Sokka only nodded and they began to load Appa up with what she would need.

"ZUKO!!" Iroh happily exclaimed! "We have finally made it to the city of Ba Sing Sei!"

"Yea…great," he said unenthusiastically.

"But before we enter, we must camp around the outer walls. For tonight is the-,"

"The eclipse, yeah, I know uncle. I'm walking further away than you because I am younger."

"Aw! How nice you are to your old uncle!" Iroh touched Zuko's longer hair. Zuko scoffed and headed around the walls of Ba Sing Sei. He couldn't risk being in such a populated area tonight. The wall would, thank Agni; shield him from any potential sexual acts. And that's when he got a flashback.

Zuko's Flashback

He wrapped his arms around her back and lifted her up, never taking his mouth off of hers. He walked over to the dresser and with his hand swept the contents on the floor. He needed her. She ripped at his tunic, and he pulled his arms through letting it fall to the floor. He pushed the robe past her shoulders, lowering his mouth to her right shoulder, biting hard. She lifted her hands up, and removed the cotton material. He pushed her against the mirror, sliding his leg in between hers. Pressing his thigh against her she fumbled with his pants. He grabbed the thin fabric, and ripped her panties from her body. She finally unbuckled his pants, and let them fall to the floor. He pulled her closer and lifted her knee upwards, allowing him all the access in the world. "Do it now," she hissed in a voice unlike her own. She wrapped her other leg around his waist and he forced himself inside her. She let out a scream at the sensation. He groaned inaudible words, and drove himself into her, making them lose their minds

End Zuko's Flashback

The next morning hadn't faired well. They both regretted what they did, though Zuko had to admit, the flashbacks he kept getting were nice. She had been a virgin, and in his dreams he had actually felt his member throbbing inside her. And she was tight. The only good thing about eclipse sex, even though you don't feel it that night. Following nights are just as good. You feel the sensations, and it's almost like you're having sex all over again. But it wasn't just the sex he enjoyed. He had to admit, he liked having sex with Katara. He had plenty of concubines when he was younger, and the flashback sex hadn't been that great. Although, he had been thirteen, and chained down to a bed so he couldn't escape. This past time, he had been in "control."

He looked at the moon, coming close to the sun. He'd have to pitch a tent soon. But he wasn't far enough from the gates yet. It wasn't too hot outside, or too cold. The presence of both sun and moon balanced out the day. But once they joined, he would weak. Not only because he'd be a sex-starved fiend, but because it was a lunar eclipse. He thought back to the solar eclipse, with Katara. How he'd taken control of her; propping her up on the dresser, to then dominating her in the bed. It would be a complete one-eighty this time around. That is, if was with her or any other waterbender. But there weren't other waterbenders on his mind. All he could think about now, was Katara. And he shouldn't be, he knew that. But for some reason, she was in the back of his mind.

Katara was almost all set up. Her brother left on Appa back on the other side of the wall. Now she was just trying to make her tent more comfortable for the night. She was sewing the opening closed to she wouldn't leave. It was hard work, but she should be finished by the time the sun and moon became one again. Suddenly, she pricked her finger.

"OUCH!" she dropped the needle and thread and sucked on her pointer finger. It was a small pin-prick, but it stung. She heard her voice echo in the vastness she was currently in. She looked around and saw nothing. It was nothing really but desert and open sky. The city of Ba Sing Sei was completely different than what was on the other side of the wall. Where she was. She sucked on her finger a little bit more, before hastily wiping it on her blue dress, leaving a smear of red. "Great," she threw her arms up in frustration. Returning back to her needle and thread, she continued sewing the tent shut.

Zuko stumbled to keep walking. The eclipse was affecting him already, and he was finding it difficult to keep walking. He didn't know how far around the wall he was. He should probably stop soon, but for some reason kept going. Something was calling him. He had heard a yell echo moments earlier, and it was female. His mind wanted him to stop, but his nether regions encouraged him to keep walking, just in case that female was near by. And all his for the taking. He clutched his chest tightly, as he saw something in the distance. Something blue.

Water tribe? He knew somewhere in the back of his mind that the Avatar was coming to Ba Sing Sei. And with the Avatar, came Katara. As he closed the distance between himself and the object, he soon saw that it was a tent, and indeed it had the water tribe insignia on it. It was the eclipse. And there was only one person who could be in there. His shaky legs somehow grew strength upon knowing Katara was in there, coming close to losing her mind the eclipse. He knew she would want him sexually, and his stumbling turned to walking. His walking eventually turned to a jog; which then transformed into a sprint. When he finally approached the tent, he gulped. The entrance had been sewed shut. He glanced quickly at the sun, which was about to be taken over by the moon. They were about to become one. And in the back of his mind, he longed to become one with Katara.

Reaching to his side, he withdrew a small knife. Holding it firmly, he started at the bottom and cut away her sewed efforts half way. Then he crawled inside the tent with her. When he looked at her, her face was startled and nervous. In her hand, she clutched an ice dagger, ready to stab the intruder. Until she saw it was Zuko.

"Katara," he rasped her name. She looked utterly shocked.

"Zuko? What the hell are you doing here?"

"The…eclipse…" it was becoming hard to talk. The sun, and he were weakening. The moon was taking over.

"I know, but…ugh…what are you doing here?"

"Uncle and I…we came to Ba Sing Sei…but…apparently had the same idea you did…"

"Be on the other side of the wall to avoid the people in the city," she finished his sentence. She sighed in frustration. It was bad enough they had sex the last time. Apparently he had come here for more. Not this time.

"Get out of my tent!" she ordered. He gave her a confused look.

"What?" he panted.

"Go!" she pushed him, and he fell on his side. His face had broken out in a sweat. It was the first time she noticed he wasn't well looking. "Are you okay?" her head began to throb, but she tried to push it away.

"The moon…" he whispered. "It's weakening me…taking, over…I need…sex," he gripped her hip, but not as firmly as she knew he could have. He looked like he was about to pass out. A sudden tremor raked through her body which had her screaming. The moon was controlling her. Zuko's black eyes glared at Katara. The last time they had been 'together' her eyes were black, like his now. However, her eyes were white, and seemed to give off a faint blue glow. Like the moon itself. It turned him on even more, and suddenly his mind was lost.

Katara didn't feel her mind slipping like she had the last time. It just consumed her in an instant. The small headache she had earlier was nothing like last time. And the process of being of sound mind was shorter this time, whereas last time she struggled to get away and fight Zuko. Her white eyes looked into his black ones. She wanted him. He was still weaker than her, and there he lay, in her tent. Hers for the taking. Without hesitation, she pressed her lips against his. His tongue immediately plunged inside her mouth, tasting her. He was aware of her ripping open his tunic, and scratching his bare torso down to his pants. As she worked on untying his pants, he disposed of her dress.

In not a lot of time, the two teens found themselves completely nude, and extremely ready for what the eclipse begged of them. Zuko, too weak, was lying on his back, while Katara straddled him. She placed more kisses along his jaw, and he felt her rubbing her core against him, but not penetrating. He hissed as he felt her hand gently massage him. Zuko grunted as Katara lowered herself to his member and licked away the pre cum. She smiled seductively, and returned to the passionate kiss she had broken off earlier. He could taste himself in her mouth, and he felt his member rise even more the occasion. Katara slowly positioned him at her entrance, all the while kissing Zuko. With a swift movement, she pushed her hips down, filling herself to the hilt.

Zuko broke the kiss, and groaned at the sensation. She sat up from his chest, and rocked her hips slowly. His hands traveled up her thighs to her hips, guiding her against him. It was too slow. His fingers dug into her sensitive skin and he jerked her roughly. Katara threw her head back, and moan escaping her lips. Zuko kept one hand on her hip, the other traveled to her plump breast, where he began kneading it in between his fingers. Suddenly drawing strength, he sat up and captured her lips in another heated kiss. He thrust into her; hitting her in the spot she needed him. The kiss broke again, to allow for Katara's scream. Too weak, Katara fell back and let Zuko cover her body with his.

He continued to thrust into her, each push harder and faster than the last. He felt his release coming up quickly. He pushed her head to the side and roughly bit the juncture of her shoulder and neck. She came instantly. Hearing his name upon her lips, he too felt his release surge through her. He shouted her name, before shuddering and collapsing on the water bender.

Sokka woke up the next morning and quickly boarded Appa. "Yip, yip," he commanded the big beast. He had to go pick up Katara after her night. Flying high, it didn't take long for him to spot the blue tent against the beige desert ground. He tugged on the reins, and Appa quickly descended. Sokka gave him a rare and affectionate pat when the landed, before approaching the tent. "Katara?" he called.

Katara awoke at the sound of her name being called. Her head hurt. A lot. Her vision was blurry, and she made out the blue of her tent. Ah. The eclipse. She slowly sat up, her blue dress damp from sweat. She stuck her head out of the tent and looked into the blue eyes of her brother. She nodded absentmindedly at him, and they cleaned up her tent and other supplies. They boarded Appa and flew up in the air. 'What happened last night?' Katara's head still hurt, but she couldn't remember any of it. Then, a vision flashed before her eyes.

Katara's vision:

Katara slowly positioned him at her entrance, all the while kissing Zuko. With a swift movement, she pushed her hips down, filling herself to the hilt. Zuko broke the kiss, and groaned at the sensation. She sat up from his chest, and rocked her hips slowly. His hands traveled up her thighs to her hips, guiding her against him. It was too slow. His fingers dug into her sensitive skin and he jerked her roughly. Katara threw her head back, and moan escaping her lips.

"Oh, gods," she murmured.

"What was that Katara?" her brother was sitting on Appa's head while she sat on the saddle.

"Nothing Sokka, it was just a rough night."

"No details please, thanks," he and Appa changed direction to downward.

"I can't believe it…not again," Katara buried her head in her hands, but no tears came. They wouldn't.

SLSLSLSLSLSLSLSLSLSLSLSL

Zuko didn't feel bad that he left Katara in the tent. He figured her brother would be coming for her, and couldn't make her feel any worse than she probably would later. His flashbacks came quickly. Why wouldn't they? He woke up still naked, and collapsed on the equally naked water peasant. He dressed her though, for modesty's sake. He saw his uncle in the distance.

"ZUKO!" he said a little too loudly.

"Lee," Zuko corrected him.

"Ah, yes. My old mind has already forgotten. How was your night Lee?" he smiled at his nephew, who took some time to answer.

"Better than the last," he hugged his uncle briefly before entering the city of Ba Sing Sei.

A/N: Now technically, I left myself open for a continuance, if I so wished. Right now, I think not. However, there is a slight, and I mean slight chance. However, I really would just like to leave it off here. And if you're a moron and don't see how I could continue this let me give you a hint : They're both in Ba Sing Sei. And they had sex! DUH!

Anywhoozle, I'm glad this story is done with, and I thank all the fans of this story! It's been a long road, but I've loved every minute of it. Most of the time. REVIEW!! And go check out my other stories. They're AWESOME!!
