"Where were you?" his sister demanded to know the second he walked through the door. She was absolutely furious, and even though she couldn't hurt him, the young Fire Lord still considered turning around and either asking for back up or just leaving the place and coming back some other day.

Zuko ignored his own anxiety and gave her a cynical smile "Did you miss me, my love?"

"Don't get your hopes up, Zuzu. I might be playing along to your gross fantasies, but I'm only doing it because I have no choice and because you were supposed to treat me better because of it"

"I am treating you better"

"You weren't even here, you asshole!" he could hear the pain and hopelessness in her voice. He had not visited her in almost a month after she continued to mistreat her doctors. It was probably the longest, harshest, most boring month of Zuko's life, but he had a plan. He knew very well that one of the reasons why she wasn't resisting his advances as much she would have otherwise, was because he was feeling completely alone. Zuko had gone through something similar when he was banished, and if he had not had his uncle by his side he would have probably ended up like his sister. He lost his home, his title, was seen as a disgrace both to his family and to his nation - and would have done anything just to hold onto the belief that he was still loved.

Luckly for Azula, he truly did love her, despite the horrible things he did to her. He had been obsessed with her for far too long to care about right and wrong anymore. Manipulating her and toying with her emotions was unbelievably cruel and any sane person would tell him that he was just as sick as his sister, if not more, but he was forced to make peace with his need to hurt her a long time ago. And in a weird way, this made him feel closer to her - he could finally understand why she constantly felt the need to be in control of everything and everyone, why she had always loved toying with him and treating him like her puppet. There was something addictive in the thrill of making someone as powerful as his sister submit to him.

"I'm here now" he cupped her cheek "If you had shown that you wanted me around, I would have kept visiting you."

"Liar" she said, slapping his hand away "I've done everything you wanted me to do, and you still turned your back on me."

"Come here" he pulled her close, kissing her passionately "You know very well that you were misbehaving, and that I could have done much worse to punish you for it. I'm giving you another chance because I know this is hard for you, but you have to learn to do what I say. And if you do it well, I might just be kind enough to give you a real reward."

Azula let him kiss her again and again, and shivered as he touched her everywhere. He had missed her warmth, her scent, her taste, her little gasps for air, the feeling of her soft skin against his... and the forceful, yet somehow still delicate way she kissed him back once she was no longer strong enough to keep pretending she didn't crave him, or at least the affection he'd give to her when he decided to be kind.

After a few instants, Zuko pulled away and forced his sister to turn around. He sucked on her neck while groping her breasts and rubbing his erection against her ass. He smirked as he heard her needy little whines. He removed her robe then took off his own clothes, making her face him again so he could give her another kiss before grabbing her legs and wrapping them around himself. His sister moaned as he slammed her against the wall and immediately forced his cock into her.

He gave it to her hard, fast and deep, making her back and head hit the wall over and over, and was pretty sure the entire hospital could hear her desperate screams as he violated her. He could taste her tears as he kissed her face, and she got a few from him with how deep her nails were digging into his back and shoulder. The sight of those scared, lonely, loving eyes was almost as tempting as the malicious smiles she couldn't fully hold back whenever he hit just the right spot or a groan of pain escaped past his lips.

Zuko could feel himself getting closer with thrust. His plan left him starved of her, and while he knew it would be a matter of time before he could have her whenever he wanted, it was still difficult to bear. Just fantasizing about Azula had never been enough, but it was even more unsatisfying now that he knew that being with her was even better than he could have ever dreamed of. He had not taken another lover - what was the point of being with anyone when all he would be thinking about would be his sister anyway?

He didn't wait for Azula to reach her climax before letting himself fall, and he could see the confusion and frustration all over her pretty face. He smirked and carried her to the bed, getting on top of her and grabbing her pale throat with both hands, choking her for just a few seconds, letting go, then doing it again. And again. And again. Over and over, adding a few more precious, torturous seconds each time, bringing more tears to his sister eyes, hearing her sobs, gasps, moans and pleas as he allowed her to get just enough air to stay conscious. She'd unsuccessfully try to break his grasp on her neck, hit him, and even try to bend despite knowing she was unable to.

"Behave" he commanded, but used a gentler tone "You know I don't want to actually hurt you. I'll make you enjoy it as well, Lala"

She stopped fighting and he rewarded her by using one of his hands to rub her clit, stimulating her just enough to leave her in a pleasurable hell as he continued to control her breath. Holding her pain, her pleasure, and her life at the palm of his hand was unbelievable and the fact that she had actually found it in her heart to trust him despite of what he was doing and had done to her made him feel even more love for her, which he had not thought was possible.

Zuko noticed his sister was close to orgasm and stopped his teasing, leaving her unsatisfied. He used both hands to grope her breasts, twisting her nipples, then kissing her stomach. He gave a long lick to her cunt, then just kissed and bit her thighs, never giving her what she wanted. He choked her again a few more times, just to hear those desperate cries, then started jerking off, coming all over her shocked face.

"Such a lovely look for you, Zula" he ran his thumb over her cheek and made her suck his cum, then wiped it off her face with her robe, which made her even more mad. Still, she did not yell at him, just gave him an angry look.

She's learning.

He licked one of her nipples, then gently nipped on it before sucking it, slowly getting more and more of her breast into his mouth. He then did the same to the other. His cock was already hard again, but still he refused to force it inside her, enjoying seeing her burn with lust. After she had calmed down just enough, he started fingering her, only to stop yet again as he denied her another orgasm, making her whine like a child.

He got away from her, smirking "What's wrong, Lala? What is it you want?" he asked, already expecting to be insulted or yelled at, but his sister seemed to be to far gone to put on an act.

"Please, Zuzu" she said in a weak voice as she crawled towards him "Please fuck me. Ravish me. Do whatever you want to me, but please just let me come. I need it so bad"

"Admit you like it" he said, wrapping his hand around her pale throat as he pulled her to his lap "Admit you like being my little whore. Admit you love my cock."

His sister rubbed up against his cock, desperate for any contact, making them both moan "I do. I fucking love it. I love everything you do to me" she kissed his neck and nipped at his ear, sucking the lobe into her mouth "And I want more."

He still refused to give her what she needed. She knew very well there was one more thing he wanted to hear her say, and right now he would not care if it was a lie.

And he got what he wanted.

"I'm yours, Zuzu"

Zuko grabbed her hips and brought her down on his cock, making her scream. He started chocking her again, only letting go as she reached her peak, seeing Azula's eyes rolling back and her mouth falling open. Her nails digging into him like the claws of an animal and making him bleed pushed him over the edge as well.

Azula kept bouncing up and down, taking him deep, clenching around him hard. The feeling of her continuing to hurt his back and shoulders made him thrust faster without even meaning to. He kissed her with more passion that he had ever kissed anyone, one hand around her neck, the other pulling her hair, his tongue toying with hers, sucking and biting her lower lip, swallowing her little gasps and groans, stealing her breath.

"I love you, Zula" he said, moving his kisses to her neck, grabbing her ass and circling her asshole with one of his fingers before inserting it into her, just to hear her little groan and feel her trembling. He loved how responsive she was to every little thing he did.

His sister continued riding him, moaning right in his ear and grabbing his hair, her nails gently scrapping his scalp. He could see that dangerous, dark spark burning in her golden eyes - the spark he had only seen during their Agni Kai, when she was completely lost inside her own mind, too broken to care if the whole world was burning around her. Even the way she touched him felt different now; for once she didn't seem to be holding back at all, simply accepting his twisted affection for her and returning it eagerly. Every time he teased her in any way, groping her or biting her neck, he could her a low, perverse chuckle escaping her lips and it made his blood boil with need.

Eventually Azula's moans turned into screams again, and Zuko could feel her contorting and pressing up against him, as if wanting to fuse their bodies together as she reached her second climax, her skin burning, her walls squeezing him again, and wet sounds coming from in between their legs as she squirted. Once Zuko spilled himself inside her for the last time, she got off of his lap, ler legs still shaking, which made him smirk.

He embraced her and gave her a sweet, tender kiss, and started playing with her hair. Azula offered him a kind, lazy smile, leaning in to his touch.

"You were a good girl today. I think you deserve a reward" he said, kissing her forehead "I'm taking you home tomorrow"

She jumped up, looking at him with wide, hopeful eyes "Really?"

"Of course. But you need to be on your best behavior, which means doing everything I say. Can you do that, Azula?"

"I can" she promised, taking his hand in hers and pressing a quick kiss to his lips "I'll be good. I'll be your perfect little sister, Zuzu. Just get me out of here. I can't stand this place anymore"

He smiled "I'll prepare everything for your arrival and come pick you up in the morning" he assured her as he hugged her again.

She was finally ready to be his.
