The first thing he saw as he opened the door to Azula's room, was her bed and the restraints that the doctors would sometimes use to keep patients bound to their beds. He walked in and spotted his sister on the corner, wearing a straight-jacket and in a wheelchair.
"What are you doing here, Zuzu?" she asked the second she layed eyes on him, feigning annoyance, but the amusement still clear in her voice.
Zuko sighed, closing the door behind him "Visiting my sister. And hearing the doctors complain about you yet again."
Azula smirked. It was all just a game for her. He had spent six months trying to find doctors who could handle his sister and make her comply with the treatment, but Azula always seemed to know how to make everyone so miserable that they practically begged Zuko to send her to another hospital. She had lost the crown when he won the war, but she still had power over others. Over him.
He was tired of that.
"At least you didn't burn anyone this time"
"I would have, if I were able to" she complained "The food in the other hospitals was atrocious, but at least it didn't taste like this gross medicine they put in everything here. Forcing it down my throat would have been better."
Don't tempt me.
"Any other complaints, your highness?" he mocked.
"Actually yes. The straight jacket is bad enough, but this?" she moved her head to indicate the restraints on the bed "It's downright cruel. I heard that patients often get seriously hurt because of it."
"The other hospitals didn't do that. Maybe you shouldn't have gotten yourself kicked out of them."
"You think keeping me in this horrible place is going to teach me a lesson, don't you?" she asked in that dangerous tone she often used "These doctors are weak. They'll crack soon"
"Maybe you're right" he said, walking up to her and making her raise an eyebrow "Maybe taking you from place to place is pointless and there is no doctor who knows how to handle you."
"You do have a brain inside that thick skull. I always wondered."
"If that is the case, then I'll have to deal with you myself" he said, circling her.
"You?" Azula scoffed "You wouldn't last a day. You don't know how to make me comply, you never did."
"I've changed, little sister" he said, squatting to look her in the eye and playing with her hair, his actions intriguing her "I know just how to handle you now."
"Do you, Zuzu? Do you really?" her low, sultry voice sounded like the sweetest music in the world to his ears, and it made his blood boil with need.
He brought his hand to the back of her nape "See for yourself"
Azula jumped up as he brought his lips to hers, kissing her passionately and demanding response. Still, she resisted as best as she could. When he pulled away, he saw that angry, yet terrified look in her golden eyes.
"What are you... what are you doing, you pig?" she screamed.
"Teaching you a lesson you'll never forget" he grabbed her arms and forced her to stand up "I know how fix you now, you spoiled brat" he crushed his lips against hers, biting and sucking at the lower one, before forcing his tongue into her mouth. Zuko groaned in pain and broke the kiss when Azula bit his tongue, drawing blood. He was angry, but it only seemed to fuel his lust for her.
He continued holding her close to him, his lips, tongue and teeth exploring her neck as she failed to break free. She tried kicking him, but her legs were still weak.
Zuko easily picked her up and forced her onto the bed, quickly grabbing a hold of the restraint in middle of it, keeping her torso bound to the bed. He then bound her ankles, but keeping her legs spread. He smirked, absolutely loving the sight in front of him. The brave, fierce, powerful Azula forced to submit to him and only him. He had waited for that for so long.
"Zuzu... don't..." she begged, shaking as he climbed onto the bed and on top of her.
He chuckled and pressed his hand against her cunt, making her gasp.
"I love it when you call me that. Don't move or this will hurt" her eyes widened and she froze in fear as burned her panties and touched her again, smiling maliciously "You're so wet" he said, watching her squirm as his expert fingers traced her labia and teased her clit "If I didn't know any better I'd think you like this, dear sister."
Azula looked at him with pure hatred in her eyes, the sight both arousing beyond belief and terrifying enough that anyone else would have cowered before her and leave her be "And people call me the sick one."
He inserted two fingers inside of her, making her scream in both pleasure and shock. He went as deep as possible and hooked them inside of her, his sister screaming and trembling like a scared child.
"Stop! Zuko, stop!" she had tears in her eyes and seemed to be struggling to breathe.
"So tight" he said, continuing to tease and explore her clenching hole "You're not a virgin, are you?"
She didn't dare to look at him. He smirked and started fingering her faster at the sweet realization.
"So nobody has ever touched you like this before. No wonder you're scared" he said, kissing her cheeks, the delicious taste of her tears exploding in his mouth "Don't worry, Lala. I'll take good care of you" he pressed his lips to hers, swallowing her cries as he used his thumb to stimulate her clit. This time, Azula didn't resist as much and after a few instants her lips parted and Zuko's tongue toyed with her's, exploring her mouth. He could almost immediately tell she had never been given a real kiss, but of course she understood what to do quickly - Azula had always been a fast learner.
Zuko broke the kiss and his cock twitched as he saw her gasping for air. He sucked on her lower lip and slowed down his movements a bit, watching her desperate sobs slowly turning into little moans of pleasure.
"I know nobody else ever touched you, but did you ever touch yourself?" he asked, but she didn't give him an answer. It looked like she just wanted to get this over it, and perhaps, some other time, he would have allowed her that courtesy.
But now he wanted everything he could get from her. Lust, rage, disgust, shame... anything.
"Come on, Zula. Tell me. It's just us" he added a third finger and started hooking them again "Did you ever spread your legs and masturbate? Do you still play with your tight pussy when the doctors don't force you to wear a straight-jacket?" she continued to ignore him, but he knew just what to say to make her react "Have you ever done it thinking about me?"
She growled and tried to attack him, but obviously failed. Still, her rage was enough to scare him for a second. He stopped fingering her and slapped her little clit, making her yell in surprise.
"You're strong, Azula. I always loved that about you. But it won't help you now" He grabbed her straight-jacket, burning and tearing it, doing the same to the simple hospital clothes she wore underneath, exposing her perfect breasts. She managed to free one of her arms, but he caught it before she could strike him and wasted no time to tie it up above her head. He freed her other arm himself, giving it the same treatment immediately, then tightening the restraint of her torso. He then groped and massaged her tits, teased and twisted her hard nipples before licking and sucking one of them.
Slowly he worked more and more of her breast into his mouth, sucking, licking and biting it repeatedly, then doing the same to the other. Azula trembled and moaned helplessly underneath him. He tore more of her straight-jacket, this time exposing her stomach so he could kiss it repeatedly as he patiently made his way to be in between her legs. He massaged and kissed them before cruelly biting them, making her scream, letting her tears flow again.
Finally, he pressed his mouth against her soaked cunt, moaning against it. His sister was extremely sensitive, and every little flic of his tongue made her gasp, moan, tremble and squirm. He inserted it into her hole, licking her, wanting to drink every single drop she had to offer. When he nipped at her clit, she lost all control.
"Oh, Zuzu... Zuzu..." she cried out, moving her hips to rub her cunt against his face. He grinned and sucked her clit into his mouth, making her scream his nickname as he ate her out like he should have done a long time ago, her whole body convulsing as he brought her to orgasm. She stopped moving at all, completely spent. Zuko took off his clothes and positioned himself in between her legs.
"No..." she said, her voice a mere whisper, as he pressed the head of his cock against her tight entrance.
"I made you come. Now it's your turn"
Without another word, he covered her mouth with his hand and plunged into her, his thick, large cock violating her tight little pussy as she screamed and cried. The sound of her muffled screams against his hand and the feeling of her walls squeezing his member were driving him insane, but he held back as long as he could, never wanting that moment to end, raping her hard and enjoying using the tight little hole that had been made for his cock. When he couldn't take it anymore, he buried his teeth on her neck, spilling himself inside of her.
He pulled out, got dressed, and freed her from the restraints. He had considered leaving her the way she was, but he wouldn't risk giving ideas to any doctor. He had made it very clear that Azula was his and his alone, but he'd rather not take the chance.
"Rest as much as you can, my love" Zuko said to her before leaving "I'll come see you again tomorrow."
