Chapter Text

It made no sense for Azula to care about him.

Her brother had always been too impatient, insecure, impulsive, and foolish to truly matter to anyone who didn’t share his weaknesses. He was the firstborn son of the Fire Lord - the true Fire Lord - yet he still walked around the halls of the palace like he didn’t belong.

Truth be told, Zuko had been an outsider long before exile. And in some ways, seeing him gone just felt right. He’d sail away, find some miserable Earth Kingdom village to live and die at, probably with a wife and kids, all destined to achieve nothing, just like Zuko himself.

What could such a weak, unworthy idiot have to offer to her, the crowned princess? She had everything he lacked, to the point that she’d some day rise to the throne, despite being the secondborn of a secondborn. She was born lucky, he was lucky to be born, just as their father once said. She was a prodigy that had achieved great things, while her brother had only managed to embarrass himself to the point of being sent away. He should have been easy to ignore, easy to forget.

…And yet there was always something about him.

It was completely illogical, but whenever he was around, the princess couldn’t take her eyes off of him. Couldn’t help but want to get closer. Couldn’t help but want to get him to react to her, even if said reaction was cursing her very existence for being everything he failed to be.

She supposed that him being attractive and having such willingness to keep trying, despite bitter defeat after bitter defeat, played at least some part of it, but there was no way it was all there was to it. 

Plenty of noblemen were good looking, and the Fire Nation army was filled with resilient, strong-willed, relentless soldiers - all of which would likely be harder to defeat than Zuko, even the ones that were weaker than him, simply because it wasn’t humanly possible to be as gullible as that dum-dum.

Her brother was the easiest prey in the whole world, and Azula simply had not been able to resist her irrational urge to sink her claws and teeth into him.

Getting exactly what she wanted from him was so ridiculously easy, to the point that it should have been boring, yet seducing him had been far more thrilling chasing the Avatar, getting him into her bed had been a much more satisfying victory than watching an entire kingdom be forced to submit to her, and, somehow, having him look at her like a lovesick fool was far sweeter than any praise father had ever given her.

And thus, here she is yet again, following him around the halls of the palace just to pull him by the hand to a more secluded, dark spot by the end of the hall.

He winces as his back hits the wall, and his eyes grow wide as Azula wraps her hands around his neck, barely even squeezing it, just feeling his heartbeat racing in fear and excitement. She lets go and allows her hands to slide down his chest and stomach, taking her sweet time feeling up every muscle, humming in appreciation.

“All the training seems to be paying off” she whispers “Maybe you’ll be a decent firebender someday, brother”

Her teasing immediately gets his entire demeanor to change, the pleading, eager look in his eyes replaced by pure vitriol.

“Go bother someone else” he rasps, grabbing ahold of her wrists, already bruising them slightly, forcing her to cease her touches.

His assertiveness only makes her need for him grow.

“We both know you don’t want me to do that” she argues.

“We’re not doing this anymore, Azula. It’s wrong.”

Hearing those words made her breath get caught up in her throat, heart beating impossibly fast, her hands shaking with need.

Zuko always fucked her harder when he was feeling guilty.

"You didn't let that stop you before. Why start now?" she tries to kiss him, but he turns away. As retaliation, she gently bites his cheek after her lips brush against it "We're royalty, we can do whatever we want"

"What I want is for you to disappear"

She laughs right in his face, then kisses his chin. He lets go of her arms and tries to walk away, but as soon as her hands start roaming his body again, he freezes on the spot, much to the princess's delight.

"You wouldn't say things like that if you genuinely didn't want me anymore. You know I like it when you get mean" she presses her lips to his neck before sucking on his pulse point, making her brother groan in pleasure and grab onto her waist, pulling her closer, his shaky hands slowly moving up her back.

"You're insane"

"And you're hard" she mocks, bringing a hand over his throbbing cock "So why don't you stop thinking so much and save us both the trouble of arguing?"

"Aren't you the one always saying I should stop being so impulsive?" he practically hisses, sliding one hand under her shirt, groping one of her breasts before twisting her nipple hard enough to make her tear up - which obviously just makes her more eager for him.

"You can be as impulsive as you want when it gives me what I want" she clarified kissing him hard and practically shoving her tongue down his throat, enjoying the way Zuko doesn't even hesitate to kiss back despite his ever-present need to be a martyr who is ashamed of existing.

They're forced to create some distance between themselves when they hear footsteps, and try their best to look like they're just having some a casual, normal conversation as some servants go over to their father's room with some wine and fruits.

Azula can only hold on a second longer after the girls disappear to throw herself at Zuko again, but he won't he won't let her kiss him again.

"This is beyond stupid. If we keep doing this, it'll only be a matter of time before father finds out"

She grabs ahold of his face, digging her nails into his skin as she forces him to look her in the eye.

"You have five minutes to get over yourself and come to my room"

His eyes widen in shock.

"It's too dangerous. Everyone is up. The guards, the servants, our father..."

"Do I look like I care?" she grabs one of his hands and makes him slide it under her hands and underwear, and Zuko practically growls as he feels how wet she is, allowing her to kiss him again and again.

"I'll come over tonight, when everyone's asleep"

"I'm not waiting this time, Zuko. You can have me right now, or you can spend the whole night having fun with your hand. Your choice"

She rushes to her room, well-aware of what her brother will choose.

When he barges in mere moments later, she has already gotten rid of her shoes, shirt and pants, so Zuko only has to strip her of her chest-bindings and wraps, and he doesn't waste a single second to do so, tearing them off before throwing her onto the bed and getting on top of her.

She really should remind him to lock the door.

She doesn't. 

Instead, she holds him close as he begins to practically feast on her breasts, kissing, licking, sucking and biting down hard onto them. He loves to leave marks on her, to the point that Azula now had to practice hand to hand combat a lot more so she has a decent enough excuse in case anyone wonders why she's always covered in bruises.

Her brother tends to be one practicing with her, of course. He's not one to waste a good opportunity to manhandle her.

And even though Azula adores that about him, she's not one to let him do that without pushback, if only to spare her pride a bit after being a bit too submissive for her liking. 

So, she forces her brother to stop his advances for just a moment, to get rid of his shirt. As soon as his mouth is back on her skin, she digs her nails into his back and makes it bleed. Zuko of course retaliates by bitting down hard onto her breasts before forcing her legs open so he can do the same to her thighs.

He presses an open mouth kiss to her cunt, lapping up her wetness just a bit before pulling away. Azula grabs ahold of his hair and desperately tries to force his head down again, but Zuko overpowers her and pins her wrists above her head.

"This is what you get for being a bitch. We're doing this my way"

"Ah yes, because we both know you hate eating me out, don't you?" she scoffs and the glimmer in his eyes makes it clear that, despite wanting to deny her, he is tempted to just spend half the afternoon with his face buried between her legs.

Wouldn't be the first time. Zuko had many flaws, but being a selfish lover was not one of them.

"Come on" she tries to goad him "Be a good brother"

He slaps her across the face with enough force that she can't help but cry out in pain and bring a hand over her cheek.

"How many times do I have to tell you not to call me that when we're doing this?" he scolds, trying to get up from the bed, but Azula won't let him.

"I'm sorry, okay? Don't go" she pleads, clinging to him "I need you so much, Zuzu"

He sighs, still angry, but finally gets rid of his pants.

They share a long, deep, passionate kiss before Zuko finally slides his cock into her. And as soon as he does, Azula can't help but tease him a bit.

"Does it feel good?" she asks, moving her hips "To be inside your own sister?"

He hits her again, but this time she just laughs, the sound quickly being replaced by desperate moans.

"I hate you" he snarls.

"I know. That's what makes it fun"

Zuko's movements become more and more violent, his cock sliding almost all the way out before he slams the full length back into her pussy, making her gush.

"Fuck, that feels so good" she says, with some difficulty as the brutality of Zuko's movements makes it hard to breathe, or think "I knew you'd be good to me, brother"

"Shut up!" he says, wrapping his hands around her neck and choking her as he continues to pound her without mercy "I don't want to hear another word from you, understand? Don't force my hand, Azula" 

She just nods, genuinely shocked and trembling even once Zuko lets go. They were always aggressive with each other, but she had never feared him before - and some sick part of her loves it.

The idea that only she could get him to truly lose himself, that only she could bring out the proud, arrogant, dangerous prince that hid behind that mask of honorable, unworthy fool, that only she, as his sister, could make him a man... words could not describe how aroused it made her.

And maybe that was the simple truth behind it, wasn't it? Of course no one else could catch her eye. Of course no one but her own brother could reduce the proud, ruthless prodigy of the Fire Nation to just a desperate, needy, lovesick girl. Of course she didn't care if they got caught.

They had the same blood. They were mated for life.

She keeps her mouth shut as Zuko continues fucking her, biding her time until they're both on the edge of their shared climax.

"Cum for me" she begs, holding him tight, moving her hips to try and get him to go as deep as possible "I want feel my big brother cumming inside me"

He growls in her ear as he gives her just what she asked for, pushing her over the edge as well, her orgasm crashing over her with such force she fears she might pass out for a moment, clinging to her brother like her life depends on it.

She struggles to catch her breath after it. Never, ever in her life had Azula experienced something so good, so intense, so right.

Judging by the way Zuko got hard again while still inside her and almost immediately went back to fucking her, the princess thought it safe it assume he felt the same.

She would absolutely use that to her advantage the next time her brother wanted to resist her.

If she survived this afternoon.

Chapter Text

Azula really should have known better than to pick up a fight with her brother. Or at the very least known better than to let him go home to his own place without some much needed make up sex. Or break up sex, didn't really matter, as long as Zuko ended up in bed with her.

But no, she just had to hold onto her pride and pettiness, pretending arguing hadn't always been foreplay for them.

And so she paid the price, waking up all sweaty and desperate, moaning his name while grinding pathetically against the bedsheets between her legs, shaking as she practically bit down on the pillow she was clinging to, feeling as if her whole body was on fire.

Her panties and shorts were pretty much unsalvageable after how absolutely soaked her cunt got because of that dirty dream - which was rather ironic considering that, in said dream, Zuko had been teasing her clit ocasionally, but was much more focused on finally being allowed to fuck her ass.

She had to admit, it did make her feel a bit silly that the very thought of something had always seemed terrifying to her before, due to nature having been very generous with her brother when it came to his size, had now given her what was probably the most intense erotic dream of her life.

Yet the sudden, unexpected release left a bitter taste in her mouth since Zuko wasn't there to truly make love to her like he had been in her imagination. It just didn't feel right to not have his arms around her, holding her close, all tender and possessive as she recovered. To not have him kiss her face and neck, whispering sweet nothings to her, or getting all cocky about how much he made her scream.

Imagining it might have been more than enough to get her off, but only the real thing would be enough to truly satisfy her.

Still feeling like the biggest idiot on the planet, she decided to wave a white flag by calling her favorite moron.

"What is it you want now?" he asked, clearly annoyed and wanting to go back to sleep "One shouting match wasn't enough?"

"I can't sleep. I want to be with you"

"That's not my problem" he answered bluntly.

"I can make it your problem" Azula warned, her free hand already sneaking under her clothes.

"I'd like to see you try" he scoffed.

Big mistake.

"I bought a few things for us try on before you decided to pick up a fight"

"You started it" he argued, but it didn't take more than a few seconds for him to take the bait "What things exactly?"

"Oh, nothing too fancy. Just candles, handcuffs, blindfolds, that kind of stuff" her words were cut off by a breathy sigh "Oh, and of those Cat Woman costumes you always said would look good on me"

"...Really?" Zuko asked, trying, and failing, not to sound too eager.

"Uh huh, the mask looked really cute" she sighed again, and this time there was a pathetic whimper on the other end of the line "I didn't really like the rest of the outfit though, think I might give it back"

"Why?!" this time he didn't even try to mask his disappointment.

"It was way too tight"

There was a long pause before he finally asked, in a low, breathy tone that made Azula wonder if he was touching himself as well.

"How tight exactly?"

"Why do you want to know? I thought this wasn't your problem"

"Answer the damn question, Azula"

She chuckled, all too pleased with herself.

"Tight enough that I struggled to breathe and my chest hurt after trying it on" she moaned a little this time, making sure to rile her brother up as much as possible "It was really hard to move with it. It'd have probably ripped at the crotch if put me on all fours"

He growled in frustration and she knew she won.

"I'll be there in ten minutes, and you better be wearing that damn costume"

"Gladly"

He really would be disappointed once he realized there was no costume, but Azula could make it up to him by buying one the next morning.

And by telling him the good news of what he'd be allowed to do to her from now on.

Chapter Text

His sister had always been beautiful. Even when their rivalry was at its worse and Zuko felt like he genuinely hated her, he was still unable to deny that simple fact. Azula had been blessed with what he could only describe as the ideal look.

Long locks of dark hair, pale skin, blushing cheeks to match her red lips, and brown eyes that seemed to turn golden in the right light. Petite and delicate, yet with nice curves that always caught his attention - long legs, thick thighs, tight little ass, and breasts that practically seemed made to fit in his hands.

No one could blame him for noticing. It'd take a lot more than shame and taboo to make him blind to the obvious. And once she made it clear she was willing to let him do a lot more than look, well, he couldn't bring himself to say no. What kind of man would he be if he had, really?

And he's a good boyfriend to her too, always loving, always by her side, and, of couse, buying her pretty little things to make herself look even nicer - even if most of these gifts were the kind she could only wear when no one else was around.

"You look so good with these" he says, gently pulling at the pearly string attached to the clamps on her nipples, loving how the little buds seemed to be practically begging for more of his attention, as he had already stimmulated them quite a bit before putting the clamps on.

"I look good in everything" she responds like the brat she is, earning a slap on the ass that only seems to please her.

They kiss each other deeply and Zuko pulls her over to his lap as he sits down on the couch. He's still dressed, but his sister is fully naked. He prefers it that way. He might have zero shame over being nude in front of her, but having her be the only one fully vulnerable and exposed adds to thrill of it all for him.

He kisses, sucks and bites down on that pretty neck, loving the way it makes Azula squirm above him, her arms pulling him closer. His kisses go a bit lower, to the top of her breasts, which he wastes no time groping.

For once, Azula doesn't seem too pleased by it, the clamps clearly giving her some trouble, her nipples so hard and red. Each time he gives one a gentle flick, it makes her cry out. 

"You're gonna have to put these back on later" he teases her nipples again, and she slaps his hands away before briefly pressing her lips to his "Such a lovely sight deserves a picture"

"You're lucky I agreed to this at all" she says between kisses "It hurts"

"Come on, we both know you're not afraid of a little pain" he gropes her pretty tits before giving a slight pull at the string, making her wince but still grind against him a bit.

"Just 'cause I'm not scared doesn't mean I enjoy it"

"Liar" he proves his point by slapping her hard on the ass, making her moan "See? You can handle it and you like it. You just need to get used to these now" he tugs at the string again, with a bit more force this time, but still being very careful.

"You're lucky I like making you happy" she whines.

He can't argue with that.

"Good girl" he kisses her cheek "If you endure it for a bit, I'll make sure to give you a nice reward after. I'll even let you choose what you want me to do to you"

"Really?" she's immediately excited and leans in to whisper in his ear "Then I think I'm gonna sit on that face for a while" 

She bites his earlobe and he pulls at the string again, making her hiss. Their lips find each other again, one of his hands working it's way between her legs, his fingers rubbing her clit before pushing inside.

He thursts his fingers in and out of her for a bit, feeling her tremble in arms, hearing her moans, and seeing her blush adorably. Each time he gives the string another pull, she cries out or bites her lower lip in appreciation, her walls tightening up around his fingers, her wetness coating his hand. The obvious mix of pleasure and discomfort on her face makes his cock throb;

Eventually he decides to take pity on her and removes the clamps. Azula sighs in relief, then laughs as Zuko starts kissing her sore nipples.

"Do I get to enjoy my reward now?" she asks, raising an eyebrow.

"Only if you thank me for clamps later" he says, forcing three of his fingers into her mouth, forcing Azula to taste herself, giving her an idea of how exactly she could thank him.

She bites down on his fingers before sucking on them sensually - and to his surprise, she decides to play nice and gets down on her knees before him, wasting no time freeing his cock from his pants and taking it into her mouth.

She definitely earned more than just one reward with that. Nothing got to him quite like seeing Azula be all obedient and eager to please.

Her hands toy with her breasts, massaging them a bit, nails digging in, her fingers pinching her already abused nipples. She moans and drools a bit over his cock, the wet, obscene sounds encouraging Zuko to thrust into her mouth as far as he can go, hitting the back of her throat, making her gag and chock.

Through it all, Azula just continues to suck him off while putting on a little show for him.

It's definitely going to be a fun night.

Chapter Text

Getting a rise out of Zuko had always been the easiest thing in the world, and one of Azula's favorite passtimes since she was a child. Falling in love with him had done nothing to change that - if anything, it made her double-down, since now Zuko wouldn't deal with his frustration at her taunts and schemes through screaming matches and physical fights, but by having his way with her to remind her who was in charge.

Naturally, that meant the best time to tease him was always when he couldn't do anything about it. During meetings or feasts in which he had to keep up the appearance of calm, collected Fire Lord, or simply when he was too busy with something else (and thus not giving her as much attention as she'd like). The more inconvenient, the better.

So on their wedding day, with her hair partially up in a top-knot, a few locks cascading down her shoulders, and make-up perfectly done but without wearing her dress just yet, a simple red robe being the only thing giving her some modesty, the soon-to-be Fire Lady decided to pay her soon-to-be husband a quick little visit.

He was fresh off the bath, hair still a bit wet, wearing only some nicely fitting black pants. All the rest of his clothes, including the cape, shoulder pads and crown were being neatly placed on the table before him by the courtiers, whom Azula immediately asked to leave the room.

"Is there something wrong?" Zuko asked, visibly nervous.

"Oh no, my love, not at all" she waited until they were alone to continue "I simply wanted to make sure that what I'm wearing is to your liking" she undid the sach of her robe and held it open so Zuko could see what she had underneath.

His eyes went wide and his face got red at the sight of her practically see-through white underclothes, his gaze taking it's sweet time moving from her breasts down to her stomach, hips, and pussy before briefly settling on the little lace garter on her thigh, then going all the way back up again until their eyes finally met.

"So? What do you think? I would hate to disappoint you on such a special night, my Lord" she walked up towards him, throwing her head back a bit "I even put on some new perfume. Do you like it?"

He answered her question by leaning in and breathing deeply before fully burying his face in the curve of her neck, kissing it while his hands found her hips.

"I'll take that as a yes" she chuckled and him pull away briefly "You should get dressed now. A Fire Lord shouldn't be late to his own wedding"

She pressed her lips to his for a quick kiss and turned around to leave, but Zuko just pulled her back, holding her tight, on hand on her waist, the other on the back of her neck. He shut her up with a deeper, slower kiss before she could complain, and it felt so good, Azula actually forgot herself for a moment. 

It wasn't until she felt Zuko pulling at the pins keeping her hair in place that she remembered they were supposed to save all this passion for their private moments after the ceremony.

"Wait!" she complained, slapping his hand away "Don't do that!"

"Ssshhh, you can have it fixed later" his warm breath and soft lips found her neck, and she'd be lying if she said those fiery, tender little kisses weren't tempting her into ignoring all reason.

"Zuko, we need to get ready"

"You should have thought of that before letting me see you in these" he argued, groping her ass and one of her breasts through the thin fabric covering them.

"Fine, fine, I won't do anything like this again, now go get dressed" she commanded, trying to push him away, but he was not having it.

Zuko forced her against the wall, her face and the entire front of her body pressed against it while he pinned her hands behind her back, trapping her. When he undid her top-knot, letting her hair down and pulling at it, she tried to kick him in the shin, but he had been expecting it and not only managed to avoid it, but also responded to it by putting one leg between her's, his knee pressing against her clothed cunt, and she couldn't resist the urge to rub up against it.

"Needy little slut" he taunted.

"Stop"

"Make me" he let go of her arms, knowing she'd stay where she was.

He kissed her nape, her shoulders, her back, her hips, the curve of her ass, and her thighs, then stood up again, playfully biting down on her neck before pulling her panties to the side, sliding his fingers through her slit.

"You want it so bad, don't you?" his arrogant tone only made her wetter "Who am I to deny my Fire Lady?" his expert fingers rubbed her clit in fast, circular motions "It is my job to tend to her every need"

She moaned and parted her legs a bit more. Zuko continued teasing her for a bit until her wetness was dripping onto the floor, then pushed two of his fingers inside of her, each little movement gentle yet so precise it made her see stars. He already knew all of her favorite spots, and exactly how to touch her and when.

"She please..." she said between sighs.

"'Please' what, Azula?"

"Let me look at you"

He pulled back and allowed her to turn around. She embraced and kissed him, feeling him smile against her lips.

He exposed her breasts and brought his attention back down to them, feverishly kissing them both, covering them in hickeys and bite marks - good thing her wedding dress wasn't too revealing.

She grabbed his hand and brought it back to her pussy, making him rub it. He laughed and knelt before her, removing the garter and panties with his teeth before throwing one of her legs over his shoulder and pressing an open-mouth kiss to her cunt.

"Fuck" Azula breathed out, running her fingers through his hair.

She could feel him smiling once again and looked down at him. His wicked eyes meet hers right as he pulled his cock free from his pants, stroking it, and she just threw her head back, surrendering to the pleasure that only her brother can give her.

He lapped up at her cunt greedily while she pressed her hands to the wall, trying to keep herself up. It got even more difficult when Zuko decided to throw her other leg over his shoulder. When he stood up, lifting her along, she couldn't help but squeal in both delight and in fear of falling, struggling to keep her balance, uselessly trying to hold onto nothing while her show off of a brother continued to eat her out, sucking her clit into his mouth while supporting practically her entire weight.

"Put me down" she complained between cries of pleasure, pulling at his hair "Now is not the time to risk breaking any backs or twisting any ankles"

Reluctantly, he brought her down again, allowing her feet to touch the ground for just a moment - but as soon as she laced her arms around his neck, he grabbed onto her legs again and wrapped them around his waist, keeping her pressed between the wall and his body. Azula kissed him passionately as Zuko slide his cock into her.

It'd never cease to amase her just how much of a perfect fit they were.

Every little thrust stretched her deliciously and she couldn't help but move her hips wildly, trying to make sure he was back inside just a little bit faster, even if just by a fraction of a second. It made her feel a little pathetic, yet there was no doubt in her mind that it was worth it. The looks of pleasure on his face and the grunts that escaped past his lips each time she'd tighten up around his cock confirmed to Azula that Zuko agreed.

He practically crushed her against the when he slammed his entire length into her as far as it could possibly go, bringing tears to her eyes, the two of them panting, moaning and struggling to catch their breath as they reached their climax together.

As usual, Zuko doesn't pull out immediately, allowing the moment to linger a bit longer, the two of them savoring the feeling of being so intimately connected.

When they finally part, Azula can't find it in herself to care that her hair is a mess and her make up is ruined, and that the ceremony will likely have to start a bit later than expected. She only bothered to fix her underwear and put her robe back on as to not to waste a single drop of her brother's cum, and so no other man gets to see how desire still seems to radiate from her body - such a sight is meant for Zuko's eyes alone.

And as she looked back at said eyes one more time before leaving the room, she saw a silent promise for many, many more moments like this.

Not just that night, but for the rest of their lives.

Chapter Text

They both wanted that night to be special. It had been exactly one year since they confessed their feelings for each other, and they were in a joyous, celebratory mood, and planned ahead to be able to spend the whole day together, clearing their schedule completely. 

Azula had decided that waking him up with a blowjob would be the best way to extra sure Zuko would be in an excellent mood, and she had been 100% right.

He had always been a grumpy, impatient, difficult person that could be ticked off by anything and everything, but it was impossible to have any negativity in him when he woke up already on the edge of a climax, pulling the sheets away to see his beautiful, bratty little sister sucking him off like her life depended on it, letting the head of his cock hit the back of her throat and using her hands to tease his balls and the few inches of his cock that she couldn't get into her mouth no matter how hard she tried.

Of course he went down on her too once she was done.

With that out of the way, it was time for their real (thought less fun) breakfast, which they cooked together. Toasts, scrambled eggs, sandwiches, pancakes, coffee, juice, yogurt, fruits and anything else they felt like putting on their plates, or stealing from each other.

Miraculously, getting it all set up hadn't turned into a full-on food fight, just some light teasing. Azula ended up with a bit of butter on her forehead and jam on her cheeks, to which she retaliated by blowing a bit of flour right at Zuko's face, which led to a coughing fit.

They cleaned up the mess and headed to the bathroom to shower together, then got dressed. They exchanged gifts - esmerald earrings for Azula and a diamond-encrusted watch for Zuko - then headed out.

The pair drove around all day and made the people absolutely sick with both their bickering and shameless PDA at the mall, at the bookshop, at the cinema, and at the park. Zuko could see the annoyance on the face of the whole staff of the restaurant they had lunch in when they came back later for dinner. 

When they finally came home, they were both tired, yet eager for more fun.

Since, for once, they hadn't just looked for secluded spots to have sex at everywhere they went, all of the lust that had been building up and up all day due to the passionate kisses, sensual touches and sweet, dirty nothing whispered in each other's ears was more than enough to keep up for as long as it took to satisfy that craving. 

Zuko was hugging her from behind and kissing her neck as Azula locked their front door. When she turned around, their kiss was all teeth and tongue. They removed their jackets and kicked off their shoes as they made out. Zuko tried to push her down onto the couch, but she didn't let him. 

Frustrating at it was, he understood why. If she let him get carried away, there was no way he letting her up until he was satisfied, and they'd be too spent to do what they had planned.

Zuko headed to the kitchen to double-check if he had everything they need in case something went wrong - a small fire extinguisher, a simple first-aid kit, and a bucket filled with cold water and ice cubes, which he dipped a towel into - and took it all to their bedroom, where Azula had already turned off all the lights and lit four candles up, away from their bed.

Atop the mattress were four old black ties and a blindfold. And on the dresser on the left side of their bed, with easy access, was a knife in case he needed to cut the ties off in a hurry, and a fifth, special candle made solely for what they were about to do. 

His sister practically leapt into his arms, and he gladly caught her, kissing her deeply once again, his tongue toying and sparring with hers, and she'd moan into his mouth each time he'd grope her ass or breasts. She snuck her hands under his shirt, feeling up all the muscles on his chest, abdomen and back.

When she undid his belt and teased his cock over his pants, he rewarded her with a bite on the neck. As he sucked on her pulsepoint, making sure to leave a nice little mark, she tore his shirt off.

"Good thing you bought me some new ones today, or I'd have to whip you for this" he teased, completely unable to pretend he was actually mad as he unzipped her dress and watched it fall to the floor "I bet you'd look real pretty with some red welts on your ass"

"Tell you what" she said, pulling his cock free from his pants and underwear, teasing the head a bit "If you like the idea so much, we could try for it for our two year anniversary"

"What if I don't wanna wait that long?" he asked, nipping at her lower lip.

"In that case" she gaves his cock some long, slow strokes "Make me scream a lot tonight, and you can do it as soon as you get the whip"

"Promise?" he asked, already on the edge after a whole day of teasing.

She nodded, offering him that sinful smirk he knew and loved as she continued to stroke him "You know I'd never say no to my big brother"

"Even when he wants to hurt you?" 

She leaned into whisper in his ear "The more it hurts, the better"

He held onto her as he came, spilling himself against her stomach, grunting and panting as she pumped his cock until it softned.

Azula licked her hand clean, then used a tissue to remove the rest while Zuko tried to catch his breath.

"Hope you can still keep going, dum-dum" she teased.

"You know I'd never leave you unsatisfied" he grabbed her by the waist and pulled her close to himself again, kissing her shoulders and collarbone.

When she unhooked her bra, he pulled it off to expose her tits, which he eagerly kissed as he pulled down her panties, leaving her fully naked before him.

He kissed her over and over, letting his hands roam her body, loving the way she was panting for air each time he'd pull away for a bit, his cock already beginning to throb again. 

Once she was ready, she knelt before, taking off his pants and underwear, giving his cock a few kisses and licks so it'd be hard again.

She got back on her feet, allowing Zuko to blindfold her and then lead her to the bed, where he tied her up, arms and legs open wide. She looked so beautiful like this, vulnerable and exposed.

He took the candle from the dresser and put a finger into the pooled wax, then poured some of it over his knuckles to test it out first. It was just hot enough to be painful, especially for someone as sensitive as Azula, but it was not likely to cause any burns.

Still, to be extra careful, he brought the bucket filled with ice closer, then brought the candle close to Azula's arm, as the first and only warning she'd get that they were about to start, and of where he'd drip wax on.

She took a deep breath and bit her lip. Zuko allowed the first drops to hit her forearm. Azula hissed, then let out a pleased sigh. Zuko did it again, earning the same result followed by a sweet smile. He gave her other arm the same treatment, still being careful and paying close attention to each one of Azula's reactions.

Taking a step further, he let a bit of wax drip down onto her belly. This time, Azula let out a little yelp, but the pain didn't seem to be more than what she could handle. He poured some more over her stomach, watching with fascination as it'd drip down her sides and harden right before reaching the bedsheets.

He brought his attention back to her arms for a bit, not caring about making a mess, pouring generous ammounts - then doing the same to one of her thighs, loving the way Azula would cry out and throw her head back in pleasure. He did the same to her other leg before pouring a few drops on her belly again, slowly going up and up towards her breasts.

She let out a breathy sigh as the first drops of wax hit one of her nipples, and it was quickly followed by sensual, needy moans as he'd pour and more onto her tips. He put the candle back on the dresser before the wax fully hardened, massaging her breasts for a bit. Azula bit her lip to keep from moaning, then let out a giggle.

His wax-covered hand cupped and caressed her cheek, and Azula kissed it gently.

"Come here" she asked.

He did - but not without first putting one cube of ice in his mouth, then grabbing two smaller ones. Azula squirmed underneath him as the first drops hit her tits and neck, moaning and sighing in pleasure.

"And you call me a tease"

Takes one to know one, he thought.

He rubbed the two smalls cubes all over Azula's body - arms, neck, collarbone, breasts, belly, hips - taking his sweet time, waiting for them to disappear, ocasionally making some of the hardened wax peel off. He then took the partially melted cube out of his mouth and rubbed it against one of her thighs while kissing her cunt, each little movement from his lips and tongue making Azula go wild.

Once she was absolutely soaked, her body practically on fire with need, Zuko finally pushed his cock into her. Azula cried out, then smiled and uselessly tried to reach for him despite the ties keeping her in place. Zuko just grabbed her hips and gave it to her hard.

He had already made her sigh, moan and cry.

It was time to get her to scream.

Chapter Text

Zuko had promised her he'd on his best behavior that day. He had meant it too, after all they were still hiding their relationship, and discussing when would be the best time to make it public, and how. That would all go out the window if he got too handsy with his sister in front of everyone at this picnic.

But the two of them had all alone in the hot air balloon, Azula's perfume was so good, she looked so cute in her little summer dress, with the wind and sunlight in her hair, showing a bit more skin than she had intended when she crossed her legs, and the way she was sucking on her fingers after eating some of the fruit she had taken from the huge basket they were bringing... he simply hadn't been able to help himself.

He hugged from behind as she was about to blast a bit of fire into the tank keeping the balloon up in the sky, startling her, then kissed her exposed neck and shoulders.

"What are you doing, dumbass?" she whined.

"You know what I'm doing" he gropped her breasts through her dress "And I know you like it"

"Zuko, not now" she tried to walk away, but he just pulled her back to his arms, holding her tightly "Dum-dum, we're almost there"

"But we still got a few minutes here, where nobody can see us" he argued as he pulled the top of her dress down, exposing her breasts

"Stop that!" she tried to slap his hands away, but it was useless.

"No" he pinched her nipples "You're too pretty for me to resist"

She sighed, half annoyed and half flattered, as he fully gropped her again, massing and teasing those heavenly tits.

"You're unbelievable" she chastised as she leaned in for a quick kiss "You're lucky I don't say no to my Fire Lord"

Once he stopped touching her, she knelt before him, pulling his pants and underwear down slightly, running her hands through his cock, ocasionally teasing the head.

"If you make a mess of my dress or my hair, I will kill you" she warned.

"Won't be a problem" he pushed his thumb into her mouth, smirking as she bit down on it "If you swallow it all like a good girl"

She rolled her eyes at his words as his thumb slide down her slow lip, but he could see that cheeky little smirk she tried to hide as she got to work. Zuko gave one look around, making sure they weren't about to crash on some tall trees, then looked back at his sister.

Azula gave his entire length broad, sloppy licks, getting it slick, then stroked it again as she eagerly sucked on his balls, making sure that her tongue was giving them quite a lot of attention before switching tactics, fondling them with her clever little hands before opening her mouth wide to take his cock into it. It felt sinfully good.

He gave another look around and decided their balloon was getting a bit too close to the trees, so gave the tank a small blast, looking around again as it went, rising above the trees and most birds - then hissed as he felt Azula's teeth gently (but not that gently) pressing down on his cock.

Then angry glare on her face said it all: this was your idea, so now you better keep those eyes on me.

He did. Gladly.

Azula was giving him the most ridiculously sexy looks imaginable as she went down on him, those pretty lips teasing every little part of his cock, first allowing him to go deep, causing his cock brush against her throat repeatedly, then focusing more on sucking, kissing and licking the head, teasing the tip, then sliding further down again.

He had to awkwardly support himself by grabbing onto her shoulder with one hand, then placing the other on the tank. Azula suddenly went as far as she possibly could, holding onto his hips and butt as she allowed him to practically fuck her throat, his cock making her gag, choke and drool. Zuko swore his vision went dark for a second there. It had to have been the best blowjob Azula had ever given him, and that was saying something considering how good she had been at it from the start.

They both held still as he came, and were then desperately panting for air as they finally separated, Zuko still awkwardly leaning against the engines of the balloon, Azula laying back on the floor.

"I think..." she was still struggling to breathe "Doing this... at this alti...altitude... wasn't that... great of an idea"

"I don't think... I ever... disagreed... that much with you"

They both laughed, which didn't exactly help with the lack of air, but once they regained their composure, Zuko helped her up, and the two of them just quietly cuddled as they wanted for their balloon to reach it's destination. 

No one else had made it yet, so they just started setting up stuff, laying down the huge picnic towel, then placing some plates and cups atop of it, but not taking any of the food out of the basket, deciding to wait for the others.

But it seemed they were taking their sweet time, and Zuko couldn't help but notice the way Azula was looking at him, and mentally chastised himself for not having made his move sooner, so they both could have been fully satisfied far, far away from any prying eyes.

Well... he had a made a promise to no longer be a selfish, spoiled person who only did things for his own benefit, right? He had the moral obligation to do something about this.

He grabbed Azula by the wrist and started leading her away to a more secluded spot.

"Where are w-"

"Shut up"

She did. And once they were a bit further away, surrounded by some very large trees, she merely squealed as he grabbed a hold of her and then pinned her to the ground.

"Seriously? Again? I thought you had enough" despite her words, there was zero disbelief in her voice.

"I was being a neglectful brother" he lifted up her dress and forced her legs open so he could between them "Had to fix that immediately"

"Zuko I'm fi-oh!" her words were cut off by a desperate moan when cupped her cunt over her panties.

"Doesn't look like it to me"

She blushed "Just 'cause I can control myself, doesn't mean I don't get tempted"

"Right, you got perfect impulse control" he teased, pushing her underwear to the side to touch her directly as he kissed her neck "Which is why you're letting me do this out here, where is much more dangerous than in the balloon. You're not at all needy"

"Shut up" she said, pulling down the top of her dress to expose her breasts as an incentive, and then grabbing him by the hair to bring his face close to it.

Who was he to deny his princess?

He lavished her tits with as much attention as possible, taking turns franctically kissing them or sucking them into his eager mouth, his tongue and teeth ocasionally teasing those hard, sensitive nipples. All the while, his fingers would teasingly rub her little clit, or push into her waiting hole, feeling her clench down on him, clearly craving something bigger.

She didn't have to wait long. As soon as he was sure she was properly prepared, he freed his cock from his pants and pushed into her tight cunt. He grabbed onto her hips as he gave it her hard, and Azula would moan, scream and cry out his name as he pulled almost all the way out just to slam his full length back in. He angled it just right to rub up against her each time he was back in, making Azula desperately try to grab onto the grass and earth underneath her.

It wasn't long before she was shaking due to the intensity of her orgasm, and the sight caused Zuko to carelessly spill himself inside of her.

They kissed and cuddled on the ground for a bit before reluctantly getting up and trying to adjust their clothes - and to get all the grass off Azula's hair and dress. Considering there were no more threats of murder despite the mess, Zuko took it as a sign she had been needing that even more than he first assumed.

The two were heading back to where the others were supposed to meet them, only to find Toph sitting on a rock not more than a few meters away from where they had just made love.

"Hi, Zuko. Princess" she smirked.

"H-Hi" Zuko had tried really hard not to panic "How... how long have you... did you... what did you see?"

"Nothing, as usual" Azula deadpanned, having to jump away from a rock that was aimed at her face.

"As your sweetheart of a sister so kindly put" Toph began to answer "I've turned a blind eye to everything since I was born, and I don't feel like changing that now. As long as you're ready to finally have a life-changing field trip you owe me"

"He's the Fire Lord" Azula scoffed "He can't waste his time running around the Earth Kingdom just to amuse you"

"Then I can't promise I won't tell anyone about the little... earthquake I witnessed" Toph smirked again, knowing she had own.

Azula just pouted "Can I at least come along?"

"Sorry, princess, but these trips are about finding inner peace, and based on what I just heard, you clearly don't know how to come quietly"

Azula's jaw dropped and her cheeks got even more red than her dress. As for Zuko, he tried with all his might not to laugh at the joke his friend had made at his sister's expense.

He failed. Miserably. And earned himself a slap to the face.

It was worth it.

Chapter Text

Azula had always understood how things worked for royalty. They were better than everyone, and thus they were above everyone. They had privileges that peasants and even nobles couldn't even dream of, and should never even aspire to, as they'd always be unworthy of it all.

But royalty also had obligations, a standard to uphold, roles to play expertly - both in public and private, and they were not the same for each of them.

The Fire Lord, of course, had the most obligations of all, just as he had the most privileges. The crown was a blessing, but a heavy one that would turn into a burden if the wrong man (like grandpa Azulon or uncle Iroh) were to sit on the throne.

Still, a prince was never to never to challenge the Fire Lord, just as a son was never to insult his father, and a secondborn was never to eclipse the firstborn. But if someone were to fail to live up to their role, the rest of the family should step in to correct that, through whatever means necessary. After all, correction would never be the same as treason.

That had been how Azula's father won the throne that should have belonged to his older brother. 

And so, Zuko had become heir and had to learn how to act like one. 

Azula helped him out, against her better judgement and her brother's own wishes. A firstborn needing the help of their younger sibling was embarrassing enough, but a prince needing a princess's advice was downright comical. But it had paid off, for he became more cunning, more ambitious, more careful and more patient. Zuko slowly but surely became greater than anyone could have predicted.

So great, that he dethroned his own father by conspiring with the enemy and steal Ozai's crown.

Azula struggled to forgive him for it at first, but was eventually forced to accept that this had been an inevitable consequence of her guidance. The perfect princess had created the perfect prince. She had taught him everything - including things a brother and sister should never engage in.

Zuko had been more than willing, and it made some sense. Men were supposed to have strong urges, and princes were allowed to indulge in their desires freely, constantly. They were not to be ruled by them, of course, but the more a man accomplished, the more he was entitled to demand.

However, princesses were expected to always be innocent and proper. Beautiful to look at, but to earn respect they had to seem not only out of reach, but also uncorruptable, prudish, or even frigid. Men married them out of duty or ambition, but never in the hopes of a passionate marriage, as sex with their husbands would be something princesses were taught to endure, not enjoy. 

Yet Azula, perfect little princess that she was, simply didn't have it in herself to meet that expectation, and had realized so from a very young age. And so had her brother, who had always been the one she couldn't keep her hands off of.

She had been possessive of Zuko for as long as she could remember, becoming violently jealous if any of her friends, of the noble ladies, of the servant girls, or even their own mother paid him too much attention. She wouldn't accept anyone else being his favorite woman in the world.

Azula had also grown to resent his teachers and masters, despite them being mostly men, for stealing away precious time he could have spent with her. 

Zuko's close bond with his stupid foreign friends and with uncle Iroh bothered her deeply for the longest time - especially since the latter was quick to notice something was off about their relationship and tried to keep them apart.

The princess would never admit it, but even her father had become an obstacle, perhaps the greatest of them, in her mind, for the exile imposed on her brother.

But those three years hadn't changed anything. The ending of their childhood had been marked by stolen kisses, longing glances, lingering embraces, various stages of undress and wandering hands, and all of it came back full force when her brother finally returned. He had taken her to bed countless times before either of them became an adult.

Azula knew it was supposed to be wrong, but was always more than willing to break every rule when it came to him - mostly because it had never felt wrong.

Whenever they were together, she was eager, passionate and wild. She had never said no to anything he asked of her, and was not shy about her own fantasies either - most of which included enduring some form of humiliation or physical pain as a way to show her devotion.

But Zuko was all about control.

That's why he had forced the whole world to swallow their cries of outrage when he took her as his wife - and why he never stopped finding new ways to remind her who was in charge.

"Is this really necessary?" she asked, pouting and crossing her arms "You know I'd never let another man touch me"

"Is is necessary because I know how hard it is for you to resist teasing yourself" he argued as he locked the chastity belt in place "And no one gets to please you but me"

He pressed feverish kisses up and down her thigh while one of his hands cupped and massaged one of her breasts. Azula could feel her body react, yet when her brother pressed on the steel covering her crotch, Azula whined in frustration.

"Come on, this is not fair!"

"I decide what's fair" he bit down on the inside of her thigh, making Azula burn with need "And I say it's more than fair to expect the Fire Lady to learn how to control herself" he pressed one last kiss to her skin, then did not touch her for the rest of the day.

At first, Azula had hated that chastity belt more than words could have possibly described. The loss of control, the building frustration, the embarrassement of having to ask for Zuko to hand her the key whenever she needed it off - it all made her furious. And whenever she got too bitchy for his liking, Zuko would punish her by continuing to deny her, even they were in bed together and goddamned belt had been removed for many hours. He'd make her suck him off, and then not do anything for her, to remind her the purpose of this entire thing.

But if she behaved well, or Zuko just felt particularly generous, he'd tease her with his fingers, eat her out for what felt like hours, and then mercilessly thrust his cock into her until she was a moaning, trembling mess. Sometimes he'd surprise her and have his way with her while she was still asleep.

He had been kind enough to make a back-up key that was in their room at all times, and that Azula was allowed to carry in her pocket if she ever needed to go out without him. But Zuko made sure to sneak up on her randomly, to check lift up her skirt or force his hand inside her pants to make sure she truly was only ever using that key for emergencies, not to trick him and avoiding wearing the belt altogether.

Zuko clearly felt like he owned her body know, and that deliciously perverse thought was exactly what made Azula grow fond of the chastity device. And he rewarded her for fully embracing the idea at last.

He'd randomly give her 'off days', or remove the belt long before bedtime to have his way with her instead of just demanding a blowjob, and whenever he had to go on an adventure with his friends, she'd be at the palace, not only without the belt, but with full permission to take care of her needs - as long as she used the toys that had been molded after Zuko's cock. 

Her pleasure as his property as much as her body was. He'd be the only one to satisfy her, even if from afar.

Finally, after nearly a full year of this little arregement, Zuko decided to give her the ultimate sign of trust by allowing her to keep the back-up key at all times.

"There's no need for it" she argued as they cuddled in bed, both already fully naked.

"I want you to have it. You've earned it" he pressed a kiss between her breasts, right above her heart "All I ask is that you still only use it for emergencies. Always come to me first when you want to take the belt off"

"Of course" she ran her fingers through his hair, giving him a few gentle scratchies "Thank you for taking such good care of me, dum-dum"

"It's my duty as your husband" he tapped one of her thighs to let Azula know part her legs so he can get between them, and she didn't hesitate to comply "And as your brother"

The two smiled sweetly at each other and Azula pulled him for a passionate kiss, loving the way his hands didn't stay put for a second, roaming her body without a care in the world. It felt so good, and combined with the growing need she had through the day, it made her hungry for more of his touch.

"I saw the way you were looking at me during the meeting" he had said as he rubbed small, slow circles on her clit "You wanted some attention, didn't you?"

"I did" she admited, spreading her legs as far as they could go in a display of further submission to him "But I knew I shouldn't distract you"

"Good girl" he praised as he slip two fingers inside of her "You have permission to get a little bratty next time you feel like it. It'll be your reward for today"

"You're spoiling me too much, my Lord" she teased "If this goes on, I might be the one needing to teach you to control your urges"

He removed his fingers from her cunt and slapped her across the face, making her moan, then forced his cock into her.

"You don't get to deny me anything, ever, understood?" his words were backed by his fast, brutal movements that make Azula feel like she might break "You just do as you're told like a good slut"

She moaned and wrapped her arms and legs around him as she moved her hips wildly, trying to get him as deep as possible. The feeling was almost too much to bear after such long periods of denial, but that just seemed to make it more fun for the both of them.

"I live to serve you, my Lord" she kissed him again "Do whatever you want to me"

And he did, over and over again, with a passion that left her bruised, sweaty, hoarse and exhausted. The princess was sure no one else in the palace had been able to get any sleep that night with how much Zuko had made her scream. It had been one of the best things she had ever experienced in her life.

The only thing that rivaled it was the feeling of his weight above her, his cock and cum still deep inside, as they both drifted off, satisfied and sure that no one else in the world could have ever hoped to make them this happy.

They were above everybody else - and thus perfect for each other.

Chapter Text

Zuko had fully expected to become a target once he left his nation to join the Avatar. Not only was his new group a threat to his father's reckless, cruel ambition, it'd be a personal slight against the man himself, and the young prince had already learned the hard way exactly how his father dealt with that sort of thing.

However, he had not assumed Azula would be too bothered. If anything, she should have been happy, right? She had never cared for him and he was the one thing standing between her and the throne. Surely whatever offense she'd take to him turning his back on their family would be eclipsed by what it meant for her ambition.

Instead, Azula spent three whole months constantly tracking him down and attacking him. Not his group, him. Even once her own friends seemed to finally have enough of all the evil their nation was doing, and of Azula herself, and thus joined them as well, Azula would act as if it anyone other than Zuko was merely colateral damage, as if it made no matter if they lived or died, as long as Zuko himself was punished, and he couldn't understand why. 

Not until Azula finally overpowered him and he was forced to go back home.

Zuko had assumed he'd be turned into a prisoner, and in a way he was. But as Azula had put it, a prince, even a disgraced one, deserved better than an ordinary cell.

He was taken to his sister's chambers, where he was chained and then put into a large, golden cage that resembled the ones made to move large beasts around. A the bottom of it lay a futon for him to sleep in. The cage's door also had a retangle cut into it, so Azula could slide him some food if she was feeling generous, which Zuko had assumed wouldn't be often.

Once again, he had been unbelievably mistaken, to an almost comical degree.

Azula made sure he ate well, got enough sleep, and would even have him be to the garden to get some sunlight or practice his bending every now and then, though obviously he'd be in chains during those moments, like an animal allowed to release all pent up energy while still kept on a somewhat short leash. His cell was also always perfectly clean, as were his clothes and Zuko himself. Eventually Azula even had the bottom of the cell changed, turning it into a bed of sorts, spacious, comfortable and with plenty of pillows and covers to keep him cozy and warm.

She truly had meant it when she said he'd no ordinary prisoner. She treated him more like a prized possession, or even a beloved pet.

Zuko had understood why pretty quickly. He had, however, refused to truly accept it for quite some time.

He managed to disregard her strange affection for him as genuine siince he witnessed first hand how she was being far more reckless than usual, skipping some meals, neglecting to practice her bending, and walking around looking a bit dishelved, make-up either smudged or completely absent, her messy hair fully down instead of perfectly in place with a top-knot. All things she would have never, ever done before.

Her changing clothes in front of him and even sleeping fully naked sometimes didn't seem as strange as it usually would have if Zuko wasn't also witnessing her cower in fear in front of people only she could see, then crying herself to sleep only to wake up screaming from some horrible nightmare. 

The vacant stares at the wall, at the ceiling, and even at Zuko himself sometimes, like she didn't even recognize him and he genuinely was just a pet or piece of furniture in her room, made it easy for him to convince himself that what he assumed were inappropriate, downright lustful gazes towards him must not have been what they seemed or, at the very least, were the result of his sister being mentally unwell to the point that she mistook him for someone else.

Azula snapped him out of that foolish denial after his first month as her beloved hostage, when whatever was left of her sanity, or shame, seemed to finally disappear.

She quietly opened the door to his cage in the middle of the night, getting inside of it and waking him up by pulling his sheets to the side, rubbing his cock over that fabric of his pants.

At first, Zuko froze. It took him some time to process the information that, yes, this was indeed happening, it wasn't yet another perverse dream brought on by the tons of inappropriate situations he had seen Azula in. His own sister, his mentally deranged, wicked, beautiful sister wanted him to be her lover.

"Stop" he pleaded, despite the way his whole body seemed to ache for more of her touch, to the point that even grabbing ahold of her wrist practically set him alight "You don't want this"

"Don't I?" she mocked as she climbed atop his lap, straddling him, and even with only the moon casting only light in the room, Zuko had been able to tell she was both offering him a devilish, confident smirk, yet still blushing like a shy little girl "How would you know? Did you learn to read minds while you were on your little adventures, Zuzu?"

"You're not well" he insisted, trying to push her away to create some distance between their bodies, but Azula would entangle her legs with his and her hands clung to his arms in a vice-like grip, trapping him in a strange embrace "Once you recover, you'll regret this"

"Only you could feel guilty over taking advantage of someone who's holding you captive" she laughed and tried to kiss him, but Zuko turned away. 

Of course, that did nothing to discourage her. She kissed his cheek, his chin and then his neck, awkwardly trying to overpower him so she could grind on his lap. Each time his cock would press up against her, Azula would smirk.

During the struggle, her robe started to slide off a bit, first exposing her shoulders, then a bit of her breasts. By the time Zuko had her pinned to the bottom of his cell, it wasn't covering anything, fully open, and Zuko froze at the sight of her pink, puffy nipples practically begging for attention, as well as her glistening, soaked cunt.

"Do you believe me now, dum-dum?" she asked, grabbing both of his hands and making him grope her breasts, before sliding one further down her body and between her legs.

Unable to hold back any further, Zuko gave him. He embraced and kissed her passionately, making her take off her robe and then undressing as well, the two of them shamelessly touching each other. Azula moaned and held him close as he sucked on her breasts, coverin them in hickeys and bite marks while pushing two fingers into her. She was so tight he could barely even move them at first.

Every little thing made her squirm, cry out and blush. It was obvious that he would be her first, much like she would be his. He would take his own sister's virginity. In a cage. A cage she had made so he could never, ever leave her.

It was a truly absurd situation and yet, somehow, when it happened, it had felt completely right.

When he first pushed his cock into her, he couldn't care less about the fact that he was still a prisoner, that they had been bitter rivals for years, and that he had always envied and resented her. When she moaned and sighed with each thurst, any thought of his honor, his friends, and the greater good was fully forgotten, as if none of it had ever crossed his mind at all.

When she wrapped her arms and legs around him, trying to keep him close even as he had to move back a bit to keep sliding in and out of her, his ambition for the throne and his dreams for a better country, a better world, seemed like foolish, childish delusions that simply could not compete with the reality of Azula's love, of feeling her trembling in his arms because of the pleasure he was giving her, the sensation of her nails digging into his back or of her teeth biting into his neck and shoulder, her sultry voice whispering sweet, dirty nothings in his ear, asking him to give it to her harder, faster, deeper.

And God help him, but the knowledge that they had the same blood, same father, same mother, same eyes, same hair, same features... not only did it not disgust him one bit, it only made him crave her more - to the point that he couldn't stop after that first time. He didn't pull out after filling her with his cum, keeping her pinned underneath him until his cock hardened once more, making love to her all night, making her come over and over again, giving her every drop of his seed until they were both too exhausted to move another muscle and finally fell asleep, still wrapped in each other, in a sweaty, bruised mess of entangled limbs.

He hadn't bothered to try to resist her any of the other nights in which she demaded some affection. Quite the contrary. 

Whenever she was being haunted by whatever ghosts her mind would force her to face, Zuko would try to gently goad her towards him, promising her that none of it was real, that it was just the two of them in that room. When she'd get inside the cage with him, he'd hold her close and continue to soothe her with his words until she either fell asleep or seeked further comfort through sex.

As she stopped skipping meals, fixed her looks and went back to dedicating herself to firebending, he rewarded her by letting her sit on his face so he could eat her out for as long as she liked.

Azula clearly appreciated his concern for her well-being, and, of course, the borderline insatiable lust. So much so that she would now lead him around the palace by his chains, so he could stay by her side as she went about her daily obligations. He would also be let out of his cage to share meals with her, and he honestly didn't even have to argue that much to get her to allow him to only sleep in it, not have to actually live in it, even if he was still never allowed out of the room unless Azula was with him.

She was also kind enough to make it up to him with a blowjob whenever her royal duties kept her busy for most of the day, causing her to not be able to give him as much attention as usual.

Having the princess herself suck my cock. Truly the luckiest prisoner in the history of the world, he would think to himself.

After two months of this strange love-affair, with summer's end only a few days away, Azula finally decided to give him her biggest show of affection just yet.

She opened the door to his cage, but didn't get inside. Instead, she offered him her hand and let him out, so he could share her bed - the same bed she had largely pretended didn't even exist since their first night together.

Her touches and kisses were still passionate, but far more sweet and tender, as they undressed each other slowly, and each embrace and longing look seemed to make Azula more vulnerable than the latter. Zuko couldn't recall ever seeing her so defenseless, earnest and open.

He carried her over to the bed gently, where she immediately allowed him to take his place between her legs. Each movement was slow and deep. Azula kept her eyes on his the entire time and her hands reached for his, their fingers entwining.

"Do I make you happy?" she asked, the insecurity in her voice genuinely breaking Zuko's heart - where had the cruel, cunning, selfish princess he had always known gone?

"You do. Happier than I've ever been" 

"Do you love me?"

"Yes. Always have"

As the tears slide down her face, Zuko kissed them away.

"Promise you never leave me again"

He did, and meant it. And maybe it was about the way he had been treating her those past two months, caring for her in his own way, or about the tenderness she showed her that night, but Azula seemed to believe it, to the point that her madness couldn't make her doubt it.

So much so that she didn't make him go back to the cage at any point after that night. And less than a week later, on the day of the comet, when his friends saved the world and forced their way past every guard in the palace to finally rescue him, Azula seemed completely at peace, and fully surrendered, not a trace of fear or sadness on her face.

She knew the new Fire Lord would be as kind to her as she had been to him.
