In hindsight, this was a bad idea.

Not the getting into a purely sexual relationship with the Avatar. Oh no, that was one of her best ideas. Of course, there was a difference between having regular sex, and this.

Azula flexed her wrists, testing the strength of the earth shackles through the red silk lining he had insisted upon.

"Comfortable?"

The Avatar was being sincere in his question. Azula felt like scowling, of course she's fine, but she settled for a sigh.

"The armor is colder without any clothing underneath."

He heated his hands, sliding them underneath her chest plate, casually rubbing his palms against her breasts. It was familiar territory for him. They had had so many exchanges that it was becoming domestic.

Once, they had had a particularly brutal exchange that started out as a spar and led to the Avatar wrapping his hands around her throat as he fucked her into the ground; but then, as she basked in the afterglow and recovered her breath for the next round, he had nuzzled her neck and asked how her day had went.

Azula had cut the exchange short and the Avatar still owed her two orgasms.

That was what led to her current predicament. She had told him to make it up to her, and he had blushed and stammered as he told her about this fantasy.

Azula had agreed to it then, but in hindsight she had given in too easily. She should have teased him about fantasizing about her armor of all things, or demanded an exchange, but he had looked so cute when he asked.

Azula looked back at the Avatar. He wasn't flustered now as he groped and jiggled her breasts.

"Avatar..." she said in a warning tone. Warning against what, she wasn't quite sure. All she knew was that she was uncomfortably bare aside from a few plates of metal across her upper body and lower legs.

"Princess," he replied in a voice that was far too smug. He trailed his fingers over her nipples before pinching them so the tips pressed against the cold metal inside of her armor.

"This is how I was dressed on the Day of the Black Sun," she stated, biting back a moan.

"Not quite," he said, blowing a gust of wind that tickled her bare stomach down to her nether regions.

Azula twisted in her restraints and glared at him. She could break them easily but she was hoping that the Avatar would, at the very least, disrobe.

"You're so impatient," he chuckled, kneading her breasts.

"You're a tease," she shot back and was just about to press against him and demand he hurry up when the Avatar leaned forward and started sucking on her bottom lip.

He was getting too fond of kissing her.

Azula gradually opened her mouth, allowing him to slip in and rake his tongue. She then allowed herself to be coaxed into his mouth where he gently sucked on her tongue for a full minute, before she pulled back and bit down hard.

Blood pooled on his bottom lip. "My, my, did I do that?" she asked as he recoiled.

He fingered the cut on his lip and looked at her with a hurt expression as though she had gravely wounded him a second time.

"I'm not your girlfriend," she muttered before leaning forward and lapping away at the blood.

He stepped forward, and Azula groaned appreciatively at the clothed heat pressing against her, before kissing the corner of his mouth and resting her head back against the wall. "Get on with it."

He stepped back and Azula tried to kick him, but he nimbly dodged.

"Avatar," she glared.

"Princess," he quipped, mimicking her tone before reaching down and freeing his cock.

You're forgiven.

She stared appreciatively as he twitched and grew harder under her stare. A pearl of precum glistened on his tip.

He stepped forward and the view disappeared although she felt him nudging against her thigh. She stopped craning her neck, and noted with surprise that he had removed his shirt.

He leaned forward slowly, as though awaiting permission, before capturing her lips in a sweet kiss.

Azula felt fabric behind her as he placed his folded shirt behind her head in a makeshift pillow. She broke the kiss. She was always the first to break the kiss, even on the rare occasions where she was the one to initiate them. The Avatar had a better set of lungs.

"What are you planning?" She murmured when he didn't immediately resume the kiss.

He trailed his hands downward, ghosting over her stomach and heat to grip her thighs.

"Can I shackle your legs?" He asked, and she nodded.

He spread her thighs apart and angled them till everything was on display.

If her father could see her now, thought Azula before quickly banishing the thought away. She wouldn't think of family during moments like this. Besides, her father lost his fight against the Avatar and if he expected her to do all the work in rescuing him then he could very well wait and allow her to feel some measure of release.

Azula pressed her lips together as earth formed over her ankles. She wanted the Avatar to be inside of her, but he had stepped back once again and was roaming his eyes across her body.

She felt her face flush. "Is this what you envisioned that day?" She said, keeping the shame out of her voice. "Was this the fantasy you created after I defeated you without my bending?"

His eyes lingered on her cunt. "No," he said slowly, "back then I was too preoccupied with not dying."

"You did die," she corrected and he finally looked up. "I killed you," she added when he didn't respond.

He reached out and lifted her chin, his fingers curling underneath. "You're adorable," he said.

If looks could kill the Avatar would be a corpse.

He ran his thumb across her jaw, correctly suspecting that if he brought the digit closer to her mouth, she'd bite it off.

"I've had this fantasy a couple of times," he admitted, before dropping down to his knees.

The Avatar looked good between her legs.

She admired the way his sharp eyes and sleek eyebrows contrasted against his broad nose and jaw, before she felt his thumbs spread her folds.

Azula frowned slightly, appraising him. "What's are you doing, Avatar?" She asked in the same warning tone she had used to instill fear in battle hardened soldiers over twice her age.

She felt his warm breath caress her core. "I'm admiring the view," he said, making an appreciative sound before moving to bite the inside of her thigh, his thumbs still spreading her open as he suckled the bite mark into a hickey.

He moved to her other thigh, his warm breath ghosting over her once again.

Azula could feel him smile into her thigh as he made a matching mark.

She closed her eyes and counted to ten. "How many times?" She asked, her breathing only slightly uneven.

"A couple of times. At night," he said, placing a kiss on her thigh, and then crossing over once again to place a kiss on the other one.

Azula gulped. She felt him move back to the center, his every breath sending a coil of heat running through her.

He loudly smacked his lips, the sound so obscene that Azula involuntary moved to press her legs together before remembering that they were tethered to the wall.

"May I, Princess?" He asked, as though she wasn't glistening with proof of her arousal.

"If you must."

A broad stroke of tongue resulted in her releasing a moan.

Enabled, he repeated the gesture, before furiously lapping at her clit.

Azula clenched her teeth together as he alternated between the broad and shallow strokes. It was one thing to have sex with the enemy, it was quite another thing to compliment them.

Of course, he would have proof of his prowess on his tongue. Azula felt herself grow wet with want and could hear the change as his licks echoed sloppily in the otherwise empty room.

She tried to clench around his tongue, making the Avatar pause. Azula couldn't stop the resulting groan of disappointment from escaping her.

She felt him smile against her, and Azula knew that if she looked down, she'd see him staring up at her with a smug look. She firmly closed her eyes.

She felt him purse his lips around her clit and suck.

Her mouth dropped open.

She felt him flick his tongue and thought of how she looked down there, swollen and dripping. His thumbs would lose their grip soon, trying to keep her spread open as she quivered and released another rush of liquid.

The Avatar hummed appreciatively, moving his mouth down and suckling her till she was, relatively, dry before placing soft kisses along her folds and plunging his tongue inside of her.

Do I taste that good? thought Azula, because the Avatar's tongue had to have been thoroughly soaked with her juices, and yet he rested it inside of her without refrain, moving back only as far as he needed to take a breath and slowly thrusting it back and forth inside of her.

"Filthy," she said, inflecting as much disdain as she could into her voice. "How dare you, ah, think of me this way."

He moaned and wiggled his tongue, sending waves of pleasure.

She didn't last long, spilling into him without preamble, but the Avatar didn't stop. He lapped at her through the orgasm, pressing a trail of kisses to her clit, before removing his thumbs to nibble and suck at her folds, and then spreading them once more as he sunk his tongue back in.

Belatedly, Azula realized that the high-pitched keening noise was coming from her.

"H-how— Who taught you how to do this?" she demanded, a mass of raw nerves throbbing between her legs.

The Avatar withdrew his tongue with a perverse slurp that sent a flush of heat racing across her face.

He stood up. There was a glistening string connecting his lips down to hers. He wiped it away, then casually brushed her entrance with his fingers.

"No one taught me," he said, rubbing a circle against her before slowly plunging two fingers inside and then, after a moment of consideration, adding a third. "But I've used my fingers on you loads of times and I figured it was similar."

Of course. He's a prodigy, thought Azula a bit hysterically as he started curling his fingers, stretching her tight walls, and seemingly intent on ignoring his own erection.

She took a haggard breath as he wiggled his fingers and started to slowly thrust them back and forth. "This is your fantasy?" she tried to sneer.

He spread his fingers, making her release a garbled moan, before rubbing them against a spot he was far too familiar with.

"Yeah," he whispered, staring at her, as he twisted his wrist and rubbed her clit with his thumb, coaxing her through a second orgasm.

She panted, and avoided his gaze; all too aware of how she must have looked, and sounded, like coming for him when tussled up like this, arched for him and shamelessly bared.

Azula wondered, not for the first time, when their relationship had blindly moved past a goal post and charted into a territory past "just sex" and into "you know my body better than anyone else."

The Avatar removed herself from these thoughts by removing his fingers, only to playfully send a gust of wind under her armor; one to tickle at her feet and another to coldly brush against her nipples.

"How long have you fantasized about me?" she asked, mentally congratulating herself for sounding unaffected.

"Longer than you think," he said, stepping forward, rubbing his cock against her, wetting it with her juices. He kissed at the underside of her boobs peeking out from beneath her armor, and then he pushed her thighs further back, and pressed his cock into her with one long thrust.

Azula groaned as she felt the familiar weight of his balls press against her. His cock was far less nimble than his fingers. But this position she was in, it was torture. She was unable to do anything.

The Avatar rubbed the hickeys he left on her thighs instead of hammering into her like she wanted. Azula sighed.

He was such a tease.

"Aang," she cooed, switching tactics. He had the nerve to look at her and smirk. "Do you want something, Princess?" He asked, reaching down to rub at her with his fingers.

Azula fumed. He slowly drew back his cock. "Do you want me to beg?" She snapped but it came out sounding like a plea.

The Avatar thought about it for a bit, or pretended to at least. His cock was rubbing against that spot of hers making it difficult for her to focus.

He removed his cock with a wet plop and proceeded to grind against her, before dragging the head of his cock across her clit and back against her entrance.

"I want you to purr for me, Kitten."

Azula snapped her back into focus with a glare. "I hate that pet name," she said, mustering as much hatred as she could into her voice.

Given her current position, and the fact that she was dealing with the Avatar, he remained frustratingly unaffected.

He plunged his cock back into her going, somehow, slower than before.

"Avatar..."

"Aang," he corrected, stopping just as his head brushed against that spot. "And just a small purr. C'mon. You know I like it slow."

She did, but she'd rather swallow coal than give in.

"I don't purr," she growled.

"That's it!" He beamed at her. "Good Kitten."

"I'm going to kill you," she said, but the threat was swallowed by her moans as he started to pound into her with enough force that the top of her head was brushing the shackles around her wrists with every thrust.

He came at the same time as her. A pity. She would have liked to watch him cum.

They rested for a bit, although Azula couldn't understand why the Avatar was exhausted. He only came once.

Azula felt him knead her ass as he remained soft inside of her. Tease.

She leaned her head back and closed her eyes, giving a pleasant hum as those hands reached upwards and started massaging her lower back.

"Kitten."

Scratch that. She was going to kill him.

Of course, given her current predicament, the lashing would have to be verbal.

"Aang—" she opened her eyes and the words died in her throat.

"Yes?"

She had forgotten just how damn attractive he was.

"Yes, Princess?" He amended, mistaking her shock for disapproval.

"How is it that no one else has seen you like this?" the words were not what she meant to say but given the way it made him turn red, Azula was glad she had said them. Red was such a pretty color on him.

He rubbed his neck. Azula could feel him twitch inside of her and grow semi hard. "I've only been with you. Physically," he said, flustered.

There were many things, many pleasant things Azula could have said in response, but she absolutely despised that pet name and wanted revenge.

"How embarrassing," she taunted.

He blinked stupidly at her. "You've been with others?" He half asked, half stated.

"Of course," lied Azula.

He removed his cock, and Azula was about to confess to the lie then and there, but then he asked, "How many?" And there was an edge to his voice.

Interesting.

"Since we started?" asked Azula, stalling for time. She felt his seed start to drip out of her but then he pushed the head of his cock back in, stoppering the cum.

Very interesting.

"Ten," she groaned, "but it could have been more. I never kept count."

"Keep count now," he demanded, moving away his cock and bringing his hand down on her a pussy in a blistering slap.

Azula jolted.

He kept his hand there. Staring at her. Waiting.

Azula bit her lip. That had hurt. One slap and she was throbbing with both pain and heat.

He gripped her.

"One," she said.

He looked at her, and Azula lost her breath.

"You don't have to count," he said gently, raising his hand. "I'm not going to stop."

Liar.

Azula grit her teeth as he brought his hand down over and over again in a series of stinging slaps before he realized he could slap her on the upstroke as well. The first upstroke shocked a gasp out of her and made him alternate his slaps. He would lay a stinging slap across her pussy and rub his palm with the juices before laying a blistering one on the next stroke, making her legs shake against the shackles as his slaps filled the room.

A strangled groan escaped her, when he paused to stroke her slit. There was blood in her mouth, she must have bit her lip, but Azula couldn't remember doing so. All she could focus on was the present and the burning coils of pain and pleasure throbbing through her pussy.

Damn this man.

He'd stop if she asked him too. She knew he was soft like that. Even though her core ached with the force of his slaps, she knew he paused after each one for her benefit; in case she wanted to say anything.

She fixed him a glare that had long lost its heat. He blew a stream of air that made quiver then he slowly and purposefully scooped up his seed that was dripping out of her, and pushed it back in with a thrust of his fingers.

She forgot herself. Shuddering, she tried to bring herself forward to ride his digits but the shackles prevented her from doing anything aside from embarrassing herself.

He rubbed his fingers against her walls, then slowly withdrew, and smeared the rest on her folds.

"You're so stubborn," he murmured, using one hand to lift her slightly at an angle before bringing the other one down.

She tensed, only to realize it was a bluff. She opened her eyes to see him staring at her with a half-lidded expression. He raised his hand to his face and, while maintaining eye contact, pressed a kiss to the center of his palm before bringing it down with more force than she thought possible.

She yelped, feeling pain explode across her center. He increased his pace. Matching her racing heartbeat. She tried to close her mouth, to recover her dignity, but he, without missing a beat, brought his hand down hard enough to bruise.

Eventually the roaring in her ears and the vibrations in her nether regions subsided.

"Water?"

She shook her head, blinking back tears. She felt him rub his cock against her, using it to once more scoop up his seed and gently nudge it back in.

"I didn't take you for the jealous type," she croaked, taking a moment to not so subtly catch her breath.

He waited patiently, but the look on his face made her shiver with anticipation. She knew that look. It was the one he made right before she made him climax into the Avatar state.

He trailed his fingers across her thighs, before slowly spreading her out her folds. The feeling of cold air against tender heated skin making her pussy flutter.

"Look at me," he asked, as though she could look away.

He pursed his lips, a large glob of spit appearing between them.

No.

He sucked it back into his mouth. Making a show of swishing his cheeks and gathering saliva. All while maintaining eye contact.

She said nothing.

A splat, and she shuddered, feeling his spit drip into her sore and aching pussy.

He dragged his cock up and down, mixing his spit with his seed. Then he adjusted himself, removing a hand to hold his cock and using the other hand, fingers and thumb, to spread her apart.

Azula yelped more from the shock and humiliation than the pain as he began slapping his cock against her clit.

He paused and began swiping his cock to the side. Lathering her with horizontal slaps.

Azula imagined that her pussy was as red and inflamed as her face.

He brought his cock down once more, and pressed until the head was kissing her entrance; then he pushed her thighs, fingernails digging into the hickeys, until they would spread no further.

"This is mine," he said, and Azula had only a second to note that there was something raw in those words before he was penetrating her much deeper than he had before.

"Aang," she gasped in frustration. It was all she could do to keep from squirming as he pressed himself so deep inside of her that she was sure his balls would leave imprints on her skin.

He made no effort to move, even as Azula squeezed and did her best to coax him otherwise.

Damn his resilience.

With great difficulty she held still, waiting to see what he would do.

He rested his forehead against hers and placed the palm of his hands against her lower stomach. "You're mine," he said softly, looking into her eyes, and then he pressed down.

That, whether it was his face, his voice, his hands, his cock, or all of the above, sent her over the edge. Azula moaned his name and felt him spill into her in the midst of her orgasm.

Afterwards, she hummed satisfactorily into his shoulder and waited for him to disengage but he didn't.

Azula felt him pinch marks into her thighs and sighed. There was a precipice between possessive and surly.

"I lied," she said, wincing at the hoarseness of her voice. "I haven't been with anyone, physically, besides you."

At a later time, Azula would reflect on the significance of that statement, but for now all she wanted was to wrap her arms around him and melt.

He removed the shackles and she did just that. Hard or soft, the Avatar fit so perfectly inside her that it was as though he was molded from marble with her specifications in mind.

She sighed happily as he nuzzled her neck.

"I have a room with a bath," he said, hedging the edge of her chest armor with his fingertips.

Azula paused. She let him remove the armor and felt the stickiness and soreness between her legs. "...considering this was all for your benefit," she said, daring him to challenge her words.

He slid the armor off her legs and chuckled into her shoulder before carrying her out of the room.

"You're far too good at this," she purred.
