Work Text:

This has to be Katara’s most stressful day of the month yet.

She loves being the Southern Water Tribe Ambassador—and she’ll never give up her position—but spirits can the job get stressful. She’s sat through three long meetings throughout the day, listening to Zuko’s advisors pick apart every tiny fucking detail of her treaties.

And to make it even better, there’s been a rumor circulating about Katara’s affair with Zuko. It’s true of course, but that doesn’t make it any easier to deal with. She can almost feel the hostile glares of Zuko’s multitude of suitors following her down every hallway of the palace.

It’s all so exhausting sometimes.

But those are all problems to worry about later. Right now, Katara finally has some time to herself and she’s planning on making the most of it. Her favorite new technique always seems to wash away the stress.

Katara feels proud of herself for the idea of it. The swampbenders’ manipulations of the vines always fascinated her; the way the water seemed to come to life was incredible. It had the ability to grab, to hold, to touch. On her own, Katara had experimented with moving water just like that. She learned to form long, slender tendrils of water, making them dance and wrap around her body as if they were solid objects.

It was only a matter of time before she discovered how pleasurable that sensation could be.

Like she has so many times before, Katara readies herself on her bed—completely nude—with a supply of water in easy reach on her bedside table. Gently swaying her hands, she draws forth multiple tendrils of water, pulling them slowly and steadily towards her in a well-practiced motion. Katara winds them around her body like watery serpents, wrapping them around her waist, her thighs, and her breasts.

She sighs and closes her eyes as she sinks into the pleasure of her element. Katara continues to move the water, squeezing and caressing her body until the throbbing heat between her legs becomes unbearable. Allowing one of the tendrils to wander lower, she rocks her hips as it brushes along her clit.

Katara moans at the sensation and pushes the water further down her body. Her patience is in short supply; she wants to be filled now.

The beginning of a tendril presses in and she gasps at the sensation. She sighs and rolls her hips as the water she controls trembles along with her body.

The first time she’d done this, Katara had barely been able to concentrate on the water as pleasure raced through her body. It has become easier to control with practice, much to her delight.

Katara ruts her hips up and down, sighing as the water penetrates her pussy in any shape she chooses. The warm heat of Zuko’s cock is far more enjoyable than the coolness of the water, but Katara loves the malleability of it, how she can make it twist and turn inside her.

She shudders again at the thought of her last time with Zuko. She had been in a very similar position to how she is now, knees spread across his waist as she rolled her hips down against him. Where is he when she needs him, anyway?

No sooner than the thought crosses Katara’s mind, the door to her bedroom abruptly opens and she’s met with that same golden stare she had been imagining. Memories of several be-careful-what-you-wish-for stories that had been instilled in Katara throughout her childhood come rushing back. She did want to see Zuko, but not like this—surrounded by thick tentacles of water wrapped around and inside her body.

Zuko simply stands completely frozen, staring at her in open-mouthed shock. Katara drops the water instantly and hurriedly covers herself with a blanket when she notices the open door.

Fuck—Zuko! Close the door!”

Her shrill voice seems to startle him into action. He scrambles to close and lock the door, nearly tripping over his own feet in the process. Katara notices Zuko’s cheeks have flushed bright red. That leaves the two of them, staring at each other in silence.

Zuko speaks up first, awkwardly clearing his throat. “I’m…uh…sorry—I really should have knocked.”

“Yeah,” Katara laughs nervously, her cheeks still hot with embarrassment. She can feel the water saturating the sheets beneath her, the evidence of her interrupted private time. “Sorry you walked in on…that.”

“Oh, I don’t mind!” Zuko says quickly, making Katara raise an eyebrow at him. “No I mean—it’s my fault. Completely my fault.”

Another pause. Katara isn’t sure what to say. Zuko scratches his neck nervously.

“So, um…what were you doing?” he asks.

Her cheeks are burning. How can Katara even explain this to him? She really had meant to tell Zuko about it eventually—but she didn’t ever imagine him finding out this way. How exactly can she tell him she likes filling her ass and pussy with her own bending without sounding like a total freak?

“Well…sometimes I like using my bending for…pleasure,” she says carefully as she averts her gaze. Zuko still looks confused. Katara covers her face with her hands. “Ugh, this is so embarrassing—”

“No, no—I’d just…never considered it before,” Zuko says, letting out a short chuckle before continuing. “Fire wouldn’t work that way at all, but water…it makes sense.”

Katara nods slowly, cautiously bringing her gaze back to his. “Yeah, it does.”

Zuko stares back at her as if he’s itching to ask more. Katara notices a faint hint of lust in his gaze and the deepening flush on his cheeks. Her stomach clenches in anticipation. She desperately hopes he’s in the mood, but unfortunately, his heavy robes leave far too much to the imagination.

Katara licks her lips, deciding to test her luck. “Would you…like me to show you?”

The spark of lust in Zuko’s gaze becomes a wildfire as he nods eagerly. Katara smirks, her insides pulsing in anticipation as the awkwardness of the situation evaporates. She slowly pulls back the sheets, first exposing her breasts, then the rest of her body, still dripping with the water she’d hastily dropped moments before.

Katara’s eyes never leave Zuko’s as she does it. She can see the hungry curiosity in his gaze. After her body is fully exposed, Zuko steps forward with an outstretched hand.

“Ah ah,” Katara scolds with a smirk, catching him before he can touch her. “You interrupted me, remember? It’s only fair that I get a chance to finish.”

Zuko pouts at that, but he does step back.

“Oh don’t worry. If you can behave yourself and not interrupt again, I’ll let you touch me, okay?” Katara purrs as she begins to pull up the discarded water from the sheets, her movements deliberate and seductive.

Zuko nods tightly as he steps back and sinks to his knees. Katara loves the desperation in his eyes as they trace over every inch of her exposed skin. Though she won’t admit it to Zuko right now, she’s also itching to touch him. She’ll have to make sure that it’s worth the wait.

With a gentle motion of her hands, she forms the water back into its octopus shape, winding it around her body once more. Katara takes her time as she moves each tendril at an agonizing pace. It makes Zuko practically drool, and Katara loves the way his eyes gleam with lust.

“It’s like having extra arms,” Katara explains alluringly. “So many options.”

To make her point, she wraps one tendril around her breasts and squeezes them gently with a sigh. Zuko’s fists clench against his thighs.

“Enjoying yourself so far?” Katara teases.

“I—Fuck yes, Katara.” Zuko’s voice is breathy and tight, as if there’s nothing he’d rather do than touch her right now.

It’s music to Katara’s ears. She imagines his cock swelling and straining against his robes, and suddenly she needs to see it for herself.

“Can you show me how much you’re enjoying yourself? Take off those robes,” she orders.

Zuko eagerly obeys. He strips off layer after layer as fast as his hands can move. Katara notices how hard he is and licks her lips.

“You really are loving this, aren’t you?” she purrs as she reaches out a small length of water to tease his thick cock as it bobs with his every movement.

Zuko grunts at the sensation. “Fuck, Katara, so good—why did you hide this from me?”

“Oh don’t worry. I’ll show you how good I can be.” Katara smirks at how worked up he already is. She’s barely even started and Zuko is already standing rigid, toes curling with the effort it takes to keep himself under control.

Deciding to further test his restraint, Katara moves the water between her legs, eyes never leaving Zuko’s as she begins to roll her hips. She spreads her knees wider, fully exposing herself to him. Katara is impressed at how still Zuko keeps himself. He makes no move towards her, only continues to stare with that heavy, lust-filled look in his eyes.

Katara lets out a breathy moan as she caresses herself in her most pleasurable places with expert technique.

“Sometimes” —she keens as the water touches her— “when you’re away, I pretend it’s you inside me. I shape it just like your nice, big cock.”

She squeezes his length with her water for emphasis, and Zuko looks like he’s about to explode. “Fuck, Katara—”

She smirks. “Do you want to touch me like this too?”

Yes—I do! Fuck yes, let me touch you,” he pleads without hesitation. Spirits, does she love it when he’s needy like this.

“How badly do you really want it?” Katara teases with another thrust of her hips.

So much, Katara, please,” Zuko begs. “I can make you feel so good, please just let me—”

“Are you sorry for interrupting?”

Yes, I’m so sorry, let me make it up to you. Please, Katara—”

Katara throws her head back and cums with a moan, thighs shaking as she feels the warm wetness gush from her. She stares into Zuko’s eyes as she does, and fuck does he look beautiful like that. Eyes desperate and focused on her, cheeks warm with a rosy blush, cock hard and already dripping. So eager to please.

“I think you’ve earned your turn now,” Katara sighs as she comes down. “You really can behave yourself sometimes. You really are my good boy, aren’t you?”

“Oh please, Katara, yes—I promise I’ll be good for you, so good—”

She cuts him off by untangling some of the water from her own body and reaching towards him with it. Zuko’s mouth clamps shut as he stares down at it in nervous awe. Katara almost laughs to herself. He’ll never be able to watch her practice bending with a straight face again.

Zuko yelps as Katara wraps a stream of water around his ass, giving it a tight squeeze. The embarrassed flush on his cheeks is priceless.

“Sorry,” she giggles. “I’ve always wanted to do that.”

Zuko just smiles at her and gently rolls his eyes. Katara takes the opportunity to wind another tendril around his back as she pulls him towards the bed. She guides him towards her lap until he’s flush against her, his hot breath caressing her neck. As their bodies finally meet, she sighs happily at the feeling of his warm skin against hers and his rock-hard cock pressing into her stomach. Fuck is she glad Zuko walked in on her today. She’s dreamed of doing this for so long.

With a teasing smile, Katara guides one of his hands to rest against her still-full stomach, nearly moaning at the feeling of his soft, warm palm. “Do you feel how full I am?”

She shifts the water inside her, and Zuko groans against her. “Fuck, Katara. That’s so fucking hot.”

“I’m glad you think so,” she murmurs into his ear. With a smirk, she strokes her hand down his toned abdomen, rubbing gently around his navel. “Do you want me to fill you too?”

Fuck, Katara, I…” he groans, settling his hands around her waist and stroking her belly with his thumbs.

Clearly, he’s considering it, fascinated by the movement of the water under her skin. She strokes a hand down his back reassuringly.

“It doesn’t hurt, I promise,” she whispers. “I’ll make you feel so good.”

There’s a hint of reluctance in his eyes, but Katara recognizes the desire there. She waves her hands and draws two tendrils of water up his sides. They wind around him slowly, lapping at his nipples and gently squeezing his body. Katara watches him softly moan and writhe against the pressure, and she can’t believe how lucky she is.

“Does this feel good?” she asks.

Yes, Katara—so good,” he groans. “Please—”

“Do you want more?” she asks as she leisurely strokes the water along his body.

She feels Zuko’s fingers clench harder against her waist. “Yes.”

“You’re going to have to be more specific,” Katara whispers against his neck before pressing a light kiss to his fluttering pulse. “Tell me what you want.”

“Make me feel good, Katara,” he says breathlessly. “Fill me up, just like you. Please.

Hearing him speak the words makes her body burn with arousal. Katara wastes no time in circling the tendrils of water tighter around Zuko’s back. She rolls them carefully, shifting him onto the bed beneath her. Zuko eagerly allows the water to guide him onto his back. As he relaxes into his position, he stares up at her, flushed and breathless. Katara feels a fresh wave of arousal burn between her legs at the sight.

She kisses his stomach before shifting the water again. “Of course, my love. I’ll fill you so well.”

Katara traces the water down Zuko’s legs until she reaches his knees, gently pulling them apart. The tendril laps gently at his ass before carefully pressing into his entrance. Zuko gasps, his back arching as his hands fist in the sheets.

Keeping the water steady with one hand, Katara soothingly rubs Zuko’s hip with the other. “Still doing okay?”

Great, Katara,” he whines, rolling his hips. “Please—keep going.”

Allowing him a moment to adjust, Katara eagerly follows his request. She continues the flow of water into Zuko’s ass as she winds it carefully inside him. She knows that there’s a spot that will make him writhe, and she intends to find it.

He whines in response to the sensation, and Katara can see precum dripping onto his toned stomach from his hard cock. The way he closes his eyes and tips his head back lets Katara know that he’s aching for more.

Holding him in place with her water, Katara answers Zuko’s silent request. She fills him slowly and gently, searching for any signs of distress. But none come; there's only the rosy flush of his cheeks and the soft pants sending faint sparks flickering down his chest. Katara feels her underside pulsing at the sight. He looks so fucking sexy that it makes her mouth water.

Katara shifts the water still inside her at the sight, Zuko writhing in sheer ecstasy beneath her. The knowledge that he feels just as deliciously full as she does only makes her pussy drip even more. Struggling to control her bending, Katara shifts the streams wrapped around Zuko’s knees, pulling them further apart to give her a better view.

Holding him spread just for her, Katara pumps the stream of water harder, fucking in and out of his body in earnest. She moans in delight as she watches the movement of her element inside him, swelling his belly and shifting in ways that make him gasp and writhe in pleasure. She can’t help herself; she reaches down with one hand and strokes his abdomen in time with her thrusts, moaning at the feeling of the subtle bulge under her fingertips.

Zuko opens his eyes to look up at her. Between groans and heavy breaths, she hears him mumble, “Katara…”

“What is it?” Katara asks, reaching out a hand to stroke his cheek softly. “It feels good, doesn’t it?”

Her hand wanders south, stroking softly over Zuko’s chest and midsection. Katara continues shifting the water. She can feel it moving inside of him, pressing up towards her through his smooth skin. Zuko just groans and grips the sheets tighter. Katara smirks and holds firm, admiring the ripple of his muscles as he convulses in pleasure.

“You just love this, don’t you?” Katara purrs as she cups his belly with both hands. Zuko moans as she presses down slightly. “I know, it feels so good to get fucked like this. Do you like feeling nice and full, just like me?”

He moans again, the smooth muscles of his abdomen rippling as he shudders in pleasure. “Katara…please—

Leaning down, she cuts him off with a kiss. “What do you need, baby?”

“Need—ah—want to touch you,” he whines, raising his hands towards her breasts, awaiting her permission.

Katara grabs Zuko’s wrists and pulls his hands against her. His strong thumbs rub against her nipples in slow circles and she moans at the attention.

“How do you want to touch me?” she asks as she teasingly shifts the water inside him, leaning into his touch. “Tell me everything you’d like to do to me, my lord.”

Zuko’s eyes light up at the name she knows he loves, taking a deep breath as the water continues to fuck and fill him. “I—mm—I’ll fuck you so good, Katara. My lady. Let me taste you and fuck your pretty pussy. I want to fuck you until you cum all over me.”

Katara smirks, the rambling words pouring from him making her ache for his touch all the more. “My my, what a naughty mouth you have tonight, Fire Lord. Can you show me just how naughty it can be?”

Fuck yes, Katara,” he breathes, and she’s already crawling on top of him.

She eases the water out of her own body before settling down on Zuko’s face, moaning the moment she feels his warm tongue desperately reach out for her. She loves sitting on her throne, as Zuko loves to tease.

Katara takes a moment to adjust, gasping in delight as she grinds her dripping pussy against Zuko’s chin and his eager mouth. She stares down at his flushed body as he begins to lick and suck in earnest, admiring the view. His knees are still spread wide with carefully-placed tendrils of water, and his hard cock bobs against his stomach as his hips shake from Katara’s relentless thrusts. Tracing her hands along his torso, Katara admires the tautness of his muscles, the subtle bulge in his belly.

“Do you want more?” she croons as she rubs slow circles along Zuko’s stomach. “I can fill you as much as you’d like.”

Mm-hmm!” she feels Zuko grunt against her pussy. She keens as she feels his voice vibrate up her spine.

His hands reach around her hips and pull her even closer against his face. Katara feels herself quiver at his expert touch. It feels almost like a challenge, and she’s eager to accept it.

With a wave of one hand, she eases the thick tendril of water further inside Zuko’s body. She twists and turns it as it enters him, caressing the sensitive walls. Zuko’s whines and moans massage her clit along with his lips, and Katara encourages every one.

“Your mouth feels so good, love,” she moans.

One of her hands continues to relentlessly tease his body with the water, while the other rests on his belly. Katara can feel the thrusting motions under his warm, toned skin and grinds herself even harder against Zuko’s face, relishing in the erotic sight before her.

Her finger brushes something wet, and Katara’s eyes are drawn to Zuko’s hard cock, already dribbling precum. Though he can’t see her face, she smirks, tracing a finger down the side. Zuko groans.

“You’re just about to cum and I’ve barely even touched you,” Katara purrs as she grips the hard flesh and rubs it with her thumb. “Such a good, patient boy. I think you deserve to cum.”

Zuko mumbles what Katara assumes to be pleas underneath her. She moans appreciatively, rolling her hips as his desperate voice rumbles against her clit.

“You—ahh—like that, baby? Want me to—mm—play with your pretty cock until you cum all over yourself?” Katara feels her voice grow increasingly needy under his ministrations.

The groan that sounds vaguely like a ‘please’ is all the encouragement she needs. Katara pumps Zuko’s shaft faster in a tantalizing rhythm with the tendril of water buried in his ass. She watches with pleasure as more thick, white fluid begins to leak from his cock. Lust burns even brighter within Katara as she watches the evidence of his arousal drip from him. An idea suddenly occurs to her, and Katara almost giggles in mischievous delight.

She positions her hand over Zuko’s cock and reaches out with her bending. With a small amount of coaxing, a few beads of precum trickle down his shaft. Katara grins triumphantly. How had she never thought to try this before?

With another careful motion of her hand, Katara sends a small spurt of cum splattering across Zuko’s stomach. He jerks and whines beneath her in response, hands trembling against her hips.

“Did you like that, my lord?” Katara teases. She reaches her hand back between his legs, tenderly massaging his balls between her fingers. “I can make sure you cum now. I’ll milk every last drop from that pretty, thick cock of yours.”

Katara rides Zuko's face, teasing him with water tentacles and bending his cum.

And Katara does just that. She releases Zuko’s balls and bends his cum once more, slowly drawing it out of him as he writhes and begs against her. Katara paints it across his stomach and chest, watching as it trickles over his toned muscles and his faintly distended belly. It glistens in the candlelight, and the contours of his body ripple as he continues the hungry movements of his tongue.

Zuko’s teeth scrape against her clit once more, and it’s more than Katara can handle. She throws back her head and calls out Zuko’s name, her body shaking as she reaches her peak. She swears she nearly sees stars.

As she comes down, Katara climbs off of Zuko’s face with a sigh and turns to admire her handiwork.

She’s grateful for the change of scenery—he’s a sight to behold. His hair is rumpled and messy, sticking to his flushed cheeks and fanning out against the pillow behind him. His lips still glisten with her arousal, and Katara practically drools when he licks his lips, taking in every last bit of her cum within his reach. Despite the warm glow of her orgasm still surrounding her, Katara feels herself ache for more.

Judging from Zuko’s still-erect cock, he must be aching for her too.

“I guess I still need to take care of this,” Katara says, gently stroking him with a finger. “You did say you wanted to fuck me, didn’t you?”

Mm—yes, Katara,” Zuko groans, tense and breathless against the water still tormenting him. “Wanna fuck your pussy, Katara. I’ll make you cum again, cum all over my cock.”

“You’re very convincing this evening, my lord.” Biting her lip, Katara positions herself over his cock, careful to keep the water steadily lapping at his ass. “You’re going to have to work pretty hard to make me cum, you know. I don’t know how long you can last with my pussy around your cock and my water inside you.”

“I guess we’ll see,” he purrs playfully, accepting her challenge.

Zuko reaches for her hips as his eyes light up with lust. Katara sinks down onto his length, allowing his eager hands to pull her against him. His warm cock enters her easily; she’s already so wet from his earlier efforts. A desperate noise escapes her as she feels him fill and stretch her. So much better than using water on her own.

Desperate to fulfill his promise, Zuko begins to thrust his hips up into Katara as much as he’s able from his position on his back. She responds eagerly, rolling her hips down to meet his in quick motions. Looking back to Zuko’s face, Katara catches a hint of a smirk in his expression.

“Still think you can make me cum first, do you?” Katara taunts.

Zuko playfully narrows his eyes as smirk tugs at his lips. “Of course I can. I know how much you love riding my cock.”

“Careful, that sounds like a challenge.”

With that, Katara thrusts the water in quicker motions, watching his cum-streaked belly twitch with it. Zuko sees it too; his eyes are fixed on her hands hovering above him and she swears she hears him whimper.

“Want me to show you a little trick?” Katara says, lowering her hands to his stomach.

She gently rubs her fingers into him before flattening her palms against his skin. It’s the same technique she uses to heal; she focuses on the water inside Zuko, enchanting it with her energy. He gasps and arches his back when she does. Katara smirks. She knows exactly how good that feels.

“I use it all the time to stop the cramping,” she explains as she uses one hand to rub circles around his navel for emphasis. “It feels so good, doesn’t it?”

Fuck—Katara—”

“I really don’t think you’re going to win this. Do you?” she purrs. Her hands continue to caress his body, groping and massaging him from his hard nipples to his full belly.

Even with his eyes practically rolled back, Zuko grits out, “Yes.”

Their movements turn frenzied as their competition escalates. Zuko’s hands are firm against Katara’s hips, holding her tight as he fucks up into her as quickly as he can, positioning his hips to reach all the perfect places. Katara focuses on the water, pumping it in and out of Zuko’s body, twisting and turning to torment the bundle of nerves that makes him whine and squirm.

Finally, Katara can’t hold herself back any longer. Zuko’s heaving chest, his half-lidded eyes, his deliciously warm cock rutting inside her—it’s too much to handle. She gushes all over Zuko’s hips—just as he’d promised she would—and she feels him shake under her as she does.

Zuko’s thrusts become erratic and he moans in the way Katara knows as him reaching his climax, but she doesn’t feel the hot fluid spurt inside her. He gives a few last thrusts before she feels his cock wilt, and Katara’s eyes widen at the realization. He’s so empty from her teasing that there’s nothing left inside him.

Katara sighs and rolls off of Zuko, flopping down on the sheets next to him. She carefully bends the water out of his body and discards it. Zuko groans as she does, equally exhausted and spent.

“I think that was a tie?” he jokes.

Katara laughs, curling into his side. “Sure, we’ll call that a tie.”

She rests her head on Zuko’s shoulder, peering up at his relaxed, candle-lit face. He looks just as peaceful and content as she feels.

“You know, I wouldn’t mind at all if you interrupted me again,” Katara mumbles.

Zuko’s eyes shift to meet hers. “I’ll make sure to interrupt you whenever I can.”

Katara kisses his cheek and wraps her arms tighter around his body. She’s so glad to have spent tonight with Zuko instead of by herself. From his heavy-lidded eyes, she can tell he intends to sleep here, too. How lucky she is to have a boyfriend who forgets to knock.

“Well, I guess I’ll have to hold you to that.”

Well, hope you all enjoyed!
