Chapter Text
Zuko was not, by and large, a lucky man. And sure, it was disappointing to have your hopes and dreams crushed repeatedly, but over time, you got used to it. You learned to pretend you never even had hopes and dreams in the first place, that there was nothing you secretly wished for in the dead of night. This was, for the most part, effective. But he’d been failing miserably lately.
First, he’d hoped that his father would accept him when he returned home. Dream crushed. He knew now it had always been futile- a part of him had always known that, though he refused to admit it to himself.
When that dream had died for good, he turned to hoping that the Avatar and his friends would accept him. Dream dented, but eventually achieved. They had even gone back and smoothed out the dents they’d left in it, so surely any tiny bit of luck he did have had already been all used up by that.
But he had another secret hope. One he pretended didn’t exist, even to himself. One that he knew could never, ever, ever be. He had absolutely ruined any chance of achieving it himself before he’d even fully realized his true feelings, and now it was too late. It had to be too late.
Except, maybe it wasn’t. Because last week, during a healing session in which he’d acted utterly abominably, things had taken a turn. Katara had kissed him, held him, told him he was good. Katara had ridden him like her life depended on it, and he was still at a complete loss as to how exactly the whole situation had come about.
At first, he was convinced it was a dream. It was the only logical explanation. Yes, Katara was nice to him now- a dream in and of itself- but she would never see him like that. There were so many reasons- the way he’d treated her in the past, his family, his face. So when he awoke with the image of her beneath him, flushed and panting from her orgasm and spattered in his cum, he was sure it was just a beautiful, ephemeral dream that could never be reality.
It was, perhaps, a bit disturbing that his perverted mind could come up with such a clear image- exact in every detail, right down to the perfection of her dusky nipples, the dark mole low on her breast- but not all that surprising. After all, he’d had plenty of practice daydreaming about her since Ba Sing Se. If he was being completely honest with himself, his subconscious had been supplying him with image after unbidden image of her ever since he'd found her with that water-bending scroll.
His imaginings were so prolific that even when he found his cum-stained shirt, he'd assumed that he’d just relieved himself in the dead of night. Mortifyingly, it wouldn’t have been the first time. That was one of the reasons he always insisted on doing all his own laundry when he and Katara split up the chores.
It wasn’t until Katara had slyly winked at him over breakfast that he realized it had been real. He’d choked on his mango juice then, causing a scene as Toph whacked him hard on the back and demanded to know what had just scared him so much. He still wasn’t sure exactly what he’d managed to stammer out, but Toph apparently found it acceptable- though she was clearly suspicious. Katara had found it hilarious, if her giggling was any indication. The whole thing was beyond embarrassing.
That had been nearly a week ago. Zuko continued following Katara around like a lost little turtle-duck, doing anything she asked- or anything he thought she might ask- in hopes of earning another one of her angelic smiles, to soak up some of the sunshine she strew everywhere she went. Unfortunately they hadn’t had much alone time- a few moments here and there, usually doing chores around the beach house. By the time Zuko plucked up the courage to say anything to her, someone was always barging in.
He still didn’t understand how the unbelievably incredible situation had come about. It was baffling. He was convinced that it had to have been a mistake, but Katara was always winking at him now, peering up at him through those dark eyelashes, stretching her plump, kissable lips into a sweet smile.
And now.
Now, Katara was on her knees in front of him, her warm breath ghosting over his hard cock. His lips still tingled with her kisses, and he wildly thought back to how he had gotten into this situation. And how he could try to replicate it again in the future.
He’d been in the laundry room in the servants’ quarters, standing at the large table beside the wash tubs, drying and folding as usual. And then Katara had followed him in and closed the door, and given him that gorgeous, suggestive smirk that she was so good at.
“Thank you for helping out so much, Zuko.” The thanks sounded genuine, but there was a soft purr in her tone that lit sparks in his blood. “It’s really such a help.” She traipsed over to him, stopping just a few inches beside him, easily within reach.
“Of course.” He’d murmured, putting the tunic he’d just folded in Aang’s pile and turning to smile softly at her. “I’m happy to do it.”
Something softened in her eyes then, and Katara bit her lower lip. When she released it, that now familiar sparkle was back in her eye, and she was smirking up at him.
“If I remember correctly, I believe that I’d promised you something if you helped out like a good boy.” She reminded him, her smirk widening to a grin when the pet name sent shivers through him. Katara’s eyes flashed as they met his, and she splayed a hand across his chest, leaning up on her toes to ghost her lips against his before brushing her lips over his cheek, her lips tickling his ear.
“What do you say, Zuko?” She murmured. “Do you want me to suck your cock?”
A groan rumbled in Zuko’s chest, and he collected Katara up in his arms, capturing her lips in a deep kiss. He pulled her flush against him, rolling his hips into her so she would be sure to feel his growing need pressed hard against her abdomen.
“Spirits, yes.”
He felt her smile against her lips, and a moment later she was pulling back from him. Before she could sink to her knees though, Zuko had a brief moment of clarity, and caught her by her upper arms.
“Wait, Katara. I’m not- I wasn’t just helping you so that you would- you don’t owe me anything. I’m just trying to pull my own weight.” He told her earnestly, searching her gaze for any hesitation and finding none. Instead, Katara broke out into a brilliant smile, and gave his forearms a quick squeeze.
“I know, Zuko.” She assured him, leaning forwards to press another chaste kiss to his lips. “But I want to do this.” His grip had gone slack with shock at the statement- and the fact that all of his blood was busy rushing south- and Katara took advantage of that to slip out of his hold, and onto her knees in front of him.
Grinning up at him, Katara made quick work of his trousers, dropping them to the floor to pool around his ankles. His underclothes quickly followed, and the devilish smirk that played at Katara’s lips as she looked up at him through her dark lashes nearly killed him.
“Mmm look at you.” She purred, trailing her fingers down the length of him in a way that sent shivers through his entire body. When she reached the base of his cock, she wrapped her nimble fingers around him, and kissed him low on his stomach, just above the base of his cock. It wasn’t quite where he wanted her, but close enough that he had to catch the counter behind him in a white-knuckled grip to keep himself upright.
Unable to take his eyes off of her, Zuko watched, jaw slack, as Katara stuck out her tongue, licking a hot stripe from his root to his tip.
“There’s so much of you.” She hummed, giving him a thoughtful stroke. “I wonder if I’ll even be able to take all of you in my mouth.” She caught his gaze then, and kissed his leaking tip. When she pulled away, a bright spot of cum marked her red lips, and Zuko thought he might have died and gone to the spirit world.
Not breaking their gaze, Katara ran her lips down his cock, smearing his cum against his skin. About halfway down, she stuck her tongue out again, the wet rasp dragging against him in the most tantalizing way. She followed the trail of her tongue with her hand, stroking him with a maddeningly light touch. She licked up the other side of him before wrapping her lips around his head and sucking, her tongue flicking out against him.
Zuko groaned loudly, pleasure shooting through his veins. He gripped the counter behind him so tightly, he wouldn’t be surprised if it cracked.
“You taste so good, Zuko.” Katara murmured, lapping at his tip again. “So good.”
Zuko was far past being able to form words, and only managed a low grunt in response. Katara just smiled, and opened her mouth again, wrapping her lips around his cock and bobbing her head down. She didn’t get very far- more of his cock was out of her mouth than in it- but the feeling was indescribable. The moan that escaped Zuko’s throat was almost choked, and he had to bite his lower lip hard to keep from embarrassing himself and cumming already. The sight of Katara on her knees before him, red lips wrapped around him, was just too much, and Zuko had to shut his eyes tight. He lost himself in the pure mind-numbing pleasure of her mouth around him, warm and wet and perfect. She was a bit clumsy, but the sum of her attentions was unlike anything Zuko had ever experienced before.
He had no idea how long she’d been going- it simultaneously felt like she’d just started, and she’d been going forever- when he could hold out no longer, the tightening in his balls too strong to keep ignoring. Opening his eyes, Zuko was greeted with the unreal view of Katara, eyes closed as though in reverence as she worshiped his cock.
He memorized the image in an instant.
“Fuck I- Katara, I’m gonna-” He managed to choke out, forcibly uncurling one of his hands from the countertop to push at her shoulders, unable to form the words to properly tell her that he was about to cum.
Instead of popping off his dick like he expected, Katara opened her deep blue eyes, meeting his gaze through her lashes with a determined look. She shook her head slightly, then bobbed her head down, taking him deeper than she had before. Zuko felt his cock hit the back of Katara’s throat and immediately lost it, gripping her shoulder tightly and cursing as pleasure flooded his every nerve, nearly blinding him with its force. He came into Katara’s mouth, and groaned even louder when he felt her swallow around his cock, her mouth working him in a jaw-droppingly incredible way. His hips thrust forward without his permission, and Katara made a small noise when the movement forced him deeper still into her mouth, but she stayed resolutely where she was, swallowing him down as wave after wave of hot cum spurted out of him.
Finally spent, Zuko leaned heavily back against the counter behind him, panting hard as he tried to steady his racing heart. Katara drew back slowly, giving his softening cock a final gentle suck that drew a low groan out of him. He watched through dazed eyes as Katara got to her feet before him, carefully wiping an escaped drip of his cum from her lip and licking it off of her finger.
“Yum.” She purred, giving him a beatific grin.
“Spirits Katara.” He breathed back, sure he was just the victim of an overactive imagination. There was no way that that had really happened.
He let his eyes dance over her, taking in all the signs that she really had just gotten on her knees for him and sucked him off. Her lips were swollen, and her cheeks were flushed, and- his eyes fell on her shoulder, where her top was rumpled from his grip, and he winced, reaching out to smooth it out. He hadn’t meant to hold her so tightly, and he certainly hadn’t meant to thrust into her mouth.
“I'm sorry.” He apologized. “I didn’t mean to-”
“Don’t be sorry.” She interrupted, catching his hand in hers and squeezing it. “That was just what I wanted.”
She can’t be real. As if to prove to himself that she was, Zuko reached out and pulled her to him again, kissing her hard. She fit so perfectly against him, and holding her just felt so right. Zuko silently cursed himself for not doing this after the last time they’d been together. But he’d been so nervous last time, so sure that one wrong move would make her realize what a mistake she'd made, and she would push him away and slip through his fingers forever. But with this second time… it seemed like even if it was just a lapse in judgment on her part, it was a lasting one.
When he released her, Katara was giving him a curious, almost surprised look, but it quickly dissolved into her bright smile. She leaned up to give him a final peck, then grinned at him.
“Come on, we should go back to the main house. People will be hungry soon, and it’ll only be a matter of time before they’re looking for us.” She moved as though to leave, but Zuko unconsciously tightened his grip on her, holding her in place.
“Wait, but- what about- you didn’t-” Now spent, his words failed him at first, but Katara clearly wasn’t picking up what he was hinting at.
“You didn’t get to cum.” He managed, his cheeks burning.
Katara’s eyes went wide with surprise again, like she hadn’t expected him to say that. Like she thought he just expected a blowjob with nothing in return. After a moment though, she smiled, winking saucily up at him.
“There’s time for that later.” She smiled wolfishly at him. “Can I come to your room tonight?”
“Absolutely.” Zuko was nodding eagerly almost before the words crossed her lips.
“Perfect.” She slipped out of his grasp, shooting him a wink. “Later then.”
With that, she flitted towards the door as though nothing had happened, as though she hadn’t just shaken his entire world for the second time in a week. Katara paused at the threshold, giving Zuko a once-over, an appreciative look in her eyes.
“You might want to pull up your pants before you come out here.” She giggled. Flushing deeper, Zuko scrambled to cover himself, hardly even realizing that he’d forgotten- and hardly realizing that the promise of later had already sent blood rushing to his cock.
She really was going to be the death of him.
