Chapter Text
When Zuko regained consciousness, he knew three things.
First, the droplets of water streaking down his arms were as glacial as the ice ceiling he was suspended from. His wrists were tightly bound and his feet were just barely touching the floor, forcing his chest forward.
Second, he had failed to capture the avatar. That stupid bald air bender had caught him off-guard just as Zuko was making preparations to raid the village he was supposedly taking refuge in. The wind was punched from Zuko’s lungs as his body was slammed into the lake. He’d struggled to resurface, but found himself trapped in an inescapable whirlpool, dragging him down into the dark freezing depths until he blacked out.
And third, he was going to wipe that smirk of Sokka’s face the second he had a chance.
The inexplicably shirtless alpha from the water tribe lounged against an icy wall, arms crossed, studying the disgraced prince. It was cold enough that each of his breaths created small clouds of mist and his nipples were peaked, but there was no way someone who’d ever fought Zuko would be dumb enough to build a fire.
The corner of his lips twitched. “Look who’s finally up.”
Zuko blew a strand of long dark hair from his face. He glanced up to find his hands had been chained and hung from a hook drilled into the solid ice above him. Forcing himself to remain expressionless, he lowered his gaze to Sokka. “What do you want?
“What do I want?” Sokka snorted. “Your father has declared that your sister Azula is his only heir before he died and she announced your exile was permanent, so I want to know why you’re still trying to kidnap Aang. You really think turning him over to the Fire Nation will change anything after all this time?”
The sides of Zuko’s nose wrinkled the way a dog’s might before a growl, except he kept his teeth hidden. “That is none of your concern.”
Sokka raised an eyebrow. “Not my concern? You are trying to kidnap the Avatar. Sounds like it’s everyone’s concern.”
Amber eyes narrowed on the water tribe alpha. “I dishonored my father, my king, and was given a chance to regain that honor.”
“Oh, please,” Sokka rolled his eyes, dragging himself off the wall he was leaning against. “I’m pretty sure that ship sailed about two decades ago. Sounds more like the desperate obsession of a sad, lonely alpha.”
“Shut up!” Zuko snarled, thrashing against his bindings and hissing in pain as his shoulder was wrenched out of its socket. “You know nothing about me!”
“I know you’ve been nothing but a giant pain all of these years.” Sokka took a step forward, gesturing to Zuko’s scar. “Just like I know your father gave you that. Not exactly an honorable guy, was he?”
“I said, shut up!” Zuko kicked out, his foot connecting with the center of Sokka’s chest, sending him flying backwards.
The water tribe alpha hit the wall with an oof. He sprang to his feet, glaring at Zuko. “You know, I was gonna play nice and try to talk some sense into you, but to be honest, I’m sick of your shit.”
The sharp wave of angry alpha pheromones rolling off him stung Zuko’s nose. “Kill me then, because I’ll never stop. One day, I will bring the avatar back to the Fire Nation.”
“Kill you?” Sokka grabbed him, fingers digging into the soft flesh of his hips. Heat radiated from his bare chest like an industrial Fire Nation furnace. “Now why would I do that?”
“Get your hands off me,” Zuko growled, hackles rising. He tried to kick out again, but Sokka was too fast, pinning the fire alpha’s legs between his own.
Leaning in, Sokka nipped the skin where Zuko’s neck met his shoulder, just over the mating gland. “Behave. I’m not above killing you if it comes to that, but it would interfere with my plans for you.”
Zuko twisted and snapped his teeth, just barely missing Sukko’s ear. “I don’t care about your plans.”
The tip of Sukko’s canine dug into Zuko’s neck, not hard enough to piercing the gland, but enough to make the struggling alpha freeze.
“You wouldn’t dare,” he spat.
Tongue replaced tooth and Sokka sucked hard, leaving a violent purple mark blooming on Zuko’s neck. “Oh, I dare.” He drew back, grinning into the other alpha’s furious gaze. “Just not yet.”
Reaching up, he tucked a long strand of black hair behind Zuko’s ear. “I’m gonna bitch you, and when you are desperate and begging, then I’ll mark you.”
Another wave of pheromones hit Zuko’s nose, but this time his eyes widened. He’d been too focused on himself to realize, but it was obvious now. The water alpha’s pupils were dilated, his scent was sharpening with arousal, and there was a very obviously bulge in his pants.
Sokka was in rut…
… which meant Zuko was, quite literally, fucked.
“No,” he rasped out, fighting against the chains that bound him to the roof. “You can’t.”
Sokka’s low chuckle held an edge. “I think you’ll find there’s a lot of things I can do.”
He let go of Zuko’s hips, and pulled a knife from the sheathe at his side. It slid under Zuko’s belt, and the long piece of cloth fluttered to the ground.
Zuko’s jaw tightened. “You could have just untied it.”
Sokka shrugged. “Yeah. I could have.”
He pulled open the dark maroon and gold trimmed robe then slipped a hand below Zuko’s shirt. Running his fingers over the well-honed muscles of the fire bender’s abdomen, then chest, Sokka let out a low, appreciative whistle. “You never stopped training, even after all these years.”
“Why would I?” Zuko gritted out, refusing to acknowledge the part of him that wanted so badly to lean into the alpha’s touch, if only for warmth. “Once I capture the avatar, I will be going home and I need to be ready to-”
“Home?” Sokka interrupted, lightly twisting the fire bender’s nipple between his fingers. “Your home is with me now.”
“No, it’s not!” Zuko snarled, jerking as the fingers playing with his nipple twisted it painfully. “My home is- stop that!”
Sokka’s steady gaze held his. “Yes, it is and no, I won’t. You do understand how bitching works, right?”
“Of course I do.” Above his head, Zuko’s nails dug into the palm of his hands. “And it requires the alpha getting bitched to want the change.”
The ghost a smile played across Sokka’s lips. “You say that like it’s a problem.”
Zuko refused to look away. “It is, because I am not willing.”
Sokka’s hand slipped back out from beneath Zuko’s shirt, only to finger the waistband of the fire bender’s pants. “You will be.”
He tugged the fabric down over Zuko’s ass, then his thighs, and let go. It slid off, revealing muscular legs.
Sokka glanced down, then back up at Zuko with an amused expression. “No underclothes?”
For the first time, Zuko turned his head. His face burned with rage and humiliation. “Don’t take it to mean something it doesn’t.”
The knife slid up under his shirt, slicing it open. “You’re saying I shouldn’t take it as a sign that you were secretly hoping to get caught?” Sokka ran his hand down the length of Zuko’s exposed torso, noting the way the other alpha shivered at his touch, but didn’t recoil. “That you weren’t drooling at the idea of being fucked?”
“Or maybe you should take it as a sign I didn’t expect to be forced to be your rut partner,” Zuko snapped. He felt a thumb brush over his hip bone and jerked back, then scoffed. “Aren’t you supposed to be this big hero? The greatest warrior the water tribe has ever seen? Wouldn’t think you’d have trouble finding a willing partner if that were true.”
“It is true.” There wasn’t even the faintest hint of anger in his voice. Nothing to indicate Zuko was getting under his skin. Sokka undid his own pants, stepping out of them as they pooled around his ankles, and pressed his body flush against Zuko’s nakedness. “This isn’t just about finding a rut partner though.”
There was nowhere for Zuko to retreat to- not that he would, because that would mean submitting, something his alpha pride would never allow him to do.
“Then what’s it about?” he growled. The thundering of his pulse was deafening as he felt something hot and hard grind against his hip.
“You…” Sokka paused, tilting his head to nip at the deep purple bruise he’d left on Zuko’s neck. “…and me.”
His hand wrapped around the fire bender’s soft cock, tracing a circle around the flushed tip with his thumb. “You are being a nuisance… and I’m sick of dealing with your shit.”
Zuko sucked in a breath, writhing helplessly against the touch. “Too bad.”
“You are the world’s unhappiest alpha…” Sokka continued, brushing his soft lips over Zuko’s, testing. “…and yet, for some reason, my alpha has decided that you’re my mate.” When the fire alpha didn’t bite him, Sokka kissed him firmer this time. “My omega.”
“You’re crazy.” Zuko’s low rasp sounded strained. “And I’m not your mate. I’m an alpha.”
“For now.”
Reaching up, he unhooked the chains binding the fire bender’s wrists from the roof. Zuko tumbled forwards as blood rushed agonizingly back into his limbs.
Sokka caught him with a grin. “So eager already.”
“Am not!” Zuko yanked himself out of the other alpha’s arms, only to trip backwards over a stone. He hit the ground, hard, flat on his back
Before he had a chance to sit up, Sokka was on top of him, nudging his legs apart with a knee. He leaned in with a grin, and nipped the tip of Zuko’s nose. “Are too.”
Zuko lunged, aiming to wrap the chains that bound him around Sokka’s neck, but his vision blurred as the world spun. He blinked as his stomach hit the cold ground and his hips were yanked up.
Like an omega presenting to their alpha.
Zuko whirled, hooking his leg around Sokka’s waist and yanking him off-balance. The other alpha let out a surprised sound, but Zuko was already on his feet, eyes darting to find the entrance of the cave. It was so dark, he could hardly see anything-
A hand squeezed the nape of his neck, and Zuko snarled, instinctively fighting the scruffing. He was an alpha, a prince, and a fire bender! Sokka was a powerless nobody from the Southern Water Tribe. He was clearly the inferior one, but yet, he dared to put hands on Zuko!
It was no use.
His knees grew weak, then gave out. His mind was a tornado of fury as he fell forward onto the ground. “You…”
“I didn’t want to have to resort to this, but you let me no choice,” Sokka scolded. “If you run off now, you could get hurt.”
“And if I stay, I’m going to get bitched,” Zuko shot back, pinned by the hand still squeezing his neck.
Sokka raised an eyebrow. “So you are willing.”
There was nothing Zuko could say to that. Shame burned through his body. How could he have allowed another alpha to establish dominance over him?
The hand pinning him down eased its pressure, but Zuko offered no fight. He’d already be caught in an act of surrender and his limbs felt too heavy to move. His hips were gripped and pulled back up into the presentation position omegas assumed when they wanted to be mounted by their alphas. His ass was squeezed then slapped lightly. “Yo, Zuko, you still with me?”
“Stop talking and get on with it already before I die of old age,” he growled, cheeks burning as red as the scar his father bestowed. “Since apparently you intend to hold me hostage until then.”
The challenge in his voice hit home. Sokka’s nostrils flared as he lost the shred of control he’d been clinging to and with a single stroke, he buried himself inside the Fire Nation’s exiled prince.
Zuko moaned at the strange sensation of being filled as his alpha raged in his mind. Danger! Fight! Do not moan! Roar! Challenge him! Get him off! Make him bare his throat!
“You’re so tight,” Sokka groaned as he thrust deeper. “You’re going to have to relax if you want to enjoy this.”
“What makes you think,” Zuko grunted, shifting his weight, “that I’m going to enjoy this?”
One of the hands gripping his hip slid forward to stroke Zuko’s half-hard cock. A finger flicked over his tip, gathering a bead of pre-cum.
Sokka held it up where Zuko could see. “This seems like fairly strong evidence to me.”
He drove forward, bottoming out inside the gasping fire bender. Then, slower, he rocked his hips, pressing against the curve of Zuko’s ass, letting the heat of their skin meld together.
“What? No scathing reply?” Sokka murmured, skimming a hand down over Zuko’s ribs towards his ass and firmly squeezing. “I have to say, I didn’t expect you to submit so easily.”
“I’m not submitting!” Zuko clawed at the icy floor, scrabbling to find purchase, but discovering none. The ice burned his bare chest as he slid over it and his knees had gone numb from cold. His nipples were hardened from the subzero temperatures of the cave and the ice he was being fucked on.
He let out a pained groan as the large cock slammed into him again and again. He’d never been mounted before, received no prep-not that he would he allowed such a thing to ever occur because that would mean he wanted this- and Sokka was thick, stretching him in unimaginable ways.
His own traitorous cock was fully hard, swollen from being stroked. That was all it was, just a physical response to an… external — he’d almost thought the world ‘pleasurable’, but corrected himself just in time — stimuli.
The fingers gripping his hips dug in. There was no way he wasn’t getting ten little bruises from this. “Relax,” Sokka growled. “Or this is going to hurt.”
His knot was starting to swell as he neared his climax. It was bumping into the tight ring of muscle, catching on Zuko’s rim.
“What is-” Zuko’s eyes widened and he made to move. “No, you can’t!”
Sokka pressed down on his lower back. “I said, relax.”
The alpha command in his voice, combined with the heaviness from the earlier scruffing, was too much for Zuko. He knew he should resist or fight, but his body obeyed. The tension in his muscles evaporated, his body going limp and pliant.
“That’s it...” The hand on his back moved in small, comforting circles. “Good boy.”
Part of Zuko wanted to lash out, to shout that he was not a boy, he was a man, an alpha, but that was the moment Sokka’s knot popped inside and then nothing else mattered.
This was wrong. All wrong.
Alphas didn’t take knots. They were the ones who knotted others.
Wrong, wrong, wrong…
His mouth fell open in a silent scream as he came. It should have hurt, being speared open and stretched to his limit, but instead, there was only this primal ecstasy exploding in his core. His own knot popped in the air, hot cum spurting onto the floor below, freezing obscenely on the ice.
Sokka’s hips jerked violently, then he stiffened. His cock pulsed, flooding Zuko with heat.
Wrong, wrong, wrong…
Alphas don’t submit. Alpha’s don’t get knotted. Alpha’s don’t get filled with cum.
It was wrong!
But if it were truly wrong, a small voice in the back of Zuko’s hazy mind whispered, then why did feel so damn good?
