Zuko and Sokka's field trip to the Boiling Rock goes awry as Zuko is discovered and captured, left chained in a cramped cell. All he wanted was Sokka's trust and to redeem himself. When Sokka breaks into his cell in the middle of the night, Zuko expects to be broken out, but Sokka has other ideas in the interest of delicious, steamy payback for everything Zuko has done.
Zuko really, really hoped Sokka knew what he was doing.
As they trudged up the steep volcanic cliff, the air was thick with both the steam from the lake and the lingering awkwardness that had permeated their partnership since embarking on this trip. Zuko was painfully aware of every movement he made, every word he said, nervous that Sokka would sense something there to mistrust, turning on him and leaving him here on this rock in the middle of nowhere. He wanted to prove himself more than anything, and, if he was being totally honest, Sokka intimidated the hell out of him. He seemed so cool, so sure of himself, the glue that held everyone together. Zuko figured that if he firmly won Sokka's approval, he would be in. But he hadn't thought that quest to prove himself would land him in a high security prison, showing his traitorous face among his own kind. But Zuko understood how badly Sokka wanted to regain his honour and find his father. Hell, he was the expert on obsessing over honour.
Sokka glanced over at him with his cool blue eyes, shocking Zuko out of his thoughts. Was he being observed? Zuko's lungs burned with the uphill climb, he could feel his skin breaking out in sweat. Still, he tried to give Sokka a weakly reassuring smile.
"He'd better be here," Sokka's voice was only slightly louder than the environment around them, like he was saying it mostly to himself.
Well, this plan had taken a sharp left turn. Zuko had been discovered, and he sat now in chains alone in a dark cell hardly bigger than a closet. At least Sokka still had a chance of escape, of finding his dad.
Suddenly, he heard a scuffle on the other side of the metal door. Zuko heard a loud thump against the door and he jumped. What was going on?
"Hello?" Zuko called. Whatever was happening, it couldn't be good.
The door creaked open, exposing Zuko's eyes to light so bright he needed a moment to adjust. Before he could, the door slammed shut again.
"Zuko?"
"Sokka!" Zuko strained against his cuffs. Had the other boy really fought those guards outside for him?
Sokka crossed the small room to him a fiddled with the chains, of course to no avail.
"I'm sorry, Sokka, you have to escape without me."
"Don't say that," Sokka's brow furrowed as he continued to mess with Zuko's chains. Despite the situation, Zuko smiled softly. He had won Sokka's trust after all, it only cost him the small price of his freedom.
"It's alright-" Zuko began.
"No, it isn't. You're crazy if you think I'm gonna leave you here after everything you've done for me. Now, think, how do we get you out of here?" Sokka paused and rose back to his full height, stroking his chin. Zuko smirked.
"I don't think there's anything we can do until the next guard rotation. You'll have to threaten them to give you the keys or something."
Sokka sighed, and to Zuko's surprise, Sokka kneeled in front of him. He met Zuko's eyes with a wary expression, making Zuko's heart leap. Sokka's expression was unreadable, like he was debating with himself. Was this another test somehow? Was he wrong about Sokka's feelings toward him? Did he resent Zuko for getting caught?
"Look, you really don't need to-" Zuko began.
Sokka lunged forward and pressed his palms to Zuko's cheeks, smashing his lips to Zuko's. Zuko gasped, frozen in utter shock. Sokka only pressed on like the warrior he was, sliding his hands down Zuko's chest. He couldn't believe this, what had gotten into Sokka? It took only moments for Zuko to move past his surprise and kiss him back, straining against his chains for an entirely different reason.
Sokka unexpectedly pulled away, leaving Zuko breathless and flushed.
"You think I didn't notice you staring at me on the war balloon? The way your eyes kept wandering down…" Sokka pressed a palm to Zuko's groin. He choked, witlessly arching his back in response.
"I…" he started, at a loss, "I didn't think you felt the same. What about Suki?"
Their faces were inches apart. Zuko could smell the familiar scent of salty ocean breeze and cherry wood that permeated Sokka, making him almost glad that he was chained to the chair. Otherwise, his knees would have buckled. Of course Zuko had been ogling Sokka the whole time, he wasn't only concerned about gaining the other man's trust, he had been hopelessly lusting over him. That lust had only gotten stronger when Sokka had reunited with his long lost fling, Suki. He hadn't known if he'd wanted Sokka to himself, or if he wanted both of them at the same time. The thought had filled him with shame, and now that he knew Sokka had sensed it, embarrassment.
Sokka gave him a knowing grin, the mischief that suited him so well sparkled in his bright blue eyes that seemed to shine in the dark, "Suki's not here. Do you see her? I don't." He made a show of swinging his head left and right, pretending to search for the girl.
Zuko strained against his chains to kiss Sokka again, desperate to satiate the urge that had plagued him for years. Sokka complied, undoubtedly knowing he held all the power. Was this the reason he broke into Zuko's cell? Sokka opened his mouth, letting the fire prince explore his mouth with his tongue. Zuko bucked, rubbing his hardening member against Sokka's chest like a cat in heat. He felt Sokka smirk against his mouth, making Zuko feel simultaneous rage and longing.
"I think I'll take these off now." Sokka tugged at Zuko's trousers, effortlessly pulling them until they were around Zuko's ankles. Zuko was beyond words, now whimpering as his unleashed length felt the open air and the other man's body heat. So close. Sokka's eyes widened, his gaze taking Zuko in.
"Fuck," Sokka mumbled, running one long finger from the tip all the way down. Zuko groaned, legs straightening in utter need, "you're so fucking big."
"What do you want?" Zuko managed. Sokka only shot him another shit-eating grin, causing Zuko to grit his teeth. He had the feeling he was being played with, something Sokka apparently had a reputation for, Suki had confided in him a night prior. He'd bedded many women over the course of his travels, and each would say the same thing. Sokka was an incurable tease who delighted in making his partner writhe and beg. Zuko wasn't sure whether he should dig in his heels and resist, or allow himself to play Sokka's game.
"What is it…" Sokka finally answered, wrapping a large, calloused hand around Zuko, "... that you want, prisoner?"
Zuko licked his swollen lips. He wanted to fuck Sokka so mercilessly that the entire prison could hear the screams of pleasure echoing. He wanted every single person on the Boiling Rock to hear Zuko dominate this cheeky, arrogant prick who had, up until fairly recently, been his sworn enemy.
"I want you to sit on it," Zuko settled for instead, sending a matching smirk to the other man. Sokka looked surprised before grinning, seemingly pleased by the challenge.
"Oh yeah?"
Sokka wrapped his lips around Zuko's length without warning, and Zuko cried out, not prepared for the hot, slick warmth of the other man's mouth. He sucked intensely, holding nothing back now. He moved his head back and forth and Zuko made all sorts of animalistic sounds, straining so hard against his restraints that he knew he'd have lasting bruises on his wrists and ankled. All Zuko could feel was the orgasm already building deep in his abdomen.
"Sokka, f-fuck," Zuko murmured, itching to grab the back of Sokka's head and slam it into his pelvis, submerging himself entirely in the other boy's throat. How satisfying it would be to hear Sokka choke on it, allowing someone else to have control for once. Zuko was the damn fire prince, for god sake, he was just the man for the job.
Sokka's tongue swirled around Zuko's shaft as he took him in deeper, deeper, until Zuko could feel the back of Sokka's throat. His cries were getting horse.
"Fuck yeah," Sokka slid off of Zuko to murmur, his own voice thick. He then continued to take Zuko in his mouth, bobbing his head faster, faster.
"If you keep going, I'm gonna…" Zuko trailed off as his eyes rolled back in his head. It was too late to warn Sokka before Zuko exploded in his mouth, twitching mercilessly as he unloaded wave after wave down the man's throat. Sokka only sucked harder, stretching out Zuko's orgasm to the point where Zuko could see nothing but stars. He felt lightheaded with ecstasy.
Sokka's mouth remained on Zuko as he moaned loud, allowing Zuko to notice he had been finishing himself off the entire time. Sokka erupted onto the stone floor of the cell, shuddering between Zuko's knees.
Sokka finally slid his mouth free, wiping his mouth on his dark red sleeve and smirking up at Zuko.
"I liked taking you as prisoner," he said, earning a weary glare from the still-trapped Zuko, "that was your payback for being a jerk all these years."
Sokka reached into his back pocket and retrieved a large ring of keys. Zuko's eyes popped out of his head as Sokka shook the keys in the air proudly. He'd seriously had those the whole time?
"Now, lets get you out of here."
