Chapter 2: The Lie Between Them
The rumbling faded, leaving only the hum of the crystals and the sound of their breath, harsh and uneven in the silence.
Zuko’s grip on her loosened, but he didn’t let go. His head was tilted, listening. The warrior in him was assessing, calculating. But the man, the one with her taste still on his tongue and her scent all over him, was still thrumming with a different kind of energy.
Katara pushed away from his chest, her movements clumsy. She fumbled with the tie of her trousers, her fingers trembling too badly to secure it. Shame was a cold flood, washing over the lingering waves of heat. She couldn’t look at him. She stared at the glowing vein in the floor, seeing Aang’s face, his trusting gray eyes.
“That was a mistake,” she whispered, her voice raw.
Zuko said nothing. He watched her struggle with the tie for a moment before his hand, large and steady, batted hers away. He did it up himself, his knuckles brushing the sensitive skin of her lower belly. She flinched.
“It happened,” he said flatly. His own need was a painful, throbbing ache he was ignoring. “Regret doesn’t change it.”
“I hate you,” she said, but the words were hollow, stripped of their earlier fire.
“You came for me,” he countered, his voice low and factual. “You screamed for me. Hate had nothing to do with that part.”
She finally looked up at him, her blue eyes bright with unshed tears and simmering fury. “You took advantage.”
A short, humorless laugh escaped him. “I didn’t hear you saying no. I felt you saying yes. Loud and clear.” He took a step closer, drawn back into her orbit despite the danger, despite everything. “You’re still saying it. You’re shaking with it.”
He was right. A fine, relentless tremor ran through her. It was anger, yes, and shame, but underneath it was the aftershock of a pleasure so profound it had rewritten her nerves. Her body was a traitor, craving a repeat of the annihilation.
He saw the conflict, the war within her, and it was the most captivating thing he’d ever witnessed. The righteous Katara, unraveled. He wanted to see more. He needed to see her come apart again, to prove the first time wasn’t a fluke, to brand it into her so deeply she’d never forget who owned that part of her.
The distant sound was forgotten.
He closed the gap between them, his hand coming up to cup her cheek. She stiffened, but didn’t pull away. Her eyes were huge, waiting.
“Tell me you didn’t feel it,” he murmured, his thumb tracing her bottom lip, still swollen from his kisses. “Tell me it meant nothing, and I’ll stop. I’ll sit in that corner and we can wait for whatever that noise was to kill us. But you have to say it. And you have to mean it.”
Katara’s lips parted. The denial was right there. It meant nothing. I felt nothing. The words clogged in her throat, thick and untrue. She remembered the shocking fullness of his fingers, the searing contact of his palm, the way her world had narrowed to a single, blinding point of pleasure. She saw the knowing glint in his amber eyes. He could smell the lie before she could utter it.
A broken sound, half-sob, half-sigh, escaped her. It was surrender.
His mouth was on hers again, instantly, a desperate collision. This time, there was no pretense of anger, no fuel of argument. It was pure, hungry need. They devoured each other. His tongue plunged deep, claiming her mouth with a rhythm that was already familiar, already addictive. She met him with equal fervor, her hands flying up to claw at his shoulders, then into his hair, pulling him closer as if she could merge their bodies through the clothes.
He walked her back until her shoulders met the crystal, the coolness a shock against her heated skin. One hand slid down her side, over the curve of her hip, and dipped between her thighs. He palmed her through the loosened fabric, a rough, possessive grope, and felt the soaked heat there. She moaned into his mouth, her hips jerking forward.
He broke the kiss, breathing heavily. “Tell me.”
“I’ve never…” she gasped, her forehead resting against his. “Never felt anything like that. Ever.”
He smirked, a slow, arrogant curl of his lips. “Of course you haven’t.” His hand moved, fingers rubbing her insistently through the cloth, and she whimpered. “You’ve always been so good. The perfect daughter. The perfect friend. The Avatar’s perfect, pure little hope.” He leaned in, his lips brushing her ear. “Never doing a single thing to disappoint anyone.”
His words were arrows, each one hitting its mark.
His words were arrows, each one hitting its mark. “Shut up,” she whispered, but her voice lacked conviction, muffled as he began kissing a hot, wet trail down her neck. He licked the salt from her skin, his teeth grazing her collarbone. She tipped her head back, offering more.
“Look at you,” he murmured against her pounding pulse. “Getting ruined by the Fire Nation prince. And you love it.” His mouth moved lower, over the fabric covering her sternum, towards the pronounced swell of her breasts. Her breath hitched, anticipation coiling tight in her belly. He didn’t fully expose her, just pressed his open mouth against the cloth where her nipple strained, the damp heat searing through.
Then he pulled back, his eyes dark with intent. He guided her backwards, away from the column, until his legs met a low, smooth outcropping of rock. He sat down with a grunt, spreading his thick thighs, and before she could process it, his hands were on her hips, pulling her down into his lap. She straddled him, her knees sinking into the soft moss on either side of his hips. The new position was shockingly intimate, her full weight settling onto him.
His arms locked around her, one hand splayed against the small of her back, the other gripping the voluptuous curve of her ass. He pulled her flush against him and captured her mouth again. This kiss was deeper, slower, more controlling than the frantic ones before. His tongue explored hers with a lazy arrogance that made her whimper. She could feel him, the hard, daunting length of him straining against his trousers, pressed exactly where she was already throbbing and embarrassingly wet.
“You feel that?” he breathed into her mouth, rolling his hips up once. A sharp, electrifying friction shot through her. She gasped, her nails digging into the shoulders of his tunic. “That’s what you’re saving for. But not today.”
He stilled her, his grip firm. “Today, this is enough. I can make you come again just like this. Look at you, already soaking through two layers of cloth for me.” He guided her hips with his hands on her ass, setting a slow, grinding rhythm. “Like this. Move with me.”
Katara, in a daze of pure sensation, obeyed. She rocked against him, the rough texture of his clothes providing a maddening, perfect pressure right on her clit. Each forward slide of her hips sent a jolt of pleasure so intense her vision blurred. She was moaning openly now, little broken sounds against his lips, lost in the primal simplicity of the motion.
“I’ll be the one to fuck you,” he promised, his voice low and ragged next to her ear. His own control was fraying; she could feel the tremble in his thighs beneath her, the rigid tension in his arms. “But I’m going to take my sweet time. I’m going to unravel you piece by piece until you forget any other touch.”
The cognitive dissonance should have shattered her. She was dry-humping the Crown Prince of the Fire Nation in a tomb. Aang, somewhere above or beyond these walls, believed she was pure, believed she was his. The thought of his devastated, confused face should have stopped her cold. Instead, it sent a forbidden, corrosive thrill through her veins, and she ground down on Zuko harder, seeking more.
“You’re so bad,” Zuko groaned, his forehead dropping to her shoulder. He was spurring her on, his hands clutching her ass, encouraging her pace. “Such a traitor. My perfect little traitor.” Each filthy affirmation stoked the fire in her core. She was close, so close, the coil winding impossibly tight.
Her movements became frantic, less guided, more desperate. She was chasing it, using him, her mind blank to everything but the building pressure and his relentless words. “That’s it,” he urged, his breath hot on her neck. “Take it. Come for me again. Show me how much you love betraying him.”
The orgasm ripped through her with a sudden, violent intensity. It wasn’t the shattering detonation of before, but a deep, rolling quake that clenched her entire body. A choked, guttural cry tore from her throat as she pressed herself down onto him, shuddering through wave after wave of raw sensation, the fabric between them soaked.
She collapsed against his chest, boneless and spent, her face buried in the hollow of his neck. He held her there, his own body rigid with unspent tension, his breathing harsh in her ear. He turned his head just enough to brush his lips against her temple. “Told you,” he whispered, the words thick with smug, agonized satisfaction.
Another rumble echoed through the catacombs, closer this time. A shower of fine crystal dust rained down from the ceiling, glittering in the bioluminescent light. It was followed by the distinct, scuffing sound of a footfall.
Then a voice, echoing with worried relief, called out from the darkness of a tunnel entrance. “Katara? Are you in here? I felt a seismic disturbance!”
It was Aang.
Katara froze, the blood turning to ice in her veins. Her head snapped up, her wide, guilty eyes meeting Zuko’s. He didn’t look panicked. A slow, dangerous smirk spread across his face as he carefully, deliberately, lifted her off his lap and set her on her wobbling legs. He stood up in one fluid motion, placing himself slightly in front of her, a shield and a claim all at once.
“Better fix your clothes, sweetheart,” Zuko said, his voice low enough for only her to hear. He didn’t look at her as he called out, his tone shifting to one of cool authority. “In here, Avatar. We’re both here.”
The voice that echoed back was tight with a concern that sliced through Katara harder than any blade.
"Katara? Are you okay?"
It was Sokka. Not just Aang.
Her brother’s voice acted like a bucket of glacial meltwater. She scrambled back, her fingers finally managing to knot the tie of her trousers with frantic, clumsy jerks. She swiped a hand across her swollen mouth, as if she could erase the feel of Zuko’s lips, the taste of him. The evidence was inside her, though, a phantom fullness and a slick, humming warmth that refused to cool.
“I’m here,” she called, her voice cracking. She cleared her throat, forcing strength into it. “I’m fine.”
Zuko watched her compose herself with an infuriating calm. He adjusted his own tunic, the movement casual, but his eyes never left the tunnel entrance where two figures materialized in the gloom. Aang emerged first, his usual air of gentle worry sharpened into palpable fear. Sokka was a half-step behind, boomerang drawn, his eyes scanning the cavern for threats and landing immediately, with a jolt of confusion, on the Fire Prince.
“Zuko?” Aang blurted, his body instinctively shifting into a defensive stance. “What are you—how did you get in here?”
“The same way you did, probably.” Zuko’s reply was flat, his hands held slightly away from his body in a gesture of non-aggression that felt like a mockery. “Through a door. Then it sealed.”
Sokka’s gaze darted between Zuko and his sister. He saw the flush high on her cheeks, the wildness in her usually composed eyes, the way her braid was coming partially undone. “Katara, what’s going on?” he demanded, stepping forward. “Did he hurt you?”
The question hung in the humming air.
Katara felt the lie form, smooth and necessary. “No. He didn’t. We were just… both trapped.” She couldn’t look at Aang. She focused on her brother, anchoring herself to his familiar, worried face. “The Dai Li took me. They must have captured him, too.”
Aang’s eyes softened with relief, but a sliver of something else—suspicion, or just hurt—flickered as he looked at Zuko. “Okay. Okay, good. We’ve been looking for you for hours. The city is… it’s falling apart. Azula’s here.”
Zuko’s head snapped up at his sister’s name, all his focus shifting. “Where?”
“Everywhere,” Sokka said grimly, finally lowering his boomerang but not putting it away. “She’s taken control of the Dai Li. There’s a coup. The Earth King is missing. We need to get out, now.”
“The walls are compromised,” Aang added, his voice urgent. “Toph feels shifts all through the lower levels. This whole place could come down.”
Another low groan reverberated through the stone, deeper and longer than before. A crack, thin and bright as a lightning fork, snaked up a distant crystal column with a sound like tearing silk.
The decision was made for them. Survival trumped everything—betrayal, shame, unresolved war.
“Move,” Zuko commanded, and it was Katara who flinched at the familiar tone of authority. He was already moving towards a different tunnel, one opposite the entrance Aang and Sokka had used. “This way. The air’s moving here. There’s a draft.”
He didn’t wait for consensus. He just strode into the dark, assuming they would follow.
And they did. Sokka grabbed Katara’s arm, pulling her along. Aang brought up the rear, his gaze lingering on her back for a moment too long before another shudder in the earth forced him to turn.
They ran through a labyrinth of glowing blue stone, the catacombs now feeling less like a tomb and more like the throat of a dying beast. Dust and shards of crystal fell around them. Zuko led with a terrifying certainty, his firebender’s sense for heat and airflow guiding him through the maze.
Katara ran, her body protesting. The pleasant ache between her thighs was now a jarring reminder with every step. The memory of his hands on her hips, his voice in her ear, was a film over her vision. She could still smell him on her skin, underneath the dust.
They burst into a larger chamber where a fissure had torn open the ceiling, revealing a sliver of smoky Ba Sing Se sky. The rubble formed a crude ramp.
“Up!” Sokka yelled.
They scrambled. Zuko went first, leaping onto a ledge and turning, his hand shooting out not for Katara, but for Aang, hauling the lighter Avatar up beside him. The contact was brief, impersonal. Then Aang turned and extended his glider staff for Sokka and Katara.
In moments, they were out, gulping in the hazy, chaotic air of the upper city. The sounds of distant conflict and collapsing masonry replaced the eerie hum. They were in a ruined garden, the walls around them scarred by recent firebending.
The four of them stood there, panting, a fractured and impossible group.
Zuko’s eyes found Katara’s across the short distance. His gaze was unreadable—a mask of princely detachment, but beneath it simmered the shared, secret truth of what had happened deep underground. He gave the slightest, almost imperceptible nod.
Then he turned away. “Azula’s that way,” he said, pointing towards plumes of black smoke coiling into the sky. “I have to find her.”
He didn’t say goodbye. He just left, melting into the chaos of the stricken city without a backward glance, leaving the three of them standing together.
Katara wrapped her arms around herself. Sokka slung an arm over her shoulders. “You’re sure you’re okay?” he whispered.
She nodded, mute.
Aang came close, his gray eyes searching hers. “He really didn’t try anything?”
The full weight of her guilt finally crashed down, acidic and choking. She made herself hold his gaze, the gaze of the boy—the man—who loved her, who she was supposed to love. She saw the lingering doubt in them, the fear that something had shifted.
She reached out and took his hand, squeezing it. Her skin felt filthy.
“No, Aang,” she said, her voice the steadiest it had been since the cave. “He didn’t.”
The smell of damp earth and singed canvas filled her nostrils. Katara sat on her bedroll in the small tent, her hands trembling in her lap. Outside, the sounds of their makeshift camp were soft: the low murmur of Sokka and Toph talking strategy, the crackle of the fire. Aang’s quiet, rhythmic breathing came from the tent next door.
He was sleeping. He was alive.
Azula’s lightning had been a searing white fork aimed at her heart. Zuko had moved then, a blur of red and black, his own fire deflecting the blow just enough. It had grazed Aang’s side instead of piercing his chest. A scorch mark on his ribs, not a hole in his heart. Zuko had saved his life.
Then he’d turned and fought Azula with a viciousness Katara had never seen, their duel a storm of blue and orange flame that lit up the cavern. She’d pulled Aang to safety, her healing water already glowing in her hands, her eyes stealing glances at the two royals trying to kill each other. Had she seen Zuko look at her, just once, amidst the fire? She couldn’t remember. The memory was all chaos and terror and the feel of Aang’s skin knitting back together under her fingers.
Now, in the silence, the other memory supplanted it. It played behind her eyes, relentless and vivid.
The hard, cold press of the crystal column against her back. The overwhelming heat of his body pinning her. Not the fight. What happened before. His hand sliding down, his fingers… She squeezed her thighs together, a sharp, involuntary motion. A fresh, hot pulse of wetness bloomed in the core of her, so sudden and intense it felt like a minor collapse.
She was soaking. Again. Just from thinking about it.
Guilt wrapped around her throat, cold and tight. Aang was healing in the next tent, his innocence, his trust, a physical weight on her conscience. And she was here, her body throbbing with the memory of his enemy.
She thought of Zuko’s smirk, the arrogant certainty in his amber eyes. You’re dripping for me, aren’t you?
Her own treacherous moisture proved him right, even now. Her breath came quicker. She imagined his hands, those broad, scarred hands that had wielded swords and fire, not on her hips, but lower, pressing the heel of his palm against her while his fingers—those same fingers— She flinched.
Her own hand moved.
It wasn’t a decision. It was a gravitational pull. Her fingertips brushed over the fabric of her trousers, against the swollen flesh beneath. A soft, ragged gasp escaped her lips. She closed her eyes, and it wasn't Aang’s face she saw.
It was Zuko’s. The sharp angle of his jaw. The feel of his teeth on her earlobe. The raw, filthy words he’d growled into her skin.
This cunt belongs to me now.
She pressed the heel of her own hand down, mimicking the pressure she remembered, and a choked whimper stuck in her throat. It was wrong. It was sick. He was a monster; he had hunted them, he had tried to kill Aang, he had thrown her world into war. And he had shown her a part of herself that was just as dark, just as monstrous.
She recalled the shocking penetration of his fingers, the stretch, the fullness. Her own finger traced a clumsy line over the seam of her trousers, applying a gentle pressure. It was pathetic, a ghost of what he’d done. She needed more. She was so wet it was a dull, aching shame, the fabric clinging to her.
She imagined him here, in this tent, pushing her down onto the bedroll. No more crystals, just rough canvas and his weight. His mouth on her neck, his hands tearing the clothes from her body, not with tenderness but with that same desperate, possessive fury. He wouldn’t be gentle. He’d take her, hard and fast, and she’d let him, she’d beg him, she’d scream into his shoulder so the whole camp would know what a lying, faithless whore she was.
The fantasy was so vivid, so degrading, that her hips bucked up off the bedroll once, a silent, frantic cry on her lips. Her finger pressed harder, circling, seeking the exact spot he’d found with such humiliating ease. She was right there, teetering on the edge, her body coiled tight with a need that felt deeper than the ocean.
Aang’s cough, dry and pained, sounded from the next tent over.
Katara froze. Her hand snapped away from her body as if burned.
The roar of silence that followed was deafening. The humid, secret warmth between her legs felt like a brand of treason. She stared at her trembling hand in the near-darkness, seeing not her own healing fingers, but instruments of a betrayal so complete it hollowed her out.
She curled onto her side, drawing her knees to her chest, a hot tear finally escaping to track through the dust on her cheek. The ache remained, a guilty, persistent throb. It was a prison he’d built inside her with his touch, and she had no idea how to escape it, or if she even wanted to.
