“Fire Lord Zuko, son of Ozai and Ursa, descendant of Sozin and Roku. You have been summoned by the messengers of Agni.”
Two booming voices echoed in his head. Zuko opened his eyes, momentarily blinded by the rays of the setting sun. He blinked, adjusting to the brightness of his surroundings.
He was standing on the bridge-like podium that connected the caves of the last dragons, Ran and Shaw. In fact, the ancient masters themselves stood on either side of Zuko and were addressing him through an amorphous mind-voice.
“We stand before you as the last of Agni’s children, old and nearing the end of our long lives. The lineage of dragons is on the brink of extinction. As the descendant of Sozin, you must bear the burden of your ancestor’s sins and restore our once illustrious race.”
“Wait, how am I supposed to do that?” Zuko shouted at the winged spirits.
“With the last of our power, we will grant you a part-draconic form on the day of the Summer Solstice. It is a borrowed vessel made from our own divine bodies. As we are dying, this body will only sustain itself for a fortnight. You must find a mate and birth to the next dragon heirs before our death, or the art of firebending will be lost to mortals forever.”
The dragons finished their speech, and before Zuko could ask what exactly they meant by ‘mate’ and ‘birth’, Ran and Shaw opened their jaws. The young Fire Lord was engulfed in a kaleidoscope of coloured flames, the last thing he remembered before waking up.
Aang was staying in the Western Air Temple. He had been there with his acolytes for a week or so, cleaning the place up chamber by chamber in hopes of a more extensive restoration in the future.
It was the end of lunch when Zuko’s letter reached him. Having had a satisfying meal among his acolytes, Aang was planning to show everyone around the northern wing of the temple and commence their afternoon cleanup.
Then, a messengerhawk had arrived, bearing a scroll with the Fire Lord’s official seal. The seal which Zuko had strictly reserved for official business. Aang opened it right away.
The first thing he noticed was that Zuko’s calligraphy looked far less perfect than it usually did. Stray ink splatters littered the page, at points obscuring rushed brushstrokes. Still, it was legible, if lacking the courtly pleasantries that Zuko hardly ever skimped on. Simple and straight to the point, Zuko’s message was deeply alarming.
Zuko needed him. The fate of the Fire Nation, maybe even the whole world hung in a balance.
Aang spoke to his senior acolytes right away, informing them that he was needed on urgent Avatar business. They were wonderfully understanding as always and reassured him that they could manage here until his return. A couple of the juniors helped him load up Appa’s saddle. Before long, he had said his goodbyes and was heading straight to Caldera City.
They made their descent under the blazing rays of the midday sun. Aang felt a pang of guilt for making Appa fly so fast in the heat, but the bison sensed his concern as acutely as if it was his own. Appa landed in the grassy stable grounds, not too far from the Royal Palace.
As Aang leapt from the saddle, he had not expected to see Ty Lee waiting for him. She closed the distance between them in an instant, her high braid bouncing with her dancelike steps.
“Thank the Spirits you’re here!” she exclaimed. Although she still smiled brightly, there was a slight furrow of worry between her brows. “Zuko’ll be very happy to see you. He’s been having a pretty miserable time, the poor guy-”
“What’s going on?” Aang interrupted. He liked Ty Lee and he knew she wouldn’t take offence to a bit of brashness during a time of crisis. “I heard there was some kind of disaster, but things look pretty normal to me.”
“You mean he didn’t tell you about the,” she whispered the next word, theatrically, “transformation?”
“The what?”
She hummed a little frustrated. “Well, it’s probably better if you see it for yourself. He’s in his room! Be sure not to let the servants see him, he’s pretty self-conscious and trying to keep things under wraps, as usual!”
He shot Ty Lee a sympathetic look. Whenever something went wrong, Zuko had always wanted as few people as possible to know, which sometimes left a heavy burden on his close circle. Aang thanked Ty Lee, leaving Appa in her care as he rushed toward the place in search of his boyfriend.
The corridor leading up the Fire Lord’s Suite was entirely void of servants. Its silence reminded him of their failed invasion all those years ago. Aang bounded through the vacant hallway with the same mounting dread as he had felt then.
He reached Zuko’s door, predictably unguarded. Aang slipped inside to the antechamber, just as empty and reassuringly pristine. Although the flowers had wilted, having not been replaced from the night before, Zuko’s collection of expensive and exquisitely painted vases stood in their usual places, unbroken.
Just then, Aang heard the muffled rustling of sheets, head turning in the direction of Zuko’s bedroom door. It had been left ajar and Aang raced to it.
Inside, it was dark. The curtains were firmly drawn, Aang suspected that they might have never opened that day. Similarly, the scones on the wall were unlit. In fact, the only light source in the room was a single flickering candle by Zuko’s desk.
As his eyes adjusted, Aang could just about make out the shadowy figure of Zuko, sitting up in the centre of his bed.
“You’re here,” Zuko said. There was a sort of breathless relief to his voice that put Aang on edge. What exactly happened here in the darkness?
“Zuko!” he called out, the mattress sinking under him as he leapt onto the bed. “What happened? Why is everything so dark?”
His boyfriend produced a flame in the palm of hand. It lit up their faces and Aang startled back as he saw two shining white horns, projecting out from Zuko’s silky black hair.
“Am I seeing things?” he asked.
“You’re not,” Zuko replied. His fingertips brushed against the ivory surface, as if to prove his point. Behind him, something reflected the light with a metallic sheen, rippling like water.
Aang looked around the room. “I’m gonna draw back the curtains” he announced.
Zuko didn’t protest, nor did he get up to help.
Once the room was bright and aerated, Aang returned to Zuko’s side.
There were indeed horns on top of his boyfriend’s head, growing out of his temples like pearl white branches of coral. The tips of them were blunt, yet gleamed like freshly polished jade. Strange as they were, they sat regally on top of Zuko’s head like a crown, complimenting his strong yet delicate features perfectly as if they had always been there.
Aang reached out slowly to touch them, broadcasting his action so that Zuko had time to pull away if he desired. To his surprise, Zuko actually tilted his head towards him. One ivory horn rubbed against his open palm like the ears of an affectionate rabbitcat. He could appreciate the fine texture of the bony surface, covered in little ridges like cliffsides eroded by the crashing waves.
He took the horn between his thumb and forefingers, sliding up and down its midsection where it branched out into smaller nubs. At his touch, soft moans escaped Zuko’s petal pink lips. Aang’s hand worked up to the top, thumb rubbing over the tapered end in a circular motion. Zuko moaned louder, his outstretched neck bobbing attractively.
“Does it hurt?” Aang asked.
“No…It’s just- Ah! Sensitive,” Zuko said.
Zuko was always gorgeous, Aang knew this well. But never more so than when his face was flushed with arousal and his eyes gleamed darkly with hunger.
“What about here?” Aang asked, fingers drifting down to knead the base of his horns.
Zuko shuddered. His lips were softly parted as he whispered, “More,” in a keening whine, eyes half-closed and glazed. Who was Aang to ignore such a simple request?
The horns were not the only addition. Spurred on by Zuko growing arousal, a magnificent red tail undulated behind him like the body of a viperpython. Shimmering scales caught the light in flashes of copper as the shadows slinked into a deep maroon.
With one hand occupied massaging the base of Zuko’s horn, he reached out with the other to stroke his tail. It slid willingly into his grasp and he stroked cream-coloured fur that lined its spine, marvellously soft and ruffling ticklishly as the tail moved. Under his palm, its sides were feverishly warm, the scaled surface rippling against him as smoothly as parting waves. He petted the tail as it twisted around him affectionately. It narrowed at the tip, ending in a leonine tuft of hair that brushed against his cheek, drawing out pearls of laughter.
Zuko squirmed as Aang doted on his new appendage. The colour in his cheeks had grown darker until it matched his scar. His golden eyes looked back at Aang with a sidelong glance, dark eyebrows raised.
“Too much…” he gasped.
Aang released the tail with no small amount of reluctance. It slithered away from him, resting on Zuko’s lap, as his boyfriend slumped against him with a sigh. A horn poked the side of his head, so Aang repositioned them both so that they sat comfortable with their backs against Zuko’s ample nest of pillows.
Zuko breathed out a hot puff of smoke. His earlier arousal had seemingly simmered down and his face bore his usual expression of grim determination. He turned to face Aang, pink lips pursed in a tight line.
“I need your help,” he said.
Aang smiled placidly, hands raising to smooth away the line of worry from his boyfriend’s forehead. “I know,” he said. “I got your letter. Though, it didn’t seem to tell me all that much.”
Zuko leaned into his touch like before, sighing defeatedly. “You remember Ran and Shaw, the Dragon Masters? I saw them in a dream. They’re dying.”
“Oh…”
“I know, Aang, it’s… not great,” Zuko placated rather gracelessly. He reached out to hold his other hand, squeezing softly as he usually did when comforting Aang. A fondness spread inside him at the familiarity of the gesture.
“Anyway,” Zuko continued. ”If there are no more dragons in the world, then apparently firebending itself would cease to exist. Which would be-”
“Awful,” Aang said.
Zuko regarded with wide eyes, like he had seriously expected Aang to say something else. When Aang met his gaze, he turned away, looking down at their joined hands.
He remained silent for a bit, then nodded. “Yeah, it would.”
“Why do you sound unconvinced?”
He tilted his head back, white horns shining radiantly as they caught the sun’s rays. “Doesn’t it sound a lot like karma?” Zuko spat out. “My great grandfather wiped out your people. My grandfather deprived the Southern Water Tribe of its benders. Fucking Zhao killed the Moon Spirit. At this point, don’t we deserve it?”
As Zuko spoke in increasingly passionate tones, his grip on Aang’s palm tightened and released like the spasming motions of a dying sparrowkeet. By the end, his voice had crescendoed into an anguished fervour. He turned to meet Aang’s gaze with golden eyes blazing.
Concerned as he was about Zuko’s agitation, Aang remained steadfast in his conviction. The laws of this universe demanded balance, he knew that better than anyone. He also firmly despised the sort of retributive justice that Zuko described.
With both hands, he kneaded at the tension that persisted in Zuko’s stiff grip. A beatific smile graced his lips as Zuko studied him with a sort of sorrow. Aang continued to intertwine his fingers with Zuko’s as he massaged the sides and knuckles, digging into the tense flesh.
“We all deserve second chances, you know that more than anyone,” he said. “Besides, you wouldn’t have called me here if you really believed that.”
Zuko’s throat bobbed, eyes narrowed in scepticism. “What if I was just selfish?” he said in a forceful exhale. “Have you considered how bad it would be for me, as Fire Lord, if firebending disappeared permanently during my reign? Maybe I just called you because I didn’t want a whole nation to turn on me anymore than they already have.”
He had been patient so far. Even if he hadn’t agreed with Zuko’s initial argument, there was at least some logic behind it. This time, however, Aang could see his self-deprecation for exactly what it was.
Aang sighed a tad dramatically. “Even after all these years, why can’t you just admit that you’re a good person who does good things for good reasons!”
Zuko gaped, scandalised. When he opened his mouth to bite back, he didn’t have an argument, just a throaty groan, accompanied by a puff of smoke.
Ignoring him, Aang continued, “And anyway, why would I, as the Avatar, just let firebending disappear from this world? How is that at all maintaining balance?”
“Ugh, I knew you would say that,” Zuko muttered with no real bite behind it. That little frown of his melted away into a smile, knitted brows giving way to soft, shining eyes. Zuko gazed fondly at him with a reverence that was hardly uncommon between them. Yet today, his jadelike horns suffused the light around him in a hazy halo. The effect was otherworldly and enchanting.
Aang felt his breath in his throat, leaning forward for a kiss that Zuko accepted readily. Their lips locked with hunger, Zuko’s hand coiling possessively around the base of his neck.
“Wait,” Zuko panted. “Let me finish telling you what happened.”
Aang hummed in approval, his fingers idly playing with Zuko’s long locks of hair. “Is this about your new look?” he asked with a grin.
Zuko’s eyes flitted nervously. “So about that,” he started, uncharacteristically hesitant. “When the Masters appeared in my dream, they said they’d grant me this… part dragon body, so that I can… ‘mate’ and… ‘birth’ dragon heirs’...”
Aang let go of the strand of hair he had been playing with, staring at Zuko, who had gone redder than his scar.
“Say something,” his boyfriend hissed.
“Umm…” Aang trailed off. “So, you called me here to… knock you up?”
Zuko’s features contorted in a frustrated groan, rubbing the space between his eyes defeatedly. “Yeah, I guess I did,” he admitted.
He looked up at Aang from under his lashes, and asked, “Is that… okay with you?”
“I’m trying really hard not to jump you right now.”
Zuko’s breath hitched and he averted his eyes, flustered. “Well, you can stop trying now,” he said, the corners of his mouth raised ever so slightly.
Aang leaned forward to kiss him. “Can’t argue with that,” he said, smiling, as they parted.
His fingers reached forward to loosen the tie of Zuko’s silk robe, letting Zuko undo his sash in turn. Aang’s robes slipped off with a shrug of his shoulders, tumbling somewhere onto the bed in a disregarded heap. He parted Zuko’s robes, pushing the crimson material off his shoulder.
“Wait!” his boyfriend called out. “I have something else to show you.”
He took Aang’s hands into his own, guiding them over his broad shoulders to reveal more of his pale skin and toned torso. Zuko’s physique was as beautiful as ever. Aang paused to admire it, longing to kiss the fine bow of collarbones, to squeeze his bulging pectorals and lovingly caress his narrow waist.
Zuko parted his robe further down about his hips, shifting slightly as he spread his legs. Following his waist, he caught sight of those tapering muscles that invitingly drew his gaze to his groin.
There, peeking out between his parted thighs, were glistening pink folds of a cunt.
Zuko felt Aang’s ravenous stare, so obviously transfixed by his changed body. His boyfriend leaned in to admire his new cunt, hot breath ghosting along Zuko’s inner thighs. He desperately wanted to close his legs, feeling himself grow wetter from Aang’s attention alone.
A finger parted his bright pink folds, the tip of it wet even before it reached his entrance. It drew a reverent sigh from Aang’s lips, as he showed off the digit, coated in the product of his arousal.
“Spirits, can’t wait to be inside you,” he whispered along the shell of Zuko’s ear.
His hand returned to Zuko’s sopping cunt, spreading apart his inner folds as he stroked either side of them with two fingers.
“Did you play with yourself earlier?” Aang asked. Zuko could tell from the gravelly timbre of his voice that Aang was just as aroused as he was. He gave him a shy, curt nod.
He did try to touch himself earlier, but the novelty of the cunt alluded him. It was so different from his cock, either far too sensitive or near inert. Just as he thought he had achieved a good amount of friction and pace, his climax somehow slipped out of his grasp.
“I- Ah! Tried… but it, mhmm, didn’t feel as good!” Zuko added.
Aang hummed, reassuringly. “It’s your first time touching a cunt, isn’t it?”
Zuko loved and hated his relative inexperience compared to Aang, despite being the older of the two. He had touched Mai when they were dating, but only briefly and over her clothes. Compared to those fumbling touches of youth, this was an entirely different experience.
Aang’s fingers skimmed over the peeking nub of his clit with a featherlight touch. Waves of arousal ran up Zuko’s spine. He gasped, hips canting forward to seek friction. Aang drank up his moans with an open-mouthed kiss, working Zuko’s sensitive cunt to the brink of climax.
Right as Zuko felt it creeping over him, Aang’s fingers flew off, their lips parting. Zuko whined pathetically, rocking forward, searching for something that wasn’t there.
“Aang…” he drawled.
His boyfriend kissed the base of his horn apologetically. “I really wanna see you get yourself off, can you do that for me?”
Zuko whined in frustration. “You know I don’t know how,” he muttered, balled fists hitting Aang’s chest in mock aggression.
“I’ll guide you,” Aang said, more a command than an offer. When Zuko continued to glare sceptically at him, he added, “I’ll finger you with my other hand, you’ll like it, I promise.”
A fingertip brushed along the entrance of Zuko’s cunt and pushed into the wet heat with little resistance. Zuko shuddered at the intrusion. Was it good yet? He wasn’t sure, but he didn’t want Aang to stop, so he put aside his scepticism, his hand hovering over the folds of his cunt.
“Good boy,” Aang said with a grin, pumping his finger in and out of Zuko’s tingling walls.
He moaned, maybe from the praise, maybe purely from the sensation of being opened up. With the soft pad of his middle finger, he pressed down on his clit, a little spark of arousal crept up his spine, just like it did earlier when Aang touched him. He attempted to copy his boyfriend’s movements, rubbing the sensitive nub, only to cry out when it was too much.
“Go gentler,” Aang murmured. “You’re so wet down here.” The single finger withdrew from him, indeed slick with Zuko’s bodily fluids. A second joined it as Aang prodded his entrance once more.
Zuko felt considerably more stretched this time, the two digits only sinking past the second knuckle before meeting his resistant inner walls. Aang let out a little hum before spreading his fingers apart, wiggling them as he did so. The sounds his cunt produced, wet, sucking noises, brought a blush to Zuko’s cheeks and he shifted in Aang’s hold, embarrassed.
Aang kissed him as reassurance. His hand tugged on Zuko’s, encouraging him to touch himself again. “It’ll help you relax,” he said.
So Zuko tried again with softer touches this time. He circled the hood of his clit instead of rubbing it directly, gasping at how much better it felt when his digit accidentally strayed too close.
“Good, you’re doing so well,” Aang praised. “You’re so fucking hot.”
Zuko moaned, feeling the praise go straight to his clit. Touching it now felt incredible, arousal pooled hot in the centre of his belly.
Aang had managed to work both fingers in all the way. He crooked back his fingers, stroking a spot inside Zuko that had his back arching off the pillows behind him.
“Feels good?” Aang asked, as obvious as Zuko’s response was.
He whined, too far gone to answer Aang properly. It got the message across either way, as Aang crooked his fingers back again.
“Keep touching yourself, baby,” Aang said.
Zuko hated that petname, Aang only ever used it during sex and when he knew Zuko was close. It embarrassed him in the best of ways, to be taken apart so completely by his younger boyfriend.
Despite his annoyance, Zuko obeyed. With more practised strokes, he rubbed his between his fingers. A keening whine left his lips, so worked up by the friction he produced and Aang’s fingers working him open.
Aang began to pump his fingers again, now that Zuko’s walls were sufficiently relaxed. They reached deep into him before pulling out almost all the way, rubbing against the tingling neck of his entrance before pushing all the way in. He gasped the first time Aang did it, the sensation so different from a single finger.
Behind him, his tail was swishing, so overwhelmed by the sensation of Aang pushing into him. The undulations, involuntary as they were, made the sensitive body of his tail brush against the mess of pillows behind him.
Aang busied his mouth with soft, sucking kisses behind Zuko’s ears, the juncture of his neck, his collarbone, his chest. At last, the trail reached his pebbled nipples. Aang swirled his tongue around the hardened bud, as if to greet it. Zuko arched forward at the slightest graze of teeth and then shuddered as Aang closed his mouth around the nipple and sucked.
Unexpectedly, his orgasm washed over him in a crashing wave of pleasure. He felt himself constrict around Aang in little pulses, rolling his hips to force his fingers in deeper. Aang’s wrist dripped, coated with the fluids of his release as Zuko panted, exhausted, against his nest of pillows.
Despite having just came, Aang’s fingers continued to work in and out of him. Their incessant prodding made him tremble. At first, Zuko assumed his boyfriend was teasing him again. His eyes snapped open, ready to glare and give him a piece of his mind, until he saw Aang’s face scrunched in concentration.
“What’s wrong?” he asked, a pit of dread forming in his stomach.
Aang glanced up at him. “I don’t know, I feel something,” he said. His fingers prodded deep inside of Zuko, eliciting a jolt as Aang certainly pressed against something.
“It feels hard and round,” Aang described. “Don’t you feel it inside you?”
“Yeah,” Zuko replied, a little breathless from whatever it was stretching him alongside Aang’s fingers. “It feels… full all of a sudden.”
Aang withdrew his fingers from inside Zuko. They slid out of him easily enough, yet their displacement caused whatever it was inside of Zuko to follow suit. It travelled about halfway out of Zuko’s canal, getting stuck somewhere frustratingly close to the entrance.
Zuko huffed. The stretch on his already-sensitive walls was quite uncomfortable. He beared down on it, trying to force it out, which worked partially. Whatever it was, it was almost out of him, stretching open the ring of muscles around Zuko’s entrance.
“It’s coming out,” Aang said, as if Zuko didn’t already feel it opening him wide.
Aang traced the stretched rim of Zuko’s entrance, the sensation drawing a choking sob out of him. It was so strange, feeling himself gape around this object.
He looked at Aang, who was watching his lower half with a lustful gleam in his eyes. Something about that made the hairs on the back of his arms raise.
Zuko took a deep breath in, determined to squeeze it out with one firm push. With the exhale, he drew in his core, muscle rippling from the effort.
Sure enough, it worked. Something slipped out of him, and Zuko relaxed. The sudden loss of pressure against his entrance left him feeling empty, although not for long, as Aang pushed his fingers back into him.
He let out a choked back sob. “What are you doing?” he hissed out.
“Checking if there’s more eggs,” Aang said, like it was the most normal thing in the world.
“Eggs?”
Aang nodded, retrieving the object that had just been inside him and holding it up for Zuko to see. It was, indeed, an egg - slightly larger than that of a pighen’s and of stunning deep red hue.
“When the Masters said to produce dragon heirs, this must be what they meant,” Aang said.
Zuko snatched the egg from Aang’s fingers. It was still warm from his body heat, a fact that made him blush. Still, the warmth was pleasant, comforting like the warmth of a fresh cup of tea. He inspected its exterior, noticing speckles of purple against the deep red, like scattered constellations in the dome of the night sky.
“It’s not fertilised though,” he said, setting the egg aside on his bedside table.
“No,” Aang agreed.
With his fingers still inside Zuko, Aang pressed down on his stomach with his other hand. After a little more prodding, Aang looked up at him, face aglow.
“Zuko, there’s more of them! But they’re deep inside, probably in your womb,” he said.
“Womb?”
Aang gave him a puzzled look. “Yeah, I mean, those are normally present when someone has a cunt. And in your case, it seems to be where your eggs are sitting.”
Zuko exhaled. “You think there’s multiple?”
“There better be if we want to increase our odds of saving the dragons from extinction.”
Well. He couldn’t exactly argue with that.
Satisfied with his prodding, Aang slipped his fingers out of Zuko. He pressed a chaste kiss on Zuko’s scarred cheek.
“You okay, babe?”
Zuko rolled his eyes. “I’m not your ‘babe’, and I’m fine. Just coming to terms with what we’re actually doing here.”
“That’s fair,” Aang said as he studied him pensively. “You know, if you don’t want to do this, I could probably talk to the Spirits, do some Avatar shit, figure something out.”
Zuko looked back at him thoughtfully. As always, his boyfriend’s very existence was like a soothing balm. A sweet, placid smile graced his lips as he waited patiently for Zuko’s answer.
He considered his options, but ultimately one voice prevailed. And that was the voice of lust.
“I.. want you to fuck me, and, you know, fertilise the eggs.”
That sweet, little smile on Aang’s face broke out into the widest, most victorious grin. Zuko gulped, once again wondering what exactly he had got himself into.
“You want me to get you pregnant,” Aang said, huskily. “You want me to fuck your cunt and fill you with my seed.”
“Aang…” he said, shooting his boyfriend a warning glance.
He leaned in, nuzzling up against Zuko's face. “Am I wrong?” He pressed a kiss against his lips, pulling away briefly to catch Zuko’s reaction before diving back in.
Aang had yet to fully undress. The outline of his cock strained against the fabric, dampening it where the tip had been leaking precome. Zuko wondered if it had been hard like that all this time, feeling vaguely guilty for neglecting his boyfriend. He untied the knot in the front and pushed down the waistband of Aang’s trousers, pulling down his red briefs, too. Aang shucked them the rest of the way off, tossing them to the side.
At last, Aang’s cock was free, the sight of making Zuko’s mouth water in anticipation. He wrapped his hand around it, thumb circling the sensitive cockhead before spreading the precome that gathered there down along the shaft. Zuko worked up and down the length a couple of times, savouring how it twitched and grew to full hardness in his grasp. With the guttural moan, Aang canted his hips towards Zuko’s.
He guided his boyfriend’s cock to his cunt, gasping as it slipped inside of him.
Aang pushed in, head slipping easily past his gaping entrance. “Spirits, you already feel so sloppy. Feels like I can start fucking into you straight away,” he said, breathlessly.
Zuko panted, still unused to the intrusion. Even if he was loose, Aang cock was still considerably longer and thicker than the eggs or his fingers. Still, the thought of Aang ramming straight into him, taking him like it was all that he was good for, lit a spark in Zuko.
“Why don’t you?” Zuko goaded. “Fill me up.”
Aang groaned, pushing deeper into him. “Believe me, I will.”
They moaned in unison. Zuko clung onto Aang’s back, nails digging into corded muscles as Aang’s cock filled his inner walls. He thrusted experimentally, little staccato pushes that had Zuko arching, pushing his hips forward to bury it deeper inside him.
Satisfied that Zuko was ready, Aang built up the pace. Compared to the usual pounding that Zuko preferred, Aang thrusted into him at a measured, considerate pace. Zuko blamed the damn eggs.
Zuko pressed a little below his navel and felt them, a whole clutch of them. Just sitting deep inside his womb, waiting to be fertilised. He moaned. Unconsciously, he spread his legs further apart, digging his ankles into the divots of Aang’s back.
Although they did move with every thrust, they were so tightly packed inside of him that the risk of them knocking against each other and cracking felt rather minimal. With that reassurance, he arched into Aang’s thrust, whining for his boyfriend to fuck him faster.
Aang picked up the pace, still not quite pounding to Zuko, but still, an improvement from the leisurely fucking from earlier. His hands roamed over Zuko’s torso, stroking his sides and tweaking his nipples. Then, one drifted to the back, wandering across the length of his tail, before Zuko could even protest the onslaught of sensations.
He pushed back against Aang’s chest, weak with pleasure. “Stop, you’ll make me come,” he panted.
Aang’s hands stilled, cupping the side of Zuko’s face. “But I want to make you come,” he said guilelessly, leaning in to press against his lips.
Zuko whined, hips squirming in a way that made it very hard to not thrust into him. “If I do that, the eggs will come out before you’ve fertilised them. I need you to come inside me. But don’t make me come, got it?”
Aang hummed, rolling his hips deep into his boyfriend.
Zuko moaned filthily. “I thought I told you not to make me come,” he whined, too turned on to sound even mildly annoyed.
“Sorry, can’t help the fact you like my dick so much,” Aang teased. He pushed him back against the pillows, one hand on his hips, another holding his thigh open, poised to start pounding him properly. “Guess you better do your best to hold it in.”
Aang thrusted into him at the usual pace, punishingly fast, with a snap of his hips. Zuko gasped out a choked moan, the sound dying somewhere in the back of his throat as Aang pulled out and drove back in.
All Zuko wanted to do was lay back and let Aang have his wicked way with him. He felt his orgasm building with every obscene squelch of his cunt as Aang fucked into it like a man possessed. Caught between meeting his thrusts and shying away from the growing pleasure, Zuko squirmed in place.
A twinge of pain made itself known at the base of his spine. Fearing the contractions had returned, Zuko drove forward onto Aang’s dick in the thought that maybe his cock would stop the eggs from coming out all at once.
Aang groaned, the sudden movement burying him deeper into Zuko’s wet heat. He grabbed the flesh of his thighs, pushing him back, determined to thrust back into him just as deep.
Zuko let out a pained cry and Aang loosened his grip. His cock eased out of Zuko and he sat back to give his boyfriend some space.
“What’s wrong?” Aang asked. One hand stroked Zuko’s cheek, thumb wiping away the tears that pooled in the corner of his eyes.
“It’s nothing,” Zuko said. Then, after a pause, he added, “It’s the stupid tail. It’s digging into the base of my spine and it kinda hurts.”
Aang frowned, “‘Kinda’ or a lot?”
Zuko glowered but corrected himself, “Fine, it hurts a lot!”
“Good boy,” he said when Zuko admitted it, kissing the side of his face. “Let’s switch positions, then.”
He shuffled back, allowing Zuko to lean forward, chasing his lips as he released the tension in his lower back. Aang reached forward to embrace him, working his fingers into the muscles that lined either side of Zuko’s back as his tongue slipped past his open lips. He kissed him, grinding their hips together as Zuko settled on top of him, his thighs parted, straddling Aang’s waist.
Aang’s hand drifted lower, grabbing handfuls of Zuko’s plush ass, digging his fingers into the ample flesh. Zuko wrapped his arms around Aang’s shoulders almost instantly, kissing him back possessively. His hips rose, ass swaying in Aang’s palms as his boyfriend positioned his sopping, wet entrance over the head of his cock.
Zuko plunged down, moaning against Aang’s lips as they parted with a wet trail of spit. Aang groaned, thrusting in short pulses against Zuko’s tight heat. He pulled Zuko up by the ass and brought him down as his cock drove back into him. Zuko let out a muffled moan by his ear and he turned his head to seek his lips once more.
They fucked like that, Aang moving Zuko around like puppet without strings as his orgasm crept up on him. He held Zuko down by his hips, his cock thrusting into Zuko’s cunt at a brutal pace. Zuko cried against his shoulder, reduced to little whimpers as he struggled to keep it together. Then, with one last snap of his hips, Aang came, buried deep inside of Zuko, who sagged bonelessly against him.
Aang slumped back onto his elbows, panting as Zuko’s upper half crashed down with him. His thighs, however, held Aang’s waist in a steel grip, trapping his cock firmly inside of Zuko’s cunt.
Although Zuko was just as breathless as he was, there remained a sort of cognisance about him. Aang could feel the post-orgasmic sleepiness taking ahold of him, the weight of Zuko’s chest against his own was so comforting that he just wanted to close his eyes for a little while.
But then, that pleasant weight left as Zuko leaned back. He sat on top of Aang’s hipbones, shifting his ass in a way that made Aang’s softened cock brush against his inner walls, bordering on overstimulating. A finger traced the base of cock where he and Zuko were still connected, gathering some of the semen that escaped Zuko’s tight heat and slipping it back in.
Fingernails scraped past his spent length in Zuko’s efforts to not waste a single drop of come. Aang felt himself hardening again in spite of the tiredness that clung to his bones. He stretched out a hand and Zuko grasped it, pulling him up to kiss him fervently.
“Can you go again?” he asked when they parted.
Aang nodded, fingers wound around silky black locks of hair. He kissed the base of Zuko’s horn tenderly. “I want to fuck you from behind,” he said.
Zuko nodded. He slipped off Aang, a hand cupping his cunt to staunch the backflow of come. It leaked out of him anyway, fat, white globs of it coating his digits as he whimpered in displeasure. The sight of him made Aang’s dick twitch. Extinguished flames of his lust were lit once more and he took his wet cock in his hand, spreading the mixture of his come and Zuko’s slick down his length as he shuffled out from under him.
He knelt on the bed, admiring the view of Zuko’s used pussy, outer lips plump from a recent pounding. A pearly blob of semen oozed out from his gaping entrance. Aang scooped it up in his fingers, pushing it back in as Zuko moaned. His back arched, pushing back his cunt towards Aang, presenting it to him, ready for another round.
Zuko pushed his hips back, evidently seeking Aang’s touch, as his fingers fed more fleeing rivulets of come back into his hole. The tail swayed in front of Aang, undulating seductively as it brushed against his chest.
Eventually, it found the slope of his shoulders, wrapping itself around them like a very friendly shawl. The tapered end brushed against his collarbones, oddly sensual in the slow way it dragged itself along Aang’s chest. He bent down to kiss it, the soft tuft of fur tickling his lips like a feather.
Sweet as the gesture was, it drove Aang crazy. Not knowing what else to do with his unfurling arousal, his nails dug into the flesh of Zuko’s hips. He nuzzled the thicker end of the tail that rested on his other shoulder and Zuko let out a keening whine.
His fingers left Zuko’s cunt, circling his cock. He lined it up against Zuko’s entrance and drove home in one fluid thrust. A hiccuping moan slipped past Zuko’s lips. Both of hands held up his hips with a grip tight enough to bruise.
Aang pulled out until only the fat tip of his cock remained inside Zuko’s cunt. A frustrated cry left Zuko’s lips. Aang thrusted back in with the full force of his snapping hips, the plush flesh of Zuko’s ass jiggled from the impact.
Zuko’s head sagged forward onto the mattress. Through eyes half-shut in pleasure, he watched as Aang drove into him at a relentless pace. Come frothed forth where they were connected. He must be gaping, after all they had done.
It was such a heedy thought, the cunt had just been granted to him this morning and yet it was already loose and well-used before the sun had even set. From the way that he fucked him, Zuko felt as though he had been thoroughly claimed by Aang’s thick cock. His horns rubbed furiously against the silken sheets, Zuko’s mind melting from the sensation. All he could focus on was the thought of Aang coming inside, of filling his womb to the brink with his seed. Of claiming this new body of his so thoroughly with his essence, of feeding the new life that grew inside of him. Of breeding him.
A litany of moans overflowed from his lips. Aang leaned forward, covering Zuko’s body with his own. The heat of their breaths intermingled as he pressed hungry, open-mouthed kisses along the shell of his ear, fucking him deeper as his tongue traced the contours of Zuko’s horn. Zuko knew he was close. From the sharp, stuttering thrusts, so was Aang.
Dimly, he knew he should tell Aang to stop, to ease up on his thrusts and kisses if Zuko wanted even the smallest chance of suppressing his orgasm. But as he squeezed tighter, Aang groaned, deep and guttural, into his ear. His hips snapped against Zuko’s more desperately than ever.
“Fuck, so good, babe…” he murmured, his voice dripping low and pleased. “Gonna fill you up so well, make as many dragon babies as possible.”
He whined at Aang’s words, Zuko could swear he was doing it on purpose. The filthy praises continued to pour out of his boyfriend’s lip as a hand snaked down his torso. As if his control couldn’t be tested any further, Aang rubbed his clit in time with his punishing thrusts.
Zuko’s resolve crumbled away in an instant. He clawed at the sheets, ripping into them as his cunt clenched around Aang’s cock. His orgasm crashed into him in one great shuddering wave. A long wail left his lips, foreign to his ears. Aang fucked him through it, hand thankfully retreating from his oversensitive clit and lifting up Zuko’s hips, slack from having just come. He whimpered a little, so spent and worn out as he received Aang’s thrusts.
It wasn’t long until Aang came. His hipbones dug into Zuko’s back, the poor tail flattened between them, as released deep inside of Zuko. Through the head of his cock, he could feel a familiar hardness behind the entrance to Zuko’s womb - the eggs, ready to be fertilised. He thrusted down against them, his release coating their hard shells.
Under him, Zuko let out a satisfied groan. Aang, suddenly very conscious that he was crushing his boyfriend, scrambled up onto his elbows and knees. Zuko whined in complaint.
“Don’t move, you’ll waste it,” he murmured, half-drowsily.
Aang laughter rumbled against both of their upper halves. “Fine, fine,” he agreed. “But this can’t be good for your tail.”
Summoned by Aang’s sympathy, the long appendage wriggled. Aang pushed up onto his hands so that it could move more freely, and it did so, affectionately swiping at his jaw with its fluffy tip. His lower half remained flushed against Zuko’s, which wasn’t so bad, but strenuousness of their activities and the two orgasms had him wiped out. He imagined Zuko was not far behind.
With one fluid motion, Aang rolled them onto their sides. His legs wound around Zuko’s, keeping their lower halves firmly connected. He embraced his boyfriend loosely from behind, mindful of the pressure on his tail that flopped out from this gap between their chests, lazily stroking Aang’s flank.
Zuko hummed, content with the new position. Exhausted, he drifted to sleep in Aang’s arms.
