"Remember, a firebender's power comes from the breath, not the muscle," Zuko told Aang, recalling his uncles words. "Close your eyes and keep breathing." They were on a remote island near Crescent Island, and Zuko had chosen this open field of rocks as their training ground so they wouldn't burn anything by accident.
Zuko took a couple of steps closer and gently placed the palms of his hands on Aang's stomach and back. The thin air nomad tunic felt soft against his rough hands, and he could feel the Avatar flinch at the unexpected touch. But Aang continued his breathing exercise, and Zuko could feel his slim torso expand with every breath.
"You are breathing like an air bender. Control your breath instead of letting it pass through you. Firebending requires focus, determination, and will power. You can't do that if you are pretending to be a leaf in the wind."
"Yes, Sifu Hotman," Aang giggled. This felt like his first firebending lesson with Jeong Jeong.
"And no talking!" Zuko snapped, raising his voice. He was going to teach Aang the only way he knew how to teach: with seriousness and discipline. When Katara and Aang approached him a couple of weeks ago about resuming Aang's firebending training, they hadn't really explained anything other than that he should keep it a secret.
"Better," he nodded as he felt Aang's breathing become more regular. His hands could feel Aang's slim waist relaxing as he became accustomed to Zuko's touch. He suddenly felt very awkward standing so close to his friend. Thank the spirits that Aang's eyes were closed, because Zuko could feel himself blushing. It was because he could smell Aang's scent. He smelled like fresh air, light and slightly salty from the sea. Zuko caught himself staring at Aang, his eyes wandering from the blue tattoo on his head down to his delicate and peaceful face with the small nose and the soft eyelashes…
Zuko shook his head to get rid of these thoughts. He didn't like where his mind was going with this.
"What?" Aang asked, feeling Zuko's movements through his hands.
"Nothing. Now show me what you've got!"
Aang took a deep breath and threw the palms of his hands out. Nothing happened.
"What's the matter?" Zuko demanded, letting go of Aang's waist. This was even worse than when he started teaching Aang at the Western Air Temple. He had assumed he was just going to improve the Avatar's firebending, not start from the beginning.
Aang sighed. He had known that he would have to explain this to Zuko at some point, but that didn't make it any less embarrassing. After he had defeated the Firelord, everyone expected him to be the perfect Avatar.
"I kind of… how did you put it, 'lost my stuff'? I can still control fire, I just can't create it anymore," Aang admitted.
"Who else knows about this?" Zuko asked. Not being able to firebend was a weakness people should rather not know about the Avatar.
"Only Katara." It was her that convinced Aang to seek Zuko's help when he told her a couple of weeks ago.
"Good. When was the last time you created fire?" he inquired further.
"A couple of months ago." Aang definitely wasn't going to tell Zuko about the other changes that had begun around that time. Not even Katara knew about that.
Zuko rubbed his hands against his face, frustrated. This was going to be a lot more difficult than he imagined.
"Listen, for now we should just concentrate on…" he began, but Aang cut him off.
"Look!" he exclaimed, "A porcupine-lizard!" and sped off in a gust of wind. Zuko couldn't believe it. They had just celebrated the Avatar's eighteenth birthday – the perfect cover for Aang to visit the fire nation as he now realized – but more often than not he still behaved like a twelve-year-old child.
"Zuko! You gadda come see this! It's a whole family!"
Zuko growled in frustration. Discipline had never been Aang's strong suit. With a few jumps, he caught up to the air bender and shot a fire bolt against the rock next to him, and the porcupine-lizard family scattered away.
"Did I tell you to abandon your position?" he growled.
"Aw, Zuko! Now you've scared them away!" Aang cried out, immediately looking to see where they had gone. Zuko folded his arms across his chest and gave him a stern look.
"I'm sorry," Aang apologized, lowering his head when he saw the look on Zuko's face. "Sifu Zuko," he added.
Zuko immediately forgave him, but he was careful not to let it show.
"Let's get back to work," he said, jumping back over the rocks to their training area. "Besides, porcupine-lizards are dangerous when they have young. They can bite you, and uncle told me their spikes are poisonous."
Zuko gazed at the stars above and tried to concentrate on the soft sounds of the waves in the distance instead of Aang's teeth chattering next to him.
"Zuko, I don't understand why you didn't just bring tents, it's freezing!" Aang complained.
"I already told you, it's a firebending exercise. Once you are able to create your own fire, you'll be able to keep yourself warm anywhere." Zuko replied. How was he supposed to have known Aang couldn't do that anymore when he prepared for this trip? The Avatar had done very well at redirecting and blocking fire during their training the rest of the day. But those moves were much more similar to other forms of bending. It was the ability to create the element you bend that made a firebender so unique among benders, but they hadn't made any progress with that.
Zuko thought about possible reasons for Aang's block. When he had joined the Avatar's cause at the Western Air Temple, his firebending had temporarily weakened, but it had still been there. Then he remembered when he first met Mai in his early teens, his firebending was somewhat erratic for a while. Iroh had consoled him that puberty sometimes had that effect. But Aang was too old to still be in puberty, and besides, Zuko's bending had been unpredictable and fickle, but not gone. The only other reason Zuko could think of was when Iroh tried to teach him to create lightning. He had said Zuko had to first deal with the turmoil inside himself to acquire peace of mind. But when he had joined the Avatar's cause, and even after the war had ended, he still hadn't been able to create lightning.
Frustrated, Zuko decided to figure this mystery out tomorrow and tried to fall asleep. But Aang's shivering was too distracting.
"I thought you monks didn't need the luxury of soft feather beds…" he teased. He scooted closer on the small blanket he had brought for them to sleep on, until the slim shivering figure of Aang was within his reach. He stretched out his arm and placed his hand on Aang's back between his shoulder blades. He could feel the lean muscles under his fingertips tense up. Aang was indeed cold. He took a deep breath and let his energy flow from his stomach, through his chest, shoulder and fingers into his shivering friend.
Aang's eyes flew open when he felt Zuko's touch. Like this morning, it felt weird to have Zuko touch him. Unlike his friendships with the others, his friendship with Zuko did not include physical gestures like the hugs from Katara, Sokka's hand on his shoulder, or the occasional friendly punch from Toph. Of course Zuko had touched him before during training, when he had corrected his form or taught him how to block. But this was different. Gentle, lingering, and soft… not what he had imagined Zuko's touch to be like.
Then a warm pulse spread from Zuko's hands, seeping through his body and warming every inch of his shivering limbs.
"Wow!" Aang cried out in surprise, "Zuko, that's amazing! You've got to teach me that trick!"
"Shuttup and go to sleep," Zuko muttered, trying to hide the fact that he was smiling. It was so easy to impress the air bender.
A couple of hours later, Aang woke up, shivering again. Zuko's hand was no longer there to warm him.
"Zuko!" Aang whispered, "gimme me your hand again!"
But his friend was asleep.
He sat up and peered into the darkness, trying to make out the shape of Zuko next to him. He was lying on his side, his head resting on his right arm, with the left arm that had provided so much warmth to Aang lying loosely on the thin blanket. Aang contemplated snatching the blanket away from under him, but it would have been too small anyways. He decided the best thing to do was scoot as close to Zuko as possible without waking him.
So he gently lifted Zuko's arm, careful not to let his cold fingers touch Zuko's warm skin, lay down beside him and slowly lowered his arm so that it rested heavy on Aang's waist. This was just like when he used to curl up between Appa's feet. He could feel Zuko's warmth glowing behind him, slowly warming his back, and dozed off to the feeling of Zuko's hot breath against the back of his neck.
Half asleep, Aang scooted even closer, reached for Zuko's arm that had been lying across his waist, and hugged the warm hand of his friend to his chest.
Suddenly Zuko's body jerked up.
"Wha-?" the firebender cried out in confusion, tripped in the darkness, and tumbled down the rock into the darkness.
"Ow! Supid beasts!" he heard Zuko roar and suddenly the night was ablaze in hot flames, as his friend was chasing away the porcupine-lizards.
"I'm sorry! Are you okay?" Aang shouted above Zuko's cursing.
"I fell into your family of porcupine-lizards…" Zuko muttered as he limped back to the blanket. "They bit me!"
In the light of Zuko's flame, Aang could see that on Zuko's inner thigh, his pants were torn off and blood was dripping out. Then Zuko raised his arm and flinched. Three spikes stuck out through his royal robe on the side of his chest.
"Great," Zuko grumbled, pulling out the spikes.
"I can heal you!" Aang immediately offered, helping his friend sit back down on the blanket. Katara had been so proud of him when he finally mastered the healing technique of waterbending.
"You've got to get the venom out first…" Zuko cringed, slowly lying down.
"How?" Aang asked, perplexed. He had learned the healing technique, but he was not a trained healer.
"You suck it out and spit it out, of course! Hurry, I can already feel my arm getting numb!"
"Okay, okay!" Aang tried to calm Zuko down. He clumsily fumbled with the sash that Held Zuko's upper robe together, finally pulled it open, and unfolded the silken sheets of fabric until he could feel the hot skin of Zuko's chest against his fingertips. When he brushed aside the last layer of silk, he froze in surprise.
Of course. The scar. Aang hadn't been there, but Zuko had been hit in the chest by Azula's lighting pretty badly. It looked similar to Aang's scar on his back, but not quite as deep.
He caught Zuko's eyes and saw a flash of embarrassment before the firebender composed himself again.
"Sorry…" Aang muttered and bent down to examine the puncture wounds the spikes had left behind on Zuko's pale body. The warm light of the flame Zuko was maintaining in his other hand showed the three marks: one in Zuko's side, one further up, and the last one just below Zuko's armpit.
Without daring to look at Zuko's face, he leaned forward and placed his mouth over the first wound. As soon as his cool lips touched Zuko's hot skin, Aang could feel a familiar feeling awakening in his body. He began sucking and immediately felt the bitter taste of the venom in his mouth.
He spat it out and returned his lips to Zuko's skin. Zuko's body was just as firm and muscular as he had imagined it would be, and the feeling of his face pressed against him strangely made his heart beat faster.
"What were you doing, anyway?" Zuko asked, his low husky voice not quite hiding the pain he was in.
When the bitter taste was gone and Aang tasted blood, he spat out again.
"I'm sorry, I didn't mean to startle you. I was just cold, so I…" Aang mumbled embarrassed, and bent down to suck the second wound. He didn't know why, but his heart was pounding as he gently placed his hand on Zuko's shoulder to steady himself and get a better angle. He could feel the blood rushing to his cheeks as he saw that his nose was pressing against Zuko's skin only inches from his nipple.
"Well, I'm not your pillow, and I'm not your furry bison. Next time just wake me and I'll warm you with my hand again."
Aang felt a twitch of embarrassment, but then he realized Zuko was just being snappy. He knew Appa's name, he just wanted to make Aang feel bad for being cold. Aang not-so-gently lifted Zuko's arm out of his sleeve and folded it up to get better access to the final puncture wound on the lower end of Zuko's armpit.
"His name is Appa, and you know it," Aang retorted and leaned down one last time. As soon as his lips touched Zuko's skin, the strange feeling in his body returned, this time stronger than before. Zuko's armpit was even warmer than the rest of his body, radiating heat against his cheeks as his nose lighly touched Zuko's whisps of armpit hair. He had never paid much attention to Zuko's smell, but now it filled his senses completely.
Clean, manly, with a slight note of the oils Zuko had started using since he lived in the palace, and just… so much like Zuko. Whenever he had taught Aang firebending and moved close to him, Zuko's scent was there. This morning when Zuko had touched his stomach, he remembered, it was there. Just hours ago when he had fallen asleep in the comfort of Zuko's warmth, it was there.
Without thinking, Aang went through the motions of spitting out the venom and returning his lips to Zuko's body, even though he had already sucked out all the venom at this point. He grew curious and a little bolder, so he dug his nose a bit deeper into Zuko's armpit as his mouth closed around the wound.
As he took in Zuko's intoxicating smell, a thought flashed through his mind. He wanted to taste Zuko.
Without thinking, he opened his lips a little wider and let his tongue flick out against Zuko's warm skin, cautiously licking and tasting him. It was better than he had imagined, slightly salty, and his eyes fluttered shut, his eye lashes brushing softly against Zuko's skin.
"What are you doing?" Zuko barked, and Aang snapped back to reality. How stupid of him, of course Zuko could feel Aang's tongue against him.
"Just checking if all the venom was out," Aang lied, backing away. "You're fine now." As he retreated, he felt a familiar sensation in his crotch, of his private parts pressing stiff against his air nomad tunic.
Careful to hide the tent in his pants from Zuko, Aang relocated between Zuko's sprawled legs to take care of his bite marks. He was so embarrassed. Why did this have to happen now? He thanked the spirits that his crotch was hidden in the shadows from Zuko's flame.
"Oh, thanks, Aang," Zuko muttered.
"No problem," he replied and opened their water pouch. He let his arms relax as he let the water flow out, slowly beginning to glow blue. The bite marks were pretty close to Zuko's crotch, Aang realized with a new wave of embarrassment. But actually that didn't matter. He didn't need to touch Zuko in order to heal him.
As the glowing healing water touched Zuko's thigh, he let out a strange yelp and stared at Aang.
The Avatar smiled and continued to focus on the healing. He remembered the first time Katara had healed him, the weird tingling sensation, not quite hot and not quite cold.
"Is this the first time being healed for you?" Aang asked.
"No," Zuko replied, his fingertips tracing the scar on his chest. "The second time."
Aang remembered the brief moment of embarrassment on Zuko's face as he had exposed his scar, and felt bad for him.
"Don't worry. No matter how many scars you have, I think you look great." Monkeyfeathers! Aang cursed in his head. Why did he say 'great'? He meant to say 'fine'!
"Thanks, I guess," Zuko responded in his usually husky, gloomy voice.
Aang's healing water slowly began reaching into the deeper tissues Zuko's leg, and he let the water pulsate slowly.
"That feels…" Zuko began, his voice suddenly more hoarse than usual, but Aang cut him off.
"Please be quiet, I have to concentrate," he insisted. He hadn't done that much healing, and he wanted to get this part right the first time.
After a while of concentrated healing, Aang suddenly saw movement in Zuko's crotch.
"Aang, are you sure you know what you're…" Zuko began, but Aang cut him off again.
"Hush," he insisted, gesturing Zuko to be quiet, "I need to concentrate," he lied. Now that he had the pulsating of the glow down, he didn't actually need to concentrate that much. He casually glanced at Zuko's face, who was staring straight into the night sky, biting his lower lip. So he dared to look at Zuko's crotch again. Could it be that Zuko was having the same problem he had, the same feelings that had been confusing him, causing this stiffening of his privates to happen sometimes?
And indeed, something was stirring in Zuko's pants, slowly causing the fabric to form a tent.
Without intending to, Aang's healing pulses slowly sped up, causing the tent in Zuko's robes to grow even more. He noticed that Zuko's flame was steadily getting brighter, and he could start seeing that Zuko's breath was accelerating.
Aang still stared at Zuko's crotch, mesmerized at the stiff penis that he guessed was underneath the fabric. A small wet spot was starting to form at the top, causing the red silk to darken. Zuko's breath gradually became more erratic, and Aang's gaze wandered to the pale muscular chest, rising and falling under Zuko's panting.
"Ok, stop!" Zuko yelled, extinguishing his flame and quickly backing away in the dim glow of Aangs healing water.
"I'm sorry, did I hurt you?" Aang quickly asked.
"No," Zuko croaked, still panting.
"Then what is it?" Aang was confused.
"I don't want to talk about it," Zuko snapped.
When he returned from the creek where he had washed off the blood and calmed down, he found Aang fast asleep. He had apparently done some earthbending to create a smoother surface to sleep on.
Zuko sighed and lay down next to the avatar, as close as he could without touching him. Then he slowly wrapped his arm around Aang's waist so it wouldn't slide away again when he fell asleep.
Zuko woke up slowly, and with a strangely pleasant feeling. It was almost dawn. He was lying on his back, and someone was hugging him. A head lay heavy on his shoulder, and he could feel a barely noticeable steady breath against his collarbone. He could feel an arm lying lightly on his stomach, rising and falling with every breath he took, and squeezing his waist ever so gently.
With a start, Zuko was wide-awake, realizing who that was. His first impulse was to shove Aang off and run away like he had done before, but a small voice inside him dared him to hesitate. To wait. To enjoy the moment while it lasted.
He hadn't been close like this with anyone in years – Mai had been gone for what felt like forever. But never with a guy. Especially not with a guy. Why was his heart starting to beat faster? Why did Aang's breath against his skin feel so good – so good? He wanted to blame his erection last night on the waterbending healing, but deep down he knew there was more to it. Over the years, Aang had seen him at his worst, but sometimes also at his best, and together they had come a long way. Aang learned to trust him, and that was more than he ever could have hoped for. But this was more than trust and friendship. Aang's tenderness and affection had taken him completely off guard. They had awakened something in Zuko, and he felt as vulnerable as he hadn't felt in a long time.
And as Aang's breath sent tingling shivers down his spine, he could feel his body heating up. Thoughts were creeping into his mind – Thoughts of desire. He tried pushing these thoughts out of his head, but it was no use. Every time he felt Aang's breath, he could feel himself getting warmer and warmer.
"That's ok, Zuko, I'm not that cold…" Aang mumbled in his sleep, feeling Zuko heating up.
"I told you, I'm not your pillow!" Zuko growled, but he didn't make any attempt to shove Aang off.
Aang giggled, and Zuko could feel it against the side of his chest before he heard it.
"You're right. A pillow would be soft and fluffy. You're too… firm" Aang said and started poking his finger up and down Zuko's toned chest.
"Enough," Zuko grumbled and shoved Aang off. "It's not even dawn yet, go back to sleep." He hated to admit how good Aang's fingertips felt against his skin.
"Oh, you have it too!" Aang exclaimed in surprise, now fully awake.
"What?" Zuko asked, sitting up confused, but then he realized. Aang was staring at his crotch, where a boner made his arousal undeniable. As he could feel the heat rise in his cheeks, he realized that Aang had said 'too' – the airbender had a similar tent in his tunic.
"The… your… it's… stiff," Aang stammered.
Zuko's brain was racing.
"Oh, you mean I have morning wood? Whatever…" he tried to casually brush it off and lay back down again.
"What's Morning Wood?" Aang slowly asked.
It slowly dawned on Zuko.
"Did no one ever tell you what…" Zuko gestured at his friend's crotch, "…what it means?"
The airbender shook his head.
"Can I… touch yours?" Aang carefully asked.
"No!" Zuko snapped, "why would you ask me that?"
Aang quickly retreated his hand, and a shadow of sadness crossed his face.
"It's been years now since Katara and Sokka found me in that iceberg, and still there are so many things I haven't caught up on…"
"No, it's not really something that you've missed, it's just…" Zuko began. He tried to imagine being frozen for a hundred years at the age of twelve, then spending the next year roaming the world without parents, training to defeat the most powerful firebender, and ever since being revered as the great Avatar who saved the world from annihilation. He couldn't.
"I'm sorry. It's not your fault no one told you," he apologized.
"So, what is it then?" Aang insisted.
"Uh, I don't think I'm the right person to explain it to you…" Zuko's voice grew hoarse with embarrassment "… It just happens sometimes in the morning…"
"It feels… weird," Aang stated.
Zuko laughed: "Yeah, I guess it does. Now go back to sleep."
As soon as he closed his eyes, he felt Aang snuggle up against him again.
"Aang…"
"Oh, admit it, you don't mind being used as a heating pillow. You just complain like you always do."
"I do mind!" Zuko replied.
"You're lying," Aang laughed.
"What?"
"Toph taught me how to tell when people are lying. It's an earthbending technique," Aang chuckled.
"A technique you apparently haven't mastered yet," Zuko snapped back.
But when Aang didn't respond to that, Zuko didn't shove him off again. He just lay there, stiff and awkward, not daring to acknowledge how good Aang's casual tenderness felt, hoping Aang wouldn't be able to feel his racing heartbeat. He probably could.
"Control your breath. You were doing better yesterday, concentrate!" Zuko told Aang.
"I'm trying!" Aang replied, slowly getting angry. They had been breathing since dawn with no success.
"Okay, let's try something different. Take off your shirt." Zuko instructed. When Aang had jumped out of the top part of his tunic in one swift airbending move, Zuko placed the palm of his hand gently on Aang's chest.
"Assume your stance. Now breathe. Strike the right balance between breathing with your chest and your stomach like we talked about."
As soon as Aang felt Zuko's touch, he knew he would have an even more difficult time concentrating.
"No, no. Feel me," Zuko instructed, shaking off his silk robe and pressing Aang's hands against his chest and stomach. He could feel Zuko's abs and muscled chest expand and contract, and suddenly the idea of running his tongue along Zuko's stomach was all he could think about.
With a fierce roar, Zuko let go of Aang's hand, took a step back, and shot two red bolts of fire out of his fists.
"Like this!"
Then he cringed, extinguished the flames and pressed a hand on his inner thigh.
"I think you missed a bite-mark yesterday…" he muttered.
"I can take a look at it right away!" Aang offered, but Zuko shook his head.
"Not until we make some progress here. Let's try again."
He moved closer again, and they placed their hands on each other's chest and stomach, feeling each other's breath.
Aang couldn't keep quiet any more, he had to say something.
"It's happening again, Zuko."
"What is?" Zuko asked slightly annoyed, his eyes closed in concentration.
"I'm… getting stiff again."
Zuko's eyes flew open: "What? Now?"
"Is that weird? You said it only happens in the morning, but I can't help it…"
"It can also happen at… at other times" Zuko mumbled. He didn't want to get into this conversation right now.
"Like when I healed you, right? You became stiff?"
"No I didn't," Zuko denied.
"You're lying," Aang grinned.
"Okay, I did. So what?" Somehow Aang's casual grin made it easier to admit it.
"Why did you?"
Zuko hesitated. This Truth Seeing was starting to make things difficult.
"Why is this suddenly so important?" He retorted. Asking a question was a good way out.
Aang sighed.
"Because right around the time when it started happening to me, I stopped being able to create fire."
Zuko paused.
"You've never been hard until a couple of months ago?" He tried to read Aang's expression, but failed. He had been shocked at Aang's innocent questions, but he now remembered that Aang was wiser and more powerful than anyone he knew. He was not an innocent boy. He was just inexperienced.
Aang shook his head.
"I see. That's ok," he tried to reassure the airbender whose accelerated heartbeat he could feel at his fingertips.
"So? Why did you – you know – get stiff when I healed you?" Aang insisted.
"Because it felt weird. I'm not used to getting healed, especially not in that… region."
Aang tilted his head.
"Okay, okay. I'll tell you the truth." Zuko took a deep breath: "Because it felt good. Too good."
"I knew it!" Aang cried out with glee, doing one of his airbending-flips of joy. "I knew you liked it!"
Zuko groaned and smacked his forehead.
"Well, I don't think I'm going to get the hang of firebending in the next few hours, so we might as well do another healing session to take care of the bite-mark I missed!" Aang suggested. He gave Zuko a 'you-told-me-you-liked-it-so-why-not?' look, and Zuko sighed, walking over to their sleeping place with the blanket.
Aang examined his thigh through the torn fabric of his pants.
"It looks like everything healed fine yesterday… I wonder if…" Aang muttered, and with a small ripping sound, he tore Zuko's pants a little wider open.
"What are you doing!" Zuko demanded.
"See that's what I thought" Aang said, scratching his head. "I missed this one because I couldn't see it in the darkness yesterday.
As soon as the healing water touched Zuko's skin, he heard him take in a sharp breath. Aang wondered how long it would take Zuko to get stiff again. It didn't take long.
"I take it, it feels good?" Aang teased.
"Shuttup," Zuko barked. "Just get it over with."
"Okay, okay," Aang pretended to concentrate. He was just so curious. Last time it seemed like, Zuko had backed away right before something was about to happen. Now that he knew Zuko enjoyed the healing, he was determined to find out.
As soon as the healing water had reached the deeper tissues, Aang once again began pulsing the glow.
Zuko let out a small gasp.
"Can you slow down? How long is it going to take this time?" he asked, and Aang could tell he was trying to keep his voice steady and casual.
Aang slowed the pace of the pulsing, but unlike the previous night, he now watched Zuko's body with open curiosity, his own cock becoming increasingly hard too. With the wider tear in Zuko's pants, an opening was now there, through which Aang could reach in, if he wanted to.
He increased the pulsing and watched as Zuko's breath became harsher. He waited for the dark wet spot to appear on the fabric of Zuko's pants, and moments later, it did.
"Aang, hurry up, otherwise I'm going to…" Zuko's voice ended in a moan that Zuko barely managed to suppress.
"Otherwise what? Is something bad going to happen?" Aang asked. He didn't understand why Zuko wanted him to stop.
"No…" Zuko pressed out between gritted teeth. "Just hurry up."
Aang's curiosity grew and he sped up even more.
"Does it still feel good?" he asked the now panting Zuko.
At this point, a loud moan escaped the firebender.
"Yes!" Zuko exclaimed.
Aang couldn't restrain himself, so he reached out through the tear and touched Zuko's cock. It felt hot and wet. Soft and hard at the same time. He wrapped his hand around it and pulled it out from under the silk, pulling the foreskin back in the process.
Zuko's head jerked up, and he whimpered in pleasure, looking at Aang with pure surprise and disbelief. At this reaction, Aang repeated the motion, rubbing his hand up and down the shaft.
Suddenly Zuko's body began convulsing. It started with a voiceless gasp, a clenching of his hands, and a bucking of his hips. Then he let out one short moan and shot ropes of white hot liquid onto his stomach. His gasps turned to whimpering and Aang could feel his cock twitching and dripping more white liquid over his fingers.
Their eyes met.
Aang was still holding Zuko's cock, the warm cum on his fingers slowly cooling off. Zuko's body was actually steaming, the sweat instantly evaporating from the firebenders skin. He was panting and staring at Aang with a look that Aang couldn't really read. Surprise. Shock. Confusion, maybe fear, and definitely vulnerability.
"Are you ok?" Aang cautiously asked.
Zuko only stared at him.
The airbender slowly let go of Zuko's cock, and in a moment of curiosity he lifted his fingers to his mouth and licked. It tasted good… salty and with a slightly smoky note.
Zuko's eyes widened.
"You don't have to… you don't… people don't…" he stammered, "…do this," he ended, mumbling to himself.
"It tastes good," Aang shrugged, "What is it?"
"I… I have to go," Zuko muttered, barely managing to get on his feet, and hurrying to the nearby spring, tucking his cock back in, his cum slowly beginning to run down his chest and abs.
