Aang and Sokka sat by the fire, Sokka eating a bowl of stew that they made earlier, while Aang just stared down at the fire. The Avatar had a pensive look on his face while he poked the flame in front of them.
It took his friend a bit before he decided to strike up a conversation. “You doing alright?” Sokka asked, setting his bowl on his lap.
Aang hummed as he turned up at the other, “Oh, yeah I’m fine. Just wondering about where Katara and Toph are.” He turned to the forest nearby. “They’ve been gone for a while, longer than usual for them to just grab some firewood.”
“Eh, I wouldn’t worry about it. They can take care of themselves. I’m sure they’re just having some much-needed girl time.” Sokka assured before taking another bite of his stew.
It wouldn’t be long before a rock would fly towards his head, almost hitting him if not for Aang’s quick reflexes and bending a rock wall to protect him. A shrill squeal left Sokka as he got to his feet, grabbing his boomerang defensively.
As the two of them stood ready for confrontation, they could hear the sound of distant yelling coming closer. The closer it got, the more they began recognizing their voices.
“You never take anything seriously!” Katara spat.
“Yeah? Well at least I know how to relax and not keep a stick up my ass!” retorted Toph, their bickering getting closer until they were finally within sight of Sokka and Aang.
Sokka relaxed, dropping his boomerang to the ground. “Thank the spirits, it’s just you…two…” He trailed off when he watched Katara march past him and crawl into her tent. She had a very disgruntled look on her face as she huffed inside.
Turning back to Toph, the young girl sat in front of the fire with a groan. Her arms crossed and she faced the burning flame in front of her. Her teeth gritted in a scowl, foot tapping impatiently.
Aang looked between Katara’s tent and where Toph was sitting. Not one to see his friends upset, he wanted to figure out what was wrong.
“…Did something happen?” Aang asked.
“No. Just miss hard ass being her usual self.” Toph snipped, not even looking in Aang’s direction. “Gotta suck the fun out of everything.” She kicked a small pebble in front of her into the fire.
Sokka then turned to the tent Katara was in, deciding to try and do his part as well. He approached the tent slowly and quietly before peeking inside.
He saw Katara lying on her side with her back to the entrance of her tent. He remained quiet for a few seconds before speaking up.
“Hey…you alright?” He asked, but got no response. He waited a moment before he decided to crawl into her tent fully.
“You uh…wanna talk about what happened with you two?”
“No.” Katara said tersely, still looking away.
Sokka remained quiet for a few seconds before clearing his throat. “Alrighty, well, if you need me I’ll just uh…be in my tent.” He started crawling backwards out of the tent, stopping when he heard his sister speak.
“Do you think I’m boring, Sokka?”
He turned back to Katara, staring before crawling back inside. “What? No, no of course not! I don’t think you’re boring.” He insisted, though he couldn’t quite hide his honesty. “…usually.”
A groan left Katara, tensing up before finally rolling around to face her older brother. “I knew it. I try to make sure everything is going smoothly, and everyone just thinks I’m some kind of uptight jerk.”
“Sis, no one’s saying that.” Sokka insisted, scooting closer to rest a hand on her back. He lightly caressed her, eyes fully on the young woman.
“Toph did.” She retorted, rolling her eyes. “I tried to make sure we got back before sundown, but she had to go and mess around and get us lost.”
“Katara, I’m sure she didn’t mean it.” Sokka replied, feeling Katara start to relax.
“Sure, but we could have been here way sooner if she didn’t keep acting like a kid.”
“She is a kid, sis.” He replied, earning a terse look from Katara that soon started to soften.
She let out a groan, looking back at the floor. “I know, I know. I just…I don’t want us to be in a bad spot, ya know? Between helping out you and Aang and making sure Toph is alright, it’s a lot to deal with.”
Sokka took a deep breath, resting his hand on the middle of her back. “Sis, you’re putting way too much on your shoulders here. We’re very grateful for what you’ve done for us, but we can handle ourselves too.” He gave her shoulder an assuring squeeze.
Katara let out a hum as she relaxed against her brother’s touch. “I don’t want anything to happen to us.”
“It won’t. Not as long as we’re together.” He assured with a grin and a nod. “You do so much for us, and I don’t think that’s boring at all.”
Katara couldn’t help but chuckle, a smile now on her face. She then got up to her knees, resting her head on her brother’s shoulder.
“Thanks, Sokka. You’re not boring either.”
“Course not. I’m never boring.” He insisted with a proud grin.
“I dunno, you can go on about certain weapons a bit too long.” Katara teased, giving his side a playful shove.
“Weapons are never boring!” He insisted, shoving her back. The two of them let out a few more giggles, enjoying the other’s company.
“Alright, well if you’re felling better, I’ll-“ Sokka leaned forward towards the entrance of the tent, attempting to leave before realizing that Katara had her arm around his waist. He turned back to his sister, watching as she then crawled onto his lap, straddling his waist.
His heart skipped a beat and he could feel his face start to flush red. “Uhhh, Katara?...” He trailed off with a slight squeak in his voice.
“It’s been a while since we’ve had our ‘special fun’, hasn’t it?~” Katara whispered into his ear, a smile on her face.
A soft gasp left Sokka, now starting to feel Katara start grinding against him. “S-Sis!” He whispered loudly, “Aang and Toph are right outside.” He pointed in the direction of the campfire just a few feet away.
“Come on, we just gotta keep quiet.” Katara persuaded, “Besides, I know you want it too. I’ve seen you checking me out when we’re in the water~” She teased, leaning down to press her lips to his neck in a kiss.
Sokka bit his lip to muffle a moan, unable to hide his arousal from the young woman. He found himself starting to arch against her grinding, getting harder by the second.
“I need a real, Water Tribe cock inside me right now~” Katara exhaled, “And you’re the best one I’ve ever had~” At that point, she had gotten Sokka on his back, her chest pressed against his.
She then pressed her lips to his in a deep, loving kiss. Both of them groaned in response, the other kissing back while their hands explored their bodies. Katara’s hands had slipped inside Sokka’s outfit, feeling his chest. Sokka’s hands were on Katara’s thighs, traveling up to her waist.
Katara then started taking off Sokka’s outfit, first removing his robe and setting it aside before pulling off his shirt. Her hands eagerly traveled along his chest, her thumb playing with one of his nipples. She knew how much he loved that.
A low moan left Sokka when he felt his sister touch him, his own hands now making quick work of Katara’s clothes. He tossed her robe aside before undoing her undergarments, revealing her breasts to him.
One of his hands reached down to start groping and massaging before he pulled his lips away from hers. As soon as he did, he leaned down to start suckling her other breast, tongue eagerly circling her nipple.
Katara bit her lip tight, muffling herself as best she could while her brother suckled her chest. Her free hand rested on the back of his head, pulling him closer while she continued to grind against him.
At this point, Sokka was at full mast, but still confined to his clothes. But he was much more absorbed in tasting his sister than in what he had between his legs. A pleased hum left him, his free hand now keeping a firm grip on Katara’s rear.
“S-Sokka…” She trailed off, starting to get too worked up. After a few more seconds of letting her older brother sample her chest, she pulled herself away from him with a groan.
Sokka stared up at Katara, a dumbfounded look on his face. He then watched as she lifted herself off him and took off the rest of her clothes, setting them aside and leaving her fully naked.
“Wouldn’t you have something more sweet?~” She hummed, reaching down to spread her slick lower lips to the young man. She kept her legs spread, noting the hungry look on the other’s face.
“You know me too well~” He whispered, crawling closer before hovering his mouth in front of her sex. After a moment of admiration, Sokka cupped the back of his sister’s thighs and pulled her closer before eagerly eating her out.
“Haah!-“ Katara cried out before quickly covering her mouth with her hand. She shot her head in the direction of where Aang and Toph were, hoping that by some miracle they hadn’t heard them.
“Katara? Are you okay?” Aang’s voice chimed from the campfire a few feet away.
“Y-Yeah, I’m fine!” Katara assured, trying her best to sound unfazed.
“What happened?” The Avatar asked.
She struggled with an answer for a bit, mostly because Sokka hadn’t stopped eating her out since he started. “Uhh, I-I just got a cramp! I’m good now, though. Sokka’s helping me with it.” She looked down at Sokka, shooting him a glare that didn’t faze him.
“Oh, alright. Let us know if you need anything.”
“Thanks!” Katara called out before turning back to her brother.
“You couldn’t have stopped or anything?” She whispered between sudden jolts and whimpers.
Sokka finally pulled his mouth away, “Didn’t you say that all we needed to do was keep quiet?” He asked with a smirk before going back to eating her out.
“You-mmm!~” Katara groaned, keeping her lips pressed tightly together. She reached a hand down to grab the back of his head, gripping his hair and keeping him pulled close to her sex. The longer he kept going, the more intense his licks started to get.
Her free hand then moved to her breast, playing with her nipple as she continued arching and grinding herself against her brother’s face. She could see him buck his own hips against the floor of the tent, no doubt getting eager to get his own rocks off.
Sokka’s tongue brushed and lapped against her dripping cunt in the best and most wonderful ways. Ways that only Sokka knew would drive Katara crazy. If only their friends weren’t so close, then she could really let him know just how much she loved the things his mouth could do.
Her nails started digging into his scalp, a low snarl of pleasure leaving her lips. “Sokkaaaa, I’m getting close~” She hissed, her legs now starting to wrap around his head.
As soon as she said that, she felt the other start licking faster, somehow. She couldn’t help but start rutting desperately against his face, her teeth the only barrier keeping her moans from penetrating the walls of the tent and into the night sky. Ever flick of his tongue sent a jolt of pure bliss through her body.
It finally culminated in one hot, wet, intense moment of pleasure. Katara made sure to keep Sokka’s face firmly lodged against her as she came, slick squirting onto his lips while her body arched forward. She was completely stiff as she came, shuddering with ecstasy. Her teeth gritted tightly in her mouth, sweat trailing down her dark skin while slick trailed down her brother’s throat.
Sokka happily swallowed all of what his sister provided, a pleased hum leaving him. The beautiful, erotic sting of her nails and the comforting crush of her thighs nearly sent the young man over the edge himself.
The two of them remained locked there for a few moments before Katara finally released her hold on him. She went limp in the tent, laying on her back and staring up at the ceiling. She could feel him give her lower lips a few more licks before pulling away. She couldn’t even muster the energy to look up at him.
Lucky for her, she didn’t need to. Sokka crawled up so his face was right next to hers. He had a smile on his lips, eyes locked onto his sister.
“Did ya like that?” he asked, brushing a hand down her waist, cupping her buttock. He couldn’t help but steal a quick kiss from her as she turned towards him.
Katara took a moment to catch her breath, lips curled in a grin.
“You…Your mouth is magic~” She exhaled before kissing him back.
The two laid on the floor of the tent together, arms wrapped around each other while their tongues explored their mouths.
Pleased hums left both of them, their bodies arching and grinding together. Katara ran her nails lightly down her brother’s arm while Sokka kept a firm grip on his sister’s waist. The whole time, he could feel himself continue twitching and aching in his pants.
He didn’t need to worry about that for too long before Katara reached her hand down to take his pants off. She felt his cock pop out and lightly smack her palm, earning a muffled chuckle. Wrapping her fingers around him, she slowly started stroking him.
“Mmm!~” Sokka hummed against the other’s lips, hips now arching towards her strokes. Pre dribbled from his tip and onto the other’s hand, providing adequate lube.
He pulled his lips away from her, now staring into her eyes. “Ka…tara~” He moaned, squeezing her hips as he felt her strokes.
She couldn’t help but smile, always happy to see him so blissed out like this. Her thumb played against his dripping cock slit, making him tense up and jolt in surprise. A soft chuckle left her before she started kissing his neck again.
Pleasured grunts and whimpers left Sokka, his body jolting every time his sister did something new. He was starting to get a tad impatient, however.
“Katara…please…” he whined, eyes squinted and teeth gritted.
Katara muffled a chuckle, pulling her hand away from his twitching, dripping cock. She then suddenly pushed Sokka on his back, prompting a gasp from the young man.
Straddling his waist, Katara started rubbing her bare cunt against his hard cock. The feeling of his hard member pressed against her entrance prompted soft moans from both of them. She gripped his shoulders tight, staring down at his flushed expression.
Sokka’s grip on the other’s waist tightened as he felt her start to lower herself down on him. Gritting his teeth, Sokka’s tip penetrated Katara’s lower lips, the rest of him slowly following.
A shrill moan left Katara, feeling more of her brother push inside her. Her nails dug into his shoulders, body tensing for a moment before she forced it to try and relax. Every time she felt him, she needed a moment to get used to his size again.
“A-Are you okay?” Sokka exhaled, watching Katara gasping hotly and whimper as she pushed herself further down.
“I’m fine, I’m very fine~” She assured before she finally got all the way down, taking his whole length inside her. Her gaze then moved from his chest back to his face, she had a smile on as she started to lift her hips up before slamming back down.
Sokka bit his lip to muffle a moan, his cock twitching and dripping inside her. He felt her slam back down again, prompting another pleasured growl. He kept a firm grip on her waist, arching up towards Katara when she pushed herself down.
It wasn’t long before she got into a rhythm of bouncing on his dick, letting out pleasured noises of her own. As she moved her body, sweat started to trail down her form, giving the young woman a seductive sheen. Her breasts bounced ever so slightly from the movement, no doubt the sight of it was nothing short of awe-inspiring for her brother.
Sokka couldn’t turn his eyes away from his sister, taken aback by just how beautiful and sexy she looked right now. He bucked his hips in time with her slams, which were steadily starting to pick up in speed and intensity.
“Sokka~” Katara moaned, her body starting to arch forward so her chest was inches above his. She stared down at him with a grin, clutching onto his shoulders tightly.
“You feel amazing~” She exhaled, her hot breaths tickling his cheeks.
“So do you, sis~” He replied, one of his hands traveling up to cup her cheek. “Never had anyone as great as you~”
“And you never will, I bet~” Katara teased, one of her hands running down his chest again. In the next moment, she leaned her face down so her mouth was pressed against his nipple. She started trailing her tongue along the pert flesh, relishing the flushed squeaks he made when she did.
“Ohhh, spirits!~” Sokka grunted, bucking harshly in response to his sister suddenly licking his nipple. Her nails dug into her soft hips, cock throbbing faster inside her. It wouldn’t be long before he was about to blow.
Pleased with his reaction, Katara gave Sokka’s nipple a light bite before pulling away. A chuckle left her as she sat back up once more, starting to bounce faster as well.
“Sokka~ Please, fill me up~” She practically begged, her voice shrill and hoarse. Her eyes slammed shut as she kept riding him, wanting nothing more than to feel him inside her.
“K…Katara…!~” He grunted, trying to warn her that he was about to finish. However, he had reached climax before he had the chance to.
His teeth gritted tightly while he bucked hard inside her, tip erupting with seed that filled her womb in a near instant. He continued to clutch tightly to her, making sure she couldn’t pull away.
Katara came as well, her sex tightening around Sokka’s length. She had to muffle her moans against her brother’s shoulder, latching onto him for dear life. Ever throb of his cock and rope of seed shot into her made her body shudder in arousal. Whimpers of pure bliss and ecstasy left her, silenced by her brother’s toned, sweaty shoulder.
The two of them laid together on the floor, arms still wrapped around each other. Tired breaths left both of them, eyes closed while keeping the other close to them.
Sokka cracked his eyes open, looking down at his tired, sweaty, beautiful sister. He ran his hand along her back, caressing her while taking in the sight of her.
“Spirits, Katara…you know how to have fun~” He exhaled.
She smiled at his praise, lifting her head up to lock eyes with him. “That’s right, I do~” She then pressed her lips to his once more, kissing him deeply. It wouldn’t be long before they both fell asleep in each other’s arms.
The next morning soon arrived, everyone quickly packing up everything before they started traveling again. Aang was getting Appa hitched up while Sokka and Katara were getting dressed in her tent.
Once they were decent, Katara peeked out to make sure no one was outside. When the coast was clear, she quietly instructed Sokka to hop outside and back to his tent.
The young man quickly hobbled out of the tent and back to his own, hoping to try and give the illusion that he hadn’t slept with his sister.
Katara watched him leave before she stepped out of her tent. Clearing her throat, she made her way to their bags to try and find something to eat.
“Hey, Katara.” Toph spoke up, making Katara jump in surprise, shooting towards the young girl that seemed to have sprouted behind her.
“Oh…morning, Toph.” She greeted, noting the pensive look on the other’s face.
Toph looked to the side, rubbing the back of her head before taking a deep breath. “I…wanted to say I’m sorry for how I acted yesterday. I didn’t mean to get you all mad or anything or make you think I wasn’t taking you seriously.” She apologized.
Katara’s brows lifted in surprise, honestly not expecting an apology from Toph so soon. But she also knew that what happened wasn’t entirely her fault.
“Thank you, Toph. And I’m sorry for overreacting. I didn’t mean to make you mad or anything. I know I can be a bit uptight sometimes.” Katara responded, her words making Toph smile a bit.
“Eh, it’s all good.” She assured before delivering a light punch to her shoulder.
Katara grunted in surprise, but she knew Toph didn’t mean anything bad by it. “Thanks. I’ll try not to be so wound up.”
“Yeah.” Toph nodded, her hands behind her head.
“Maybe if you could be half as loose as you were with Sokka last night.” She shot Katara a knowing grin.
The older girl’s eyes widened, face going pale and her heartrate suddenly skyrocketing. Dammit, of course she would know what they were doing.
“T-Toph, please, it’s not what-“
“Relax, princess, I’m not gonna tell anyone what you and your brother get up to. I’m not that sloppy. Just thought I should let you know that you two aren’t as sneaky as you think. I mean, I had to pull Twinkletoes back to keep him from finding out. You’re welcome.” She nudged the speechless water bender.
“Alright, so where we headin’ to today?” Toph asked before she made her way towards Aang and Appa.
Katara just stared blankly at the young girl, her face burning bright red. She didn’t notice Sokka walking up to her.
“Hey. You alright?” Sokka asked, a bag over his shoulder.
Katara then snapped out of her daze, “Y-Yeah, I’m fine. Let’s get ready to go.” And like that, she was back to packing for the day ahead.
