Hello, This is the english version of a fic I wrote a while back and forgot to publish. It's a prompt for a friend and I hope you like it.

Warning: incest, OoC, smut.

X - X - X

After freeing Aang from the iceberg where he was trapped, the siblings Sokka and Katara took him to their tribe, where the young airbender played with the even younger children, having a good time until he destroyed Sokka's "watchtower".

Things got a bit tense after that.

"I'm sorry." Aang apologized to Katara, who just smiled at him. Both teens walking to the siblings' little hut.

"Don't worry, it was a stupid attempt to build a tower." The waterbender reassured him, entering the igloo with the younger boy.

The girl took off her anorak, leaving her dressed in a yukata and pants that highlighted her lithe figure, to the monk's embarrassment and delight.

"Katara, do you have to wear something so thin?" Aang was trying to avert his gaze from the brunette's curvy rear, which was difficult when the girl leaned over, looking for blankets to lend to the Airbender.

"Why shouldn't I?". Katara turned to look at him, raising an eyebrow.

"Don't you get cold?" the bald boy tried to divert his gaze from the pretty girl in front of him, but his eyes betrayed him.

"Not at all." The dark-skinned girl replied, confused by his behavior.

Until she looked down and saw a bulge form in the young man's pants.

"Oh." The girl grinned. "your friend seems to like what it sees." Katara looked at him amused, vainly happy to provoke that reaction in the last airbender.

"I'm sorry!" Aang bowed. "I'll just leave." Aang completely embarrassed tried to run away…

Until he froze when the girl began to massage his bulge.

"There's no need". The girl felt her pussy get wet when she saw Aang's cute reaction.

Her hand unconsciously touching the young man's cock barely contained by his pants.

"I think there's something you can do for me." Pulling down the pants of the overwhelmed bald boy, the girl was pleasantly surprised by the size of the teenager prick. "Darn, it's quite big." Katara thought excitedly.

"Guahh". The Airbender gasped as the girl pushes him, landing on his butt. "Katara!" The young man squirmed when the young woman got on all fours and began to suck his cock, all while her blue eyes stared at him. "It feels so good!"

"Mmm". The black-haired woman just kept giving him oral pleasure, her mouth moving back and forth, taking his whole length with ease.

The girl had only been with one person, so she didn't have much experience, but the boy was so horny that they basically did it every day, so she got used to have a cock in her mouth.

The horny boy she was thinking about suddenly entered the igloo, being surprised to see his sister sucking the cock of the boy they found on the iceberg.

Both teens didn't notice his presence, immersed in what they were doing.

"What the hell." Sokka thought angrily, preparing to berate them, until the sight of his sister's toned ass made him rethink his approach.

There's a better way to make them know he is there.

Approaching the pair silently, the wannabe swordsman dropped his pants and the brunette's rear…

…hard.

"Ahhh!" Katara arched her back, stopping the blowjob Aang was enjoying. "Fucking bastard!" She turned her gaze to glare at her brother. "Why do you have to be so rough?"

"Sokka?" Aang looked surprised to see the siblings interact like this, and to see Sokka jerking off while pulling down his sister's pants. "Is this…normal?"

"Sure". The older boy massaged the brunette's buttocks, sticking a finger in her tight anus, eliciting a moan from Katara. "Why do you think she's such a good cocksucker?"

Without waiting for an answer, the ponytail boy slammed his cock into his sister's tight asshole.

"Ooohhh!" Katara screamed in surprise. "Slower you idiot." Katara complained to her brother, moving her hips a little to get used to the feeling of having a thick cock in her ass, while jerking off Aang's cock. Sokka just laughed and spanked her, slowly swaying back and forth, getting used to the tightness around his dick.

"You complain but look how much your ass squeezes my cock." The boy from the water tribe didn't let her quip back, increasing the speed of his thrusts. "Poor Aang, having to see you act like the whore you are."

"Don't be a douche". Katara stopped masturbating the gaping avatar and, while still getting fucked from the rear, she arched her back and took off her top garment, showing her dark-skinned body to the excited guys. "Surely Aang doesn't mind, right?" The girl smiled at the monk, while massaging his balls.

"No-nope, no problem.". Aang groaned when Katara started to suck his cock again, looking up and grinning stupidly when he felt the young woman's tongue lick the tip of his penis.

The situation was too exciting for the girl, moving between two hard cocks, her mouth and ass being fucked without delicacy at all. The waterbender began to squeeze her clit with her left hand, rubbing her labia rapidly.

"Do you like it in the ass, you dirty slut!?" Sokka shifted his position, leaning his chest on her slender back, his cock sinking into her tight anus all the way to the base. "Do you like having your big brother inside of you?" The boy pulled her away from the avatar, grabbing her right tit with one hand and squeezing her neck with the other.

"Yes, I fricking love it!" Katara's voice increased in volume as her brother tightened his grip. "I love having you on my ass." The siblings were lost in their world, enjoying the forbidden pleasure they are getting so used to doing.

Aang masturbated like crazy, his hand a blur matching the pace Sokka was doing his sister's backside, while staring at Katara perky tits bouncing wildly, one barely contained by the older boy's hand.

"By the spirits, my ass feels great!" Katara rolled her hips against her brother's crotch, gasping when the young man increased his pace even more.

"It totally does." Sokka wouldn't stop moving, loving the tightness of his sister's butt, as he noticed the monk jerk off. "Hey, why don't you let Aang taste your ass?" The boy smirked. "He needs to feel an ass after being frozen on that glacier."

"Good idea". Giving her brother a short kiss, the girl pulled out the cock off her ass, the waterbender gesturing for the young monk to come closer. "Come here Aang."

The avatar, not that the southern tribe's teens knew that, rushed coming face to face with Sokka, the hot girl between them, manipulating water on their hard cocks, which trembled from the cold contact.

"You guys are really excited." The brunette began to kiss the monk, who despite his inexperience, make up for it with his enthusiasm. "Sokka, use your hands for something useful for once."

"Damn, you're haughty today Katara." The 'swordsman' obeyed instantly, massaging the young woman's perky breasts, her nipples hard from cold and arousal. "Do you want to impress someone?" The girl's hands moved quickly, masturbating both pricks.

"I'm just showing Aang the hospitality of the southern tribe." The girl moved away from the boys to lie on the bed, sticking two fingers in her wet cunt. "Now Aang, why don't you stick that cock in my little anus?"

"really?" - Aang's eyes sparkled when Katara winked at him and spread her legs, her holes in view of the airbender.

"Just be careful, not like this idiot." The girl mock glared at her brother who just smirked and approached her, his cock raised like a flag against the wind.

"No idea what you mean, little sis." The brunette slapped his sister's cheeks with his thick cock. "I mean, you like a river down there." The waterbender just rolled her eyes and turned her head, opening her mouth to suck on her brother's penis.

"Mmmmhhh!" The attractive young woman moaned on her brother's cock as she felt the monk slowly insert his cock into her sensitive ass, his balls hitting Katara's firm buttocks. "Mmmhh...shit, you feel so good in my ass Aang." Stopping sucking on her brother, the young woman encouraged the young Airbender, who just smiled and started to move.

"Hey, don't forget what you were doing." The older boy, annoyed by the attention the girl was paying to the the other boy, began to thrust Katara's face from the side, his cock hitting the girl's cheek with each strong thrust from Sokka. "Use that mouth for something more than talking."

"Katara..." The avatar gritted his teeth as he resists the urge to cum, grabbing the girl's hips and moving his pelvis like crazy, his cock going in and out of the pretty girl's tight hole.

"Ahhh, you're doing great Aang, keep going." Katara moaned like crazy, being treated like a cheap woman. But the girl was determined to try something her mother told her she used to do on her meetings with Bato and Katara's father. "I want you both at the same time." Both boys stopped thrusting in surprise at her statement.

"I don't know Katara, that sounds very gay." Sokka complained, not at all excited about the idea.

"If Katara wants it, sure." Aang for his part would do whatever the older girl told him to, in order to continue having sex with the attractive older waterbender.

"Good Guy". Katara straightened up to kiss Aang, then pulled away and lied on her side on the bed. "Now take my ass again."

"Katara, I'm not gonna do this, I'm a grown man." Sokka kept complaining, annoying his less 'mature' sister.

"Leave your stupid machismo asi-DE!" The girl's reprimand was interrupted by the sudden invasion of Aang's cock into her butt, the enthusiastic young man grinding his pelvis against the girl's toned asscheeks. "Don't tell me you're not a real man."

In the end, the waterbender resorted to the perfect way to convince her headstrong brother to do something, to judge his manhood.

"I am!". Sokka fell for the trick, laying down in front of his sister, cock in hand. "And I'm going to show you." The brunette rubbed his sister's vagina with his cock.

"Well, do it, brother!". The young woman screamed when the swordsman plunged his cock into her wet pussy, only separated by a thin membrane of the cock drilling into her ass. "Fuck... two cocks…at the same time..."

"Shit, you're tighter than usual..." The young man thrusted hard, listening to Katara's moans with satisfaction. "But my cock is what makes you scream like a whore."

"Katara, do you like my penis in your butt?" The avatar was not far behind, his thrusts plunging his cock into that tight anus, while squeezing one of the firm breasts of the young woman.

Katara was in her own world, overwhelmed with pleasure, so she didn't answer to any of them.

"What are you talking about Aang?" Sokka berated him, ego in the clouds. "Your little dick is just a side thing for my cannon."

"That's not true!" The teenager wasn't intimidated by the older boy. "Katara loves my penis, I can feel her ass sucking on it, wanting more!"

"I'm the one setting the pace." The brunette slapped his sister harshly, making her slowly come to her senses. "If Katara is enjoying it, it's because I'm fucking her pussy!"

"Both of you are great". Katara screamed at the top of her lungs, her holes squeezing their cocks like a glove as the girl orgasmed, moving her hips in synch with her boys' movements.

That stopped the idiots from their dick measuring, feeling the woman squeeze them tightly.

"Katara, I'm going to cum." The bald guy gritted his teeth as he stopped fucking her ass, wanting to pull out.

"Come inside." She said, sighing happily when she felt Aang's cum fill her insides, his cock shaking on her ass. A line of cum dripping from her hole when Aang removed his penis from her abused asshole, the young man falling exhausted on the blankets.

"Gonna cum too.". The brunette wanted to hold out more, but his sister's pussy felt too good.

"Sokka!?" Katara exclaimed in surprise when her brother came out of her pussyy flipping her over and ramming into her really sensitive ass. "Ohhh, damn it I told you, not so rough!"

The brunette ignored her, his member sinking lower and lower with each thrust, ignoring the sensation of Aang's cum on his cock. The waterbender stayed still and only endured the young man ramming into her abused hole.

"I'm going to fill your ass!" Sokka said in her ear, the siblings staring at each other, Katara's mouth emitting a silent scream as her brother fulfilled his promise, painting her anus with white.

Coming out of the girl's butt, Sokka fell onto the blankets next to Aang, both boys bumping fists, no energy left.

"I hope you still have more energy." The tribe member girl's blue eyes sparkled with lust, her body covered in sweat giving an erotic glow to the girl, who crawled over to the boys. "I'm not satisfied yet." The black-haired woman felt a morbid pleasure when she feels the boys' cum fall down her legs. "Noy, I need both of you in my pussy"

"Sure!". Aang felt his energies magically return, the young man living the fantasy of all teens of fucking an older girl, especially someone as cute as Katara.

"You're really slutty today." Sokka stayed on the bed, feeling his prick stiffen. He was not going to lag behind the airbender. "Very well, what do you want me to do?"

"Just stay there." Katara grabs the younger boy's face and brought it to her firm breasts, the monk enthusiastically sucking on the girl's nipples. "I'll take care of everything."

Leading her young lover to her brother's, Katara guides the Airbender to the front of Sokka. "Aang, cross your legs with his."

Aang obeyed, lying in front of Sokka, the boys lying cross-legged.

"This is weird." Sokka complained, uncomfortable with having Aang's balls touch his.

"Don't be a baby." Using the water in the hut, the waterbender got the cocks wet, cleaning them and leaving them lubricated for what she wants to do.

Straddling the boys while facing Aang, Katara grabbed both cocks firmly with one hand, her lower lips touching the tips of those hard cocks. "Here we go". The young woman thought nervously, but extremely excited.

"Ahhh!" The three young teens couldn't suppress a cry of pain mixed with pleasure when the brunette fell on the hard cocks of her boys, her vagina receiving both penises to the hill. "It hurts! Fuck it does! but it feels… ahh… it feels so good!"

"It's so tight!". The black-haired woman heard one of the boys say that, not knowing which one, after she lost consciousness for a second. The boys held her by the hips, making her bounce off their pricks.

"You're going to ruin my pussy." The brunette had her tongue sticking out of her mouth, her hands squeezing her breasts. "Fuck, my cunt is full of two cocks!"

Neither of the boys responded, concentrating on ramming into the womanhood of the beautiful girl, who was beginning to bounce on her own.

"You're a slut Katara, the biggest one ever!" The brunette told her slapping her firm buttocks, which were shaken by the bounces of the waterbender.

"Don't push it.". Katara began to shake her hips, moaning every time one of the cocks hit her g-spot. Letting out a squeak when she felt the airbender squeeze her clit, the blue-eyed grinned at the young monk. "Good, you're learning".

"Katara I…I". The Airbender tried to say between gasps, staring at the young woman's breasts bouncing with each abrupt movement the young woman made to feel more of the cocks in her vagina. "I am going to cum."

"Me too." Sokka's gasps joined Aang's, both young men thrusting in unison into the waterbender's pussy, and with a heavy thrust both hit her uterus.

"Shit, shit, shit!" The young woman suffered the biggest orgasm of her life, her fluids wetting the pelvises of the boys, who couldn't take it anymore.

"...!" The brunette could only feel how two cumshots of milk flooded her pussy, the boys remaining inert on the blankets, their cocks softening after such an intense session.

"Muahhh". The girl lets out a groan as she pulls the cocks out of her sensitive cunt, a great amount of cum dripping from the act, her legs shaking from the effort.

Katara grinned.

"Thank you so much guys". The brunette's surprised when she didn't hear an answer. "Guys?"

Seeing her boys unconscious, the waterbender could only giggle and wonder…

When they could do it again.

"Maybe tomorrow." Katara thought as she lifted Aang's light body and placed him next to Sokka, falling between them and looking at the adorable face of the monk. "It won't be difficult to convince them." The brunette giggled a little when she felt her brother's hands squeeze her breasts and those of the avatar looking for her buttocks.

Tomorrow will be a great day.

X – X – X

It's been a long time since the Gaang first had their first threesome in the southern tribe. After Prince Zuko attacked them, looking for the avatar, the group traveled the world until they reached the northern water tribe, for Aang to learn to master Water-bending.

After encountering culture shock between the tribes, the boys resorted to the best way they could to de-stress.

"Mmmhh!"

Upon arriving at the small house that the northern tribe let them use, an annoyed Sokka entered the shared room, seeing his little sister on her knees and her mouth being roughly fucked by an Aang with his pants down, who surprisingly had a frown on his normally dopey face, scowling as he grabbed Katara's head and shook it back and forth on his cock.

"Hell, what did Katara do today, Aang?" The wannabe swordsman's surprised to see his friend abuse the waterbender's mouth in this way, his balls hitting the brunette's chin with each thrust. Just the sight of her naked sister frantically sticking two fingers into her wet pussy made the older boy see that the girl was enjoying being treated like this.

"Katara complained to Master Pakku, again, of the male hierarchy the tribe has." Aang let go of his friend's head, who took the opportunity to breathe, a pop echoing as she stopped sucking on Aang's cock.

"That man continues to talk about his chauvinistic views." Her soft hand was jerking off the avatar, who had finished taking off his shirt and pants. "That a girl has to be submissive and follow stupid traditions." Giving small licks to the tip of the prick in her hand, the girl kept complaining.

"Yeah, tell me about it." Sokka said remembering Princess Yui's excuses for not having a relationship with him. "Here the girls're too prudish."

Sokka quickly took off his clothes and walked over to the younger teens, bumping fists with Aang and showing his hard cock to his little sister, who just rolled her eyes and started to jerk him off too, her hands moving in unison, demonstrating her experience in handling both boys at once.

"Well." Aang let out a groan when Katara began to massage his balls, while sucking on the tip of his dick. "Katara's kinda right."

"But being the know-it-all that she is, she couldn't keep quiet." The brunette grabbed his sister's head, turning it to bury his cock in her warm throat. "We're outsiders, they give a crap about our opinion." Sokka felt his legs go limp when the waterbender gave his cock little licks, even with it inside her mouth.

"Muahhh...". Katara stopped sucking her silly brother cock to look at the boys. "This tribe is backwater compared to any other place."

"Maybe you shouldn't talk so much." Aang gave the idea to his friend, while crossing glances with the older teen who nodded, having the same idea.

"We can help with that." Sokka smiled wickedly.

"What do you mea-". Katara was interrupted when both boys came together and the tips of their cock touched her full lips, trying to enter at the same time. The girl opened her mouth from the surprise and her eyes widened when the guys plunge their penises into her throat, starting to fuck her mouth erratically, trying to find a rhythm that suits them.

"You've to learn to keep quiet little sister." The boys ignored their cocks touching each other, and Katara's complaints as they took turns ramming the young woman's oral cavity. "We're going to help you learn how to do it."

"Yeah Katara." The avatar nodded. "Maybe if you do this to Master Pakku he would let you train with the group."

"Mmmhh!" Katara was trying to catch her breath, something difficult when she felt the hands of the boys hold her head firmly. Her teenage pussy wetting the floor with her fluids, drool fell from her mouth, full of hard cocks that she licked without energy.

"Ahhh, shit, I'm gonna cum." Sokka started to move more frantically, Aang keeping up with him, both boys burying their cocks down the waterbender's throat. "Swallow all of it Katara." The young man begins to fill his sister's mouth with his cum, who began to cough and stop sucking on both cocks.

"Katara!" The avatar masturbated a couple of times and started to cum on her friend's face, his cum bathing the face and hair of the only girl in the Gaang.

"Ahhh." Katara swallowed what she could of Sokka's cum, the rest falling onto her perky breasts, the creamy milk gathering with the Airbender's. "You really have to be gentler guys."

Showing her slender body covered in milk, her dark complexion painted white, the girl looked with excitement at her boys, still hard as rock.

"You won't be able to move tomorrow." Sokka promised her, his friend nodding.

"All bark no bite." The girl was eager to see if they would back the talk up.
