Okay, this was not exactly what I had planned when I set out to write this chapter, but this version was more fun than the one I initially thought of. One of the lines of dialogue was inspired by something an apparently real person said on TikTok, and I just HAD to include it in this story somewhere. Bonus points if anyone can guess which one it is. Anyway, you guys know the deal. Thoughts and comments always welcome, and hope you enjoy.

As the rest of his friends filtered into the apartment, Zuko felt the distinctive pressure of Azula grinding herself against his lap, his length springing nearly to full length inside of her despite the tension apparent in the apartment.

"Could you guys like get decent so we can talk?" Katara asked, shifting her narrowed eyes away from the scene unfolding in front of her.

"Something tells me there won't be much talking on our part," Azula drawled, her fingertips burrowing into the cushioning on the back of the sofa as she pushed herself insistently down onto Zuko's throbbing erection. Biting down on her lower lip, she made sure the group's collective attention was focused squarely on her as she rolled her hips back and forth atop his lap, a distinctive thrill surging in her loins at having an audience.

"Uh, Zula, maybe we should give it a rest for a bit," Zuko said between groans, the heat from his sister's honeypot making clear thinking extremely difficult.

"Oh, such a worrywart. They don't all seem to be against it," she replied in a teasing tone, her eyes focusing on her long time friend. Ty Lee's eyes looked like she had seen something extremely enjoyable, her knees subtly shifting in time with the pressing of her legs together.

"Ty Lee are you okay?" Sokka asked, quirking an eyebrow up in mild concern as he followed Azula's gaze to the bubbly brunette.

"Yeah, she's fine, she's just really turned on right now," Mai said flatly, a heavy sigh escaping her lips. "But seriously, Ty, could you cool it for like five minutes?" she asked, a flare of annoyance and jealousy sparking across her features.

"Sorry, but it's just so… hot," Ty Lee responded simply, earning groans of disapproval from the unoffending siblings and Suki.

"You've never been this hot for me before," Mai retorted, her voice taking a rare spike to a higher volume as she felt a pressure beginning to squeeze her chest.

"Aww, babe, it's not like that," Ty Lee whined, throwing her arms around her perpetually somber girlfriend.

"Then what IS it like?" Mai turned her gaze directly towards her lover, amber spheres narrowing as she listened for an answer.

"It's just the whole surprise aspect of it, ya know?"

"So I'm boring you?"

"Noo. Ugh, I'm not explaining it well," Ty Lee replied, feeling exasperated with her own communication skills at the moment. Taking a moment to think, she let her mind try to focus on what she was trying to say, eyes widening as it came to her. "It's like when you see something you never expected to see it tends to stick with you for a long time and has a lot of impact, right?"

"I guess…?"

"Well, when I saw them at the library it was kind of like that. And it got me thinking about sex, like ALOT about sex, and that made me think of you and me having sex. Like ALOT of sex," Ty Lee explained further, her cheeks flushing pink as she felt the urge to jump her girlfriend begin to swell within her very being.

Mai said nothing for a minute, letting what her girlfriend had just said register in her mind. Looking into the stone grey eyes, she looked for any sign of misdirection or falsehood, only being greeted with the usual bubbly sparkle that seemed only possible for the rather unconventional young woman.

"God, you're way too smooth for your own good sometimes," Mai sighed out, letting her arms slip around the limber girl's waist, planting a soft kiss to her lips. Breaking the kiss she leaned in a bit deeper, letting her lips brush softly against Ty Lee's ear as she whispered to the busty brunette.

Ty Lee's face lit up a much darker shade, a burning crimson flaring on her cheeks. Blinking as though she could not believe what she had just happened, she more firmly pressed her legs together, chewing on her lower lip with anticipation. With a nod of her head, she grabbed Mai's hand and made to leave the apartment.

"Sorry guys we have to leave like right now," Ty Lee offered in apology to Katara, Suki and Sokka.

"What!? Did you forget why we came here in the first place?" Katara's voice nearly broke with exasperated indignation, causing the pair of fleeing lovers to pause for a moment.

"No, you mean why you came in the first place," Mai said in her usual indifferent tone, letting her eyes wander over to the apparently unaffected pair of siblings. "I was hoping to see Azula squirm a little bit, but obviously that's not happening," her words slipped out with a teasing sort of defeat, the smallest inkling of a smile cracking across her elegant features.

"So you're the one we have to thank for this little impromptu get together," Azula retorted in realization, her own lips pulling into a triumphant grin.

"Something like that. Me and you can talk about this some other time, one on one, because I'm not totally sure I'm okay with this situation, but that's for later."

"What's happening?" Suki asked, completely lost at the turn of events that had transpired. "I thought you were disgusted when you heard about the situation?"

"I don't know about you three," Mai returned, letting her eyes wander from Suki to Katara then finally Sokka, "but I always kind of knew there was something pretty weird about how they used to act growing up, so I'm probably just not as surprised as I should be." Her words caused the other three to slip into introspection for a minute, thinking back on the interactions they had witnessed between Zuko and Azula over the years.

"Now that she mentions it," Sokka mumbled, hesitantly letting his eyes wander over to the lovers on the sofa, Azula's body shifting ever so slightly as she playfully rode Zuko.

"I guess I just never wanted to think about it that way," Suki added, completing Sokka's thought as she shifted her eyes over to Katara, who seemed to have a similar thought.

"So there you have it," Mai concluded, locking eyes with Azula to be sure she knew they would indeed be having a conversation about it at a later date, but that she was off the hook with her for now.

"Then, we'll be going," Ty Lee chirped, throwing her arms around Mai's neck from behind, pressing herself against her lover fully from behind.

"I am dying to know what Mai whispered to Ty Lee to make them leave so suddenly," Sokka mused, his mind whirling trying to figure out just what to do in the current situation.

"This being our apartment, you two are more than welcome to stay," Azula supplied, her voice fluttering a bit as it left her lips.

Mai and Ty Lee looked back to Azula in shock, watching the predatory grin on their friend's face.

"In fact," she added, a smolder glowing in her eyes as she eyed the two girls up and down, "you're more than welcome to come join us over here." Azula's voice was the very definition of sultry as it filled the room, wafting casually across the suddenly somewhat cramped living room towards her two friends.

"Azula!" Zuko and Mai exclaimed in unison, taken aback by the suggestion.

"You mean it!?" Ty Lee exclaimed, her enthusiasm palpable as it sliced through the once tense atmosphere.

"Under the condition that all of dear ZuZu's cum is mine," Azula offered in return, casting her gaze down into her brother's eyes.

"That's a deal!"

"What's even happening right now?" Mai sighed, feeling torn at the prospect that had seemingly been drawn out without her even properly being consulted. She was still quite confused at the state of affairs, and was more than hesitant at how her girlfriend was seemingly so entranced by the two, but at the same time she was admittedly quite curious what such a scenario might be like.

"I don't know," Zuko mumbled, keeping his eyes locked on his devious sister as her lips pursed in an attempt to stifle a laugh. As he blinked in surprise and obvious confusion, Azula felt the control over her reaction at his response loosen.

"Oh Zuko, lighten up, it was a joke," Azula teased, letting the laugh slip at the flustered, confused look on her brother's face.

"Aww, that's mean," Ty Lee huffed.

"Ty Lee…" Mai grabbed the limber girl by the hand, dragging her out of the apartment in a hurry. "I'm going to make sure you never think of anyone but me in a sexy way ever again," she added, lips drawn in a subtle frown.

"Oooo, that sounds fun," Ty Lee returned, her womanhood throbbing with the idea of what Mai had in store for her.

"I'll talk to you later," Mai shot back to her friend, taking a brief pause once she had exited the building. "And she's right, that was kind of mean. Don't try to steal my girlfriend ever again."

"I wouldn't dream of it," Azula promised, her playfully devious expression undecipherable to all but those who knew her best.

With a flurry of motion, the two lovers left the apartment, the clicking of the door in the lock resounding agonizingly through the deathly silence of the living room.

"What just happened…" Zuko asked, mystified at the turn of events.

"Just count your blessings, dear brother," Azula replied, leaning down to place a tender kiss to his plaintive lips. "Now it's a much more manageable situation, wouldn't you say?"

Zuko stared into the sparkling gold of her eyes, losing himself in the warm depth of the glittering pools. With a heavy sigh, he felt his lips quirk into a smile, hands resting on his sister's inviting hips.

"One of these days I'll be as good at reading a situation as you are," he promised, a mirthful chuckle sounding in the air between them.

"There is no need for that, dear, since you have me for that. Don't you ever learn, dum dum?" her voice was pure with warmth as she spoke, a subtle purr to the syllables as they dripped smoothly from her lips.

Katara, Suki and Sokka all stood there idly, completely lost in the events that had just transpired.

"Dude, did we just get played by Azula?" Sokka asked, blinking dumbly as he looked to his girlfriend for some kind of guidance.

"I think so," Suki replied, casting a mystified gaze at the ebony haired young woman across the living room. "I really can't stand her," she added honestly, lips pursed in an intense frown as her eyes narrowed in defiant annoyance at Zuko's sister.

"So, are we still going to do this whole interrogation thing?" Azula questioned, maintaining her perch atop Zuko's lap as she hid her bare body from the assembled group.

"We most certainly are!" Katara spoke up, her voice an out of control mess of sound.

"Fine, I suppose we should get dressed then," Azula drawled, making sure the implication of her statement was clear. She smirked at the soft flush that passed across the collected faces as she began to stand, her naked form coming into clear view.

"Yeah, you should," Katara grumbled, turning her eyes away from the naked young woman.

"No shame," Suki nearly spat out, likewise shifting her gaze towards anything else she could think of to look at in the apartment.

"You know," Sokka spoke, his eyes locking on the well developed form of his friend's sister, "she's got a really nice body." His natural careless attitude perked up in full force, earning a heavy punch to the arm from his girlfriend.

"You jerk!" she shouted, anger swelling in her face.

"Hey, I'm just being honest. Not as nice as yours for sure, but it's pretty nice," he spoke, only digging himself into a deeper hole even as he tried to placate his justifiably angry girlfriend.

"Sokka, I'm going to gouge out your eyes if you keep ogling my sister," Zuko's angered voice sounded across the room, his fingers deftly fastening the button of his pants before casting his gaze towards his friend.

"Oh Zuzu, my hero," Azula swooned sarcastically, throwing her arms around his neck from behind as she pressed herself fully against him. "But if he wants to look isn't it fine? It shows that he has good taste at the very least," she said seductively, nipping at Zuko's ear playfully, delighting in the subtle shivers that coursed through his body.

"I just don't like it. It's not like I go around checking out his girlfriend," Zuko replied, turning his head to gaze at his sister's face. The heated fury abated at the calming look from his sister, playful warmth evident in her well carved features.

"I should hope not. Else I would have to blind my own dear brother, and that would make me quite upset," she teased in response, ensuring that she locked eyes with the auburn haired young woman as she spoke.

The feeling of pure irritation at her boyfriend gave way to a gnawing self doubt at the clear implication of Azula's words. Clearly she was making it quite clear that Suki was not worth Zuko's energy to check out.

"Are you trying to say I'm not as hot as you are!?" she challenged, feeling herself being caught up in Azula's flow, but unable to hold herself back.

"Most certainly not. What I am saying is that my dear brother already has me, so no other girls are worth consideration," she countered in her usual arrogant, self assured way. Even if it was an act, there was no way to know for sure.

Suki's entire body trembled with anger, her annoyance with Azula's teasing bursting into a veritable volcano of unresolved tension. A huge part of her wanted to simply rush across the living room and simply throw fists at the bratty, arrogant young woman.

"Sukes, calm down," Sokka's voice pierced the haze of fury, his blue eyes sparkling as he held his girlfriend's hand. "You're the most beautiful woman in the world, I don't care what anyone else says," he supplied honestly, pouring forth all the love he had for her into his voice.

"Sokka…" she whimpered softly, her chest squeezing tightly at her own stupidity for falling into Azula's sneaky speech. "I'm sorry, she just gets to me, you know?" she continued, allowing her body to be pulled into his strong, reassuring embrace. Slender arms wrapped around his waist, her face burying itself into his chest as she drank in the feel and scent of his body.

"I know," Sokka replied, his fingers slipping through the silky locks of hair atop her head as attempted to reassure her. "She has that effect on people," he continued, the two sharing a chuckle with the truth of the statement.

"At least I'm not the only one," Suki murmured, her eyes closing as she sank fully into his embrace.

"Props to Zuko for dealing with that kind of crazy energy all the time," he made sure his voice carried to his friend, genuine respect mingling with the confusion and bewilderment of the situation.

"Thanks, I guess?" Zuko replied with some confusion, unable to tell if he had just been given a compliment or not.

"Look," Sokka said directly, locking eyes with Zuko as he spoke. "I don't really get what's going on with you two. I think it's weird and creepy and kind of gross," as the words spilled from his mouth, Zuko and Azula could feel themselves getting defensive, unsure exactly where he was taking his little makeshift speech, "but, I know you guys had kind of a weird upbringing, so like Mai said, it's probably not really that surprising."

"Does this count as your blessing?" Suki asked hesitantly, utterly lost for more impactful wording.

"I wouldn't say my blessing, exactly, but I mean, just look at them," he offered, causing Suki to shift her attention to the pair of siblings across the room.

She had to admit, Azula looked quite calm, almost happy even as she embraced Zuko from behind. And Zuko had been noticeably more collected and even over the preceding couple of years… ever since Azula had come to live with him.

"They do look pretty happy," she replied after a moment, feeling her natural indignation over the situation begin to crumble and fade away.

"So like, maybe we don't really need to get it. We love Zuko, and we can't stand Azula, so nothing really changes just because they're together," Sokka had to fight a shudder at the thought of the two of them together, even as his stomach felt a distinctive twinge as he pictured such a scene.

"Why do you have to be right about the dumbest things," Suki sighed in exasperation, her eyes blinking softly as she gazed up at him.

"Hey, I'm right about a lot of stuff," Sokka responded defensively, taking umbrage with being essentially told he was seldom right.

"Sure you are," she said playfully, a smile pulling across her face at the annoyed fluster on his face. "But regardless, I love you, you big dope," she said sweetly, lifting up on her tip toes to give him a gentle, warm kiss.

"You guys can't be serious!?" Katara broke up the warm atmosphere, heart beating quickly in her chest at how seemingly easily the wind had been drawn from the sails of their little group. "Did you forget that they're brother and sister!?"

"Well," Azula whispered in Zuko's ear, pressing her shirt clothed chest as firmly against his broad back as she could manage, "I think there's just one left to worry about," she added, hands caressing his chest teasingly, signifying that she was not done with him just yet.

"Oh sure, leave the most difficult one for me to deal with," he mumbled, casting his gaze towards the furious young woman across the room.

"I can't do everything for you, after all," she purred in his ear, letting her tongue flick playfully against the sensitive flesh. As the shiver slithered down his spine, Zuko thought about how he could handle this situation in as quick a manner as possible. A flicker of an idea spurred into his mind, sighing internally as he tried to get into the right mindset for it.

"Even if everyone else is fine with this little… arrangement," Katara sneered, casting sidelong looks back to her brother and his girlfriend, "what's wrong is wrong," she continued, steeling her gaze as she looked at the unapologetic siblings.

"And why is it wrong, exactly?" Zuko challenged, recalling back to all the times he had thought about it over their time together. He knew logically where she was coming from, that it was inherently strange to be attracted to one's own family, but any time he had that thought, he thought to just how right it felt to be with Azula. He couldn't bring himself to think of it as wrong, even if he knew he probably should.

"Do I need to spell it out for you!?" Katara felt incredulous that she had to explain something as basic as this to him.

"Maybe you do," he shot back immediately, feeling his instinctual defiance take over, "I love her, Katara." Azula felt herself immediately swoon at such a direct declaration of how he felt, her heart feeling as though it would burst with affection.

"That's normal, you're supposed to love your family," Katara replied matter of factly, "but not like that," she continued, waving her hands towards the two of them to signify what she was talking about.

"So what if it's not completely conventional?"

"Not conventional is oversimplifying it way too much," she said in a huff, taking a few steps towards the young man in front of her. "You know what I mean. It's sick," Katara let her disgust coat each word that dripped from her mouth.

"So what do you think is going to happen?" Zuko questioned, channeling his teenage self as he bunkered into his position. "That you're going to talk shit about the situation, and I'll just be like 'Oh geez, I never realized that, you're totally right' and just end things?" His eyes narrowed dangerously, forcing her to instinctively take a step back.

"Yes?" she replied somewhat hesitantly, taken aback by just how confrontational he was being about the entire affair.

"That's not going to happen, Katara,"he said sternly. "To be perfectly honest, what I do with my love life is none of your business." He hated how easy it was to drop back into the mean, confrontational kind of persona he had when he was younger, almost as much as he hated how insanely warm and comforting it felt.

"Well excuse me for not wanting to see you ruin your life. You know there's no future in a relationship like that," she responded, bringing forth her own inherently defiant nature.

"No future?" his mask slipped ever so slightly, wondering what she was possibly getting at.

"You mean you didn't realize it already?" Katara could tell she had the advantage now, a subtle smirk gracing her features. "It's not like you two can get married or anything like that, since you're, you know, siblings," she added, watching as his entire body seemed to lose steam at her argument.

"So what…" he mumbled, mind racing as the realization fully dawned on him. It hadn't really been something he'd thought about, all of his focus on making Azula as happy as possible. "Even if we can't get married, I think I still make her plenty happy, and honestly, that's enough for me."

Azula felt like she was about to turn into a puddle of goo at the annoyingly sweet way he spoke, promises of ravishing him later running through her mind.

"And I'm assuming you haven't exactly been safe either. Don't you worry about what your kids will be like?" Katara pressed an accusatory finger into the center of his chest, glaring daggers as she spoke.

"Azula would be a great mom," Zuko responded with no hesitation.

"Yeah, she's soo stable," vindictiveness and bitterness slipped into her tone of voice as she spoke, recalling all the odd arguments the two young women had had over the years.

"Katara, you know I respect you and all that, and I don't want to have a fight but you should apologize. Now." Taking insults himself was one thing, he was used to it. But he wouldn't have anyone question his sister or doubt the progress she had made.

"And if I don't? You know it's true. Honestly, I'm not sure how fit a parent you'd make, either," she was speaking purely out of spite now, not able to stop the words as they flowed effortlessly towards the young man.

Zuko could feel his body begin to shake with anger, the practiced demeanor giving way to genuine rage. Sokka and Suki felt a distinct discomfort pass through the apartment.

"Katara, I think that's a little harsh," Sokka spoke up, sensing that things were getting far too heated.

"It's just the truth. Anyone who would have sex with their own sibling definitely has some kind of issue, and definitely shouldn't be having kids," she spat, not even turning to look at her brother.

"My my, such hostility," Azula spoke up as she moved to take position next to Zuko, arms crossed casually as she earned the glare from the blue eyed young woman. "I had no idea until this very moment," she added, an inherently vague hint to her voice drawing everyone's attention.

"That Zuko would make a terrible father?" Katara sneered, a malicious smirk on her face as she spoke.

"Oh, no not that, my dear ZuZu would most definitely make an excellent father," Azula waved the notion of Zuko being a bad father completely off, despite the mere questioning of his character making her want to do some completely vile things to the tan skinned woman.

"Then what did you realize?"

"That you're in love with Zuko," Azula let the words slip with a slow, methodical calm, making sure everyone understood exactly what was being said.

"What!?" Katara's face lit up a dark shade of red at the suggestion, the wind completely leaving her sails. "How could you even think that. I don't, there's no way, I have a boyfriend already," Katara was floundering, thrown completely off guard.

"Yes, yes, boyfriend being quite an accurate statement," Azula pushed her advantage, lips curling into a predatory grin as she stared right into the sapphire blue pools. "But the fact remains that you're jealous that you're not the one that he chose to take to his bed and shower with affection."

Katara lost her cool entirely, mind swirling as she sought to regain her footing, to deny what had been tossed casually into the open. She could feel four sets of eyes locked squarely on her, disbelief etched on all their faces save for one.

"That's not what this is about at all," she replied weakly, shifting her eyes from the eldest member of their little group, staring down at the smooth wood of the floor. "It's about the fact that this whole thing is wrong. It's not a relationship, it's incest for God's sake," she regained some of her focus, lifting her gaze to the unflustered young woman to Zuko's right.

"And?"

"And…? What do you mean 'and?' that's wrong," Azula's defiant refusal to acknowledge the wrongness of it flustered Katara once more, Sokka and Suki watching dumbfoundedly at the ease with which Azula had managed to work the scenario in her favor.

"If you say so," Azula offered simply, running the points of her fingernails casually through the messy locks of silky ebony framing her face. "But the only people who say foolish things like that are ones with ugly siblings," she threw out off handedly, watching with devilish delight as Katara's mouth hung limply open.

"What? No, that has nothing to do with it, it's wrong on its own," Katara muttered, earning a roll of the eyes from Azula.

"Whatever you say, dear. But I think my brother has made his position quite clear, and I will just add that he has my full support, so I believe we are done here," Azula said carefully, leaving her intention to one day bear his children clear as day.

Reaching out to her right, she clasped her brother's hand, tugging gently to indicate he should follow her. He followed numbly behind her as she entered her bedroom, his mind struggling to process what had just happened.

As the door to Azula's bedroom closed, the beginnings of an undoubtedly silly argument between Katara and Sokka resounded through the small domicile, something that normally Azula would take great delight in witnessing.

"Azula, I, did you mean that?" Zuko asked, taking a seat on the edge of her bed.

"What, that people who think incest is wrong have ugly siblings?" she asked playfully, knowing full well that was not what he was referring to. "I do understand the notion that it is not something that should be indulged in as a matter of course, but like you so eloquently put it, if two people care for one another, then nothing else truly matters."

"That's not what I meant and you know it," he retorted, tugging her hand to pull her down towards him. He smiled as he felt the comforting pressure of her body against his as she straddled him again, pajama covered legs bracketing his thighs as she settled into position.

"Of course I meant what I said, dum dum," she spoke, dropping the teasing act as she answered his query. "You will make a terrific father one day, so…" she let herself trail off as she began to undo the buttons of his shirt. "Let's get started on that right now." The urge she had been feeling since he had declared his feelings for her took hold as she slipped his shirt off, revealing his strong body to her lustful gaze.

As Katara and Sokka argued stupidly over whether or not she found him attractive, which he didn't truly care about if he was being honest, Suki sighed in annoyance.

The bickering came to a halt as they heard the distinctive sounds of lovemaking echo down the hall, the three looking squarely at each other.

"We should probably, uh, go," Sokka mumbled, his mind unfortunately filling in the scene for him, eliciting a creeped out shudder.

"Definitely," Suki replied, hurriedly clasping Sokka's hand and making to leave the apartment. "I don't know if I can ever be okay with this," she added, the reference clear.

"Me either, but I think we can try to be supportive?" he was distinctly hesitant at the notion, but Zuko had always been there for him, so he had to at the very least try.

"Disgusting," Katara spoke bitterly as she followed the two, casting a sad look down the hall before slamming the front door shut on the way out.
