AN: This is a dreaded Modern AU, I forewarn you. But the image of Azula and Ty Lee secretly hooking up in school uniforms has been stuck in my brain for like a week now. However, it takes place in the Avatar Universe, with bending, the royals, and other aspects of the series, but the setting is a 2015-esque world.
It was a oneshot, and is now continuing.
This started T rated, but now is M for moderate sexual content and drug abuse.
I also forewarn you that this a combo of 80's Movie Campiness, and the 90210 and Gossip Girl genre of awful and amoral rich teens (it's centered around Azula, I mean...), and is a bit satirical of itself. However, I do have a serious plot, and character/relationship development.

Liar in a Little Plaid Skirt

Book One: Junior Year

Part One: Fall

Chapter One

Two girls step into a nearly empty penthouse, large, exquisitely furnished and illuminated by the lights of the city. It is already dark out, as it is mid-autumn already, and Azula is only just making it home from school, dragging her girlfriend along with her, with the promises that they would be alone, and be able to indulge in something quite interesting. Ty Lee half imagined she would be taken to the palace, although she does recall it being exclusively for political work and the royals not living in it.

Ty Lee looks around. She has never been to Azula's house before, although she herself lives in an expensive house in the Upper West Side of Caldera Metropolis City and she has been inside of many, given her elite social group of friends. But this is a new level of decadence. Hues of red, gold and black are all perfectly matched in a beautiful apartment centralized around an electric fireplace.

On the mantlepiece are only pictures of Azula. Not her brother, nor her deceased mother, or even her father. Just Azula. Ty Lee's pictures have to fight for space, even if people could recognize which girl was which.

Azula grabs Ty Lee's slender, smooth wrist and tugs her down the hall towards her bedroom.

"So, he's definitely not home?" Ty Lee asks hesitantly as she tosses her bright pink, ruffled backpack with the cartoon turtleducks on it into the corner of Azula's bedroom.

"I would not lie about that," Azula purrs in response, shutting the door with her heel and sitting down on the foot of her bed. "I would be in just as much trouble as you are."

Ty Lee grimaces. "I find that kind of hard to believe."

"Relax," Azula says sweetly, seizing Ty Lee's blood red school tie and pulling her into a kiss that makes their teeth smash together. "I am completely in control."

"Mmm?" Ty Lee quite likes the sound of that.

Their hips are linked, heat surging between both of them, Azula's hand sliding up along the smooth thigh of her counterpart, pushing the black and red plaid skirt up, up, up and...

Crash, click... and Ty Lee pulls apart from Azula, and a riiiiip is contributed to the sounds that interrupted their heated make-out session. And there goes Ty Lee's only not-stained white blouse. Azula tries not to look stunned as she pulls Ty Lee back to her, quite enjoying the new, exposed view.

"Who's there?" Ty Lee asks, her heart pounding and Azula sighs.

"We're probably being robbed. There are soldiers and secret service outside; it's probably one of them," Azula replies softly as she kisses Ty Lee's neck. It gently escalates to soft moaning and the utter bliss of being alone together.

Ozai has returned early from work, meetings with the Northern Water Tribe and other important affairs, and although he is known for remaining in his office at the palace until three in the morning during this time of year. Azula is home; no one else is. It is then that he hears something relatively disturbing, that would be any father's absolute worst fear.

Moaning.

Azula and Ty Lee are leaning on the side of Azula's bed at this point, having slid down from their perch on the mattress. Things are progressing at a rate that is both thrilling and terrifying to both of them when there is a knock on the door.

"Azula, open your door," comes the last voice Ty Lee ever wanted to hear.

"I'm not wearing any clothes!" Azula shrieks as she pushes Ty Lee onto the floor and stands up.

Ozai hesitates, sincerely hoping there is not some adolescent boy in there also not wearing any clothes. Ty Lee is on the verge of a panic attack as Azula pulls on a bathrobe, ties it tightly and opens the door.

"This is Ty Lee," Azula says, gesturing to the girl with Azula's blankets draped over her body. "She's my friend from school and we're having a sleepover and watching movies."

This is definitely not how Ty Lee imagined meeting her girlfriend's father would go. Here he is, the most powerful man in all Four Nations, and Ty Lee is half naked on Azula's floor, desperately trying to pretend she was not about to lose her virginity to his daughter.

When he sees it is just some girl from Azula's school, the Fire Lord is relieved, he supposes. He looks between them, still picking up on the unsettlingly sexual nature of their flushed cheeks. But Azula has only one friend; the grim, sullen girl he so dislikes seeing her with. He should, he supposes, encourage a friendship with someone who looks a tad more... wholesome (or at least wears make-up).

"She can join us for dinner, if she would like," Ozai says before closing the door and removing himself from the situation. Princess Azula dares to breathe a small sigh of relief.

Ty Lee looks at Azula, her coral pink lips opening and closing with no sound coming out.

"Relax," Azula says, smirking at Ty Lee. "He never has to know."

And then Ty Lee rubs her lips together and dares to say, "What if I want him to know?"

Azula scoffs and crosses her arms. "Why would you want that? I doubt my father will allow me to date until he's dead. And I... I... li... I want you. I want you and I hate admitting I want things, alright? And more than that I hate not getting what I want."

Ty Lee feels her cheeks flush not with the rush of near sex, but with the sensation of Azula actually expressing her desires. Her romantic desires.

"Well," Ty Lee says, standing up, unabashed of her body half clad in a school uniform and half in a frilly pink bra, "I'm going to pretend that it's my first dinner meeting your father as your girlfriend. I think I can be really impressive."

Azula slowly shakes her head. "I think it'll be best if you say as little as possible. You aren't really my father's type, unless you're talking about the nineteen year old one night stands..."

"Relax," Ty Lee says with a grin and Azula struggles to swallow. "I am the epitome of perfect girlfriend. Or, well, friend from school. Soon enough, he'll be begging me to date you."

Azula cocks an eyebrow.

She thoroughly and utterly doubts that her girlfriend whom is only passing school because of her extreme adeptness at cheerleading and family fortune that purchased the new library will impress Ozai. However, Azula does appreciate the gesture, and the danger... oh, the danger is a bit thrilling. Azula has only ever played by the rules and been the perfect daughter, perfect student, perfect firebender, perfect everything. The idea of a secret, hot, fiery affair is... exalting.

"Either way, I will fuck you inappropriately hard afterwards and we can pretend we're discussing boys and make-up," Azula replies, her evil smirk widening.

Ty Lee cannot help but smirk in response.
