Azula had demanded him to take her shopping before her birthday. The two of them, and their family, weren't going to celebrate it until the actual day, and Zuko doubted they'd have much, if any, alone time when it happened, so he didn't object to it, the thought of an entire day with her being more than worth both of them spending a ridiculous amount of money, especially now that their family had finally accepted the fact that there was no point in not allowing her to leave the house when she'd be able do whatever she wanted very soon anyways.

After many hours buying anything they wanted, his sister decided to get some new lingerie. Since pretty much everything was really expensive, there weren't many people at the store. Azula picked up everything she wanted to try on and then went to the changing booth. He felt a bit like a body guard, keeping an eye on all the man around to make sure they wouldn't even consider trying to catch a glimpse of her.

When she opened the door again, he saw her wearing a simple two-piece white set, with a semi-transparent robe of the same color that went down to her knees. She had even freed her hair from the top-knot she liked so much, the dark locks framing her pretty face, contrasting with her pale skin. It gave her an innocent air that was so unlike her, and Zuko loved it.

"Come on, dum-dum, at least give me a kiss if you want to convince me it really does look good on me" she asked which a cheeky smile, and he happily obliged.

"You look like an angel"

She gently pushed out of the booth and locked it again, in a failed attempt to hide the lovely shade of pink on her face.

For the next one she got a bit more bold, definitively trying to get back at him for making her blush. The dark red of the short nightdress suited her well, and the fabric covered just enough of her breasts and thighs to make him want to rip it off her body. She then let it slide down her body, revealing a tight, black and red one-piece that framed all of her curves just right. She smirked and winked at him as she saw his jaw hit the floor.

"See something you like, honey? Oh, let me show you how the back of it looks!" she turned around and he clenched his hands into fists, knuckles turning white as he forced himself not to give her a slap on the ass.

"Don't tease me" he warned, still feeling the heat on his cheeks.

"What's the fun in that?" she replied before changing into something new.

This time, she was wearing dark blue bra and panties, with a black garter belt and stokings. She even made a point of putting her high heels back on. He instantly began to picture her with her hands and feet bound, with a ball-gag on her mouth, then tied to his new bed, and even with a whip in her hand, ready to turn the tables on him.

She was driving him insane, and the fact that he couldn't just have her then and there only made him want her more. Each time she locked the door so she could change into a new set brought him both relief and agony.

Azula continued with her act, trying out everything she felt would rile him up until eventually she decided to just wear a see-through black robe... with nothing underneath.

Zuko just couldn't control himself anymore. He took advantage of the fact that there was finally no one else was around at that moment and snuck into the booth, quickly locking the door, seeing her wearing a red two-piece lingerie - and reaplying her favorite red lipstick to match it. He smirked, wasting no time and hugging his sister from behind, kissing her neck.

"What do you think you're doing?" she reprimanded him as quietly as possible, looking a bit scared, but still clearly just as excited as he was.

"Teaching you to stop being a tease"

"Good luck with that" her playful tone and the dangerous, lustful look in her eyes only encouraged him to go on "You're going to get us in trouble"

"Come on, you said you'd do anything I wanted after we told everyone the truth" he snuck his hand into her panties, smirking as Azula gasped and trembled at his touch "And besides, I still owe you a reward for being such a good girl at that family dinner" he rubbed quick circles on her clit, making her moan.

"We gotta be fast" his sister warned as she allowed him to take off her panties and pressed her hands to the wall in front of herself for support, bending over slightly, waiting for him to do whatever he pleased. Zuko couldn't think of a better sight.

He pulled his pants down a bit, pushing his cock inside her, the two of them fighting back moans of pleasure as he gave it to her slow, but hard. Azula told him to speed up, but he paid her no mind, just enjoying the sounds of her soft gasps of pleasure and the feeling of her squeezing him, moving back against him, tensing up whenever she heard anyone walking by. One of his hands was holding onto her waist firmly, and the other was freely roaming her body, feeling her up, groping, teasing, pleasuring and burning her, all while he pressed his lips to her shoulder and hid his face on the curve of her neck whenever he couldn't help but moan.

It didn't take long for him to come, and when he pulled out his sister assumed he was done, but he just couldn't stop touching her, kissing her, keeping her as close to himself as possible, not giving a damn if someone could hear them or walk in on them.

"God, you're such a pervert" she said, despite the fact that she had arms around him and was obviously delighted at the attention.

"You know I can't resist you, Zula. And besides, we both know you'd make me pay for it if I didn't satisfy you"

She smirked, running her fingers through his hair "Good boy"

As soon as he got hard again, Zuko made Azula wrap her legs around him, pressed her up against the wall, and kissed her as he started fucking her once more, making sure she wouldn't be too loud.

It wasn't enough. Azula's moans became louder and louder, and he couldn't help but get just as carried away - and perhaps he liked the thought that people knew they doing. They heard knocks at the door and very horrified screams, but didn't care in the slightest, taking their time, fully lost in the moment, wrapped up on each other, not stopping until they were satisfied.

They were kicked out the second they paid for all clothes Azula had so much as looked at. He found it amusing that everyone had been too scandalized to properly interrupt them to get rid of them sooner.

He had barely started driving away when he felt his sister's hand on his thigh, slowly moving towards his crotch.

"And I'm the one who's a pervert, huh?" he teased as he frantically looked for a spot where he could park his car.

"Shut up" as soon as he slowed down, she unbuttoned his jeans - with her mouth.

"God, I love you" his right hand was already grabbing her hair, making sure it wouldn't fall on her face, giving her a little attention, and showing her he was still in charge all at the same time.

She chuckled "What can I say? You deserve a reward after fucking me so well and spending all your money on me"

"That's my good girl"

Azula looked up at him, allowing him to see her loving smile, then got back to 'work'.

He really was a lucky man.
