Boredom

Title: Boredom
Pairing: Firecest (Azula/Zuko)

"A-Azula," the once-exiled prince managed, "...If you don't stop now, I'll--" Before he could finish, he groaned as that clawed hand tightened viciously around his throbbing shaft while a burst of azure fire flew past, dangerously close to his face.

"...I don't think you're in any position to be making threats, Zuzu."

The chiding tone in his sister's voice only made Zuko's indignance burn deeper within him, but despite his best efforts to move Azula had him firmly pinned, and he didn't dare try to attack her-- he'd gained great favor with his father recently, but that didn't mean the Fire Lord wouldn't choose the... more loyal of his two children again if the time came.

For her part, Azula was nothing if not amused. She'd held the fancy in her mind-- sometimes, and only for a moment-- whenever Ty Lee and Mai weren't around to satisfy her, which thankfully wasn't often. But they were gone on a personal errand for her now, keeping watch over Ba Sing Se in her absence, and that little quiet nagging in the back of her mind had finally gotten the better of her, taking advantage of her libido and boredom.

"And for complaining so much, Big Brother," Azula added as she slid down his body, her sharp fingernails raking his sac harshly, "...You definitely seem to be enjoying it."

"Y...You're wr--!" Zuko's protest died in his throat as his sister's hand gave his cock another hard twist, triggering a small orgasm; he twitched as he came, hips thrusting fruitlessly into the air. Azula nearly cackled as his movements reminded her of a dying animal. As Zuko struggled to catch his breath (the only pleasure Azula intended on allowing him), the Princess dabbed a finger in the little glob of cum that was now scattered around her brother's pelvis, then experimentally licked it. Ty Lee tasted much better, she quickly assessed.

Azula sneered as she stared at Zuko, whimpering like a child; she had no intention of letting him get his second wind entirely, of letting him think for a minute that this was somehow a mutual source of pleasure. There was only her satisfaction that mattered, and if Zuko had to be crushed even lower than he already had been for her enjoyment, then so be it. With that in mind, she quickly slid a pair of fingers along the split of his firm ass, then plunged her fingers into the pulsing ring.

Zuko's eyes flew open at the unexpected intrusion, his breath coming out in deep hiccups as Azula finger-fucked him.

"Wh..What the fuck are y--"

"Don't you DARE act so coy," Azula cut him off, smiling wickedly. "We both know that you love this. Who knows how many times this has been stretched?" As if to illustrate her point, the Fire Princess added a third finger, moving even faster than before. And while Zuko grit his teeth and didn't let a single moan escape his lips, the speed with which his limp dick went erect again betrayed him.

Eyes glinting haughtily, Azula stood up, then let her open silk robe slide off her like quicksilver. It didn't matter if Zuko was aroused further by the sight of her or not-- as far as she was concerned, he should be so lucky to be, well, raped by his superior sibling. She moved slowly, confidently as she straddled him, licking her lips as she reached beneath her to pull his pulsing meat into position, not betraying her slight uncertainty as she took his full length in a single thrust.

Zuko groaned involuntarily at suddenly finding himself sheathed in his sister's tight heat (Azula failed to stifle the tiniest of coos as his cock filled her-- enough to relieve her immediate restlessness but not enough to make her swear off her two lovers), his dull horror fading slightly as sensation took over. Azula quickly recovered though, fighting the urge to laugh at how easily her foolish brother had succumbed. Instead, she dug her claws into Zuko's chest and began to move her hips up and down, following the curve of his shaft.

"Fuck me, Zuzu," Azula taunted, her eyes hardened in cruel dominance. "...Prove that you aren't completely useless for once." With that she continued riding her brother, wriggling her hips on occasion to make his cock hit the spots Mai seemed to be able to reach so easily.

And at the thought of the stoic girl, Azula's lips curled darkly again.

"I have... to say... Mai was right. You aren't... any good at this..."

"Don't talk about her," Zuko growled, suddenly changing from detached participation to indignant again. But it was too late; Azula had hit a nerve, and now all she had to do was keep prodding. The Princess kept talking, her steady pace unchanged.

"Why Zuzu... You always... say that I... lie, but when...I'm honest...you get upset?"

"Shut up, Azula--" He gasped as she pressed her full body against his, her lips close to his unburned ear.

"You should hear her beg," Azula whispered, her voice smooth as poisoned honey. "'...Ohhh, Azula...faster...faster... I'm going craz--aahhh!'"

At that moment something in Zuko snapped; he grabbed Azula's hips and started screwing her with such ferocity that she was actually moaning, getting wetter with every violent thrust. Soon enough she was matching his thrusts, delighting in the fury she'd forced out of her brother.

"Yes-good-ah-Zu-hah-zu-fuck-ah-me-like-hah-th--"

She hit her orgasm a bit quicker than she'd expected, coming with a ferocious, guttural moan as she felt Zuko's seed fill her, her experienced pussy tightening to squeeze every drop of Zuko's shame out. It only took a few minutes for Azula to stand up, still panting a bit, grinning as Zuko's cock slid out of her, the sight of their combined juices dripping out of her almost making Azula want to fuck her pathetic brother again. Almost.

"It's so easy to get you riled up, isn't it, Zuzu?" Azula asked derisively as she grabbed her robe, leaving the Prince spent and dead-eyed on the ground.
