Still on the brink of a release, Katara shuffled about, oddly perturbed and thinking about relieving her pent-up tension herself. All she'd need is a few well-placed strokes and maybe a flick or two, and then she'd be good. But she promised Zuko that he could have that honor, so she bit her lip and ambled down the hall, leg twitching and pants growing uncomfortably wet as cum dripped steadily into her panties.

"Ugh," she snarled, growing annoyed with the constant dribbles.

She could shower and rid herself of the mess, but then she might get a little excited and accidently agitate the little love-nub between her legs. And since she didn't want that, she plodded directly to Zuko's apartments, willing to sit in her lover's jizz until he came to collect her and finish her off.

After finding a discarded scroll about water treatment and sewage removal, Katara started reading, feigning interest in the bland and sometimes disgusting topic. She rolled her eyes over the content, dropped the book back on the table where she found it, and padded to Zuko's bed. She stripped, fighting the increasing urge to circle her clit, and crawled into bed.

Her routine demanded that now was naptime, and she had no qualms with that. It would allow her to ignore her aching midsection and enter a dream; though, she imagined that said dream would be sexually-charged. But it wasn't like she really cared; her fantasies were always filled with images of a naked and fully-erect Zuko. He was always nipping carefully all over her body, ravaging her with slick kisses and hot fingers.

Her hands shifted between her legs and then stopped just at the beginning of her slick slit.

"Fuck, Zuko," she growled, royally pissed off that he hadn't finished her off in the library.

She smacked the large swath of soft skin above her entrance and groaned, knowing that she shouldn't have done that. The vibrations from her assault intrigued her bud and she clasped her hands above her head to prevent herself from doing more.

She'd need some sort of binding to keep her hands away from her aching clit. Blue eyes shifted around the room, thinking of different items should could use.

Handcuffs!

Zuko had deposited the blue-furred restraints in his nightstand for future use after their last adventure. So she rolled across the king-sized bed and rummaged through his drawers, tossing mountains of unused condoms behind her back as she searched. She found the first pair coiled around the large, tan dildo, and she found the second a little further back in the drawer. Satisfied, she shimmied to the middle of the bed, swatting foiled packages out of her way.

Finally where she wanted to be, she lurched forward and snapped one cuff around the bedpost. She linked the other cuff to the opposite post and clicked the restraints around her wrists. The final cuff was difficult to lock, but she managed it after a few seconds of struggling.

Tied up, she stewed, wondering if what she just did was a good idea. She shook her head at her thoughts, closed her eyes, and tried to ignore the world around her, desperate for sleep.

When Zuko was finished with his meeting, he walked to his apartments, scroll to his nose, going over the reports that had been discussed for the umpteenth time. He pushed the door to his room wide open, still reading, before his golden gaze flicked upward and he abruptly stopped.

Propped against a mountain of pillows, chained and naked…was Katara.

He dropped the scroll he was reading and sprinted to his bed. Before he jumped into the sheets, he realized that she was sleeping, her head braced snuggly against the soft, downy pillows. His lips were dry and he smacked them together, delighted with the endless possibilities of what he could do with the slumbering and bound bender.

He stilled, looking over her prone form and he licked his dry lips. But his tongue was like sandpaper in his mouth and he needed something deliciously wetter to quench his thirst.

Darkly brooding, he slunk to the end of the bed and pulled back the covers. He crawled inside and nudged her legs apart, propping them slightly over his shoulders so they'd be out of the way.

Under the sheets, the smell of sex was strong and Zuko's member twitched against the mattress as he crawled closer and closer to the sleeping girl's slick entrance. In the dark, he nosed forward, smoothing his tongue over her nether lips so he could taste her delicate insides. His tongue darted around her clit and down into her entrance, licking up the remaining taste of his ejaculation and her eager, unfulfilled desire.

She stirred and he could barely hear the cuffs clack against the bedposts.

Zuko wrapped his arms around her thighs and pressed his thumbs into her muscles, heating his hands as he massaged her flesh. He continued to flick his tongue around her clit, circling the little nub before zig-zagging the blunt point overtop it.

"Ooooh," Katara gasped. Her eyes fluttered and her hands tugged against the handcuffs. Still thinking that she was dreaming, she closed her eyes completely, envisioning her lover licking her up, his chin slick with her body's desire.

A heated breath blew through her aching slit and blue eyes snapped open. This wasn't a dream. There was a man between her legs, expertly eating her out.

A warm tongue glossed over her entrance before scalding fingers pried open her nether lips, allowing him greater access. The wet, wiggly protrusion dipped into the glistening walls of her pussy, darting all around and lathering every available inch with a thick coating of saliva.

Katara moaned, feeling the tongue search deep into her folds before popping out. It circled her clit, running clockwise until it passed over the nub. Then, it spun counterclockwise for a few turns.

"Fuuuuck, Zuko," she breathed, wishing she hadn't tied herself up. All she wanted to do was shove her fingers deep into his hair and tug on the black locks as he licked up and down her entrance.

Realizing that she was finally awake, Zuko smirked into her snatch and wriggled one hand over her tummy, fingers gently caressing the skin as it continued its northward journey. When he reached his desired destination, he cupped the base of Katara's left breast and rolled his thumb over her perky nipple. He could feel every little bump on her tit, and he released her so he could wrap both arms around her thighs.

He returned all of his oral attention to her clit and simultaneously nuzzled her vaginal opening with a gentle finger. He inserted the digit and started pressing softly against her upper walls, testing the area affectionately.

When Katara groaned and bucked her hips a little bit, Zuko knew he had the right spot. He inched his fingers along the small area, slowly dabbing it and causing the waterbender to thrive and kick her legs out involuntarily.

While fingering her, he continued swirling his tongue over her clit, heating up the area with well-timed breaths.

Katara was gushing and writhing over his touches. She grunted and clawed at the cuffs, cursing her stupid decision. Zuko's touches were quickly claiming her, rapidly filling her with a desperate desire that would soon come to a messy close.

She had heard of other women doing it, but had never experienced the sensation herself. And with Zuko applying gentle pressure to her g-spot, wriggling his tongue over her clit, and heating her snatch with warm huffs, the compression was building. And soon—so very soon—she was going to pop and break free.

"No, nonononono," she whined, back arching as he flicked her nub with the tip of his tongue. His fingernail dug playfully against her inner wall, sending a wild spurt of need through her. "Aahhhhhh," she groaned, bucking her hips once more.

Zuko breathed into her once more, and it felt like he was playing her as one would play a musical instrument. Her clit was his button, her g-spot, his slide. And he was the master, forcing her to emit whimpers and unholy sounds she didn't know she could utter.

"Zu—Zu—"

She couldn't finish. Her knees tried to clamp together, but Zuko's body prevented her from doing it. She was quickly losing control and she felt like she was going to explode.

His fingers were still deep inside her, urging her to come hither, show him what she could do.

All at once, the dam burst and Katara let loose. A slick jet of juices squirted out of her, causing Zuko to squeak mid-lick and withdraw his doused fingers.

He pulled the sheet back, exposing the mess on his sheets and he looked startled yet deeply pleased with himself.

"Katara," he grunted, smearing the glittering cum off his chin with the back of his semi-dry hand, "did you just…squirt?"

Blushing furiously, the waterbender bit her lip and nodded, feeling slightly embarrassed with herself. She had never done that before, but it felt insanely good. Her walls were still clenching and jerking, releasing more and more fluid.

"S-s-sorry," she whimpered, looking away from him. "It just…sorta…happened."

Zuko lurched forward and caught his lover's chin, securing it in his hand as he straddled her. "Katara," he breathed, leaning down for a desperate kiss, "that was amazing. You taste delicious."

Katara wiggled under him, still a little apologetic and embarrassed. "R-really?"

With a smirk, he pressed his lips against hers. "Have a taste," he groaned, gliding his tongue across her bottom lip. She allowed him entrance and their tongues danced, tastes swirling around their mouths before Zuko broke his kiss and started licking down the line of her chin and to her naval.

"Mmmm," he moaned, resting his head against her tummy. "We should try that again."
