Author's Note: I've never written this much smut for one pairing before. I didn't see any of this coming (pardon the pun lol).
Also, for the record, I do ship other pairings in this series (both canon and non-canon), but what can I say, Kataang forever (girl…to quote daydream Aang lmao). Enjoy!

Katara couldn't get off.
Her legs were splayed across the bed as her husband's mouth pressed to the heat of her center, his tongue sweeping deeply between her folds the way he knew she liked it. Yet, instead of her body coursing into the heady warmth of unbelievable pleasure, she found herself writhing only in growing discomfort, and the full weight of her frustrations ultimately came through in the form of a heavy sigh.
"Aang. Honey. It's not going to happen for me. There's no point for you to keep trying. I'm sorry."
She craned her neck to peek at him over the protruding mound that was her stomach just as he withdrew himself and lifted his head to meet her look of agitation.
"Is it your back again?" Aang asked. "We could use another pillow to make you more comfortable."
"No, it's not that," Katara said. Her brow creased as she felt a sheen of sweat on her forehead, and she hastily swiped her fingers across her moist skin, grimacing at herself. "The problem is that I can't see you."
Aang's steel gray eyes simply blinked at her. "Sweetie… I'm right here."
"I know that," Katara snapped back at him, her frustrations only rising as she propped herself on her elbows in an effort to ease some of her tension. "But my ginormous pregnant belly gets in the way and blocks my view of you while you're attempting to…"
"Pleasure you?" Aang offered, a hint of a smile teasing at his lips, but Katara mistook his playfulness toward her as though it were being aimed at her expense.
"It's not working," she insisted, practically whining now. "I need to be able to see you while you're doing it because watching your head between my legs is part of what turns me on. And right now I'm not turned on. I'm frustrated and sweaty and I think I'm starting to get another cramp. And of course my complaining is only killing the mood. It's not even your fault because I know you're trying your best, while I'm being so demanding and impossible to please."
She threw her hands over her face, releasing a wail into her palms before she could help it. Not even a second later, Aang's arms were around her, drawing her into the solid warmth of his bare chest. The gesture had an immediate calming effect as her cries tapered off, bringing forth a much-needed stillness within her. Slowly, she lowered her hands and blinked up at her husband, whose warm eyes met her bright, watery ones.
"Katara," he said, his voice just as soothing as his embrace. One of his hands came up to brush aside her hair, fingers gently raking through her dark locks. "What's wrong?"
Katara's hands automatically enclosed over her swollen stomach, cradling their growing child. Her lips raised in a smile, even as a stubborn tear trickled down her cheek. She didn't bother to wipe it away as her eyes flashed back up to his with renewed fondness.
"I'm sorry," she repeated, her voice far gentler now. "You've been so patient with me through all of this. You're such an amazing husband, Aang. But that's just it. Pretty soon, we won't only be husband and wife anymore. We'll be…"
"Parents," Aang finished for her. His hand enclosed over both of hers, tattoo pointing straight up toward her. Her heart fluttered wildly when his lips brushed her forehead in a soft kiss. The way he smiled at her now, with such tenderness and devotion, made her heart melt. "I know you get tired of hearing me say this, but you're already a natural-born mother. Sure, things are going to change, but it's nothing we won't be able to handle together."
"Yeah. You're right," Katara said, smiling through a fresh round of tears collecting in her eyes. They slipped out and rolled down her cheeks before she could stop them, though her smile only widened. "You really are perfect, you know that?"
Aang chuckled softly, bringing one of her hands to his mouth to give her a grateful kiss.
"Thank you," he said sincerely. "So are you."
"No," Katara said. She cupped a hand to his face, her eyes searching his with a profound need to communicate to him, right now in this tranquil moment between them, exactly what she meant. "Aang. You're the absolute perfect partner. You're so kind and always reliable no matter what. And that's part of my frustration with all of this. Once the baby's here, our priorities are going to change. Don't get me wrong, I can't wait to meet our child, but we're going to be so busy taking care of the baby, we won't have time for much else. And when we eventually do find time to ourselves again, we'll be so exhausted that we won't have the energy to be…intimate like this as much as we want. At least, not for a while."
"Wow," Aang simply said in response, another warm chuckle behind his voice.
His hand swept to the side of her head as he leaned down and pressed his mouth to her neck. Katara tilted her head back, eyes fluttering shut as she briefly lost herself in the welcome feeling of his warm lips against her skin. He pulled back far too soon, offering her a gleaming smirk.
"I never realized how much you can't get enough of me," he said teasingly, at which point a vibrant blush ignited Katara's already warm face.
"I never said that," she protested, although it hardly seemed to matter in the slightest as his smirk didn't budge, which only managed to unnerve her all the more. She sharply turned her head away in an effort to force down her embarrassment. "Whatever. If it didn't take me such a long time to get up on my own, I'd storm right out of here just to prove my point."
"Oh, you would, would you?" Aang asked, his tone so playful that it was obvious he'd already called her bluff. Her annoyance at that fact dissipated in favor of a pleasant shudder that rushed down her spine when his fingers grazed her ear, his voice dipping seductively as he said, "That's too bad, because I'm pretty sure I just figured out a way to fix your problem of not being able to watch me while I…please you."
Katara could already feel a moan working its way up her throat, ready to burst from her at just the thought alone. She swallowed, her muscles secretly clenching as her desires spiked.
"You did?" she asked, her voice now sounding small in the midst of her weakening resolve.
"Would you like me to show you?" Aang asked.
"Yes," she answered instantly, not even bothering to hide her eagerness.
With his arm securely wrapped around her waist, Aang got up from the bed and placed his other hand into hers, carefully guiding her to her feet. Once she was upright, he led her over to the floor-length mirror that hung from their sliding closet door, just outside the adjoining bathroom. Katara stood there in a stunned silence, watching intently through the mirror as Aang released her hand and lowered himself to his knees in front of her, his head hovering over her protruding midsection. Her eyes widened in wonder when he gripped a hand to the back of one of her thighs.
She shrieked when her foot suddenly slipped off the ground as Aang lifted her leg and draped it over his shoulder. She blinked, still standing straight thanks to his firm grip holding her in place. Another delightful shiver rippled right through her when he placed a kiss to her inner thigh. Finally, he turned his head to meet her gaze through the reflection in the mirror, his pale skin glowing beneath the light from outside that seeped in through their bedroom window.
"Does this work for you?" Aang asked.
Katara heard herself release a soft, captivated breath, and a gracious smile stretched across her face. "This is perfect. Thank you."
His warm grin took on a far more seductive quality as he turned away to direct all his attention to the earlier task at hand. She kept her gaze fixated on him, eyes following the beautiful blue line that hugged the middle of his back, only to jolt upright when his tongue swept inside her without any warning. Her leg that hung off of his shoulder reflexively tightened around him for support as his tongue dipped into her center, giving a sweeping lick between her wet walls. The moan she'd been holding in tore from the back of her throat, elongated with a heightened sensitivity thanks to her pregnancy hormones. His tongue swept upward and back down again, swirling a trail deep inside her, slowly working its way up toward her most sensitive spot.
She caught her own reflection in the mirror, amazed by her own aroused appearance between her deeply flushed face and widely dilated pupils. Her gaze promptly dropped again to focus on the subtle motion of the back of Aang's head, the way it tilted as he sensually moved his lips along her slick walls. Another high-pitched moan ripped from her throat when the tip of his tongue flicked across her delicate bundle of nerves. Her thigh quivered against his shoulder as her insides clenched, the tension within her building deliciously when she felt the suction of his lips clamping down on her.
"Aang," she cried out, a burst of electrifying pleasure splitting through her.
Her vision grew hazy in her thickening cloud of ecstasy. His tongue swept across her clit again and again, making every single muscle in her body constrict and tremble all at once. Her leg flexed around him as her walls tightened, veering recklessly toward her imminent release. Each one of her breaths grew shorter and shorter until she became so dizzy her knee started to give out from beneath her. Aang's hand on her waist slid down to her standing leg, holding it there to ensure that she wouldn't fall, allowing her to solely concentrate on the mounting pleasure as his tongue continued licking up and down between her wet folds.
When his mouth brushed her clit again, it all became so much that Katara's entire body lurched, then stilled, and a wave of heat exploded from her in the most powerfully intense orgasm she'd ever experienced. Her fingers and toes curled as her walls pulsed, his tongue still sweeping inside her as she moaned his name with a roughened texture of gratification. When it was done, she was left panting helplessly, barely able to understand how she was even still standing upright as her heart hammered away in her chest.
"Oh, Aang. Wow. Sweetheart, that was… I…"
She struggled to speak, let alone form a single coherent thought. As she gasped for air, she gradually released the impossibly tight grip she only now realized she'd had on him this whole time, her hands having left tangible marks on his skin. Meanwhile, Aang grasped her by the leg that had fully wrapped itself around the back of his neck, returning it back to the ground. Finally, he rose to his feet, eyes shining at her with sheer love and painstaking arousal.
"I admit it," Katara said. With a shameless smirk, she wound her arms around the back of his neck. "I can't get enough of you."
She crushed her lips to his, and he released a deep groan into her mouth, a sound so guttural it surged her need for him, as did the taste of her fluid on his tongue. She was generally repulsed by a lot of things nowadays due to her pregnancy hormones, but this particular taste was far from one of them as it only served as a reminder of the mind-blowing pleasure he'd just given her.
"Oh," she moaned, breaking the steamy kiss when she felt a hardness conspicuously prodding against her thigh.
Aang gave her a sheepish grin, yet there was a sultry twinkle in his eyes as he confessed, "In case it isn't obvious, I can't get enough of you, either."
Katara smiled back at him in appreciation. She brought a hand to the back of his head as their lips met again, ravenously moving against each other in growing need. Her other hand dipped into the waistband of his underwear, wrapping her fingers around him. He broke the kiss with a deep moan, eyes glazing over, and she only smiled wider, vigorously working her hand up and down his length with the goal of bringing him to a reckless release of his own. Yet, just as he twitched in her palm and let out a quivering breath, he found the willpower to grab her wrist, letting her know he didn't want to finish quite yet. And so, she withdrew her hand from him, more than willing to see what other plans he clearly had in mind.
Aang momentarily released her, giving himself the room to remove his underwear before they were right back in each other's arms. His lips found her neck again, eagerly nibbling her tender flesh. Katara busied herself by pressing her mouth to his jaw, then his cheek, leaving a hot trail of kisses across his skin until she reached his ear, where she gave him a slow, sensual lick. The way his whole body shivered against her made her heart pound.
She squealed in surprise when, out of nowhere, his hands cupped her backside. Her hands automatically tightened around him as he hoisted her into his arms, pinning her between the wall and his muscular body. He didn't strain at all in holding her up, even with all the extra weight she was carrying courtesy of their unborn child. He simply stood there, giving her time to adjust to this new position as she wrapped her legs around his waist and placed her hands on his shoulders.
"How are you able to…" Katara started, only to trail off, staring at him in awe as she tried to make sense of it all. "I mean, I'm so big right now. And yet, you just…"
She realized she was at a loss for words again, so instead of trying to comprehend it, she simply pressed her mouth to his in a deep kiss, sweeping her hands to the back of his head. His firm grip on her only tightened, and when they came up for air, she stared at him through half-lidded eyes, exhaling in amazement.
"I guess I sometimes forget how unbelievably strong you are," she said at last.
"Well, I am the Avatar," Aang said in a tone that matched the unabashedly cheeky grin that stretched across his face.
Katara brought a hand to the side of his face, stroking her palm down the slope of his cheek, across his defined jaw, underneath his chin. Admittedly, she also sometimes forgot that he was two years younger than her, as he'd matured so much over the years, not only physically, but emotionally. He was as much a calming presence as he was a trustworthy protector, a constant pillar of hope. He was…
"My sweet husband," she said adoringly, lost in his eyes that shimmered back at her such glowing affection.
"That's my favorite role of all," he said, matching the sweetness in her voice. His smile softened when his eyes dropped to her stomach. "Although, I can think of a new role I'm just as excited for."
He bent his head, placing a kiss onto her outstretched abdomen, and a wave of emotion hit her all at once. Placing both hands on either side of his face, she pulled him into a passionate kiss, reminiscent of the way she'd kissed him all those years ago when the war was finally over, pouring all the love she had for him into it.
When their lips parted, their eyes locked onto each other in a deep gaze, and her muscles clenched in anticipation. She felt his tip graze her entrance, wet and waiting, when finally, he pressed into her. They moaned in unison as he thrust his hips forward, filling her completely. She could feel all of him, the way he throbbed inside her, the warmth of her surrounding him, and she groaned as he moved inside her, sliding in and out against her slick walls. His breath tickled her neck as he lowered his head to press his mouth to her collarbone before grazing it between her breasts.
Katara's legs tightened around him as his thrusts grew harder, his hands digging into her warm flesh beneath her to support all of her weight. Her own hands dug into his shoulders, growing sticky with sweat. Unable to resist, she dove forward and swiped her tongue across his neck, tasting the salty tang of his skin. He moaned heavily against her as she worked her mouth over his neck, and the pacing of his thrusts only increased, creating an undulating rhythm between them.
Eventually, she withdrew her lips from his neck to meet his mouth once more, stroking his tongue with hers, relishing the pleasure-filled noises he made. He drove into her so deeply that it sent her hurtling toward another staggeringly intense climax just as he, too, exploded inside her. They both released muffled moans as they rode out the waves of their rapturous finish, leaving the two of them physically spent.
"Wow," Katara breathed, beaming at him in complete and utter satisfaction. "If I weren't already pregnant, that definitely would've done it."
Aang released an amused exhale in response, dropping his head to her shoulder as he panted against her sweating body. She hugged him to her, making sure not to cling too tightly so that he still had enough room to breathe. When he finally lifted his head to meet her warm gaze, she leaned down and pressed her lips to his forehead. He then tipped his head up to bring his mouth to hers, and she held his face while he carried her back over to their bed.
As they relaxed into one another, their eyes drifted shut, and Aang brought a hand to gently rest on top of Katara's stomach again, just as she placed one of her hands on top of his.
"Thank you…for always being so strong for the both of us," Katara whispered.
"You're the one who gives me strength," Aang whispered back. "My incredible wife… I'm so in love with you."
"I'm so in love with you… My sweet, perfect husband."
They fell fast asleep with their hands protectively encased around their soon-to-be firstborn, the start of their family, a symbol of their eternal love for each other.
