Hey anon! Mod Fable here~ Thank you so much for our first prompt! I've decided to write something for it (the idea was just so interesting), but this is just a reminder that if your prompt doesn't get answered by a mod, we'll still post it for others to take a shot at.
“Aang! What are you doing— we’re going to get caught!” Aang rests his head on her shoulder and closes the door to the closet he’d pulled her into. His breath sends shivers down her spine, and the hand sitting just below her breast turns the shiver into a spark of breathless anticipation. Then she takes a hold of herself and glares at Aang.
“We aren’t hidden nearly enough to do anything right now, and you know that Toph is going to be hunting for us at any moment. She’s too light of a sleeper to let us get away with doing anything this-” she continues, only for Aang to interrupt by running a hand down her back and scooping her into his arms. Her hands tangle into his robes where the line of cloth and fever-hot skin meet.
“Don’t worry about it, love. I have an idea,” Aang murmurs, his nose traces down the outside of her ear, and she avoids giggling by tucking her mouth into his neck as best as she can. Her muffled giggles become a stream of tiny kisses pressed below his earlobe that make his breath skip in his chest. One of his hands cups her jaw, tilting it up, so that he can kiss to the corner of her lips.
“Either way, you’re not going to get away with teasing me all night like that.”
Katara flushes. So he’d noticed after all. Then she realizes that Aang’s legs are crossed and tucked beneath them and he’s pulled her firmly against his chest. She’s about to scold him, there’s no way that this won’t alert Toph. And if Toph woke up, she’d probably go get Sokka, for maximum embarrassment as a punishment for interrupting her sleep. Then Katara takes a second look...and they’re not touching the ground anymore.
“Would you look at that?” Aang chuckles, and Katara turns in his lap. His eyes are dark, and Katara’s heartbeat throbs through her body like a tidal wave. “We’re not going to be interrupted— so it looks like you have all the time in the world to make it up to me.”
He’s right. It doesn’t look like Toph will discover what they're up to any time soon. In fact, none of their friends will be any wiser to what’s happening. They are suspended in the breeze that Aang has swirled beneath them, and insulated from the world by the walls of the closet.
"Now that's a creative solution... will you be able to keep this up, though?" She hooks her other leg around his back and turns to face him completely. It’s disconcerting to see nothing under them, but the gentle bob of the air below bounces her in Aang’s lap, and her thighs hitch and drag against his sides. The sensation drives any thought of falling from her mind, and her hands tighten on his robes again, her fingernails digging into the skin beneath.
Aang grabs her hips and pulls her tight against the growing bulge in his pants. One of his hands tangles into her hair, cradling the back of her head, the other sliding down over her hips to squeeze her rear. "What do you think?"
“I’ll believe it when I see it, Avatar,” she says, grinding down against him. His head tips back, and she takes the opportunity to press her advantage, kissing his exposed throat. Aang’s hips rock perfectly in time with the turbulence of the air, and Katara gasps.
“I guess I’ll just have to prove it then.”
