Aang wakes to the soft chirp of crickets and the rush of the moving river. His friends are all around him, as always, snoring softly in the warm night. This time, though, Katara is beside him. She's facing away, curled up so that her backside presses gently into him. He realizes this is what woke him up, her body against his side.

He turns, curling himself around her. She's warmer than he expected, and softer. She presses gently back, tucking into him in her sleep. He revels in her heat, in her closeness. Her dress has ridden up in her sleep, and his hand grazes up her leg, coming to rest on the slight swell of her hip. She moans softly, and Aang realizes he's hard against her. He takes a moment, focusing on his breath, on the still night, Zuko at his back, Katara's soft breath before him. Then he presses his length, gently, barely, against her. Her breath catches audibly, and she pushes back into him.

Her dress is almost up around her waist now, and her hand is resting lightly on his thigh. It suddenly takes all his focus to not grind against her. Her hand though, it's drifting. Up and down, fingers flexing and releasing. Aang wets his dry lips. When she grasps his thigh more tightly and presses her firm ass back into him, he has to stifle a groan. With her dress twisted up this way, there's not much more than a scrap of cloth covering her. Aang hooks his fingers into the waist of her underclothes, dragging them down just over her ass. The swell of it under his fingers makes his cock twitch.

When she is finally bare against him, he lets his hand drift up between her legs. She rocks her hips against his drifting fingers, and she's so wet they slip inside her, just a little. Aang's breath catches, and he has to stifle a moan. His fingers are barely inside her, only up to the first joint, but she grinds gently against them and breathy moan leaves her lips-

"Aang-"

-and he can't anymore. Can't hold back. His other hand hooks into his pants and he wriggles out of them to push himself into the soft warmth of her ass. Katara is still rocking sleepily against his fingers, inviting them deeper and deeper into her. Aang presses his mouth against her bare shoulder. This is more intense than anything he's ever felt, like he's falling, like he'd give anything to be nestled tightly within her.

When she arches her back next, Aang breathes out her name and his cock is at her entrance. Her breath is suddenly quicker. She shifts lightly against him and that's all it takes, his head slips inside her.

Aang lets out a loud moan as he inches into her dark warmth. Should he wake her? He didn't mean for things to get this far. But now that they have he feels like he'll die if it stops. His cock presses, centimeter by centimeter, up into her wetness. He moans again. He can't help it. Her breath is faster now, and there's a little twist to it as she grinds back onto him. He holds off as much as he can, letting her grind on his head, the barest tip of him penetrating her.

Suddenly, a soft snort from behind him. Zuko shifts in his sleep, tucking deeper under the blankets. Aang freezes for several long moments. When Zuko doesn't move again, he presses the barest inch forward, and is rewarded by Katara's sleepy press back. This time she takes him a few inches deeper into her. Aang has to pant for a few moments, acclimating. There is resistance in her now, a tight wall that blocks him. He gives a few light thrusts against it and nibbles her bare shoulder.

Katara turns her face toward him and he can see her hovering between sleep and wakefulness, her breath hot breath on his face. His arm tightens around her. She lets out a breathy gasp against his cheek, and he is past the point of no return. Aang presses forward, slowly, finally, sheathing himself in her depths. He moans, and it is into her ear, and he doesn't care. Her breath is somehow high pitched as she twitches against him.

Aang pulls slowly out and the cool air nips at his wet cock. Slowly, slowly, he sheaths himself back into her. Katara lets out a deep shuddering sigh as he does, but he can barely hear it. Is this how sex always feels? So lost and so joined with? Some reflex in Aang takes him and he jerks a few small thrusts into her. His hand drifts up to cup her breast, and cupping is so far from enough. He slips into the opening of her dress and his fingers brush against bindings. He works his hand between the strips of fabric, and finds the soft curve of her breast. His cock throbs in response. He cups it for a moment, then he drags his fingers over her nipple, catching it between them, dragging his nails over it. His ministrations are rewarded with sharp bucking from Katara, and Aang groans at the wet heat enveloping him.

He thrusts back, harder this time, pulling out and sheathing himself firmly in her. She mewls at this and Aang wonders how far he can take this before she wakes up. He sinks his teeth into her neck, he can't help it, and she thrusts back harder against him.

His rhythm is fast now into her slick, tight body. He rolls her the peak of her breast between his fingers. He pulls her dress further open, letting her titls spill out of it, hungrily drinking in the sight of her soft breasts, her hard nipples.

Suddenly, he can't take it anymore, and the moment he realizes this he is already cumming, shooting hot, sticky ropes into Katara's waiting pussy. She arches her back, as though to ensure she would take all of it into her.

Aang slowly recovers his senses, becoming aware again of the sounds of the forest around them, his sleeping friends just an arm's reach away. He eases his softening cock out of Katara's body, and a gush of cum flows out. He sits up to watch his seed flowing out of her, and almost begins to harden again. Instead, he gently tugs her clothing back into place before slipping back behind her, curling his body around her, and falling deeply asleep.
