This is the start of chapter 2.

Aang found himself thinking that he could continue on like this forever; tasting Katara's tongue, massaging the mass of her breasts and squeezing her pointed nipples. It didn't take long for him to understand how wrong he was.

Katara could feel his member pressing against her through their clothing and it was driving her wild. She pried Aang's reluctant hands away from her chest and slide his arms around herself, pushing them down beneath the fabric of her skirt, cupping her cheeks. She matched the position and gave him a light squeeze before running her fingers all along the inside of his belt line. When both her hands met at the front of him, she giggled as his whole body reacted. She spread back out to the sides while plunging her hands deeper.

With Katara's hands staying in place, she bent the water to pull Aang away from her, sliding the last of his clothing off. His erection popped out and bounced up and down in front of her face and she giggled again.

"Katara.."

"Is there something in your pocket or are you just happy to see me?" Katara quipped.

Aang was pulled from his trance and fixed her with a confused expression. "Katara my pockets are.. you just took my-"

"Shhhh." Katara quieted him and reached forward to grab his shaft, taking pleasure in the noises he made with each movement. She bent the water to position his legs just over her shoulders, and slowly worked his cock around in circles a bit, just playing around with it before starting to stroke up and down with both hands. "How's this?"

"Oh Katara, that feels.. OOOOOHHhh." Words escaped him as the water supporting him pushed him forward. Katara met his member with her mouth and his mind went blank.

When Aang mediated, he often thought of himself as existing in only a single, tiny point, just behind the third eye in his skull. In that moment, he felt very similar, except he was split in two. There was the point in his head that he was so familiar with, and the rest of his being was inside Kataras mouth and throat. It was like the rest of his body was asleep or in a daze, but his mind and his penis were more awake and alive than they had ever been. He tried to speak his appreciation while Katara worked but all that came out were animal grunts and unintelligible groans. His hips bucked involuntarily.

Katara pulled completely away at once, breaking all contact with a giggle. Aang looked at her with a wild expression, like he had just woken up and had no idea where he was. She slowly rolled over onto all fours and waved her whole lower half of her body back and forth.

When Aang didn't immediately move forward to meet her, Katara pushed him from behind with the water. He lurched forward and caught himself with both hands on her ass. "I told you Aang, these clothes are terribly uncomfortable when they're wet. Won't you be a gentleman and help me out of them?"

Still in awe, Aang obliged. As he peeled the wet cloth off the roundness of Katara's ass he bent forward and began kissing the small of her back. He worked his way down, kissing his way around her curves. He hesitated just a moment, unsure of what to do - then decided on one long sloppy lick from the nub of her clit all the way to her puckered asshole. He had absolutely no idea what he was doing but she seemed to like it.

Katara perked up with a soft sound and looked back at Aang over her shoulder. He looked a little concerned, clearly looking for direction. She gave him a warm smile, hoping to reassure him. "That was nice, just not what I was expecting. We can work on tongue skills later." She dropped the smile and looked more intensely into his eyes. "I want you inside me now."

Katara took control of him with the liquid surrounding them both, and positioned him right behind her. The very tip of the head of his penis was pressed between her lips, not quite inside yet. When Katara stopped pushing him forward, Aang pulled his gaze up from their genitals to see her face. Her expression was soft and her eyes were half closed. "Oh that feels nice. I've thought about this a lot, Aang."

Wow. Aang loved hearing that. "Me too.." He felt like he should have more to say but his mind was a mess, simultaneously sluggish and racing. Full sentences seemed beyond him.

"Push it in, Aang." Katara instructed eagerly. "Slow at first. Gently."

Aang obliged. He slowly pressed his hips forward and felt the resistance lessen suddenly as he entered her properly. Katara let out a gasp and Aang went completly still, terrified that he'd done something wrong.

"It's ok, Aang. It's perfect. Slowly, just like that."

So Aang pressed forward again, slowly. Katara continued making sounds and Aang took joy from all of them. A little bit at a time he pressed forward, then stopped, then pressed a little more.

His hips wanted to oscillate back and forth but he didn't want to press too deep too suddenly and hurt her. So he began a slow, shallow stroke using a little more than half of his length. Katara let out a long low sigh that let him know this was good. She began to move in rhythm with him, and together they slowly built speed.

Each thrust was going just a little bit deeper, and Katara's pleasure was getting a little bit louder. Finally, Katara pushed back fully and took the whole of him in. She kept her hips pressed back now. Aang could feel her walls squeezing and relaxing around him. He wasn't going to last much longer.

"Aang I'm almost there already." She kept him deep inside her and moved her hips in a circle. "Oh, god that's amazing." She raised them both up with the water around them to make the movements easier. She rotated them just a bit so that she was more upright. Continuing to gyrate, she reached one hand back over her head to run it over his smooth dome, while the other had reached lower and found one of his hands. She guided him around to her clit and used his fingers to make small circles there, slowly at first but quickly accelerating.

Katara continued getting louder and Aang felt her contract around him even tighter. Her legs shook and her insides spasmed against his member. Her movement lost its rhythm as she bucked uncontrollably. Finally, she slowed and relaxed. Aang was in awe at the beauty of her pleasure and felt himself continue to pulse against her walls. "Did you just.."

"Yes, Aang. That was amazing. I mean, I've done it for myself before but that was- Oh!"

Without thinking about it Aang had taken a long full stroke and replaced his cock deep inside her. "Sorry! Is it sensitive now? Should we stop?" Even as he asked his continued to absent-mindedly rock back and forth, just a bit.

"It is sensitive but we definitely should not stop." Katara gathered her hair and leaned forward again onto all fours. "It's very sensitive, but I'm not as tight as when we started either. Show me what feels god for you."

He took a few cautious strokes, but planted the last of them all the way against her as deep as he could go. She let out a sound that was clearly pleasure. That was all he needed to hear to drop his inhibitions.
