Hands
Aang leaned against Katara, his breathing shallow. She knew he would make it, it would just be a painful ride. She gently slid out from underneath him and layed his body onto the sleeping bag. She got up and went into her own tent, she was exhausted.
She took everything but her undergarments off and crawled into her own sleeping bag. She couldn't believe it, the Earth Kingdom had fallen. She felt her anger rise, how could that spoiled prince do this? Doesn't he care about anyone but himself! Too think she almost helped him!
He was probably sitting at some banquet right now, getting drunk while women threw themselves at him! He's probably got his hair in some kind of ponytail again and sitting around without his shirt on like so many other times.
Katara lie in bed, too angry to sleep. She looked at her right hand, the one that had been on his face. She thought of the time his hands had grasped hers when she ran from the pirates. How he had dragged her over to the tree and tied there, his strong hands grasping hers, making sure she couldn't waterbend.
Slowly, Katara slipped her hand in between her legs. She closed her eyes and thought of Zuko. His strong hands moving sudden and roughly through the air as fire shot from them. The way he moved them when he commanded his men. She groaned as she reached further, finding the right spot.
She thought of the time he picked her up and set her on the sheer-shu, she couldn't feel his touch then, but she had secretly wished she could. She thought of the way he made the fire whip, taking her techniques and finding a way to make them his own.
She bit her lower lip as she thought of what other techniques he might have. She imagined her small, feminine hand was now his. Strong and forceful, warm no matter how cold it might be. He searched her, explored her, his hands knowing just were to touch. He moved them faster and stronger as the sensations intensified. His hands doing everything right until...
Katara gasped, her back arched, her pulse beat in her ears. She straitened out, shuddering. Lying still for a few minutes, knowing that the slightest bit of friction of her thighs would be too intense. She rolled over and tried too sleep, but she knew his hands would haunt her dreams.
