"Mmm," Katara murmured as she snuggled closer into Aang's warm embrace. He smiled as her hair tickled his nose. Aang loved her hair. It had a certain smell to it, like a sweet flower, with an undertone of vanilla. The scent often rode the air to him, and he found himself wanting more.
He also loved the feel of it, and he could stroke it for hours, which is what he lay doing absentmindedly. Her hair was soft, but when he got to the ends it became more coarse, and at night he noted it was prone to be a bit more tangled.
He continued to run his fingers through her hair, working out the knots and making it easier for himself to stroke the entire length of her hair with no interruption of having to work out a knot.
Aang did this for a while, until the effect soothed him so his eyes gently closed, and he drifted into subconscious, hand still halfway through brushing Katara's hair.
