Once more her skin began to tingle when he touched her. She knew she should pull away before they ended up doing something they would regret. She knew this was how things had gotten so screwed up at the shelter, to the point that Zuko had left rather than deal with any of it. He had just told her that he'd gone through a breakup before arriving here. Anyone with half a brain would realize that letting this continue any further would only lead to disaster.
So why, then, could she not seem to stop?
It was as though the anger she'd been feeling mere moments ago had been replaced with a desire, a need to feel close to someone familiar. Aang was here, of course, but she could never see him as anything more than a very dear friend. A brother, of sorts. Zuko, however... he was different. Forbidden, which made him all the more appealing in some strange way.
Her hand moved from his lips to the back of his head, fingers dancing across the nape of his neck as she finally decided she'd had quite enough of looking and mere touching. Another half-step closer so their bodies were fully against one another and Katara was on her toes, lips meeting his in a featherlight kiss.
