As Yamato pushed him back Kakashi spared the few seconds of pause between them for a breath, and as another set of lights erupted into the sky the copy-nin raised his hand to his face, fingers hooking in the fabric across his nose and tugged it down to rest under his chin.

He knew Yamato would want to look at him, would want to reassure himself and reassure Kakashi, but Kakashi didn't want questions now.. He didn't want to think or wait or do anything that wasn't pressing his lips against Yamato's without the barrier of his mask, and so that's what he did. He gave Yamato that crucial moment to look into his open eye and to look at his face, to see that he meant this, and then their lips were together again.
