"Kate--" He starts, his hands sliding up for a moment to rest at her shoulders, as if he's thinking of pushing before he's sliding them down to rest at her hips, holding on tight. There's a gasp that leaves his lips as he tips his head.

"You're-- not thinking, you know." Then again, neither is he. Not really.
