He wasn't about making promises he couldn't keep, saying pretty words for the sake of hearing his own voice. Klaus had needed comforting, reassurance that he wasn't powerless and Bill only gave it to him because he knew it was true. It wouldn't be easy sharing a wand, but maybe they could find another, maybe they could find a place where they could find Klaus's wand.

He wasn't usually one to finish so fast, but he was so caught up in it, in the heat and grip of his body and the moment. Klaus' hands slid into his hair and he groaned around him, enjoying every second of it. He was gorgeous and Bill watched with hooded eyes as he came apart, arched and so pretty.
Standing back up he dropped his head down onto Klaus' shoulder and laughed, all soft and melted at the edges. "I'd bloody well hope so, love," Bill told him.
