Blake and Castiel
"Snow angels," Blake said. He explained that when someone did that, after they got up, the imprint in the snow looked like the traditional image of an angel. "It's kind of silly. But it's also kind of fun." Blake shrugged.
He knew Cas was being coy. he knew exactly what Blake was implying. The snow was fun for a while, but there were so many other things they could be doing. Things that created warmth for Blake, instead of cold.
