Grooming

Dean's been an angel for three days now. He's still getting used to the weight of wings between his shoulder blades and feeling as if he could spontaneously combust at any given moment, but it's not all that bad. And Castiel seems to be inexplicably happy that Dean now has Grace like him, is a bottled force of power, strong and immovable just like Castiel himself.

Dean doesn't really understand that, but he's not going to complain. Not when the angel smiles more often than not now and can't seem to keep his hands, or his wings, off of Dean.

The only problem is, Dean is the equivalent of a baby angel; a fledgling. He's new to everything and daftly inexperienced thus making him a little wild. He's also impatient. But Cas, who has taken it upon himself to teach Dean the ways of the angel, is a fervent teacher and so Dean puts forth his best effort to learn to be the best damn angel Castiel has ever known.
