From a prompt from
domina_malfoy:
"I guess those angel robes don't have pockets," Dean says.
"Why would we require pockets?"
"You could stand to take some Chapstick along. You're always chapped, dude." Dean lightly draws his finger across Castiel's lower lip, from corner to corner.
Castiel shivers, the most purely physical reaction Dean has seen from him.
"Now you try it."
Castiel's strokes two neatly manicured fingers over his own lips.
"Now mine." He draws in a ragged breath as Castiel feathers his fingertips over his lip. "See?" he whispers.
"Why does it matter?"
Dean leans in toward Castiel and kisses him, gently exploring. "This."
