Summary: Castiel licks Dean's tattoo.
The motel room was dark. The only sounds were the whir of a rusting air conditioner and the hum of Magic Fingers. The air was scented with arousal and sweat.
As Dean's fingers dug into Cas' shoulder, Cas traced the outline of Dean's anti-demon possession tattoo with his tongue. The intricate almost delicate lines, as black as a demon's eyes, held a powerful magic that made Cas' tongue tingle.
Cas wondered what it would be like to have some kind of protection from your enemies. He knew no mark of ink would protect him from the wrath of his brothers.
