I was challenged to do a FINGERS IN HIS MOUTH FRIDAY drabble for CAITH sooooo here’s 200 words of fingers in mouths. explicit smut under the cut!
Dean can’t stop looking at Cas’ hands. He tries not to, really. Tries to remind himself they’re often smeared with mustard or stained with nicotine or that his nails are nervously bitten down around his cuticles. But he doesn’t care, it doesn’t detract from the fact that he likes them. He likes the shape of them, how rough they are. How he’s bigger than Dean, fingers longer, thicker. Palms square.
In the end, Dean is the one who initiates it. He’s got Cas in his fist, working him over quick and dirty before he has to go get Adam. They’re crammed up on the couch and too close together. Cas touches Dean’s face, his jaw, and then one of his big, broad thumbs swipes over his bottom lip. Without thinking, without deciding, Dean takes it into his mouth, sucks hard.
Cas’s eyes go wide above him, and when Dean opens his mouth all the way, Cas swaps his thumb for two of his fingers. They’re big. They fill Dean's mouth completely, press against the inside of his cheek, and the swell of his tongue, and deeper, too, until Dean gags softly, drooling a little, and Cas spills himself with a groan in Dean’s fist.
