Somewhere along the line-and Dean's not sure where-Cas became a blowjob god. Some of his moves Dean recognizes from porn or his own experiences but a lot, if not most, of it can only be pure Cas. Dude's a fucking blowjob savant, he can't operate a toaster but he can get Dean from noodle-limp to hard as fucking steel in 6.4 seconds. Cas even watches porn to see if he can find any tips he doesn't know about yet and Dean's pretty sure Cas' porn collection rivals even his own, albeit with quite a bit fewer women.
He sucks; he licks; he moans, hums, kisses and swallows around Dean, massaging his balls with one hand while the other teases Dean's entrance. Add that to the fact that angels don't need to breathe and Jimmy has no gag reflex and Cas can deep throat with the best of them. Better, even.
He likes for Dean to lose control and start fucking his mouth, his cock thrusting down Cas' throat while his hips slam into Cas' face so hard that, if he wasn't an angel, he'd have a broken nose and bruised cheekbones. He loves the sounds Dean makes as he spills down Cas' throat, a harsh growl that sounds as if he's the one who just got throat-fucked followed by breaking off into harsh panting as he pulls out and paints Cas' lips with his cum, then watches as Cas can't help but lick his lips. Dean always moans at that point, and pulls Cas closer to him, faces level so that he can kiss Cas and taste himself in his angel's mouth.
Thanks for reading! Please review (it makes writers happy. Happy writers write better smut.), I just started writing M/M smut so I'd love some [constructive] criticism.
Reviewers get a Popsicle in the shape (and flavor) of their favorite character. Or Misha Collins. Misha Collins is awesome.
