Ooooo, someone draw this wonderful image!
'Cas panted, sultry navy eyes sparkling as he pulled back with a sweep of his shoulders, wings arching into a stunning display as he sat up. Regal, magnificent, royal. Dean saw galaxies in those eyes, saw passionate indescribable. He sank back, watching as Castiel pulled away his belt with a flare of the wrist; flicking open the buttons of his jeans. Sure hands were tucking his jeans open, and boxers out of the way before Dean even realized Castiel had every intention of riding him like this. Dean clothed with a naked Angel topping him; the thought itself was going to fuel his fantasies for years.'
