1. Wing Kink
Dean stretched out his hand to feel the silkiness of the feathers in his fingers. Cas had never made this part of himself available to the hunter before, but Dean could see how they had always been there; sheltering him when he needed them. There was something profoundly sexy about seeing his angel this way- so open and exposed. The angel kept his eyes downcast, waiting for whatever Dean might say in response to this new oddity he had introduced.
"You're beautiful, Cas." He whispered, ruffling the ebony wings with his ever tightening grip.
Castiel shuddered as tears filled his eyes and his hands sought to bring Dean's lips to his own. They made love right then, with the tickle of wings playing on Dean's flesh; moving their bodies as one.
2. Dom!Cas Sub!Dean:
He could taste Dean's blood in his mouth as their lips met again; his tongue darted out to lick the crimson liquid as Dean moaned in response. He should not have bitten down so hard, but there was something about the hunter that made him so angry and so happy at the same time.
Dean had never complained about the violent way that Cas liked to take things in the bedroom and often times he enjoyed giving himself over to the hands of the hunter for just that purpose.
But tonight, in this alley, with Dean pressed hard against the brick wall; he couldn't stop himself. He lifted the hunter's legs to wrap around his waist as he trusted upwards pressing their bodies as close together as possible. Covering Dean's mouth with his hand, to prevent them from being discovered, he worked fast, bringing them to the edge and tossing them over together as one shuddering, panting mess.
3. Sub!Cas:
"Say it, Cas! I need to hear you say it." Dean grabs the scruffy locks at the base of the angel's neck, pushing himself deeper inside.
Cas knows what he wants to hear; knows how his body is aching to say it and give in to the waves of pleasure that will rack his body when he does, but he just can't. Not yet. As much as Dean needs to be wanted and obeyed, Cas needs to be broken and bruised this time.
The hunter reaches around, stopping the frantic rhythm of the angel's hand working himself into climax, refusing to let him continue until he has satisfaction of his own. It is a game they play; each one acting out his role to bring the other to a place of pure lust before surrendering. Cas couldn't really be stopped by the mortal man if he didn't want to be, but he lets Dean have his moment.
The hunter's teeth bite down into the milky flesh of his lover's neck and finally Cas cries out, "I need you to fuck me, Dean, fuck me so hard!"
The pace quickens as they move in sync, one thrusting into the other as the hunter strokes his lover's cock in time with his movements. As the final pulse weakens them; returns their breathing to normal they wrap their arms around one another and whisper I love yous into the darkness.
