Other than a pretty vague allusion to an event in 6.10, no spoilers.
Porn, basically.
Even with the whorehouse, Dean had never really thought of Cas as a sexual being before.

I spammed my poor feed with this on Twitter. Sorry, guys. Thanks for putting up with me! It's cleaned up and finished now. Thanks go to krystalicekitsu for giving it a look over once I'd salvaged it. <3


Once Dean gets the thought in his head, it's hard to get out: Cas—Castiel—kissing. Even with the whorehouse, Dean had never really thought of Cas as a sexual being before. But now he can't get the image of Cas' mouth on someone else's out of his head, keeps seeing Cas’ fingers slipping through hair as he holds and kisses and takes. It’s there when Dean closes his eyes, and suddenly all he can see are Cas' wide eyes looking up at him, Cas' fingers undoing his belt. Cas' hands pulling Dean's cock from his pants. That mouth—and he doesn't know why he didn't see its potential before—wrapping around him, so hot and perfect and—

"What are you thinking about, Dean?" Cas asks, the mattress shifting under his weight.

Dean startles, his eyes flying open. Cas is beside him, body turned toward Dean's, and the look on his face...There's no way he doesn't know exactly what Dean’s thinking. Feeling his skin heat up, Dean opens his mouth to protest, to apologize, to do something, but before he can get a word out, Cas closes the distance between them, mouth hard and insistent against his own. Dean groans in surprise, his mouth slipping open more when Cas tongues at his bottom lip. God, it's good. Everything Dean had imagined and more. He doesn't know where Cas learned to kiss like this, or if it's an inherent talent. He doesn't care, not when Cas is using his powers for good, not when Cas is using his powers on him.

Cas' hand is on Dean's chest, the other gripping his arm, and that’s not enough, not enough at all. Dean reaches for him, pulling Cas down hard against him, kisses him until Cas is shifting against him, breath coming hard in hot gusts across Dean's face. Cas’ eyes are dark, his lips pink and full, and Dean wants...he wants...

"Yes," Cas says hoarsely, "yes." He pulls away, and everything within Dean screams no, but then Cas is moving down his body, scooting down the bed. His fingers find the fly of Dean's jeans and work them open, slipping inside until there's skin on skin, Cas' hand wrapping around his cock.

"Cas," Dean groans, blinking at him stupidly. He’s not sure where this came from, how they got here so quickly. "Are you sure?"

Cas looks at him, sharp and dangerous, a force to be reckoned with. "Don't ask stupid questions," he growls, and then he's pulling Dean's cock free and his mouth is on him and Jesus fucking Christ.

Dean jerks upward, and Cas' fingers come up to press against his hip, holding him still as his other hand holds Dean's cock steady. His mouth is hot and wet, slick. Reaching for him, Dean slides his fingers into Cas' hair, holding on as Cas' sucks, licks and kisses and swallows around him. Dean’s skin feels too tight, his heart racing, and it's all he can do to keep his eyes open but he doesn't want to miss this, doesn't want to miss any of this. If he's going to close his eyes and see Cas later, he's going to close his eyes and see Cas doing this.

Cas pushes against Dean's hands, lips stretched around Dean's cock. He pushes until he's at the head, tongue moving against the crown, his spit-slick fingers following.

"Fuck, Cas," Dean breathes, fingers flexing against Cas' scalp. "What are you doing to me?"

Cas' eyes flicker up to him and he pulls off, licking his lips. "If you have to ask, I must not be doing it right." He mouths at Dean's shaft, blinks at him in a way that would be innocent if Dean's cock wasn't in his face. "Do you find me...lacking?" Cas asks, his breath blowing across Dean's damp skin.

Dean shudders, fingers running through Cas' hair. "No," he says. "Never."

Cas smirks, hand squeezing gently around him. "Good." And then his mouth returns and Dean's eyes roll back in his head.

Cas works him with his hand and mouth, lips and tongue and just a hint of teeth. Dean groans and tries to thrust against the hand at his hip, never letting go of Cas, never—

The hand around his cock disappears and Cas swallows Dean down, all the way. His throat closes tight around Dean and that's it, that's all Dean can take. He comes with a shout, muscles tensing, eyes squeezed shut. He can feel Cas back off, throat working, and he tries to loosen his fingers from Cas' hair, but it's so hard to let go.

When Dean opens his eyes again, Cas is still bent over him, wiping some of Dean's come from the corner of his mouth, pink tongue flicking out to lick it away. Dean's breath catches, and Cas looks up at him, smiling in a way that makes Dean think all sorts of wonderful, contradictory things, all of them wicked and good and promising. Cas leans back in without a word and licks Dean clean, tongue gentle. Dean shivers, hands moving from Cas' hair to his cheek. Cas' stubble rasps against his fingers, and Dean wants to feel that against his cheek again, wants to roll Cas over and pin him to the bed, taste it with his tongue. He wants to strip Cas naked and touch everywhere, do everything he's only begun imagining and more.

The way the night is going, Cas probably has some ideas of his own tucked up his sleeve. Dean should strip him, just to make sure.

“Cas,” he says, swallowing when his voice comes out rough and thick. He licks his lips and tries again. “Cas, come here.”

Cas does, crawling up Dean’s body without hesitation. He hovers above Dean on hands and knees, taking up Dean’s space, breathing Dean’s air. Dean wouldn’t have him any place else.

“Do you know what I’m thinking now?"

Cas smiles, and Dean’s heart skips. “Yes,” he answers, “I think I do.”
