He can't help the twitch of a smile at the positive feedback. Meg hadn't complained, and Crowley had been enthused during their last encounter, so technically he didn't need the verbal praise, but... He's relieved and pleased to hear it all the same. He can taste the salt of Crowley's skin against his lip, and he closes the tip of his thumb in his mouth briefly, releasing it with a scrape of his teeth.

"Thank you. You're enjoyable as well." Understatement. Castiel doesn't have much of anything to compare Crowley to, but he's definitely been affected by his kissing.

He's also not quite sure why being forcefully undressed should be so arousing, and yet it is. He pulls off his shirt and jacket together and lets them fall to the floor, far less interested in the fate of his clothes than Crowley might be of his own. Once his hands are free, he sets them on Crowley's waist, and they take a second before they settle fully against his skin. Dipping his head, he kisses Crowley again, and he tugs him closer, eager for more contact, for more... anything.
