The coy smile on his face and his gentle air might be betrayed by his objective, but not entirely. He brings his free hand back up to curl back and gently touch at Crowley's hair, while the other keeps intertwined with the demon's on his chest. The stuttering doesn't pass him by, in fact he finds it quite endearing. There's a rather lovely feeling in being able to catch the demon by surprise sometimes.

He turns his head to place a gentle kiss on Crowley's cheekbone. "I do." He murmurs sweetly against his cheek, a fair easier answer; he's feeling Crowley's already, which he shifts against again, just a gentle tease.
