That's okay. Dean can't even begin to decipher what he's feeling. Maybe if he'd ever had a healthy relationship in his life, but he hasn't so he can't.

Dean tries to say something about needing to prep in case the Leviathan shows up, but he can't get a word in edgewise. Not that he's complaining. Or trying to stop Cas. No, he's a little busy trying to get Cas' shirt off so he can manhandle him, stroking his hands down Cas' spine and over his hips. Dean's jeans are just a little big on Cas. Makes it easing to tuck his fingers beneath the waistband.
