Humming softly under his breathe, Cas rescued his beer once the hunter returned it, tracking his movements with a faint tilt of his head.His grin faded just slightly when Dean remained quiet, considering he knew the hunters mood first hand.Could tell exactly how far to push and poke his buttons just by the others body lanauge alone.The mood swings had been on of the first thing the stoner had learned, he'd had to if he was going to risk going through life bullet wound free.
Hissing slightly at the unexpected punch, he winced slightly but other then a suprised squack of "Fuck!", merly reached up to rub the irritated skin softly.Rather then fight back however, Cas licked his lips as he stared at the hunter eyes becoming hooded, almost as if encouraging him to do it again.
