Licking his lips, Cas flashed him a sleep smirk as his fingers danced and teased over the hunters cock with expert ease.Thumbing at the head he leaned foward, placing a soft kiss on his neck before sliding to the ground, to his knees, breathing over it with warm breathe if only to tease Dean further.
Glancing up at him Cas's smirk widened before he slid foward, lapping at his cock with slow even kitten licks.His goal for the moment clearly to drive the younger hunter mad.
