He lets his head fall back listlessly and holds his breath to allow his body a chance to adjust and unwind under the gentle but enthusiastic stimulation of his lover’s mouth. The smoke folds into every nerve and muscle, relaxing his posture and mind alike long after he exhales.
Castiel takes his time easing his lips down the length of Dean’s member, humming at the thickness and savoring the pulsing weight against his tongue. He bobs slowly, salivating generously and toying with the dense vein along the underside of Dean’s cock on every descent. A hand in his air is what ultimately pulls him from his task.
He looks up at Dean through half lidded eyes, the vibrant blue of his eyes just halos around his blown out pupils. Cas meets Dean’s gaze first before gradually straying to lock on to the joint his fearless leader is holding out to him.
Castiel accepts it without hesitation but pauses when Dean pulls it away just out of reach. He blinks curiously but catches on quickly as Dean lowers his hand again, placing the end of the joint between Cas’ lips and eyeing him throughout his steady inhale with a powerful yet affectionate stare.
Dean plucks the blunt from Castiel’s mouth and places it back in his own, lips twitching upwards at the corner when Cas exhales against his dick. He notices the former angel’s eyelids getting heavy and smiles when Cas nuzzles up against his thigh.
Smiling, he hunches over and effortlessly scoops the other man up and off the floor by his armpits. Cas straddles his lap and slumps against his bare chest with a quiet hum, settling in Dean’s warm embrace.
"Will you follow me?" Dean’s voice vibrates him to the very core, so deep and penetrative.
Before Castiel can answer, Dean is carding a hand through his hair, easing his head back, and shotgunning the thick smoke right into his mouth. The sensation has Cas parting his lips obediently and inhaling deep before shakily closing the distance between them and claiming Dean’s lips in a desperate, heated kiss.
He whispers against his mouth, “Always.”
