"Hey Cas."
To his credit, Castiel doesn't even flinch when Dean comes up behind him and wraps his arms around his waist, burrowing his face into his neck. Dean can be pretty stealthy when he wants, but it's something Castiel is used to now.
"Hello Dean." He fights back a dopey smile as he leans back slightly against Dean's chest. The younger man's like a walking, talking hot water bottle, and though he's never been one for cuddling; with his soul mate? Castiel supposes he can make an exception.
"Why y'up?" Dean mumbles sleepily, his breath ticklish against Castiel's neck as he speaks.
"Couldn't sleep." The raven-haired man shrugs lightly. "Go back to bed Dean."
"M'up now." Dean shakes his head, peeling himself away from Castiel and opening the fridge. He's practically become a permanent resident at Castiel's apartment now, sleeping over more often than Meg ever has. "M'hungry."
"It's three o'clock in the morning Dean." The older man chuckles softly and rolls his eyes. "And you have work tomorrow. Go back to bed."
"But Caaas!" Dean whines, pouting like a petulant child. "I wan' pancakes!"
"Dean Winchester." Castiel schools his expression to a stern frown. "Go. To. Bed. Now."
"Love it when you get bossy." Dean closes his eyes briefly, smirking, before he suddenly grabs Castiel's hand and drags him back to their bedroom.
"You are ridiculous." Castiel rolls his eyes again as he is gently pushed down onto the bed with his soul mate spooning him from behind.
"You love it." Deam retorts, and Castiel can feel him smiling against his neck.
"I do, now goodnight Dean." Castiel admits, huffing a laugh as he snuggles down and closes his eyes. He sighs contentedly when Dean brushes the lightest of kisses against his neck, before sleep overcomes them both.
