Waiting for Sam and Jack to come back from their usual pit stop, Dean waits in the driver seat as Cas sits in the back. As the cold gets chillier, Dean hugs himself, trying to get warm. Looking out to see where Sam and Jack are, he sees Jack in line waiting for port-a-potty. Sam is still choosing road food from the snack machine.
Dean chuckles as he points to Sam, “probably trying to find something healthy. He won't find that in a machine.”
Cas gives him a lopsided smile as he continues to take in his surroundings.
Noticing Dean rub his arms, Cas taps the back of his seat, grabbing his attention, “Are you cold, Dean?”
“You're rubbing your arms; you want something warm?”
“And what do you have back there? A heater?”
Cas lets out a soft chuckle. When Dean feels the Impala rock a little, he looks behind him seeing Castiel take off his trenchcoat. He's never seen his angel without his trenchcoat off before. Looking at him, he notices Cas is wearing his black overshirt along with a red tie that Jack got him for his birthday. Handing his coat to Dean, Dean waves him off, “Nonono, you don't have to do that.”
Wiggling it for him to take it, he stretches his arm out a bit more, “please, Dean, take it. It'll make you warm.”
“It's not even that cold, Cas.”
Pulling back his trenchcoat, he bundles it in his arms, “Then step out and see.”
“I'm not gonna go outside, it's cold.”
Sighing, Cas scrubs a hand down his face, “unbelievable.”
“I'll show you ridiculous.”
As Dean gets out of the car, he stands around for a little while, noticing Jack is finally using the bathroom and Sam is opening up a grocery bag. Leaning into the open window, he smirks at Cas, as he stretches his arms out, “See? Not that cold, Cas.”
Cas gives him a tiny smile as he hands his trenchcoat to Dean again, “My offer still stands.”
Looking at Sam, he sees him still contemplating whether or not to get more food. Opening the passenger door, Dean lays a knee on the bench seat as he takes the coat from Cas’ outstretched hand.
As Dean puts on his coat, he inches his way in more, almost walking on his knees to put it on.
“Yeah? Looks good on me?”
“Very” Cas answers breathlessly.
Smoothing it out, Dean smiles at Cas, “hmm…kinda like it actually.” He lifts up a lapel to sniff it, “smells like you.”
“Of course it does, it's mine.”
Sitting up to make room for Dean, Cas gets a better look at him, “You look very attractive in my clothes, Dean.”
Dean slowly sits in the backseat with Cas, scooting closer to him.
“I uh, find you attractive too, Cas.”
As he inches closer, Dean finally takes that leap he's been trying to do for years now. He softly kisses Cas as his angel moans in his mouth.
As he carefully caresses Dean's face, he doesn't break their kiss as he maneuvers himself to lie down. Feeling Dean's smile between kisses, Cas thrusts his hips slightly as Dean does the same.
Dean hits his head hard on the roof when he hears a loud knock on Baby's hood.
“Seriously, guys? Come on, Jack is gonna be scarred for life.”
