Dean arrived one day to the bunker completely tired, after killing three vampires and almost been bitten by one of them.
Limping and hungry.
Sore and bruised.
As he entered through the bunker's door, the first thing he did was to search for Castiel and followed his voice from the library where he was talking to Sam.
He entered the room while they were still talking, and Sam told him:
- Hey, Are you alright?
Dean just stood there for a moment looking directly to Castiel, and then he turned to Sam and he asked him:
- I’m awesome.
Did you finish your conversation?
- Yeah… we were just…
Sam hasn’t even ended to pronounce the last word, and Dean told him:
- Good.
And then he went straight to Cas and kissed him.
First roughly holding his nape with one hand and with the other hand holding Cas's lower jaw against his face while trying to caress it awkwardly. And then, the violent kiss slowly became sweet and tender because the angel gently put his hand on Dean’s head and started to caress his hair.
They stayed a little bit longer like this. Dean started to open his eyes while continuing kissing Castiel softly, tenderly and then as he separated away slowly from his lips he looked at him and told him:
- I needed to feel this with you again. I need this as a reminder of why I’m still doing what I do every day, and why I keep fighting for my life so I can return to this.
Then, he turned to Sam that was there still as a stone watching them, and swallowing heavily.
- I don’t care if tonight another apocalypse is coming or a pack of werewolves tries to enter the bunker. I’m only will be able to take any other case or whatever until tomorrow at noon.
Dean started to walk and told Cas while leaving the library:
- You better be following me.
And then, as they leave the library towards Dean´s bedroom.
Sam could heard Dean saying from the distance:
- And you better wear your headphones all night.
When they were at Dean’s bedroom, they sat together on his bed and start the kissing again. This time with little and soft kisses on Cas lips, on Dean’s neck, on Cas forehead and more kisses on the lips.
Dean tried to remove the trench coat out off Cas, and with this motion he end up sliding onto his lap, so he took this as an opportunity for him to try gently and carefully to undone Castiel’s trousers. And while he was working the zipper, touching him and kissing searching for his dick, he just fell asleep on Castiel’s lap.
So Cas just leaved him there, to rest on his lap while arranging his head to a more comfortable position for Dean.
And while Dean started to snore with a half open mouth, Castiel stroked Dean’s hair and stay there watching his hunter sleeping on his lap.
