It was another day at the bunker, and Dean had just woken up after closing a case the previous night. He was tired and drained but the strong scent of coffee pulled him out of bed and towards the table at which he had breakfast every morning. He dragged his limp body out of bed, wearing nothing but boxers and sweatpants. Dean tugged one leg after the other, until he saw Cas, pouring a mug of coffee and placing it gently on the table. Cas looked up, Dean saw his blue eyes shine as a smile shot across his face. Cas was wearing some jeans, a black t-shirt and of course, his trench coat over the top.
"Morning." Dean muttered with his eyes still semi-closed.
"Good Morning" Cas said back cheerfully "I knew you'd be tired so I made you coffee"
Dean smiled, for the first time in a while. He slowly walked over to the table and shot a grin at Cas, holding out a chair for him. Dean sat down and Castiel pushed the chair in. After a rough night, being with Cas again filled Dean with a happiness that he hadn't felt before in his life.
Dean lifted the mug to his mouth as Castiel watched eagerly waiting for Dean's reaction. He took a sip and swallowed. He beamed at Cas, which caused Cas to grin back at him. Cas took a minute, to look into Dean's brown eyes. For the first time in a long time he saw genuine happiness in the dark eyes.
"Cas! Castiel!" Dean said as he clicked his fingers in front of the angel.
Cas jumped out of his trance and looked down at his feet blushing. He felt embarrassed and he could feel himself being judged by his best friend. He felt a gentle, warm touch on his cheek. He put his hand to it and felt Dean's. He rubbed it soothingly and looked up to see Dean's bright smile.
Suddenly, the door flew open, it was Sam, back from his morning jog. He looked down to see his brother caressing Castiel's cheek and stared for a second. Dean looked down nervously, suddenly letting go of Cas and going back to drinking his coffee.
"Dean?" Sammy asked "Are you drunk?"
Improvising, Dean thought it would be best if Sam just went with that assumption so he slurred the words "Noooo, I only had 4 glasses of Ja-" He then pretended to pass out in the hopes that Sam would fall for it. Sammy came down the stairs to flick Dean's ear and walked off. Dean then looked back up at Cas, who was oblivious to the awkwardness Dean had just experienced and they smiled at each other, the way two friends smile after they've just pulled off lying to their parents.
Later that day, Dean was laying on his bed, headphones blocking out the world. He was listening to a Black Sabbath album, thinking about Cas; nothing sexual, just spending time with him. He was thinking about how Castiel's eyes were a bright blue when he was happy and a dark, grey-blue when he was feeling sad. Thinking about Cas being sad, made Dean feel despair, so I focused on the music, but he couldn't get that angel out of his head.
Dean didn't see Cas for the rest of the day since he had to do some work with the Angel Tablet. Dean couldn't stop thinking about him: his trench coat, his smile, his laugh and his messy hair. Dean loved it, he loved the way it weaved into itself but still looked nice enough for bath towel. This thought made Dean grined to himself. He stayed listening to music and thinking about the Angel, the angel who had changed his life. He fell asleep with Cas in his mind.
