D is for Dean
Castiel watched as Dean slept. He was spread eagle on his stomach. He had pretty much pushed Castiel out of bed. He didn't mind as he had been having trouble sleeping anyway. This gave him a chance to think about his new relationship with Dean.
Ever since Castiel had fallen, the two had begun dating. Castiel had been in love with Dean for so long, but it had taken Dean almost losing Castiel to admit his feelings. When he had fallen, Dean had thought he had died. Castiel had awoken to Dean's confession. Ever since, the two had been learning how to express their feelings, with Sam mediating some of their arguments.
Castiel had moved to a chair in the room, so as not to disturb Dean. He took to watching the other man sleep. It was something he would never tire of. Dean always looked so peaceful when he slept. Any other time Dean had a hardened look in his eyes and was tense, less so when Castiel was around, but still stiff. It almost seemed like Dean didn't have a care in the world right now.
If Castiel could stay in this moment forever, he would be content. Then again, he wouldn't get to see Dean smile anymore, or be able to get lost in his green eyes. On second thought, Castiel liked Dean more when he was awake.
"Cas?"
Castiel returned his gaze to Dean's face. He saw the Hunter looking at him quizzically.
"Come back to bed."
"Sorry," Castiel replied. He stood and climbed back up onto the bed. "I could not sleep, and I did not want to disturb you."
"S'okay, but I like you better over here," Dean replied sluggishly, pulling the angel close. He pressed his face into Castiel's neck. "S'better." He mumbled.
Castiel smiled as he allowed the hunter to hold him. He could definitely never tire of this.
