"Hmm", Dean hummed as he picked up the guitar. The glossy finish glittered as sun light struck it. He settles in a chair, the curve of the guitar fits around his knee perfectly. Strumming the strings, a tune begun to form. Dean's mind formed words and begun molding them into lyrics. But then his one true love's name flickered around his head causing the lyrics to form into a love song. "I don't want Sammy to know this is for Cas if he wonders in... Cas is an angel. What's a chick's name close to angel that's not, well, angel..? Angeles!"
Dean never noticed the angel in the corner. The grace filled being hid himself so that the hunter wouldn't get spooked and stop mid song. Castiel listens as Dean's lips formed words. The angel was in awe at the way he strung the words out, creating the song, and the way his voice was smooth and velvet like. So beautiful, Castiel thought. The song was coming to an end, Castiel could tell, but he lusted for more.
As Dean finishes the song the angel came out of hiding. The hunter didn't notice him until a gruff voice whispered his name. "Dean. That-that was beautiful...",Castiel was still in shock at the light and lovely words that came out of the rough hunter. "Oh God, Cas! What the hell?! Don't sneak up on me like that", Dean exclaimed. "My apologies, Dean", Castiel apologized, "But may I ask, what was the song about?" Dean shied away a little, "You."
