A smile dawned on Merlin's lips slow and sweet, just like the song. Dean had a really nice voice and it made shivers run down along his spine to listen to him. Music was like magic to him, mysterious how some people had it and some just didn't. He was in the latter category.

His hands rose to Dean's jaw and cupped it to keep him right there to give him a few more kisses. "I'd listen to you all day long," he murmured and nipped on Dean's bottom lip.

"Sing some more," he murmured while flipping them over again, raining kisses on Dean's chest and stomach.
