He wondered when she would tell him to shut up. Any moment now Meg would put her foot down. He had already called her beautiful several times. The opposite request made him chuckle softly. One arm propped up his head so that Castiel could look down on Meg's face and the other moved against her cheek. His thumb stroked the dark smokey wisps buried far below her skin.
"She walks in beauty, like the night Of cloudless climes and starry skies; And all that's best of dark and bright Meet in her aspect and her eyes: Thus mellowed to that tender light Which heaven to gaudy day denies."
Before she could scold him for the poetry he leaned down and kissed. A light kiss meant to keep her from immediately speaking then he was again looking down at her, "You are beautiful." His thumb continued to trace patterns of her cheek. For a moment he watched her absorb those words and then he leaned back down for a deeper kiss.
