It was quite endearing how much Luna trusted Merlin with aspects of her real life, in a way that she wouldn't with any other client (he was quite reasonably sure.) He gave her a slightly smug smile, feeling superior to all those faceless people. "Complete submission, my my. Ambitious," he said, rolling his hips lightly against hers, just to feel the warmth of where they were joined. He was prepared to let it go, buuuuuut he wasn't very good at that really.
"But really, my dear, that is an awful lot of work for one person. Add in the travel time, and you aren't getting a moment to yourself, being buffeted about hither and yon. I just worry about you." He cupped her cheek with his palm, paternalistic in his affection.
