Follower @kuanyu3 asked in a comment for some examples of mantras that a Dom might give to their sub during, for example, maintenance. Here are a few off the top of my head:
“This girl’s peace is at her Master/Sir/Daddy’s feet.”
“This girl is good/beautiful/amazing.”
“This girl is her Master/Sir/Daddy’s most cherished possession.”
“This girl is her Master/Sir/Daddy’s greedy little fuck-toy.”
You get the idea.
