My girlfriend and I are new to S&M and we want to try to be less vanilla. She is the submissive in the relationship and I've decided to find a way to discreetly brand her as my slave. Discreetly because like I said we are still vanilla and she has to hide this from her friends and family. I decided on an anklet. I want to engrave it since the engraving will be small and unnoticeable. There's two lines and 8 characters per line available. Any suggestions of what to put to make it discreet but clear? i.e. property of, loving slave, etc. etc. Thanks in advance!
