I see two big problems with this. One, tattoos are permanent. What if, hypothetically, something were to happen between you two? Something like splitting up and seeing other people, or even reversing roles at some point? That tattoo would be a bitch to explain, and it would be incredibly annoying to live with.

Second, a tattoo would be a permanent punishment for a most likely small, temporary thing. I would highly recommend using pen or marker instead of leaving a permanent reminder of a small mistake. Just as an example, if I ate without permission, Master wouldn't insist on giving me a tattoo or branding me. He would find a form of punishment that fit the act. In my opinion, it's almost cruel to do something that cannot be reversed as punishment for something that can be corrected through other, less permanent means.
