Permenant marks

I was asked a while ago by a sub that if we continued along long enough would I put permenant marks on her. I would not answer her , I felt I would be pestered to do so by her at every chance she could bring it up . Was she trying to gain re-assurance that she was mine , or liked body modificatioon or did she tryuly want to show the world she was owned. I am still thinking on that .
A few months ago another asked that question but she asked me what type of marks I would use and would it be a one time thing or a graduated journey. This sub showed thought in her questions so I answered like this.

At first a collar would be provided one she would be required to wear no matter where she went never taking it off without my permission, when I saw she could do this without exception then I would move to chains. I would pierce her nipples and run a chain through the rings. again she would have to show that she would wear it at all times including anytime she had to remove her clothing in front of another. Then her vaginal lips would have rings placed i them and the chains would continue from nipples to lips.
this would be the first part of the marking and would take place over the first five years of our relation. Any regression such as showimng me she had slipped in her training would result in the removal of the last step such as removal of the rings in her lips and if the poor behavior continues she would loose the nipple rings . They would not be replace until she proved herself and yes the flesh would have to had healed before she woud be allowed to have the piercings done again.

Once this level was maintained I would progress to a tatoo first one that would be seen by most as it would be across the top of her butt cheeks so if the her top moved or her pants were low on her back it would be exposed, it woul d progress from there to parts of her back and arms.. Then a navel ring to allow the chains to be gathered.

Last would be a branding that would occur only many years into the journey when I felt she had become the ideal submissive a slave. The branding would be of a private matter shared only with close friends.

I would not say to anyone , my submissive or others that this is not what must be I would be happy to have a slave with no marks no chains no brandings as I feel a good sub/slave proves that she is owned every day she kneels at my feet and gives of herself to me because she wishes to and not because she feels she has to. I would only place these marks should the slave wish them and I would use each level as a reward to her for her achievements. Just my thoughts on the matter
