I have read your posting and the details of what you are looking for.
I am an experienced Master who has been in and around the D/s scene for 20 years or so. I am sincere and tolerant. Safe but strict. Looking for a long term arrangement.
Unlike others who promote themselves as being Masters I actually operate within the confines of reality. Building a trust based relationship with a sub and in return for obedience and control work to enable a sub to achieve what they are seeking.
Limits are respected as are the subs responsibilities surrounding work, education, family and other relationships.
If this is of interest to you then contact me and we will discuss things further.
