Often times a slave is put in charge over other slaves.
When I was first introduced to bondage it was under the tutalage of a "First Girl" I was in both theory and practice her slave as much as her Owner's.
So if one wishes to submit to another why not.
Ownership however encompassess somthing far more serious.
Ownership for us is beyound merely being a dominant or a Master or having a submissive kneel before you.
It asumes a matle of great responsibility for the life of another human being in total and requires a much higher level of devotion.
