Recently I was vetting a new cunt/slave and a question came up on how long I would want to keep her. Apparently in one of her previous dynamics she was on a month to month "rental". It was an interesting idea, each month they would discuss her shortcomings, achievements, and whether he wanted to keep her for another month.
In my brain, Ownership is a lifetime commitment. Of course I have released girls in the past, for one reason or another. It never felt right to release them, that it felt like a failure for allowing them to roam free once again.
I am adding this to my vetting process from now on. If they wish to be owned by me then it will be a lifetime Ownership. If I no longer want to keep her then I will find another Owner to take over Ownership.
