Having served a Mistress in RL and been edged sometimes for hours in front of her friends I would say the longer it goes on for the harder the end result is at least that is my experience yes it definitely changed me for now I crave itIs this an appealing concept to many? I'm not speaking of the kind of tease that goes on for a few minutes before the subject is allowed grateful release.
I'm referring to the kind of tease that escalates over hours, perhaps even days, before what can only be described as "life-changing" release is granted, and the subject is alternately exhausted, exhilarated, vulnerable and ravenous, as the experience has introduced them to a side of themselves they had no idea was so starved for that kind of unique attention.
I believe for those with slightly sub tendencies, the notion of offering the right person that kind of power is frightening yet very simple and freeing. It can lead to a lovely friendship if the chemistry is favorable.
