Mistress, first off I agree with Worm.

About the subject I have experienced, oh how can I put it, "alleged" chastity via phone or text. With one Mistress who lived on the West Coast and I would see two, three times a year we would talk about session planning or a day or two after a meeting; her travels; or her marketing / vanilla business I might help her with. She had an almost announcer-like voice and very seductive. If I was too quiet at some point, or made a suggestive reference, the Mistress came out in full force: "Stop that right now!" or, "Text me tomorrow for further instructions." Sometimes she would say, "Well, I have an appointment and must go." I would sometimes say, "Mistress I have one more question..." and she would cut me off and say, "You have my permission. Text me immediately after you are done."

She was controlling my pleasure across country. She knew it, I knew it, and I was possibly in the deepest subspace of my life. All without equipment, just imagination.
