Hello slv4u. That is referred to as virtual chastity, which some subs and Mistresses actually find more satisfying. And that is real chastity, in my opinion, because it is based on the honor system, which means you really are doing it to comply with her wishes.

Many find it comforting to have this "link" or connection with someone. It helps them feel a part of something secret and that little bit of contact, especially during stressful times, can be a great solace.
