"I am fond of the slave dances. It is hard for a woman to be more beautiful than when she dances her beauty as a slave before masters. But then a woman can be incredible beautiful in almost all attitudes and postures.... A woman can be very beautiful simply greeting her master, head down, at the door of his chambers, She can be very beautiful in doing so small a thing as pouring his wine, eyes downcast, gracefully, as his slave. Perhaps she is a bit more beautiful, however when she kneels, helplessly before you or lies piteously at your feet supplicating you to satisfy her slave need. Perhaps she is most beautiful when she, collared in your arms, cries out in orgasm, acknowledging you as her master."

More from the books about posture and appearence.

The attitude part is in our opinion at least 90% of one's appearance and posture.

If one's heart is not in it a preceptive Master will know.

Just as the submissive must be aware of thier dominant's attitudes, so too he must be aware of hers.
