I'm thinking of a conversation between a Master and a slave -- of course, I can't remember which book or which couple -- in which the slave was told that her duty was not to respect herself, nor should she wish to be respected. Rather, she should be a completely passionate, sexual, submissive creature, one who strove always to perfect her own slavery. And then I think it went into this bit about how a slave is her own best trainer because she would always seek to be what that Master wanted; HIS perfect slave.
