Some slaves may get down on the idea they are just ‘passive’ when it comes to their service but, in actuality, a slave is more active than any time of significant other.
A slave is an extension of his or her Goddess or Mistress; so, therefore, are expected to perform more readily and more intimately than others. Using a slave is simply a Goddess pleasuring herself with one of the ‘tools’ at her disposal; she has no reason to be hesitant with her slave and will be much more willing to experiment and push a slave’s limits.
