Maid Charlotte and the Other Maid

I have lots of sexy feminine clothes to wear but was disappointed when my mistress wanted me to be dressed as her maid when we went out. Things got better though, when she dressed as a dominant latex mistress with metal-heeled boots and I was her sexy sissy maid. The apartment we went to was a mess and my mistress informed the blond maid that lived there with her master that she had the authority to discipline her. But why did her master not meet us when we got there? And what was in the pvc bag my mistress brought with her?
