Cinderella: A BDSM Retelling

Dominas Arabelle and Druscilla Ravyn's talented apprentice, Cinderella, wants to become a Mistress, but the cruel stepsisters thwart her at every turn. When famous rock star Kink-Bottom Prince is seeking a new Mistress from all those in the City, poor Cinderella doesn't think she stands a chance. But a kind Fairy Kink Mother magically appears to help Cinderella win her Prince's collar - and heart.
A 21, 000+ word erotic novella. EXCERPT:"Some Fairy Kink Mothers might let you go just like that, because admittedly you are magnificent as you are. But I didn't win the prestigious honor of Fairy Kink Mother of the Year six years running from doing only the bare minimum. if you'll pardon the pun!" She laughed at her own witticism, but Cinderella was too overwhelmed to say a word."Oh, my stars, I nearly forgot the most important part!" Again she reached into the ridiculously tiny bag and started to pull out golden straps attached to something.
As with the other things, it seemed to start out doll-sized, and then grew to full size bit by bit as she pulled it out. The strangeness of this magic almost made Cinderella dizzy to behold. Now she saw that it was a strap-on harness, with an amazingly life-like member complete with smooth balls attached. It all gleamed as golden as Cinderella's skin did now, who accepted the Fairy's proffered arm as she helped the girl step into the harness.
It seemed to tighten by itself to fit Cinderella perfectly, and Fairy Kink Mother beamed with excitement."This isn't any ordinary strap-on, my dear. Oh, no, no! This is so very special, and if I do say so myself, it may just be my most brilliant creation to date!" Fairy Kink Mother chortled with delight, clapping her hands like a little girl. "It's a brilliant creation, isn't it? Go on, touch it, see for yourself!"
