Mistress Severin's slave is on his knees in front of her but doesn't realize just yet that today he will be experiencing something he has not experienced before.  Mistress has laid out several new pieces of fetish gear as today he is going to be transformed from her average slave to her puppy slave! She plans to make  him a full on puppy with a collar and leash, a puppy mask, and even puppy paws!  She doesn't want her new pup to start humping things and certainly not other people, without her permission, so she decides to put his little puppy penis in chastity, just to make sure he behaves.  Once she has her new puppy slave in all his gear she realizes something very important is missing...a puppy tail!  She tells him that she will go shopping for a tail, so next time she sees him he will be a proper pup!  She informs him he will be treated and act fully as her puppy, not a human, and if he behaves she will give him pets, take him for walks, and even make him lap up her pee from a doggy bowl!
