Hermione Granger was upset, more than upset she was livid, her parents had told her she wasn't allowed to buy a pet, and now while walking down Diagon ally with her best friend Harry Potter she said to him, "I can't believe my parents said no, I'm responsible enough for a pet I manage to take care of you well enough, don't I Harry? " She asked him.
Harry was a rather short boy, almost a full head shorter than her and looked rather worried at where Hermione's thoughts where headed, as she looked down at him the beginnings of a plan started to form in her mind.
Meanwhile Harry not wanting to upset her had responded, "of course you do Hermione, and I'm sure you would take excellent care of a pet, why I bet they would be lining up in the streets begging you to be there master if they could." He said.
"You really believe that Harry?" She asked, sounding rather hopeful. "Would you want be my pet if you could?"
"Well, umm sure I would, but I don't think that's allowed Hermione there's probably a rule against it," he said.
"Oh honestly Harry," she said looking rather excited, "you really need to read Hogwarts a history, that can be on of the first things we do together. Oh it's going to be so grand having my own little pet to take care of."
"What do you mean?" He asked "how are you going to get a pet?"
"In Hogwarts a history it says that students may willing submit themselves to another as there pet," Hermione explained, "you do want to be my pet don't you Harry?"
"Of course I do," Harry started, however a bright light suddenly glowed around him.
"Don't worry, that was just your magic accepting your new place as my pet." Hermione explained while softly petting his hair. "Now we just need to wait while it makes the appropriate changes to your body, and then I'll be your new master."
"Wait, what changes?" Harry asked, looking rather panicked.
What change do you want?
