Sorra was bothered by the fact that Master Callembad never asked her to do any interesting tasks. As his wizard's apprentice she thought that by now she might have learned to do something interesting at least. Instead she was always cleaning the many rooms and labs in his large and lonely magical fortress and running his menial errands such as picking up groceries or ingredients. She couldn't deny that Master Callembad was a spectacularly skilled wizard. She had seen his work far too many times to doubt that.
On top of all of the boring work that he gave to Sorra, Master Callembad was an unparalleled pervert! He made Sorra dress in a skimpy little skirt which barely did anything to hide her rear, especially when she was bent over to clean as she so often was. She also was made to wear a tight, white crop-top of a blouse which she had to stretch over her large breasts to be able to button every morning.
Truth be told, Sorra didn't actually mind the slutty little uniform, in fact she thought it was fun and freeing, and did little to limit her movements as she worked throughout the day. What she did mind was Master Callembad's constant staring, and "accidental" groping.
Master Callembad called Sorra into his study early one morning to inform her that he would be leaving the fortress for several weeks to locate an ancient tomb of some great, dead, wizard or something. Sorra didn't pay too much attention to the details but did hear when Master said "While I am gone, you are the dust the entirety of my library. I want every tome to shine like it was just written yesterday understand?" he continued, "But under no circumstance are you to read anything within the restricted section of the library, hear me? Do NOT read any restricted books!"
Sorra nodded with a "Yes Master". Before long Master Callembad had left for his expedition leaving Sorra all alone within the large fortress once again. She didn't mind this at all and figured she would get a head-start on her dusting, so she head to the library promptly.
She entered the room with its massive shelves of dark, dangerous, magical tomes and began dusting right away. Before long she found herself in the restricted section where the layers of dust seemed to be the thickest. She thought loudly within her own head, "Stupid Master! I hate that its always work with him. He never lets me practice magic, but if I am going to be a great wizard like him some day I should be reading, and mastering my own knowledge!".
It did not take long at all for her to abandon her duties. She started looking through the half-dusted tomes in the restricted section. One large book stood out to her in particular. The spine of the book was bound with thin, vine-like braids of green and red. The title, in gold leaf, stood out to her plainly: "The Tentaculum Imperia". She just knew that she had to read it.
Sorra ran from the library to her bedroom with the new book and jumped onto her bed. She imagined all of the great things that could be contained within such an interesting looking book. She held the front cover heavily and pulled the book open. Magical light spilled out of its pages and a long, slim, slick tentacle appeared from the pages and immediately reached for the unsuspecting Sorra.
