Amazing series, loving the idea of being mistaken as an object. Unaware theme is really hot for me and it's the best. Looking forward to the next chapters you add in.

As for a suggestion, maybe being mistaken as a bottle of lotion or tube of cream? Was hoping for feet, like she thinks he's precum/cum is lotion that she forces it out of him with some difficulty, the "lotion" isn't coming out easily, so she plays with it and try different methods to get more out, including using her toes on the nozzle a.k.a. his dick.

I somewhat enjoy the concept but the writing style is pretty awful and a complete chore to get through. 

Fantastic story plot.  I really like the concept, it's full of limitless potential.

Being Hazel's nipple piercing, now that's pretty hot.

One thing I am curious about, will Jake come to realize the curse he read in the book?  Perhaps by the librarian finding the open book he read and stating aloud that someone might have read a curse that turns them into objects unknown by the person in search of such an object; perhaps even realizing herself an object she was searching for suddenly appeared and has been using might in fact be the person who innocently and accidentally read the curse.

I agree with the objects Odysseus mentioned, and would like to add a woman's panty, her hankerchief to blow her nose, Q-tip for ear and nose cleaning, cozy slipper(s), lollipop, bubblegum, lipstick, toothbrush, pet dog / cat, and of course her dildo / vibrator.

My only complaint is your grammatical presentation, especially the long, run on sentences; and confusing multiple subject matter covered in a single sentence.  Would be great if you could clean up your sentence structure.  Otherwise, top notch.
