A Mother's Worry (My Story) shouldn't be in PDF anywhere but Smashwords, but it is free on Lit (Literotica) and SOL (StoriesOnline) with the stories StoriesOnline version having Jenna's original age of...well, her original age, so the story makes a little more sense when it comes to the mother's 'worry.'
Since it's free free online, copy it page by page, put in a word doc and use calibre to make your own PDF, I only ask you don't spread it around online. I think at SOL they give you the option of downloading each chapter individually.
