He set the remote to age change and positioned himself inconspicuously in an aisle of books about twenty feet from her. As he pretended to peruse the books he aimed the remote at her and shaved off a year with one push of the button.
She shrank a little, maybe an inch, nothing noticeable. She really was high school aged now. A few more pushes of the button and a few more years dropped off leaving her fourteen years old.
She couldn't help but notice the changes now, he thought. Her clothes hung loose on her diminished frame. Her breasts, which had been only B cup sized before, were hardly even visible under her loose sweater. She couldn't be more than 4'8" now. But, there she stood oblivious, still intently paging through her book. Though, she now had to frequently push her glasses back as they repeatedly slid down her smaller girlish nose. She looked like a high school girl who had snuck into a college library wearing her older sister's clothes.
He decided that a more drastic change was in order.
