A little more daring

You follow Emma as she walks to the front of the library, watching as she's very careful not to come out from behind the trolley, unaware that you can see her every movement, and feel the thoughts of excitement coming from her.

Looking out the window you see the occasional person walking down the street, but not many, and none of them are paying attention to the library windows, but that doesn't seem to lower Emma's nervousness.

Deciding it's time to up the anti you wait for her to move the cart again, this time adding some of your own power to its movement. The cart sails away, momentarily leaving Emma stood in the window, her pants and stockings on display.
