Head to the Back Room

Still on her knees behind the counter, Kirsty slowly crawls away, keeping her skirt in one hand. As far as she knows she's completely covered, but with you hovering there invisible you're treated to a great view of her arse and stockings as she crawls.

Making it to the end of the counter, Kirsty pokes her head out once more, looking at the security guards still sat there drinking their coffee. The door to the backroom is only about five paces away, but there's no cover between the door and the guards, meaning she'll have to make a run for it.
