Mary was well known by all the law students at the University. While everyone would say it was because she was always willing and able to help find any case or book that anyone could ever need but in truth it was that she was by far the most attractive woman on campus. At just a little over 5 foot her petite form was a perfect hourglass with perky 8F breasts which were then balanced by the most perfect tight little bubble butt anywhere on campus, catching the stares of student and staff alike. Although her form was that of utter perfection she always made a point of trying to dress in a demure and respectable manner while she was at work so as to avoid silly comments from her colleagues (not to mention some of the jealous female students) but there was only so much that could be done to hide her beauty. Her long jet black hair which would normally wave its way down to the small of her back was kept pulled back into a tight bun, and her emerald green almond shaped eyes gazed out through cliché librarian-esque glasses. She always wore a plain white cotton blouse with only the top button undone, with a simple black waistcoat overtop that served to subtly highlight her slim waist and the contrast between that which was above and below and then a plain black knee length skirt. Plain, simple and respectable attire for a librarian. However, when she was working on her own doing the evening till close shift she would wear something a little more fitting to her own tastes, not to mention the tastes of the students. So the blouse was undone further down letting her cleavage push its way into view, the black knee length skirt was replaced with a tight fitting (only just arse length) mini skirt and the back stockings were changed to thigh high fine fishnets with a black lace garter belt with a matching black thong over top. Quite simply she changed from trying somewhat in vain to hide her assets from her colleagues to almost flaunting them to those few dedicated students there late working hard. She knew that some people checked her out but she had always been quite reserved about approaching anyone due to the fear of what would happen if people found out what she did. That didn’t stop her from thinking about what she would do if she did…
