You quickly realize that the best plan is to go to the back offices, where all the staff librarians work during the day. You probably won't know anyone back there, but finding a student, especially someone you can trust, could take all day. Finding an adult would be better.
On the walk over past rows and rows of books, you see your first giant, a male student walking by. You don't recognize the face, but his giant strides cover what looks like miles in mere seconds. Fortunately, you have the common sense to duck into a row of books and hide behind a large text on the bottom shelf. You keep kicking yourself for not being closer to a hiding place, but if the giant noticed you, he didn't show any signs of it. Thanking your good luck, you walk a lot more cautiously, staying closer to the walls.
As a result of your more reserved approach, you don't reach the door to the library offices for about an hour. You had worried on the walk over that you might not be able to sneak under the door, but there's plenty of room and you enter easily. The office area, a hallway with open doors off on each side, feels a little more active than the stacks, but you still don't see anyone.
Hanging close to the walls, terrified of what you would do if someone walked by, you reach the first office. High above you, the name on the door says "MARY LYNN MORRIS" and you take a peek around the corner to see who's in the office. You're in luck: it's a woman in her late 30s or early 40s, typing on her computer with a serious look on her face. She's blonde and pretty, and she seems to have quite a nice chest too. You're not sure what factors you should be considering as you look for a random stranger to restore your size, but you figure an attractive woman is as good a choice as any other. You walk into her office.
Your first step is to walk towards her desk, where she can't see you. You're not sure what would be the best approach to introduce yourself to her, but it's probably a good idea to get as close as possible before she notices so she can tell you're a person, not a mouse or something. So you walk up to her desk and continue under, until you stop right by her feet.
At this point you can see most of her body, up to her stomach, and you soak in your first view of a giantess. Everything about her is absolutely enormous, which you could have guessed, but it still strikes you as amazing, seeing every part of her body in gigantic form. Her shoes are several times taller than you are, and you think about how her feet are probably the height of some one-story buildings as you watch her legs, crossed at the ankles, dangling her shoes around as if they were nothing. Mary Lynn has complemented her black shoes with black pants and a black button-down blouse. From what you can see of her, she's really quite sexy. You realize that any motion of her shoes, though, could completely kill you in an instant. She's as powerful as she is sexy. You find yourself backing away involuntarily.
Eventually you calm yourself to the point where you want to make contact, which of course was the point of all this, but you're not sure what to do. She's leaning forward in her chair a little, and now her head is almost directly above you. You wait for a moment, expecting her to look down and see you, but you're surprised and disappointed to discover that she seems to be intent on her work. Realizing that you'll have to notify her somehow, you shout, "Hello!" in the hopes that she'll be able to hear. Better that than banging on her shoe, right?
She loses her concentration with a start. Contrary to the slow recognition you had expected, she looks down suddenly, sees you instantly, and leans back into her chair in shock. Her jaw has dropped, and her eyes never leave you. She stays like that for several seconds, and you stare back at her. Suddenly her arm shoots out at you, and before you know what's happening you're in her giant fist being carried upward. You only have time to notice that your stomach isn't possibly prepared to travel at this speed before she shoves you somewhere and pulls her hand away. As the light goes out in fits and spurts, you feel soft, bouncy flesh pressing down on you and a wide cloth below you. You realize Mary Lynn has just stuffed you in her bra. As it turns out, you can barely move, though you suspect you could climb out if you needed to.
