The fire alarm goes off!

As Lizzie is writing down measurements and thinking of what her conclusions will be, the halls of the school are filled with the loud, blaring horns signifying a fire drill. Lizzie and the rest of the class are told to leave the room in an orderly fashion and gather at the appropriate spot on the outdoor field. As she made her way outside, she was surprised by the water falling from the sky. It had been sunny when she arrived earlier, but now the sky was gray and pouring rain. Worse, she realized that the dress she was wearing was white! Without a bra, her dress quickly became sheer and clung to her ample breasts. Students and teachers alike were stunned as their eyes fell on her. Her dress had been loose before and no one would've guessed such an endowed girl would not wear a bra.

As the water kept falling, her dress got nearly transparent, showing not only her nipples poking out, but the outline of her areolae. Lizzie crossed her arms over her chest to hide them, and kept covering until someone wrapped her in a blanket. After a few minutes and no sign of an all-clear message, Mrs. Palmer, her science teacher, noticed the girl shaking despite being wrapped in a waterproof blanket. She walked over to her and asked what was wrong.

"I'm...c-cold..." Lizzie stuttered

"Why? You've got a blanket. You should be quite warm." The matronly woman replied.

"Miss, my clothes are soaked, and this blanket isn't helping me much."

"I see. Well, just take off your clothes."

"What?"

"Quickly! You're going to catch a cold if you don't."

Lizzie held the blanket to her body as much as she could before bending over so it wouldn't drop to the ground as she let it go. She moved her hands to her shoulder straps and pushed them down, forcing her dress down her body until it dropped to her ankles. Liz held the blanket again before stepping out of it. She kept the blanket closed with one hand, then bent down to pick up the soaked dress. She handed it to Mrs. Palmer, who wrung it out and placed it in her coat.

"I'll keep this until we're back inside. I hope you're warming up now." The teacher said

"Actually, I am." Lizzie replied.

"Good." Mrs. Palmer said, turning to leave.

Fifteen minutes pass before the all-clear is given. As everyone makes their way back to class, Liz is stopped by the janitor.

"I'm afraid I need that blanket back. It's supposed to be in the lost and found. I just couldn't let you freeze to **** out here." He said.

"Please, sir. All I have on are my panties. My teacher took my dress to keep it dry." She begged.

The janitor turned his back and waited for the blanket. Liz looked around, hoping she could make a run for it, but the only way to get inside was past the janitor. Luckily, no one else was around now. Liz tentatively flung the blanket onto the janitor's shoulder before wrapping her arms around her breasts. The janitor just walked away, even turning in another direction so he wouldn't see her behind him entering the school. Liz was thankful for his thoughtfulness and ran towards the school. However, the rain-soaked pair of panties were already saturated from before, and now that they were getting pelted with more water, they began to sag. Just in front of the door, they dropped to her ankles, causing her to trip. She fell through the door, her ample bosoms cushioning her fall onto the cold tiles. Her wet skin slid along the floor for a few feet before she skidded to a stop. She finally was able to look at her feet and was frustrated to see her panties twisted around her ankles. She tried to untangle them, but in their wet state, it was nearly impossible. She kicked off her shoes and just pulled the panties off before putting her shoes back on and trying to untangle them. Of course, it was now that she realized she was naked in the school hallway and ducked into the nearest restroom to try to dry and untangle her underwear. Her efforts proved pointless, and she threw them in the trash. 

It was at this point that she was surprised by someone entering the restroom!
