Her classmates

Lizzie entered the school and immediately headed for her locker. At this rate, she wasn't quite going to be late to homeroom but she'd be cutting it close! Today she was just focused on making it through the school day, and didn't have any embarrassing antics planned. After all, she couldn't get stripped naked every day, even if she'd prefer otherwise.

Nearby, Paul, a boy in most of her classes, peeked around the corner and smiled at the sight of Lizzie, dressed in a simple t-shirt and skirt. He nodded to his friend Joe who turned the corner and walked past Lizzie. The boys had both seen Lizzie in various states of exposure several times over their high school years. Indeed, by this point, after so many humiliating experiences, Lizzie's ditziness was legendary. So today, the group of friends had resolved to put it to the test. They wanted to see how much they could strip Lizzie before she noticed. And seeing her undressed was certainly not an unwelcome side effect.

Lizzie, completely unaware of their plans, closed her locker and began briskly walking towards homeroom. As she rounded the corner, Paul stepped forward and bumped right into her. Paul stumbled back, but Lizzie fell to the ground. She instinctively splayed her legs wide open, showing off the black pair of bikini-cut panties she was wearing that day. Lizzie had long ago trained herself to instantly adopt the most embarrassing positions possible in any trips or falls.

"Oh, sorry about that Lizzie!" Paul quickly said as he extended a hand to help her up.

"Ah, it's alright." Lizzie replied, letting Paul help her back to her feet.

Behind her, Joe snuck up and carefully placed his hands on Lizzie's skirt. As she stood back up, the skirt stayed in place on the floor.

"You okay?" Paul asked.

"Yeah just a little banged up." Lizzie said, rubbing her head, "I'll be fine."

She had, of course, felt the skirt sliding down her legs. But, sticking to her ditzy persona, pretended that she didn't notice the clothing loss. Maybe today won't be so boring after all! she thought to herself.

She and Paul began walking towards homeroom together while Joe picked up the skirt to stash it away. Phase 1 was a success! Now began Phase 2.
