Class ends, but she can't get dressed yet

As the school bell rang to indicate the end of the class, Anna reached her arms into the air and stretched in celebration. She'd done it! She'd gone through with Claire's ridiculous dare... well, not really Claire's, it was more of her own idea... but still, she'd done it! The most daring dare she'd ever dared. While the rest of the class started to migrate towards the door, most of them keeping their eyes on Anna, Claire placed her backpack onto Anna's desk, unzipped it and placed Anna's panties onto the desk in front of her.

"Uh, excuse me." Mr. Weathers called out. "Ladies, this is not a changing room. I do not want your dirty laundry scattered over my furnishings."

"I was just going to get dressed, sir." Anna replied.

"Not in here, you're not. While your outfit has certainly made this a more interesting lesson, Anna, I don't want to encourage other students to start dressing and undressing in the classroom. Put the panties away and go and get dressed wherever you got undressed."

"But sir," Claire pleaded "The other classes have let out as well. The hallway will be filled with other students!"

"Being seen by her fellow students doesn't seem to have bothered Anna so far." he replied.

"Come on, Claire." Anna said, grinning weakly. "It's just across the hall."

"Sorry Anna." Claire said as she stuffed the panties back into the bag.

Resigning herself to being seen by even more people, Anna stood from her chair and followed Claire towards the classroom door. The other students lined up either side of it, a few of them muttering encouraging comments to her. Claire held the door open for her, and so Anna stepped into the hallway.

She could see one or two of her classmates who had left the room were speaking animatedly with a large group of other students, seemingly explaining what had just happened in their math lesson. The other student's faces turned from cynical disbelief to open-mouthed shock as Anna stepped into the hallway wearing nothing but her white knee-socks and sensible black shoes. Her embarrassment intensified, but she didn't want to show any weakness by covering up. Instead she waved at the group, muttered a 'Hey', and then followed Claire into the bathroom.

"Holy hell that was intense." she said once the door was closed. She leaned against the cold tiled wall, rested her head against it, and let out a deep sigh of relief.

"So, ah, you want to get dressed straight away?" Claire asked. "Or do you... you know... wanna relieve some tension first?"
