Her panties get locked to the chair...

Amy woke up about 20 minutes into the lesson, she had dreamed about raid bosses and xp farming and all kinds of fun things she wanted to do when back in her dorm. As Amy reached for her phone to check what time it is she felt something strange bellow her skirt, something... tugging at her underwear.

Amy looked around before quietly lifting up her skirt at its side to reveal her panties had a padlock on them! and they were locked to the chair leg! Amy panicked for a moment and tried to remove it, after a second of doing so she noticed she was making a lot of noise, a few people were giving her weird looks but had not noticed what exactly was going on. Amy quieted down and stopped drawing attention to herself, she had to think of a way out of this... before the end of class or worse... before someone noticed.

Amy weighed her options, the most obvious solution was to remove her panties but that created multiple new problems, she would be panty-less and would have to leave her panties attached to this chair! what if someone noticed her leaving them behind? and they surely would.

her other option was to find who did this to her... but that wasn't going to be simple, she cant just ask every student in the room "Hey did you by chance put a padlock on my underwear while I slept? NOT ASKING FOR ANY REASON REALLY"

Amy stared at the faces of her fellow classmates... who could have done it? they all looked so... innocent... Amy looked at the clock again, there was 15 minutes left of the lesson and she needed to think of something NOW.
