It is your last class, which is gym, as you all have to run a few laps around the gym, as your teacher excuses herself to the bathroom. "Okay class, I'll be right back, I've got to go to the restroom." She says, as she hurries off to the bathroom, and gets into one of the stalls, and pulls down her pants and underwear to her knees, before sitting down onto the toilet seat, as she lets loose into the toilet. "Aahh~, that feels so good to let out!" She says to herself, in relief, as the rest of class are still running laps around the gymnasium, including you, too focused on getting good grades, and not paying attention to anyone around you.
