Asked the teacher to be excused for a trip to the bathroom

(Chapter originally by Phantom Pen on writing.com)

"E-excuse me, teacher." Chihiro stammered, her nervousness failing to raise any suspicion considering her normal demeanor. "M-may I... may I be, uh, excused?"

"Hm? Need to take care of something?" Ms. Miyahara asked. "Well, you did just answer the question correctly, so... go on ahead, Fushimi. Just don't take too long!"

"Th-thank you." Chihiro said, giving a small bow before backing away and carefully making her way out of the room. Thankfully, Chihiro's small steps and halfhearted bow could be chalked up to her fabricated need to use the restroom, and nobody seemed to think anything of it as she exited the room.

Once Chihiro was in the empty hallway, however, her pace changed. Her walk turned into a solid run, one of her hands gripping the tear in her skirt tightly to keep the damage from spreading.

So, with several deep breaths to steel herself, Chihiro carefully pulled her skirt down her legs, keeping an eye on the bathroom door in case someone else entered. The last thing Chihiro needed right now was for somebody to come in and see her standing there naked from the waist down. It was embarrassing enough that she was bottomless in school in the middle of the day, an audience would just make things worse.

Holding her skirt in her hands, Chihiro held the damaged garment up to her face, closely inspecting the damage. There had to be something she could do to at least temporarily mend the damage. Maybe if she could get her hands on a stapler? Or she might be able to find some safety pins to hold the tear together... There just had to be -something-.

As Chihiro pondered what to do, her situation only got worse when-
