Her jacket became caught in the floor drain she had fallen on.

(Chapter originally by Teraton on writing.com)

With the chair still stuck to her hands, getting up off of her back might have been a problem. But, as Toriumi allowed herself to smile for a brief moment, she knew she no longer hand to worry about that. It would be a simple matter to push herself up to a standing position, with both of her hands unencumbered by things like clingy furniture. Taking a deep breath, she braced her legs to push herself up, giving herself slightly more modesty; she was still bottomless, with a fairly clear view of a tuft of brown hair, but at least she wasn't in a spread-eagle pratfall position anymore. Flexing her fingers slightly in celebration, Toriumi placed her palms squarely against the bathroom tile, and propelled herself to her feet!

SMACK

"Oh, son of a-- what now?!"

...or at least, she tried to. Instead what happened was, after the initial thrust upwards, there was a tug from somewhere around her upper back. Apparently her jacket had caught on something; at least, the all too familiar sound of tearing fabric seemed to indicate so. Not enough to tear the fairly thick garment off, but enough to keep her from getting up, and enough to bring her bare butt smacking back onto the cold, wet bathroom tile.

"Great," Toriumi muttered, "sure. Let's tear everything off! Why don't I just march back in and teach class stark naked!" Toriumi barked a short laugh, before lying back against the drain tired and defeated. "Maybe that'd get them to pay attention," she mused, "a little full frontal!" Isako spent a few more seconds still on the tile, before sighing. She knew she had to try again; she couldn't let the frustration allow her to make things even worse. As much as it pained her, she might have to undo her jacket and slip out entirely. It might take a while, but maybe she could come back to it once she was on her feet. She could just brute **** her way up, but her panties had already suffered from that method. Either way, the class period wouldn't last forever. Forget about grading quizzes-- anyone who stopped into the bathroom in that time was going to get an eyeful if she didn't move soon!
