Her shorts rip even more

Marinette gasps as she realizes her underwear is on display for the class to see. She instinctively puts her hands over the tear only to find out the rip is too big.

Instead, she tried to back up onto her desk. Unfortunately she didn't notice the belt loop on the side of her shorts getting caught on the hook holding her bag on the desk as she turned until it was too late.

RRRRRIIIIIPPPP!!!

The left side of her shorts split open, exposing even more of her blue panties for the rest of the class, many of whom were now recording her.
