Katie makes it to the end of class

Katie is determined not to mess her panties again. She focuses on her essay and tries to block out her stomach pains. At first it works, but ten minutes later Katie feels pressure on her anus.

Katie slides her left hand under her skirt and places two fingers on her anus to keep the poop in. She hears laughter as some of the students see this move. Katie starts sweating as the minutes tick down. Her legs shake with fear.

Two minutes left in class and the poop tries to **** it's way out, but Katie clenches her ass cheeks and forces her fingers up her anus. Katie manages to hold on but her panties now have skid marks.

The bell rings and Katie rushes to grab her things.
