Pulled up panties

A sensation that was almost unnoticable was quickly becoming a problem in Sarah's pants. One way or another when her backside hit the pavement her panties got hiked up and started to put pressure on areas best left alone. Sarah had a long way to go to her homeroom class and time was pretty tight. I'm sure I can tough it out Sarah thought as she pushed on towards her destination, but with every step her panties were climbing higher into her lips and becoming increasingly troublesome. "Maybe I should look for a restroom after all"
