Shorts fall!

Lauren gasped as she felt her shorts fall around her ankles. This caused a few things to happen all at once. First of all, the two pale, oversized and slightly deflated orbs of her ass sprang into view, warbling excitedly with her motion. Seconds her shorts tangled her feet together, but the treadmill kept moving. This caused Lauren to teeter, then, with a squawk, loose her balance and fall forward. Unfortunately the treadmill shot her off the back where Lauren landed in a crumpled pile, bare ass up.

Everyone stared, too stunned to move. Lauren's pale ass was pointed straight at the ceiling, her smooth shaven lips clearly exposed between her thick thighs. Lauren, totally dazed, finally struggled to her feet. Gasping, she bent down, tuggin her shorts back up. Unfortunately, with the elastic snapped, she had to hold them up or they'd just fall straight to the ground again!
