Isabel tries to pull her pants up

"Eeeek!!" Isabel couldn't help but let out a scream as her pants passed her knees, dragged down by the treadmill, attracting the attention of the few people in the gym who hadn't already stopped to stare. It didn't occur to her to let go of the treadmill arms to get herself out of this predicament, and instead reached down with one hand for her pants which had gathered around her shins at this point. Turning sideways, she stretched her hand down, her fingertips just brushing against the waistband of her pants which she couldn't quite reach.

Unfortunately for Isabel, the change of position meant the side of her hip made contact with the still moving treadmill. Everyone in the gym watched on eagerly as the treadmill slowly dragged Isabel's panties down, showing off half her butt to the onlookers.

Isabel felt her panties begin to slip down and let out a scream, suddenly coming to her senses and letting go of the treadmill. As her bad luck would have it, this shot her across the gym floor and completely out of her pants, which Kelly quickly snatched off the floor before running into the changing rooms.

Isabel stood up, giving the gym one more look at half of her ass, before pulling her panties up and sprinting into the changing rooms after Kelly.
