Running

Debra and Kyle led Lauren over to a treadmill near the front of the gym. They passed all the other contestants. To Lauren's horror, every one of these overweight people seemed to be fairing better than her! Some of these people weighed nearly 300 pounds, how was she the sweatiest and most out of breath?!

Lauren dragged her bare feet onto the treadmill. Did they really expect her to run with no shoes? Apparently so, because without even giving Lauren a chance to catch her breath. Lauren squeaked as she began walking to keep up. After about a minute Debra increased the speed. Lauren now began jogging. She could feel her body shake and jiggle. Why did they have to pick the treadmill in front of everyone?! Peaking over her shoulder, she saw the other contestants, the trainers, the crew and the cameras all watching her. Then she looked down. Her pale thighs vibrated with every step. Her stomach was warbling like a bag of jello. She could only imagine what her ass was doing?

Debra upped the speed one more time. Now Lauren was full sprinting, running as fast as she could to keep up.

Unfortunately, what Lauren didn't realize was the elastic in her shorts was already stretched to the breaking point. The extra strain of her running like this was too much for them. So her shorts snapped, sliding down in an instant, leaving Lauren naked from the waist down!
