Disaster on the Stairmaster!

Janice led the panting, red faced Lauren's to the stair master. She guided Lauren onto it and began pressing settings.

"Wait... Let me catch my breath..." Lauren gasped. Janice ignored her and turned the machine on. Lauren gasped as the stairs began rotating downwards. Lauren scrambled to keep up, climbing upwards as the never ending rotation of stairs began. Lauren's thighs and butt began to burn instantly with the marching. She dragged herself up another step. Then another. Oh god, she was dying! Sweat poured down her face.

Finally, the pace of the machine was too much and Lauren missed a step. The machine kept rotating downwards, until Lauren stumbled off the back of it. She yelped loudly, falling on her butt. The machine kept right on rotating the steps. A corner of Lauren's stretchy pants was caught in the stairs, and began pulling into the machine. Lauren watched in terror as the machine seemed to eat her pants, pulling them down off her hips. In less then three seconds Lauren's pants were around her ankles, revealing her spanx from the waist down! The machine kept pulling, yanking off her shoes along with her pants! Her lifts flopped out as she was left barefoot in Spanx sitting on the ground, before Janice finally reached controls and turned off the machine!
