Yes, bad mistake

Distracted by the thoughts of all the smiles and glances she received on her way to the machine, she forgets her normal routine of checking out the settings, and with one hand on a side bar, she presses the start button.

“Shittttttttttt” she lets out a shocked cry as her feet are dragged from beneath her as the belt begins at sprinting speed, obviously the last person on here finished with a burst. As her feet are propelled from beneath her she desperately scrambles to keep her balance by holding onto the bars, but even so, she hears a laugh from behind her as people look her way after her initial scream.

From the watching audiences point of view, the sight is of the back of Dani, her perfect ass encased in her tight pants flexing wildly as she kicks wildly to regain her footing, and the smiles that appear on the watching faces are from a mixture of amusement and arousal at the sight.
