Lauren's too excited on the treadmill

Lauren had arrived here in a state of heightened arousal. But now, with this tanga digging into her womanhood, half naked and exposed? Now she was about to cum. Each step edged her closer to bliss. Her legs felt rubbery as the pleasure between her legs increased. Oh god, she couldn't wait to cum! She no longer cared where she was. Her eyes rolled back in her head as drool escaped the corner of her mouth...

This distraction proved to be her undoing though. That, combined with her oversized shoes and poor gym outfit, caused her to stumble. She squawked loudly as she fell. The treadmill threw her backwards, where she crumbled into an undladylike pile with her thong clad ass pointed straight up. The gym erupted in laughter as Nancy the trainer shook her head as she helped Lauren to her feet.

"That wasn't even that fast." Nancy chided the stunned Lauren. "You must really be out of shape!"

Then Nancy noticed two things. One, Lauren's extremely excited nipples under the bikini. Two, some clear moisture pooling down Lauren's thighs, that wasn't just sweat. Nancy's eyes narrowed. This slut was getting off on this! No wonder she dressed like a slut, she was an exhibitionist!

Well, if this pudgy, out of shape loser wanted to show off her body, Nancy was going to give her what she asked for and then some!
