Time to switch places

"Katie," Sarah said with a grin, "Time for you to do a little hitchhiking of your own."

"Wait, what?" Katie said looking confused.

"I dare you to hitchhike naked," Sarah said with an ever-widening smile, "Like you made me do yesterday."

Christa smiled, and Katie reluctantly pulled over. Removing her towel and stowing it in the trunk, Katie stood beside the road. Now all three girls were naked again, their "clothing" certainly didn't last long, as it was barely 10 am and already they were once again naked.

Sarah got into the driver's seat and turned to Katie. "I will drive down the road and wait for your you a few miles down. Same as you promised, if I don't see you for a while, I will come back for you." Then Sarah started the car and drove off, leaving Katie with nothing but the view of her own car driving away.

Katie stood, very naked, on the side of the road. Slowly she extended her arm and put out a thumb in an attempt to flag down a car. The first vehicle that passed was the bus from before. The driver was busy dealing with a naked girl of her own to notice one on the side of the road. The glimpse Katie saw of the adventurous college girl looked like she was crying and covering herself with her hands. As the rest of the bus flew past in a near-blur, it looked like a few students were looking for something and a couple others were laughing to themselves.

It was a minute before another car passed, which also didn't stop. Katie was beginning to fear no one would stop and Sarah might leave her here when she heard a car pull over. She looked up hesitantly.
