Nothing; Katie loses her balance

"Thought you might need help," her ride said, his eyes fixed on Katie's pale plump buttocks.

"No!" she protested. Katie yanked at her jeans, trying to pull them up. She caught a toe in the pants leg, heard a ripping sound, stumbled and fell sprawling with a shriek.

"Are you all right?" he asked.

"Yes!" she protested. "Just go wait by the car, okay?"

"But your pants?" he said.

"What about my pants?" Katie felt about. "Oh."

Her beat-up old travel jeans had finally failed her. One leg had ripped out of the crotch seam. Her bladder still pressed. The guy was still there, and she far from home, sprawled in the bushes down an embankment in a pair of destroyed jeans.
