Jon's continued effort, while hindered, was steady. But he felt like he was exhausting himself. In short order, he was short of breath and leaned one of his manicured hands against a tree to steady himself and recover.
This had been a problem Jon had long dealt with, and he should have known better then to push himself, but this was an emergency. His unusually narrow waist constricted his diaphragm, making breathing hard when doing anything more than walking for for an extended period. It was just his luck that his luck that his waist was almost half the diameter of his hips, giving him an extra waspish appearance.
Once he had his breathing back under control, he continued on at a walk this time. While quick, it was not the run he wished he could achieve. Still, he pressed on towards Sarah's.
