In a moment her breathing became even and he moved quietly away.

The only difference was that her breathing had become faster.

At the top she stood leaning against the wall; her breathing had become strange.

The old woman's breathing became more labored as she finished.

She glared back, and gradually her breathing became more even.

In fact, the poor man's breathing had become more ragged and coarse.

She rested on one elbow and looked at him for a long time after his breathing had become regular.

In the silence he noticed how uneven his own breathing had become.

The wait seemed endless but at least her breathing became less labored.

The breathing became louder still and started to sound like moans.
