And I could hear his breathing grow audible in the second hour.

My breathing grew so loud in the silence that I could stand it no longer.

She was still there two hours later when his breathing grew more shallow.

His breathing grew less labored as he made contact with her.

I kept my hand moving until her breathing slowed and grew deep.

His breathing grew very short, compelling him, several times, to stop and rest.

Her breathing grew more regular though it was still far from normal.

She heard his breathing grow short as the words echoed between them.

The closer she came to him, the tighter his breathing grew.

Rachel's breathing grew quicker, but she could not seem to get enough air.
