The breath heaved raw in his throat before he found shelter.

He took a deep breath of air and his stomach heaved.

Her breath was heaving in her chest from running.

Her breath was heaving, shuddering as she tried to calm it.

Her face was buried against his throat as her breath heaved in and out.

Slowly she picked up speed, until her breath was heaving.

His breath was heaving as he gripped her hips.

He felt a stitch, growing rapidly as his breath heaved in painful gasps.

Her breath was heaving, though she was struggling to even it.

He'd been right about the virginal part, he thought while his breath heaved.
