A grim twist broke the serious line of his mouth.

But then the hard lines of his mouth bent, and he sighed at himself.

For the first time amusement softened the hard line of his mouth.

A bitter little smile curled the fine lines of his mouth.

She was still leaning toward him, and he could make out the line of her full mouth.

Saw the desperate tension in the line of her mouth as she fought to keep from giving herself away.

After many long minutes he turned back, resignation and frustration obvious in the set line of his mouth.

A slow smile softened the hard line of his mouth.

But the smile still eased the line of his mouth.

The line of his mouth seemed for a moment to have softened.
