Her lips curved as she ran a hand through his hair.

He looked into her eyes, and again, his lips curved.

He looked at her, his lips curved in a half smile.

His lips curved into what might have passed for a smile.

His lips curved as he rolled on top of her.

Her lips curved when the water turned a pale blue.

His beautiful lips curved in a smile that knew all about her.

For the first time, her lips curved at the corners.

His lips curved slightly before he brought the wine to them.

Her lips curved in a smile but did not curve.
