The dreamy little smile that always appeared when she talked about him played on her lips.

A faint smile played on his lips, then was gone.

A half smile of wonderment was playing on her lips.

But she was watching us now, and a slight smile played on her lips.

The girl turned toward him, the laugh still playing on her lips.

The vampire only sat there, smiling, a small smile that played on his lips like the light.

He allowed a smile to play on his lips.

A hint of a smile played on the storyteller's lips.

But an absent-minded smile was already playing on his lips.

Even though she stood in shadow, he could see that a little smile was playing on her sealed lips.
