Cooper smiled at the involuntary caress of Sarah's fingertips against his cheek. A direct hit. He kissed again, more lightly this time, then drew her hand a little farther away from her and kissed her wrist. There was the catch in her breath he had been listening for, and a hint of a shiver. He turned her hand until the back was to him and closed his lips around one dainty knuckle.<br/><br/>So far so good; time to turn it up a bit. Cooper's thumbs kneaded Sarah's palm until her fingers splayed again. He paused, considered them, and then very slowly took her index finger in his mouth and gave it a gentle suck.
