Oh, he thinks she's expert enough.

One hand slides to the curve of her neck, thumb and fingers resting against her jaw. As she deepens the kiss, he slides his hand up into her hair. The other hand sits at the small of her back, pressure light but firm there. She's free to get as close as she likes.

There's the softest groan when she nips his lower lip and pulls away. "Right. We're celebrating," he says, more to remind himself than anything before he leans in to capture her mouth with his again. After all, why stop at one kiss?
