Nothing had ever felt so young as her lips.

He drew her very tenderly close and their lips met like starved hearts.

She lent him her lips again for the faint brush of a kiss.

He was remembering too vividly the youth and freshness of her lips.

He kissed her because it came about quite naturally; he found sweetness sleeping still upon her lips, and felt that he had never been away.

I hope I haven't given you the impression that I consider kissing intrinsically irrational.
