When two people are gently kissing.

When two tenderly kiss, they breathe their breath into each other. It is like a fragrance in which they feel wonderfully permeated.
Receive, Lord, the breath of my soul entirely into yourself. Do not turn away from it. I breathe it entirely to you. And you breathe your breath entirely to me – after all, it smells completely of you – let my breath be filled with your lovely scent.

(bl. William of Saint-Thierry /around 1080–1148/)
