In the end, the Duke solved my dilemma on his own. He stayed with me, in the bed, and he couldn't help but take the opportunity to embrace me tightly.
He dragged me in his arms. To keep me warm, he said. However, he didn't take advantage of his strength to force himself on me: he just slept with his head on my shoulder.
His hands did wander on my body until he found a comfortable position. Yet, his touch was gentle and careful, nothing to do with the sensual caresses of a while before.
I fell asleep late in the night when I got used to the Duke's presence. So, I wasn't surprised when I woke up alone in bed.
What surprised me the most, though, was that the Duke didn't leave the room. He was standing near the chimney, lighting a fire.
I turned in the bed and decided to sleep some more. I closed my eyes and cuddled under the covers.
