Her reaction

Mistress obviously liked the letter.

I was surprised - I did not expect it to have such a positive impact.

She said it was very submissive.

I guess (sadly) that it is true, and She can see and so accepts the truth of it.

I am glad it helped me, and apparently Her, to clarrify things. But I'd be lieing if I did not say that my heart is heavy when I think of what I have lost - thrown away over the years, but lost.

My loss, David's gain. And Her pleasure. And that is the point - Her pleasure.
