this is so romantic, I love it! Maybe its the intimate nature of your voice, or the story itself. I like to believe its a combination of things that your do that just draw you into this wonderful minds-cape where you can envision yourself in such a moment.
What I care for in the most is that your partner in the fantasy is treated with such adoration. There is no chastising or lack of gentleness, you just get the sensation regardless the partner you would still treat them with such tenderness.
I love romance stories, and this story is definitely going up there as one of my favs from you.
