Hmmmm, there are some lovely descriptions in there acacia. You have portrayed the power of the seduction and as well as hinting at the tension your heroine is experiencing as she has to wait for him to catch up with her desire.
A couple of points. At the start you say that the dinner had lasted an hour, but it felt like ten. Now I know what you mean, in that there seemed to be so much of it. Now this might be a cultural/linguistic thing here - but to me, if someone were to say dinner lasted an hour but it felt like ten, they would mean that it had felt as if it had dragged and would never end. Also...in the middle of the story she is wearing a dress, when he comes to undress her she is in shirt and skirt.
I look forward to reading more of you work.
