My first commentary for this story is to state that something akin to a 'predictable ending' is not exactly an issue. The inclination comes together as the story progresses, but the on surface dressing is that of a distant love affair, and it has this sort of past emotional resonance. Then again, if the prose and story itself is solid, I can forgive such things.
But I don't think there is much that must be forgiven here. I think, if I was to make a creative suggestion, it would be to avoid using the same words within a sentence unless absolutely necessary. That said, the prose has very few bumps, and is exceedingly smooth. Your sentence structure isn't jerky, it isn't oversaturated with style above substance. You focus on details, and place them together in a very simple manner. At the same time, you also do this in a very colorful way that draws the flavor from your story.
The minute details that you cover, the experiences and dressing and character quirks all have meaning, they are all fun to investigate, and overall...you have painted some extremely fine tuned imagery when you feel the need to invoke it.
I also am glad that you are not afraid to let dialogue speak for itself in a story like this. All too often, an author has a tendency to over-analyze their subject material. They go into too much inward based detail, beating into the head of the reader what they MUST think rather than allowing interplay. The dialogue is, at times, a great driver for your story simply based upon the fact that you do not clutter your dish with trim.
Overall, I would say that this is one of the most engaging pieces on this forum. As a former Golden Feather winner, I can see that the praise is much deserved. You have created a very beautiful and erotic story here, and you should be really proud of your hard work.
