Only through the first so far (started a new job, so time's a bit more limited suddenly) but it seems really nice. Suggestions on it: First, talk more about feelings/attitudes/etc...I was able to infer some things from the text, but the end -- after the photographer had left -- was the first time any discomfort with him was really made plain (before it was only 'nervous')

"I realized I didn’t even feel awkward now as I slowly stretched flipping. I heard a snap and smiled seductively as I used my body to tempt." Seems awkward - 'Flipping' was vague (flipping positions? over? him off?) and I didn't understand the snap (I assume a joint, but not sure...at odds with seductive? I don't know).

At two or three points in the story you also switch from 1st to 3rd person, and there was one your that should be you're...otherwise pretty clean, technically.

I didn't find the length at all bad. Yes, I'd love to hear more, always, and I think more could be said, but it wasn't in any way incomplete.
