Sounds like she's hitting on you.  Enjoy!

Makes me wonder, how long has she been in the business? Full time or part time? Was she always an escort or did she transition into it from some other area of adult entertainment?

This is obviously not how it's 'normally done'.

Did you say you went to her private incall? Or did you go to an agency, and selected her? Not entirely clear from your post.

If this is not how you prefer to relate to your ladies, you'll need to make that known.
At least you know she likes you..

Obviously, this isn't the way it's normally done, but it may be a harbinger of things to come.  The Internet has opened this business up in a way that was unthinkable 10 years ago.  Frankly, I think that taking the wraps off in healthy ways is a good thing -- whether this is an example of that is the question.

"What should I make of this"

If you weren't paying her, do you really think that this would have happenend?  Obviously she likes your money.  Nothing more, nothing less.

I've made a few friends of providers and had great times outside the bedroom.  It can be a great time if you go into it not expecting a hummer at the end of the night (might happen, but probably better not to ask).

One can never have enough friends.

I've had that happen and it turned out pretty well, with us either going out for awhile or becomming pretty good friends. Sounds like she's hitting on you. Did she mention anything about $$ for the evening? If not than she obviously enjoys your company and would like to see you outside of busness. If you can handle it than enjoy.

Seldom

If you had a good time with her, see how it plays out just don't lead her on. Or you can ask her cause you don't want to have any misunderstanding about the situation. If you don't feel comfortable let her know that you want to keep it strictly to business.
