My advice would be to use caution with Natalie.  I've seen her face on Eros in the past, and then she had reviews, but I don't remember her going under the name Natalie.  The reviews, IIRC were generally poor to mediocre.

A lookup under the phone number on her add shows her to be working for DC Elite.  Most of the reviews of the girls working under that phone number are fairly poor.

I don't know if it's it worth it.  Are you ready to take one for the team or back off and let somebody else do it?  Me, I'd find another player and wait for reviews on this lady.
