I am meeting an established "fetishist" when I travel to Chi-land in a few weeks to play. Thing is, I am not really into FS (yet I suppose!), I just like to role play some...but that said I still like for it to have a happy ending. So this person has a few postings, some of which say nothing about what she won't do, but others say "I am not an escort.". She has one TER review but I am not yet a VIP (I am a newbie have only seen one provider so far) so I don't know the juicy details. So...how can I find out if she will entertain, not FS, but at least some satisfaction ?

I would say you should go into the session expecting to take care of your own needs.   At a first time meeting if she doesn't allude to more than fetish play in her ads and postings you are unlikley to get more than what is advertised.  If you linked her ad you might get more insight from someone who may have seen her, or others who may decipher her ad.
