First and foremost, this is a business. You are paying money for service, exactly what you get depends on what she accepts and you propose.
That being said, there's no need to be an asshole and assume that just because you are paying her means that you can do anything you want, if there are things she's not confortable with, you might want to back off and not insist.
Caressing and fondling are pretty basic service that in general are no problem unless anyone gets too rough. Of course if everything also cannot or its a dead fish attitude then need to post FR so we know who to avoid
Ultimately I agree with bro rrtan89, be honest with what you want and treat her properly.
