nude reverse

Does anyone have any tips they can share on what to do during a nude reverse. I don't want to make the woman feel like I'm just groping her. And with a nude reverse, are you allowed to rub her area down below as long as there is no penetration?

I've only seen SPs for the most part, and have never really tried MPAs because I figured there were too many restrictions. But recently, I'm considering them because I heard you can still get pretty far with them in terms of getting a good time. So my question is, what are you allowed to...

I know touching the mpa is generally off limits and rightly so I may add... However in the case of body-slide and nude reverse there's the obvious exception. Do any guys or gals feel uncomfortable or approach with caution

The cheapest NR option would appear to be at Airport Golden Spa: $90 for 30 min. Does anyone know of other MP's that match or go below this price point?

Without naming any MPs or getting anyone in trouble, can some of you please explain in detail what you get/expect from Nude Reverse? Okay, I know it means that you get to massage the girl, but I'd like a sense of how far you are allowed to go with the better girls. Is it just rubbing their boobs...
