Several veterans have told me to forget about finding a nuru massage parlor in the US at least, as they are purely a Thai/Japan/China thing. It's possible one exists in Canada, as the laws are much less stringent, but otherwise you'd have to jump on a plane. On the plus side, I have found a couple of places which offer soapy massage (one in the US, a few in Canada). At any rate, I love the website www.nurumassage.com, which I'm sure you've been to alrady.
Some private massage girls may offer it, or its cousin the body slide. However you will NOT LIKELY find it in any spa in the USA, since it requires nude body to body contact for a fee, which in almost all jurisdictions is illegal. Maybe, just maybe, it would be legal in Nevada, possibly.
Studio 18 in York, PA offers something like a body slide, I think for about $200. This place is a little unusual in that it is "self-service HJ"....bizarre, but a very hot black chic named randi or brandi.
