I had the pleasure of a nuru massage while traveling. We managed this well on an incall basis. She brought an airbed and small electric pump, sheets and the gel. All fit into a reasonably sized bag. The sensation is wonderful. One thing nobody seems to have mentioned: the gel is edible.
We started out with a warm shower together, very carefully making sure all the good parts were squeaky clean and tasted fresh. This took some considerable degree of attention and repeated trial to be sure we had it right.
