This is a full body to body FBSM slippery massage using a special gel. Invented in Japan using Nuru gel, a tasteless, odourless, clear slippery liquid devices from seaweed. It usually starts with a shower or bath as you both need to be wet for the gel to work better, it is then performed on either a blow up plastic mattress or a bed covered with latex sheets. The escort covers you in the gel then runs her entire body on yours. Google Nuru for lots of videos!
