Is this what your talking about:Nuru Massage, also called Body Slide is a massage performed with a special kind of massage gel called Nuru Gel. The word nuru comes from the Japanese language and it means "slippery", but we tend to believe it was also originated from the name of the Seaweed used in it, called "Nori". The nuru gel is very cool and comfortable when you apply it to your skin, when getting a nuru massage the masseuse will rub your entire body with the nuru and slide on you for a perfect body to body massage.

The nuru gel is made from deep seaweed (Nori) and is transparent, tasteless, odorless, extremely slippery and smooth. The gel is cool when applied to the skin, when getting a nuru massage the masseuse/masseur rubs the body of the client with the nuru gel and slides on it for a sensual body to body massage.

From my research, a nuru massage is a massage where the masseuse would use a special gel and she would use her whole body to massage the client's body. They often both do it naked and sometimes this massage form may end in a form of sexual activity.
