Lotion play is a subset of the better known wet-and-messy fetish (WAM), which typically involves participants using food (such as pudding or whipped cream), mud, or paint as a lubricant to facilitate sexual activity.
In Japan, lotion play (ローションプレイ, rōshon purei), also known as gookakke or gluekakke (a play on words from goo/glue and bukkake), is a popular fetish, a form of Japanese erotica and prostitution request involving the use of copious amounts of lubricant, which in the Japanese language is referred to by the French loanword "lotion" (ローション in Japanese).
Lotion is available in concentrated form, to be added to hot water.
The main component in most lotion is polyacrylate.
