Sploshing

One sexual obsession that includes spreading the body with dirty, wet substances is called "sploshing." Food products such as whipped cream, chocolate sauce, custard, cake, and sauces are often used while sploshing. You can also use other sloppy materials, like mud. The sensation of these substances being spread on one's skin or witnessing someone get sloppy can both trigger sexual desire in people.

Wet and messy (WAM) fetishism is another term for sploshing.

Sploshing experiments can get quite messy. To greatly simplify cleanup, couples can limit their activities to a bathtub or shower stall. A much quicker and simpler cleanup can also be achieved by placing old sheets on top of a sheet of plastic.
