Nyotaimori, Body Sushi Girl

Nyotaimori (Japanese: 女体盛り, "female body presentation"), often referred to as "body sushi," is the extremely rare practice of serving sashimi or sushi from the body of a woman, typically naked. Nantaimori (Japanese: 男体盛り) refers to the same practice using a male model. This subdivision of food play is originally an obscure Japanese practice that has attracted considerable international media attention.
Procedures
"Before becoming a living sushi platter, the person (usually a woman) is trained to lie down for hours without moving. She or he must also be able to withstand the prolonged exposure to the cold food. Before service, the individual is supposed to have taken a bath using a special fragrance-free soap and then finished off with a splash of cold water to cool the body down somewhat for the sushi. In some parts of the world, in order to comply with sanitation laws, there must be a layer of plastic or other material between the sushi and the body of the woman or man."
