Cake sitting is a sexual fetish where people sit on cakes for sexual pleasure. It is considered a subcategory of the "wet and messy" fetish (WAM), a form of sexual fetishism in which a person becomes aroused when copious amounts of a substance are applied to the naked skin, face, or clothing. The pleasure of cake sitting is derived from the tactile sensation of the individual’s body meeting with something that is moist, messy, and squishy. It is a fairly new and trendy sexual fetish.
