Non-food mess

Other substances like oil, mud, slime used in a sensual way. For instance, covering each other in baby oil or lube to make slippery bodies (nuru massage from earlier – that’s a clear gel used for body sliding). Mud wrestling but make it sexual: perhaps outdoors or in a controlled environment, getting dirty and then cleaning each other. Some enjoy slime or paint for shock factor (e.g. pouring paint over a naked body as art/erotic mashup). Ensure anything you use is skin-safe. It’s more about the messy taboo feeling (“we’re not supposed to make a mess during sex, but we are!”).
