It's possible there'll be a bit of a mess at the end of the scene perhaps some semen or female ejaculate or even pee or blood on the surfaces where sex was happening.
It's our policy that the Shoot Producer provides equipment for cleaning up, but the models do the actual cleaning (if it's necessary).
We're not cleaning a crime scene here ! Typically, this is simply;
Soak or wipe up fluids with a paper towel or toilet paper, dispose of in trash can or toilet
Spraying some cleaning fluid on the area, wipe down with a wet rag
Rinse rag, wipe down the area again
