"Soaked" in the context of a porn video tag typically refers to a scene where there is a significant amount of water or liquid involved, leading to characters being wet and often slippery. This can involve scenes like shower play, hot tub sex, or other situations where individuals are submerged or splashed with water. It implies that the participants in the scene are very damp, and sometimes even drenched, adding an extra sensory element to the experience.
