Kink is any sort of sexual play that is out of the ordinary. In most cases, it involves two or more people, and role playing. In the photo below, we’re looking at the filming of a kink scene depicting an army physical examination.
An example that’s not quite kinky would be, “Let’s fuck on the kitchen table.”
An example of kink would be “I’ll wear a diaper, and you treat me like a baby, pull the diaper down and spank my butt.”
