When engaging in rough sexual intercourse on a sandy beach, the male sticks it up her anal cavity and continues with anal until he goes inside her rectum. He continues to pull out quickly leaving the loose anus open and throws in a handful of sand off the beach. This combines with the already present semen to form an unstoppable cement-like combination which when dry, the female will later refer to as a fire in her asshole.
