When a woman is held like a bowling ball, with one finger in her vagina and another in her anus. One of the fingers must be a thumb. NOTE: Switching fingers is unsanitary and could lead to infection.
Greg had his thumb in her vagina then slipped a finger in her anus. She screamed, "kingpin" and continued to enjoy herself.
