When you are going doggy-style on a girl, you give her a donkey punch. Then, while she is stunned, you reach into her anus and pull out her large intestine, string it around her neck, and strangle her to the point of passing out. Her passing out causes a tightening of the vaginal canal and a pleasurable sensation.
