When giving anal to an individual that has not recently done a poop. It requires at least one male so the penis can be put into the others asshole so the penis and oncoming poop connect with their tips causing the docking effect. The poo will be pushed back into the human body on contact with the penis. It can be used to help put turtlenecks back into the asshole on emergency actions.
