What happens at the close of anal sex when the penis is removed from the anus as it attempts to clear the sphincter. During this process and just as the penis is removed anal fluid is gleaked from the spincter similair to when spittle is ejected from under the tongue when gleaking.
After a vigorous anal reeming I slowly pulled my penis out with the anticipation of a mess but to my pleasant surprise it was just a few airborne drops of anal gleakage that landed on my hand.
