A ReachAround for a woman

[superduper]

Sergeant Hartman in Full Metal Jacket said, "You seem to be the sort of person who would fuck a person in the ass and not have the goddamn common courtesy to offer them a reacharound", and it is when they jerk someone off who is being fucked in the ass by them. So, to give a woman who is being fucked in the ass the stimulation would be to finger their pussy whilst fucking them in the ass; but is this done in porn yet ?
