In this particular scene from Blonde there is a moment where Bree, the main character/anal intercourse receiving lady, with the help of a middle man gives a blowjob while making use of a glory hole

Ripped down blonde is an enticing lady who entices her man, bends over and goes in for the deepthroat cunilingus through a glory hole. This she enjoys to the fullest of her fantasies, her body tossing around in mouth-watering pleasure as she lathers her partner’s pussy until no part of it is left untouched.
