One of my favorite things is the moment of ancitipation when a girl straddlers over another girl's face with an expectant face and a wet pussy all in a POV shot. Then pauses before dropping down. The tension is there. The cunnilingus is imminent. The bottom girl knows she's can't run from the pussy, it's going on her mouth no matter what and she's going to service it with lots and lots of cunnilingus no matter what. Bonus points if the top girl's face is also wet with the bottom girl's juices, so there's a sense of "I licked you and stuck my tongue inside your pussy, now you HAVE to return the favor!"

Unfortunately some artists exclusively draw the moment of anticipation but never draw the payoff.
