I get that, but how many angles are really needed? Attached are two that I would characterize as fairly easy.
The first is more "arty", without genital close-ups, and the second is more graphic and "pornish", so it's possible to get both softer shots and hardcore shots showing an open pussy and both tongues working her clitoral hood- something for everyone.
Also, I've noticed double pussy licking is much more common in lesbian threesome scenes- how do you account for that? I understand that for various cultural/historical reasons male porn stars might have hang-ups about their tongue touching another guy's, hence the paucity in fmm scenes, but I don't see why it's any more difficult to pull off for ffm than fff. This indicates to me that mainstream porn is still somewhat fixated on depicting men being serviced. What I'm saying is I'd like to see more female-centric activity in mixed-gender threesome/group scenes.
