To me, the most incredibly boring part of watching sex is seeing women get orally stimulated. I do believe that those who direct porn nowadays understands how incredibly dull this is to watch. Talented tongue or not, it just isn't in the same level of interest as seeing how far down someone can swallow a cock.
Seeing the guys' hot ass while he's doing cunnilingus? That's fine. Having him be pleased from behind from someone else while he's doing it, even better (if THAT is what is shown).
