Cum Dodgers

Someone is going to have to explain why women act surprised when they get cum on there faces in porn. I'm pretty sure that they should know that is going to happen, so why are they surprised/upset when it does??? Even if the guy promises not to cum on your face or in your eyes or whatever. He lying, intentionally or unintentionally, because he has very little control and usually that results in bad aim, especially if he is a shooter.
To be clear, I'm not talking about amateurs...for the most part. I'm talking about pornstars or wannabe pornstars who have a few vids on the internet. They need to stop it, it can seriously ruin a very hot scene/movie.
