The face that puts the passive is that it hurts or likes?

Well, I would say that a little of both things, he likes it because he is passive and it feels cool to feel his ass fucked. But a big cock like that fucking you as hard as he gets fucked in this scene, some pain has to be. When he is sucking and the other grabs his head to put his cock to his throat, it is already sensed that when he gets his ass he will destroy it and so it was.
