From her account he does come off as an entitled horny guy, that said the moment a woman wraps her lips around a dude's dick is the moment from which many guys are going to assume sex is going to happen and pursue it. That's a "non-verbal cue" too.
I think it was a case of a girl who thought she was gonna have a relationship or something meaningful with a famous/successful guy and that guy who thought he was getting his weekly hook up from a party/club. When she realized that she was just going to be a "hook-up" the night turned sour for her, he didn't read that because he was still thinking about her sucking his dick a few minutes earlier. They both seemed to have misread the situation.
