It’s clear you are on his side, and it is clear that she was in slow mode, for what ever reason. The moment he came up behind her she said no, no means no, no he kept trying only the head and I will take it right out. Like I said , he lied multiple times. She was out of it for sure, he had the opportunity and he took it, not only kept filming, he posted it, which is most likely why she did want it video. Trust she is not the first to be posted with out consent. No way to prove who the asshole is they make sure only the women are seen. This is all a game to them, they feel they are entitled to do as they please, they are men, I do not call them men, real men do not act this way
This can't be the first time she's been fucked in the ass, but she is still learning to get used to it. Sounds like she started enjoying it for a while, but then it began to hurt too bad. It'll be longer next time, and every time afterwards.
