Liiino the question for the jury was whether she was capable of consent and whether CE could reasonably believe he had it.
It wasn't about "fuck me harder" being consent (a 9 year old isn't capable of consent even they said the same, for example. If you're not capable of consent it doesn't matter what you say)
The second question is whether CE could reasonably believe he had consent. So far this has hung on the point that he didn't speak to her before he stuck his tongue/ cock in her so how could he think he had consent?
His defence, which the court where allowed to hear thanks to the court of appeal, was that the woman had used the same language and had the same outcome with 2 other men who she did apparently, have consensual sex with (fuck me harder, same position, and forgetting the next day) therefore this indicates that she wanted a total stranger to do the same, mid shag with a man she was having consensual sex with.
