I had understood he roughly flipped her over and just penetrated her anus while her head was shoved into a pillow. She alleged that Brand pushed her down onto the bed and that she struggled to breathe during the incident. If you’re struggling to breathe, you’re not going to have the breath to support speaking.
But she never actively consented to anal sex: he just flipped her over and did it anyway.
If the jury believes a complainant's evidence that she agreed to sexual intercourse generally but expressly refused anal sex, and the defendant proceeded anyway, that can amount to rape.
Conversely, if the jury has a reasonable doubt about whether she withheld consent, or concludes that the defendant reasonably believed she consented, it must acquit.
