It's not rape. Your interpretations of the scenes are simply your interpretations and misreadings, they are not factually correct. The human npcs want to have sex: they are not rejecting, they're not saying no, they're not begging for it to stop, their actions and dialogue support the idea that they are consenting and that they want it. I said it's consensual and their actions support that it is consensual and there is nothing the characters say that goes against the idea that it is consensual. The officer literally says: “Help me get these clothes off!” That is not the hitchhiker telling you to rip the officer's clothes off, that is the officer himself/herself telling you. It should be obvious the officer wants to have sex and is consenting.
