safe words??

Well, the main female character and the guy (don't remember names, but the guy that she cheated on her ex-boyfriend with) are both technically rapist. They both technically raped her ex-bf (he almost did, but kinda did, and she 100% did, like, the guy was shaking... He might not be the best person ever but I don't think that he deserves to be raped. No one does...), and the guy told her that they can do whatever they want (which is kinda too much considering that the brown haired guy didn't technically approve to it), so I don't think they even care about safe words which is.. Yeah...
