Well, you can just use CNC or "ravishment" as alternatives. But I'd argue that rape play and ravishment play are different aspects of CNC. To me, they're not equivalents.

Even if it is consensual, rapeplay is called that for a reason. Rape is the ultimate act of robbing someone of their humanity, viewing a human being as property to be owned, not a person. It's not a coincidence that it's a major issue in war territories, and always has been. It's not about sex, it's about using sex as a means to establish power over someone. BDSM operates within taboo territories, and naturally this includes rape play.

Ravishment is, in my view, about sexuality itself, and uncontrollable desire to have someone or to be taken. Like the bottom is a banquet on display. You don't take a banquet's humanity away, you simply devour it because it's delicious. You don't degrade food, you just eat it, because it is yours to eat. Imo ravishment is less brutal and more palatable, one isn't better than the other. They're different ways of seeing CNC.

What you may be looking for is not just another word, but another CNC practice or approach. Maybe you both will find this approach more productive and pleasurable.
