Rey and Poe now share the experience of having their mind invaded by Kylo and the loss of control is fucking with them. They roleplay noncon with each other (for the feeling of actually being in control while pretending not to be, and/or for pretending to be in control) as a means of processing that. I'd prefer that it not always go so smoothly - someone goes too far, the person playing the aggressor doesn't realize that they're allowed to have problems with this too, all the usual sorts of things that can go messy or wrong in rape roleplay.
