This demon seems to not care what's even happening with him, he's smiling through the whole thing..so apparently to Finn it's rape but to the Demon it's not because he was using it as a plan all along to show the true colors of these people plus he has like no trauma he just shrugs it off as if it didn't happen he is a demon he isn't bound to human physics, he pretended to be weak and vulnerable to so Finn can snap which the plan did work.
