Most often, girl who is consenting for it will also be legitimately scared and suffering as just like you want to beat her for real she wants to be beaten for real but in the way she wants, at the level she wants, at the time she wants, and by the guy she wants. So better don't screw up how you serve her LOL
In the real life, to get that, girl will deliberately get into situation where she will be attacked and raped just later complain that she is an innocent victim.


But either way ,you seem to be not into beating or torturing girls but rather into pain/ fear emotions and probably some kind of hate sex.
I am more interested in the spectacle itself and it is even better if girl gets sexusly aroused from that as well fear and suffering is a turnoff to me in general
It is also great when girls is insane and has self destructive behavior which we all like so much.
It seems that this self destructive behavior is the sexiest most attractive thing for both men and women :)
