Most insulting verbal abuse of the victim?
 

What are the lines you think are the most degradating during fantasy rape? To me: first- during forced blowjob rapist says-'you are ugly. Too ugly to even be raped' or second one- after he raped her ass he says:'there is worse smell than horseshit, because of your ass. Lick my dick clean dirty whore'

heh, that second one gets worse when he actually makes her do it.
the first while emotionally cruel feels counterproductive since why would he rape her if she's ugly? nah, i think it's better when they say she's a dirty whore and things like that. that she's a slut and she likes being raped and wants to be raped because of how she dresses or moves.

I think that telling her she's a whore and a slut for doing what you're forcing her to do always seems like a cruel and exciting way to spice up a rape. I love the idea of making a girl tell me what a whore she is, and call herself a dirty cunt, and say how much she loves sucking cock and whatnot. Would be really 'extra' humiliating for her lol :-)

Two words
 

"you're wet"

Yep. that's it.
The implication that some part of her wants it is the "worst"

Well, actually that makes me too horny to feel humiliated...!
I am searching for something that would not make me more wet after I hear it during our rapeplay, but rather embarassed, more shy, with red face... and I cannot. I just feel good about being called a dirty cunt...
But, as I am very smart and ambitious, last time I asked my Master to degrade me by saying that I am too stupid as a female and worth only to be fucked. It should work.

Was your pussy really worth this struggle?

from the movie 'Irreversible' : "ha your ass is so tight, your boyfriend must be a fucking fagot"

Toilet princess.

Make sure she comes and say "See, I knew you'd like it. I knew you were just a perverted, dirty little cunt. All that crying and fighting, and all the time you really wanted it."

"You deserve this!" - especially when the rapist makes me believe his words by making me orgasm after I fought him tooth and nail for the longest time.
Followed by a cruel "See, you were made to be fucked like this", when he pulls out and gets dressed while his sperm is leaking out of me, no matter how hard I try to press my sticky thighs together.

Rape victims should be required to wear a t-shirt with "I was asking for it" printed on it.

In my experience of introducing new female play mates with no previous experience to role play i'm often very surprised at just how much they thrive then crave the most sordid verbal humiliation, especially insults around just how pig ugly they are even if they are plain Jayne's or lookers.

see, this is why I always keep duct tape handy. So I can tape your ankles together and then bind them high to something. Then no messy leakage, or well not much anyway. See ain't I considerate?

BTW

"I knew that's what you neede" right after I slowly pull out so as to minimize the leakage followed by "no need to thank me, I'm sure there is a little something in your purse, don't worry I'll check"

I don't really talk to them, I want them to insult themselves. A knife at the throat and they would be willing to say things like, "my filthy cunt isn't worthy of this, you honor me."

I think telling a victim she is "doing a good job" while blowing your cock would be a good way to insult her, let her know she is giving you pleasure even though she hates it.
Think about it. She is unwillingly sucking your cock and you tell her she is good at it. Or when doing her ass you tell her how tight and hot it is for you.
