Be condescending

I felt an irrational surge of anger as I saw how pathetic she looked.

"Yeah," I said. "It is, but we're not going to stop are we?" She looked down as I said it.

"We're going to continue spreading our legs and let those assholes fuck us, because we care more about cock than our fucking self respect." She was blushing now, but I didn't stop. "You're going to keep acting like a cute innocent for Todd aren't you? Even as you let Andrew turn you into a bigger and bigger slut. And now you want me to tell you that it's fine for you to act like a whore? I don't like what we're doing any more than you do, but I'm not going to fucking rationalize it for you!"

She had tears in her eyes now, but at the moment I didn't care.
