Without the illusion of control over him, and even she has to know it always was an illusion, Claudia realizes he could not only undo her in every possible way, but make her beg for it. That's what he's proving to her. And she can't even find it in herself to deny that's what she wants.

Without an orgasm to prepare the way, he has to keep pushing in, small spasms squeezing him, but she remains tight and wet, and with the images in her mind, she stops trying to hold in her moans and screams and whimpers, letting him hear how much she just wants.
