Is she trying to goad him into losing his temper with her, so he'll grab her
by the throat, smack her around, throw her on the floor, rip her clothes,
pin her down and violently fuck the shit out of her?

she keeps putting down Shinji's masculinity and flaunting her own body to
him at the same time. I think that she secretly wants Shinji to snap, grow a
backbone, pounce on her and give her the rough fucking that she wouldn't get
any other way (Kaji is such a fucking fag. She was nearly fucking his leg
once and he still refused to screw her).
