I think in this case, since the obstacle seems to be in her concept of sex itself, it's probably not so much about taking her clothes off the 'right way' but managing her overall perception of you, her and what is going on.
Something I did with the above mentioned girl was that I handled her a lot and regularly pretty much as soon as we went in the door - kissing hungrily, gripping her hair, pulling her in and squeezing her butt, sliding my hands up under her top and down under the back of her panties (she swatted that one away, but I kept doing it every now and then and just smiled and looked her in the eye whenever she reacted), etc. When we were nearly at the point of having sex and she was down to the panties I'd regularly grab her pussy and rub her before she pulled away, smile and tell her she was wet and wanted to feel me inside etc. And this resistance was very hard for her to keep up because it took effort for her to overcome her own horniness and refuse a guy who obviously wanted nothing more than to fill her up.
She has to know first of all that you are a hungry dude and you want to fuck her and you aren't going to change this while she's there, she can leave if she wants but if she stays there's not going to be any disney bs. Otherwise she will think that there's an alternate reality she might be able to access in which somehow she stays in love with you while you two never bang. While the reality is that she's there exactly because you aren't the kind of guy who lets that happen
Then (if you want her enough and have patience) mix it in with other rapport building things, like the cooking, deep conversations (this girl I mentioned was very smart and loved talking about about random semi-scientific topics), a bit of cuddling, etc. But never stop showing her the werewolf, never let her forget who you are.
At the end of the day she has to really feel the pressure of your desires nearly to the point of not feeling in control, but then also that you're willing to show her another side of yourself as well that she can rationalize as being the reason why she ends up going ahead.
But you, you have to always stay cheerful and warm, showing desire and patience but never annoyance or anxiety, and if you've had enough, simply bring up that you are a dude who values sex in relationships or whatever, and if she's not down, move on before you end up messing up your own vibe. Sex shouldn't be that hard to accomplish if she wants it, and if she can't submit to her own desires, too bad for her, you're not her therapist.
