TL;DR: they see me as their gay friend, what should I do

I'm pretty sure this happens with a lot of other guys as well.

I'm 21M, normal-good looking, really friendly and extrovert. I'm not scared to talk with girls, but the problem is that I'm too friendly, when I should have a more "alpha attitude" sometimes.I met a girl who's sister from my friend, she's 29 but hangs with our crew sometimes, she fits nice with us. She and I have great and fun times together and

I'm pretty sure that I already had a chance to kiss her, but why I didn't? Don't know, we were both drunk, laughing, night time, we weren't alone though, her brother don't likes the idea of his friend kissing hir sister but fuck it.

Anyways, she drove me home last Sunday by 5pm after a party, we weren't drunk anymore, just having a really good and friendly talk at her car, I'm pretty good at having nice talks with girls, actually too nice, I'm sure I should had switched the subject of the talk to something more spicy, but I wasn't sure if she would follow me up on that moment, so I didn't try it, cause I suck on making moves when I'm not 100% sure.

I had a reason to talk to her by messenger the next day (because of a joke we made before we said goodbye), so blablabla I told her that a knew some really pretty and cool bars that we should hang in. She said "whenever you want!". We will probably see each other some Saturday before I call her to go out (hanging with our mutual friends), but that's not the point, the point is, when I'll go out with her

What should I do, I know I have to make more aggressive moves cause right now I'm just a really good person/friend to her and I'm scared to step into the friendzone, IF I'm not already on it, but how, I mean, do I have to keep being myself and hope for the best, or not being so friendly and exposing my real intentions with her?

Yes, I want to be her friend too, but I don't need more friends, I need pussy.

(I'm not the kind of beta-male, I live alone, pay my bills, work, study, go to festivals, travel around the world (alone), lots of stories to tell, blablabla)

Sorry for giving so many details, I just wanted to get more specific here.

Maybe I need a good shake of life to fucking wake up and f*ck her right in the pussy.
