I want to ask my coworker out

I made a bet with a coworker I was riding with that I could ask her out and he said you don't have the balls and it was over 2 slushies double or nothing so like 4 bucks. So I was supposed to say we only have 5 years left to live because an asteroid is going to hit earth do you want to go out with me "her name". I did it and she turned red huge smile eye contact and laughing and then she moved out of my line of sight and she snuck out of work knowing I wanted to talk to her after she had to shit. because it was mostly a joke because he was there too. So I won but I'm wondering if he wasn't there maybe she would have said yes because she didn't say no. Sometimes we're just looking into each others eyes. A lot of teasing and we do talk and can hold conversation. And a lot of sexual enuendos. She literally took a pen and drew on my eyebrows holding my face. I'm afraid and I want to tell her she is beautiful and that she makes me laugh. But I don't think I'm at her level. I'm thinking about waiting till the last week of work so I can just quit if I have too. My biggest concern is getting fired because in my line of work, workplace dating isn't really allowed unless it's different shifts and can't ride together.
