I want to go on a date with my sister.

I'll start by saying that I'm a 24-year-old guy and my sister is 22. We've always gotten along well, and I've always thought she was hot as well. But, I also recognize that we're siblings, and a relationship like that is frowned upon in most areas, so I've tried to keep my thoughts in check, and I understand if you don't feel the way that I do. I don't want to force her to do anything that she doesn't want to do, and I don't want to try to be pushy or gross in anyway, I just want to see if she feels the same way that I do. So, I want to take her out for a drink (some alcoholic beverage), with the intention of asking her to be my girlfriend. I want to know if she would be interested in that at all, because I can't see myself with anyone else. So, my question is: What do I do? I'm obviously biased here, so I'm not sure if what I'm thinking is rational, and I don't want to hurt our relationship. I don't want to ruin anything, and so obviously, I need outside help with what to do. <br><br>TL;DR I want to go on a date with my sister, but I don't know how to proceed, or if I should at all. I don't want to hurt her or our relationship.
