I'm attracted to my best friend's sister. What should I do?

My best friend's sister is a beautiful girl who I consider are someone who I. We have had a lot of interaction and know a lot about each other obviously through her brother (my best friend) aa well. We both know each other's family too again because of my friendship with her brother since childhood. I just don't think my friend will take it well and I'm afraid our friendship will be finished. I just don't know what to do. Tell him? Just keep quite for the sake of my friendship? His sister also likes me and is not sure about this situation. she's my age and my best friend is 2 years younger.

Im confident that won't happen. Me and her have honest intentions. Its a big step for us and we want all the whole family to know it. Im sure that implies that we are serious about each other.
