I like my sisters best friend?

Ok so I like my sisters best friend and my sister knows it. And she thinks we would be a good fit but she’s really hard to read what are some things my sister could ask her while being discreet about it because I don’t want to make things awkward between them if she doesn’t like me like that

Ya I hope she does though I’ve had thoughts of dating her for months now but I’ve just been way to scared to even admit to anyone about it but I’ve gotten to the point where I just can’t keep it a secret anymore and the only person I’ve told is my sister and that was 2 days ago
