So my aunt fiance has two girl cousins, been introduced to them and wasn't really a pua artist back then. I have a little experience now and want to really get to know them, the only thing is that I haven't seen them for like 1+years now. . . wouldn't it be awkward asking my aunt to tell my uncle if I can hangout with them and get to know them?

Hey
It would be wrong by asking to meet them since then it would bring the wrong situation. It could easily be awkward. Is there any situations where you would meet them naturally like a wedding or something? You could open one of the girls directly by saying it has been a long time since you last saw each other and suggest to go clubbing with them. The thing is that a normal meeting in lets say a dinner with your aunt and fiancé would be ugly. If you get them on the town with you, you have a huge atvatage since you'll come to the club with 2 girls and have instant qualification.

Hope it helps

It really helped a lot, thank you.
