answer:Since you’ve never actually met these women before, my suggestion is to simply treat it like the four of you are hanging out like friends. So friends rules apply. No overt touching or closeness. Flirting, if any, should be light and casual… and not certainly sexual. Pay dutch. Et cetera. Feel out the chemistry during this introductory period… and at the end of this get-together, decide if you want to ask your counterpart out on a real date. And if you think you that you do want to, then ask her out sooner rather than later (ideally just before you part ways at the end of this meet)... don’t leave her hanging out there wondering if she made a good impression or not.
