No micro is going to accommodate such a request. They're not there to sell companionship, just fucking. And the more you go around asking with such an usual request, it's only going to raise red flags for them. Your only way to go about this is to see these girls for a session and if there is some chemistry and/or you offer them enough money to consider going out with you when they're off the clock. Not an easy task considering the language barrier, especially with the kgirls.
Tant and hypes has the right idea - it all comes down to chemistry and comfort. It goes beyond the almighty dollar with micro girls sometimes as most such "dates" don't even come with a price tag, they're usually free (until you have to pay for dinner, that is).
