Ironically, one of the ways you can tell if they really like you is if they engage in DFK. In their culture, DFK is considered more intimate and meaningful than intercourse. Kind of ass backwards from Western girls, but makes sense in a way. The mouth is closer to the brain than the pussy.
This, 100%. I posted earlier in this topic mit my old handle before the bangasm about having a provider who I was thinking about GFE with. Many sent great advice and I enjoyed and appreciated, set me in a way that I can manage this.
Since then, it has escalated, but to exactly where I'm comfortable.
The kissing thing was it. I told her more than two weeks after she DFK that it was a super turnon, and she blushed in a way that I never saw from her. She explained as you did, that for them, this is not a thing to happen casually, DFK is only for special. I have seen same in many providers over the years, and two Chinese gents who work for me gave me an odd look that it even happened then confirmed that it was not something to take lightly.
As others said, "let her like you more than you like her", and that was slam dunk great advice. For me, I don't want or need a girlfriend. Am married, and every AMP I go to they want the BFE and be texting all hours of the day and night. But the worst for me so far is that they fscking work 12 hours a day, you know, the hours when I'm at my plant running the business. So it's not practical in any setting other than their store. This one texts me the moment she gets in her car to leave the store, but by that time I'm already in my bed, am not going to get dressed and drive 30 minutes to go lick lick lick, although of course I'm tempted.
That she likes you more than you like her thing, wow that did it. Is like old thing girls used to do when I was small, playing hard to get. Now, she texts me dirty pictures and is leaving her store, i.e. leaving potential money on the table, just to take me out on a date to a place I told her I might like to go. Is kind of a role-reversal to how I would normally be, and it's awesome. If I don't text her within say two hours of her text, she sends me a nude. Who wouldn't want this lol
So, keep it real mongers, if she wants the BFE, why not give it to her, but make her want it so bad that she begs! It's kind of awesome. But still remember, when she's not with you, she's jerking dudes off for money. And as others mentioned, it's not unlikely that they always will.
