So, what is your end goal?? End to the loneliness?? Girlfriend?? Free sex?? A wild and bumpy ride?? Not a wife and kids, of course....
I don't know the details of her situation, but I would guess she NEEDS to work as much as possible - pay off a debt, or drugs, or gambling, or etc so she will not be available often or for very long. Somewhat captive to her spa, most likely. So still some loneliness. Her "vacations" from work may coincide with her periods, so that complicates the free sex. Also, after a couple of weeks of getting pounded for 12-16 hours a day, spending the weekend getting pounded by your huge cock may not be super high on her priority list.
You are going to spend quite a bit of time (alone) texting her between clients til mamasan comes in yelling and she has to tell you goodbye so she can suck and fuck some dude. Job/money (and that dude) cum way before you. You then have a lonely hour or two or three or more, waiting for her to shower off the cum so she can text you. And repeat.
You want advice?? See her as a provider, text her as your "relationship", continue to be a nice guy (let HER dream about a relationship with you), and let her ONLY be a placeholder til your next real girlfriend. Oh, and try not to think that there may be two or three or four guys just like you doing the exact same things with her...........or the hundreds of dicks going in and out of her and cumming in and on her, over the weeks you don't see her. Let her have the feelings, you just need to be super nice and "make love" to her. Don't read her reviews, either. Best of luck..
