Bro,
Actually this 3 hours, 1 shot for the Premier Models seem to be the market for these so-called high-end models. I know 3 hours is really a long time for 1 shot unless of course you have very strong mental strength or inability to ejaculate. Hehe. Unfortunately, these terms are imposed by these gals, so bo bien lor.
That is why most of our clients bring them out to eat, drink, show them off a bit, then go to the room to have their 5 minutes worth of fun. And you are right, some of these ladies, if they really find you good company or loaded, they may want to stay for longer but the catch is,they will probably rip you off by asking you to buy them drinks or go cheong which at the end will cost money also mah.
I guess at the end of the day, its about chemistry and the size of your wallet. Most of these ladies are not looking for love obviously.
Salamat Kuya!
