I have been punting Asian escorts since 2007 in London, I have come across 2 Japanese and 2 South Korean women, There was once a famous seriously horny Japanese lady who had 2 or 3 stints in London 7 - 8 years ago but her name has escaped me. (she used to work independently on AW) If anyone remembers please help jog my memory. The other Japanese girl I remember was also very horny this was back in 2009 working out of Chelsea but was only around for a couple of months. The 2 korean girls were very disappointing in terms of service although they were hot.
Not saying impossible, but just very, very rare. Could also be a mixed girl with a dual passport. But seriously, girls can earn so much more in Tokyo than here and they rarely have to do full service (they do nuru, 69, sumata, hj/bj but rarely intercourse as it's illegal). Also most Asian men have small cocks and come quickly (I've been told by many a girl) so it's easy money. There is a reason why modelesque asian girls are expensive/no foreigner, it's because we are the barbarians who want to do hard core stuff (even OWO/CIM is off the cards most times). Get paid £150 for some brute to mess up my make up? No thank you. Pay in Tokyo is something like 30,000Y an hour (about £230), if you were a mixed girl OMG you could earn double that. So it just doesn't add up to work here unless you have no other option. I have seen some supposedly Japanese girls on some high end escort sites for £600+, That makes more sense as they would be a rarity. But hawking on a lame design website or on AW for £150 an hour, no way!, and if she was, she would disappear quickly into some agency quicker than you could say sayonara gaijinsan!
And I agree, Korean girls are so hot, but very inexperienced (kind of what makes them hot but...). I picked up a couple of K girls a few years ago and, well, that's another thread.
Taiwanese girls, also hot. Mannerisms are very similar to Japanese. Kind of Japanese/Chinese hybrid (so f'in hot)
