Just google it. Girls are 90% close to the picture. I am a westerner and was able to get the service because I speak Japanese fluently so you need to speak Japanese. The best so far I've tried. I was lucky to get sex as well for 18,000. It all depends the girl you choose and if you get along . For me is a 10.
