Doubt you will get a real Jgirl. One way to tell - if she is short, has bad teeth, small palms (hands) and her ears stick out too far from the side of her head, she is authentic Japanese.
In Japan, soapland girls are amazingly talented. I had one girl service me and then when she refused my request half way through the appt, she gave me a full refund. I basically got 15 minutes of fun for free.
Holy Shit.
