The only girl I have found that give a real Japan Hotel Health Club type service is Ayumi, 3267. Posts on ERS. Typical service will start with nice massage, with towel. She will, be naked and has lovely breaststroke. You will get a talent cocktail and ball Massage where she is gift at bringing you to the edge repeatedly. In the mix will be bbbj and Russian and body slide, all done with a sensual tenderness which is the highlight of true Japanese service. The highlight will come when she mounts you and rubs her vulva up and down your shaft. In Japan that is all you are going to get, they can make you come like that. Ayumi is all you can get in Japan plus more because now you can let the fucking begin. I've done every position imaginable with my personal favorites cowgirl with nice handfuls hanging down or missionary staring into the lovely eyes.
Give her a try and let me know how authentic you think the experience is.
