Ya, I've tried Oshi before. She is quite good looking, and has a smokin hot little body. I thought her technique was pretty good, but was definitely not impressed with her customer service. She booked me in for a half hour and had someone else scheduled to come in before my time was up, I was afraid her next client was going to get there before I was gone. After about a 3 minute massage, she went straight to the extras, just to get me finished up and out the door. Meanwhile she answered the phone a couple times while she was with me. So ya, I wasn't overly impressed.
Despite that, I think I may go back some day, I'd definitely like to see her naked some day if it doesn't cost too much.
