Having been to Yokosuka once the only thing I know of are Chinese streetwalkers. However, some research suggests delivery health somewhat exists. You may want to try Yokohama services since it's the nearest major city.
I tried them before but when I wanted to try them again they wanted to send me the same lady. Communicating with them was a bit difficult. I had Kazuki by the way. She was not very attractive and her body was terrible.
thanks for the info kazuki pics dont look so bad. was she at least a good hump cum machine? this group has a lot of old ones add 10-20 lbs and 10 years for sure. ill give them a try and make a report.
