Sharena, I think it would be best if you practiced a couple of times just with Isis before you had a guy there too.
As you are semi-private now, and rent your own nice room at Sakura Palace I think you are on the right track in introducing new special services to raise interest from punters. You are already a unique girl of course, but when you go freelance you really do need to up the promotion. You have been doing that already, but you have to get creative about it, and a bi-double with Isis would get a lot of attention here for sure!
