I would recommend Rika 8308 and Suki 5890 but they are both gone
Summer 0753 is also hot IMO. I wouldn't complain her attitude and service are really bad, but compared to Rika and Suki, she is not better. At least Summer is still working, so what you care about is attractiveness only, I would recommend Summer as long as you don't care about a face with a plastic surgery.
