Japanese Karina is roughly 25 years old, 5'3 slender frame, small breasts small ass. Very unique looking face, almost looks mixed with white. She is a good find, fun full menu. I would say if your into young skinny submissive girls give her a shot.
Then you have the new addition Japanese Kanna. 23 years old, 5'1 roughly and a little larger body (not fat). Maybe C cup boobs and a bit of meat on the ass. She has an aquatic/athletic background before coming to Canada so has a fair amount of musculature. Very passionate dfk, great bbbj. Beyond that YMMV as I don't think she is looking to have sex at the spa, but you never know.
Both girls are fairly quiet, both you can take the lead in the session if that is your thing.
I have to say, I've been to many many spas and seen many girls, OM seems to attract the youngest, prettiest girls outside of Incall agencies these days. Keep up the good work Yuki!
