That is a pretty good review, you beat me to it. What,s funny is I may have been the guy waiting on you and depriving you of that hour. Have been lurking this site for many years, more off than on as I am an ex Shangri-la go to, primarily because of Lucy. Like you, she wanted me to try the new girl and booked an hour.
Cecelia saw me come in and said, Lucy huh? I laughed and did not reply. She had appointments because she was not scheduled to be in.
Bianca, as OP said is thin but I thought was very pretty and very young, don't know what that girl from the other spa looks like, never been to there. Said she had pro training in China and does very well here as an esthetician. Her massage is excellent using hitting those knots much like Jennifer, glad I took the hour, the last 15 was all tease and HE which I would consider one of the best out there. Over the clothes touching, no body slide and if you want nude, would be like having a membership at the Royal Ashburn Golf Club, you want it, you pay. Didn't mind paying to see her and as OP said, all natural small cup but one the nicest asses, shapely and toned.
So let's say if you want an upscale massage with an amazing HE, she is your gal at regular prices. If you want nude with dry kissing her ass, no tongue, expect to pay extra, extra.
Bianca is a class above the rest and will do well.
