I have been there a few times over the past two months. I saw Tiffany each time. She is pretty attractive. Probably around 35 with small but supple breasts. There is also Aiwa who I have seen there and is reviewed here. She is a little older and has larger, augmented breasts.
In my experience, it is just a rub-n-tug. TIffany will beat around the bush towards the end. She basically expects you to remove the towel and make the intiation.
Best of luck...
