If it is the group of ladies I think it is, it is not B&S but there is an upsell involved. The language of the ad suggests to me that it is the same group of ladies based in California notwithstanding the area code of her cell. $250 is just for a HR and it is another $100 to get her topless and another $200 for her to get nude. This is a sort of high roller massage agency that has been operating for years (they have had some major hotties as well) but they do upsell if it is who I think it is.
The language of the ad sounds identical to other ladies I have seen from this group of travelling MPs. In past years the girls they had included Mary, Beth and there was previously another Bridget who was different than this girl but equally hot. Unless you are willing to be upsold I would suggest looking elsewhere, but if it is the same group it probably is the girl in the pic. They deliver high quality girls, you just have to pay a lot for them.
