The ad for Eva on Eros is definitely a B&S. The picture used is one of Dena Doster, model and multiple winner of the Ocean City MD "Best Body On The Beach" contest.

Sure would be nice if it were real, she's a real looker. Anyone notice how the new picture layout on Eros list the image's by number's, not by name and location as it did in the past? That definitely eliminate's one way of checking the legitimacy of the provider.

...from the info on the "Dena Doster" site, she's got a hookerific profile.
