Candy Girls was a collection of amateur sites run by a company called "Candy Girl Cash". These girls included Busty Robyn, Rosie Jaye, Tegan Brady, Dors Feline, and other models from the UK. IN most cases, the girls were shot huge amounts of content sets in a very short period of time, and then were no longer part of the sites. This sort of "paid off amateur" content was very common, as it was a way for a site operator to assure they could run the site with or without the girl's participation.
The sites ran from about 2008 to about 2014, and then slowly dropped off. Some of the domains have been snapped up by malware installers.
