In my opinion, it could be a fake ad for the purpose of ripping somebody off. It just looks too good for the price of 160/hr. Don't most girls with big natural breasts charge at least 200-250 or more ? The low price and offer of low restrictions just gives the pimp a better chance of finding an unsuspecting victim. Be careful.
But whoever this girl is, she does have a nice pussy. The sad thing is, the pictures were more likely stolen.
