This guy is a simple
worker and he doesn't earn enough to buy his pretty girlfriend expensive gifts and stuff. He knows she wants those and he knows she wants to have sex with a total stranger, so he makes both of her wishes come true together. This rich guy is willing to pay some big bucks to fuck such a hot teeny and the money these perverts get for it will buy the slutty chick a new dress and maybe even some really high-class jewelry.
