The exchange is explicit, the terms clear. For every thrust of the benefactor's thick cock, the girls earn a crisp bill. They kneel before him, taking turns licking and sucking his shaft, their saliva dripping onto the expensive carpet. He fucks them missionary, then flips them onto all fours, his hands gripping their hips as he pounds into their tight pussies. The girls, their bodies glistening with sweat and juices, beg for more, their voices throaty with lust. The benefactor obliges, his cock never softening, his hunger for their bodies insatiable. When the last girl collapses, spent and satisfied, he counts out the final payment, his eyes gleaming with satisfaction.
