Fetish modeling has its advantages: It pays, penetration isn't required, it's so niche that no one founds out, and the models can choose what scene they'll do based on their substance preference. The models are just playing a filthy character.
... But not Peyton... Peyton chose a scene where she slathered her entire body in the thickest, smoothest, and totally dehumanizing black grease. Then, as the dirtiest whore of all time, she lets a man throat fuck her as she gargles his cock. Finally, she gets fucked doggy like a filthy animal. Still more, she moans in utter ecstacy as she creams on the cock treating her like a disgusting fuck doll.
Peyton might do it for the money... might. But any viewer knows that really she does it for the love of the game.
