Sicksadist69 Studio presents Gia Derza's brutal training session. She's a slave to his cock, taking it rough and deep in every hole. He makes her lick his feet, squirt on command, and drink her own piss. She's a whore, he tells her, and she believes it, moaning and begging for more. He slaps her ass, spits in her face, and humiliates her until she's a quivering, liquid-soaked mess, ready for anything.
