A new slave's first day of throat training begins with a face-fucking from Mistress Maribel. Her meaty cock fills the slave's tiny mouth, hitting the back of her throat. The slave's eyes widen in panic, her gag reflex kicking in, but Mistress just slaps her face and thrusts harder. "Take it, slut," she growls. The slave tries to breathe through her nose, tears streaming down her face as she's thoroughly used, her throat stretched and abused in the most delicious way.
