Gagged and bound, the slave is a squirming mass of need, their body covered in a sheen of sweat. Hardcore-Buff18 watches, amused, as the slave's eyes dart between her pussy and the strap-on cock she wields. She moves closer, pressing the head of the cock against the slave's lips. They open, eager, and she pushes in, fucking their mouth hard. The slave gags, their eyes watering, but they don't pull away. The mistress pulls out, leaving the slave gasping, before turning them around and slapping their ass, leaving a red handprint. "You need more, don't you, slave?" she purrs, pressing her pussy against their face. The slave moans, their tongue seeking out her clit, desperate for more punishment and pleasure.
