The dominant mistress, her eyes gleaming with sadistic pleasure, commands her sub to assume the position. She lubes up the monster-sized, red anal plug, pressing it firmly against his quivering asshole. With a confident grip, she pushes the toy into his tight hole, inch by inch, watching as his ass gapes around the thick shaft. She fucks him hard with the plug, her pussy throbbing with desire as she hears his cries of pleasure and pain.
