Bound and vulnerable, the slutty slave's asshole clenches in anticipation. Mistress, her sadistic side aroused, prods his hole with her massive strap-on, making him gasp. She spits on his ass, lubing up before slowly pushing in, inch by inch. His cries fill the room as she picks up speed, fucking him raw, owning his ass, leaving him a panting, used, and grateful wreck.
