Dr. Aspen Brooks has been working tirelessly to secure a patent for a new device meant to prevent live burial. But how is she to succeed if no one will let her test her theories and contraptions? Fed up with amateur assistants who won’t let her push the envelope, or their pain tolerance, Dr. Brooks hires a real professional named Dillon Diaz. Dillon is far more interested, suspiciously so, in helping Dr. Brooks than her previous hires. She gets her muscular assistant naked and bound on his back. His arms are raised perpendicular with his wrists locked in a wooden stockade. She cuffs Dillon’s ankles, applies nipple clamps, and sticks his head into an isolation box for good measure. All this makes his dick rock hard and so she turns it up. She grabs her leather crop and crops his legs and feet. She grabs his hard cock and strokes it as she crops his body. In the next scene Aspen’s legs are spread with her big beautiful tits out. Dillon nuzzles his face against her silk panties and it gets her cock rock hard. Dillon frees her big dick and sucks it down his throat, getting it wet and ready for his ass. Aspen has him get on his knees and she sinks her thick throbbing cock into his meaty ass. She fucks him hard and raw until they both cum massive loads.
