Harmony Rose and Aiden Starr are two tough bitches who know how to give punishment and pleasure in the perfect balance. Their new recruit, Sarah Shevon, is taken to the brink of her limits in every scene. She is made to grip an electrified shovel handle that painfully shocks her hands causing her to dump the dirt and receive a flogging from the Mistress Aiden. Failure after failure has Sarah face down in the dirt pile while Harmony teases her with the vibrator and Aiden dishes out the pain. The two Doms do not let up as they fuck all Sarah holes with electricity, teach her how to lick pussy and ass and work Sarah into a thankful mess. Once Sarah gets better at pleasing - they toss her down and fist her until she cums.
