Slaves need to be trained for strength and endurance and Dometria invits her friend the Muscle Mistress to lend a hand with her special talents. Dometria gags and stretches her slave hyelplessly on the pulley before moving behind the camera to watch the Muscle Mistress brutalise the boy’s cock and balls. The awesomely powerful Amazon goddess wastes no time and flogs his cock and loads up his balls with an agonizing forest of clothespins digging deep into his scrotum and cockshaft. Then she hammers them around with a leather flogger and steel crop. His bollocks are now just a juddering target practice for pain as she beats them till the red stuff stains the wooden pegs. Mistress Muscle is learning fast how to be cruel to men and she just loves smashing up the guy’s genitals.
