Sensitivity Experiment

Mistress Lady Renee is exceptionally adept at finding and pushing her slaves limits, however this slave is unknown to her before today, so he must undergo a thorough and painful examination. She starts by stretching out his nipples and cock, before dripping hot wax over his most sensitive parts. What starts out as a quiet and determined slave, soon becomes a quivering moaning mess before her... just how Mistress Lady Renee likes her slaves!
