Hanging upside down on the inverted slab, Mistress Vixen's slave is helpless and vulnerable to her sadistic desires. She uses the fucking machine on his exposed arse, the huge dildo filling his hole, the relentless piston making him moan as Vixen torments his nipples at the same time. She then attaches electric pads to his cock, enjoying the slave's reaction as she turn the power higher and higher.
