Mistress Sidonia has some devious plans for her slave, she has him semi suspended from the beam block, harnessed tightly in a straitjacket, cock exposed to her whims. After teasing him to hardness, Sidonia attaches a heavy kettlebell to his cock and balls and commands him to drag it across the dungeon floor, stretching them out as he struggles with the weight. She then attaches a 20kg bell with multiple pegs and orders him to tug them off, using stronger ones if he is successful.
