The more I experiment with my slave, the more I dream of rubberized and bound cock and balls. Good thing I put my slave into tight rubber and strict bondage over the night, so when I wake up all horny and aggressive in the middle of the night I can just go over to his cell and use him every way I want. I put on some very thick and bizarre latex gloves. I first start to stroke his dick in a black cock and ball sheath. When I pull it off to reveal his dick and balls already tightly bound with black tape, which has kept him hard throughout the night.
Lubing him up with lots of oil, I pull his balls hard and make him cum all over the shiny black rubber. Now I can just leave him there and go to bed, playing with myself all aroused by his pain and humiliation.
