I love taking away my subs senses one by one. Starting with their ability to move - restraining them in tight restrictive rubber. Gagging them, taking away their ability to speak, pushing a hood over their head muffling their hearing and then blindfolding them, taking away their ability to see.
As they are completely encased in rubber - with only the smallest pieces of flesh exposed for me to play with.
Just an object for Me to tease and torment them. Unable to escape as I attach electrode pads to their cock and start sending waves of electricity pulsing and shocking through them. E-stim shocking their cock. Tweaking all the knobs and buttons on my little box of tricks as I watch them start to moan and groan and squirm under the sensations I'm administering.
