My prisoner was bound to the fetters chair with straps. He was locked in a tiny room and shut away until I was ready to deal with him. I placed estim pads onto his nether regions, and placed the nasty wire cock ring onto the centre of his cock. He had no choice but to endure the estim! I started the power on low and slowly ramped this up. He was fastened tight to the chair, but still was jolting about! I taunted him more with some nipple play (that was one of his soft limits). It was sheer enjoyment from me to push his pain barriers and boundaries!
