I reached down with my hand to try to get the substance off of my cock and balls. The pain as it tightened further onto my sex making me cry out. I tried to rid myself of it in many ways. When we would shower I would try to scrub it off but it would only cause pain if I touched it with my hands. I tried to rub it off onto something hard but it would not budge. Pain would come every time this mage blighted stuff would sense a threat to its hold on me.
The Master walked in and laughed at me in the cage. Occasionally he would chant some words and the substance would start to pleasure me getting me hard and the device in my ass would pulse. Pain would come mixed with pleasure as He tormented me.
"You are my bitch and plaything. Your only purpose is to serve me and my needs." The Master would stand around as He practiced his sex magic. Once in a while another slave would enter and leave food for me and the Master. The substance was on all our cocks controlling us. Once the Master looked at the other male and chanted.
"Thank You Master" the slave would be hard in his substance as it stimulated his member and forced him to cum. Magic flowed from the slave to the Master almost visible to the human eyes as the substance devoured the cum.
