The Substance 3 by SirDominator
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 got him hard 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.
At the end of the day the Master opened the cage and commanded for me to follow on my knees. I crawled behind Him as we left the workroom down to His bedroom. The Master stood and commanded me to strip His clothes off of Him. I stood and removed his shirt laying it on the chair then his slippers and pants. The Master never wore much in the way of clothing. He looked me in the eye as a wave of pleasure rippled through the substance.
"Stand and bend over the bed slave" He commanded as I rushed to comply. I bent over exposing my ass with its device still inserted. The Master pulled it out slowly with a chant I could not understand. He then placed a blindfold over my eyes and secured my arms to a rope above my head. I shuddered in silence as He whispered "You are mine, your body belongs to me"
I felt his hand slap down on my bare cheeks back and forth warming my bottom as little ripples of pleasure were allowed from the substance. Then a moment when He stepped away and then a leather strap was applied to my ass back and forth as I screamed in pain from the burn of the strap. I could hear the Master growling in pleasure from striking my body. I begged for Him to stop as He continued to beat me.
Finally He stopped and my balls were squeezed firm by the substance. My cock hard from the whipping and stimulation of it. Unable to cum because of the constriction around me. I felt the Master press His thighs against the burn of my cheeks as His cock drove into my hole. I bit down on the covers as He fucked me hard taking what was His.
The Master kissed my neck as His body lay upon mine with His dick firmly rooted in me. His chest against my back as He ground His member inside me. The substance milking at my cock slow. Then He rises up and pulls His cock back driving my hips into the bed. His cock rubbing my prostate as I cum into the substrate. He starts to fuck me hard hands on my hips as I take His cock over and over. My cock getting hard again as the substance starts to work on me in time with His dominating force. Master chants a sex spell and His cock swells up bigger in my ass pounding me harder and faster. His magic flowing in and out of me as its expended and recycled though the conduit of His cock in my tight hole. "Take this Bitch, pound me Master" I screams as the pleasure/pain builds in the heat of sweat and sex. The Master growls and takes what is His in primal lust and magic til He explodes inside me.
He catches his breath lying on top of me kissing my neck. "You are a good fuck, slave. Lots of magic inside you for me to use. You may be my conduit for a long time, good bitch conduits are so hard to find." He pulls His cock out of me and lets it touch the substance. The substance cleans His cock taking the sperm from it and pulses around my cock letting me feel pleasure. The Master unties me and sends me to the slave quarters for the night with my ass dripping with His cum. As I go to leave I feel pain strike my balls and the Master comments "Thank me for the fuck, slave"
"Thank you Master for using this slave" I whisper in agony then gingerly walk down the hall back to the other slaves.
