Still on his back in the cage that had been his home for the last few days the young man moved his head from side to side attempting to acquire some clue as to what might be happening in the world outside his cage. For several hours at least the house was dead, no movement or sound. Finally a sound! Was it the front door? He heard the sound of metal banging against metal, several letters settled heavily on the floor in the hallway. The young man struggled once more, moving his hips and thrusting his groin upwards. He could feel something heavy and hard around his penis and balls. He wondered what this was; he didn’t remember that being there. As his penis began to get hard from the mystery of what was down their he could feel the base of his penis getting tighter, was is a cock ring? As the blood swelled inside his penis he began to feel sharp spikes sticking into the base of his penis. Like needles piercing his skin the spikes dug deeper and deeper into his penis, the pain was excruciating, but as the skin around his penis was slowly broken by the spikes and a trickle of blood ran down his groin his erection only get harder and harder. This was a cruel trick to play, probably a belated punishment for some unsatisfactory act the night before. Struggling against the restraints trying to move his groin to masturbate, it would be a shame to waste such a glorious sensation. Little movement could be achieved he was securely held down. A stream of pre-cum ran from the head of his penis, down the shaft to the base where the spikes were sticking into his skin. The bleeding had stopped soon after it first began but the pain persisted. A grown and a sigh later and all movement inside the cage halted as the young man gave up on his erection and all hope of an early orgasm.

A few hours had passed and not only was the young man extremely horny but he was desperate for a drink. As he contemplated a nice cold glass of water the sound of someone making their way up the stairs made its way into the small dark room. The door to the dark room slowly opened and in walked Luke, tall and very muscular with short dark hair. He wore nothing but a pair of very loose black skate shorts that hugged every contour of his beautiful toned body and a key hanging from a fine chain around his nick. “Now then Pup, I bet your dieing for a drink?” Luke could see his Pup lying helpless in the cold steel cage. The young Pup was so thirsty, his mouth and throat was dry and sore. From behind his back Luke produced a large dog bowl, over the top of the shiny metallic bowl spilled cool fresh water. Pup pricked up his ears and struggled against his restrains, Luke placed the fresh water bowl right next to the Pup’s head. Pup strained and struggled to reach the bowl but unable to reach he started to whimper. Luke smiled and tipping his head to the side slightly, “I guess I’d better release you so you can enjoy your drink.” Luke knelt down and removed the key from around his neck. After opening the cage he stroked Pup’s bloody penis, he carefully removed the spiked cock ring, then the restraints around Pups ankles were removed, stretching his legs felt good. As the restraints holding his arms to the side of the cage were removed Pup slowly rolled over, his body aching from not moving. Pup looked down at the deeply inviting bowl of water then looked up at Luke. Pups master smiled at his pup and nodded his head. Pup plunged his head into the bowl of water and began to gulp down the cool liquid, but as soon as he had taken the first mouthful he pulled back in disgust. As the salty liquid made its way down Pups throat to his stomach and made him gag. “Something wrong Pup? That’s the only water you’re going to get, if your thirsty you better drink it.” Pup began to whimper again, it was defiantly not water. Memories of the night before and copious amounts of GHB came flooding back. Luke just smiled at his poor thirsty Pup and quietly he said rather menacingly, “Drink it”.

Pup once more lowered his head to the bowl Luke had presented to him. Slowly he gulped down mouthful after mouthful of the salty water. The GHB making him gag and retch each time, Pup lay back down on his back after consuming almost half of the GHB. Beneath the black rubber vest Luke could see the outline of his Pup’s perfect abs, he reached into the cage and pulled up the thick black rubber, after a little struggle he pealed off the layer of rubber from his young pup, sweat ran down from his chest down the groove in between his stomach muscles. Luke bent down and licked the sweat from his stomach, it tickled and pup clenched his abs even tighter making him sit up sharply. As he sat up the room blurred and swirled around him, the GHB was kicking in. Pup giggled and fell back to the bottom of the cage, Luke once more licked his pups stomach then suddenly without warning bit down hard and fast on his pup’s smooth skin. Harder and harder Luke clenched his teeth together, Pup crying out in pain. From the corner of Luke’s mouth ran a warm red trickle of blood. Luke released his hold on his pup leaving deep teeth imprints in his pups beautiful skin. As Pup saw his master lick the blood from his lips he let out a loud bark. Luke could see Pup’s rock hard cock twitching happily with beads of crystal pre-cum oozing from its perfect head.

The pup barked happily, the pain from his bite slowly subsided as the copious amount of GHB he had consumed quickly entered his blood stream. Luke reached to the side of the cage and attached a leach to his pup’s collar, wiping away some dry cum from the name tag that hung from the front of the collar Luke revealed the name of his newest pet. “Come on Spike, come on boy.” Spike stumbled to all fours and swaying from side to side followed his master. Luke led his pup Spike from the dark room where he had spent the night into another dark room. The walls were dark with camouflage netting hanging from them, in the centre of the room suspended from the ceiling was a magnificent black rubber sling, hung freely from heavy steel chains. “Lay down Pup” Ordered Luke, and as instructed Spike lay down on the cold tiled floor. On the table next to the sling Spike could see several metallic tools and instruments but couldn’t make out what they were. Luke knelt down beside his pup and slid his strong muscular arms under his pup’s body, he lifted Spike up and taking his whole weight lowered him into the sling. Taking hold of pup’s ankles Luke reattached the restrains, this time to the steel chains holding up the sling. After his legs were securely held in place pulled widely apart fully exposing his beautiful penis and large smooth balls, Luke secured Spikes arms to the chains at the top of the sling.

Spike lay happily in his rubber cradle, warm and content letting out he occasional bark, delirious and unbelievably horny from the GHB. Pre-cum still trickled from Spikes cock, dripping down on to his abdomen where it pooled in between his muscles before running down the side of his stomach. Periodically Luke would bend down and lick some from his pups cock. Luke played with his pup’s cock and balls, pulling on them and slapping them, each time making Spike jump and tense up. “Your still far too sensitive for what I’ve got in mind for you Pup, I think you might need a little something to take the edge off, what do you think?” Spike barked loudly and nodded his head in agreement. Luke reached down to the small table he had prepared next to the sling, among the various medical instruments was a syringe filled with more clear liquid. He picked up the syringe and dipped it into a large tub of lube. He smeared the lube over the end of the syringe and slowly inserted it in Spikes arse. Slowly he pushed down on the plunger until all of the liquid was inside his pup. To stop the liquid from escaping Luke promptly lubed up a large but plug and pushed it inside Spike.

As the liquid now inside Spike was quickly absorbed into his blood stream he could hear a fizzing noise in his ears and everything began to slow down. The high dose of Ketamine Luke had dosed Spike with soon took hold. Spike, just able to hold his head up could see everything Luke was doing in the mirror on the ceiling. After an hour or so abusing his pup’s balls Luke held them tightly in his hand and looking directly into Spikes glazed eyes smiled as a the best idea he had ever had began to evolve. “You’ll let me do anything to you won’t you Pup?” Spike panting with his tongue hanging out nodded emphatically at Luke. Luke reached down to his instrument table and picket up a tick black zip tie. He slowly wrapped the zip tie around his scrotum close to the base of his cock. He fed the end through the lock at the other end of the zip tie and sharply pulled it as tight as he could. As the skin of his scrotum became trapped in the zip tie pup barely flinched. The Ketamine had nicely anesthetized Spike but he was still conscious enough to take in everything that was going on. Luke holding Spikes balls in his left hand slowly removed the sheath from a 21 gauge needle and slowly pierced the skin covering Spikes large now purple balls, as the sharp steel needle easily penetrated all the way into Spikes ball clear fluid began to trickle from the open end of the needle. Luke caught some on his finger and sucked it off. After inserting and removing needles into each of his now bloody and aching balls Luke knelt down, his face level with his pup’s crotch. He wrapped his lips around the balls in front of him, biting down hard on his balls making Spike flinch slightly. Luke rolled Spike’s balls between his teeth, applying pressure and then releasing. Luke licked the blood from Spike’s balls until they were clean again and then removed them from his mouth; the only marks that remained were some small red puncture sites from the needles and Luke’s teeth marks.

Luke stood back looking his pup up and down, how could he really make his pup real in pain? Luke walked over to a set of draws at the far end of the room, kneeling down he opened the bottom draw. From out of the draw he pulled a large power tool that looked a little like a drill, Luke plugged it in and made his way back over to his pup hanging happily in his rubber sling. He held the tool up so his pup could see Luke’s new toy; it was nail gun! Luke didn’t even wait for approval from Spike he grabbed pup’s balls, holding them outstretched from Spikes body and positioned the nail gun beneath his left ball. Sweat was running furiously down Spikes forehead but his cock was harder then ever. Luke pulled the trigger on the industrial power tool and instantly a 6” steel nail fired straight through Spikes ball and shot out the other side. Spike screamed out with the sudden pain. Luke proceeded to do exactly the same to Spikes other ball, again the poor pup screamed out in agony. Luke once more stood back and admired his work. After the initial shock and agony of the traumatic impaling of his balls by two large nails Spike savored the sight of his huge smooth balls scoured by the sharp metal.

From out of the same draw as the nail gun Luke took a small black box with two prongs sticking out of the top of it. He moved it closer to Spikes impaled balls until the two prongs on the black box were touching the two nails one on each side. Luke squeezed the button on the side of the box and like a flash 5,000v of electricity surged out of the taser down the two nails into Spikes balls and into his body. The intense pain caused Spike to jump up and thrash around frantically, Luke shocked his pup again and again and again, tears ran down Spikes face, the pain was unbelievable. On the sixth shock pup’s cock gushed creamy white cum. Spurt after spurt shot over Spike’s shoulder and landed on the floor beneath him, some of the cum landed on pup’s face, Spike quickly lapped it up, a reward for enduring his masters abuse. The pain in Spikes testicles was unbearable; Luke gave him another large dose of Ketamine before removing the two nails from his balls. The pain still overwhelmed the damaged little pup, Spike begged for the pain to stop, anything to stop the agony.

Luke covered his pup’s groin in antiseptic solution and slipped his hands into sterile gloves, holding the bruised and bleeding balls is his hand he picked up a scalpel from the near by table, slowly and thoughtfully he dragged the fresh blade through skin of spikes scrotum the stinging from the blade masked my the Ketamine and the sheer agony he was already feeling. He exposed both of his swollen and mutilated balls and carefully tired suture around the blood vessels leading to the balls isolating and starving them even further of blood. Luke stuck out his tongue and licked Spikes right ball, he sucked it into his mouth it felt warm and smooth. Spike couldn’t believe what he was witnessing in the mirror, what a magnificent sight, he’d never been so turned on, wanking spikes cock with one hand and holding his balls with the other Luke bit down on the sperm cord and blood vessels severing them from spikes body, he lifted his head and held the severed ball in in teeth, showing it to spike. For the second time spike began to cum, as Luke bit down as hard as he could on spikes severed ball it exploded in his mouth with a loud pop and he gulped down the pieces. Spike was still cumming as Luke bit off Spikes second ball. Luke bend over and with the ball in his mouth kissed Spike; Luke spat the dead testicle into the mouth of his freshly neutered pup. Spike, with a look of satisfaction that Luke had never seen before chewed and chewed until there was nothing left of his testicles.

Spike who had closed his eyes to savor the taste of his own balls opened them again quickly when he heard Luke opening a plastic packed, “I have one last surprise for you Pup”. Luke held up the two large stainless steel balls he had just removed from their sterile packaging. One by one Luke inserted them in to the empty sack where his real balls had once been. Spikes scrotum was now tightly packed with two metal balls the size of pool balls, they stretched his scrotum tight and Luke struggled to suture the wound closed. Once he’d finished he let his pup’s new balls hang down, they pulled heavily and felt amazing. Rock hard balls rubbing on his perineum, bouncing up and down and Luke wanked Spikes cock one more time.
