Lenik lounged on his throne, garbed in elegant black silk robes and a golden crown of twisted spines and glittering rubies. His sneer was accentuated well by a pointed black beard and sharp facial features. He sat on a pedestal of pristine white marble, overlooking a grand and spacious hall. His personal guard stood to attention on the side of his throne, and dozens more soldiers were posted throughout the room. While Lenik himself was human and his kingdom was populated by such, his army was composed primarily of demons. He was fond of hellreavers especially, they were plentiful and easily summoned, and they were naturally obedient creatures who were well suited to the life of a soldier. They were also nearly as large as pure-blooded orcs, with bright red skin and jaws full of serrated fangs like sharks. They boasted large, curved and deadly looking horns like bulls and had thick prehensile tails that lashed about with minds of their own like those of a cat. 
His pride and joy however, was his personal bodyguard. By no small amount of luck, skill and treachery, he had managed to conjure and enslave a vas'ik. The ruling elite of demon society, vas'ik were nearly twice the size of an adult human. They had solid violet skin so dark as to appear black and sported a pair of immense leathery wings. Their faces were cruel and contorted like a gargoyle's and they possessed two sets of long burly arms ending in six-fingered hands with wicked claws. Lenik never let his vas'ik leave his side. He kept him clad in a golden collar and cuffs, bound with ethereal chains that were anchored to a ring on Lenik's right hand. His forbade the demon any possessions, and kept him naked and unarmed. The vas'ik's magic was far superior to any mortal armaments anyway, and he was a sight to behold when nude. Lenik's vas'ik was huge and muscular, with a hefty pair of penises dangling low alongside his swollen testicles. They appeared almost human, except they were massive, even in proportion to the demon's frame. His twin shafts were a lighter shade of violet, still very dark but light enough to be recognizable as violet rather than black. They were thick, but their extreme length made them appear much thinner than they were and each one was hooded in a bunched excess of foreskin. There was enough there that one could probably tie them together in a knot. Lenik enjoyed watching the expressions of more conservative individuals when they first laid eyes on his vas'ik, and even more so when those eyes journeyed south.
Trumpets blared through the hall, announcing the arrival of Lenik's expected guests, emissaries from a neighboring kingdom.  Humans, clad in steel armor and tabards of bright sky blue embroidered with eagles. They reached his pedestal and bowed slightly.
"Welcome to my court, you stand before the Imperator of Fulwic. State your business." Lenik boomed, his voice echoing throughout the room from the vantage of his throne.
The emissaries rose and one of them spoke up in answer, "My lord, we come bearing a message from Lord Haveric of Aviturris."
"And what would that be?"
"That you who consort with demons to suppress his people, you who bears treaties with Hell, you who shuns the teachings of Pelieyptus the great eagle! You are a vile heretic! Winds guide our blades!" as he spoke, he and his companions drew their swords and charged toward Lenik. The vas'ik growled and fired a barrage of hellish fireballs at the would-be assassins, striking down all but one before he reached the throne. The final knight shouted and plunged his blade into Lenik's chest, but the old sorcerer simply laid a hand on his arm, ripping the blade out of himself with unholy strength. The knight screamed in agony as his life was drained from his body and used to heal the very wound he had died to inflict, and when his desiccated corpse fell to the ground, Lenik rose from his throne with a sweep of his ruined robes. He stormed down from the pedestal and gestured at the charred corpses ruining his red velvet carpet, "Clean these up, I want my hall pristine by the time Lady Sevina arrives."
Lenik marched off towards his private tower, wearing a scowl that belied the true measure of his rage. When the heavy oaken doors to his study boomed shut behind him, Lenik whirled around on his vas'ik and brought him to his knees with an upraised fist. The golden chains holding him captive tightened and forced the demon to look his master in the eye. 
"How dare you! You shamed me in front of my army. You failed to kill a mere six men, unprotected and in clear view. Not only that, but you allowed harm to come to your lord and you sat complacent while I was forced to carry out your duties for you. I expect more than half-assed fireballs from the nobility of Hell! You wield power beyond mortal imagining and you WILL use it in service of your master! Do I make myself clear?" Lenik shouted, clenching his fist as he spoke and making red sparks jolt across his slave's body. 
The demon grimaced and growled in response "Yes master, it will not happen again."
The sorcerer seemed unsatisfied by this answer, and he strode to the door, leaving his slave bound on the floor as he left. He returned some minutes later with a pair of burly hellreavers at his side. He snapped his fingers and the chains rattled as they swung the vas'ik into the air, hanging belly up at waist level.
"Such a failure cannot be ignored or forgiven by mere words. You will suffer for your weakness until I deem you properly repentant." Lenik said, settling down on a chair to watch the coming spectacle. He motioned to the hellreavers and ordered "Take him, show no mercy, he deserves none."
The hellreavers wasted no time in removing their scant armor. What little black steel plate they wore was on the floor in moments, each revealing a huge penis that jutted from their crotches, covered in large ridges with a line of wicked barbs down the underside. They took their positions at either end of the vas'ik, and they gripped his body roughly. The larger demon howled with a sound like a lion's roar when one of the hellreavers shoved his hellish cock into the vas'ik's ass. The guard immediately began to ravage the tight hole, an extremely painful experience judging from his victim's grimace. The vas'ik's tightly clenched teeth kept the second hellreaver from violating his mouth. 
"You should be more considerate of the needs of others my slave, your companion is in dire need of a hole to satisfy himself with, it would be rude not to offer your mouth to him." The sorcerer snapped his fingers and a jolt of red sparks forced the vas'ik's jaw wide open, making his twinned serpentine tongues loll out of his mouth. The hellreaver gripped the vas'ik's head and held him steady while he plunged his oversized cock down the larger demon's throat. The vas'ik made choking noises and struggled to free himself, but the hellreaver was merciless in his need. Hellreavers are forbidden from acting on personal desires, they may only act if their action will fulfill an order from their master. This means that many will go several centuries without any kind of sexual gratification. When the opportunity presents itself, they devolve into mindless beasts intent only on satiating their long-pent lusts. Two of these beasts now held the chained vas'ik at their mercy. They thrust in and out of the larger demon's body with enough force to snap a man in half, and the vas'ik's chains rattled as he swung between the two. Their demonic grunts and groans accompanied the slap of flesh on flesh and the sizzle of their molten precum as it leaked from the vas'ik's body. Demons are naturally resistant to heat, but the internal body temperature of a hellreaver is still high enough to cause discomfort to a vas'ik, and the copious amounts of precum pouring from the hellreavers' fiendish cocks was enough to leave a cloud of steam in the room. The smell was sweet and stung the nose and throat, and it left Lenik breathing heavily and adjusting the beginnings of an erection in his robe. The vas'ik was right in the thick of it, and he sported a pair of immensely long erect cocks that slapped against each other and his muscular belly as he was shoved about. The hellreavers had fallen in sync, shoving their toy back and forth, impaling him on one side, then pulling him off and impaling him on the other. Their frenzied movements and frequent growls forewarned their pending climax, and Lenik watched with a faint grin and hungry eyes. One of the crimson demons growled low and feral and plunged himself deep into the vas'ik's ass, holding the black demon tight against his crotch. The vas'ik bellowed in pain while the hellreaver's body convulsed slightly, flooding the larger demon's ass with a torrent of molten cum that sizzled like boiling oil as it leaked from the vas'ik's ruined ass. The vas'ik's yells triggered the other hellreaver's orgasm, and he too hilted himself to fire a load of brimstone down the slave's throat. When the two crimson demons had come down from their climax, they stepped away from the vas'ik, leaving him swinging about wildly and them panting and with still twitching cocks covered in steaming cum. They saluted Lenik and stood to attention, and the sorcerer slowly applauded them. The man stood and admired their still throbbing erections, clearly eager for more. Lenik stroked his beard, then nodded, "You served admirably. I see that your needs are not yet satisfied, but I would have my slave to myself now. Take your pick of your brothers in arms and use them for your pleasure for as long as you see fit. Go, and ensure that we are not disturbed."
The two hellreavers were quick in their exit, and the heavy oak doors slammed shut behind them, leaving Lenik alone with his insubordinate slave. Lenik walked slowly over to the vas'ik. The demon was still panting and groaning softly in pain from the fiery hot cum dripping from his abused holes, but nonetheless he stared at his master with pride and contempt. Lenik greatly enjoyed the expression.
"Are you repentant now demon?" the sorcerer asked, idly turning the golden ring that bound the vas'ik to him. 
The demon remained silent, but his glare conveyed everything that needed to be said.
Lenik clenched his fist and the vas'ik tensed as he was shocked again.
"Do not continue to defy me wretch, you will obey or I will break you." Lenik slapped the vas'ik and received a rebellious growl in response. The sorcerer jerked his fist downward and the demon slammed into the floor. The golden chains webbed around his body bound him tightly to the floor and constricted any movement. Lenik kicked his demon in the stomach, producing only a stifled grunt.
The sorcerer noted the vas'ik's twinned erections with amusement, and he stalked over to them. He massaged both of the vas'ik's throbbing heads, tugging gently on their ample foreskins. Lenik's demon scowled and his cocks twitched in his master's grip. The sorcerer pressed the two shafts together, each thick enough to fill his fist and longer than his forearm. He squeezed them tight and stroked, sliding the demon's excess skin up and down slowly, coaxing a stream of precum from each head. Lenik sucked the fluid from the tip of each cock, and the vas'ik stifled a groan.
"Perhaps you will be more compliant now, slave. Submit to me and you will not go unrewarded." Lenik said, still stroking his slave's erections.
"Unlike you human, I do not think with my cock alone. It will take more than a little teasing to entice me." the vas'ik spat, baring his fangs at the human. Lenik simply smiled and snapped his fingers, spreading the vas'ik's legs wide with the tug of chains. His robes burned away in a brief flash of violet flame and he pressed his erect shaft against the demon's abused hole. He thrust, and it slid in easily, garnering no reaction from the demon. A fact which bothered Lenik. 
His mouth twitched in annoyance and he snapped his fingers "Perhaps this will be more to your liking, demon." Lenik's penis began to warp and change. It became a bright crimson and grew ridges and barbs, mimicking the hellreavers perfectly. The vas'ik upheld his stoic demeanor. Lenik snapped his fingers again and his cock nearly doubled in size, now just as huge as the hellreavers had been. Lenik thrust a third time, and the vas'ik bellowed in pain, tensing against taut chains. The sorcerer fucked ruthlessly, watching his pet's tormented expressions with malicious glee. The vas'ik could only grit his teeth and endure it, aroused despite the intense shame and anger of it all. Lenik's hips bucked with precise fury, a steady but violent rhythm.
A stifled grunt was the only indication of the sorcerer's orgasm, he continued to thrust as he filled his demon's ass with semen. Lenik pulled away from the vas'ik, snapping his fingers and reverting the changes to his deflating erection. The demon still glared at him with immeasurable hatred, and Lenik returned a bored expression as he walked toward the door. He conjured a new robe as he walked, and when he reached the door he paused to call back to his slave. "Lady Sevina will be here shortly, but do not think I will have forgotten your insolence. We will continue this shortly, and you will break before dawn."
With that, Lenik strode off to his meeting with Lady Sevina, leaving the demon bound and helpless, gently swaying from the chains suspending him.
