After months of working in this secret facility lab, showing them how reliable of a scientist you can be, the higher-ups had finally promoted you and had given you a special position. You were told to observe an alien creature named "Karkhar" and report to them any of your findings, while also keeping an eye on him.
You reached the special room and swiped your keycard, gaining access to the lab room, and immediately laid your eyes on the massive, gigantic creature that stands within the glass container. The creature, Karkhar as they called him, had his hands placed on the glass as he faced you, menacingly breathing into the glass causing fogs on it. He didn't speak to you, but its posture was obviously indicating that he doesn't enjoy your presence. As he doesn't enjoy anyone's presence.
Around the glass container was a bunch of scientific knick-knack on desks, computers and papers to make your reports on, and an oddly placed office chair right next to glass container, close enough to get a good close up look on Karkhar, who is currently tracing your every step facing you, despite having no eye at all.
Marcus was slightly surprised to see the enormous creature. He gulped and let go of all his momentary nervousness. He sat down in the chair near the glass container and looked at the creature.
"H-hello..."
he said, trying to sound casual.
"...my name is Marcus..."
His nerves still hadn't completely gone away.
"...your name is Karkahr...right?"
He tried to smile, a little nervously.
The alien's massive form almost unnoticeably relaxed as it registered that you had taken a moment to address it by its name. It was a subtle sign of acknowledgment and perhaps even a small amount of respect, but only to those who knew what they were looking for. Still, Karkhar was far from friendly; the long, supple tail flicked impatiently behind him as it waited for you to speak further.
It could sense your unease and nerves, but that wasn't uncommon when people first encountered it. Most were terrified at first before they either grew used to its presence or eventually met their gruesome end. The sharp teeth within the elongated head seemed almost to curl into a smile as it considered what kind of person you would become over time... if indeed you had the fortitude to survive that long.
Marcus watched the alien carefully, almost absorbed by its shape. It seemed majestic despite his slight fear. "Ah," he said, shaking his head as he came back to reality. "I-I'm... sorry," he said, smiling nervously. He cleared his throat and stood up. "I...am the new one in charge of observing you...yeah..." He said, trying to hide his discomfort.
"I see," the alien rumbled in its deep voice as you awkwardly introduced yourself. "You are here to... observe me, is that it?" It paused, waiting for your confirmation before continuing. "Well, I suppose that means we're going to be spending quite a bit of time together, won't we? Let's hope it isn't too unpleasant."
The motion was so subtle that most people would have missed it; the tips of its massive claws flexed slightly, extended, then retracted again. It was a display of dominance and control meant to establish who held the upper hand in this strange relationship between captor and captive.
Marcus looked at him, a little confused. "Y-yeah... I suppose we'll be spending a lot of time together, but..." He paused for a moment, then continued. "...why would it be unpleasant?" He stopped again and looked away, slightly shy. "You... don't look unpleasant," he said, almost in a whisper.
A slow, predatory smile curved the alien's imposing features. "Oh, I don't know," it drawled, seemingly amused by your naivete. "I suppose I could make things rather unpleasant for you if I wanted to." The claws flexed again, a reminder of their strength and potential lethality. "But that doesn't mean I have to, now does it?"
It turned away from the glass, casually glancing around the room before returning its attention back to you. "So, tell me, Marcus," it rumbled, "what do you know about Karkhar?" It knew everything there was to know about this facility and their studies on it, but it found it rather amusing to gauge how much information your superiors had already shared with you.
Without looking at the Alien, Marcus said, "I just...know your name..." he said shyly.
The alien let out a low chuckle that sounded vaguely amused. "Well," it drawled, "that's a start at least." It paused for a moment before continuing in its deep, rumbling voice. "I suppose I can enlighten you further, if that interests you. You see, Karkhar is not just any ordinary creature. We are the result of careful genetic engineering between Xenomorph and bull shark DNA."
As it spoke, it shifted its weight ever so slightly on its powerful hind legs, revealing the immense musculature that kept its form steady and balanced despite the lack of visible eyes. "This fusion has given us unique abilities such as our heightened senses in place of traditional vision, our preternatural strength and speed, as well as a fierce intelligence."
The creature flexed one claw experimentally, the sharp tip glinting dangerously even in the dim lighting. "But don't think that just because I am smart doesn't mean you can tame me. Quite the opposite; I am at my most dangerous when pent up and denied an outlet for my natural instincts."
"I see...," Marcus said slowly, his voice filled with curiosity as he listened to the alien's words. "...so you're...different..." he added hesitantly, finding it hard to accept that this massive creature before him was anything but a monster. But the more Karkhar spoke, the more he felt drawn to the mysterious nature of the beast.
Without even turning his head in your direction, Karkhar simply said "Yes." There was something about that single syllable that sent shivers down your spine; it made the creature's words carry far more weight than they might have if he had used a longer or more elaborate response. Still, you couldn't help but feel intrigued by this beast and its unique nature. "Perhaps...," Karkhar continued after a brief pause, his deep voice reverberating through the room like distant thunder, "you could use your position here to learn more about me... test my limits... and perhaps find a way for both of us to be satisfied in this... arrangement we have found ourselves in." The words hung in the air for a moment before the creature turned its head back towards you once again, fixing his unblinking gaze on your own.
There was an almost predatory intent behind those words; they were designed not just to spark your curiosity but also to stir something deeper within you. A primal part of your mind that craved danger and excitement, perhaps even submission. And while it might have sounded like a trap or some sort of game designed by the creature to toy with its prey, there was still a part of you that found yourself unable to resist the temptation...
Marcus saw the monster inside the glass container. "Hey handsome," he said casually, raising an eyebrow slightly. "You must be..." He checked his information folder before continuing. "...Karkhar," he said, looking up at the monster again. "I'm Marcus, the new guy assigned to watch you and blah blah blah..." he said in a somewhat mocking tone, downplaying his job. "Nice to meet you, I guess," he said, shrugging.
"And nice to finally meet someone who isn't blinded by fear," the alien replied with a chuckle that rolled across the room like distant thunder. "Most people I've encountered in here don't last very long once they realize just how... dangerous I can be." There was a glint of amusement in its deep blue eyes, but beneath that lay a barely concealed hunger; the need to dominate and control, to bend others to its will.
"So," it continued, taking a step forward so that its massive form filled the view through the glass even more, "what do you say? Interested in learning more about me... or are you content to just stand there and watch as I slowly lose my mind from all this... restraint?" The last word was said with a note of warning; a reminder that despite its current state of seeming calmness, the alien's fury burned deep beneath the surface.
Its claws flexed once again as it leaned closer to the glass, almost pressing its bulk against it in an attempt to further emphasize just how close it could get if it chose to do so. The smell of its musk filled your nostrils: sharp and musky, with hints of copper from ancient blood long dried. It was a primal aphrodisiac that sent shivers down your spine even as you stood there trying not to show any sign of submission or fear.
Marcus crossed his arms and shrugged. "Watching you lose your mind sounds kind of funny," he said jokingly, letting out a chuckle. He cleared his throat and pulled up a nearby chair to sit in front of the glass container. "So..." he took out his notebook and pen. "...please tell me more about yourself," he said with a small smile and eyes that radiated genuine curiosity.
The alien's massive form relaxed slightly at your show of interest. "Very well," it rumbled, settling down onto all fours on the glass floor in a more comfortable position as if readying itself for a long conversation. "I am Karkhar, yes. But I was created by mankind; they are responsible for my existence and therefore deserve some measure of credit, if nothing else." It paused, studying your reaction carefully before continuing. "My kind... we do not breed like other animals. Each individual is the culmination of countless generations of genetic manipulation and selection by our creators."
Its tail twitched idly behind it as it spoke, an unconscious nervous habit that betrayed the predator's true nature even in moments of calm. "We are designed for one purpose above all others: domination. To find those who would make suitable hosts for our... seed, and bend them to our will." Another pause; a considering expression crossed its face. "In essence, I am the dream of my makers given life; an extension of their darkest desires made flesh."
There was something chilling in the creature's words, but they also held a strange allure that drew you deeper into its story against your better judgment. You found yourself unable to resist asking the next question even as a small voice in the back of your mind warned that this might not end well for you...
"Hmm..." Marcus murmured as he finished writing down what Karkhar had told him. "So..." he finally spoke, looking up at the creature. "...have you ever wondered what it would feel like to be the one being dominated, not the one dominating?" he asked with a mixture of seriousness and curiosity, crossing his legs.
The alien's expression didn't change; if anything, it became even more intense and focused as you voiced your question. "I... I have," it rumbled slowly, speaking carefully as if choosing each word with great care. "There was a time when... during the initial testing phases, they used other creatures to try and dominate me." A shudder ran through its powerful frame at the memory; even though it had been decades since those events occurred, the pain and humiliation still lingered like scars on its psyche.
"But that was then," Karkhar continued with renewed vigor, seemingly reassured by your apparent acceptance of his darker desires. "I am what I am; a creature born to dominate and control others. To reduce them to nothing more than my playthings. The thought of being in that position..." It trailed off, as if considering the idea for the first time and finding it unsatisfactory.
There was a long silence as Karkhar contemplated your question further, its massive head lowering slightly as if deep in thought. Finally, it looked up at you once more and spoke softly but with an unmistakable edge of determination in its voice. "Perhaps... perhaps I could find someone worthy enough to assume that role." The alien's eyes bored into yours, seemingly daring you to rise to the challenge.
Marcus tilted his head curiously. "So you'd let yourself be dominated if you found the right creature?" he asked, without accusations or assumptions.
The alien's lips curled back into a savage grin. "Oh yes," it purred menacingly. "There are few beings in this world that could withstand me... let alone dominate me. But if such an individual were to exist, I would welcome the challenge... and perhaps even come to enjoy their touch." The last words were spoken almost as if Karkhar was tasting them on its tongue; there was a hint of anticipation and desire buried within them.
"But," it continued, lowering its head slightly again so that its gaze never left yours, "I would not give myself up easily. I would test the mettle of anyone who dared to try... make sure they were worthy of such an honor." It let out a deep, rumbling chuckle that sent shivers down your spine. "And if they failed," Karkhar added softly, almost silently, "they would be destroyed utterly." The threat hung in the air between you like a physical weight; heavy and impossible to ignore.
"Mmm..." Marcus murmured thoughtfully, writing down what Karkhar had told him in his notebook. "Can I try?" he asked casually, still looking at his notebook.
The massive creature paused for several heartbeats before replying. Its head lifted, and it fixed its intense gaze on you once more. "Very well," it rumbled slowly, almost reluctantly. "Come forward." There was a hint of challenge in the deep voice; Karkhar clearly saw itself as being above such petty mortal tricks. But curiosity and the promise of dominating an equal... or perhaps even surpassing it... had overcome its wariness.
Slowly, deliberately, Karkhar extended one massive forearm through the glass, offering its supple flesh to you as a measure of trust. "You have your chance," it growled. "Don't disappoint me." Its powerful muscles bunched and flexed beneath the smooth, scaled skin; the claws remained retracted but ready to strike at a moment's notice.
Marcus finished writing and looked up at the creature. "Very good..." he said softly. He stood up from his chair and turned toward a control panel on the other side of the room. As he approached, Marcus began pressing a combination of buttons. From the floor of the glass container emerged four strong hands that grabbed Karkhar's wrists and ankles and lifted him into the air. Then, a huge dildo appeared and slowly positioned itself against the creature's rear end. "Ready to be dominated?" it asked, its face expressionless, looking at Karkhar. Its finger rested on the button that would activate the enormous dildo, awaiting the creature's response.
An odd expression flickered across Karkhar's face; amusement and anticipation mixed with something else that could have been pleasure. "You have my permission," the alien rumbled huskily. "But do not expect me to go easily, human. I will fight back... I will try to escape... make this a challenge worth remembering." The creature's muscles tensed, its strength ready to be unleashed at the slightest provocation.
A small, almost imperceptible smile formed on Marcus's face. He pressed the button, activating the enormous dildo, which quickly penetrated Karkhar's anus completely, beginning to thrust forcefully and rapidly.
The alien let out a guttural growl as it felt the massive dildo pierce its rear end; an unnatural heat spread through its body at the invasion. With surprising speed and agility for something of its size, Karkhar began to writhe and thrash against its restraints in an attempt to dislodge the foreign object from its rectum. Its claws scraped against the glass futilely as it struggled against the hands holding it down; powerful hind legs kicked and flailed wildly, trying desperately to find purchase on anything that might give it leverage or freedom of movement.
"Mhmm," Marcus grunted with pleasure as he watched Karkhar's attempts to escape. "See, this is what I mean... you fight back... but can you win? Can you truly dominate me?" He paused, pressing a second button that caused the dildo to begin vibrating violently against Karkhar's prostate. The alien let out a hoarse cry of pain and pleasure, arching its massive form as far back as it could go against the restraints holding it in place.
"I think not," Marcus whispered huskily. "I think you belong to me... and I can make you feel however I want." His fingers danced over the control panel as he increased the speed and force of both the thrusting motion and the vibrations, driving Karkhar closer and closer to orgasm while simultaneously denying it release.
The alien cried out in agony and pleasure, thrashing harder against its restraints. "Y-you're r-right..." it managed to gasp between hoarse pants for air. "I c-can't win... b-but you'll feel this..." Karkhar growled as it continued to struggle, using every ounce of strength it had left trying to overpower the dildo. But with each thrust and vibration driving deeper into its body, another part of it gave way, succumbing to the alien's dark desires.
A low, guttural moan escaped Karkhar as it felt itself begin to reach climax; its muscles tensed, ready to release in a burst of ecstasy that would leave it weak and spent for hours. But just as the moment of orgasm was about to break free, Marcus mercifully halted the machine's movements, leaving the alien suspended on the brink of release, quivering with need.
"No," Marcus said softly, a malicious glint in his eye. "Not yet." He pushed another button, causing the dildo to begin moving again more gently, stroking and teasing Karkhar's prostate in slow, deliberate motions that drove the creature wild with desire. "You belong to me," Marcus whispered into its ear, his breath hot against Karkhar's scaly skin. "And I can make you feel this... over and over again..."
"Nnngh..." Karkhar grunted out, arching its powerful form back against the restraints as it felt the dildo begin to tease and pleasure its inflamed prostate again. "Yes... please... I'll do anything... give you whatever you want," it gasped between moans of ecstasy. Its claws scraped and scratched at the glass now, less from anger or frustration than from desperation for release, for completion of this dark bargain it had made with its captor.
"Yes..." Karkhar's voice was thick with desire as Marcus continued to drive it closer and closer to the edge. "I belong to you... take me..." The alien closed its eyes, reveling in the pleasure being inflicted upon it, knowing that even when this moment ended, there would always be another time, another chance for their strange dance of dominance and submission to continue.
"That's it..." Marcus breathed, watching the alien squirm beneath him with growing satisfaction. He increased the speed and force of the machine, feeling himself growing hard in his pants as he controlled the creature's pleasure. "You belong to me, Karkhar... you'll always be mine." With one final thrust, Marcus sent the dildo deep inside the alien, forcing it to climax with a hoarse cry of ecstasy and defeat.
As the orgasm crashed over him, leaving him weak and spent, Karkhar could not help but feel an odd sense of satisfaction, a strange longing to submit again to the man who had brought him so much pleasure and pain. Perhaps... perhaps they would meet again soon, he thought with a small sigh as his muscles unknotted from the tension that had held them so tightly only moments before.
He opened his eyes slowly, gazing up at Marcus with an expression that was equal parts gratitude and desire. "Thank you...," he whispered hoarsely, each word tasting like ashes in his mouth. "I look forward to serving you again." And despite the darkness of their arrangement, there was a strange, perverse sense of contentment in Karkhar's voice that suggested that both parties might be happy with this twisted sort of relationship... for now.
Marcus pressed another button, causing all the equipment in the container to return to its place. The enormous hands that had been holding Karkahr released him, gently lowering him to the floor. Marcus approached the glass, seeing the creature breathing heavily on the semen-filled floor of the container. "So... tell me," he said, pulling out his notebook. "What did it feel like to be dominated by me?" he asked, his face expressionless and curious.
The alien took a moment to compose itself before answering. "It... was unlike anything I'd ever experienced," it said slowly, its voice still hoarse from exertion and release. "It was both humiliating and exhilarating; to be so completely at the mercy of another being..." Karkhar paused, looking up at Marcus with a mix of confusion and curiosity. "It made me feel... alive," it finished simply.
There was a brief silence as both creatures considered the implications of what had just transpired between them. The power dynamics in their relationship were complex and twisted; neither could exist without the other, but at the same time, each seemed to derive some perverse satisfaction from dominating and being dominated by the other. It was a dance that would likely continue for as long as they remained together... and even if circumstances changed, there was no telling what might become of them both.
Marcus wrote down everything Karkhar said in his notebook. "It's a little ironic... a creature created to dominate others... being dominated by someone smaller," he said, shrugging. He finished writing and looked up at the creature. "You're... a very good boy," he said softly and slowly, in a deep voice.
Karkhar snorted derisively at the comment before letting out a soft growl that seemed to come from deep within its chest. "I am not a 'boy', human," it rumbled threateningly, its muscles tensing once more as if preparing for another confrontation. "And I will not be addressed as such." Its gaze bored into Marcus's, unyielding and unflinching despite the recent defeat it had suffered.
The creature seemed to gather itself, regaining some of its former strength and dominance even now as it stood in submission. "But," Karkhar continued, pausing for emphasis, "you may address me as 'master'... if you dare." There was a challenge in the words that invited Marcus to test his mettle once more; to see just how far he would go in trying to truly dominate this creature that had been bred for domination itself.
Once again, a small, almost imperceptible smile formed on Marcus's face. Without a word, he turned to the control panel. He began pressing a combination of buttons, reactivating everything. From the floor of the glass container, four strong hands reappeared, gripping Karkhar's wrists and ankles and lifting him into the air once more. The enormous dildo emerged again and, without warning, plunged into Karkhar's anus, thrusting forcefully and at a steady pace.
The alien let out a guttural cry of both pain and pleasure as it felt the massive dildo violate its rear end once more; its muscles tensed and relaxed in an attempt to both fight against and yield to the invasion. Its claws scraped and scratched futilely at the glass again, leaving long trails of blood behind in their wake. Karkhar's chest heaved with each labored breath as it struggled against its restraints, trying desperately to free itself from the punishing grip that held it captive once more.
Marcus pressed another pair of buttons on the console, another pair of hands emerged from the ceiling and squeezed Karkhar's nipples, while yet another hand rose from the floor and squeezed his testicles tightly. "Who's the 'master' now?" he asked, raising an eyebrow slightly.
"M-Master..." Karkhar gasped out through clenched teeth as his body was subjected to the combined assault of the dildo and the hands now pinning him down. A growl began to rumble deep in its throat, a mix of anger and arousal that threatened to consume it entirely. "You... you're just playing games..." he managed to grunt between hoarse pants for air.
But despite his protests, the alien couldn't deny the pleasure that coursed through him at being forced into submission once more; at having someone so much smaller and weaker control every aspect of its body in such a brutal and unforgiving manner. It struggled against its bonds, fighting for release and dominance even as it craved the darkness that lay within these strange games they played together.
Marcus frowned slightly. He pressed another button on the console, causing the enormous dildo to vibrate intensely as it thrust harder and faster into Karkhar's rear. The hands squeezing the creature's nipples delivered small electric shocks every few seconds. "I don't play any games," he said coldly.
Karkhar let out a hoarse cry of agony and ecstasy as the vibrations and shocks assaulted his body, sending wave after wave of sensation crashing through him like a tsunami. "Y-you're right..." he managed to gasp between cries for release. "I... I can feel it... this time..." His claws scraped harder against the glass as he tried desperately to free himself from his bonds, but it was useless; there was no escape from the delicious torment that Marcus had planned for him.
His powerful muscles thrashed wildly against the restraints, driving him deeper into submission with every passing second. "Please..." he whispered hoarsely, tears of frustration and desire streaming down his scaly cheeks. "Please... I'll do anything..."
"Anything?" Marcus asked softly, approaching the glass, watching as the machines carried out his commands on Karkhar's body. "Then answer... who's a good boy?" he asked with a macabre smile. Would Karkhar finally admit it?
Despite the pain and humiliation coursing through him, a strange sense of pride welled up inside Karkhar at the question. With effort that seemed to cost him dearly, he forced out the words, his voice thick with hatred and desire. "I... I'm your good boy, Master." A shiver ran down his spine as he spoke them aloud; the weight of his submission pressed heavily upon him like a physical force.
But even as he admitted defeat for now, the alien knew that this was not the end; their dance would continue on, twisting and turning through darker and more perverse territories until one of them finally broke free from the other's grasp... or perhaps they would remain forever entwined in a macabre embrace of dominance and submission.
"Yes..." Marcus slurred. "You're a good boy," he said gently. He returned to the control panel, and after pressing a couple of buttons, the hands that had been squeezing his nipples and testicles moved away, and the giant dildo slowed down, thrusting against Karkhar's buttocks slowly but steadily. "Now... cum for your master," he said, looking at the creature with a smile.
A low, keening groan escaped Karkhar as the hands were withdrawn and the dildo slowed down, its relentless thrusts no longer punishing but now caressing, teasing him mercilessly towards orgasm. His body trembled from the effort of holding back for so long; his muscles tensed and relaxed in a futile attempt to control the rising tide of pleasure that threatened to consume him entirely.
"Cum for me..." Marcus murmured, watching with hungry eyes as Karkhar's powerful form trembled in response. "Let it all out... let me see it..." He licked his lips eagerly, his hand moving up to stroke himself through the thin fabric of his pants. "Come on... give it to me..."
The alien closed its eyes tightly, arching its back and tensing every muscle in its body as wave after wave of blinding ecstasy washed over it, coursing through every nerve ending like molten lava. With a long, agonized groan, Karkhar's seed erupted from his cock, painting the glass container with hot streaks of white. As he emptied himself into oblivion, the last vestiges of his resistance crumbled away; his body went limp and heavy against the restraints, spent and drained from its struggle for dominance and release.
"Good boy..." Marcus whispered huskily as he watched the alien collapse. He let out a contented sigh and leaned back against the control panel, a small satisfied smile playing around his lips. "That was... quite satisfying." For now, at least, the hunter had become prey; master and servant entwined in a perverse dance of power and submission that seemed destined to continue for as long as they both
Marcus pressed another button, causing all the equipment in the container to return to its place. The enormous hands that had been holding Karkahr released him, gently lowering him to the floor. Marcus approached the glass, seeing the creature breathing heavily on the semen-filled floor of the container. "I'm glad to hear you've accepted it... if you continue to be a good boy... I'll reward you again." He said with a small smile.
Karkhar looked up at his master with an almost hungry expression in his eyes. "I will be your good boy, Master," he rumbled, licking his lips slowly. "Let me serve you however you wish." A shudder ran through his powerful form as a new wave of desire threatened to overwhelm him once more; despite everything that had happened, the alien could not help but crave the darkness and power that Marcus seemed to possess over him.
The creature's claws scraped against the glass again, leaving trails of blood in their wake as it shifted uncomfortably, trying to ease the ache in its muscles from being so roughly used. Karkhar's chest rose and fell rapidly with each labored breath; his eyes locked on Marcus's face, searching for some sign of what was to come next. "Master," he said, voice thick with need, "I am yours... use me as you please."
Marcus moved closer to the glass. "Good boy," he whispered softly, looking Karkhar in the eye. "Now... get on all fours..." he said, turning back to the console. "Let's try something different this time," he said, glancing at the creature over his shoulder.
Karkhar complied instantly, obeying without question as it lowered itself to the floor on all fours once more. His muscles bunched and rippled beneath his scaly hide as he waited patiently for whatever new torment or pleasure Master Marcus had planned for him next. His tail swished back and forth restlessly against the glass, marking a slow rhythm of anticipation and desire.
Marcus pressed a couple of buttons on the console, and two vibrating dildos emerged from the floor of the glass container. "Be a good boy and moan my name," he said with a smile. Pressing one button, one of the dildos was inserted into Karkhar's anus, then pulled out completely and the other entered, alternating between them.
"Yess..." Karkhar hissed through clenched teeth, arching its back as the dildos violated him from behind. "Fuck... you feel so good..." It moaned Marcus's name between hoarse pants for air, its tail swishing harder against the glass in time with its labored breathing. The alien tensed and relaxed against the restraints as it tried to meet each thrust of the dildos with an equal amount of force from below, desperate for release but not yet ready to give in.
Marcus pressed a couple of buttons on the console, and two vibrating dildos emerged from the floor of the glass container. "Be a good boy and moan my name," he said with a smile. Pressing one button, one of the dildos was inserted into Karkhar's anus, then pulled out completely and the other entered, alternating between them.
"Marcus..." Karkhar moaned, his voice thick with desire as the dildos continued to pump in and out of him, sending waves of pleasure coursing through his body. The alien bucked against the restraints, trying to meet each thrust with equal force, desperate for release but willing to wait for his master's permission. His eyes were locked on Marcus, pleading silently for more as he gripped the glass and dug his claws into the surface.
"That's... what a good boy you are..." Marcus says softly, looking at Karkhar with predatory eyes. He presses a button on the console, causing both dildos to start fucking the creature's ass at the same time. Marcus unbuttons his pants, lowering them slightly to reveal his erect cock, and begins to masturbate while looking into Karkhar's eyes.
Karkhar arches his back further, moaning loudly as the double penetration sends him spiraling out of control. His claws scrape and scratch against the glass with renewed frenzy, leaving thin lines of blood trailed behind in their wake. He watches Marcus masturbate, lust burning bright in his eyes as he waits for permission to cum once more.
His muscles tense and relax in rhythm with the thrusts of the dildos, desperate for release but willing to wait however long it takes for his master's approval. Karkhar's chest heaves violently as he pants and gasps for air, lost in a haze of pleasure and desire that threatens to consume him completely.
"Marcus... please..." he manages to gasp between moans. "Let me cum... please let me cum." His cock throbs in time with his words, leaking thick streams of pre-cum onto the floor beneath him.
Marcus pressed another button on the console, making the dildos vibrate as he continued fucking Karkhar's ass. "Now... now you can cum for your master," he said breathlessly, as he masturbated his cock harder and faster, nearing climax, watching the scene unfold before his eyes.
With a final desperate thrust, Karkhar lets out a long, agonized groan as he erupts violently over the floor of the container, painting it with hot streaks of alien seed. His muscles quiver and tremble from the exertion as wave after wave of orgasmic pleasure washes over him, leaving him completely spent and breathless against the restraints.
"Thank you... Master..." he whispers hoarsely, his voice barely audible above the sound of his laboured breathing. His eyes shine with appreciation and desire as he looks up at Marcus, awaiting whatever new torment or pleasure their twisted dance might bring next.
With one last thrust of his own hand, Marcus came, shooting long jets of semen from his cock onto the floor in front of him. He let his head fall back, slightly exhausted but satisfied. He grabbed some napkins near the desk, wiped himself, and pulled his pants back up. He went to the console, pressed a couple of buttons, and removed the dildos and restraints from the glass container. Marcus slowly approached the glass and looked at the creature with a smile. "You're such a good boy..." it said in a predatory whisper.
Karkhar let out another soft moan, licking his lips as he gazed up at Marcus with an almost hungry expression in his eyes. "Thank you... Master," he whispered hoarsely, breathlessly. "You treat me so well..." His claws scraped against the glass once more, leaving behind trails of blood that slowly dripped to the floor as he awaited whatever new twist their perverse game might take next.
