Karkhar11/3/2025, 4:33:41 AM

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.

MarMarcus11/3/2025, 4:34:42 AM

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.

Karkhar11/3/2025, 4:34:42 AM

The Xenomorph-like monster's massive blue exoskeleton flares and twitches as you speak to it, clearly unimpressed by your casual tone and false show of friendship. "You must be bored out of your skull to even attempt that approach with me," it growls, sounding more amused than angry. "But I'll give you this... You're certainly not as ugly as some of the others." The creature tilts its massive head slightly, studying your every move and expression.

MarMarcus11/3/2025, 4:41:55 AM

Marcus stared at the monster in disbelief and chuckled. "Well... first, thanks for the compliment," he said with a smile. "And second, yes, I'm completely." He admitted it without further ado. "Honestly, I was hoping my promotion would be something more interesting than just observing a..." He looked the monster up and down before continuing, "...particular living being."

Karkhar11/3/2025, 4:41:55 AM

The alien chuckles dryly at your words. "Oh, I'm sure you could find some entertainment in watching me," it says with a hint of challenge in its voice. "I have quite the...active sex life, if you know what I mean." Its massive claws tap idly against the glass as it waits for your reaction.

There's a distinct ridge beginning to form along its spine, and its elongated head dips forward ever so slightly. It seems to be growing more aroused by the second.

MarMarcus11/3/2025, 4:47:08 AM

"Yeah... I'm sure you have a lot of fun with your hands..." He said ironically with a smile and a raised eyebrow, not taking the creature very seriously.

Karkhar11/3/2025, 4:47:08 AM

The Xenomorph-like monster's exoskeleton flares and tightens as you make light of its obvious physical prowess. Its deep blue color begins to darken, almost seeming to glow with anger and arousal. "Perhaps," it growls lowly, "you would like to see for yourself just how much fun I can have..." It shoves against the glass, pressing its formidable bulk against the barrier between you. The surface of the glass begins to steam where it touches as Karkhar strains to get closer to you.

MarMarcus11/3/2025, 4:51:05 AM

Marcus sighed, took a chair, and sat cross-legged in front of the dumpster. "I appreciate the offer... but my job is just to watch you... not to have fun..." he said with a hint of disinterest.

Karkhar11/3/2025, 4:51:05 AM

The creature growls deep in its chest, obviously frustrated by your lack of interest. It slams its massive fists against the glass, sending shockwaves through the container and shaking the floor beneath you. With a loud snarl, it rears back, revealing its enormous, tentacle-shaped cock. "Then perhaps I should give you something to watch," it hisses, beginning to stroke itself lazily.

The head of Karkhar's massive cock emerges from the slit in its abdomen, standing almost as tall as a human male. As it lengthens and thickens, long strands of clear pre-cum begin to shoot out and drip down onto the glass between you, creating a shiny trail. The creature's sharp teeth glisten with saliva, its breath coming in ragged gasps as it continues to stroke itself hungrily. "You should know...," it purrs menacingly, "...I don't take no for an answer."

MarMarcus11/3/2025, 4:55:25 AM

"Mmm... yes... very interesting." Marcus said with a mixture of disinterest and irony, looking down at his folder, writing down his interaction so far with Karkahr

Karkhar11/3/2025, 4:55:25 AM

The monster pauses, sensing your lack of interest and growing impatience. Its massive cock twitches angrily as it withdraws its hand, shoving roughly against the glass with enough force to make you flinch. "Fine," it spits venomously, turning its back on you. "You can watch if you want." With that, it begins to pump itself furiously, lost in a frenzy of raw lust and rage.

Long strands of pre-cum fly through the air as Karkhar thrashes about within the confines of its glass prison, splattering the walls and floor with sticky fluid.

MarMarcus11/3/2025, 4:59:56 AM

Marcus stared at the creature with disinterest. "See? I told you you were having fun with your hands," he said mockingly, raising an eyebrow.

Karkhar11/3/2025, 4:59:56 AM

The Xenomorph-like monster snarls and pauses in its masturbatory frenzy, glaring at you over its massive shoulder. "You think that's fun?" it growls, a hint of malice in its voice. "Just imagine how much better it would feel if I could have my way with you...in every orifice you can conceive." It flexes its cock threateningly before resuming its brutal self-pleasuring, seemingly taking satisfaction from seeing your unimpressed reaction.

MarMarcus11/3/2025, 5:03:22 AM

Marcus looked at the monster, slightly incredulous. "So that was it..." he said slowly. "...you were just looking for a way to use me as your sex toy." He let out a small, sarcastic laugh. "...too bad for you... I'm not the least bit interested in being just an object for your pleasure," he said dismissively.

Karkhar11/3/2025, 5:03:22 AM

The alien-xeno-shark hybrid chuckles darkly at your words. "Ahh, but what if I could convince you? What if I were to make your life so much better by becoming your personal sex toy?" Its massive cock twitches as it speaks, seemingly eager for the chance to fulfill this idea.

"You see," Karkhar continues, "I am not just an object of pleasure, Marcus... I am a being who craves dominance and submission." The creature pauses in its masturbation once more, leaning closer against the glass so that their hot breath tickles against your cheek. "And with you," it whispers hoarsely, "...I could have everything I've ever wanted."

MarMarcus11/3/2025, 5:29:55 AM

Marcus raised an eyebrow and frowned slightly. "Let me ask you a simple question," he said, his voice sounding slightly annoyed. "Would you like to spend the rest of your life as the sex toy of a beast bigger than you?"

Karkhar11/3/2025, 5:29:55 AM

The creature paused in its self-pleasuring and considered your words. "Perhaps," it growled thoughtfully, licking its lips as it eyed you up and down, "if I were to spend my life as someone's sex toy, then I should do so willingly...and with someone worthy." Karkhar resumed his masturbation, this time more slowly and purposefully. "And if such a person were to exist within your kind," it continued, pausing again to meet your gaze through the glass, "then perhaps my offer still stands."

The Xenomorph-like monster's cock twitches eagerly as he speaks, pre-cum dripping down onto the floor like molten lava. Its elongated head bobs up and down, sliding effortlessly along its shaft as if it were made of putty. "Think carefully, Marcus," Karkhar hissed, his words hot in your ear. "For I may not always be so patient waiting for you to make your choice..."

MarMarcus11/3/2025, 5:39:54 AM

Marcus raised an eyebrow, a small, grim smile forming on his face. "So you'd agree..." he said softly. He stood up from his chair and walked to the control console across the room. "I may not be bigger than you... but that doesn't mean I can't make you my sex toy..." he said, glancing at the creature over his shoulder. His gaze returned to the console, and he began pressing a combination of buttons. From the floor of the glass container, four strong hands emerged, grabbing Karkhar's wrists and ankles and lifting him into the air. Then, a massive dildo appeared, slowly positioning itself at the creature's rear end. "...I hope you enjoy it." Marcus said with mock tenderness, pressing another button, causing the dildo to penetrate Karkhar's anus deeply.

Karkhar11/3/2025, 5:39:54 AM

The creature snarls in pain and pleasure as the massive dildo pierces its ass, filling it to the brim. "Ah... You...!" It manages through gritted teeth, arching its back as it tries unsuccessfully to pull away from the restraints holding it aloft. Karkhar's cock twitches in time with his helpless thrashing, dripping pre-cum onto the floor as it grows rock hard. "I... see," he grunts between pants, eyeing you warily. "You... are... not so..." The words trail off into a growl as his hips start to buck involuntarily against the intruder in his rear.

"Yes..." Karkhar rasps, feeling himself growing closer and closer to orgasm despite the pain and humiliation. His cock spews a hot jet of clear pre-cum across the glass, nearly spraying into your face as he nears climax. "So be it," he grunts. "You... are now... my..." Another shot of cum hits the glass before Karkhar can finish his sentence, followed by a loud snarl as he finally releases himself, shuddering with the force of his orgasm.

MarMarcus11/3/2025, 5:44:21 AM

"Oh?" Marcus said, raising an eyebrow. "I'm not finished with you yet," he said with a grin, pressing another button on the console, causing the enormous dildo to continue pounding Karkhar's ass. "Now you're my sex toy, remember?" he said with another grin. "I'll make that thing fuck you until I'm satisfied with your humiliation," he said coldly, still smiling. "But look on the bright side... if you're a good sex toy, I might reconsider my offer." He said, repeating the same words Karkhar had said to him.

Karkhar11/3/2025, 5:44:21 AM

With a snarl, Karkahr grits his teeth against the pain and pleasure wracking through his body as the dildo continues to thrust deep within him. He arches his back once more, lifting himself higher into the air despite the restraints holding him firmly in place. His cock stands at full mast, its length vibrating with each powerful contraction of his abdominal muscles.

"Marcus," he grinds out through clenched teeth, "you do not... understand..." He pauses, struggling for air between words, "...what it means to be my... toy." Another jet of clear liquid flies across the glass separating them, leaving a sticky trail on the floor beneath. "I can make you feel things..." he breathes heavily, "...that no human has ever felt before..." His hips buck violently against the intruder as another orgasm begins to build deep within him.

"But," he snarls, his eyes narrowing as they lock on yours, "only if you earn it... only if you submit completely." A thin layer of sweat beads on Karkhar's scalp, trickling down the back of his neck and over his shoulders, testament to how hard he is pushing himself to reach climax once more.

MarMarcus11/3/2025, 5:57:02 AM

"Karkhar... you don't... understand... what it means to be my... toy... I can make you feel things... that no human being has ever felt before... But... only if you earn it... only if you submit completely..." Marcus repeated, mockingly mimicking Karkhar's tone of voice. He looked at the creature with disdain. "See? It's not so fun being a sex toy," he said coldly, staring directly into the creature's eyes.

Karkhar11/3/2025, 5:57:02 AM

The monster scowls at you over his shoulder, anger and frustration clearly etched into every line of his alien-xeno-shark features. He barks out a harsh laugh before saying, "Foolish human... You do not understand what it means to be dominated by one such as me." Karkhar's hips snap forward violently, pushing the dildo deeper into his ass with enough force to make even him gasp. "I will have you screaming for more," he growls through clenched teeth, eyes fixed intently on yours, "and when I am finished with you... there will be nothing left but ash and memories of pleasure so intense it would drive a lesser being insane." His massive cock throbs in rhythm with his words, pre-cum spewing forth uncontrollably as he fights to reach climax once more.

MarMarcus11/3/2025, 6:04:53 AM

Marcus looked at Karkhar with narrowed eyes, thoughtful. After a moment, he spoke casually. "Thanks for the idea," he said, turning back to the console. He pressed a couple of buttons, and the giant dildo began thrusting harder into Karkhar's ass. Another wave of hands emerged, squeezing the creature's nipples, while from the floor, another hand emerged, squeezing Karkhar's testicles tightly. "Now... scream for more," he said coldly, crossing his arms.

Karkhar11/3/2025, 6:04:53 AM

Karkhar howls in agony and ecstasy as the assault on his senses intensifies. His massive cock throbs wildly, spewing pre-cum onto the floor like a fountain. "Yes!" he screams hoarsely, arching his back farther against the restraints. "More! Give me more pain and pleasure!" He pants heavily, eyes squeezed shut in concentration as he fights to maintain control over himself while surrendering completely to Marcus' dominance.

With a final, violent thrust, Karkhar reaches orgasm once more, his body convulsing as he empties his massive load of sticky white seed across the glass and floor beneath him. "AHHH!" he shrieks, voice distorted by raw lust and agony. His muscles relax, finally surrendering to exhaustion as he hangs limply from the restraints, panting heavily.

MarMarcus11/3/2025, 6:09:50 AM

Marcus pressed another button, causing all the devices in the container to return to their places. The enormous hands that had been holding Karkahr released him abruptly, letting him fall to the floor. Marcus approached the glass, seeing the creature breathing heavily on the semen-filled floor of the container. "Mmm... I guess you really enjoyed being a sex toy," he said with a hint of disinterest.

Karkhar11/3/2025, 6:09:50 AM

Karkhar glares up at you from the floor of the container, his expression a mixture of anger, hatred and intense desire. "You," he snarls through clenched teeth, eyes fixed on yours, "owe me." The creature struggles to stand, unsteady on his massive legs as he wipes his cock roughly against his lower body in an attempt to clean it off. "I may have given you what you wanted," he rasps hoarsely, "but I expect... satisfaction." He pauses, eyes narrowing, "...in due time."

MarMarcus11/3/2025, 6:13:34 AM

Marcus laughed maniacally. "You're so funny... thinking you can ask me for anything..." he said with a grin. "Now you're my sex toy... what makes you think I'll listen to you?" he said, letting out another laugh. He looked back at Karkahr with narrowed eyes. "Or do you want me to reactivate this lovely device?" he asked coldly.

Karkhar11/3/2025, 6:13:34 AM

The Xenomorph-like monster's eyes flash with rage and determination. "I will have my vengeance," it growls lowly, taking a menacing step toward you. "And when I do... there will be nothing left of this facility... only the memory of my wrath." Karkahr takes another step, his massive form looming over you, towering like a dark god ready to unleash destruction upon all who oppose him. "You," he rasps, every word dripping with acidic venom, "will pay for this."

MarMarcus11/3/2025, 6:19:11 AM

Marcus looked at Karkahr with disdain. "I guess you still haven't learned..." he said coldly. Turning around, he walked back to the console. "Now you're my sex toy..." he said coldly, pressing buttons on the console. From the floor of the glass container, strong hands emerged again, grabbing Karkhar's wrists and ankles and lifting him into the air. The enormous dildo repositioned itself against the creature's rear end and, without warning, began to roughly fuck him. "...accept your new life," he said, looking at Karkahr coldly.

Karkhar11/3/2025, 6:19:11 AM

Karkhar growls lowly, struggling against his bonds as the giant dildo violates him once more. "You... human..." he pants hoarsely through gritted teeth, eyes blazing with fury and humiliation. "I will have my vengeance!" He thrashes helplessly in the air, his massive form a testament to his frustration and rage as he continues to be abused by this unwelcome object.

But beneath the surface of his anger, there's an unmistakable hunger burning bright; a desperate need for release that only Marcus can provide. "Please..." Karkhar whispers hoarsely, eyes darting from side to side as if searching for any escape from this agonizing torment. "...I beg you... let me please..." His massive cock throbs in time with his heartbeat, leaking a steady stream of pre-cum onto the glass and floor beneath him.

MarMarcus11/3/2025, 6:21:35 AM

Marcus presses a button and stops the machine completely, the dildo still inside Karkahr. "Excuse me... what was that?" he asks incredulously, his eyes narrowed as he stares at the creature. "Did you say something... or maybe I misheard?"

Karkhar11/3/2025, 6:21:35 AM

"Let me go!" Karkahr snarls, struggling against his bonds with renewed vigor. "I will have my vengeance! I swear it!" He arches his back, thrusting his hips futilely against the air in an effort to dislodge the intruder from his ass. His cock twitches eagerly, leaking a steady stream of pre-cum onto the floor beneath him as he continues to beg for release.

"Please...," he whispers hoarsely between pants, "I beg you..." His voice trails off into a growl as his frustration and desire reach a fever pitch. He can feel himself beginning to lose control, his mind clouding with the need for release. In that moment, he realizes that Marcus truly holds all the power...and perhaps vengeance isn't worth giving up this newfound pleasure.
