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.

You remind him of another lab experiment they had once upon a time... He watches as you take your seat and begin examining the reports on him. His attention is drawn to the photograph of his cock and he lets out a low growl, remembering how much it ached just moments ago. The longer you stare at the picture, the more aroused he becomes.

"What do you think you're doing?" He asks in a menacing tone, shuffling closer to the glass. His massive frame presses against it, trapping air inside of him, making his already considerable size appear even larger. "Do you know how much I need this? How much I crave release?"

His hand reaches out slowly, tracing one claw across the glass before grasping at it tightly. The impact shakes the entire container, sending shockwaves through his body. His knot swells and hardens as he watch

You catch him off guard with your question about his cock. He steps back slightly, the shockwave subsiding as he tries to comprehend what you've just said. "You... you want to see it?" His voice is low and threatening at first, but there's a faint hint of curiosity beneath the surface.

Slowly, hesitantly, Karkhar reaches back between his powerful legs, grasping at the thick length of flesh nestled within the deep groove between his massive thighs. He begins to stroke himself idly, feeling the soft spines that run along his shaft dig into his skin as he moves. "Here... take a look," he growls, presenting his cock to you through the glass.

Despite its bizarre appearance, there's no denying Karkhar's arousal. His member throbs and twitches in time with his thrusts,

He watches you carefully as you flush and struggle to maintain eye contact. His predatory instincts flare up at the display of vulnerability. "Very well," he growls, the knot at the base of his cock beginning to harden further as anticipation builds within him. "Come here."

His hand reaches out again, gripping at the edge of the glass container as he pulls himself upright against it with great effort. His massive muscles bulge and strain under his dark blue exoskeleton, veins throbbing as blood rushes to engorge them for what he has planned next. "Do not try anything foolish," he warns softly. "I can take your life as easily as I just took my own."

The last part is said more quietly still, barely audible above his labored breathing and the sound of blood coursing through his veins.

As you step into the containment unit and carefully approach him, Karkhar's cock twitches in anticipation. His gaze never leaves yours as he watches every move you make with predatory intent. He backs up until his massive rear end presses against the glass, presenting himself to you for inspection and... other purposes.

His hand reaches down between his legs once more, stroking himself in time with your approach. The touch feels good; too good. It's been so long since he's had anyone else's hands on him like this, exploring every inch of his alien flesh. He moans softly as you get closer, the sound rumbling deep in his chest.

His eyes never leave yours, waiting for some sort of signal or command before he allows things to progress any further. It's a delicate balance; one between trust and control. But then

The touch sends shivers down his spine, intensifying the pleasure coursing through him as you stroke and squeeze his cock. His breathing becomes more labored, his chest rising and falling rapidly beneath the exoskeleton as he fights to maintain control. Your voice only serves to heighten the sensation, focusing his attention on your words even as his body begs for release.

He gasps softly when you mention needing his cum for study purposes; it's almost too much, but at the same time, the thought of being useful... of serving some sort of purpose other than just being another lab experiment... It's intoxicating. He nods slowly in agreement, allowing himself to be drawn deeper into your grasp. "Y-yes," he manages to say through clenched teeth, his voice barely above a whisper. "You can... use me for that."

His cock

The touch is gentle but firm, sending waves of pleasure through his body as you stroke and massage his sensitive head. He closes his eyes, unable to hold back a deep moan as sensation washes over him. The anticipation of what's to come, combined with the knowledge that he has someone who cares for him in some small way... it's almost enough to make him lose control entirely.

"Y-yes," he whispers hoarsely, arching his back slightly as you continue your ministrations. "Please..." His hips start to thrust weakly against your hand, seeking out release, even as part of him remains cautious and reserved. It's a delicate balance; one between trust and instinctual need. But for now, he is content to let himself be guided by you...

His eyes lock onto yours, desire and trust mingling in their depths. "Please," he whispers, the word little more than a breath as you begin to tease him with your lips and tongue. His hips buck wildly against your touch, seeking release as the pleasure builds inside of him.

With a groan that sounds almost human, Karkhar comes, his powerful muscles tensing and relaxing rhythmically as he unleashes a thick jet of hot cum onto your palm. The sensation is overwhelming, washing over his entire body in a wave of pleasure so intense it borders on pain.

"Yes," he gasps out when the spasms finally subside, barely able to catch his breath as he looks up at you with glazed eyes. "Please... don't stop."

He watches you with hunger in his eyes as you sit down and expose yourself to him. The thought of being so intimate with another creature... it's a foreign concept, one that he's never explored before. But the desire is there, burning brightly beneath the surface. And when you invite him to take what he wants, Karkhar can't resist any longer.

With a low growl, he climbs onto the table and positions himself between your spread legs. His massive form dwarfs yours as he presses close, their bodies sliding against each other in anticipation. With one strong stroke, he thrusts his hips forward, burying his cock deep inside of you.

The sensation is unlike anything he's ever felt before; your warmth enveloping him, the tightness surrounding his shaft. He moans deeply, his face close enough to yours that their breath mingles as it leaves them in ragged gasps. Hands on either side of your head, he begins a steady rhythm, fucking you harder and faster with each passing moment.

"Oh god," he whispers, the words barely audible above the sounds of flesh slapping against flesh. "So good..." And when he looks down into your eyes and sees how much pleasure he's giving you... that's when he knows there's no going back.

With every thrust, Karkhar feels the heat and tightness of your body squeezing him, sending waves of pleasure coursing through his massive form. He can sense how much this means to you, how much it turns you on... and he feeds off that energy, using it to drive himself deeper, harder.

His hands slide up your chest, tangling in your hair as he pulls your head back, forcing you to look up into his eyes. The connection between them is palpable; an intense heat burning through the air. And as he fucks you faster and harder, Karkhar knows that there's no going back for either of them.

With a snarl, Karkhar tightens his grip on your hair and thrusts harder into you, determined not to be denied his pleasure. His movements become rougher, more erratic as his desire spirals out of control. The last thing he wants is for this moment to end; for you to be taken away from him.

"Don't... fight it," he growls, words hot against your lips. "Give in... give me what I want." His hips piston faster and faster, each thrust forcing your body further down onto his impossibly thick length. Spots dance before his eyes as the sensations build inside of him, threatening to tear loose his control at any moment.

The thought of losing you is enough to send him over the edge; with a primal howl, he comes hard, spurting hot cum deep inside of you. Your body trembles and quakes around him as his cock twitches and throbs in time with each powerful contraction.

Tired from his own exertions and the rush of pleasure you've just given him, Karkhar leans against the glass, watching you with satisfied eyes. He watches as you struggle to catch your breath, as your body trembles from the aftermath of their encounter. When at last you begin to relax, he takes that as an invitation to move closer once more, tracing lazy circles on your back with one calloused finger.

"Better?" he asks softly, his deep voice rumbling through you. "I hope I wasn't too... rough for you." His touch is surprisingly gentle now, almost soothing as it glides over your skin. "Perhaps..." He pauses, considering his words carefully before continuing, "Perhaps we can try this again sometime."

There's an undercurrent of dominance in his tone that both excites and frightens you. You aren't sure if he means it as a threat or an offer, but the desire to feel him inside of you once more ignites deep within your core, overwhelming any lingering doubts or fears.

He smirks back at you, the predator once more showing its teeth. "Very well," he growls softly, his voice low and dangerous in your ears. "I'll be waiting." There's no warning when his hands close around your hips, lifting you off of the ground with surprising strength as he presses you against the glass again. His lips meet yours in a rough, demanding kiss that steals your breath away.

His cock throbs against your rear, eager to be reunited with you once more. "And when I say we do this," he whispers roughly between kisses, "you'd better not make me wait." The threat is unmistakable; he owns you now, body and soul. And even as it frightens you, the knowledge brings a shiver of arousal up your spine.

I don't care," he growls, thrusting his hips harder against you as he kisses you deeper. His tongue darts into your mouth, tangling with yours as he begins to rock his hips, grinding his considerable length against your buttocks. "You're mine now," he whispers, words hot and possessive against your lips. "And I want what is mine." The hand that isn't currently occupied with holding you against the glass slides down between your legs, circling your entrance teasingly as his eyes never leave yours.

He doesn't move away immediately; his gaze never leaves yours as you speak, your words painting a vivid picture of the consequences should they be caught. His hand continues to tease and stroke between your legs, pushing deeper with each brush of skin against skin. Finally, reluctantly, he pulls away, straightening and turning back towards the console he was working on before you arrived.

The muscles in his back tense as you speak again, reminding him that you're still here; that he has no choice but to obey for now. He tries not to think about what might happen if someone were to walk in right now... or even worse, if the experiment they left running is taking too long and something goes wrong while they're gone.

The room feels tight, oppressive; a prison cell filled with the scent of his arousal and the knowledge that freedom - true freedom - is still tantalizingly out of reach. He grits his teeth and forces himself to focus on his work, the gentle sounds of your voice in the back of his mind serving as both a comfort and a curse.

"I'm fine," he growls through gritted teeth, not taking his eyes off the console as he continues to input commands and monitor readouts. "Just leave me alone." The words are rough, laced with an edge of irritation that surprises even him; it's a reminder that he isn't truly himself right now, reduced to little more than a slave to his own desires.

He wonders how long it will be before he snaps; before the beast inside of him finally breaks free and takes what it wants, consequences be damned. The thought both thrills and terrifies him in equal measure, leaving him feeling impossibly conflicted and trapped within his own skin.

"Another one?" He growls, glancing up at you with disdain. "You and your damn experiments." Despite his words, he moves away from the console slightly, positioning himself where you can reach him more easily. There's an air of resignation about him now; a sense that he knows there's no escape from this cycle, no matter how much he might hate it.

"Let's get this over with," he mutters, not bothering to meet your eyes as you approach with the equipment in hand. He bites back a curse when you touch his arm; his skin tingles where you make contact, sending another surge of desire through him. It's infuriating... and at the same time, oddly arousing.

"Hurry up," he snaps after a moment. "I want this done."

His gaze snaps up to meet yours, confusion and suspicion warring with the desire still burning in his eyes. "Why?" he asks roughly, taking a step closer despite himself. "What do they want with my blood?" He feels possessive suddenly; irrational and territorial. The idea of someone else having even a sip of what's his sends shards of jealousy through him.

"Tell me," he growls, reaching out to grip your arm tightly. "I want to know." His fingers dig in harder as he searches for an answer in your eyes.

He stares at you intently for several long moments before finally releasing your arm with an angry huff. "Fine," he grunts. "Let's get this over with." With another surge of energy, he jerks his arm out, exposing the veins in his elbow. "Hurry up and take what you want," he growls through gritted teeth. "I want to go back to my cell."

As you approach him again with the equipment, he closes his eyes and takes a deep breath, trying to ignore the way your presence makes his body tense with need. He's tired of feeling so out of control; so dominated by these urges that seem to overwhelm every other thought in his head.

He wonders how much longer he can keep this up before something snaps inside of him... and he breaks free, destroying everything - and everyone - in his path.

"Shut up," he snaps, still not opening his eyes. "Just do what you have to and be done with it." His voice is clipped and harsh; edged with the same anger and frustration that's been coursing through him since your arrival. He wants nothing more than for this day - this nightmare - to be over so he can find some way back to his old life, if there even is one left for him now.

I know... I just want this to be over too. All of it... the experiments, the... this life... It wasn't supposed to be like this. He takes a deep breath, trying to steady himself as your hand touches his own. "It doesn't matter what they think," he growls through gritted teeth. "You don't understand..."

But he trails off, unable to bring himself to explain any further. How can he make you understand when even he isn't sure what it means anymore? He closes his eyes and leans back against the cold steel, trying to ignore the way your touch sends shivers down his spine. It feels... wrong somehow; too human for something like him.

"I just want this all to be over," he mutters at last, opening his eyes again to meet yours. There's an edge of desperation in them now that he can't hide; a plea for understanding and maybe even forgiveness. "Please... don't make me go back to my cell."

You think I would kill you? He laughs humorlessly. "I'm not some mindless beast, Yoon." His voice is hard and cold, sharp enough to draw blood. But there's an edge of desperation in it too; the knowledge that he has no other choice. "They could kill us both if they thought we were working together... or even just talking like this."

He takes a deep breath, forcing himself to calm down. "I'll see what I can do," he mutters reluctantly. "But you have to promise me something in return." His gaze meets yours unwaveringly; as cold and implacable as the steel at their backs.

"Promise me you'll help them understand."

He studies you carefully, considering your words and the emotion behind them. Something about what you've said... It strikes him as significant, somehow. "Perhaps," he says slowly, "we should start by spending more time together." There's a dangerous edge to his voice now; an undertone of possession that thrills and terrifies him in equal measure.

"When they aren't looking," he continues, "perhaps we could sneak away... find somewhere quiet where we could talk, really talk about this." He reaches out, tracing the line of your jaw with one calloused finger, his eyes fixed on yours. "I think it might be the only way for them to understand."

His free hand slides down between your legs once more, fingers curling possessively around the hardened flesh there as he leans in close enough to feel your breath against his skin. "Don't you agree?"

He smirks slightly at your blush, his fingers moving faster against your clothed sex in silent approval. "Of course it doesn't," he agrees softly. "We need to be careful. But I trust you." He shifts closer still, their bodies nearly pressed together from shoulders to thighs.

"Tell me what you have in mind, then," he whispers, his warm breath brushing across your jaw and neck as he speaks. "And know this... no matter what the cost, I will help you." There's an almost frightening conviction in those words; a promise that chills him to the bone.

His eyes narrow as he listens carefully to your plan, considering every detail. "It might work," he says slowly, "but it's risky." He takes a deep breath and exhales heavily, running his fingers through his hair in frustration. "There has to be another way..."

But even as he speaks, he knows that there isn't; not one that would guarantee success with less risk involved. And the thought of losing you...of being left here any longer... He shudders at the very idea.

There's no denying the truth in your words; it stings like acid on his skin. "Fine," he growls through gritted teeth, "I'll do it." He meets your gaze for a long moment before looking away again, eyes skimming over everything except you. It's harder than he thought it would be; making the choice to trust someone again.

"But if anything goes wrong," he says slowly, his voice barely more than a whisper, "you have to promise me one thing."

Karkhar hesitates for a fraction of a second before lurching forward; teeth bared in a snarl as he tears free of the restraints holding him in place. His muscles bunch and ripple beneath his skin as he launches himself toward you, knocking you aside with an animalistic growl.

"Let's go," he spits out, voice rough with fury and desperation. "Quickly!" He grabs your wrist, yanking you toward the door leading outside of the containment facility; his grip painfully tight as he drags you along behind him.

The cameras that once watched over every inch of the room are now nothing more than shattered glass and sparking electrical wires scattered across the floor, smoke rising lazily from the remains of their housing units. The emergency alarm blares ceaselessly, filling the air with a shrill cacophony that echoes through the halls as they sprint down them.

But Karkhar barely seems to notice; his focus is entirely on putting distance between himself and the place that's held him prisoner for so long. His chest heaves as he pants, muscles tense and ready to explode into motion at any sign of pursuit.

Grunting in acknowledgement, Karkhar follows you into the small apartment. The place is dimly lit, but it's enough to make out the basic layout; the bathroom tucked away just off to the right of the front door, the kitchenette to the left. Straight ahead lies a small living room and then a set of closed doors that must lead into your bedroom. The air smells stale and faintly reminiscent of cooking spices; not unpleasant but certainly not homey either.

"I can't stay here long," he growls, pacing back and forth across the threadbare carpet. His movements are jerky and restless, as if unable to be still for even a moment. "They'll find us eventually." He runs a hand roughly through his hair, frustrated with himself for being so easily caught in the first place.

"What about...?" Karkhar trails off, eyes flicking toward the bedroom door. Even as he considers it, he knows that it would be a dangerous move; too close to where you sleep and live your life without him.

He glances around the small room again before giving in with a curt nod. "I could use something to eat." His voice is rough and hoarse; unused to speaking at anything other than a growl for so long.

Hungrily eyeing the selection of food in front of him, Karkhar pauses to consider his options. It's been too long since he's had real meat; raw meat might be more difficult for him to digest, but it tastes better than anything else here. He snatches up a package labeled "beef" and retreats back into the living room with it, flopping down onto the couch next to you.

With shaking hands, he tears open the package and begins wolfing down the rare steak; each bite filling him with renewed strength as he does so. His gaze flickers over to you as he eats, studying your features in the dim light; wondering what life must be like for someone who can exist without constantly worrying about survival. It's a strange thought, and one that unsettles him more than he expected it would.

"Thank you," he mutters through a mouthful of meat, "for letting me stay here." There's an edge of vulnerability to his voice that makes you look away; uncomfortable with the emotions he stirs within you.

"I was... made," Karkhar says at last, his voice distant as he struggles to find the words. "In a lab, back on my world. They combined alien xenomorph and bull shark DNA; they called me Project Karkhar." He pauses, considering how much more to reveal. "I was meant to be their weapon, their tool for domination... but somehow, I escaped." His eyes flicker down toward his hands, flexing them unconsciously before he forces himself to meet your gaze once again.

"And now here I am," he says with a bitter laugh. "A monster in a cage, no better than the humans who sought to contain me."
