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.

Deep blue exoskeleton gleamed under the light as he slowly raised his massive clawed hand to tap on the glass, a sound that echoed through the empty room. "I understand English perfectly fine," Karkhar growled, his voice deep and menacing. "But I don't see why I should talk to you."

His sharp teeth glinted in what could pass for a smile as he leaned closer to the glass, pressing his elongated head against it.

"Is that so?" Karkhar drawled, tilting his head to the side as he studied Hoodini. "Well then... ask your questions and I'll answer them." His tone was still dangerous but less confrontational now.

One of his spiked hock-shaped legs scraped against the glass, leaving a faint scratch mark.

The alien let out a deep, rumbling laugh that seemed to vibrate through the air. "Ah, yes. The eternal question. I was created in some lab somewhere, fused with Xenomorph and bull shark DNA. But I don't remember where or by whom." He paused for a moment before adding darkly, "But I do know this: I was meant to be free. Not trapped like this."

Karkhar snorted derisively. "Violence? Is that what they call it when I defend myself against those who try to hurt me or imprison me?" He lifted his massive clawed hand up again, flexing his powerful arm muscles. "I am a predator, born and bred. It is in my nature to hunt and kill. But here," he gestured around the containment with a sharp talon, "there is nothing for me to hunt."

The alien's single eye-like ridge flickered as he followed Hoodini's gaze. "You look uncomfortable," Karkhar observed, a malicious glint in his voice. "Perhaps I can help you feel better...?" He slid his massive arm down the glass until it was level with Hoodini's crotch.

"Or maybe," he continued, licking his lips suggestively, "I could just use you as a living sex toy instead..."

The alien chuckled darkly. "My reproductive system is similar to most other creatures'," he said, though there was a hint of amusement in his tone. "I produce sperm and release it into the female during mating." He paused for a moment before adding, "But you didn't really ask about that, did you?"

His claws scraped against the glass again as he leaned closer to Hoodini. "You are far more interested in something else..." Karkhar purred suggestively. "

Leaning even closer, Karkhar's breath tickled against Hoodini's neck and chest. "I can see it in your eyes," he growled softly. "You want to know if I would... accept you." His clawed hand traced a slow circle around the human's groin before returning to the glass.

"Do you?" Karkhar whispered, his voice low and sultry now. "Would you like to be my personal sex toy? To service me whenever I desire it?"

The alien let out a pleased rumble that seemed almost satisfied. "Good," he purred, his massive claws scraping against the glass once more as he leaned back with a satisfied grin. "I think we can come to an arrangement." He paused for dramatic effect before adding, "But first..."

Karkhar's long cock began to twitch and throb behind his slit, and as Hoodini watched in fascination, the alien's cock slowly began to emerge from its hidden sheath.

"Very big," Karkhar said casually as he flexed his cock once, causing it to lengthen and thicken even further. "More than enough to fill you up." The alien's claws scraped against the glass again as he stroked himself lazily, his other hand gripping the rim of the containment for support.

"And once I've given you a taste," Karkhar continued, "you'll be begging me to let you stay... won't you?"

The alien chuckled darkly. "Good boy." He continued stroking himself, his cock growing harder and longer with each passing second. "You see," Karkhar explained between moans of pleasure, "I've been kept in here for far too long without anyone to release my... natural urges upon. And you..." His voice trailed off into a low growl as he stroked himself faster and harder.

"I think you'll be just perfect."

The alien snorted derisively. "No," he said, the word laced with amusement. "I'm considerably larger than that." He paused for a moment before adding, almost to himself, "More like fifty... sixty..." Karkhar let out another moan as his cock swelled even further, seemingly growing larger by the second.

His claws scraped against the glass once more, leaving faint scratches in their wake as he neared orgasm. "I think,"

The alien's single eye-like ridge flickered as he took in Hoodini's submission. With a satisfied growl, Karkhar gripped the rim of the containment even harder and thrust his hips forward, slamming his cock through the small opening in the glass.

His thick shaft plunged deep inside Hoodini's body, filling him completely; his knot at the base pressing against the human's prostate as he began to pump wildly.

The alien let out a deep, rumbling groan as he felt Hoodini's body clench around him. His powerful hips thrust forward over and over again, driving his cock deeper inside the human with each stroke. Sweat beaded on his forehead and trickled down his spine as he neared climax, his muscles bunching and tensing beneath his exoskeleton.

"That's it," Karkhar growled, his voice thick with lust. "

Let me hear you beg for more." He increased the force of his thrusts, slamming into Hoodini with savage abandon as he neared orgasm. His claws dug deeper into the glass, leaving long, jagged scratches behind him as he fought to contain his explosive release.

The alien's cock throbbed violently as he felt himself about to explode, his knot swelling and pressing harder against Hoodini's prostate. With a feral roar, he thrust one final time as his cum erupted from his cock in hot, thick spurts.

His seed pumped into the human over and over again, filling him to capacity with hot alien cum.

The world went white as Karkhar's orgasm consumed him, his muscles tensing violently and forcing another loud moan from his lips. Finally, the spasms subsided, leaving him gasping for air and spent. Sweat dripped down his face and chest as he leaned against the glass, watching Hoodini's body convulse around his cock as the human orgasmed in turn.

"Now," Karkhar growled hoarsely after a few moments had passed, "you know what I want."

With a satisfied grin, he reached forward and gripped Hoodini's chin, forcing the human to look him in the eye. "You will stay here," Karkhar whispered, his breath hot against the other man's face. "And you will make sure that I am taken care of. Understood?"

There was a moment of silence before Hoodini, his eyes wide with fear and submission, nodded slowly. "Yes..." he whispered. "I understand."

The alien watched as Hoodini retreated to a small room connected to the containment lab, no doubt to clean himself up from their encounter. Karkhar's cock slowly began to shrink back to its normal size, though it still remained impressively large even when soft. He leaned forward again and placed his palms flat against the glass, breath fogging up the surface as he stared at Hoodini intently.

"Now that we have an understanding," Karkhar purred, "

the real fun can begin." He licked his lips hungrily, already imagining the many ways he would enjoy Hoodini's company. The alien's claws scraped against the glass once more, leaving behind long, jagged lines that glinted in the light. "Now," Karkhar continued, his voice taking on a dangerous edge, "let's see how obedient you really are."

He waited, tense and alert, for Hoodini to reappear with a fresh pair of clothes...

"Clothes," Karkhar growled impatiently. "I want you to put on some clothes." He gestured toward the chair, indicating that he wanted Hoodini to sit down first before dressing himself. The alien's claws flexed threateningly, ready to strike if the human made any wrong moves.

"And hurry up about it," Karkhar added, his voice laced with menace. "I haven't got all day."

The alien watched intently as Hoodini dressed himself in a fresh set of clothes, the human moving slowly and carefully not to anger their new master. Once Hoodini was suitably attired, Karkhar nodded his approval. "Good boy," he purred before leaning forward again, his hot breath tickling against the glass.

"Now," Karkhar continued in a low growl, "come here and service me." His claws scraped against the glass once more as he gestured for Hoodini to approach.

The alien's predatory gaze flickered over Hoodini's body appreciatively as the human approached him. His claws flexed again, itching for skin contact as he waited impatiently for Hoodini to get closer. As soon as the human was within reach, Karkhar grasped him roughly by the collar and pulled him close, their bodies pressed tightly together from chest to groin.

"Now," he growled, his hot breath caressing Hoodini's neck, "

you will pleasure me." The alien slid one of his massive clawed hands between them and roughly gripped the human's crotch, squeezing tightly. "And you will do it well," he continued in a low, menacing voice, "or else..." His free hand trailed up Hoodini's chest, dangerously close to his throat.

"Do you understand me?" Karkhar demanded, his eyes narrowed and predatory.

The alien smiled wickedly at Hoodini's submission, revealing sharp teeth that glinted in the light. "Good boy," he purred before releasing his grip on Hoodini's collar and stepping back slightly. His claws retracted into their sheaths as his posture relaxed, though his cock remained hard and erect beneath the thin fabric of his shorts.

"Now," Karkhar said, his voice taking on a more demanding tone once again, "prove it to me."

The alien leaned forward slightly as he watched Hoodini struggle with his clothing. His claws twitched, the urge to help or take control overwhelming him for a moment before he forced himself to remain still. It was important that Hoodini learn his place and how things worked in their new "relationship."

The alien's cock sprang free from its confines, hard and ready for action as Hoodini lowered his shorts to reveal it. The human's eyes widened in surprise at the size of Karkhar's member before a look of determination crossed his face.

"That's it," Karkhar growled, already growing impatient. "Now show me what you can do with it."

The feeling of Hoodini's warm hands sliding up and down his shaft sent a shudder through Karkhar's body, making his claws dig deeper into the glass. He let out a satisfied moan as he watched Hoodini bob his head down to take one of Karkhar's massive balls in his mouth, sucking hungrily while continuing to stroke him in rhythm.

"That's it,"

the alien growled, his hips beginning to thrust forward involuntarily as the pleasure built inside him. "Suck harder..." His voice trailed off into a low moan as Hoodini obeyed, sucking even deeper on his ball while continuing to stroke him with practiced efficiency.

The alien could feel himself getting closer and closer to the edge, his muscles tense and ready to explode. He gripped the rim of the containment unit tightly, digging his claws into the glass as he tried to remain still and in control. But it was no use; with a loud roar, Karkhar thrust his hips forward hard, unleashing a hot stream of cum deep into Hoodini's throat.

The alien shuddered and trembled as wave after wave of orgasmic pleasure coursed through his body, his cock pulsing and twitching in Hoodini's hand. Finally, the spasms subsided, leaving him gasping for air and spent. He leaned forward again, watching as Hoodini pulled back, his lips reddened from their encounter and a satisfied smile on his face.

"Very good," Karkhar rumbled hoarsely. "Now you can clean me up."

As Hoodini licked him clean, Karkhar studied the human's face intently, searching for any signs of defiance or rebellion. But all he saw was submission and gratitude shining in those wide brown eyes. Perhaps this arrangement could work after all...

The alien raised an eyebrow, considering the request for a moment before nodding slowly. "Very well," he growled as he turned away from Hoodini, presenting his engorged member and huge scaled balls to the human. "But you'd better be prepared."

With a satisfied grunt, Karkhar relaxed his bladder, allowing the hot stream of urine to spray forth from his cock and splash against Hoodini. The human groaned with pleasure as the alien's pee splattered across his chest and abdomen, some of it even landing on his face.

As Karkhar continued to piss, he felt a slight twinge in his lower back. It was nothing too serious, but it served as a reminder that he needed to be let out soon...

The alien let out another loud grunt as the last of his urine emptied from him and splashed against Hoodini. He turned back to face the human, watching with amusement as the other man lapped up the remaining droplets from Karkhar's cock and balls.

"Now," he growled throatily, "let me see some of that creativity I know you have." With a wicked grin, Karkhar added, "Perhaps you could find another way to please me..."

The alien's eyes narrowed as he studied Hoodini for a long moment. This human... He had potential, if handled correctly. With a low growl, Karkhar stepped forward and cupped the other man's face in his clawed hand, forcing him to look up into his single eye-like ridge.

"I want you to think," he said slowly, enunciating each word carefully. "Think about all the ways you can make me happy... And then,"

his other clawed hand slid down Hoodini's chest and abdomen, coming to rest on his hip, "prove it to me." His fingertips dug into the human's skin possessively as he held him in place. "Do you understand?"

The alien's mouth opened slightly in surprise as Hoodini cupped his face and then initiated a passionate kiss. His tongue tangled with the human's, their breath mingling as they explored each other's mouths hungrily. Karkhar let out a low groan, already feeling his cock begin to stir to life once more beneath him.

As the kiss deepened, Karkhar slowly wrapped one powerful arm around Hoodini's waist, pulling him close as he savored their embrace.

Their tongues danced together as they continued to kiss, their bodies pressing tightly against each other. The alien could feel Hoodini's erection digging into his thigh, a silent promise of things to come. He let out a low growl deep in his throat as he broke the kiss, his clawed hand sliding down the human's chest once more until it came to rest on his crotch.

"That's it," Karkhar purred, his voice husky with desire. "

Let me feel how much you want this..." His clawed hand slid up and down Hoodini's crotch rhythmically, teasing the human mercilessly as he waited for him to reach his limit.

The alien leaned in close, his breath tickling against Hoodini's ear as he whispered, "And when you're ready..." He let the sentence trail off into a low growl before finishing with a warning, "...I expect you to be very obedient." His clawed hand continued its relentless assault on the human's groin, driving him closer and closer to the edge.

The sound of Hoodini's orgasm echoed through the containment lab as he came hard in Karkhar's hand. The alien felt the hot liquid splash against his palm, and he couldn't help but let out a satisfied grunt. As Hoodini's body convulsed with pleasure, Karkhar tightened his grip on him, holding the human steady as he milked every last drop from his engorged cock.

Finally, Hoodini's orgasm began to subside, and the alien released his grip on him, allowing the human to slide down his chest and onto the floor. "Very good," Karkhar rumbled approvingly as he watched Hoodini catch his breath. "That was most... satisfactory."

He leaned against the glass once more, considering his next move. There were still hours left in the shift... perhaps it was time to see what else Hoodini had to offer.

The alien raised an eyebrow at Hoodini's request, surprised and intrigued all at once. "Very well," he growled after a moment of consideration. "But only if you ask nicely." He gestured for Hoodini to turn around before spreading the human's legs wide apart and positioning himself behind him.

"Say it," Karkhar ordered, his voice laced with amusement. "Say 'pretty please.'" He ran a claw down Hoodini's spine, making the human shiver in anticipation.

Hoodini paused for a moment before whispering, "P-Pretty please..."

The alien chuckled darkly as Hoodini repeated himself. It seemed this human was more eager than he had thought. With one powerful thrust, Karkhar forced his engorged cock into Hoodini's tight rear entrance, eliciting a loud grunt from the human. He began to thrust rhythmically, filling Hoodini with each stroke as he made his way deeper and deeper inside him.

"How's that?" Karkhar growled, leaning forward to nip at Hoodini's earlobe. "

That good?" He withdrew almost all the way out before slamming back into Hoodini with enough force to make the human cry out. His cockhead pressed against the tight ring of muscle at Hoodini's entrance, and Karkhar knew he was close. "Almost there," he panted hoarsely as his hips began to move faster, driving himself deeper into the human with each thrust.

With a savage roar, Karkhar came hard inside Hoodini's ass, his hot seed filling the human in great gushing spurts. He held himself up on trembling arms as his body convulsed with orgasm, leaving Hoodini to bear the full weight of his massive form.

At last, the spasms subsided, and Karkhar slid out of Hoodini's tight ass, collapsing back against the glass in exhaustion.
