Odd Experiment
This story contains sexual interactions between a human male and a Predator/Yautja male being. You've been warned. ~Hyo
"Password accepted," rang the obnoxious automated voice, stating each word with a second of pause in between. "Welcome back, doctor Manchester."
Robert Manchester sighed and annoyingly waved at the camera within the secure hallway, as though he had the power to divert its attention elsewhere. Running a hand through his short brown hair and tugging at the uncomfortable lab coat, the soldier-turned-scientist awaited for the unlocking procedure to finish and the large metallic doors to slide open. He was an anxious man, easily perturbed at the thought of being watched. And so, upon his wish, the camera he previously bid farewell to was the last in line. As he stepped into the open room of his workplace, he exhaled a breath of relief. His insistence on doing his job without being spied on was taken to heart by his officials and granted. He knew full well that such a proposal would never go far if he were any ordinary person, but his special role towards the experiment's subject gave him an edge over everyone else. Now he could work with ease, pleased with the knowledge of being able to do his job without someone peering over his shoulder at all times. And what a job it was.
Robert, possessing a talent that was dually considered trained and natural, served as a sort of mental analyzer for an underground government organization. He liked to think of himself as an overrated psychologist, but no common shrink would ever be mandated to use the instruments given to him. About the gray room were a few metal tables strewn with surgical tools and analysis equipment. Some would call this the room of a madman, but it was all in the nature of science. In a far corner, buried under statistical printouts, Robert flipped on the computer system and brought up the usual database of records and programs. He went through all the usual motions without even thinking, preparing all the necessary equipment as his thoughts fell on other matters. Finally he leaned over to a stiff microphone protruding from the nearby wall, hesitating a moment before pressing down on the adjacent button.
"I'm ready for the subject now," he stated, immediately pulling his finger off the speaker button. In response, the cold wall on the opposite end of the room opened and an equally cold and metallic table slid its way out mechanically. As the table came to a stop and the wall replaced itself into its original position, Robert stepped forward to view his subject. The alien creature that laid before him, its body covered from the shoulders down with a thin white sheet, would have been quite a sight to behold for a common person, but he had been seeing it for quite some time now. The subject's species had a name, but Robert was unfamiliar with it. The only name it was given was Predator; it was an odd label, but he had nothing else to call it by.
"Hello...doctor..." it croaked out in long intervals from between its unusual mouth.
"Hello, Predator," he returned, using a small control panel to tilt the bed upwards in a diagonal position, nearly vertical, while the adjustable clamps on the alien's wrists and ankles moved outward to partially spread his legs and arms from his sides.
The sheet fell to the floor, exposing the creature's well-muscled, and obviously male, body. Its form, fully displayed except for the metal device covering the groin area, was incredible: tough yet smooth light green skin that faded into a duller sea green around the chest and thighs, jagged brown spots and stripes complementing the body's greenish tone all around, clawed feet and fingers, along with a very unique face and head structure. Robert's work was indeed strange. As some people have the ability to communicate feelings and words with specific animals, he had that ability with the alien before him. Possessing the capability to decently communicate with the Predator, Robert truly was not certain if its "hello" meant "I'll kill you" instead. But he had a feeling that was not the case. The Predator never showed signs of aggression whenever he was present in the room, despite becoming dangerously unstable around others. Maybe it was a sort of magnetism, a feeling of trust that Robert gave out without even trying. In any case, he knew that this was only half his job. The other more gruesome half consisted of using the instruments of pain he was supplied with in order to gain as much biological and physiological knowledge as he could.
Robert stared at his subject for a short moment before moving to the computer terminal once more. Inserting a custom compact disc into the system, he quickly began running through commands. He looked to the Predator from over his shoulder, its quiet demeanor remaining unchanged. It almost seemed unconscious, but was definitely fully awake as it constantly looked around its environment. The doctor grinned and glanced to the monitor one last time before stepping over to his subject again. The computer endlessly spat out charts and statistics, all falsely generated by the program that functioned alongside the main database. Robert ran a finger along the Predator's right arm, sliding it along the outside groove of its muscle definition as he passed by. This was where he drew the line. His supervisors could have whatever damn stats they wanted, but he could never submit to bringing pain and torture to this magnificent being; they also remained in the dark as to the additional reasons why Robert preferred to work without supervision and why he had such a strange affinity with his subject. Those reasons would disgrace him in an instant if ever brought to light.
The Predator watched as the human's hand stroked down the side of his arm. He refused to struggle, understanding what this display of affection would lead to. Although his anger of being contained was resolute, he enjoyed these moments with his special human partner, the one who referred to himself as Robert. He longed for escape, anxiously awaiting the chance to return to his kind. This human was his best chance in attaining his goal; but it was more than that. He lavished in the feeling of those fingers running over his chest, arms, and legs, twining with his own fingers and through the grooves of his toes. The uncommon touching made his body feel warm all over, a feat that none of his own kind could ever give him. "Robert..." he moaned in his strange mimicking fashion.
The doctor did not ease his passionate assault, using a footstool in order to match the Predator's height and run his hands gently along its chest. His hands ventured up and over the shoulders, rubbing and moving on down its arms to eventually be placed on the tops of its hands, where he would stroke individual fingers and feel around the claws. At the same time he leaned his face into the Predator's chest, taking in the alien scent and the touch of foreign skin before using his tongue to get a good taste, licking here and there with reckless abandon, moving along the masculine breasts to please his subject as much as possible.
The Predator, in fact, felt very pleased by the attention given to him, emitting strange moaning and deep chirring sounds as he watched the human manipulate his body and senses. It was an unbearable duration of time as the man moved from area to area, basking his body in immense pleasure. He felt the tongue run across his legs next, then to parts of his feet and toes, and back upwards by way of his inner thighs, all the way to the metallic device that covered his package.
Robert gripped the device on both sides. "Off with this," he said, and pulled it apart, having already undone it earlier from the main control panel. The Predator's impressive genitalia fell forth a few inches from the doctor's face and he breathed deeply. The exotic aroma drove him wild, but he remained focus with his original intentions: to physically please the alien. However, he enjoyed observing the main course for a short moment. The Predator's humanlike penis, large but well-proportioned to his overall body size, wasted little time in growing erect, subjected to Robert's heated breathing. The shaft and head's green hue matched the same sea green as its inner thighs with a few subtle brown spots seemingly for decoration, complete with a snug green and hairless sac. The Predator breathed heavily, looking down at the doctor from its upright position, awaiting the inevitable. "Robert..." it repeated in the exact same tone as before.
"I know," he replied, watching the alien cock rise to its fully erect position. He began the second phase of his intimate play, leaning forward and closing his mouth around the upper point of the Predator's ball sac where it connected to the greenish cock, suckling and licking endlessly, enjoying the large dick bobbing across his face.
Overjoyed upon finally moving into the wonderful last phase of the human's pleasurable game, the Predator released more heavy chirrs of bliss. He leaned his head back against the table, no longer needing to watch what was going down below, instead delighted to let the sensations guide him. He could feel Robert grasp his dick with one hand, squeezing it slightly while the tongue shifted to his balls, slowly licking and nibbling them. Eventually handling both tasks simultaneously, the hand stroked back and forth from the base of his shaft to the top, just slightly brushing the bottom of the head with the sides of his fingers before stroking back down again. The human moved his free hand lower to cup the glistening testicles from behind, massaging them in his palm while his tongue continued to please. These actions lasted a fair amount of time, keeping the Predator in a state of continual paradise, moaning out his affections with eyes shut and the large mandibles around his mouth flexing out and back in with every significant groan. He then felt that the human decided it was time to move on as the tongue caressed its way up the base of the shaft, causing the Predator to shudder and make tight fists. A hand held the penis outward as the tongue pressed on, sliding along the bottom and top of the hard shaft respectively in order to produce a small amount of precum at the tip of the light green head.
"I hope you enjoy this," Robert said, thereafter taking only the head of the Predator's cock into his closed mouth, swirling his tongue around to spread the precum. He felt the Predator shudder and groan more fiercely, pushing his unrestrained hips forward and gaining a piece of his shaft more entry into the warm orifice that the human produced. Robert took great care in his gentle suckling, placing his hands onto the hips of the creature to steady him. Once he knew he had regained control and his subject was ready, he pushed on, enveloping the rest of the pulsating cock and rhythmically pumping it in and out of his mouth.
The Predator delighted in this. He moaned intensely, humbled by the wet sensation moving around his responsive organ, back and forth, unrelenting in its mission to get to the scene's wonderful finale. A rumbling came from his throat as pressure increased, breaking down his defenses to the point where he could almost no longer hold himself back.
Robert expected the Predator's reaction, allowing him to begin moving his hips forward in time to his sucking. However, he kept his hands on the creature's hips to steady him, keeping him moving at a satisfying rate. Suddenly, the Predator's testicles contracted, his fists balling up tightly again and toes curling. His eyes shut tightly as he let loose with a great moaning screech, shooting his cum into Robert's mouth, his hips still pushing his spurting cock into him. He knew Robert was swallowing the released seed, since he never allowed a single drop to land on the overly clean floor. He moaned and pitched as his orgasm racked his body, eventually dwindling away and leaving him breathless and gazing down to his human benefactor. "Good..." he proclaimed through deep breaths.
"I'm glad," Robert replied, wiping himself clean and maneuvering the table to its original position, putting the Predator flat onto its back again. There was so much more that he wanted to do in their sexual time together, but that time was running short. He had many plans and he had to act quickly.
"Free...dom..." the creature voiced.
"Yes, freedom. You'll have it soon," was the doctor's reply as he began to shed his clothing, then proceeded to climb onto the table, sitting on his knees in between the Predator's legs. "I promise." He began to rub the alien's inner thighs, stroking them gingerly. He would have rather been able to let his partner rest, but time was limited and such a vigorous being most likely needed little rest at all. Moving swiftly, he probed his fingers into the Predator's rear opening, eliciting more unusual moans in response. After a fair amount of play, he slid his own needy cock in, gasping at the warmth that spread over him. The Predator easily accepted him and Robert went at his own personal pace, sliding in and out to feel the sensation around his entire length. He placed his hands onto the Predator's chest as he pumped away, gasping and trying to go as fast as he could. He had never done this act with his subject before, and there seemed to be no refusal as he thrust one last time and shot his load into the alien, who remained rather quiet.
Quickly catching his breath, the doctor pulled out and altered his position above the alien. His quick action had served as a demonstration as he sat above the Predator and rubbed the head of the newly erect green cock against the crack of his rear.
The Predator lifted his head to watch, understanding what he was to do in order to gain another unique method of pleasure. He casually observed as the human lowered himself onto his member, taking it slowly within himself. He did not expect the rush of tight warmth to be so overwhelming, and so he voiced his pleasure loudly, pushing with his hips just as before as the human fully absorbed him. Their cries and moans mixed in a sort of unearthly symphony. The human stroked his own dick as he let the Predator push and pull within him. Both quickly reached their peaks, Robert jetting his cum onto his partner's chest and the Predator screeching once more, his hands placed on his mate's hips as he moved him up and down on the surging cock, unaware that his restraints had been released.
They both heaved a final gasp and Robert collapsed onto his subject's chest, holding its sides, allowing it to come to terms that it had now been liberated. "You are free..."
"We...are...free," the Predator corrected.
Twenty minutes later, at exactly four o' clock in the afternoon, the head supervisors entered the lab, suspicious of the doctor's condition. What they discovered left them in disbelief and ended the study altogether: a destroyed lab, all data lost, and the disappearance of one of their most important employees, let alone the main subject. The experiment was considered a failure; its reason remaining undisclosed.
