"Fuck!Fuck!Why is this freak bitch so fucking hot? I can't stop coming!"

"His pussy! God, what's wrong with his pussy? Ineverwant to pull out! I can't! FUCK!"

Finding more men to help breed Tae's insatiable cunt had been easy-- one, Martin, had shown up to take over watch duty in front of Tae's door and the other, Tom, had arrived as backup when they realized Jackson was nowhere to be found. Fortunately, while the two men were quite skilled in combat, they weren't the brightest stars in the galaxy so it wasn't hard for Jackson to talk them into entering Tae's room and the wit-dulling, arousal-inducing pheromones the scientist's heavily pregnant body was emitting took care of the rest.

Both guards were undressed and on top of Tae in less than thirty seconds-- moaning and swearing their way through their first mind-shattering orgasms the moment they thrust their stiff and leaking cocks into his rapacious body.

"Shit, my wife's gonna fucking kill me," Martin groaned, eyes rolling back and mouth hanging open as he crouched over Tae and fucked his pussy like a stud would a bitch in heat.

"Your wife's light years away, you dumb bastard-- she won't know shit if you don't tell her," Tom panted while he focused on fucking the same hole as his friend, lined up directly behind Tae so they could both take him at once.

Beneath them, flushed and moaning, egg-bloated belly pressed into the carpet under him while he rested on his hands and knees in the center of his quarters, Tae stopped sucking Eric's dick long enough to say, "Don't worry, I won't tell, baby. Just-- ah! Just don't stop!"

Martin, a robust, muscular young man with dark skin and short-cropped hair groaned and thrust harder into Tae's unnatural, unflagging cunt, utterly addicted to its tight, slobbering, mouth-like embrace. "Mmm, yeah, that's a good boy. You keep your mouth shut and maybe I'll give you a baby too, huh? Just like my wife! It can be our little...secret!"

Tae moaned again, pussy going tight around the cocks inside of it at the promise of future impregnation. He couldn't tell the security guard how much he liked the idea, though-- Eric had already pushed his cock back into his mouth and was now fucking the scientist's throat, hips setting a breakneck pace that left his pretty cocksleeve sucking, gargling, and drooling around his shaft.

"Seriously, where has this slut been all my life?" Tom panted, sweating with the effort of plunging his cock in alongside his friend's, relishing the slippery, greedy heat of Tae's voracious hole. "He's so wet it's like he's pissing out his cunt! Bet the bitch could take five more dicks if there was room for the bastards attached to them back here!"

Above him, Martin decided to test the waters and pushed several slick fingers into Tae's twitching asshole, making the taut ring of muscle flinch before it loosened abruptly and seemed to suck him in deeper.

"Fuck, dude, his asshole's amazing too, look at him take me!" the guard exclaimed, laughing incredulously as he fucked his new favorite toy with first three fingers, then four. Tae squirmed beneath him, moans around Eric's cock growing louder but he didn't try and pull away. "Yeah, you like that, bitch? You want all your slut holes pounded at once?"

"Pleeeaaaashh!"Tae practically wailed, pleading garbled by the cock plunging in and out of his mouth.

"If you insist!"

Martin forced his entire hand into Tae's ass with one hard thrust and the scientist came, howling with the power of his orgasm as the security guard fisted him. More of the clear, viscous lubricant his pussy was producing gushed out, splashing to the floor and onto their writhing, lust-contorted bodies as they humped, groaned, and copulated like animals.

The men fucking Tae pounded every hole on his body like mad dogs, feeding his voracious womb load after load of the seed his own pheromones had sent their bodies into overdrive producing. No doubt Rollins or Wolfsfeld would have found it all very interesting from a scientific standpoint, but all Tae could think about was taking as much of it as possible--

Until he wasn't.

Something changed after awhile, though focused as he was with leisurely suckling Martin's flaccid cock in hopes of drawing out a little more come while laid out on his back, Eric pounding his sloppy, gaping pussy, it took him some time to notice.

His compulsive craving for semen was gone, though that didn't inspire any desire to pull away from any of his dogged paramours. A thrill of excitement raced through Tae as he sensed the impending change when his body reached the next stage and his womb pulsed and quickened strangely inside of him.

"E-Eric," he gasped hazily, lazy fellatio of Martin's used-up cock forgotten as he rubbed the enormous swell of his distended, stretch-mark laced belly. "Hurry, it's...ah! It's time!"

"Time? It's time..." Eric panted, eyes unfocused, face flush and streaming with sweat from his hours long breeding session. At this point it was hard for him to even string a sentence together, let alone understand one, lust-addled as his brain was. Any thoughts more complicated than "fuck", "come", or "rest until I can come again" just sort of...slipped away-- normal concerns of his day-to-day life finding no purchase in a brain whose higher functioning had shut down hours ago and handed over all control to his purely instinct-driven lizard-brain.

Martin and Tom were in an even worse state, both currently sprawled on the floor, fucked out and too spent to continue, but watching Eric and Tae copulate relentlessly all the same. None of them realized it, of course, but Eric's exposure to Tae's pheromone laced body fluids days before in the elevator had given his physiology a head start adapting to what would be required of it as a sperm donor for the alien brood incubating in Tae's belly.

A brood that was beginning to shift down in preparation for what was coming next.

Tae felt his offspring's weight drop lower in his abdomen and groaned, back arching as the first echo of a contraction took him. "Eriiiic!" he moaned again, louder this time, but still the man on top of him continued to thrust, thick cock sliding in and out between the plump, swollen lips of the scientist's vulva.

"I-- I'm almost..." the guard grunted with effort and grabbed at Tae's huge belly for leverage as he put his back into thrusting. The surface of the scientist's stomach felt bloated now, and Eric was unable to feel each individual egg where it pressed at him from within anymore, though the fact barely registered as he focused on finishing. When he finally did, it was with a low, whimpering cry as he spilled the last of his seed against the altar of Tae's abused and pulsing cervix before he pulled out and collapsed to one side, chest heaving as he fought for breath.

Tae barely even noticed him go, too busy struggling under the weight of his belly, overcome by the sensation of his womb squirming and convulsing abnormally inside the over-crowded vessel of his body.

A real contraction took the young scientist then and he screamed as the power of it forced him to nearly double over around the hot, leaden weight in his abdomen.

Something wasn't right. The xyloid had planted its eggs in him-- surely he was supposed to lay eggs? Instead, one,hugemass was pushing towards the entrance of his pussy in search of escape, throbbing in time with his frantic pulse while Tae's whole body fought to expel it.

"I-- oh god! I can't! It's too big!" he shouted, cries turning into a wordless scream of agony that trailed into pleasure as Tae's birth throes brought on another orgasm accompanied by a gush of fluids from his gaping, twitching cunt. The men around him were useless, too far gone to do more than stare as he labored to birth the alien mass trapped inside his body.

Tae could feel his pubic bone flex and spread unnaturally before the weight bearing down on it and his pelvis floor bulged outward at its imminent arrival while his pussy started to spread of its own accord.

Several floors away, Wolfsfeld watched Tae labor through a camera feed from the relative safety of his own lab while Rollins observed from nearby. After Tae had somehow managed to coax not just Jackson, but the other security guards into his room the pair had decided it was too dangerous to venture down there themselves and opted to study what came next instead.

What had followed was a literal orgy as the security guards fucked Tae's gravid body from any and all angles they could manage, all preferring to unload in his pussy but willing to take whatever orifice they could shove their dicks in until space opened up.

"These readings are strange," Wolfsfeld said and frowned while he observed the results of his latest scan of the occupants in Tae's room. Higher brain functions in the security guards had been dropping steadily but Tae's were even stranger. His body was mutating at a rate that was difficult to track with such unsophisticated equipment as what he had been able to smuggle in there before his assistant had woken up from his anesthesia days before. The area of his womb was proving particularly difficult to scan, like the tissues there had thickened unnaturally to shield its contents and he could no longer track just what kind of life was developing therein.

Rollins only grunted and Wolfsfeld glanced at him sidelong. Truth be told, he'd stopped fully trusting the doctor-- whatever influence Tae was having on people had particularly affected the doctor, no doubt thanks to the multiple exposures he'd had to the younger man's fluids. He could still string a sentence together, but only when Wolfsfeld pressed him, and that was before he'd come into the room to find him masturbating shamelessly to the video feed of the men copulating in Tae's quarters just that morning.

Not that he was much better.

Even now Wolfsfeld himself was sporting a raging hard-on and it took every ounce of his considerable self control to keep from touching himself while he watched the writhing, lascivious morass of tangled bodies of on the video feed before him.

God but the little breeder was fuckinggorgeousas he labored under the weight of the alien offspring forced into his beautiful, nubile body. Eager for a better view and telling himself it was for science, Wolfsfeld adjusted the camera feed to give them a prime view of Tae's bulging, straining pussy and both men leaned in closer to the screen to watch.

Tae hadn't bothered to turn off his computer or lock his system in days so Wolfsfeld had long since tapped in to the microphone so they could hear his labored screams of effort as he struggled to give birth.

"There! There it goes," Rollins breathed softly as something glistening and pink finally breached the thick outer lips of Tae's labia. "Look at him," the doctor mumbled while he began to touch himself unconsciously, face flushed and eyes riveted on the screen. "God justlookat him."

Wolfsfeldwaslooking at him and his cock was straining harder than ever against the zipper of his fly as a result. He, too, caught his breath as Tae bore down with a particularly loud shriek and pushed more of the pink, fleshy mass out from between his trembling thighs.

Definitely not an egg,part of Wolfsfeld thought while the rest of him pulled out his dick and began to jerk off to the aberrant birth occurring before his eyes.

Rollins stood up abruptly, his chair toppling over backwards when he did. "I have to go to him. He-- he's struggling," he said and turned to leave.

Before he got more than a step, though, Wolfsfeld surged to his feet and grabbed the man by the arm. "Like hell! We can't afford to lose our only doctor, fool," he ground out and pushed the man back towards the desk.

The doctor tried to leave again, though, so Wolfsfeld grabbed him from behind and pushed him up against the desk a second time, this time hard enough to make Rollins grab the edge.

Aroused as he was and poisoned by Tae's pheromones, the scientist caved to his own base instincts after a moment's scuffle with the taller, but much slimmer man.

"I saidstay, bitch"Wolfsfeld snarled and pushed down Rollins' pants to press the head of his cock against the other man's hole. "This what you want? Want to be like our boy there?" the scientist growled softly in the other man's ear as he gripped him tight from behind.

"I-- I don't-" Rollins began, but too late. Wolfsfeld slicked up his cock then pushed into the tight pucker of his hole, forcing it to spread and take his full length in one rough, impatient thrust.

Rollins writhed and cried out, trembling under Wolfsfeld as the older man took him by force, but by the time the scientist was lodged in him to the hilt, he'd submitted.

"That's right," Wolfsfeld murmured, groaning a little at the tightness of the other, obviously inexperienced man. "You make just as good a bitch as Tae, don't you? Wish you were giving birth like him?"

Rollins didn't respond, but his cock was out and weeping precum as the scientist began to thrust slow and steady in and out of his straining hole while they both watched, transfixed, as Tae gave birth.

The thing that finally spilled out from between Tae's thighs wasn't an egg or even a child-- but a pink, fleshy sack that looked as if the man had labored so hard his womb had prolapsed.

It was far too big for that, though, and it looked too intact-- like it was meant to do that.

~~~

Trembling and weak in the wake of his brutal labor, it took Tae a minute before he was able to push himself upright to see what it was he had birthed. The sight that greeted him was strange, and yet, for some reason, felt completely natural.

The pink, muscular organ resting on the floor between Tae's legs was bigger than a watermelon and shaped roughly like a wasp's abdomen. Rather than a sting at it's tapered point, however, there was a small opening-- the mutated remainder of his cervix, the scientist realized abruptly as he studied the strange organ.

It was hot and slippery against his skin when Tae reached out and touched it, his palms gliding smoothly over its pink, glossy surface as he gently palpated its mass. He couldn't make out the eggs he presumed were inside but there was no denying that it was definitely a part of his body-- the organ, his...hisovipositor(?),was sensitive to the touch when he stroked it.

It felt good.

Curious, he carefully got to his feet and was startled by the apparent strength of his hugely swollen organ as it not only bore up under its own weight, but jutted out before him not unlike a cock.

Intrigued, Tae turned to Martin where he sat on the edge of the bed, staring at him, gape-mouthed, then said, "Suck it."

"What is it?" Martin asked, staring. The unnerving sight wasn't enough to stop him dropping instinctively to his knees in front of Tae, though.

"My womb. Don't you want to try?"

"I... yeah. Yeah I do," Martin confessed honestly, transfixed by the enormous, gently pulsating member hanging in the air between their bodies. Without further prompting, he took the tip in his mouth and began to suck, eyes rolling back in his head at the indescribable flavor of it while he teased the tight pucker of what had once been Tae's cervix with his tongue.

"That's it-- ah! Just like that," Tae groaned, hips rolling gently while he stroked his ovipositor with one hand, keeping it steady so Martin could suckle at the tip.

The longer the man kept at it, the longer the tip seemed to grow until Tae could feel it hit the back of the other man's throat.

"That's it, bitch, deep throat me. Take me all the way...!"

A new sensation overcame Tae and he moaned loudly as his ovipositor convulsed powerfully and ejaculated a long, thick rope ofsomethingstraight down Martin's throat. The man choked and tried to pull away, but Tae grabbed him by the head and held him in place as he groaned his way through a new kind of orgasm until the other man had swallowed down all he had to give him.

When Tae pulled out, Martin retched and shuddered even as he orgasmed feebly, a weak stream of seed spilling out across the floor between his knees. "What-- what was that?" he rasped weekly, one hand at his throat, a dazed look overcoming his face while Tae ignored him and moved towards Tom.

"Wait," the redheaded man began, but all Tae had to do was glance at Eric and the other man quickly jumped up to be of use.

Catching Tom unaware, Eric wrestled him face down onto the bed so Tae could straddle his thighs and mount him from behind. The man's strange ovipositor was soft to the touch but the tip seemed almost prehensile as Tae lined himself up and nudged his organ between the cleft of Tom's ass and easily slid up and into him by at least six inches. That left the bulk of the ovipositor's mass between the press of their bodies, a hot, slippery, foreboding presence until Tom began to loosen and relax, panting like a mindless bitch as Tae fucked him.

"So this is what it's like?" Tae grunted as he thrust blissfully into the other man, enjoying the sensation of pressing his massive, swollen womb between their bodies, now acutely aware of the pulsing, squirming mass of life developing within. "Fucking a man's hole? Feels...ohgod,you feelso good,"he groaned and came a second time. He lingered inside of Tom, though, riding the exhilarating high of forcing himself onto a moaning, whimpering slut and emptying himself into him longer this time. Whatever it was inside of his ovipositor Tae was coming to realize he could control how many he released and it gratified him to plant two inside of Tom's eager body and watch as the other man writhed and came all over himself in the aftermath, half-mad with pleasure at the sensation of Tae's spawn slithering ecstatically in his guts.

~~~

Despite how many times he'd come already, Eric was hard again watching Tae fuck Tom and Martin, the scientist's beautiful face contorting into a mask of euphoria as he filled them.

Fuck, I need him so bad,Eric thought, already jerking himself off in a vain attempt to achieve the same level of pleasure. It wasn't enough, though-- it was never enough, and the man was dropping to his knees at Tae's feet before he even realized what he was doing-- the most primitive part of his brain taking the reins once more and making him debase himself without a second thought if there was the slightest chance Tae might fuck him too.

"Please," Eric panted and opened his mouth in supplication, eager to take the tip of the scientist's ovipositor the same way Martin had.

Tae looked at him, dark eyes glittering and impenetrable, then smiled. "No," he said simply, then reached down and helped Eric to his feet. "Not like that. You...you I want to feel in here," the man breathed and stroked his swollen, everted womb where it hung provocatively in the air between them.

Dizzy from the rush of swinging radically from disappointment to elation, Eric nodded frantically, his entire body aching to please Tae, no matter what he asked of him. His pleasure was Eric's pleasure, and the fact Tae had chosenhimto penetrate this most sacred part of his sublime, evolving body was so intensely gratifying it was nearly enough to make him come again before he'd even laid hands on the man.

The security officer managed to restrain himself, though, and reached between their bodies to stroke Tae's glorious, gravid womb and line himself up with its delicately pointed tip. Eager to please but desperate not to disappoint, Eric carefully pressed the head of his cock into the warm, fleshy mass, its soft surface giving way before his rigid member to fold back in on itself. He could feel the tight little pucker of Tae's cervix though, so the man took firm hold of the heavy organ and thrust firmly against it, seeking entrance.
