Breeding the Earthling

BREEDING THE EARTHLING

Chapter Four

A sleek, sharply angular figure glided forward from the crowd, its movements swift and predatory. As it emerged into the light, Juro beheld a creature that seemed to embody the perfect fusion of humanoid and shark.

"Ahh, Gex of the Kharka," Professor Tok said. "Known for their voracious appetites and... unconventional anatomy. Your species' compatibility with this host should yield fascinating results."

Gex stood upright on two powerfully muscled legs, his body encased in smooth blue-grey skin. A dorsal fin protruded from his back, tapering into a sinuous tail that lashed behind him. Gill slits flared along the sides of his thick neck with each breath.

But it was the alien's head that made Juro's blood freeze. A streamlined, wedge-shaped skull sat atop broad shoulders, like the hammerhead sharks Juro had seen on nature documentaries. A lipless mouth split Gex's face nearly from ear to ear, filled with multiple rows of jagged, razor-edged teeth.

And set wide on either side of that nightmare visage were two sets of eyes, cold and black as a shark's, reflecting the light with an eerie sheen. All four of those pitiless orbs fixed on Juro's trembling, come-splattered form with undisguised hunger.

The shark alien sauntered up to the breeding bench, his powerful tail swaying behind him. A deep, rumbling croon emanated from his chest.

"What a cutie," Gex exclaimed. Despite his appearance, the alien's voice was high and excited. He reached out with a webbed hand to stroke along Juro's cheek. "How much cuter will you become? Hm? Will you make adorable sounds for me?" Gex leaned back, his genital slit parted, and Juro's eyes widened as they realized what the professor meant by "unconventional."

Jutting out from the shark man's waist were two long, tapered penile organs, side by side. Each penis was a deep ocean blue fading to pale grey at the tip, and ribbed fleshy pearls along the sides. The heads were smooth and rounded, almost bulbous. The twin members pulsed and twitched with obvious arousal, a viscous clear fluid already beading at the crowns and dripping down the textured shafts.

"Ahh yes, as you can see, the Kharka are unique in possessing dual intromittent organs," Professor Tok remarked, gesturing at Gex's straining cocks with a tentacle. "This adaptation allows the males of their species to deposit a greater volume of semen and increases their chances of successful fertilization."

Juro shuddered at the words, bile rising in the back of his throat at the reminder of what these creatures intended to do with him.

Gex prodded at Juro's raw, puffy hole and Juro gasped as one finger dipped inside. "Such lovely coloring," he hummed. "So pink. So cute!" Gex pumped his digit in several times before adding a second, sliding in easily through the mess left behind by Bocci. "The Fido left a suitable lubricant. Best to make use of it before it goes to waste."

The shark-man withdrew his fingers with a wet squelch, a trail of goopy fluid connecting them to Juro's gaping rim. Gex smeared the slick over his left cock, the more prominent of the two, coating the rigid flesh. "The left one is first today. How lucky!"

Juro could only watch in horrified anticipation as Gex notched the slick, flared tip of his cock against his opening. Despite Bocci's thorough fucking, Juro felt daunted by the sheer size of the shark's endowment. The head alone seemed too big to fit inside him, much less the thick, ribbed shaft.

Gex grinned, showing off multiple rows of razor-sharp teeth. "Deep breath, little human."

"Please, no, wait--"

The shark-man rocked forward, the thick head of his cock breaching Juro's slick, tender entrance. Even stretched open from the earlier breeding, Juro struggled. He cried out as the spongy head popped past his sphincter, the crown settling just inside his rim.

"You're quivering around me, little human. So cute!"

Gex pushed forward relentlessly, feeding his long, thick cock into Juro's clinging heat inch by agonizing inch. Juro moaned as he felt each fleshy ridge pop past his rim one by one, the textured surface dragging against his sensitive walls. That cool, ocean-slick shaft delved deeper and deeper, stretching him wide around its girth.

Juro could only whimper in response, eyes squeezing shut as he tried to relax his resistant muscles. Finally, after what felt like an eternity, Gex's angular hips pressed flush against Juro's upturned ass.

Juro panted harshly through his nose, trying to adjust to the intrusion. Gex's left penis was longer than Bocci's, reaching even deeper to poke at Juro's abused cervix, but not quite as thick.

"I wonder which of my cocks you'll prefer, cute human," the shark-man purred. "Shall we find out?"

Without warning, Gex pulled out completely and then thrust back in, spearing Juro open on his throbbing shaft in one smooth motion.

Juro's back arched off the chair. The sleek, ribbed texture of Gex's cock scraped deliciously against his inner walls, the shark's member pulsing and flexing as it worked its way deeper into Juro's body.

"Well? What do you think of the left one? Does it make you feel good? I want to hear more of your sweet sounds, cutie! Come on, cry for me!"

Gex sawed in and out of Juro's hole, the obscene wet slap of flesh against flesh echoing through the room along with Juro's pitiful cries. Gex's powerful hips drove his rigid flesh into the helpless human with ruthless precision. Each pump of the shark-man's cock pushed Juro further up the table, his body rocking bonelessly with the force.

Juro panted harshly through his nose. Tears streamed down his face as that relentless cock pounded into him, turning his insides to molten jelly. Horrible, shameful pleasure coiled in his gut as each fleshy pearl rubbed maddeningly over his inner nerves, sending unwanted jolts of pleasure sparking up his spine.

"Marvelous," Professor Tok narrated, "Note how the Kharka's member is lined with fleshy barbs and ridges. These textures serve to stimulate the partner's inner walls and provide extra friction to aid in triggering orgasm and drawing the male's seed deeper."

His lower set of eyes stayed fixed on Juro's trembling form while the upper set flicked over to the Professor. "Let's see how he likes the other one, shall we?"

Without breaking rhythm, the shark-man shifted his hips, letting his left cock slip free of Juro and replacing it with the right one.

The right member was shorter but deliciously thick, the flared head grinding against Juro's prostate with every thrust. Sparks exploded behind Juro's eyes, heat sizzling up his spine as that secret spot inside him was relentlessly stimulated.

Gex fucked into him hard and fast, each snap of his hips punching breathy little "ah-ah-ahs" from Juro's slack mouth.

Gex's hips pistoned relentlessly, his right cock hammering into Juro's gland with ruthless precision. Juro wailed, back arching as much as his restraints allowed, toes curling from the intense sensations radiating from his core. His own neglected member bobbed uselessly against his stomach, drooling pathetically as Gex's thick shaft dragged over his sweet spot again and again.

"So? Which of my cocks do you prefer, little human?" Gex purred, not slowing his brutal pace. "The long one to stir you up inside you? Or the thick one to batter that little pleasure button until you're sobbing for release?"

Juro could only whimper brokenly in response, brain short-circuiting from the overwhelming stimulation. Drool leaked from the corners of his slack mouth, eyes rolling back as Gex used his body.

"Can't decide?" Gex chuckled darkly. His black, soulless eyes gleamed with sadistic glee. "Perhaps you should try both at once, yes?"

Juro's eyes flew open wide with panic, a choked protest garbling in his throat. Surely the shark-man couldn't mean to...he was already so full. There was no way he could take both of those massive members in his already overstuffed hole. It would tear him apart!

But Gex just grinned, all sharp teeth and dark promise. He pulled out and pushed his dicks together so the bulbous tips of both his dual cocks were nestled against Juro's asshole.

"N--no, no, no, NOOOO!"

Gex flexed his powerful hips and thrust forward, plunging both thick lengths into Juro's straining body in one brutal stroke.

Juro screamed, back bowing as he was split open on the shark-man's double cocks. The long one sank deep into his colon, while the shorter, thicker one pressed mercilessly on his swollen prostate. His walls strained around the massive intrusion, stuffed to the point of breaking.

Gex groaned in satisfaction, his rows of gills flaring as he savored Juro's tightness. "Fuck, you so good! Such a good boy. Such a cute boy. Let me make you feel good too. Hold on tight, cutie. I'm going to fill you up!"

Each time Gex pulled out, it felt like Juro's insides were being dragged out as well. He could barely breathe as the shark man pumped back and forth into him. Lewd wet squelches filled the room as Juro's inner walls clung desperately to the thick, ribbed shafts spreading him wide.

Professor Tok watched the coupling with rapt fascination, taking note of Juro's full-body convulsions and the steadily growing pool of precome drooling from his caged cock.

"Remarkable," the professor mused. "Subject seems to be deriving intense physical pleasure from the Kharka's unconventional technique, despite the discomfort. The dual stimulation of sigmoid colon and prostate is clearly effective in reinforcing a positive mental association with penetration and seeding."

Gex's upper eyes flicked to the professor, gleaming with dark satisfaction even as his lower set remained fixed on the writhing human speared on his cocks. "Mmm yes, I can feel him starting to surrender. So cute!"

Juro's eyes rolled back in his head as Gex used his body, turning him inside out with pleasure so intense it bordered on agony. He felt like he was coming apart at the seams, reshaped into an alien's cock sleeve.

"Get ready, cutie," Gex growled, rows of razor teeth bared in a feral grin. "I'm going to pump you so full of my seed you'll be dripping for a week."

Gex pistoned his hips faster, plunging his thick, textured cocks into Juro's straining body with animalistic ferocity. Juro was suspended in a haze of piercing pleasure-pain as the shark-man ruthlessly claimed his hole.

With a roar that sounded more animal than man, Gex slammed home one final time, grinding his cocks as deep as they would go. Juro felt them flex and swell inside him, pulsing against his battered inner walls.

The sheer volume was staggering, easily eclipsing Bocci's impressive output. Gex's dual cocks pumped a double load into Juro's stretched, sloppy hole.

Once spent, Gex's softening cocks slipped from Juro's red, inflamed hole with a wet squelch

"There," Gex stepped back, admiring his handiwork. His dual cocks, still dripping pearly strands, jutted proudly from his genital slit, slick with Juro's juices. "A double cream pie for the human cutie."

"Now then," the shark-man walked around the chair to where Juro's head lolled, "why don't you show me how grateful you are for my gift, hmm? Put that pretty mouth of yours to good use and clean me up."

Gex fisted a clawed hand in Juro's sweat-damp hair, dragging the human's head down to his groin. Juro blanched, trying to turn his face away, but the shark-man's grip was unyielding. The musky, briny scent of Gex's release filled his nostrils, making his stomach churn.

"None of that, now," Gex chided. "You'll get used to the taste." Gex angled the human's tear-streaked face towards his spent, fluid-slick organs

Tentatively, Juro extended his tongue, giving a small kitten lick to the tip of Gex's left member. The taste was overwhelming - bitter and briny, with a cloying undertone that made Juro's stomach churn. Gex chuckled darkly, pressing the flared head more insistently against Juro's lips, smearing them with his seed.

"That's it, lap it all up like a good little human. Make sure you get between all the ridges."

Juro shuddered but dutifully opened his mouth, allowing the spongy glans to push past his lips. He swirled his tongue around the tip, laving the sensitive slit, before trailing down to trace the ribbed texture of the shaft. Gex groaned in approval, tilting his hips to feed more of the long organ into Juro's reluctant mouth.

Once he had meticulously cleaned every inch of the left cock, Gex presented his right member, still glistening with Juro's own fluids and shark slick. Juro repeated the process, suckling the thick head and tonguing the pulsing veins until Gex was purring with satisfaction.

"Well done, little human," Gex praised, patting Juro's stuffed cheek condescendingly. "Such a good, sweet boy deserves a reward, yes?"

Gex withdrew his slick members from Juro's mouth with a lewd pop. He turned to address Professor Tok. "Professor, might I suggest allowing the human to ejaculate once as a reward for his good behavior and eager service? Perhaps it would encourage further obedience."

The alien professor glided closer, peering down at Juro's caged, dripping cock with clinical interest. "Hmm, you raise a valid point, Gex. Positive reinforcement could prove a useful training tool at this early stage." He waved a tentacle permissively. "Very well, you may remove the device and permit the subject to ejaculate. But he is not to touch himself - the stimulation should come only from your cocks. We must continue to train him to derive sexual satisfaction solely through penetration and being seeded."

Gex grinned, teeth glinting sharply, and reached between Juro's splayed legs. He deftly unlatched the metal cage encasing Juro's straining erection.

Juro gasped as his member sprang free, flushed an angry purple and visibly throbbing. The cool air on his heated flesh made him shudder, hips lifting up instinctively. His hands strained against their bonds, trying to reach and relieve his aching cock.

"Now, now, no moving," Gex chided, pressing Juro's hips back down onto the chair. His webbed thumb swiped across the precome beading at the tip, eliciting a choked whine from the human. "Hmm, you're positively dripping, so desperate for it. But you'll only get to come if you put your cute holes to work. Think you can do that?"

Juro shuddered at the shark-man's words, fresh tears pricking at the corners of his eyes. The thought of taking another alien inside of him made Juro's stomach clench with dread. But the urgent throbbing of his painfully hard member was impossible to ignore, the need for relief overriding all else.

He gave a jerky nod, not trusting his voice.

Gex turned to the rest of the class. "The cutie wants more. Who's next?"
