Juro's eyelids fluttered open, his mind foggy and disoriented. For a blissful moment, he thought perhaps it had all been a terrible dream - the abduction, the alien breeding, the impossible violations he had endured. But as awareness returned, the aches and soreness in his body told a different story.
He blinked, trying to focus his bleary vision. A tall, slender figure loomed over him, its form resolving into something straight out of an entomologist's fever dream.
The alien before him resembled an enormous praying mantis, easily seven feet tall. Its segmented body was a shimmering, iridescent green, the exoskeleton gleaming under the harsh lights. A triangular head swiveled on a long, flexible neck, compound eyes glittering with alien intelligence.
But it was the alien's arms that drew Juro's horrified gaze. Instead of the expected two limbs, six long, jointed appendages sprouted from the mantid's thorax. Each arm ended in wickedly sharp, serrated claws that clicked together softly as the creature moved.
"Ah, you're awake. Excellent," the insectoid being said, its mandibles clicking softly as it spoke. Despite its monstrous appearance, the alien's voice was cultured and refined. "I do hope you're feeling sufficiently recovered. We have much work ahead of us."
Juro tried to speak, but his throat was raw and his mouth felt stuffed with cotton. He managed a feeble croak.
"Oh, where are my manners?" the mantis-like alien exclaimed. "I am Zix'ka, from Goggalan. I'll be overseeing the next phase of your breeding regimen."
Juro shuddered at the clinical way the alien referred to his ordeal. He tugged weakly at his restraints, but they held firm.
"Now then," Zix'ka continued, seemingly oblivious to Juro's distress, "before we proceed with the next round of insemination, we must first clean you out thoroughly. Can't have the genetic material from your previous partners interfering with my own contributions, after all."
Juro's eyes widened in panic as he realized the alien's intent. He began to thrash weakly against his restraints, muscles protesting after the earlier ordeal.
"P-please, no more," he whimpered. "I can't take it."
Zix'ka made a soft clicking sound that might have been meant to be soothing. "Now, now, there's no need for distress. Let's get you cleaned out and ready for the next phase, shall we?"
Two of the alien's long, jointed arms reached for Juro's spread legs. With surprising gentleness, Zix'ka grasped Juro's thighs and lifted them, pushing his knees back towards his chest to fully expose his abused hole.
Juro whimpered as cool air wafted over his tender, puffy rim. He could feel the seed from his previous breeding sessions still sloshing heavily inside him. His stomach churned with revulsion at the thought of being pumped full of yet more alien ejaculate.
"My, what a mess," Zix'ka tutted, mandibles clicking. "We'll need to flush you out thoroughly before proceeding."
Zix'ka manipulated the breeding bench controls with deft, precise movements of his multiple clawed appendages. The restraints shifted and repositioned, rolling Juro onto his shoulders and hiking his hips high into the air. His legs were pushed back towards his ears, folding him nearly in half and putting his gaping, sloppy asshole on lewd display.
Juro squirmed in humiliation at the obscene position, feeling horribly exposed. His muscles protested the extreme stretch, still sore and overtaxed from the relentless breeding.
A soft whirring sound drew his attention upwards. A gleaming metal pole was lowering from a panel in the ceiling, positioning itself directly above Juro's upturned ass. As it descended closer, Juro could make out more details of the ominous device.
The business end of the pole was fitted with an array of soft, flexible barbs and hooks. They curved and spiraled around the shaft in an intricate pattern, glistening wetly under the harsh lights. The appendages undulated gently as if alive, squirming eagerly in anticipation of their task.
Juro's eyes widened in horror as he realized the cruel implement's purpose. He began to thrash against his bonds, babbling pleas that fell on deaf ears.
"P-please, you can't! Don't put that thing inside me!"
Zix'ka regarded the human's struggles with clinical detachment. "You may experience some discomfort," the insectoid explained matter-of-factly, "but I assure you, this apparatus is quite safe. The textured elements are designed to efficiently scrape your rectal walls clean of foreign genetic material without causing undue damage."
The mantis-like alien tapped a few commands into a holoscreen. The pole whirred to life, the barbs and hooks writhing more energetically. A viscous, translucent slick began to ooze from ports along the shaft, coating the wriggling appendages until they glistened obscenely.
"Once activated, the device will enter your body and perform a thorough cleansing," Zix'ka continued. "The repetitive plunging motion and twisting of the textured shaft will churn up the deposited semen and allow it to be suctioned out. Like so..."
Juro could only watch in mounting dread as the pole positioned itself at his twitching, puffy entrance. For a moment, the slick, undulating tip just rested against his rim, smearing it with the strange lubrication. Then, with a smooth, inexorable pressure, it began to push inside.
Juro sucked in a deep breath as the thickly textured shaft sank into his body, the slick barbs dragging against his sensitive inner walls. The pole pushed relentlessly inward, displacing the heavy deposit of alien seed that filled his guts. Humiliated tears streamed down Juro’s face as he was invaded and violated anew.
With a soft click, the pole locked into place, the base sealing against Juro's stretched rim to create an airtight seal. For a moment, everything was still. Then, with a whir of machinery, the device came alive inside him.
The shaft began to piston in and out, fucking into him with rapid, shallow thrusts. At the same time, it rotated, the curved appendages swirling and scraping against his tender walls. Juro howled at the intense sensation. It felt like he was being scoured from the inside out, every nerve ending lit up with unwelcome stimulation.
The churning pressure seemed to find every pocket of deposited seed, stirring it up and mixing it into a frothy slurry. Lewd squelching noises filled the room as the apparatus worked him over, punctuated by Juro's agonized groans.
Just as Juro thought he couldn't take anymore, the direction of the rotation changed, the textured shaft now twisting in the opposite direction. A wail tore from Juro’s throat as the barbs scraped over his prostate, setting off sparks behind his eyelids.
"Ah, I believe we've achieved sufficient consistency," Zix'ka remarked, eyeing a readout on the holoscreen. "Initiating evacuation sequence."
A horrible sucking sensation engulfed Juro's lower half as the pole began to draw the liquid mess out of him. His abdomen clenched and seized as his guts were forcibly emptied, the apparatus rising incrementally as his insides were cleaned.
With a final slurping sound, the pole extracted itself from his body, the tapered tip popping free of his gaping hole. Juro whimpered as he felt cool air waft over his freshly scoured passage. A profound sense of emptiness overtook him, his stretched hole clenching weakly around nothing.
Zix'ka tapped a control and the pole ascended back into its ceiling recess, strings of pearly slime trailing in its wake. The mantid turned to face the doorway, mandibles clicking in a pleased manner.
"Marvelous timing. The subject is now fully prepped for the next stage."
Juro craned his neck, following Zix'ka's compound gaze. His heart sank as he saw Professor Tok and the rest of the class filing into the room.
Professor Tok glided over to the breeding bench, tentacles undulating gracefully. It glanced at the holoscreen readout.
"Excellent work, Zix'ka," the professor praised. "The subject's passage appears optimally prepped for further insemination. However, before we proceed, I believe we can take additional steps to enhance his receptivity."
Professor Tok turned to address the mantid-like alien. "While the subject is in this position, I recommend applying anal suction to increase blood flow and sensitivity in preparation for your insemination. This will enhance the chances of successful fertilization."
Zix'ka's head bobbed in agreement, compound eyes glittering. "Of course, Professor. An astute suggestion."
The insectoid moved beyond Juro’s vision, but returned shortly carrying a strange device. It appeared to be a clear cylinder, roughly the size of a soda can, with a flared opening on one end and a small hose attachment on the other.
Juro's eyes widened in horrified understanding. He renewed his struggles, but could only wriggle pathetically in his bonds. With his ass hiked up in the air, the result was that Juro looked like he was shaking his ass in anticipation.
Zix'ka clicked in amusement and affixed the open end of the cylinder over Juro's defenseless hole, the edges conforming to create an airtight seal.
There was a click then the machine whirred to life. Juro yelped as he felt a sudden tugging sensation and the puffy flesh around his anus was pulled into the cylinder. The pressure increased incrementally as the machine generated a powerful vacuum, drawing more and more of his sensitive tissue into its implacable hold. It felt like the device was trying to suck his guts out through his ass.
"There we are," Professor Tok said, satisfaction evident in his tone. "Note how the subject's anal rim engorges and darkens as blood flow increases. The heightened sensitivity will make him exquisitely receptive to Zix'ka's ministrations."
"We'll let that work its magic for a bit. In the meantime, let's see what we can do about these." Professor Tok turned its attention to Juro's chest. The human's nipples were still puffy and swollen from Rorne's earlier vibrational teasing, the tender nubs flushed a deep pink.
"Hmm, yes, we can definitely work with these," the alien mused, noting how Juro gasped and flinched with each poke and prod at his sensitive peaks. "But I think we can coax an even stronger response with the right stimulation."
Professor Tok reached for a small jar on a nearby tray. When he unscrewed the lid, a potent menthol scent wafted out, making Juro's eyes water. The alien dipped the tip of a tentacle into the pale green gel and then smeared a generous dollop onto each of Juro's nipples.
Instantly, a searing tingle spread across Juro's chest, centered on his vulnerable nubs. He gasped at the intensity, back arching as much as his restraints allowed. It felt like every nerve ending in his nipples had been set alight, the sensitive flesh pebbling and tightening almost painfully.
"This salve contains a potent vasodilator and nerve stimulant," Professor Tok explained as he rubbed the gel in slow circles, ignoring Juro's whimpers. "It will dramatically increase blood flow and sensitivity in the mammary tissue, accelerating the development of the glands."
Professor Tok worked the unguent into Juro's tender buds, pinching and tugging at the reddened peaks until they were hard and throbbing, standing out prominently from the human's flushed chest. Juro writhed as jolts of mingled pain and unwanted pleasure radiated from his abused nipples straight to his groin.
Apparently satisfied with his handiwork, Professor Tok turned and picked up two clear domes trailing tubes that led to a softly humming device.
"Now we'll take some baseline measurements and begin active stimulation." The alien attached the cups over Juro's tingling nipples, the flexible rims conforming to his areolas and sealing with a soft hiss.
Juro tensed as he felt a slight tug on his sensitized buds, then gasped as the machine engaged fully. A powerful suction engulfed his nipples, rhythmically massaging and pulling on the tender flesh. Juro tried to control his breathing, sucking in air through his nose. He squirmed at the demanding sensation, his chest growing warm and heavy as blood rushed to the area.
Professor Tok watched the device's readouts with rapt attention. "Excellent response so far. Milk ducts are engorging and alveoli are awakening." He traced a tentacle around the rim of one dome where it met Juro's skin. "Note the additional swelling and increased elasticity of the tissue. The glands are preparing for functionality."
The professor made some minute adjustments to the pump's settings, the pressure increasing incrementally. Juro whined through gritted teeth, eyes squeezing shut as the merciless suction sent equal jolts of pain and forbidden pleasure shooting straight to his core. He could feel an answering throb from between his legs as his ignored cock began to fill and stiffen once more.
Professor Tok smirked at the human's reaction, reaching out to give Juro's shaft a few mocking strokes. Juro shuddered, hips bucking into the touch helplessly, seeking any scrap of friction.
"Note the subject's persistent genital arousal in response to the mammary stimulation," the professor remarked to the class. "This is a remnant of his masculine conditioning. Continued denial of penile gratification combined with positive reinforcement of oral, anal, and nipple stimulation will redirect the subject's perception of pleasure."
Professor Tok turned to address the eagerly watching class. "While the suction devices work to prepare the subject's body, we can further his training by focusing on the penile structures. Each of you will take a turn sounding his urethra, but take care not to allow him to ejaculate. We want to reinforce the association between sexual pleasure and internal stimulation only."
The students eagerly crowded around the breeding bench, their alien eyes gleaming with dark anticipation as they took in Juro's vulnerably splayed form. Professor Tok watched in satisfaction as the first volunteer stepped forward, a slim, silvery rod clutched in its appendage.
"P-please, don't--" Juro's plea cut off with a strangled yelp.
"Remember, insert the sound slowly and apply steady pressure," Professor Tok coached. "The lining of the urethra is delicate. We want to stimulate, not damage."
Professor Tok tentacles squirmed in delight as Juro's cries rose in pitch, growing more desperate and broken with each millimeter the sound penetrated.
"Very good," Professor Tok praised as the student worked the rod deeper still. "Note how the urethral lining stretches to accommodate the intruding object. With time and training, the channel will adapt to accept larger and more textured instruments. Remove the probe and pass it to the next student."
