Damien ran recklessly, desperate to get to the beach before sundown, taking his usual shortcut through the woods. He’d been itching to catch some waves all day but his college make-up classes kept him indoors for the better part of the afternoon. 

This area was relatively free of tourists and there was rarely any litter or waste. Therefore, he always ran the path barefoot, not wanting to get sand in his good shoes. There wasn’t even any point in watching where he was going with how well he knew the trail!

Damien was not prepared for the shock of something hard breaking under his foot as an immense pain shot through his body. Yelling in frustration, he looked down to see some sort of canister or device lying in the middle of the path, the bottom broken where he’d stepped on it. The entire thing was about 2 feet long, with a metal cover surrounded by some strange writing in a language that Damien didn’t recognize. It seemed to be leaking a bizarre pink fluid.

This part of Hawaii didn’t get many tourists, but it was conceivable that someone could have lost a canister of…whatever that was. He considered picking it up but thought better of it, not knowing if its contents were dangerous. 

It took him seeing several drops of blood to realize he’d cut his foot on the canister. Without anything to clean it up, he’d have to head back home and miss his waves! Yet a strange burning heat from the wound made him do a double-take. The pink fluid from the canister seemed to be leaking into the open cut on his foot!

Panic set in. What was that fluid, and what would it do now that it was inside him? Ye, to his surprise and shock, he could see the cut on his foot start to heal as the pink fluid seeped into his skin. There was nothing he knew of that could heal a deep cut like that so quickly, making him fearful for what he had been exposed to. What was going to happen next?

Yet, in the end, after some internal debate, Damien decided to catch his waves after all. Saltwater would get rid of any harsh chemicals on his skin, he reasoned. And his foot felt fine. A little warm, but that was to be expected. He couldn’t really do much about it now anyway, with it being so late in the day. He would call the authorities to alert them of the potential biohazard in the morning, and maybe have himself checked out by a doctor when the clinic was open. 

Damien headed out to the water, enjoying the familiar sight of the righteous waves pounding the beach. He was going to get some good waves this evening! Surfboard in hand, Damien ran out into the waves until he was about knee-deep. He got on his board and started paddling out towards the forming crests. 

As he did, he felt the warmth in his foot began to intensify. Soon, his entire foot felt numb. His skin began to itch too, like the fierce prickling of hair covering his bare legs. It was enough to motivate Damien to turn around on his board and heading towards shore. 

Suddenly, his entire foot started to cramp up, his toes curling in on themselves as something coarse and rough touched the sandy beach. He gasped a little as his toenails ached, as though he could feel them expanding into the surf. And his heels were stretching longer, making him have to lean over on tiptoes. Yet, all he could see through the water was a strange blue shape, much different than he was used to. What the hell was going on? 

Bracing himself for the worst, Damien pulled his leg out of the water to see what had become of his foot. The entire surface was covered in what looked like spreading blur hairs! Worse, his foot could no longer be called human at this point. With rounded feet, a digitigrade stance, and short-clawed toes, they looked like the paws of an animal!

Worse, the discoloration was spreading up his leg, covering his knee, and moving up towards his hips. He gasped as his other foot began to cramp and a similar change overtook the still-pale skin. Damien wracked his brains over the cause of such a bizarre transformation. Could the canister have something to do with it?

Moving on his mutated legs felt off but Damien did his best to balance himself as his board swept back into the sea. The relentless fur continued up to his chest as his stomach started to grow lean as though the muscle underneath was mutating as well. Curiosity getting the better of him, he ran his hand over the short, coarse fur, finding it not unpleasant to the touch. Spreading it apart, he could clearly see the skin underneath had that same blue shade as the fur. 

The aches in his changing body intensified as his already-defined muscles firmed and flattened. His pecs, his chest, and even his upper arms were not spared as the blue skin continued covering him. The shading was lighter through his chest and stomach but darkened once more as it reached his arms. Damien had been a built swimmer with a little bit of a gut but the body he was being granted was lean and muscled. 

Tufts of blue hair now spread down over his shoulders and down his now-toned arms. An ache in his hands brought attention to his palms as they swelled up with thick blue pads. His fingers, too, started to fatten and shrink as the nails thickened and spread. Within a few minutes, he was left with strange blue paw-like hands, the dexterity much more restricted than what he was used to. 

A stab of pain suddenly emanating from his sides distracted him from the changes to his hands. Reaching up his paws revealed something bulging under his touch, as though his insides were squirming under the flesh. All of a sudden, something tore painfully through the sides, two protrusions of muscle that continued to stretch as he watched. What the fuck was happening? 

A terribly frightening squelching rang through his ears as his new appendages formed bones, veins, blood, muscles, and joints as they grew under his arms. An uncomfortable numbing sensation erupted from the tips as a set of fingers grew above his newly developed palms until he had another set of fucking arms growing out of his chest! What was he, some sort of bug? 

The arms soon moved as well as his main pair, if that was the proper term. He could scarcely fathom the reality that he possessed two complete pairs now. The connections seemed to be in place for him to operate them properly, though a strange sensation at the base differentiated them from his other limbs. An experimental tug caused them to retract completely into his truck. Lowering his original paws to feel the area reported a slight protrusion where they lay hidden. Further experimentation unfurled the arms just as easily, and Damien found they seemed to be able to move in and out without any trouble.

Lost in his self-reflection, Damien gasped suddenly as something started poking out of his back. Reaching behind with his main arms, his paws reported a series of several strange protrusions bursting out of his skin. He tensed as new muscles formed to work the structures, and like his arms, he could move them in and out. They seemed like some sort of retractable spines!

All the while the blue fur and skin were spreading up his neck and face. The bizarre tingling made him fearful of what changes would afflict his visage. Remembering his phone was in his bag further up the beach, he raced for it as his mouth began to ache. In his fear, Damien only cared to see what was happening, needing to see it even though the changes were robbing of his visage.

He was able to activate the camera feature in time to see his entire lower jaw pressing out into what could only be called a short muzzle. His nose started to darken towards a deep blue as it flattened in tandem with his widening jaw. Sharp pains in his mouth signaled the growth of pointed teeth, more numerous than his own had been. His puffy cheeks expanded outward, giving him a bestial grin that frightened him deep down. 

Something started poking between the hairs on his head even as they reflexively sank into the spreading blue fur around his scalp. New muscles seemed to operate the hidden appendages, reminiscent of the sensations from his extra arms. He extended them, seeing a pair of insect-like antennae waving in the evening air. The overload of sensory input they suddenly provided threatened to overwhelm his mind. Light, heat, vibrations, scents, all were picked up by the waving antenna, making him want to scream. Damien had no idea how to properly process them! 

Worse were the amplified noises from his changing ears. Their entire surface had begun to stretch out, wider even than his head. Rimmed blue edges accented thin pink flaps that seemed to tear in places, forming jagged depressions, yet Damien felt no pain from their development. The noises they detected were deafeningly loud, but his changing mind started shutting them down to more manageable levels in a few moments, much to Damien’s relief.

Finally coming to his senses, Damien tried to yell for help but all that came out was a distorted cry that frightened him. What had happened to his voice?! He tried to talk slower, enunciate his words. But still, the sounds seemed off, like he had inhaled helium. The words came out high and tinny but if he focused intently he could still understand them somewhat. He was at least thankful his vocal cords still worked!

The tinglings of alterations finally diminishing somewhat, Damien took stock of his body. The image reflected back at him in the phone’s camera looked oddly familiar. The word alien came to mind, and clearly, he was like nothing else on earth. Some sort of a cross between a cat and a bug, if he had to guess. 

Despite the horrific transformation, Damien had to admit, the image staring back at him wasn’t that bad. Did it look almost…hot? D himself, he felt his cock getting hard in his shorts. Why was this making him horny? The scents wafting off his wet, furry body weren’t helping matters. Why did his body smell so nice?

A strange sensation assaulted his spine just then, as though it was extending out slightly from his backside. Yet, worst than that was the ache in his groin like his cock was getting hard and needy from the sights and scent of his changed form.  

Fear of the changes be damned. Damien needed to see it. His second set of arms stretched out without thinking and grasped the damp shorts, tearing them off his body with inhuman strength. He could clearly see the stub of a small moving tail but that wasn’t what had captured his attention. Before his eyes was a thick pink cock, still very human despite its added mass. Yet around the base pooled a blue flap of skin, not unlike the penis of an animal. And his furry blue balls were nestled tightly underneath, swelling with what he assumed to be alien seed. 

Damien couldn’t stand it any longer. His two new arms reached out, one teasing the shaft while the other played over his balls and taint. His other hands kept busy as well, playing over his still-present human nipples and running themselves over his well-toned visage. He wasn’t going to last long from multiple points of stimulation, and he was very eager to let himself go and experience all the pleasures of his new flesh. 

“GGGGGAAAAHHHHH…FFIUUUCCKKK!” Damien cried out in his high-pitched voice as his balls exploded and shot several streams of cum up from his engorged member, hitting him in the face and splattering all over his fur. His tongue snaked out and got a taste and Damien soon found himself wanting more. Though his mind was still in reverie from his release, his pink tongue darted out with surprising flexibility, rapidly cleaning all the cum off his soft blue fur. 

Damien came down from his orgasmic high slowly, cheeks flushed pink with embarrassment that he’d been out on the beach in plain view while masturbating. He picked up the discarded remnants of his shorts to try to save what modesty he could, though he didn’t need them with his cock hidden behind a well-hidden animal sheath now that its needs had been satisfied.

Giving his next move some careful thought, he decided it was safe to retrieve the canister, its effects on him seemingly already complete. Damien couldn’t help but contemplate the implications of what had occurred. Would that pink fluid have the same impact on someone else? He smiled at the thought as his cock grew hard once more. He was the only one of his new species, as best as he could tell. The idea of a mate seemed rather tempting…
