Walking out into the warm fall evening, Morghus stretched a little, loving the slight weight of the hoodie he had just bought. He had visited the second-hand shop on a whim, having passed it several times on his way home but never checked it out. He didn’t have a particular purpose for visiting, hoping on the off chance that something might catch his eye. Yet, the moment he set his sights on the lime-green hoodie, Morghus knew he had to have it. With a white collar, drawstrings, and a black stitched pocket at the front, its simplistic design was something that greatly appealed to his sensibilities. While he couldn’t be sure from at first glance, it really did seem like the hoodie would be the perfect fit for him as he brought it up to the cashier. Allowed to try it on, the clerk confirmed what Morghus had hoped, grinning a little as though he was in on some joke Morghus was unaware of it. He hardly cared, however, elated as he left the store, smiling from ear to ear.

While he usually didn’t mind his walk home, this late afternoon was the perfect setting for a longer trip. The sun was low on the horizon, and while it was warm for early September, a cool breeze played over his head, teasing through his hair and making him adjust his headphones. There was a skip in his step as he took the longer route through a wooded path. It was one enjoyed frequently though was particularly lovely with the changing colors and the smattering of leaves that had already fallen. There was no rush to get home, and little for him to do than to enjoy how well his hoodie fit and how good he looked in it. In truth, he’d been looking for something akin to this for months, and now was the perfect season for it!

Focused as he was on the world around him, Morghus hardly noticed a tickle at his ears, as though something had gotten caught within them. They slowly felt warmer than the rest of his body, though at first, he figured he was imagining things. It wasn’t until his headphones became loose that he reached up to touch them, a little confused by the sensation of soft hairs his fingers detected. The inside of his ears was larger than he was used to, and a steady itching brought his attention to a series of long, sensitive hairs that had not been present before. Rubbing the outsides reported tightly formed hairs all over, spreading at his touch and leaving him alarmed by what he was feeling. The flesh continued to overheat, malleable as it expanded at his touch. It was hard to say without a mirror, though they seemed significantly larger, the bases expanding up the sides of his head. Worse of all was the stirring of muscles underneath that drew his hand down. The moment he reached them, his ears started to twitch, making him leap up in terror. The soft fuzz, massive canals, and moving ears were something that belonged to an animal!

Confusion raced through his mind as the strange heat started playing through his hand. Akin to what he had experienced over his ears, Morghus felt his heart race, scared at the implication. Raising it with some concern, it seemed his fingers were getting longer, a few cracks popping through them as though the joints within were breaking apart and reforming. Three fingers were changing, growing steadily longer, while his pinky seemed stationary, and his thumb twitched in irritation. While the individual segments stayed intact, they were already much longer than humanly possible. As much as he wanted to keep them still, the slight heat made them tremble, and it was all Morghus could do to hold his arm steady as his fingers continued to extend, twice their human length and longer still.

Pressure at the tip of each caused him to yelp, though it wasn’t quite painful. It was still alarming to perceive the cuticles of his nails expanding into the tips, pushing out into a semblance of claws. They were somewhat blunt, though rather long as they surrounded the tips and spread outward. Feeling heavy, Morghus tried his best to twitch the fingers, finding it troublesome with the unwieldy joints. His thumb, too, was adorned with the same pointed nail, though it remained relatively the same size. His pinky, however, seemed to twitch with a death throw, immobile as the bones and tendons were absorbed entirely. Such was a little alarming, though hardly the strangest thing about the changes. Their steady progress left him to stare at fingers that were now close to the length of his lower legs and still growing slightly.

Yet, nothing thus far was stranger than the warmth that started to work its way from between his fingers. As though small pliers were being used to pull at the skin, a warm, thin layer was drawn upward between each, crawling up each side of the fingers and causing a peculiar tingling that annoyed him to no end. The skin was not translucent, though paper thin as it continued to separate, reaching toward the tips. As best he could tell, the membrane was warm, its surface peppered with veins that he could see as he held them up toward the setting sun. Part of him wanted to touch it, though Morghus found himself worried such might spread the changes. He could only watch the skin-shaded membrane move toward his fingertips, effectively sticking them together. As unwieldy as his fingers were, the membrane between restricted their motions further, Morghus reflexively twitching them to try and work out the kinks and rediscover the level of mobility they now possessed. 

Stunned by their development, Morghus was barely aware of the itching overcoming them, spreading down the back of his hands and playing up the fingers. It was pitch black, filling the skin like a pitcher of liquid as it covered every inch he could see. The itching was not simply from the shifting skin, however, but from a peppering of what he could see was short black fur. It continued to steadily move up his hand, even over his wrists as the skin of his membrane turned black as well. Even his shoulders began to itch, Morghus trying to look down to see that short patches of brown, not black were poking from the skin. It took him some moments to put two and two together, but as best he could tell, he was turning into some sort of creature!

His thumbs, now black and sporting a similar claw to his other fingers, remained relatively the same size and were still able to move the way he was used to. Yet, the same tugging on his skin soon swelled from the base, moving toward their rounded edge. While much smaller than the webbing that had spread up his fingers, it was still present, making him wonder if he had the basis of some sort of wing. Flexing the fingers once more, Morghus found he almost enjoyed the tugging sensation, finding it alien yet fascinating. He was surprised to find his fingers and thumb maintained the same number of joints, and even their restrictive movement was functional, if not perplexing.

Eventually, the temptation to touch them with his other hand became too great, and Morghus couldn’t help but run his other fingers over the sensitive flesh. It was pleasantly warm, sending a shiver through his body. As much as he wanted to deny it, the membranous flesh was clearly part of him now. His fingers, too, felt strange, long, and gangly though were clearly part of his anatomy. The fur was pleasantly soft to his touch, and there was a part of him that worried for his future. Still, there was obviously nothing he could do as his fingers finished their growth, becoming some sort of wing hand that, on another creature, might allow him to fly.

The same peeling sensation soon started to work its way from his armpit, leaving him to lift it with some confusion. Thankful the hoodie was sleeveless, it felt bizarre to witness the skin of his lower arm and body forming the same connective tissue, the goal of reaching his closest finger obvious. Part of him wondered what would happen as the skin from his sides pulled out against his hoodie, and he reflexively reached with his one functional hand to pull it off. Yet, he was startled to discover the seam of the hoodie was inclined to part directly along the path of his forming membrane. It alarmed him to think the hoodie was the cause of the change, and Morghus figured it was best to remove it. Still, with only one arm functional, such was impossible, and he was forced to feel the membrane spread all the way down his side toward his pelvis and reach up his arm toward the tip of his closest finger. 

Soon, the tingling of his spreading membrane seemed to cease, and Morghus was left with what functionally looked like a bat’s wing. Having never seen something up close, he was a little alarmed, especially since it was part of his person now. Even the skin around the other side of his elbow was prompted to form another thin membrane between itself, stabilizing his movements. While he had little frame of reference, it seemed his arm was totally a wing now, much larger than a bat or similar creature. Without knowledge of what the end goal was, he was left to shudder, sure the process was not yet done with. Still, even the fear of what was happening could not entirely dissuade his intrigue, something about the form was oddly appealing. And Morghus was remiss for not wondering what was to happen next!

In his confusion over his newly formed appendage, the start of a tingling over his other hand almost went unnoticed. A tremble of fear ran through him as he raised his other hand, the same thing happening just as he’d feared. Yet, there was something almost exhilarating about the prospect, something he couldn’t entirely deny. It was as though he longed to possess wing hands, the sensation of webbing between them natural. Knowing what was to happen to him, Morghus almost longed for the stretching of his fingers, the delightful pops, and cracks of his lengthening joints ringing in his longer ears. This time, the sensation of his claws erupting from the tips was welcome, as was the loss of his pinky. It was all a prelude for what was to come, and he twitched the longer fingers with delight, as though encouraging the membranous webbing to grow, tugging at the other digits as they stretched further apart than humanly possible. And as it spread to the tips of the fingers, Morghus could only part them in delight, comparing their contours with that of his fully changed hand and eager for his left to look the same as his right!

By now, the sensation of membrane forming from his underarms was familiar and almost pleasant. It was amazing his former hoodie was able to part to allow it to stick to his increasingly furry skin. Soon, it ran all the way down to his sides, and yet the hoodie was in no way hindered, as though the fabric was designed to alter that way. It was not enough to distract from the warmth of membranous growth, and he was delighted to have it reach the tip of his final claw. Unfurling the pair of them, Morghus felt something akin to delight, thinking how such assets would work to aid him in flight. Best of all, his fully formed membranes had no negative effect on his new hoodie, leaving it relatively intact. By the time it was finished, the parted sides seemed more akin to a poncho, though Morghus could hardly find fault in its own transformation. In some ways, it looked even better like this!

Holding his twin bat-like wings with wonderment, Morghus was largely ignorant of the continued itching over his skin, playing under his collar and down his poncho. As best he could tell, it was a similar brown shade to what had sprouted from his shoulders. Yet, with his hands in their current state, he had no ability to pull it off. A part of him concluded the poncho was the only thing that could have caused the change, and Morghus was forced to allow it to conclude, regardless of its eventual outcome. While it was hard to perceive under the poncho, it seemed his brown fur was layered, a long silky overcoat with a soft underlayer. A part of him wished he could expose the lovely fur underneath. Yet, even if he was able to remove his poncho, the idea didn’t sit with him, like it was part of him now. Regardless of what would happen to him, he needed to keep it on, truly being the perfect fit for him!

All the while, the brown fur had been spreading over his back and down his shoulders, changing to black as it reached his groin. It itched around his private parts, and Morghus did his best to suppress a groan. He didn’t want to think about what was happening there, though much to his embarrassment, his shrinking waist might soon expose him. The sensations were only exacerbated by pressure from within his spine, as though it was extending against his pants. While not painful, it was extremely uncomfortable to feel it confined, Morghus now wishing he could pull down his pants despite himself. Yet, his thinner waist soon solved that problem, and his pants fell down, leaving him naked below his poncho. 

It was hardly the relief he was hoping for, the cool air on his fur making him shiver. Kicking his pants and underwear over his shoes, Morghus felt the itching spreading from his groin toward his legs. They were growing thinner, though more muscled, tensing as the skin became covered with bat fur. But it was the growth out of his backside that truly had him perplexed, and he looked backward with a sense of shock. Over an inch now and continuing to expand, it looked to all the world like a tail, one that was extending down the length of his legs. It soon became covered with black fur as well, thicker to match the coat that covered his chest and back. Strangest, perhaps, was that if he focused on the tail, it started to twitch, Morghus slowly more fascinated by exploring it than fearful he had one. Was it really the type of tail that a bat would possess? It reminded him more of a fictional dragon, with a thick fluffy mane of black fur down its back all the way to the tip. Regardless of its design, Morghus was quickly enamored with it, wagging with enthusiasm from owning something completely unknown to the human him. 

Still, as the same membranous tissue started to stretch below his ass, Morghus was once more reminded that he might be turning into a bat creature. It was strange having every appendage connected by this webbing, restricting the motion of even his new tail. Feeling it merge with the skin of his inner thigh was one thing, both sides connecting down toward the base of the tail’s pointed tip. But as the membrane stretched to merge his tights with what had become of his hands, Morghus found himself eager to explore how everything worked now. Above all, he found himself wondering if the changes would allow him the vaunted reality of flight!

The alterations within his chest, while discomforting, were somewhat anticipated, if only that they might aid with his newly discovered goal. He was shrinking, though only slightly, giving credence to a body that would remain as much human as a bat. Yet, thankfully, his poncho seemed to shrink along with him, enough that it remained the perfect fit for him. It was bizarre, though little about the scenario made sense, and he was simply left to delight in the changes. It was uncomfortable feeling his guts gurgling, internal organs altering for his slightly smaller frame. An increased tension in his muscles made him delighted, however, providing a strength he had never known. He was lean but toned even under his fur and poncho. If only he could rub it to discover for himself! 

All the while, a steady ache emanated from his body, cracks from within that should have been rather painful. Morghus had to wonder if his bones were shifting, parts breaking off as a way to reduce their weight. Surely, hollow indents would be required to lighten them for flight, though he hardly had any idea of what that might mean for his current body. He certainly felt a little lighter and was eager to try jumping in the air. Be it a combination of his added muscles or lighter bones, it was so much easier, and he felt his heart flutter at the notion of being able to fly. It was scary, to be sure, but it seemed that was the purpose of his new body and something he would be eager to experiment with as the changes cemented themselves. 

While his groin hair had largely converted to fur at this point, Morghus was a little alarmed to feel a tugging over his flaccid cock, as though his foreskin was being drawn toward his groin. The fur around the area was white, a sign white fur was likely coating his chest where he could not easily see. As a peppering of white played over its surface, Morghus let out a moan, the sensation uncomfortable and making him wish to reach down and tend to it. Looking down, it seemed his foreskin had deepened enough that it subsumed the entire shaft, though the head was still somewhat visible. Much to his disappointment, it seemed to be shrinking somewhat, though, against the cascade of changes overcoming him, Morghus found it hard to really bemoan a reduction to his maleness. Even as the tip tapered or the shade began to darken to black, Morghus couldn’t bring himself to concern himself with it too much. While slightly curious, he resisted the urge to explore it further, unsure how to safely do so with his new arms. 

As much as the changes to his member should have disturbed him, a surge of arousal slowly began to flush through him, causing him to moan once more. The cadence of his voice, while higher pitched than usual, was ignored over the intense lust creeping through his mind. While Morghus found the changes rather fetching, there was nothing inherently sexual about the process. Yet, there was no denying his sudden burning desire. All he could do was moan as his penis drew its way from his black-furred sheath, the sensation sensual all on its own. 

Staring down at what became of his shaft, Morghus was a little taken aback by its uniform length, his long, thin penis pulling his new sheath down around its base. Not sure how to really work his wing hands, he was still able to maneuver his arm downward and hitched his clawed thumb into the sheath, the sensation making him shiver. Be it a facet of the change or his own lust coming to the surface, Morghus felt more pleasure from teasing his cock than he could recall in recent memory. Holding his claw against his sheath was pleasant on its own, but it was soon obvious he needed more. 

Holding his other wing down, his longer cock was easily able to brush against his warm membrane, causing him to shudder. While he wasn’t able to envelop it fully, the touch of such a treasured bodily addition was more stimulating than he could have anticipated. Without thinking, he was quick to start thrusting his hips against it, lightly moaning from the sensation. The tension in his bobbing bat testicles grew rapidly, and it was obvious he wasn’t able to last long. A fleeting facet of his mind assumed that bats might not have the longest sexual encounters, smaller mammals as they were. Yet, in the heat of the moment, he was remiss to care, feeling his testicles swelling and preparing to spill his load. It came all too quickly, cock head rubbing frantically against his membrane and creating exquisite friction. Unable to stifle a moan, Morghus felt himself falling over the edge, spilling a modest load of cum from his blackened cock tip and coating his wing hand in sticky seed. It took him a few moments of panting to get his barrings, not even minding the sensation of drying cum that he could not wipe off. Just as quickly as it had come to arousal, his damp cock head slid back into its warm home, hitching back against his groin for the next time he would use it. 

By this point, fur had spread all the way down his legs, and a tingling in his feet made him certain they were the next thing to alter. Without hands, there was no way for him to remove his shoes, and he was forced to feel the digits expanding within. While not painful, it was uncomfortable to feel them pushing against the fabric, twitching them reflexively as their joints elongated. Hardly the length of his fingers, similar claws soon worked their way from the nail beds and surrounded the tips. It seemed they were sharp enough to pierce the leather, and Morghus was quick to twitch them, wanting to work away the fragments of his shoes. Rather than concerned, he was eager to be rid of them, figuring he would no longer need them for his new form. Black fur had peppered the backs of his feet, and as the ends of his shoes popped apart, lengthening heels forced him into a digitigrade stance. It was a bit awkward standing there, though as he balanced with his leaner body, Morghus found it somewhat preferable. His walking gait was hardly impeded by this point, easily stepping over the fragments of shoes and socks as he did so. 

Eager for what the changes would eventually bring, an itching over his hair made him wish to reach up and touch it. The formerly dark human hair ran down to his brown-furred shoulders, tickling the back of his neck as it erupted into bat fur. As best he could see out of his periphery, the bat fur that adorned his hair was white, turning brown as it flowed down toward his back. Soft white fur ran up his neck, converting his beard hair as it ran up along his sideburns. It itched like mad, though Morghus had no safe way to scratch. It mattered little, Morghus figuring that it would be over in a few minutes and he would be granted a desirable bat visage. 

Even though he was expecting it, it was still a little jarring to feel the pops of his jaw as it steadily pushed outward. The bones seemed to crack and extend only a few seconds before the muscle stretched to keep up. It only took a few moments for him to be able to see it in front of his face, making him squint his discomfort. The altered muscles within his jaw allowed it to open somewhat wider, Morghus reaching around with his tongue to get used to it. Gums itched as his teeth altered, their edges largely human though adjusted for his new diet. What kind of bat was his new form based on, anyway? The more canine-shaped muzzle denoted something more vegan, a flying fox, perhaps. Once more he longed for a mirror to admire his new self, figuring he might look rather cute, all things considered!

The sensation of his nose stretching left him to reach up, sneezing a little as he explored the moist, black leathery skin he now possessed. Widening nostrils drank in his own scent, rich and sweaty from the change. It was strange to feel them expand wide enough that breathing was easier, and his mouth drew in a plethora of scents that evaded the human him. Above all, the scent of fruit, growing apples on some of the nearby trees made him salivate. That, in tandem with his canine muzzle and broad teeth, confirmed the mental image of a flying fox. An animal he held in some reverence, though not one he had thought of in some years. He would certainly think of them now every time he looked in the mirror!

While nothing about the change was inherently painful, it was still uncomfortable to perceive his skull shifting, frontal bones altering to allow his muzzle to extend further. The compression against his eye sockets caused them to water a little, and he blinked a few times, hoping his eyesight wouldn’t shift too much. Thankfully, when the discomfort passed, he was still able to view the world in somewhat of the colorful pallet he was used to. While he was barely aware of it, the color of his eyes was now golden, more suited for the creature he had become. While his skull was warping, it didn’t seem that anything had fundamentally changed within his mind, as best he could tell. If he was a flying fox, his demeanor would be more akin to a puppy than anything dangerous, and while things like a newfound desire for fruit were present, there didn’t seem to be much in the way of invasive instincts. Aside from feeling his flicking ears moving toward the top of his head, there didn’t seem to be much left to alter. And such was thankful, given his desire to look at the changes from his own perspective. 

As best he could tell, the transformation was done with him, leaving him a human-sized bat, albeit a little shorter than he was used to. Yet, all he could think to do was to giggle, elated that the poncho was still the perfect fit for him. It even allowed enough air to pass through the sides so that he wasn’t overheated with all his fur! Even if he had the hands to take it off, he couldn’t bring himself to remove it. Perhaps it had some magical hold over him, a conduit for the changes and the reason for his initial draw to it. It didn’t matter anymore, he reasoned. It was part of him now, and as he walked forward, Morghus longed only for a mirror to admire himself. 

Strangely, throughout the entire transformation, no one had come across him, or even used the trail he had been walking on. As he looked around, a myriad of scents crossed his nose, enough that he was nearly overwhelmed. As many odors escaped him, he was at least able to determine nothing like him, or his former human form had walked on the trail over the last day. He was left to delight in his new olfactory abilities, trying with some success to identify things that had escaped his human awareness. Clearly, the species of bat he was based on had a superior sense of smell and likely needed it to find fruit from miles away. Either way, it was obvious to him that humans really were so limited in their abilities to smell!

Better yet, perhaps, was his ability to hear, bat ears like radar as he swept them this way and that. There was no one for miles, as best he could tell. While his auditory senses were far beyond his humanity, Morghus realized he had no ability to detect the ultrasonic notes that he assumed other species of bats were born with. It mattered little, he figured. His new body was based on a more diurnal species, though his eyes could make out the oncoming night with a decent level of acuity. It was preferable that way, he figured, more natural to his human habits than that of a nocturnal insectivor. Switching to a diet of fruits and sweets was hardly an inconvenience for the gift of this new form!

With the changes done, a part of him felt a little nervous about being in the open as he was. Would other people understand his form? To his surprise, his heart was beating at a much faster rate than he was used to, as though he was hyped up on some drug. It took him a few moments for him to consider it might be a bat thing, that a higher heart rate might be necessary for flying. At least he didn’t experience any pressure in his chest or the like, but rather a growing sense of energy that he simply needed to expel. And there was no time like the present, Morghus looking to the darkening sky with longing. He didn’t know how to fly, and couldn’t have known from a human perspective. Yet, the stirrings within his mind seemed to have an idea, and all he had to do was let himself relax and do what came naturally. What was natural for his new body was to take to the sky!

Eagerly jumping into the air, Morghus was shocked that when he lifted his arms upward, they were able to rapidly unfurl and catch the air to draw it underneath. Moving them in rapid succession, Morghus found it more akin to swimming in the air, loving the sensation. It was beyond his expectations, his lighter bones and smaller frame able to make it through the air with ease. Even his poncho wasn’t heavy enough to hinder him as he took to the night sky as though he belonged there. As he passed above the forest and toward the town beyond, all Morghus could think was that his purchase truly was the perfect fit for him!
