A story commission from back in February 2024 for https://www.furaffinity.net/user/lucasreturns/

Rykulf is tired and stressed from work, wishing for any excuse to just let it all go and no longer lean into human necessities. Fortunately for him, the shine of the moon from his window might have just what he needed...

A really specific commission for sure, real raunchy too.

Leaving The Past Behind

Rykulf spent his days indoors checking the calendar waiting for each day to pass by. Each day was another grueling wait for the clock to tick to the next day, eagerly awaiting the day he can finally be free. He was never a fan of daytime, it was the grace of the dark sky that brought him joy, a stellar audience with the spotlight of the bright moon shining down on him. He felt it welcomed him, but only under an appearance that came a few days a month. And it was finally that day.

But Rykulf was busy that night. So busy, he didn't even register the allure of the full shining moon filling his dimly lit living room. Though he could feel the heat of the room rising, the tension in his body increasing, he thought it was just another passing feeling, not noticing the growing hair on his arms. He got too caught up in work, work that paid him enough in hopes to escape the busy life of a human. If he missed this last bit of work due at midnight, the higher-ups wouldn't even bother looking his way. So he worked, and worked, until any part of his shirt that was touching his skin was borderline see-through. Not like there was much space in that shirt anyways, for Rykulf had a naturally sized body thanks to that monthly activity of his. And he was proud of it, every day after that eventful night checking himself out in the mirror and stretching out any clothes that dared to fit him previously. Each month growing in size to the point that even the XL clothes he bought struggled to fit him.

Rykulf groaned to himself, scratching his neck in hopes to get this work soon, when he realized his nails were sharper than before. Then, it hit him. With wide eyes and an eager grin, he leaped out of his chair and rushed towards the window. “Yes, finally!", he exclaimed as the shining visage of the moon reflected off his brightening eyes. The rumbling of his changing body spiked to an extreme heat, bringing a snarl out of him. The density of his muscles began to swell and compact itself, causing him to hunker down and lean against the wall next to the window in prime view of the moon. He couldn't get enough of it, he needed that spotlight to shine on him, to give him his real look. Rykulf watched his hands grow and reshape themselves, his bones shifting and forming into much stronger tools to hold his muscles. The muscles themselves fighting for space, each fiber tensing before expanding. He could feel his strength increasing with each passing second, drool trickling down his fanged smile, onto his thickening neck as his traps began to swell. His biceps and triceps both intensely throbbed as each movement of his sent jolts through his body, such a welcome feeling as he continued exclaiming his enjoyment of the transformation.

His clothes continued to try and hold him back, the strands of fabric fighting against his thickening muscle. But it was a fruitless endeavor, that drenched cloth showing off his increasingly sizable pecs beginning to barrel out of the V-shaped white tee while showing off the dense forest of fur forming between that cleavage and each bump of those chiseled abs. He took desperate breaths, trying to savor the feeling of his body forming to perfection, all while his mind began to cloud and he began to lose himself, his priorities no longer a matter to him. The growing beast looked behind him, raising his hands that were now strong paws with claws that could slash a metal door, lunging at his work desk. Sounds of metal and wood tearing to pieces echoed through the house's walls. He snarled and howled in joy, knowing his strength knew no bounds. He huffed and growled, realizing his sweat-drenched shirt still fought back against his magnificent growth, grabbing the hems of each fabric through those claws as they tore straight through.

Though his size was already big enough to rip holes in the sides, some of it still dared to hang on, not until he ripped them apart, showing off his steamy hide that, with the help of the moonlight behind him, quickly covered itself with dense fur matted with sweat instead. His back thickened and swelled, forming lats that would be confused with wings, spreading wide to make his back arch, the upper side of his back growing thick enough to form a topographic map. An intense sting ran through his body, his bones continuing to snap and reshape themselves throughout his body. His spine pushed out his backside, a tail squeezing over the top of his ripped pants while bulked calves tore the bottom. “Yeeesss… More strength… To replace this puny body!", the growing beast exclaimed to himself, looking at the mirror across the room at his magnificent form. He could see his expanding muscles flexing through his pathetic clothes, each slight movement being met with an immediate -RIIPP-. His shoes started to give way as well, the seams giving way and the laces being flung to the sides as his growing toes burst through. A glance down at his flexing paws was met with those steel black talons tearing through the measly seams. Drool trickled down his extending maw onto his fur-coated neck, his sharpening teeth containing a hungry gullet as he growled with shuddering hot breath visible in the cold night air of his living room. “Give me m-more…!", the beast roared as he turned to the moon, starting to pump up further and much faster.

The space in his pants was now close to nothing, an overwhelming pressure bringing a vicious -SNARRRL- out of him as his crotch extended and bulged out, bursting the sides of his pants to make room for the growing sheath and balls, the overbearing slosh of his nuts joining the cacophony of noises. Rykulf's eyes flared as each flex felt like lava coursing through his body that shaped into a bigger mass when he was done, each passing second an extra 20 pounds of sculpted beef being added to his perfect body. At this point, nothing was left of his shoes but very stretchy stained socks that kept the shape of his extending paws despite being riddled with holes, showing off the strength of bones more capable than steel beams. The crackling of his joints and bones adjusting to his bigger, better frame echoed on the walls. His pecs barreled outwards with each pulse, eventually preventing his view of his underside in short notice, reaching up and feeling those dense slabs of true masculine muscle and was met with orgasmic pleasure. He howled out loud as the sheath contained in the pre-coated briefs he sported underneath the vanishing jeans thickened to unnatural sizes. He could feel it fighting back, holding in a girth that any man couldn't even dream of owning. The growing wolf reached down and squeezed the thickening sheath with a now padded paw, howling once more as several ropes of clear musky output shot several feet in front of him. What was once heavy thick foreskin now forming into a fluffy shield for a monster length foreshadowing what was to come, a bright red tip spurting rope after rope of steaming hot translucent excitement causing a mess in his front, even spilling and staining on his torn socks that still conformed to his newly shifted feetpaws. Solid steel bones shaped up to hold up a 500 pound and growing beast. Even when tilting his head up to hear the reverb of his own masculine howls, he noticed that the ceiling wasn't too far away. Digging his claws into the wooden floor, the beast snarls and raised his thickening arms up to the ceiling, pushing against it and causing a web of cracks around his strong paws and a flurry of dust to fall around him, stretching those newly formed muscles and joints and refreshing his body with much needed blood. The feeling of his new body being capable of far more than that puny putrid human form intoxicated him. To Rykulf, there no longer was a need to turn back into a human.

Raising his arms allowed him to catch a whiff of the dense fog coming from the bushy forest in his pits, trickles of sweat coating his fur and reminding him of his status as an Alpha. No man on the planet could dream of looking or smelling as masculine as him, proudly sniffing and licking at his bulging throbbing biceps while nipping at the veins with his fangs that grew sharper by the second. He caught a view of his face in the reflection of the window, no longer carrying any appearance of his former self. “No… This IS the real me." He eagerly grasped at his sheath once more, his balls audibly groaning and filling out with another heavy load as his body heat increased, sweat drenching whatever fabric on his body that wasn't torn to shreds by the extreme growth or his own frustrations including his socks and briefs. Each pulse of growth brought a baritone rumbling growl from the shifted creature, his claws digging deeper into the weak wooden floor and marking it with the signs of his immense strength while his arms were busy pleasuring every inch of himself. His tail, now covered in fluff and swaying long and proud, swished from side to side in amusement of how incredible this body felt even to breathe in. The window grew foggy from his potent musk, the growing puddle of his pre-cum not helping with the intense smell of a truly masculine Alpha.

Rykulf's mind clouded from all the sensations and he slowly began to lose any cohesive thought, only thinking about his own body, what he would use it for, what others couldn't do that he could show off. The confinement of the house was getting to him, he needed to be free.

His instincts took over, his body filled with an intense rush of energy. With a quick glance at the window, he launched himself through, bursting through glass and wood with little to no damage at all. The strong hide and paw texture prevented any glass from hurting him. He left an impression in the frame around the window due to his sheer force, and the impact of his landing denting the roof of his porch, actually causing it to cave in. Such weak construction couldn't handle such a powerful beast. He landed through the second floor porch roof to the ground floor, denting the wood around his paws.

His ears flicked as he took in the many sounds of the night, not a soul outside to witness the makings of an Alpha, he had the night all to himself. The beast's body still growing and pulsing, he closed his eyes and took a deep breath in to let those strong new lungs relish the feeling of fresh, cold air. The blood in his body rejuvenating him and filling him with enough energy to let out a threateningly powerful howl, staring up at the bright yellow moon that shone down at him. Ten pounds, ten pounds, another ten pounds, his weight kept increasing as more and more bulk was added to his increasingly large body, each pump being accompanied with a heavy boomph. Thick veins wrapped around his muscles and pumped that potent wolf blood through him, even visible through his dense fur coat, removing any trace of the weak meager human body. At this point, he could barely see his length from under those mountainous pecs despite it getting longer and starting to protrude from the heavy sheath it rested in. His balls weighed down between his tree trunk thighs, needing to spread his legs to handle the heft of how much he was holding in. Everywhere he was left a trail of viscous, steamy pre-cum. It was impressive how the only thing that still survived on his immensely massive body was the gray boxers and socks, despite them being in shreds and holding on for dear life.

His arms shook, his solid arms growing stiffer and more dense, his bicep peaks threatening to clash with his fists. He needed to show off his strength. The beast eyed the car in front, craving to see the metal dented beyond repair. He raised his left leg up on the porch's railing, then with a thick flex he leaped off of it and onto the moist dew-covered ground, getting the remainder of his socks muddy as he took heavy steps towards the car. Despite such condensed fur, the growl in his chest was very audible. The beast was eager to lay waste to this useless junk of metal. Each splash of his paws on the mud sent specks of dark water up further to the remainder of his socks, coating them in more than his own output.

Finally reaching the vehicle, he let out a snarl as he stood up straight before leaning down, gripping the top of the car and denting the aluminum shell, his biceps and thighs beginning to bulge as his heart pounded much stronger. So much blood to focus in one area, these muscle groups visibly gaining size as the beast prepared his assault. He raised those pillars of muscle as sweat dripped off his fur, dealing a blow strong enough to break a steel pipe in half. The car almost looked like it was smashed with a machine, and not by a hungry beast craving more power. It was just the beginning. The night air was filled with snarls and metallic snapping, relentless pounding of his fists against various spots on the car, damaging thousands of dollars worth of machinery just for the fun of it. He loved how strong he felt, how strong he looked, how strong he was. Even while delivering the vicious beatdown, he continued bulking and making the vehicle creak and whine. Almost 10 feet in height, nearly 500 pounds of sheer muscle and growing from how much force he was outputting. The rush of destruction made his cock as hard as diamonds, each punch followed by a steamy rope of pre. His body continued to develop and thicken outwards, until he started to lose visibility under his barreling pecs. And when he eventually felt satisfied, he stood on top of the dented hood, not even a scratch on him while all that was left was scraps and shards scattered across the sidewalk and road. As a final blow to his prey, he kneeled down and gripped the top of the car. With one strong pull, he tore off the top. The action being so invigorating, he flexed his left foot's sock off, the dirty weak fabric falling to the side.

Holding the top of the car in both paws, he crushed it like it was a juice box, chucking it straight into another nearby car and caving a hole clean through. Realizing he was capable of more, he got down on the asphalt and bent down, frustratingly tearing off the useless remains of his boxers, his thighs once again throbbing to gain extra mass to hold up such a powerful frame as the squat allowed him to grab the front of the car. Effortlessly, he hoisted up the shattered chunk of junk and heaved desperately, launching it straight at his former home like an Olympic contestant. The heavy metal destroyed a majority of the top half of the human's house, fires starting to break out in the rubble.

Not that it mattered to him, it was no longer his concern. He was an Alpha, a predator of the night. And he was going to continue proving his might as he let out an eager howl that could be heard a neighborhood away.
