Scott is a werewolf, and on the night of his monthly transformation, he forgets to use the bathroom, only to discover how much better it is to go when you're a wolf...


BEEP BEEP BEEP.

11:55pm.

Scott was in the middle of his college work when the calendar app on his phone began to blare. He swiftly pressed off on it and stretched in his chair as he saved his work and turned off his laptop.

“Alright, I’m gonna turn in five minutes…”

The young man, about 21 years old, was an average, albeit muscular figure. He had scraggly brown hair, a set of thick chest pecs and a scruffy amount of facial hair. He was also a werewolf, and tonight was the monthly full moon. Having been a werewolf most of his life made him pretty good at planning things out; he always made sure he had no engagements on full moon nights and made absolutely clear to all of his friends that he wasn’t available. It had almost become routine: Scott was pretty much adjusted to the process to the point where the event mostly had become mundane.

He stood up, turning off his computer and prepared to head for his bedroom to wait out the transformation when suddenly his gut rumbled.

Grrrgggll…

Scott stood there, for a moment unsure of what the sensation was when his belly growled again and he suddenly grunted as he felt a wave of pressure down there.

“Oh goddamn it, why now of all times?!”

It would be 5 minutes until his transformation, did he have enough time to use the bathroom? In an odd bit of fate dodging, Scott had never had to go before as a werewolf, and he chastised himself for not having the forsense to go beforehand. The pain in his gut grew again as he looked at his phone again: 11:56pm.

“Alright, I have to be super quick about it!”

Bolting straight for the bathroom, Scott was already shedding his pants and his shirt--there have been numerous times where he had forgotten to strip down before he turned, resulting in the loss of a decent number of shirts, boxers and pants. By the time he had made it to the door, he was already fully naked and nearly leapt onto the toilet seat. He still had three minutes before midnight.

The young man began to grunt and groan on the toilet seat, at first feeling the mess in his asshole shifting as he began to crown. Scott huffed, sweating and panting as the blood in his veins began to grow warmer, the first tell sign that his transformation was merely moments away.

PPPFFFFT! FFFRT! PLLBT! POOOT!

At first, things seemed to be moving, his asshole was puffing out gas. Scott panted with relief as the farts ripped across his hole, echoing in the bowl. The man huffed and pushed harder, feeling a stream of piss spraying into the bowl. The mess began to excrete, and Scott let out an almost wolfish breath of relief as his bowel movement began in earnest.

It was typical of most of his trips to the bathroom, only this time he was running under the clock. His cock managed to relieve a bit of the urine from his bladder, while a few more turds slipped into the toilet water below.

“Come on, come on,” he moaned, straining to work out the mess. He glanced at his phone: 11:58, he was cutting it really close. Scott held onto the sides of the seat and forced as hard as he could, hoping he could finish his business before the clock struck. It was pretty hard to relax when the looming threat of becoming a wolf was mere moments away. After a minute of straining and pushing on the toilet, Scott suddenly felt the overwhelming telltale signs of incoming transformation. He looked outside of the bathroom window: the full moon was glowing brightly in the night sky.

12:00am.

Scott growled in frustration, “Goddamn it I didn’t get to finish goooooooaaawwwwwooo!”

Scott let out a huffy breath; he had been through this many times but the sensations always managed to get to him. His canines began to sharpen as his tongue grew longer and flatter in his mouth, lolling out as he began to pant. Even though his transformation was already underway, he still continued to push and drop logs into the bowl.

Sweat began pouring from his face as his body was now changing much faster. He could see his nose flattening out into a snout as his ears pointed and moved up his head, ending when his entire nose and jawline pulled out and stretched into a muzzle. Even though he couldn’t see them; he knew that his normal brown eyes instantly turned into a shade of bright yellow and his pupils became slits. Scott looked at his hands: they were quickly morphing before his eyes as his nails extended out into sharp, black claws. Fur began to sprout from his groin area as his pubic hair changed into coarse, brown fur, spreading across his skin. From within his voice box, a guttural howl came out.

“Arrggwwooooooo!!”

The changing werewolf groaned as the skin on his arms and legs prickled as Scott’s muscular torso began expanding even more. His already ripped pecs grew even more defined as he bulked up to nearly twice as big as he usually was. The muscles in his toned forearms and thighs bulged out, gaining even more definition as his entire body swelled up. The brown hair ran down his arms, covering his fair skin with the fur coating of a wolf. Scott’s human cock, uncircumcised and girthy, began to change too as the foreskin morphed into a sheath, his balls dropped as the fur overtook his scrotum as penis became a dark red and grew a pointed tip,he accidentally shot a stream of piss that hit the wall and began to run down it onto the floor. It was a good thing he was already naked: many old outfits were shredded by the sheer mass of his body, but he had grown comfortable transforming in the nude.

The changing human’s ass, still quivering from his untaken shit, puffed out to nearly double its size, his ass cheeks resembling water balloons as they wobbled, the brown spreading fur covering them as his tail snaked its way out from his tailbone. It was long and hairy, and began to wag as Scott was soon able to control its movements. The changes to his ass made his colon expand as more gas started to come out. His tail suddenly lifted straight up and--

PPPRRRFFFFFFFBT!

He felt a blush run across his cheeks as that had been the first time he farted as a werewolf: and for some reason it felt much more sensual than it had when he was a human. It felt…really good. Scott managed to squeeze out another lump before a final crick of his spine fully locked and he fell forwards off the toilet and forward onto all fours. Scott let out a long howl as his werewolf transformation completed.

“ARRRRWWWWWWWWWWWWWOOOOOOOOOOO!”

The neighbors had heard his wolf howls on occasion, but Scott had always dismissed them as coming from a dog. But, here he was, fully transformed into a brown werewolf, nearly twice as bulky and muscular as he had been as a human. He sat on the floor of his bathroom, looking at his toilet and trying not to sniff too much: he could smell the unflushed mess he left in it much more strongly with his canine nose. Scott winced as his bladder called out to him again and his stomach gurgled--he still had a lot left in him. This was an issue: with his feral body he could no longer sit on the toilet properly, most likely it’d get everywhere and it would be a pain to clean up after himself when he reverted back.

GRRGGGLL!

A dog-like whimper escaped Scott’s lips as the urge grew much stronger, he had to do something or he could piss and shit himself right now. Getting on all fours, the wolf quickly made his way out of his bathroom and out towards his living room. Sweat began to bead down his furry head as he considered his options: he could do it on newspaper, but that wouldn’t account for the piss, and with his cock now a wolf’s, he couldn’t aim for a plant either. His stomach growled again, and soon urine began to leak from the tip--there was only one option in this case: he had to go outside.

Scott had never gone outside as a werewolf; he always rode out the full moon in the comfort of his own bed, mostly sleeping. Still, given his preparations, he had the backdoor of his home fitted with a hidden doggy door in case of emergencies. His claws scraping against the wooden floors, the wolf scrambled to make it to the door to the yard. Scott had the dog door disguised as part of the design of the frame, and he could push it out by unlocking it with a button that he could easily push even as a wolf. He pressed his pad against the button, allowing the door to swing out as he got his thick and hairy body through the opening.

The full moon shone quite brightly in the sky, illuminating everything in his backyard in a transcendent glow. The night air was cool, and the smells of both the plant life that grew as well as the various scents of the neighborhood filled Scott’s nose. Scents always grew stronger while he was a werewolf, which is why he tended to avoid going outside: the different smells could overwhelm him. Plus, none of his neighbors knew he was a werewolf, and by chance if they saw him like this it could spell trouble.

There was a big oak tree that grew in his yard; it had been there when he had first moved in. He quickly shot a look around, but nobody was out at this hour. Unable to hold back the flood any longer, Scott sidled up to the base of the roots, sniffing at the scent of wet grass and peet before he turned around and lifted his hindleg up high.

PSSSSSSHHHHHHHHHHHHHH!!!!

A tsunami of urine began to spray out of his wolf cock, splashing onto the tree with the force of a firehose. Scott nearly howled right there: this felt wonderful! He had never relieved himself while in werewolf form, but the sensation of the piss flowing from his throbbing canid cock was something he had never known could feel so good! His tongue lolled out and an almost glazed look washed over his face as the urine surged from his member: hosing down the entire base of the tree. It was way more than he would’ve excreted as a human, but as a werewolf the amount had nearly tripled. His bladder tingled in his body, as if it were pleasantly reacted to being drained. As the stream of pee slowly reduced down to a trickle, Scott was overcome with mind-melding relief, still panting, with his hind leg lifted high up. The entire tree was soaked in the musky smell of wolf urine, the scent invading his sensitive nose and contributing to the intoxicating sensation of it all.

The wolf’s stomach gurgled again, snapping Scott out of his trance. His tail lifted again and another rippling fart burst out. He brought his leg back down as his body lowered down into a doggy squat. He shifted his legs apart, raising his tail again and panting hard as now the rest of the shit was allowed to come out.

PPPRRRRFFBBBT! PLLLBBT! SPPLAT!

A pleasant rumble flowed through Scott’s lower gut as the mess he had been holding back was allowed to flow free once more. Though he had passed modestly sized logs while human, now the turd was thicker than an arm. His anus was stretched wide, his pants and huffs becoming more pronounced as the shit landed in the grass with a wet sloppy thud. Scott whimpered in pleasure, the more sulfurous, almost earthy scent of his own poop wafting into his canine nose, mixing with the scent of piss that soaked the tree. He felt his cock sliding out of its sheath, dripping eagerly as his prostate was softly situated by this incredible bowel movement.

The moon seemed to glow brighter as the werewolf spread his legs apart wider and began growling under his breath as he forced his glutes to push harder. The muscular strength Scott usually gained as a wolf all went down to his toned buttocks as he began pooping for the first time as a werewolf. Long, hefty and chunky turds squeezed out of his hole and began to thump and splat onto the grass, curling and piling on top of each other. The muscular canine was awash in a mixture of grunting, whining, moaning and panting as he passed log after log. His ears picked up the sounds he was making, and somehow it drove his arousal even more. The few turds he had passed as a human seemed like minor twigs compared to the massive logs he was defecating out now. The shit was coming out much messier now: his anus sputtered with leftover flatulence as more of the sloppy shit began pouring onto the grass, making a colossal mound that quickly grew so tall that he could feel it squishing against his dangling nutsack, while his throbbing wolf cock was swollen in a full blown erection.

Without controlling it, Scott’s tail began to wag! He was enjoying all of this: urination and defecation as a werewolf was something he’d never considered before. It was so much more sensual than it was while he was a human and with his body changing he produced nearly twice as much as he could normally. He turned around to stare at the mess that he had made: the gargantuan pile of poop eclipsed anything he could even manage in his human form, standing nearly a foot high and looking as if twenty dogs had put their butts together and pushed it all out. On instinct, the werewolf turned around and kicked some dirt onto the pile, as if he wanted to bury it much like a dog would. The stink that both the pile and the piss stain let off invaded his sensitive wolf nose, driving his arousal tenfold as the warm shit smell made something in his brain snap.

He was so horny, he needed to hump something immediately.

The werewolf bounded over to the tree he had soiled with wolf urine, and began to grind his giant wolf cock against it. He mounted the tree, imagining it to be a sexy man, as he ground and thrust against a knothole.

“HHHRWAAARRROOOOOOOO!”

The howl he let out as he came broke through the dead air of the night was something he’d never do if he were more in control of himself. In fact, he swore he saw the bedroom light of his neighbor's house turning on and a figure peering out of it. It didn’t matter, because after a few more seconds he came: humping viciously as his cock spurting hot wolf spunk all over the tree, glazing the bark.

Even as he dismounted, his cock still throbbed with need. The canine slipped back into his house through the secret doggy door, sniffing around for more things to hump against. Normally he would spend the majority of his wolf hours sleeping curled up in bed, but there was too much sexual energy he needed to be relieved of. The werewolf stared at his pillow, catching the smell of his own sweat and body odor. He pounced onto the bed, pulling his pillow into his body and biting onto it as if he were biting the neck of a handsome beta wolf. He began humping much faster now, grinding his cock into the clutches of the pillow, imagining the smell of shit and piss as he let out another long fart.

PPPBBBBBHHHHHHHTTT!

The gas ripping against his prostate was too much, and with his humping growing faster and faster, the wolf blew his load for a second time. The cum splattered all over the pillow, getting on the sheets, blanket, mattress and his fur, but he didn’t care. The orgasm did nothing to abate the arousal flowing through the canine’s bloodstream, as his cock once again swelled up into a stiff erection. He bit down on the pillow harder as he went for another round of humping, as the full moon shone on him brightly through the window…


BEEP! BEEP! BEEP!

Scott groggily opened his eyes as the morning sun shone into his eyes. He was fully naked, laying on his back on his mattress in his bedroom. He lifted his hand to his face: it was human shaped once again. He had reverted back to normal in his sleep.

The moment he tried to sit up, he knew something was different. A sticky, dried up substance was covering his entire body, to the point his sheets were stuck to his skin. Scott peeled himself out of bed and realized that the substance was dried cum. There was an uncomfortable lump in his back, and he noticed the pillow he had slept on funny: it was nearly frozen stiff with dried semen, battered and beat up with teeth marks all over it.

“Ugh, the hell is all this…?”

Scott headed to the bathroom to shower himself off; what the hell had happened last night? He remembered turning in the bathroom, using the secret doggy door to outside, and going into the yard before his memory became a blur.

The first thing he noticed when he opened the bathroom door was the unflushed mess he had left in the toilet. He quickly flushed it before showering himself off; he was sweaty and cum stained and still confused.

“What the heck did I do last night…?”

Once properly cleaned off, he slipped on a fresh set of clothing and his jacket before bundling up his sheets, blankets and pillow to take them to the laundromat. On the way out, he caught a glimpse of his yard and he turned red. The stinking pile of shit that he had passed last night was right there in the center of the yard underneath the tree which was still stained with his musky wolf piss. It was much bigger and messier than he remembered and the size of it impressed him. That’s when it all came back: the pissing, the shitting, the multiple hump sessions. Scott chuckled with both embarrassment and amusement as he took note to clean it up later.

As he left his home to get to the laundromat, one of his neighbors spotted him.

“Hey Scott, you really shouldn’t be letting your dog out after midnight, some of us are trying to sleep and we could hear it howling.”

Scott laughed good-naturedly, promising to keep the “dog” inside for the night as he began driving to the laundromat. While his sheets tumbled and rolled in the washer, the werewolf smiled as he checked his phone for the date of the next full moon.

He would eat a big dinner that night, and buy himself a muzzle before then. Because the next time he turned, he wanted to make his shit pile even bigger, and he needed something to keep himself from howling in rapture…
