“No! Pleas- Ack…! I can still repay the d-debt!” – Larry said while being pinned to the wall by two thugs in a forgotten alleyway. They looked at each other and quickly deemed Larry not to be credible. “You d-don’t- Agh!” – Larry was interrupted by a punch to his stomach which forced him to bend over and fall over from his other captor’s grasp. “Yes, we do. You had a chance to pay up in time. Now your time’s up, literally.” – The taller thug said plainly. Larry got onto all fours, realising that if he got up he’d get punched again. “So w-what are you going to do to me, just kill me…?” – He muttered genuinely afraid this time. The shorter thug pulled out something out of his bag. After a while it became clearer that it was some sort of an injector, looking almost like a syringe, but more futuristic. Before Larry had a chance to stammer again he got jabbed with the in the neck.

“Ow! F-What was in i-it? What’s going to happen to me now…?!” – Larry questioned his captors pathetically. He immediately jerked back, but the liquid was already in his bloodstream. The taller goon shook his head and pulled out some thick scissors out of his bag. Larry felt weirdly itchy all over, but he was even more worried of the weird scissors. He started to back away scared of what the criminal would do to him. “Don’t make this harder for us, we have no time for you. Come here you stupid mutt…” – The taller thug caught Larry by his hoodie and started to cut through his clothes. Larry didn’t understand – Did they want to humiliate him by ruining all of his clothes? Larry gasped as he felt his hoodie and shirt slide off him. He felt even more itchiness as that happened, he looked down at his chest and realised why. “What the… I-Is that f-fur…?!” – He asked the thugs expectantly as he stared at his increasingly furry chest in disbelief. The fur was spreading in all directions making Larry tremble in fear of the unexpected.

The thugs didn’t reply and finished undressing Larry and stripping his of his human clothing which he wouldn’t need anymore. Shoes thrown away, socks pulled off and lastly even his pants. Larry was too scared to fight the two, especially as he felt more changes happening to his body, which was too intimidating to fight. The thugs whispered something to each other while looking at Larry’s underwear, but then one of them waved his hand at that. The shorter thug came over to Larry and crouched in front of him. “Good luck in your new life. Don’t worry, we’ve informed the dogcatcher of your presence, so you’ll have canine company soon enough.” – The thug patted terrified Larry on his head and ran away with the other thug as if nothing happened.

“What the fuck was that supposed to mean…? And w-what’s happening to me…!?” – Larry asked out loud in terror as he realised that most of his body was covered in itchy fur already. He felt weird aches at the end of his digits and so he looked down to examine them. His fingernails slowly blackened and grew out into curved claws to the man’s disbelief. He felt similar discomfort at his feet and he was quickly reassured that his toenails erupted into decently sharp claws as well. “I’m becoming some kind of freak… I shouldn’t have underestimated them… What am I even changing into?!” – He thought to himself in panic which paralysed him continuously.

His transformation absorbed him completely and he wasn’t even able to dress up, since his clothing was entirely ruined. He was thankful they at least they left his underwear in peace. Something started happening in Larry’s field of vision – His nose grew darker until it became completely black. It also seemed to become wider from his perspective, while in reality it was gaining a more canine shape. He felt it get moister and surprisingly sensitive. As if the transformation wasn’t absorbing enough, now Larry was able to smell everything that happened in this alleyway for the past month – That’s how well his smell was in simplified summary.

“My nose… Oh God, it looks so weird, but… Also similar…” – Larry muttered bewildered. As his lips moved they also started to change. Unbeknown to Larry they also became black, but also glossy – Almost gummy in appearance and very iconic for a certain animal family. As if the terror of changing wasn’t enough, Larry was constantly distracted with his improving senses. His ears felt like they were pulled into points by an unseen force. They thinned down, became more flexible in a way and gained a distinctly canine shape. His gums throbbed as they were stretched taut by his growing and sharpening teeth, which gained more carnivorous shapes in his oral cavity. Lastly his eyes blurred, which confused the unfortunate man. His eyesight worsened and a few colours disappeared off the vision’s palette as his eyes became golden brown in colour. “As if changing me into whatever wasn’t a big enough punishment now my sight has worsened…” – Larry thought to himself in a way to try distract himself from worrying.

He thought about yelling for help for a moment, but didn’t have time to decide whether he wanted someone to see him in his current state or not. Instead a new wave of changes centred at his groin and caught him off guard. “Ngh- Not there…! Ah-h…” – Larry groaned shyly as he felt something bizarre happening to his genitals. For a moment of heat down there it felt like his equipment moved lower on his body a bit. Then the more significant changes started. It was too much for Larry, he was forcefully getting horny. His underwear was getting strained with his erection to his utter humiliation – He prayed nobody watched him.

His cock fought the material for a mere while, but then it started to tilt oddly. Larry gasped as his cock started to stiffen and tilt upwards. “Uhn… Why d-does it f-feel goodh…?” – He moaned as something formed inside his cock – A penile bone he was unaware of, which forced his cock into a more feral position. It made his erect cock even stiffer and without the help of his hands it fully extended out of his foreskin which started receding into nothing. Larry sheepishly looked underneath himself and almost fainted as he saw his shifting cock’s tip peek out of his underwear. It didn’t look like his cock – It was redder hue, had webbed veins forming on its slick surface and the tip was sharpening and becoming canine. “Oh Gawd… I’m b-becoming a fuckin’ d-dog?!” – He groaned in lustful voice as his human glans completely lost its shape and became fully canine.

The growing dark brown and black fur tickled the sensitive shaft forcefully tugged tight against the man’s stomach. A warm and tight sensation started enveloping the very base of Larry’s cock. He managed to catch a glimpse of soft flesh forming and folding up at the base – His forming sheath. Soft, dark fur quickly covered the sheath and continued to crawl down onto the man’s ballsack. Larry’s eyes widened as he felt weird swelling sensations in the base of his doggy prick. “Ghn-nh… This issho-weird… Ahhhn!” – His knot slowly formed and inflated because of his massive erection giving his cock a fully canine shape. Larry panted in ecstasy as his bulbous knot slowly slipped past the tight sheath with a wet plop. Larry gasped as he felt his balls clench several times as they started to change and expel the human seed. It was bizarrely arousing to see his own doggy cock spew out the remnants of his human cum onto the alleyway.

Larry whined a bit as his balls finished getting rid of his human cum and started producing virile dog-seed. His ballsack’s hair was replaced by the shaggy fur. His testicles became fully canine at this point and Larry was about to start stroking his shaft, but an ache in his hand caught him off guard. He was still erect, but his excitement slowly faded away as more painful changes started recurring. His silly lust-addled expression became that of worry as he felt his hands become clumsy and the digits shrink and become useless. “Nwooo…!” – He exclaimed, but didn’t continue as he realised how much like a simple dog he sounded already – His vocal chords must have started changing already.

His arms simplified in anatomy, bones became less rotary and more restricted when it came to flexibility. “Ghah…!” – Larry growled as his shoulder blades started elongating and stretching to force his arms into the quadrupedal alignment permanently. Meanwhile his hands gained a paw-like shape and started to grow dark brown fur. His palms became numb and feelingless as they started to puff out and swell into black paw-pads. In a matter of seconds Larry’s hands were completely remolded into a pair of clumsy dog paws. Because of all the unpleasant distractions Larry’s cock diminished in size and slid into its cozy sheath almost completely, leaving only the red tapered tip sticking out and still leaking cum.

Larry freaked out and jumped around, not wanting to accept his new four-legged way of life. He was forced to even harder as his spine started crackling and getting more pronounced on his furry back. His collarbone narrowed to fit his lean dog body. His neck repositioned upwards since he would not go back onto two legs and his body parts had to readapt. His neck started to extend a bit and become more flexible, fur crept over it as well. His vocal chords, didn’t disappear, but repurposed instead into the canine counterparts. Larry whimpered as his increasingly canine head drifted further away from his torso. His lengthening tongue started to loll out of his fanged mouth because of the exhausting transformation.

Larry shut his eyes in pain as his ribs started popping and his ribcage barrelling out. Meanwhile several rows of somewhat sensitive spots formed underneath his original human nipples. Larry thrashed trying to shake off the changes, but it was of no use – They continued nonetheless and wanted to end his remaining human features. His stomach caved in and his intestines churned making the shifting man nauseous as his organs changed to fit his new species. His pelvis cracked and rotated painfully making him whimper again. The skeletal movements caused what was between his buttocks to migrate higher up on his thinning down rear. His buttocks deflated into nothing and became lithe flanks of a dog, in the process shamefully exposing Larry’s butthole until the tail he was about to grow would cover it up along with fur.

Larry’s hips cracked and tightened into a more compact shape. Meanwhile his legs slowly gained their final digitigrade shape. He was forced to stand on the balls of his feet until they started to slowly shift. His already furry and clawed feet cracked and contorted into smaller shapes – Toes shrinking into similar shapes and sizes altogether, underneath them many black pads started to form on the man’s flesh. Shortly after his hind paws finished forming.

A painful tug at Larry’s tailbone brought his attention. He turned his head back and watched as his flesh there started to lengthen, pushed and strained by his lengthening tailbone and newly forming vertebrae. His growing tail wriggled and spasmed as it slowly grew to its final length. In the process it sprouted brown fur just like the rest of his body. His tail finally gained its final length and started to sway nervously behind Larry. “I feel like in a fever dream, more of a nightmare actually. I can’t believe I have a tail – I can almost move it on my own…” – He thought to himself slowly accepting that the changes were unstoppable and he was helpless to stop them at this point.

The changes appreciated the consensus and finished working on Larry’s lower body, slowly travelling back to his head with thrilling heat of transformation. Larry gulped and felt his head start to crunch and change shape completely. Headache encompassed his entire skull as it became more slender and less chunky. Larry growled and despite everything had trouble enduring the painful changes that wrecked his head. His brain was painfully squeezed into a smaller shape – The top of his skull compressed. His head sloped down and gained a wilder shape, that made his ears travel a bit higher on his head.

Larry closed his eyes in fear as he knew what part of his head was left. His jaws tensed up and started to crack and push out. His nose was squeezed to make his face more streamlined. His canine nose along with his mouth pushed out into a muzzle. Larry pawed at it wanting the pain to end already. It felt like the muzzle kept growing for an entire minute in a series of painful growth spurts, but finally it stopped. Larry stared cross eyed at the newly grown protrusion on his face – His doggy muzzle he had to live with from now on. His human hair got replaced by his black and dark brown fur which just finished covering his entire body completely. Last minor changes occurred – New, additional fangs grew out from his wider maw cavity, his tongue lengthened to its full extend and hanged out of his mouth as Larry tried to catch his breath.

Larry had a moment to examine his new body of which everything felt alien to him. He was undeniably canine and probably a dog, though he didn’t know what kind of breed specifically. To himself he looked almost like a german shepherd prototype, but he wasn’t an expert on dogs. Larry sat down on his haunches as he heard some big vehicle getting closer. He knew it was the dogcatcher. Although now that he thought about it. He might have accepted his fate, becoming a dog. But he wasn’t very keen on spending the rest of his days in a dog pound, he still had a chance to dodge the dogcatcher and escape, but he had to think fast…
