Sitting at his desktop insdie his average looking flat sits a bored looking twenty something year browsing various sites on the internet, nothing in particular just going from site to site hoping to find something that fits his fancy.
His name was Adam, a pale skinned nerdy lad who was into a couple of weird things but would never mention any of them. He was a chubby guy with a bit of muscle that had been built up over the years of weight lifting. He had a scruffy look to him with a rugged beard and messy short hair, looking at the time in the bottom right of his computer screen before shutting it down, realizing it was almost one in the morning he leaned back into his chair, rubbing his cinnamon brown eyes he let out a sigh.  "Well another day wasted surfing the net finding bugger all" said Adam running his hands through his jet black hair on his head.
He was thinking of going to bed and getting some sleep when he heard multiple loud and hard bangs on his door that made Adam jump and fall out of his chair. Shaking a little from the shock he got up and made his way out of the room into the hallway, 'strange' he thought as he made his way to the door 'I wasn't expecting anyone to come visit especially at this hour'. As he put a hand to his neck scratching it sightly, pondering just who could be at his door at this time of night Adam then realized stopping in his track as he question "wait how did someone even get in?, wouldn't have i had to have buzzed them in?". spending only a short amount of time on that thought he quickly came to the conculsion that the door must have been left open again, making a mental note to check if was opened or not later he finally got to the door hoping that the mystery figure at his door hadn't left or worse was pissed off at him for taking his time answering the door.
Taking a deep breath as he unlocked his door, turning the handle and swing it open to find..... no one?. Looking around the empty hallway finding nothing but the way too bright sludge green painted slightly worn walls staring back at him and making his eyes hurt. "Jeez they really need to re-paint those walls to someting less painful to look at" Flinching as he spoke. He sighed as he came to the conculsion that he must missed whoever it was at his door, mentally kicking himself and making another mental note to text the few friends he had to ask them if it was one of them who knocked on his door when he gets up in the morning. Turning around to re-enter his home. out of the corner of his eyes he spotted something on the floor next to his door, it was a box, the box was pretty big but it wasn't to heavy and was completely blank except a small postage sticker that had his name and address stuck to it in the upper left hand corner on top of the box.
Without any hestitaion Adam quickly picked up the box and made his way to the bedroom, shutting and locking his front door behind him. Placing the box on his bed, Adam began wonder just what was inside this box, "what could this be?, I haven't ordered anything in a while have i?" he whispered to himself. Grabbing his pocket knife form his bedside cabinet he cut through the tape, what was inside the box gave him a mixture of emotions. His hands started to shake as he pulled out a head of a fursuit, specifically one that looked like his own british bulldog fursona, atleast how he imagined it. Dumbfounded he quickly pulled out the rest of the fursuit, it was amazing just how similar this suit was to his own picture of his fursona he had in his mind. it was perfect from the the colours of the fur (black and brown) and the layout of the fur to the tatoos of various videos game icons he wanted to get but never built up the courage to get them. Sitting on the edge of the bed with his head resting in his hands Adam could'nt believe what was happening "but how?, no one knows that Im a furry let alone what my fursona looks like down to the littlest details" Adam ponder as he looks back into the box hoping to find an answer to questions that are whirling around in his head.
There were two more items in the box, the first was a collar and the second was a folder up piece of paper. Adam seemed drawn to the collar , it a crimson red collar that had bronze spikes all around sides of the collar, attached to the collar was shuriken shaped dog tag that had his name inscribed on it, a weird thing he notice was that instead of a buckle keeping the collar attached it had a clip keeping it attached. Reaching out and taking it into his hands, the feeling of the leather and bronze spikes making him feel certain urges that felt odd but at the same time familiar to him, pushing those ugers down he put the collar down back into the box and picking up the note, unfolding it Adam read note his cheeksburning as he did.
'A gift for my pup'
'My pup' those words repeating again and again in the back of his my filling him with a sense of shame and embarrassment, but at the same time filling him with a sense of pride, excitement and arousal, coming back to his sense he notice the tent that was begining to rise  in his shorts, walking back to the bed he picked up the fursuit, debating on wether to try it on now or wait until after he comes home from work tomorrow, "who am I kidding, I wanna try it on now" sounding like a kid who had found his christmas present early.
Stripping out of his shorts and t-shirt, he was now standing in front of his full length mirror he could now see his body in full. Looking over his body, wishing that he had a bit more muscle to his fat muscle ratio. Picking up the fursuit running his hand along the soft material that was used to make this suit, "whoever made this must have some amazing resources, it feels just like real dog fur" he said with a smirk on his face, the excitement building up inside his. With trembling hands, he put his legs inside the legs hole, one after the other. As his feet reach the footpaws he couldn't help but notice that the suit felt snug but also so comfortalbe at the same time, like he was putting on his own skin. Adam blushed when he moved the suit up, this suit had a special enhancement for his parts, after a liitle rummaging around he managed to slot his cock and balls into right places, he frowned a bit seeing that his dick was dwarfed a bit due to the stealth covering a fraction up his junk. Brushing it off, he put his focus back onto put on his fursuit, slotting his arms through the arms of the suit, flexing the paws of suit, still astonished by this strange but also amazing feeling this suit gave him, zipping it up, the deed was done.... well almost he still had the head to put on. He took time examing the head as he picked it up, it was shaped like a British bulldog, from the rounded ears down to the floppy cheeks on the side of its muzzle. The eyes were a ruby red, as were the tuffs of hair on top of its head, Adam poked the teeth sticking out on the sides of the muzzle "damn why are they so sharp"
'thats because there real'
Jumping at the strange voice, Adam quickly spun round his eyes scanning the room he whisper "is someone there?", there was no response. "M-maybe it was just my imagination" he stuttered, after a few moments he let out a sigh "yeah that's it im just tired it is almost 2 in the morning after all, I better quickly put this and then go to bed". His Paws trembled as he slowly place the head over his own head, the visabilty wasn't all that great but he could still make out his own relection in the mirror. As he saw himself in the fursuit only one thought appaered in his head 'this feels right', feeling giddyness wash over him he let out a few barks and arfs, chuckling to himself as he did. Although this experience was amazing he couldn't shake this nagging feeling in the back of his head that it was missing something. His attention was turn to the collar on the edge of the bed a sudden force almost drawing him to it, making him need to wear it. As he picked up the collar, running his paw along the bronze spikes the strange voice returned to convince him further to put it on.
'This is what you wanted, right?, you said yourself this is right'
'Go on put it on it will help you become who you truly are and who you are meant to be'
The voice sounded like it was making more and more sense with each sentence it spoke, 'but what does it mean when it says I will become my true self?', this thought making him a little concerned, but the more he laid eyes on the collar the more his worries seemed to disappear. A moment he decided to throw all caution to the wind and made his way back to the mirror. moving the collar up to his neck, a waves of nervousness and excitement washed over him, wrapping it around his neck and connecting the clips it was finally on, he flicked the tag, the jingling noise it made sounding soothing to him. Looking down he notice that he was still hard, "heh, maybe I should take care of this, then I can take this suit off", he said grabbing his cock with his paws, loving the sensations it was giving him, little did he know that he wouldn't be taking off this suit ever agian, his fate being sealed as soon as he put on the collar.
Falling on to the bed Adam made himself, making note not to lie on the tail, as he began to explore his body with his paws the magic of the fursuit began to take its effect. The insides of the suit began to meld with Adams skin, his body hair growing thicker  and blending in with the fur that was becoming his own, his hands and feet changing shape becoming more rounded with his fingers and toes puffing out and shrinking down with the four toes and fingers on each hand and foot merging together,the pads on the inside of the paws slightly puffing out to complete that section of the of transformation. the feelings were now mulitplied, he felt a strange need the need to be pet, his own rubbing not satisfiying him the way another person could, he felt slight tang of pain down his lower back area, as his tail was attaching itself to the changing human, it started to slowly wag as it came to life. Growls and moans escaping his mouth as he put one paw behind his head when began to realies something, the zipper it was gone, he immeditely threw both paws and frantically search his back hoping to find the zipper, fear began to rise inside when he realised that the zipper was gone and he was stuck in this suit, probably forever. His already rock hard cock was starting to grow large, leaving the skin around the cock to merge with the stealth, the cock was turning a crimson red and  becoming pointed at the tip of it, the base of the penis started to bulge out becoming the knot of the doggie dick. Adam reached out and scracth along his dick, impressed on how durable it was, "Am I becoming a anthro dog?", his now more deeper, scruffier voice startling him a bit, then he began to realise he was becoming an anthro dog, something that is only fiction, a shiver went down his spine into his tail which was now curled into his legs ' what am I gonna do!!!???' he started to panic 'how am I gonna go outside without anyone noticing, what if they think Im a monster, a freak, they'll probably do weird experiments on me, they might hunt me down and kill me, what about my family, my friends, i can't face them like this' painc was rising in him as more and more thought ran though his head until the strange voice intervened.
'Isnt this what you wanted?, to be who you feel you are on the inside?'
Adam paused to ponder on what it just said, 'but how?, how can I live a normal life like this?'
'Just let go, giving into who you really are, i promise you that everything will be okay, just becoming the pup you are'
"You're right I am a pup", he said as he grabbed his doggie shaft, "I accept these changes, I want to become this", as soon as Adam mentally accepted his fate, the changes started up again and speard faster around his body, his muscles grew stonger as his arms and legs got bigger, his belly change too adding more muscle to his abs but keeping his pudge intact, giving him a more muscle chub look, his puffed out and became rock solid, "YYYEESSSS MMMOORRRRRGGRRRRRR!!!" he was slowly losing himself in the transformation, moans turning into growls and barks as the changes spread up to his head. The structure of his skull began to change, his ear moving to the top his as they were bending and flattening out to become his new dog ears, his eyes started to change colour from the boring brown eyes to his ruby red one for the first time the suits eyes blinked he could see perfectly, everything around him look so much clearer than before especially his new form, his cheeks strecthed out and grew more flabby just like a real bulldogs would be, "CHANGRRRRRRR ME MORRRRRRRRRRRRRRRAAAAAAFFF!" it was harder to speak as the growls were taking over. Finally his jaw line started to push out and elongated, as his teeth were becoming sharper with two of the pushing out of the growing muzzle, the mouth of the suit was now able to freely open releasing more braks and growls along with it, Adams nose flatten out and darken becoming a little damp, his sense of smell was heighten he could smell so many more scents that a humans nose could not, though the one scent he was focused on right now was his own arousal.
Getting closer to his limit, the voice started to talk again 'this is now your true form pup, the longer you stay in this form the more desire you will have to stay as a pup' the words being planted into his brain, rewritting his memories, he was always like this he only used his human form because people would fear his true form, outcast him 'you own arousal will change, a lot more kinks that once turned you off will now be the only thing that turns you on as well as the other kinks you're to shy to admit' his mental structure being changes weird kinks that disgusted him now were on his mind edging him closer 'cum for me pup when you do all of this will be cement into you forever', he was getting close, a liitle tang in his head telling him to stop growing quieter and quieter.
"GRRRRR THIS IS ME, I AM PUP AAAAARROOOOOOOOOO"  with one final pump he started shooting, spurt after spurt of cum landing on his fur, as Adam was coming down form his orgasm he scooped up all of the cum that he could out of his fur and off of the bed, licking it out of his paws, with one final yawn he turned to his side and drifted off to sleep. Who or what was that strange voice?, did it send me this package? and more importantly how do i change into my human form?, all of these question were floating around in this canines head but for now Adam was too tired to care.
