"Where did I put that thing?", inside a flat in the middle of town an average size chap was looking for his blow up mattress that he uses when guests come to stay. A friend of his was coming over to stay for the week, they talked online and really hit off, finding out diffrerent things about each other and finding simiarites they shared, some of which that were quite sexual, the man blushing at the thought of them.
The man who we'll call... Mooky was a fair skinned chubby guy with short, jet black hair on his face and head, his glasses brought out the dark colour in his eyes. Moving a stack of storage boxes he found the mattress "ahh there it is" Mooky let out a sigh of relief as he collected the blowup mattress and put it to one side where he could easily retrive it later.
As Mooky debated on where to put the mattress for his guest to sleep,  a few knocks to his front door brought him out of his thoughts, 'who could that be?' Mooky pondering looking at the clock on the wall it read 4:15, he began to wonder if it was his guest 'no it couldn't be him, hes not getting here until tommorrow morning', another louder bang made him jump out of his skin, without much thought he quickly made his way to his door to open it and found..... a box?.
Mooky scanned the area, there was no one around that he could see, his attention turned to the box picking it up it didn't seem all that heavy, shaking the box gave him no help as to what was in the box. With the box in hand Mooky walked back into his flat and closed the door, little did he know a looming figure hid amongst the shadows watching his every move, chuckling to himself "good he took the gift, now the real fun can begin" he said in a deep gruffy voice.
Now in his bedroom Mooky placed the box onto his bed as he pondered what exactly could be inside, "I havent ordered anything and it's not a special occassion" rubbing his hand through his beard, "he must of sent this" coming to that conculsion, he grabbed a knife and sliced through the tape. Shock  was the only expression that he could make as he pulled out a soft crinkly undergarment. A diaper and not just any regular old diaper, one that he had never seen before, it seems to be made of a strechy yet soft material making it a one size fits all or maybe even a diaper that can hold a lot before needing to be replaced, the soft insides look to be very absorbent and felt like a cloud when Mooky place his hand on it, looking at the designs on the front of the diaper he saw two anthro animals on the front both wearing diapers, one was a animal he knew all to well, it was his fursona an European otter with the same name as his, though it may have been a small picture he could see that every little detail was there from his eye colour down to his fur markings it was all there, the other figure however he had never seen before, it was a british bulldog that had a muscle chubs build with red hair on top of his head, the dog had the fur pattern of a rottweiller, he also had some tattos of famous nintendo symbols.
Oddly there was a hole on the back end of the diaper, 'strange' he thought, 'why is that even there?, its not like I have a tail' chuckling to himself, he ponder how cool it would be to have a tail. He Started to toy with the daiper in his hands the need to try one on rising inside him, like the diaper was calling to him. It wasn't long before he gave in, laid out the diaper on the bed and removed his clothing, before moving onto the bed he took a moment look at himself in the mirror. The years hadn't been that bad for him, sure he was a bit chubby but people said it looked good on him, he ran his hand across his furry mid section down to his package, he grabbed a hold of his below average size cock, pumping it slowly as he thought of the things he could do in his new daipers, shaking the thoughts out of his head he sat down on the laid out diaper, the softness overtaking him, it was the most comfortable thing that he had ever sat on. Letting himself sink down a little he laid down and fasten the tapes, he was finished, it was so relaxing he could almost just let go and..........
A slight pang in his backside jotted him back into his senses, "ugh how long have I been out?", he looked over at his digital clock on his bedside table to see that only 5 minutes have passed, with a sigh of relief he got up only to notice a warm soggy feeling on his front. He couldnt help but blush as he realised that he had wet himself. He let out a nervously laugh "heh it's a good thing I put one of these on, that could have been a disaster", his cock was standing on end from all of the soggyness, A soft moan escaped his lips as he press his hand into the front of his diaper, " I guess I should enjoy this before I change" letting his sexual arousal take over, he failed to notice the changes that were taking place.
A small nub was starting to push out of his tail bone, conveniently slotting through the hole on the back of his diaper, his body hair started to grow thicker and turn into fur, some patches of his fur were different colours on his body, his back fur darkening a little but staying black, the fur on his arms and legs brightening up a bit and turning a brown colour, his front fur changing the most, turning a very pale brown, keeping his eyes closed his hand explored the fur covered parts of himself, his hands were the next thing to changed, the digits shrinking a bit and puffing out, the skin on the inside of his of his fingers and thumbs fusing and thining out turning into webbing, the plam of his paw and tips of his digits growing extra skin which puffs out and solidifies, become squigy paw pads, the fur was spreading down his arm and onto his paws as his nails became sharper turing into small claws. Bit by bit his tail was growing longer and thicker, the fur following it up until the tip, Mooky was losing height and fast as his arms and legs shrank to the same height, making it easier for Mooky to move on all fours. Flattening and pushing out wards, his feet looking less human-like as his smallest toes on each foot paw merged together and swelled up like all of his other foot paw digits. His under belly covered entirely in fur as his private parts followed suit with the transformation, his balls growing a little larger as they were covered in fur, mookys foreskin pulling back as it grew thicker at the base of his cock and sprouted fur forming a sheath, the cock now swelling out a little as the head started to taper out into a pointy head becoming a canine shaft. Lost in his own world mooky was happily chriping and squealing away as the final changes took place, the fur spreading up his neck as it thickened and shrunk slightly, the skull structure of Mookys head shifted as his ear shurnk down and rounded out as they moved behind his head and rised up a bit, the fur covered his entire head adding a bit more fur to the top of Mooky’s head to act as hair, with one final change mookys jaw pushed out into a muzzel with his nose darkening and turning rubbery.
The changes had finished, what once was a average size stocky human was now a 4ft 6, diaper wearing otter still exporing his new body unknowing that someone was watching from the shadows and moving closer to the newly turned otter. Mooky felt a chill down his spine as he felt a paw on his shoulder, in a gruff voice the mysterious figure spoke, "Enjoying my present, my pet". Turning on a dime, mooky spurted out "woah, hold on...... a......... sec?" as he looked up at the figure in question his eyes widened in astonishment, the bulldog on his diaper, it was him, he was so big, he he was wearing a diaper, the exactly same one he was wearing only unsoiled. "H-How di...." stopping himself in mid sentence he noticed that his voice had change it was higher than before. Turning to the mirror the reflection filling him with fear and a little excitement, his fursona was staring right back at him in the mirror, panic rose in him as he frantically moved his paws up and down his new body, discovering a new sensitive spot on him, with one paw playing with his tail he pressed the other one to the mirror, "what happened to me?".
Bending down to Mooky’s level the bulldog answered "you bacame you Mooky, who you really are"
"This isnt me I’m a human”
"Not anymore my pet, beside humans suck. Our animal forms are so much better and sexier"
"Says who? And stop calling me that"
 "Come on you're telling me that you’re not the least bit happy with this? I see that cute tail of yours wagging"
Blushing at the comment made on his tail Mooky changed the subject " how did you even get in here anyway? Who the hell are you?"
"Hehe I have my ways of getting into places", chuckling to himself the bulldog continued, "as to why I'm here, I'm here to be your master for the night"
"M-My master???", the thought of that made Mooky a little anixous but also filled him with excitement, having a good look at this bulldog, he couldnt help but notice how well bulit this guy was, his arm built like two huge iron bars, he was barrel chested with a cute chubby muscle gut, looking further down to his legs that were like two huge tree trunks, his eyes became fixated on his diaper, he couldnt help but wonder what was inside the diaper, his mind pondered the many different shapes and sizes of canine cock. Shaking the thoughts out of his head, mooky tired to keep a blank face in front of his mas- this bulldog not trying to show his excitement, his tail betraying him.
The bulldog smirking a mookys struggle to hide his excitement, he started "aww are the master’s words exciting my little pet"
Feeling his arosual rising up again he stuttred "S-shut up, they are not"
"Heh oh really?", moving closer to mooky his diapered crotch now hovering a few centermeters away from mookys face "this isn't turning you on just a liitle bit?"
Smelling his masters scent mooky became briefly intoxicated by it, pressing a paw into his masters diaper he felt his shaft, letting out a happy sqeaul as he did, Coming back to his senses, Mooky pushed the bulldog away "I told you I'm not your pet, your play thing you can just use, I'm not even into your weird stuff anyway"
"I've seen your FA page Mooks, I know exactly what you’re into" the bulldog claimed, winking at Mooky with a smirk plastered on his face.
That caught Mooky off guard, unsure of how to respond Mooky looked away from the bulldog, rubbing his arm with his other paw "what are you going to do with me?" mooky asked, scared of what the answer might be.
"Nothing that you won’t enjoy my friend" Mooky’s ears perked up on that last word, turning his head to see the bulldog holding a collar in his paw, the collar was a bright red colour with a silver diamond shape tag with the name ‘Mooky’ inscribed on it "where did you even pull that out of?"
"Not important, look I'm just here to give you a fun night of being a pet, something that you've always wanted to do with someone right?"
Not recieveing an answer from the otter the bulldog held the collar in front of Mooky "it's your choice, you reject the offer, I'll be gone, never to bother you again, but if you accept my offer I can show you how fun having a master can be for the night" He place the collar in Mooky’s paws and retreated back a few steps.
Running his paws around it, Mooky pondered 'it's something I've always wanted, but how can I trusted this guy, I dont anything about him, he hasn't done anything to harm me, he had many chances to, but for all I know he could swallow me whole if he wanted to’. Gulping at the thought he made his decsion, taking a big breath in and then out he answered "okay.... okay I'll do it but as long as you promise me that you wont swallow me whole"
A huge fit of laughter erupted from the bulldog "of course my pet I promise", rolling his eyes at his pets ridiculous request.
Uncliping the collar Mooky put on the collar, he prepared from some sort of magic to take him over making him a mindless pet, ready for masters bidding. He waited patiently to feel..... nothing?, no magic, no haze, no mind control, NOTHING???
"Hey what gives I thought this collar was gonna make me your pet?"
"Ahh but it has my pet, by putting on the collar you have offically become my pet and I, your master for the night, besides it's not like I had to convince you to like being my pet, you already do" Master said, scratching behind Mookys ear, sending a odd sensation of relaxation through his body.
"Now I think we should get that soggy diaper off of you" master patted the bed "come on Mooks. Up", Mooky did as his master said, quickly jumping up onto the bed and laying on his back. Removing Mooky’s diaper, master couldnt help but notice the package, “ 6”  inches hard, aye Mooks. That's impresive for an otter" master sounding quite surprised at the size, pulling down his diaper revealing his own canine shaft which was 7 inches hard, comparing sizes of both cock master produly exclaimed "almost as big as your own master".
"I....small.......ones"
"Hmm whats that Mooks?"
"I hate my big cock, I wish it was smaller" blushing as he explained, not making eye contact with his master.
A mischievous smirk appear on masters face, "well I think I can help you out there my pet" grabbing both cocks in his paw master started to pump them together. The sensations mooky felt were almost alien, like some sort of weird energy was flowing through his shaft, he watched in amazement as it appeared that his masters shaft was growing and his shrinking, as the pumping continued the energy only intensifying, bringing more pleasure onto both of the beasts, 6 inches became five as mooky was losing himself in the heaven he was experincing.
"You like that my pet?" master said starting to hump his pets shaft as he pumped.
Chriping away mooky was lost for words, it was hard to think as his cock shrink down to 4 inches, looking at his masters shaft it was over double the size of his, drawfing his tiny shaft.
Chuclking at his pets expression he started to tease him, "liking what you see mooks, to see that your pecker is becoming smaller and smaller, to see what once was an impressive tool, demished to a laughable, adorable shaft" teased master.
Feeling hot around the face, Mooky couldn’t take his eye off the ever changing shafts, "P-p-please", Mooky whimpered out.
"Hmm?, does my pet need realease?"
"I'm close master", his shaft now down to 3 inches "let me shoot"
In a calm, deep voice master answer with only one word "cum"
"AAAAHHHH" ropes of cum shooting out of Mookys now below average size cock, making a mess of himself, grabbing a towel, master cleaned all of the cum that was in his pet’s fur. After getting Mooks all cleaned up, master disposed of the dirty diaper and replace it with a brand new one. With a yawn mooky felt like he was ready to settle down for the night, letting tiredness overtake him, he was drifting off.
Click
That sound bringing him back up, looking down at his collar he noticed a clip was now attached to it, following the thick line of rubber to a hoop of the same material attached to it, finding his master holding the other end.
"Okay, where did you get that from?!?!"
"You know, you ask to many questions my pet, now come on" master said, softly pulling on the lead, gesturing for his pet to follow him
"But I'm tired master, do we have to?", Mooky pleaded as he lazily moved onto his belly
"Yes we have to. Now come on, its a nice night out, lets go for a walk"
"A walk??, Y-You mean o-o-outside??? We cant do that we’re not humans, I will be burned at the stake!”
“Its dark out plus no one will probably be around at this time of night, you’re my pet remember?, they would only see a cute little otter being walked by it’s owner"
"That’s probably still a little weird though"
Pulling on the leash, and making Mooky fall off the bed, master seemingly a little annoyed by the conversation spoke "just come on Mooky you'll enjoy it, trust me", flashing a toothy grin back at mooky. Seeing how sharp and pointy masters teeth were intimidated him. With an involuntery gulp he followed his master out of his appartment into the cool breeze of the outside world.
It was nice out here, peaceful with not a soul in sight, Mooky hear the crunch of the grass below his paws, finding it easier to walk on all fours instead of on two like his master was. Seeing that they were alone, Mooky took the chance to ask master some things that had been on his mind from the begining.
“Will I be like this forever?”
"You’ll turn back, don’t worry. Tonight you are my pet, tomorrow who knows, it's up to you"
"Why me? Why not some other diaper loving furry on the internet?? What makes me so special???"
"I choose you to be my pet because you wanted it, sure I could have found some other furry, controled him against his will and made him my pet, but I knew that if I ask you to be my pet you wouldn't refuse, I mean think about it, you took the package, put on the diapers and instead of tring to stop the transformation you got lost in it, just like you let me take half of you shaft’s lenght without much resistance. Lastly but certainly not least I gave you the collar and you put it on without much thought, do you want to know why?"
"Why?"
Master kneeled down and continued “it’s because in there” he pointed to Mookys chest "you wanted to be a pet to someone, just like in here", this time master pointed to his chest "I wanted a pet just like you"
The two not sure what to say after that little moment they just shared, mooky feeling touched by his master’s little speech. Master got back up, putting one paw to his neck, rubbing it "heh sorry that got probably a little too senimental there, we should probably get back"
Just as they were about to turn around and head back, they almost simultaneously had the urge to realease their bladders, they look at each other, both nodding as if they knew what the other was thinking, almost as if a signal was given they both started to let the flow into their pants so to speak, the front of their diapers turning a shade of yellow as the absorbent material did its work, finishing up their business, their own arousals started to peak as they began to explore each others soggy diapers, pressing their paws into each others diapers earning a moan for mooky and a growl for the master.
"Mooks lay on your back I have an idea"
Obeying his masters command, mooky laid back on the grass as his master crawled on top of him so that their diapered fronts were almost touching, master leaned into mooky and whispered into his ear  "you'll enjoy this my pet", planting a few kisses on Mookys muzzle, master started to rub their daipered fronts together, earning heartly moans from both of them.
“M-master this feels amazmphhth"
"Sorry mooky but we have to be quiet just in case there is someone around” he said, covering Mooky’s mouth with his paw, master continued to hump Mooky’s diaper. Planting kisses on just about any place master could get to. He wrapped his free arm around mooky hugging him tightly. Mooky was in heaven, letting happy chrips and squeals slip out of the sides of his mouth, he wraps both his arms around masters neck, starting to hump in rhythm with his masters humps.
"That's it mooky now youre getting it", Mooky’s efforts earning growls and more kisses from his master as both him and Mooky were getting close. "Master I dont think I can last much longer"
“Me too mooky. Cum for me”
“M-MAAAAAHHHH” Mooky moaned shooting spurt after sprut of cum into his daiper.
“ARRROOOOOOO” master howled as hes a shoot a load into his own diaper.
Both took a moment to catch their breath before getting back up and heading back to Mookys apartment. Master drew a bath for mooky to wash all of the cum out of his fur, Master’s paws now firmly washing Mooky’s fur, the petting of his fur sending waves of relaxation through him as he bagan to sink back into the tub. After Mooky was all nice and clean, he gave a towel to him and let him dry himself off, after that was done master re-diapered Mooky and put him to bed.
"So how was it being my pet for the night?"
"It was amazing master, can we do it again sometime, please?" Mooky looking up at him with big puppy dog (errr otter) eyes.
"Haha you never know Mooky, we may meet again", master said with a wink and with that he turned and began to make his leave.
“Wait! I dont even knopw your name”
"For now just call me master, see you around my friend" and with that he was gone.
'That was awesome' he thought 'I wish he stuck around for one more day'.
Mooky pondered on exactly what could have happened when tiredness took over him, it wasnt long before he drifted of to sleep.

BEEP BEEP BEEP
Mooky jolted up and looked over at his clock.
It read 8:30, 'looks like I had a good nights rest' he thought, it only occured to Mooky on exactly where he was, instead of being tucked up in bed like he was when master left, he was at the end of the bed like he was when... "wait, wasnt I here when I tried on the.."
Rushing to get up Mooky looked in the mirror to see that he was a human in a wet diaper, putting his hands down into his diaper, he found that his package was his normal, average package.
"Was it all a dream?", he quizzed as he looked in the mirror, feeling the cold dampness of his front, Mooky decided that he should probably take a shower. Through out the day Mooky could not shake the thought out of his head, "it must have been a dream, yeah, yeah thats what it was, I mean me turning into an otter with a bulldog master haha, I must stop having a drink before I go to bed’.
Hearing a knock at the door Mooky’s mood brighten as he realised who was at the door, " ahh hes here right on time" making his was to the door and opening it to his friend.
"Hey Adam its great to see you"
"Likewise Mooky how have you been?", Adam said with a glad expression on his face happy to finally meet up with his buddy. The man standing in the door way was at average height, with a stocky body, he was quite a hairy bloke with a dark beard and hair.
"I've been great Adz, how was it getting up here?"
Puting his bags onto the floor as he made his way into Mookys living room Adam stretched then answered Mookys question, "Meh it was alright, the usual traffic and what not"
As Mooky helped Adam settle in to his home, it dawned on him that maybe Adam could have been the one who had sent the gift, "Hey thanks for the present by the way"
"Present?"
"Yeah you know the package you sent, it arrived yesterday"
"I'm sorry Mooky but I dont know what you're talking about, but oooo whats was in it?", adz replied,  his speech turning from quizical to curious.
"Hehe curious huh?, wait here I'll go get them, this weekend is gonna be so much fun with them, ohh and I've got to tell you about this dream I had last night, it might make a good story for our collaboration story"
"Cool Mooky can't wait", Adz sais, watching as Mooky excitedly ran off into the other room, as Mooky was fully out of sight, Adam let out a small chuckle to himself as he pulled a red collar out of his pocket.
"Oh yes this weekend will be the best, my pet"
