It was the start of another amazing day, as goes for all days for toddlers. They wake up, get changed and dressed, and are expected to play all day 'til the sun goes down. So long as they're well behaved (the not-fun part), every day is a good day.
The last month, however, had been different waking up. You see, Murreki has had a guest in his crib; and not just any guest, but his new big brother, Finnian. He grew up in foster care until Murreki's parents adopted him. Finnian could remember the roller coaster ride of emotions he went on that day. Elated and estatic that, of all the cubs there, they chose him. He cried happy tears that day, that of, despite the odd thing that happens to him every night, they wanted him.
He was very scared when the orphanage manager told them about his condition, very worried that he wouldn't then, or ever, be wanted. But that worry quickly turned to pure joy as these fox parents told the manager, "Oh that wont be a problem. Our son will be overjoyed when he finds out."
And their son was. You see, Finnian was born with a very odd and very specific ability. It came at a price, but the husky had no qualms with it. This price was bed-wetting. Of course. The husky boy had lived with this odd ability for 7 years now, and you can imagine how odd it was at birth. Any time a diaper is taped around him, he begins a very rapid and seamless transformation into a plushy. He still maintains full range of motion, speech and cognition, but he now has the appearance and traits of a plushy.
Finnian remembers the first night at his new family's home. It was a long day of memories, between meeting his new baby brother, to having a properly home cooked meal, cooked with love instead of pre-packaged junk that was cheap and just filling enough.
Their parents both knew of Finnian's little secret, but knew it would be fun to surprise Murreki. As night rolled in, Murreki and Finnian were both laid down on the changing table, big enough to fit them both. Murreki got his night-time diaper taped on first, and was told to give Finnian some snuggling support, as it was his first time in a new environment. 
Murreki snuggled in lovingly to his new brother as his parents slowly slid a diaper underneath the husky's bottom. As it was pulled up and taped in place, Murreki saw that his new brother's fur was slowly laying flat and softening greatly. His cold, wet nose drying up and replaced with very soft felt, while the thin fur on his face turned to the softest of silk. Finnian remembered the awe and joy on his brother's face as he saw a plush sit where his new brother once was. It was an adorable sight. Finnian slept very well that night as his baby brother snuggled up to him in their crib. 
Finnian would be getting his own bed and room next week, which he was very grateful for, but he very much enjoyed sleeping in a crib with Murreki.

Fast forward to this morning, a month later. Murreki and Finnian both shared a birthday in the same week, by pure chance, and Murreki had begun entering his frisky-fours stages. Finnian remembered them at the orphanage, and it was difficult to cope, as being naughty with others was very frowned upon. But outside the orphanage, where the norms of growing up properly are not discouraged, Finnian would be able to help his brother through it.
The Frisky-Fours stage of a young mammals life is when they begin going into heat. Anything that they might find pleasurable switch the logical sides of their brains off, and the limbic system is in full throttle, making them instinctually crave pleasure and release until it happens. Sometimes even after climax, its not enough and another is needed, or more!

Finnian woke up first that morning, as the sun shined brightly through their Paw Patrol window curtains. He sat up and pulled the covers off himself and a still snoozing Murreki. Finnian saw that his baby brother leaked throughout the night ... again, and remnance of that still dampened their sheets. However, Finnian's plushie fur easily absorbed it, transferring it to his own soaked diaper. 
Finnian liked it when Murreki leaked, since as a plushie, he never got to experience it himself. He never leaks, because his fur absorbs it. Repositioning himself, he laid in the cool puddle and spooned with his little brother, very slowly moving his tail out of the way and placed a soft paw on the seat of Murreki's diaper. The warmth emanated from it greatly, and he casually pressed upward, causing a great deal of wetness to leak from it and coat his paw, as well as the sheets.
Giggling to himself, he saw the kit's ear flicker and Murreki slowly rolled onto his back, eyes opening to the loving smile of his big brother looking over at him.
"G'morning Finn," The toddler churred through a pink and purple pacifier.
"Hi, soggybutt!" The plushie puppy chirped happily.
"I'm not that soggy, the crib is barely wet!" Murreki retorted.
"It's barely wet, because it all ended up on me and in my diaper," Finnian said with a big grin.
Murreki giggled and kicked the rest of the covers off, looking down at his drenched diaper, thick as ever, causing his legs to spread quite a bit. He eyed Finnian's diaper as well, seeing it swelled up, too.
"F-Finn. Uh-hhmm. It's happening ag-gain" Murreki whined, seeing the thick, dripping diaper on himself and the fully wet diaper on his brother, the kit panted softly as his diaper began tenting up.
Finnian chuckled, "It's alright buddy, I'm gettin' pretty good at this!" The plushie puppy nestled even closer to the fox, his soft and still damp paw gliding teasingly over the front of Murreki's wet diaper, applying pressure to the front as he moved it up and down. Murreki's ears went flat against his head as he panted harder and pressed his waist upward. The silence in the room was done in by the loud, nearly echoing crinkles being caused from the thick diapers. 
Finnian continued, moving his paw between the toddler's legs and giving a soft and gentle squeeze, a finger sliding into the leg gathers for a quick tease and to absorb anything that might try to leak out. Back up the front of Murreki's diaper it went, as he squeezed and rubbed up and down, poking the kit's bits out above the top of the waistband and sped up the pace. Within seconds, Murreki was spraying the front of his body with thick creamy kit-cum, the toddler panting in esctasy as he finished.
Finnian laid beside him, his own diaper tenting up from his silky soft puppy bits pressing against the soft interiour. Murreki laid there in the afterglow, panting and nestling in close to his soft and damp brother. After a few minutes, Finnian saw that Murreki was still in heat, as the kit continued to pant and hump covertly (or so the small fox thought) against his diaper.
"What's wrong, buddy?" Finnian whispered into the toddler's ear.
"I-umm. I'm still -- I nee-" The toddler stuttered.
Finnian picked up Murreki's pacifier and gingerly slid it into the kit's muzzle. "Shh, it's alright." He reassured the little fox.
Finnian lowered his head, multicoloured ears gliding against the toddler's belly, absorbing some cum as they go by and slid his muzzle into Murreki's diaper, taking the whole of Murreki's bits into his maw. The toddler yelped just a tad louder than the crinkling, as Finnian's muzzle burried itself deeper. Murreki would not last long, as the inside of Finnian's maw was softer and wetter than his diaper ever would be.
Less than a minute of the soft silky tongue gliding around the toddler's bits and Finnian was getting his first drink of the day as he gulped down what didnt get instantly absorbed by his tongue, sitting up and staring down at the panting boy beside him. By this point, Finnian was aching for release, his soft, yet firm plushy cock pressing eagerly against his drenched diaper.
"My little brother got one more in him?" Finnian leaned down to lick his brother's muzzle.
Murreki wiggled and smiled brightly feeling the soft and damp tongue glide across his face, enthusiastically nodding, and slowly coming back to his senses from two releases.
Finnian grinned and began untaping his little brother's diaper, pulling it away and, as Murreki prefered, it was then taped around his head, waistband just above his eyes and both ears cutely perked and poking out from either leg hole, his tail flitting all about between his legs.
Finnian looked down at the overjoyed toddler and began untaping his own diaper. It was impossible to do this next part as a plush, due to his absorption capabilities. As the diaper flopped onto the crib mattress, Finnian's plush fur instantly thinned and pulled away from his skin, as if statically charged. His nose returned to the cold damp grit that regular huskies had, and his cock returned to a fleshy texture. He was drenching Murreki's crotch area with pre as he was very eager to continue.
He took his old diaper into his paws, which rapidly turned to plush as he held the diaper, and sat it soggy side down on Murreki's belly. As he let go, his plush paws returned to furry husky paws. Repositioning himself underneath the kit, he slid his way into Murreki's bottom, gasping needily into the air. Propping the little kit's legs in the air on his shoulders, he got into a rhythm and began pumping in and out. He watched Murreki close his eyes and pant loudly, the husky boy doing the same while sliding as far in as he could go, pulling out, and gently pushing deeply back in again. 
Murreki's kitbits were fully stiff yet again, earning a normal, yet very soft husky paw to be wrapped around them and quickly stroking it. Another moment of soft thrusting, panting and some giggles later, both boys were shooting gratuitous amounts of cum. Murreki shot all over the two old diapers, as well as his face, while Finnian flooded Murreki's insides with his brotherly love. 
Ever so slowly, Finnian pulled out and laid down, his real fur becoming damp from laying in the puddle. 
They sat there a while, panting and coming down from the moment. Finnian eventually took both diapers and tossed them to the crib's corner and pulled Murreki into his arms for the softest and warmest snuggles he's ever had.
It would still be a time before their mom came in to wake them up, and until then, they would stay nestled in each other's arms, letting the warmth of love, and eventually piddle, contain them.
