Nishi brought Yosh up to the front of the class for a special announcement, “Today Yosh and I will be showing what we learned over the weekend. But we’ll need a volunteer!”
Yosh blushed, thankful he wasn’t the one demonstrating in front of the class, but knowing what was inside the box he was holding, part of him wanted to be. 
“How about... you! The flamingo girl.” Nishi pointed out. 
“I have a name...” she whined as she headed up to the front. 
“You sure do, today you’re Diaper Flamingo! And Yosh and I are your dads.” Nishi nodded. 
Yosh smiled a little embarrassed, but also surprised Nishi didn’t say Yosh was the Mom. 
“Or Yosh is your mom.” Nishi cut in. There it was. “Either way, today we’ll be demonstrating how to diaper up the classroom!”
Yosh’s white cheeks turned hot pink. 
“So, first let’s lift up that dress...” Nishi announced as he lifted it. 
“Hey!” Blushed the flamingo. She had on a white pair of panties, as the whole class could now see. But not for long. Nishi pulled those down and everyone gasped! But they couldn’t see too much behind all her pink birdy feathers. Yosh was nearby and couldn’t help but look a bit. 
“Alright, changing table!” Nishi picked up the light bird and sat her on a big table in front of the class, giving everyone a profile view while she sat directly facing Yosh. Nishi laid her down quickly, Yosh’s eyes lighting up as her cute little feathery vulva was nestled between her long white legs. He wasn’t supposed to be seeing naked girls in school!
“Diaper Time Yosh!” Nishi announced. “He’s an expert at this.”
Yosh dug through the box and found a pair of diapers with little pink hearts on it. He quickly lifted her bottom up, both of them a bit embarrassed with his hand on her rump, slipping the diaper under, and quickly taping her up. 
“Don’t forget the powder, Yosh! Don’t be shy, show them what we learned.” Nishi laughed. 
Yosh and the flamingo both blushed as he untaped her diaper, pulling it outward, and seeing her cute little birdy lips again. He felt so surprised to see her cute naked privates right in front of him! But he grabbed the powder and sprinkled it lightly over her front. He noticed her twitch a bit shyly, and breathe louder as he did, but before long he taped her padding again and looked away, red in the face. 
“There we go! Let’s see!” Nishi smiled as he pulled her off the table and lifted her dress, showing everyone her new outfit. 
Yosh blushed seeing all the hearts on her diapered butt. He might have liked that more than seeing her front! Nishi dropped the dress, which was now hefted up a bit by the large cloth underneath it. 
“Alright so who’s next?” Nishi asked. Yosh gasped! More?
Yosh’s friend pulled up a happy looking pup up to the front of the class. He grabbed on his blue jean shorts and tugged them down! The boy yipped and looked down embarrassed, as everyone saw his blue and white briefs wrapped tight on his body. Oxnard I mean Nishi then turned him around and tugged those down too, showing off his little brown furry buns. Nishi gave him a spank to let his butt jiggle for the class, and Yosh from the very front saw the poor puppy’s front jiggle just as much! Would he be diapering up a boy classmate next? 
“Be a good boy and go to Yosh!” Nishi smiled, the shy doggy covering between his legs, trying to jump and sit on the table while covering himself for Yosh. 
Yosh looked through all the diaper designs and found a cute one with blue puppy paw prints all over the front. They seemed like the type to disappear once wet. 
Yosh once again grabbed the boy’s butt to lift him up, which made the pup laugh, and then the rest of his classmates laughed too. 
“Hey, Yosh quit playing grab ah-" Nishi stopped himself before cursing in class. “Uh just diaper him.” 
Yosh nodded, but his paws covered his privates. “Um, please move your paws Charlie.” But the boy was embarrassed. 
“Babies are like that Yosh, you gotta step in!” Nishi advised his buddy. 
Yosh grabbed his puppy paws and lifted them up, spotting a small puppy package between his legs. 
“Winky surprise!” Nishi cheered, as Yosh blushed and tried powdering him politely. “Don’t worry buddy, Yosh has cute little bits too!”
The classroom giggled as Yosh blushed. “Hey!” He went ahead and taped up the diaper and pat the front, enjoyed the cute diapers he got to help with today. 
The puppy hopped off and a bunch of powder floofed from his body as he landed. Yosh notes to go lighter on the powder maybe!
Nishi continued stripping students one by one. From cats to birds, dinosaurs and ducks, each little one lost their pants and undies in class and waddled up to Yosh. He saw so many types of bits! But over the cat girl’s fluffy white pussy, he gave her a cute lavender diaper. The sweet birdy in class has light blue feathers, and got a little white diaper with blue diamonds in front. A chubby dinosaur boy in front of Yosh had a big belly, and some regular average soft boy parts, Yosh just had to work a jungle themed diaper around his thick tail! Derek the boy ducky had a very shy peeper, Yosh powdered it and it hid more in his feathers! Yosh gave him a fun pair of diapers with party balloons on the front. Derek rubbed the padding curious but happy! 
A little cow girl had some udders down below, Yosh had to try and fit them all in her diaper, but after much struggle he just made sure they covered her privates and let her udder swing free on top. 
One little yellow yoshi girl was very antsy. She kept squirming her legs together after being stripped of her bottoms. Yosh smiles and watches her tail, but recognized the potty dance easily. Nishi must have too since he tickled her before sending her to Yosh. 
“Ah...” Penelope whined as she sat on the changing table, already tense from her potty troubles, but more so knowing the cute half-yoshi in class could see her smooth white and chubby little yoshi parts! Yosh had been blushing all day seeing his fellow classmates in diapers, and undressed in front of him too. 
“It’s okay...” Yosh tried to calm the girl down, trying to pet her belly soothingly. 
“Oh no!” She closed her legs tight and blushed. Yosh decided to make it quick, hooking the diaper around her tail, and moving her legs apart, but as soon as her shy yoshi tweety appeared, she started to tinkle and gasp. Making shy whimpers as Yosh watched the girl pee right in front of him. He quickly pressed the diaper against her privates, feeling them soak up her pee, quite warm and hot. He held it in place as she sighed, eventually finishing. She and Yosh made shy eye contact for a moment. He then removed the diaper and politely got a cloth to clean her up, brushing it along her little white lips, before sprinkling baby powder on her and taping her diaper. 
“All better!” Yosh tried to make her feel like it was no big deal, but her classmates giggled a bit knowing something must have happened!
A few more diaperings went by easy. One of the rabbits in class was a little tough since he got a lil boner during the changing. Yosh looked at Nishi for help, giving the class quite a view as his penis poked straight up. Everyone’s laughter made him blush and shrink down. Yoshi quickly wrapped it up and all was well!
“Just one more to go!” Nishi looked at Yosh. 
“You?” Yosh guessed. 
“No, you!” Nishi chuckled and yoinked Yosh’s pants down. He had quite a tent in his briefs. Nishi tugged then down too, letting Yosh’s small boner bounce around in class. Everyone chuckled, despite them being exposed earlier as well. Nishi sat Yosh on the table, spread his legs, removed his shoes and shirt, leaving him naked except for his socks. 
“Awww how cute.” Nishi pat Yosh’s cheek, tying a baby bonnet on his head. Yosh felt quite bashful about that but it was soon followed up by a pacifier in his mouth, and a bib around his neck. 
“Mmff! Miffy!” Yosh moaned through the muffling pacifier. He never thought he’d get such a baby treatment after diapering everyone. 
“Oh yeah uh what else.” Nishi thought out loud before sprinkling Yosh’s balls and penis in baby powder, rubbing and squeezing them in his paw. Yosh muffled a whine, rotating his hips and thrusting, either to get away or out of sexual instinct. But it didn’t work well and before long Yosh felt a climax hit, in the middle of class! He quacked loudly and shivered as his little winky throbbed, but it couldn’t produce anything. It just stiffened needingly during a few spasms before tiring itself out. Yosh panted before getting sleepy, sucking on his binkie as he drifted to sleep. 
With one last peep at Yosh’s cute ducky penis, shrunken and soft, it was just a little pink tip over his feathery balls. He diapered up his buddy with a duck-patterned nappy. “Class dismissed, but be quiet, baby is sleeping.” Nishi whispered as a chorus of crinkle butts walked out of the classroom at an irresponsibly early hour.
