Big Brother, Little Brother

Hunter and Koda have swapped bodies! Whatever could this mean for them?


Hunter yawned and stretched his arms over his head, accidentally running his fingers through Koda's mane. He giggled and wiggled just a bit, feeling Koda's bare chest behind him. Koda loved using him like a living stuffed animal, cuddling with him every night and nibbling playfully at his scruff.

"Good morning, Hunter." Koda rumbled, licking the top of Hunter's head. Hunter smiled around the green and orange pacifier in his mouth.

"Morning."

"You're wet." Koda squeezed Hunter's diaper. Hunter reached behind him and felt the front of Koda's diaper.

"So are you!" Hunter giggled. "Koda's a baby, Koda's a baby." The older lion grumbled softly.

"Am not."

"Time for changies." Their mom said, walking in just then. "How are my two boys this morning?"

"Good." They answered in unison. She smiled.

"Well, let's get going boys. Down on the floor for changies!" Koda helped Hunter down onto the floor, where they laid side by side. Their mom smiled at how similar her sons looked, despite their age difference. "Let's see. Who should we start with?" Koda pointed at Hunter and Hunter pointed at Koda, both of them giggling. The lioness smiled, having expected as much from her boys. "I guess I'll just have to do you both at the same time." Koda and Hunter both smiled, each fairly eager to get out of their soggy nighttime diapers.

The lioness reached over and undid Hunter's diaper tapes before moving over to Koda's, each lion's diaper sliding down off of them from its own weight. Hunter glanced over at Koda's groin, which was considerably bigger than his own. Even if someone were to describe Hunter's current toddler cock as "fun-sized", it would be an exaggeration. Even fully erect, which it rarely was, Hunter's cock barely cleared two inches.

Koda's cock, on the other hand, was a good five or six inches, nothing above average for a lion, but Hunter could not help but feel a twinge of jealousy. Yet, despite being sixteen, Koda had not even a hint of pubic fur, but Hunter knew that that was due to his mom shaving the teenage lion.

Grabbing a paw of wipes, Hunter's mom went to work cleaning her two soggy boys up. Hunter and Koda squirmed in unison, but knew better than to actually resist the change. That only led to sore bottoms.

"Lift your bottom, Koda." The older lion did as he was told and he whimpered softly as the cold wipe went thoroughly between the cheeks of his butt. Hunter prepared to lift his own bottom once directed, but rather than wait for him to do that, his mom just wrapped her paw around his ankles and lifted his entire lower half for him. This took Hunter aback a bit. "Baby looks confused." His mom said as she wiped his bottom cheerfully. After all, this was not a messy diaper change, which would have been a different story. Hunter simply lay there, impatiently awaiting being re-diapered.

"Mommy?" Koda said.

"Yes?"

"Can I go try to use the big boy potty?" He asked. "I think I can do it this time!" The lioness smiled.

"Not right now, but you can try later, okay?" Koda considered this before nodding. The two naked lions watched as the lioness unfolded a diaper for each of them. Koda's was the Walgreens brand, rather plain white when compared to Hunter's Huggies with their babyish décor.

Quick as a jiffy, the two boys were powdered and diapered. Hunter giggled and looked over at Koda as they both sat up.

"Koda's a baby!" Hunter chanted teasingly. "Koda's a baby!" Koda rolled his eyes and nibbled at Hunter's ear. "Stop!" Hunter squealed.

"I'm gonna eat you!" Koda teased. Hunter squealed with laughter, trying to push Koda off while purposely letting him continue nibbling at him. Their mother watched with a smile, glad that her boys got along so well and were adapting to their new roles in the family.

"Alright, alright. You can eat your brother later. Mommy needs to get you two dressed."

"Can I do it myself?" Koda asked, a bit whiny for a teenager.

"Well, okay. But mommy will be right here if you need help." To Hunter's surprise, she handed Koda a shirt and shorts to put on. "Try your best." Koda took the clothes and set to work as his mom turned her attention to her younger son. "What should mommy's little Hunter wear? Hmm?" Hunter opened his mouth to reply, but his mom had other plans, pulling out a yellow onesie. "See? It says 'Mommy's Lil Sunshine'!" Hunter rolled his eyes, recognizing the gift that his aunt had given Koda back when he was still the little brother. Koda had never worn it, hating the color yellow, but it looked as though Hunter was about to.

"Mommy." Hunter whined.

"Hush. It's a lovely gift." She said. "You'll look so precious in it!"

"I don't wanna look precious!" Hunter moaned as his mom sat him up and slipped the onesie over his head, threading his arms through the sleeves. Koda, now dressed for the most part, looked away from his struggles with the button of his shorts to giggle at Hunter as his mom buttoned the garment around his puffy Huggies. Hunter looked down, his diaper sticking out of the onesie. Koda's shorts chose that moment to fall, re-exposing his own diaper.

"Mommy's two diapered boys." The lioness said, tugging Koda's shorts up over his diaper and buttoning them, leaving a rather noticeable bulge. "I think it's time for brekkies, hmm?" The boys both cheered. Koda dashed out of the room and Hunter made to follow him, but the lioness had other ideas, grabbing his arm and scooping him up. He tried to roar in frustration, but a baby's mew came out instead. His mom laughed. "Mommy's got you, pumpkin." She said, carrying him out of the bedroom, set against her shoulder.

They headed downstairs and to the kitchen, where Hunter was immediately deposited into the highchair. Koda started to make himself some toast as the lioness bustled about, making Hunter's breakfast. That was one of the nicer things about being the baby. No one expected you to do anything other than look cute. His mom came over with a bowl of oatmeal and Hunter made a face, not caring much for the stuff. She sat down and smiled.

"Try and get through it, sweetie. It's good for you." She said, holding a heaping spoonful up to his mouth.

"Can I have nakee time if I eat it all?" Hunter asked hopefully, his eyes wide and bright. She considered this proposal as she shoveled another two spoonfuls into the cub's mouth. Hunter ate them quickly, hoping to earn her favor.

"I suppose, but what happens if you piddle?"

"A spanking." Hunter said softly. "Does Koda get naked time too?"

"Yep, but with the same rules. Now, eat your breakfast." Hunter did so with aplomb.

After enduring a rather thorough face wiping, breakfast was at last concluded. Hunter bounced excitedly in his highchair.

"Nakee time!" He chanted in joyful anticipation. His mom smiled, the little lion trying to get out of his onesie even in his highchair.

"Give Mommy a second, sweetie." She said, focusing on cleaning up while also watching Hunter to make sure that he did not end up hurting himself in his exuberance. Only once she was done did she go over and release Hunter from his highchair. She carried the squirming cub into the living room and began to undress him to his diaper. Hunter, eager to be naked, tugged at his Huggies. With mommy's help, he was soon completely naked. He ran around in delight as she moved on to Koda.

"Chase me, Koda!" Hunter squealed. Koda obeyed, giving chase. Being a good deal bigger, it would have been easy for him to catch the toddler, so he made sure to stay slow and let Hunter keep a good distance ahead of him. Hunter squealed and squealed with laughter as Koda dropped to all fours and gave chase in a rapid crawl.

His fleeing was going great until he tripped over his own leg and fell forward. Koda playfully pounced, setting to work tickling his squirming prey.

"Stop!" Hunter tried to push his bigger brother's paws away, to no avail.

"Never!" Koda teased, his cock hanging down between his legs. Hunter noticed this and glanced down at his own prepubescent penis, which was dwarfed by Koda's adolescent one. Hunter blushed, but Koda's renewed tickling attack pushed that thought from his mind.

"Stoppit Koda!" He whined, concerned that he might make puddles and ruin naked time. To his surprise, that very thing happened. But he was not the culprit. Koda whimpered as a puddle formed between his legs, powerless to stop it.

"Uh-oh! Someone had an accident!" Koda looked back at mommy, who had stood up and was already heading to the kitchen for paper towels.

"I'm sorry, mommy!" Koda whined, tears in his eyes already. "I didn't mean to!"

"I know, sweetie." She said as she returned with a pawful of paper towels. "Mommy will get this all cleaned up and then it'll be time for you to go back into your diaper."

"But"

"But nothing, sweetie. Puddles mean diapers." She wiped up the puddle quickly and then gestured for Koda to lie down. Hunter stood up and watched as his mom began to diaper his former body. His paws slowly slid behind him and he felt his bottom, curious to see just how different it was. He smiled at how curvy it was. He did not mind his old butt, but this cubby one that he now had was vastly superior. The fur was soft and the butt itself seemed soft too somehow. Hunter was not sure how that could be, but it made perfect sense to him.

"Don't you go too far, little guy." His mom said to him. "You'll be next!"

"But, mommy! I haven't had an accident."

"Yet." She said. "Mommy doesn't want to risk it." Hunter grumbled. He wanted to be naked some more! He returned to investigating his bottom, reasoning that he should enjoy being naked while he could. Feeling a bit naughty, he decided to really experiment and cautiously probed his bottom with a single finger. He purred too softly for mommy to hear, sneaking a sniff of his finger. He could not describe the scent, but it smelled cubby.

Mommy finished up Koda's diaper and smiled at Hunter. He knew it was his turn so he docilely walked over and lay down to be diapered anew. He gave his insignificant cock one last look before the diaper was taped around his waist. He had a feeling that he would mess before he would see his penis again.

An hour or two passed. Hunter entertained himself with a few toy cars with Koda playing with him on and off. Hunter knew that Koda had his first football game that evening and wondered if he was nervous at all. He looked at the older lion, finding his thick white diaper a little strange, since when he had had that body, he had worn boxer briefs.

"Mommy." Koda said, drawing Hunter from his thoughts. "I wanna use the big boy potty." Hunter and Koda both looked at the lioness as she considered this.

"I guess it's worth a try." She said with a smile. She went over to the closet and pulled out the training potty, both Hunter and Koda gasping with happiness. It was forbidden for them to even touch the training potty, so it had become a welcome sight when Mommy or Daddy brought it out. "Ready, Koda?" The older lion nodded, squirming eagerly which looked ridiculous from an adolescent lion. Mommy set the potty down in the middle of the room and, taking Koda's paw, maneuvered him to where he should be. "Down goes the diapie!" She said musically. Koda giggled as his cock sprang free. "And down on the potty!"

"Okay, Mommy!" Koda said with a giggle, plopping his bottom down. Mommy buckled him up so that he stayed on the potty.

"You have ten minutes, sweetie." Koda nodded and got down to it, but was interrupted by the ringing of the doorbell. "Who could that be?" The lioness made sure that Koda remained on the potty before going over to the door. An adolescent bear stood on the porch with a big, friendly smile on his face. "Hello, Cam. You must be here to take Koda to the game, hmm?"

"Yep." He peeked around the lioness at Koda, who remained on the training potty, completely unembarrassed. "But I can wait."

"Come on in!" Mommy said. The bear complied. He smiled at Koda, but his attention quickly fell on Hunter, who sat there in nothing but his Huggies.

"Hey there, sport!" He said, kneeling down to Hunter's level. "Are you going to come play football?" Hunter stared up at the bear in confusion. Did Cameron know that he was the teenager before the swap? As far as he knew, only him, Koda, and his parents were aware of that fact.

"Huh?" He managed in confusion, the pacifier tumbling from his mouth. Cameron laughed, returning the pacifier to Hunter's mouth, his chubby cheeks moving as he sucked on it.

"I'm just teasing, little guy."

"You're so good with cubs." Mommy said to Cameron.

"My little sister Lily is about the same age as him." He pulled Hunter into his lap and bounced him gently. Hunter squirmed a bit. Cameron was one of his closest friends. Hunter remembered a sleepover that they had had when they were both seven, where he had learned that Cameron wore Goodnites to bed. He swore then and there to keep his secret forever. Now, here he was being bounced by Cameron and sucking on a pacifier in nothing but a pair of Huggies. He knew that in Cameron's eyes, he was just a baby, but something about it still seemed so very embarrassing.

Koda was just finishing up with potty time when Hunter felt Cameron pull out the back of his Huggies. He wiggled, but sat still for Cameron. What was he trying to find, he wondered?

"Someone's messy." Cameron announced, more to Hunter's Mommy than to the cub himself. Hunter blushed.

"Am not!" He mumbled into the pacifier, but he knew that that was a lie.

"I need to help Koda finish up, so would you mind changing Hunter, Cam?" Hunter's cheeks burned. Why couldn't Koda finish up on his own?

"Not at all." Cam said with a smile, setting Hunter down on his back on the floor. He watched Hunter gaze up at him while Mommy gathered the necessary materials for him, the little lion's face showing his embarrassment about the situation. "Here we go!" He said, reaching down and undoing Hunter's Huggies tapes. Hunter shyly sucked on the pacifier as Cameron undid his diaper. "Yuck!" Cameron exclaimed, holding his nose with one paw. "You destroyed this diaper, little guy!" He groaned, clearly regretting agreeing to this.

"Little boys tend to be worse than little girls." Hunter's mommy observed. "And I've got two little boys."

"Notta little boy!" Koda whined as mommy dressed him to go with Cameron to the school, where they would get ready to play that evening, his diaper leaving a large puffy bulge in his pants. The lioness kissed his cheek and patted his bottom.

Hunter squirmed with embarrassment as Cameron began to work. His best friend was changing him! He could not even comprehend that, in a way. He had known Cameron since preschool and possibly even earlier, yet he was the epitome of maturity as Hunter lay there, itty bitty penis exposed as he waited to return to Huggies. He shyly sucked on his pacifier.

The bear grabbed a few wipes and went to work on ground zero, Hunter's cubby bottom. Hunter breathed a sigh of relief, not yet ready for Cameron to actually touch his cock and balls.

"You're so thorough." Hunter's Mommy said. "You must change your sister a lot."

"Yeah, I've never really minded changing babies." Cameron said with a benevolent smile.

"You're three months younger than me." Hunter grumbled grumpily, even though it was not true anymore. Regardless, he was not a baby.

"Just be sure to be as thorough with his front."

"Diaper rash wouldn't be much fun there!" Cameron chuckled as he gently cleaned Hunter's balls. Hunter squirmed and blushed, but Cameron kept him under control quite skillfully. For a fleeting moment, he wondered if Cameron had ever changed Koda's diaper, but the thought quickly passed when he noticed, along with everyone else, that Koda was absent-mindedly sucking his thumb. Koda blushed and pulled it out shyly.

Cameron took the powder and skillfully covered Hunter's diaper area with it. Hunter smiled as the lovely scent made its way to his snout. Cameron noticed and smiled at him.

"Don't enjoy that smell too much, Hunter." He said. "Otherwise, you'll end up in diapers forever, like your big brother!"

"Hey!" Koda blushed, but everyone knew that Cameron was just teasing. To Hunter's surprise, Cameron suddenly began to undo his belt. "Be a big boy, like me!" He unzipped his fly and tugged down his pants to show Hunter his blue striped briefs. Hunter could not help but stare at Cameron's bulge, as big as his own was before he and Koda swapped, if not slightly bigger.

"Male lions tend to have some trouble being potty trained, but most succeed by first or second grade." Hunter and Koda both blushed as their mommy explained that. Koda still wasn't potty trained due to the swap bumping him immediately up to sixteen and before the swap, it had taken Hunter until third grade to stay dry all night.

After pulling his pants back up, Cameron patted Koda on the bottom like teammates tended to do.

"Coach will kill us if we're late, so let's go." He said, leading the way out the door. Koda waved good-bye and followed.

"Just you and me now, munchkin." Mommy said, picking him up and patting his bottom. "I used to change Cameron's diapers, so it's cute to see him changing yours." Hunter squirmed in Mommy's arms and she nuzzled him.

"Mommy!" He whined. The lioness smiled and kissed Hunter's forehead.

"Hush, baby. Mommy's here." She laid him down on her lap, rubbing his stomach with one paw while undoing her blouse with the other.

"What are you doing?"

"Feeding my baby boy." Mommy said. Hunter squirmed as she revealed her white nursing bra. Even as a sixteen year old, Hunter had never seen a pair of breasts in person and he blushed as it occurred to him that the first pair he did get to see was his mother's. He whimpered softly.

"What's wrong, Hunter?" Mommy asked, her maternal ears hearing even the softest whimper of her cub.

"I kinda wanted Tani's breasts to be the first ones I saw." He mumbled, a bit ashamed of that. His mom laughed, but not unkindly.

"I think you're a long way from seeing another girl's breasts." She patted his bottom as she lifted him up to her breasts. Hunter reached out and touched her breasts cautiously. She smiled and undid her bra, exposed the nipple. She lowered Hunter to it and it brushed his lips. Instinct took over and he began to nurse.

Hunter nursed for a while before the doorbell interrupted the scene. He tried to pull away, but Mommy kept him up against her breast as she rose to answer the door.

"Vitani! Come on in!" She said. "Koda will be ready to leave in just a moment." Vitani smiled at the nursing lion and stepped in. Out of the corner of his eye, Hunter saw that Tani wore a tight school t-shirt and a skirt that fell to about mid-thigh, an outfit that would have driven sixteen year old him wild.

Mommy lifted Hunter away from her breast, unconcerned with covering up as she wiped Hunter's face and checked his diaper.

"He's a little damp, but he can wait for a change." She said, sitting Hunter on her lap as she clasped her bra shut, leaving it exposed as she continued to instruct Tani. "I've packed a diaper bag for him." She gestured toward the Barney diaper bag by the door. "If he gets hungry, there's a bottle or two in there for him." Vitani nodded and lifted Hunter off his Mommy's lap.

"Ready to go watch your big brother play football?" She asked. Hunter felt her check his diaper.

"Oh, one last thing." Mommy said, grabbing Hunter's jersey from nearby. It was a diminutive version of the jersey that Hunter had worn prior to the swap and that Koda would be wearing on the field. Vitani held Hunter as Mommy gathered the shirt in her paws. "Touchdown position, dumpling!" She smiled as Hunter immediately raised his arms straight up, allowing her to slip the shirt down over his cubby frame.

"How cute! He's like a mini Hunter!" Tani gushed. Mommy nodded and kissed Hunter's cheek.

"You be good for Tani, okay?"

"Okay." Hunter said softly. Mommy slipped a pacifier into his muzzle and kissed him again. Shouldering the diaper bag, Vitani carried him out to the car.

Vitani was more than able to set the cub in his car seat, smiling at how he instinctively tested the straps that held him in.

"You won't be escaping it easily, Koda." She said, stroking his cheek fondly with her paw. He smiled.

"I don't wanna escape." He explained. "I just want to be comfortable."

"Oh!" Vitani laughed. "My mistake."

The drive to the high school proved uneventful. Vitani checked on the cub every now and again, but it was not a long drive, so nothing came up.

Vitani parked the car in the parking lot and Hunter gazed out the window at the familiar sight of the high school's football field's lights towering close by.

"All set, kiddo?" She asked, gazing at Hunter through the rear view mirror. Rather than wait for an answer, she walked around to the back door and took Hunter out of his car seat. "Let's go watch Hunter score a touchdown!" She said, nuzzling the cub's cheek. Their seat in the bleachers was surprisingly close to the field and Hunter looked forward to the game eagerly. He hoped that Koda would not embarrass him, though he was not entirely sure how Koda would embarrass him anyway. Tani set him in her lap, nuzzling the top of her head in an unmistakably maternal fashion. Hunter smiled, feeling her warmth.

The first quarter passed without incident. Hunter's former team led by a touchdown and Koda was playing fairly well in spite of the thick, obvious padding under his pants. Hunter wondered absent-mindedly who changed Koda if he had an accident during the game. He remembered suddenly that that was his body down there and he hoped that he would not find out the answer.

Motion brought Hunter out of his thoughts as the second quarter began. Hunter looked up at Vitani curiously as she put him down on his back on the bleachers. What was she doing? Why was she not taking him to the bathroom? He wiggled a bit, but Vitani simply smiled and began to undo his diaper right there in the stands!

"Tani?" He said around the pacifier, but the crowd suddenly cheered and she did not hear him. He turned his head to look at the field and realized that Koda was playing again. He tried to focus on that fact instead of his impending public change. He yelped childishly and in a decidedly non-masculine fashion as the crisp autumn air touched the damp fur around his cubby cock. Tani smiled to reassure him and started to wipe him down. Hunter whimpered and squirmed, but Tani was more than prepared for that, keeping him still as she lifted his legs and wiped his bottom, which jiggled slightly.

"Your bottom reminds me of mine." Tani remarked off-hand. Hunter blushed, having noticed over the past few days that Koda's body's bottom was more feminine. He passively wondered if he had looked as feminine when he was Koda's age, but he immediately dismissed the thought as ridiculous.

"Touchdown, Pride!" The announcer declared, the crowd cheering. Tani forgot about Hunter for a moment and jumped up, cheering. Hunter squirmed, feeling terribly exposed being naked from the waist down. He tried to get Tani's attention, but she was focused solely on the extra point attempt. "And there's the extra point."

"Tani!" Hunter whined. The lioness gasped and hurriedly sat back down.

"I'm sorry, sweetie. I got a little caught up in the excitement there for a moment." Hunter fumed a bit, but he knew he could not stay mad at her. She lifted his legs again and double checked his bottom.

"I'm clean." Hunter grumbled. Tani ignored him and slipped a fresh diaper under his bottom. In a jiffy, he was heavily powdered and taped back up, much as he had been countless times before. Tani rebuttoned his onesie before returning him to her lap.

Halftime approached and it was not long before time ran out in the second quarter. Hunter's former team was leading, much to his delight from his vantage point on Tani's lap. He looked up at the lioness, who kissed the top of his head affectionately. He tried to kiss her back, but she was too high up. Tani giggled, but before she could help him, their tableau was interrupted by a meek voice.

" Tani?" They looked up as one and saw Koda sheepishly standing there. "I needa change."

"Oh?"

"I'm a stinky lion." Koda said a bit too loudly for Hunter's tastes. After all, his body had a certain reputation that was already threatened by Koda's obvious diaper bulge. Tani chuckled.

"Well, lead the way to the locker room, champ."

"What are you talking about?" Hunter whined as Tani stood, picking him up along the way.

"We can't change the star football player's diaper right here!" Tani said, nuzzling Hunter's cheek. Hunter grumbled. Both she and Koda were talking way too loudly for his liking. He had a reputation to maintain!

Tani followed the waddling teenager down off of the bleachers and they took the familiar path to the locker room. Hunter's nose twitched as he smelled the distinctive smell of the boys' locker room, a combination of body spray, deodorant, and various body odors. Despite the fact that it was a boys' locker room, Tani followed Koda in as though she owned the place. Oddly, no one seemed to find her presence out of the ordinary in any way. The players, in various states of undress, hardly even looked up as Koda led Tani over to his locker. Hunter squirmed nervously as Koda stretched out on the floor, smiling at Tani. He looked like such a baby.

"Gonna have to set you down for a sec." Tani said to Hunter, setting him down next to Koda. Koda took Hunter's paw and held it as Tani eased his pants down his legs. Koda's diaper sagged, clear evidence that he was both soggy and messy.

"I'm a stinky baby!" Koda giggled. It sounded so strange coming from a teenage lion's mouth. A few of the other players snickered behind their paws, but a glare from Tani silenced them. The maternal lioness was not someone they wanted to anger. Rumor had it that she had diapered the adolescent lion as some sort of punishment, after all. They shuddered and averted their eyes. A chorus of groans echoed off the walls as she untaped Koda's diaper.

"You are indeed." She said, but she seemed entirely undisturbed by the stench. She filled her paw with a bunch of baby wipes. Yet, when the time came to wipe Koda's penis, she blushed a little. Hunter noticed and wondered why that was. He realized it might be because she was attracted to the teenage lion. Summoning her courage and biting her bottom lip, she set to work.

Hunter sat close by Tani, watching her work on his former body. None of his old teammates seemed to care much about Koda getting his diaper changed right in their midst, except for the smell. He looked around at all the muscular teenagers in their boxers and blushed as he remembered that he was just a little baby in Huggies.

Before long, Koda was in a fresh diaper. Patting his bottom, Tani helped him get dressed again as Hunter looked on, blushing at how normal this all seemed to the rest of the team. He wondered what sort of ramifications this would have, were he and Koda to swap back again at some point soon.

"Come on, baby." Tani said, scooping Hunter up. "Let's let your big brother get back to playing football."

The remainder of the game went by quickly. Hunter's former team managed to win by a narrow margin and before Hunter knew it, Tani was getting him all buckled into his car seat again.

"Your mommy's going to have a nice, warm bath ready for you when you get home." She said with a smile, nuzzling the soft downy fur between the cub's ears. She turned and saw Koda coming toward them, waddling slightly.

"Tani! Can I have a ride home?" As Koda drew near, they could both tell that he had not showered with the team.

"Sure thing." Tani said. The drive home was mostly uneventful, although Koda kept tickling Hunter, who squealed and squealed, terribly ticklish.

They pulled into the driveway and Hunter saw Mommy standing on the porch, waiting for them. She took Hunter from Tani and sniffed the air.

"Looks, and smells, like you'll have a bath buddy tonight, baby." She said to Hunter. Koda giggled as though that had been his plan all along. Carrying Hunter, the lioness led Koda straight to the bathroom, where she had already filled the tub. "Let's see, who should we undress first?" She set Hunter down on the counter and unbuttoned his onesie, revealing his damp Huggies. Those soon ended up in the garbage and Hunter sat right at the mirror, completely naked, his chubbiness making it difficult to notice his itty bitty penis.

Meanwhile, Mommy had Koda down to just his diaper and he flexed in the mirror. Hunter immediately noticed the stark difference between Koda's muscular body and his pudgy, roly poly cubby one. The differences only grew more apparent once Mommy removed Koda's diaper and his seven inch cock came into view. He stretched nonchalantly as Hunter blushed and shyly covered his own groin. Koda and Mommy at least pretended not to notice.

"Can we play in the tub first, mommy?" Koda asked, his cubby turns of phrase sounding quite odd in his deep baritone. "We wanna, don't we?" He said, looking at Hunter expectedly. Hunter nodded meekly. The lioness smiled.

"I suppose you two can, but don't flood the bathroom. No splashing!"

"Okay, mommy." Her two cubs said in more or less unison. She chuckled, carrying Hunter over to the bathtub and setting him into his bath chair, specially designed to keep little cubs from one place in the tub. Koda freely climbed in, the water rising to compensate. Hunter playfully splashed a bit.

"Don't get too carried away." Mommy said, giving the little cub a love nip. Hunter giggled and playfully batted her away. "Mommy will be back in ten minutes, boys. Play nice." With that, she left them to their play.

"What should we play?" Koda asked. Hunter shrugged, squirming a bit in his bath chair. He wanted to be free like Koda, but Koda did not seem to notice as he sat on the opposite side of the tub, idly sucking his thumb. His other paw slowly slid down his abdomen and Hunter suspected that he knew the final destination of it. "Do you miss your weewee?"

"I still have one." Hunter replied, pointing down to his itty bitty member.

"Yeah, but this one is a lot bigger!" Koda said with wide eyes, as though he could hardly even believe it. He lifted his pelvis slightly, as if his brother was not intimately familiar with the penis that he now had. Koda, thumb of his left paw still in his mouth, used his right one to make his penis wave up and down. Hunter blushed. His brother looked far more like the textbook definition of a lion than he did. That much was for sure.

"Stop!" Hunter whined bashfully. Koda giggled, but complied, still sucking his thumb as he began to maneuver a toy boat around the tub. Hunter found one of his own and followed suit. When Mommy returned, they were just playing with their boats, making noises and just having fun.

"Let's get my boys nice and squeaky clean." Mommy said, smiling at the tender scene before her. She kneeled down by the side of the tub, wetting a washcloth. "Who's first?" Both Hunter and Koda pointed at the other, so Mommy chuckled and started in on Koda first, much to Hunter's delight.

"I can wash myself!" Koda protested, but Mommy just ignored him, lifting his arms to make sure she eliminated the adolescent stink, replacing it with the baby powder scent of Johnson and Johnson tears free cub shampoo. Koda wiggled, basically an oversized cub. Mommy chuckled and kept washing him as Hunter looked on, unperturbed by his large cock, unlike Tani.

"Set a good example for your baby brother." Mommy gave Koda's thigh a good smack. He yelped and complied, remaining as still as he could as Mommy thoroughly cleaned him, going so far as to give his mane a detailed shampooing. "All nice and clean!" Mommy cooed, kissing Koda's cheek.

"Now baby's turn!" Koda said, giggling. Hunter mewed in surprise as he realized just how right Koda was. Mommy shifted slightly and set to work on her younger cub.

Hunter was small enough that Mommy could easily hold him with one paw and wash him with the other, giving him quite the scrub-down, without ever being needlessly rough. Hunter shyly glanced down at his groin, reminded once again just how small it really was. He looked over his shoulder and saw his rump, setting eyes once again on his frankly feminine bottom. He blushed as he looked across the tub at the paragon of masculinity that he had once been, who was playing with his toy boat and sucking his thumb. It seemed so incongruous.

Physically being the baby was one thing, but Hunter still found so many of the side effects, as it were, to be strange. Koda was the one now who got the letters from colleges trying to court him for the collegiate leagues. Hunter received letters from Pampers and Huggies, asking him to come and audition for their commercials. He suspected that Mommy would be scheduling some try outs soon and he was not sure how to feel about it.

"Alright, boys. You're both squeaky clean!" She helped Koda out of the tub and wrapped a towel around his shoulders. She then returned to the tub and lifted Hunter out, nearly swaddling him in a second towel before giving him a vigorous rub-down. She cooed down at him as Koda came over and joined his mom in cooing down at his baby brother. Hunter blushed and squirmed in his towel, which only made them coo at him more. He felt so small as Mommy carried him out of the bathroom to get him diapered and ready for bed.

Epilogue

Hunter snored softly, but Koda was awake, his baby brother warm against him. Both of them wore nothing but their diapers. Koda knew that Hunter had usually worn underwear when he had been the big brother, but he was unable to use the potty like Hunter could. Mommy did not seem to have any thoughts about potty training him, as though he had always worn diapers. He wondered if that was one of the side effects of their swap.

Hunter, still asleep, grunted softly and Koda's sharp ears heard the sound of the little cub's diaper expanding as he messed himself. Koda giggled softly, covering his mouth with a paw to muffle the sound. He knew Hunter would not be happy if he found out that he had messed in his sleep again. He looked around the room, not sure what to do. Suddenly, an idea came to mind.

Slowly easing himself away from the sleeping cub, Koda waddled over to the closet, where the extra diapers were. His own diaper was a bit soggy, but it would hold until morning. He preferred to let Mommy change him. He would change Hunter though. It was his duty as the big brother, after all. The only sounds in the room were Hunter's snores and the sound of Koda's crinkling diaper as he silently padded back over to the bed, easing the blankets away so that Hunter's diaper was readily accessible.

Crawling onto the bed, Koda kneeled in such a position that Hunter was between his legs. The cub stirred a bit, yawning and stretching a bit before settling back into sleep. Koda could not help but smile. Reaching out, he slowly undid the tapes on Hunter's Huggies.

"Hmm?" Hunter said. "Wassat?"

"Shh. Go back to sleep." "Imma 'tinky baby."

"Yes, you are. Go back to sleep, Hunter."

"Not Hunter. I'm Koda!" Hunter said with a giggle, still half-dreaming. Koda shrugged and let the little cub keep mumbling nonsense as he began to clean him up. Koda had been on the other side of countless diaper changes, so it felt strange to be the one doing the changing.

"I can see your weewee." Koda teased in sing-song. Big brothers were supposed to tease their baby brothers, after all.

"It's itty-bitty." Hunter said with a giggle. "Imma baby!"

"Yes you are." Koda agreed, lifting Hunter's legs and wiping his bottom as thoroughly as he could. He knew firsthand how bad diaper rash could be and did not want to subject his poor little brother to that.

Having finished wiping Hunter, Koda carefully slipped a new Huggies under his cubby rump. Koda wondered idly if his butt had really looked like that before. It reminded him of Tani's bottom. He purred as he felt his penis stir in his diaper. He liked that Tani made him feel that way. He was not sure why. He stared into the darkness for a second, remembering how good it made him feel to have Tani wiping him in the locker room.

"I'm cold." Hunter whined, waking up more and more. Koda pulled himself from his thoughts and lowered Hunter onto the diaper before quickly powdering him. He proved a bit too hasty and accidentally powdered the bed around Hunter's diaper area as well. Thinking quickly, he wiped the excess powder up as much as he could and wiped it on both his and Hunter's tummies. "Something smells like baby."

"It's you. And me." Koda whispered. "Now shush and go to sleep. I'm almost done."

"I'm little mister puffybum!" Hunter exclaimed as Koda taped the diaper around his waist. Koda slipped a pacifier into Hunter's muzzle, hoping that Mommy did not hear his outburst over the baby monitor that stood attached to the headboard. He returned both himself and Hunter to under the blankets and kissed Hunter's forehead.

"Good night. I love you." He whispered.

"Love you too." Hunter mumbled, almost asleep already.
