Liam’s legs kicked impatiently in the office of the pediatrician. He’d told his mom that he should be seeing a ‘regular doctor’ once he’d found out the appointment had been made, but she protested; “no, no, I’ve gotten told from all the moms at the PTA meeting that this was the best doctor in town.”

It was a clinic Liam had passed maybe once or twice ever, despite living in the same town his whole life. “Peek-A-Boo-Boo” was on the sign outside, decorated with balloons and on the edge of town, away from any of the main roads or really much of anything. The office was covered in cute pastel colors; the nurses were dressed in flowery and primary colored scrubs- some of them may as well have been kindergarten teachers with their choice in clothes! Luckily nobody else was in the office at the moment.

“Liam Nero?”

He stood up, his hands sinking into his pocket. His mostly black fur melded with the hoodie; his bright red hair highlights and tail coloring were all that distinguished his other features; though he stood out against the bright, happy colors of the clinic.

He walked across the waiting area, his feet sinking into the foam block flooring with each step, when he realized his mom was following close behind him. He stopped himself with a heel-toe step, keeping his hands in his pockets, turning to look up at his mother; he’d always been a bit short for his age, standing at a whopping 5 '3".

“Mom, I don’t need you in there, I’m an adult.” his tone was placid, unemotional; a shot at sounding mature.

“Sweetheart, I won’t say anything, but I need to be there in case they ask about any medical history!”

“Who knows my body better than me?” Liam began to scowl, clearly upset by the challenge to his maturity.

“Let’s just do it together, come on sweetie,” she said, placing a hand on his shoulder and turning him around. He sighed and hung his head backwards, but followed the nurse with his mother in tow.

“You’re such a helicopter.”

The nurse, a well brushed shepard who reeked of what Liam was sure was baby powder, took his temperature, weight, age and other information. To her credit, Liam’s mother upheld her promise and stayed quiet; until the doctor showed up. There was a short rasp of knocks before the nose of a deer entered the room, nose and horns first. They were trimmed to keep from being terribly obstructive, but still gave him a clear and imposing silhouette.

“Oh, Dr. Cromwell!” Liam’s mother said giddily. Liam replied with a side-eye to his unreasonably excited mom, and then turned to face the doctor- but was… ignored.

“Mrs. Nero, yes, a pleasure,” he shook her hand. “So, tell me about Liam.”

He held a stylus to his digital pad and stared intently at the lioness.

“Oh, well, I read that brochure- do you know the Roo family? Bandaid’s mother gave it to me at the last PTA meeting, and I think this therapy may be right for my Liam!”

“Um… excuse me? Therapy? Mom-” he held his arms and shook his head, his neck arching in exaggeration, “what the fuck is going on here?” Without further input or even as much as a glance, Dr. Cromwell had reached into his pocket and pulled something out; in a single motion, the object had found itself into Liam’s maw. The mild taste of rubber and a squeak as his teeth tried to grind against the object told him a lot, but looking down showed him the incredibly odd reality; the deer had stuck a pacifier in his maw.

He went to spit it out, and aimed directly at the doctor, ready to peg him with it; but the deer’s hands grabbed his head and held him still. Between two lions and a buck, Liam never thought he’d end up frozen in the headlights.

Dr. Cromwell looked directly into Liam’s eyes as he shouted “Nurse!” Liam felt a cold shiver run down his spine; he began to suddenly salivate, his breathing getting a little faster, his heart a little racier. The door flung open, and the shepard from earlier entered, forcing Liam back against the examination table.

Liam’s first instact was, of course, to swipe and bite- rip and tear. His already red eyes flashed as he flexed his muscles; a high school senior, 18, left field for the school varsity baseball team- he was no pushover. Hours at the batting cages and workouts after class had left him with an athletic figure; he made up for his height in the ways he could, and gave the appearance of a scrappy sort of critter.

However, scrappiness wouldn’t save him here. Despite the flexing, he was forced back. Dr. Cromwell retreated for just a moment, reaching upwards as Liam put all his strength against both arms of the nurse, bearing his fangs and ready to strike. As his chest began to erupt with a powerful roar, his movement was suddenly stunted with a mask being placed on his face. Already in a rage, Liam was anything but focused on his breathing.

One breath; the smell of bubblegum and baby powder.

Two breaths; the colors in the room seemed a little brighter, the sun a little harsher as it crested through the window that faced the back of the clinic.

Three breaths; his muscles felt distant. He wasn’t quite able to connect them to his mind; he struggled to think, his angered brows unfurrowing and his jaw going a little slack.

Four breaths; he saw his legs and arms get strapped in. There was a blue strap, a green strap, a yellow one and a red one- heh, red. Liam really liked red.

Five breaths; “oh, that doctor… he’s talking to mom? Huh? What’s… going on?” he mumbled into the pacifier, and the nurse began to stroke his hair.

“Shhh, it’s okay little one, just be a good boy.” Her words were sweet like honey, singsongy and vibrato in a way that sent shivers down Liam’s neck. He lazily looked over at his mother and Dr. Cromwell.

“You see, this is what I mean. He’s just so aggressive at this age; I just want my little boy back. Do you think you can help me- help Liam, doctor?” His mother’s face was pleading, kitten-like black beads stared upwards, so sweet and wholesome.

“Oh, Mrs. Nero, this is all in line with what we deal with here. Now, did you have an idea on how far we should take him?”

“Well I was hoping we could mix and match a little? I read there were options for that.” She pointed to a few lines in the pamphlet; Liam had seen it on the counter a few days before, but had ignored it; now, he was about to find out what its contents boasted of firsthand.

Twenty breaths: everything was calm and the mask was removed. A strap was wrapped around his maw, but he barely seemed to notice. The pacifier felt good to suck, and made his tongue feel numb and silly.

“Ah, I see- yes, you’ve circled some things here, let’s see; got it. No more foul language, interest in cartoons and toys, removal of potty training, giggly hyper nature; yes, we can certainly make that happen. Give me just a few minutes, and I’ll have that first dose ready.

“Mmm… Mmm…” Liam couldn’t move, but he was able to make just enough noise for his mother to come over, taking over for the nurse and rubbing his hair herself.

“Oh sweetie, I know, it’s okay. Mommy’s here; mommy will always be here, and you’ll always be here with me. You’ll get to go on playdates and watch cartoons and you’ll need me every step of the way,” she cooed and clicked her tongue at him. Liam wasn’t cognizant enough to fully process this; how would that happen? He was going to university next year on a big sports scholarship! He’d be gone, and she’d be at home. No more dumb PTA meetings, or calls to the school- he was about to be totally independent, right?

The door was knocked on, and then opened again; the buck returned with a few things in hand, but Liam’s dizzy eyes couldn’t make sense of them from that distance. The mask got brought back down again, and he breathed in.

Breath 22; why did mom really bring me here? Liam thought.

The doctor placed a bag of fluid on an IV stand and quickly tested a separately held needle, flicking it a couple of times as a tiny amount of liquid spilled out. The doctor leaned in, twisting the cap of the pacifier and removing the button, placing a tube in it and having the nurse attach it to the bag of fluid.

“Listen Liam, I need you to be a good boy and listen to the nice nurse, okay?” The doctor adjusted his gloves with a snap.

The nurse made sure she was the only thing he could focus on; with one hand, she rubbed his shoulder, and with the other she held a puppet up; it was covered in glitter and had silly googly eyes, like it’d been crafted in a children’s art class. The silly eyes made Liam giggle, completely out of control.

“Okay Liam, ready? Swallow with your mouth and throat, but breathe with your nose when I tell you, okay? Here we go- swallow, Liam, swallow!”

The bright blue, almost neon liquid was more viscous than Liam had expected. It filled the paci and began to leak into his mouth. He didn’t have much of a choice, with his mouth strapped shut and his mouth salivating- he began to swallow.

“That’s it Liam, good boy. Swallow, swallow… breathe, swallow. What a good boy! You’re not going to use the potty anymore, are you? No, never again. You’ll just use your diapers like you’re supposed to! Swallow- keep swallowing! Okay, breathe. You’re such a good cub, and you love acting like one. You love being a little boy, you don’t ever wanna grow up. Come on Liam, swallow, this is the last of it, I know you know how to swallow!”

Liam gulped the liquid down as he was told; not only was it more thick than he was expecting, but it tasted almost sour, like a gummy worm without the sweet kick at the end. It was sharp and made his stomach churn as it filled so suddenly so quickly, Liam gulping down every drop- and then, he felt it. A jolt in his arm, and liquid going into his veins. He hadn’t even noticed that the band around his arm was tightened, and that his vein there was such an easy mark. He felt a rush; every color in the room was so bright, everything seemed to suddenly clear and race around him, as if he’d begun to spin faster than the planet itself, in a space between yesterday and today.

Then it slowed. He felt softer- like he was made of cotton candy. He tried to rub his arms against the exam table; the paper crinkled loudly, and he giggled, smiling as much as he could despite his entanglement. He tried to use used his legs to push himself up a little, but some wire had crossed- it wasn’t his legs he was flexing, though. His dark colored pants only slightly betrayed the ‘developing situation,’ but the puddle forming under him left no doubt. Liam was wetting himself- and his pants did little to help that situation. The hissing was loud, the puddle deep, and suddenly it was dripping and splashing down to the floor below the exam table. The nurse walked out of sight as Dr. Cromwell pulled a small flashlight, attached to a set of jingling keys from his pocket. Liam was fascinated by the sound, giggling and swishing his fluffy, dyed-red tail. The flashlight beamed into his eyes; they were a lighter shade of red now, more dull, less full of seriousness and swimming with curiosity.

“Well, that’s quite interesting! Mrs. Nero, your son seems to be experiencing what we call M.R.S Sensitivity. It happens in about one in every few hundred kids; your son is very sensitive to the serum. He’s going to take a little longer to get up to where you want him.”

“Wait, so he’s been regressed-”

“Yes, a bit further down. Maybe 3 or 4 years old?”

“Oh, I hate Barney… that’s what he loved to watch at that age. Are there any good shows you can recommend?” His mother queried, looking over the doctor’s shoulders at her son, who was squirming and confused and feeling his wet spot totally soak his pants. The nurse began the process of stripping him, and cleaning up the mess. As he was being wiped down, the doctor turned, smiled at the lioness and nodded.

“Oh, well, let me grab you this pamphlet here; this is from the BDF foundation, and they have some wonderful shows for little ones to watch. They’re one of our main contributors, so you can follow the link here in the corner to learn a bit more about them. They do wonderful work!”

Mrs. Nero smiled widely as she began to read up on how to sign up for the BDF television channel as Liam was laid back flat on the exam table. The band around his mouth was slowly removed and the doctor leaned in, moving Liam’s face around as the lion boy giggled.

“Liam, how old are you?” he asked.

What a question! Wow, Liam wasn’t quite sure. Was it… “‘dis many!” he tried to flex some fingers but, his hands were still incapacitated with his strapped down arms and legs; bound to the same fate, the same exam table.

“That’s right! That’s a good boy.”

Liam squirmed. He was being called a good boy; that felt… funny. He couldn’t place the feeling. It was warm, and it was around his crotch- it was that he went pott… somethin’. He went pee pee- that was it! It felt good to go pee pee… it felt REALLY good to go pee pee. It hurt so bad to hold it, letting it out was much nicer.

The doctor took a gloved, uncaring hand and reached down. The nurse had removed his socks, pants and boxer briefs and the doctor grabbed at his private parts. He nodded, making some notes on his digital notepad.

“Nurse, let’s get him ready to head home.”

Liam whined as he was being cleaned up; the wipe the nurse used was cold, but she continued to smile and promise him that it’d all be over soon. She wiped him down a few more times before lifting his bottom and then placing him down squarely in the middle of something big, fluffy, and crinkling much louder than the paper that lined the exam table. She pulled the front forward and Liam felt the same good, warm feeling come over that same area. He looked down; a diaper! Oh, wow, that diaper made him feel so good! It gave him that same warm feeling that peeing had, and as he joyfully kicked his legs, the nurse blew raspberries on his tummy.

“Oh you silly little goober you, if you’re a good boy and stay still for your diaper change, you’ll get a reward!” Liam shivered, from head to toe. He obeyed; he wanted to obey so badly. What was the reward? He was a good boy, he knew that, he had to find out.

The nurse smiled as she finally managed to tape the unreasonably thick diaper to his waist. It was covered in simple letters and numbers and happy characters that Liam recognized. He marveled over it as he sucked his empty pacifier wanting so badly to be able to touch it.

“You’re such a good boy Liam, here, let’s get your wrist and arm straps undone!” Slowly, they all became released, and instantly both hands found their way to the top and front of his diaper. It was so loud, so crinkly, so cute and colorful and fluffy and warm and perfect- it made him feel so good to touch it, but he didn’t know why.

“Ah, now see Mrs. Nero, this is another interesting phenomenon also associated with that reaction. A few wires can get crossed; physically, Liam is of course still 18, so he’ll still have that Libido. Professionally, I would recommend just letting him enjoy his diapers however he wants to and whenever he wants to. The good news is, this sort of reaction only goes to strengthen the connection between pleasure, and diapers. Your son certainly is VERY susceptible to our serum, I must say.”

“Oh, Liam! Hold your hands up sweetheart, I’ve got a friend for you! His name is mister buzz buzz, and he’s going to go right on your diaper so he can say hi- watch!”

The nurse led the wand right to the tent of Liam’s diaper- the pacifier did nothing to stop his moaning, whining through babbles as he went to grab at the magic wand.

“No no Liam, you have to keep your hands to yourself, be a good boy and listen nicely, I promise you’ll love your reward!”

Liam slammed his arms to his side; he had to be a good boy, he had to- there was no choice there. Good boys got rewards, and Liam loved getting rewarded for good behavior! But, if the buzzy wand wasn’t the reward, what was? The nurse upped the power and brought the wand back down on top of his tented, crinkly diaper. He was barely able to hear the conversation his mom was having with the doctor. Something about wipes and a crib… a carseat was installed during the appointment as requested? It was gibberish, anyhow- the wand felt so, SO good.

Liam groaned as his tummy grumbled- it was a different feeling than the one the buzzy was giving. His bowels suddenly tightened, he cramped, and his bound legs pulled as he tightened- then, finally, suddenly, with a massive crackle and fwump sound that everyone in the room had heard, his bottom completely gave up control as he filled the seat of his fresh diaper completely. A moment later, he found his tent throbbing and bursting and shooting load after load of warm stickies into his thirsty, hefty huggies. “D-DIAPERS! MY DIAPER! AH, DIAPY! AHHHH!”

Oh- that was the reward!

With his pampers packed, he laid back against the table. His tented diaper throbbed in an irregular rhythm as his bucking orgasm subsided. Liam laid, spent and experiencing an intense afterglow from the buzzing as the nurse stroked his inner thighs, making Liam squirm. He felt the weight of the sag in his seat as he lifted his bottom what small amount he could; his butt lifted off the exam table, but his diaper was loaded and weighed down by the mass he’d pushed, like the good boy he was, into his luvs.

“Okay Mrs. Nero, so, here’s the game plan. Bring him back every 3 weeks. Now that we know his sensitivity, we can adjust things from here. Remember, for the next few days he should spend very little time unattended. Keep him in a safe place, like a crib or a playpen, and make sure not to change him right away. Let him get used to the feelings and the smells and the sensations. If he starts to get a little fussy, we’ve included a buzzy wand in your take home box which you can collect from the front desk on your way out. If you call those folks at the BDF council, they can help with getting their channel on whatever cable or satellite television service you use. There will also be plenty of diapers in the take home kit but be sure to order some on those websites I mentioned once you put this little guy down for a nap. If you need remodeling or redecorating services, that number is also in the pamphlet for the BDF folks I mentioned. If there’s any other questions you have, please feel free to call the office and I’ll be happy to assist however I can.”

“Oh, Dr. Cromwell, thank you so much!”

The nurse reached into a nearby closet and unfolded a stroller big enough to fit Liam with ease; she did so as if she’d done it hundreds of times before. The nurse, with little effort, Lifted Liam and his mushy seat into his stroller; his bottom squished against him, but he didn’t seem to mind. It felt soft, it felt good, and he’d gotten a reward for doing so! He was SUCH a good boy, after all.

“Mmmf… goo’ boy…” he mumbled through his paci at his mommy.

“Yes, you were such a good boy! And you’ll stay a good boy for so, so long now Liam. You’ll be mommy’s good boy again, yes you will!”
