Willing to do anything to further his academic career (and avoid his home), Todd is paired to take care of Nick, one of the school's 'special cases'. Surely a few hours after school won't hurt anything, will it?

A commission for the wonderful Coolguts on FA


Todd felt, like most teens, out of place in his family. Now in most cases it was simply teenage angst, the universal 'You don't understand, daaaad' that courses through the veins of every fur as they went through those strange years. But for Todd, he just didn't fit in with the Robinsons at all. He was short, while the rest of his family were all over six foot. They all had broad shoulders and bulging, veiny muscles, even the females, while his muscles were barely a bump on his arms and legs. He wasn't bad looking at all, but set next to them he paled. They always spoke of sports and working out, they were crass and rude and loud and honestly not all that smart. While they all languished downstairs, stewing in their post-workout sweat watching serial flicks, he would be upstairs with his books and his telescope, gazing in wonder at the glorious sea of stars twinkling in the twilight.

They didn't bully him because he was different. The people at school did, they took his glasses, teased at his flannel shirts, but at home they just kind of forgot he existed. Somehow, this was worse than bullying. This was non-existence. This was lack of importance. So rather than stay home, watching his brothers and sisters work out, shoot the shit and wrestle, he spent as much time as he could at school. He'd rather bare the occasional teasing snicker than have to go home, where he did not belong and would rather not exist.

That's what brought him to school the first Friday of his senior year. While most of his classmates and even his few friends were out partying, forgetting the return of the yearly grind, he stayed after in his homeroom teacher's course. It was extra credit, would look good on a college application, and most importantly to him, would be something he would enjoy. He had the chance to be a science tutor, specifically astronomy. And that's where he met Nick.

'Met' probably isn't the right word. Todd had been aware of the cat for most of his high school career. Occasionally the two would meet in the hallway, Todd would nod uncomfortably and Nick would let out a long, gurgling... noise. Nick was a nonverbal 'special' student, and had been since fifth grade, when an unfortunate accident left him in diapers and with an IQ approaching that of a mobile potato. Nick was one of those people that Todd would try to forget existed, if only to make himself that much less self-aware of his luck.

And here he was, face to face with him. Nick gurgled, his neck twisted at an odd angle, as if he had broken it. That was just the way he was, though.

"Todd, you know Nick, right?" The science teacher, a black jackal, smiled pleasantly, likely glad that he didn't have to deal with him. Todd nodded slowly, a polite grin plastered to his face.

"Yeah." He said. He offered his hand to the cat. "How do you do?" The cat did nothing but stare at it.

"Todd." The teacher's voice was more stern this time. "You know that he can't speak. Now, you agreed to be his after-school handler for a few weeks while his main one is gone, and to fill in during school a few days a week. You're going to be with him for a few hours today, and his parents will be here after to pick him up. Understood?" Todd nodded with a slight sigh. "Good." The teacher left the building, leaving the door slightly ajar behind him.

The two were alone in the empty room. Todd finally had a moment to study Nick properly; they always bumped into each other and passing, and so Todd only had a vague recollection of Nick's face and general build.

Had things gone differently, Nick would have been a lady killer. Even now, when his mental capacity was so dimmed that he could barely walk properly, he was quite handsome. He had a strong, square jaw lightly furred light brown, just like the rest of his body. There were little specs of cream added in here and there, but for the most part, he was a solid color. His shoulders were broad and there was a little muscle on his upper chest. He was dressed well; all in all, he was conventionally attractive. Almost.

In pictures, he appeared fine unless you knew what to look for. He tended to hold his head at an acute angle, appearing uncomfortable with it at all times but not having the mental capacity to realize he should right his head. His back was hunched and twisted from the way that he sat, and he always wore this wide, goofy smile. It wasn't one of the good ones, the 'boy next door' type smile. It was goofy, mostly gums with a little white in there, and it seemed to take up his whole face, forcing his eyes to scrunch nearly shut. His arms seemed to bend only at sharp angles, in this case his shoulders at forty-five degrees in, his elbows straight up, and his angular, arched paws playing with his cheek idly.

Probably the biggest indicator of his mental problems, however, was not in the way that he held himself. From the belly up he looked well dressed; sharp shirt, a few bracelets, well groomed fur. But below that... Nick eschewed pants and underwear, and in its place he wore a single, massive white diaper. It had blue tabs on the sides and was the classic representation of proper padding. It was extremely thick, forcing his legs apart with a full foot of absorbing material when dry, and he was very rarely dry. The cat took pride in making that thing fill right up, destroying it if he could, filling it with piss and shit until the back was brown and sagged past his knees, and the front was pure yellow and puffed out two, two and a half feet in front of him. Once it started leaking shit and piss everywhere he let out a beleaguered whine, and one of his attendants changed him, wherever he might be.

The silence between them grew uncomfortable for Todd, though he knew Nick would not care.

"Erm... shall we, then?" He said professionally, standing and motioning for Nick to get up. Nick understood, to Todd's surprise, and they made their way up the stairwell, the sound of the cat's crinkling padding filling the hallway. At the top of the round stairwell was the 'special' room where all of those kinds of kids went after school. Today it would just be the two. Nick started up first, and Todd headed up the rear. Luckily for Todd, the padding was entirely new, and so he figured he wouldn't have to deal with clean up nor the smell.

They reached about halfway before Todd was proven wrong.

It started with a short burst of gas slipping out between steps, when the beefy cat's cheeks were spread the most. Todd scrunched his nose, waving them away mentally. They were just farts, after all, nothing more. They may stink, but all farts stink.

They became wetter and wetter as time went on, and Todd began to grow desperate to reach the top. He couldn't deny it was coming anymore. His eyes flickered ahead-- it was the door to the observatory.

"Almost there!" He said too loudly. Nick stopped in his tracks, letting out a long, wet fart that didn't seem to end. Todd paled beneath his fur, gagging at the smell. "N-No. Nono, bad. Bad bad bad, open the door, open the-!"

The burst of gas cut off suddenly, replaced by a loud crackling sound. Nick's eyes rolled back, and he wore an empty grin on his face as his ass jutted out. His padded rear bulged straight out in a mound, reaching an almost comical size before sliding down his taint. The fabric turned a greenish brown as he continued to fill his diaper, the cat's shit swelling the back up. The front began to swell too, a quiet hissing sound causing Todd's ears to flick back.

The air was thick and muggy as the smell of shit filled it, Todd wavering on his feet as it engulfed him. It clouded his thinking as he struggled to deal with this assault on his senses and his decency, and while he could see the air was clear, the stench made everything seem hazy to him. In reality that was his eyes tearing up. He couldn't speak though he tried, his voice catching in his throat. He was afraid to step back down the stairs, thinking he might fall. There was nothing he could do but stare as that massive white diaper soiled, sagging down towards him like a killer stalking his prey.

"Nick, Nick no!" Todd said as the diaper finally pressed up against his face. He could have sworn Todd pushed his ass back in response, forcing the tiger's snout deep into the brown, oozing plastic. Todd couldn't breathe, couldn't think as it surrounded him, the smell seeping into his lungs and the grease into his fur.

Finally, after several unbearable minutes, the retarded cat crawled up the last few steps, leaving a trail of shit drool as he went. Todd stood there, gagging and groaning as he tried to recover. Each step that disgusting stench took away from him the better-- he would have to take a shower when he went home.

He wasn't fully recovered when Nick started to whine and gurgle, banging firmly at the door. The tiger shook his head, struggling to clear it, and wearily made his way up the ooze-covered steps. "I'm coming, I'm coming," he groused, unlocking the door and letting the diapered cat in.

It was damn near impossible to get around that diaper. Who could even shit and piss that much? Almost a foot and a half of brown and yellow fabric bulged around the dumb cat in every direction, even pushing up his belly at the same time as sagging to his knees. It's not natural, Todd thought. Maybe it was sort of making up for the lack of brain usage.

Nick crawled into the room with glee, immediately working his way towards his favorite toy. It was a large circular room with a vaulted ceiling, painted a sickly green to match the carpet and the drapes over the single window. Todd figured it must have been some interior designer's idea of 'happy and uplifting', but it also served the purpose of displaying plainly any filth or dirt.

Along the wall were cubbies of toys and blankets of various shapes and sizes, ranging from simple wooden blocks to complex electronics for the nearly mentally competent, and a large television. It was off for now, but a game console was hooked up to it. Todd felt somewhat jealous; Nick got to stay here all day most of the week and still pity-pass all his classes, whereas he busted his ass and still struggled sometimes. What he wouldn't give for a day off, just playing with toys and games.

Speaking of Nick... the cat was starting to leak onto the carpet, bouncing in his shit as he made two spaceships crash into each other. Todd groaned. He would have to change his ward before his parents arrived, so he might as well now. His eyes flicked to the other side of the room. Here, the cubbies were filled with diapers of all sizes and colors, including several absolutely massive ones. They were about a foot thick folded up, meaning they would add six inches to anyone wearing them. As for how much they could swell... well, Todd was quite familiar with exactly how much use Nick got out of them.

"Alright, Nick. Come on over here." Todd said as he went to the cubbies, pulling out a pure white diaper of the largest size. It was surprisingly hefty-- no wonder Nick had the thighs of a bull. He looked up to see Nick staring at him, chewing on a toy and making no moves to come hither.

Fuck.

"Fine, I'll change you over there." Todd gathered the baby powder, some wipes, and located the trash can, dragging it to the center of the room. "Now lay on your back. I know you can do it, I see you get changed all the time." He wrinkled his nose, standing so close to Nick. He had gotten used to the smell somewhat, but it still made his mind somewhat hazy. He didn't like it.

Nick let out a giggle, squishing in his diaper and throwing the toy at his caregiver, who dodged it with ease. "Fuck, Nick! Just lay down!"

The cat began to whine, but while that would melt the hearts of most of his caregivers, Todd wasn't having any of it. He growled to himself, dropping the supplies and to his knees, grabbing Nick by the shoulders and trying to force him to his back.

Oh, how Todd wished he worked out with his family now. Nick was much stronger than even his wide shoulders suggested, and the tiger's entire struggle was essentially him grunting, groaning, and putting his all into the cat's chest, who continued to whine and stay straight up, not even wavering.

Eventually, Nick had enough of this! He just wanted to play, but his stupid tiger friend just wanted gross diaper changes. The cat grabbed Todd by the shoulders and pushed him to the ground. The tiger couldn't resist, surprise stunning him for the moment, and before he knew it the diaper-wearing feline was straddling him, drooling on his shirt.

"F-Fuck, gross man! Get off!" Todd protested, but it did nothing as Nick crawled up him. His diaper dragged behind him, enveloping Todd's lower body in a soft, gooey warmth that the plastic did little to stop, the ooze soaking into the fabric of his clothes. That warmth moved up as the cat did, enveloping his crotch, pressing against his belly, soon his chest.

Todd continued to writhe and struggle, but it became harder and harder as the diaper got closer, his mind fogging from the strong, sharp smell and his crotch feeling... strange. The wetness continued to move up his body, and Todd's eyes grew blearier and blearier with each inch Nick moved up. He could feel his thoughts slow down, peter out into nothingness. He became acutely aware of his body, how nice that warm weight felt on his crotch... on his belly now. How nice it smelled. No longer was it nauseating, but it was actually calming.

By the time Nick sat on his chest, drooling directly into Todd's mouth, the tiger was just panting and groaning, bleary eyes staring straight up as his open mouth gargled Nick's drool. It ran over the side of his lips onto his cheeks.

The two stared at each other for a while, Nick happy to play with his new friend. The cat would let a thick strand or two of drool drip into Todd's mouth, and the tiger in turn would gurgle or moan, letting it slosh over the sides of his mouth. This could have continued on indefinitely, the two stuck there in some mindless game until relief came to save the tiger. It could have been so, had the tiger not slowly came to, just for a moment.

His brows furrowed as his conscious mind fought through the haze in his brain. He gulped down the drool with a shudder, the thick, warm liquid settling heavily in his stomach. "I, uh, Nick... Nick? Nick! Get the fuck off me!"

Nick let out an unhappy noise. His friend was being mean again! As punishment, Nick scooched forward, settling his diaper on top of Todd's half-open mouth.

The taste was indescribable. The feel, revolting. The smell, overwhelming. Todd tried to scream at Nick to get off, but the words were stopped at his open lips, deadened by the shit-filled plastic fabric pressed against them, sealed perfectly well. He tried to lift his arms, push the cat off, but he couldn't find the strength, his will and energy leached away both by the stench and lack of oxygen. By the time Nick lifted his groin to look at Todd, wondering if he's alright, the tiger was gone, mentally, eyes blank and a dumb smile plastered on his face. His crotch grew a painfully hard tent, and a small wet spot formed at the very tip.

Nick smiled in satisfaction, letting his diaper fall back down with a wet plop. His friend is back to being normal, and it's all thanks to his diaper! He noticed it has a calming effect on people, but it's never been so good before.

The cat was content to sit there for a while, and from Nick's shifting perspective that was all for the better. What little part of him still actively thought quite enjoyed the stench burned into his nostrils, continuing to flood his mind like a broken dam. He could hear his breathing and feel the moistness in his breath gather on the diaper before drooling back onto his lips. Or was that the ooze making its way through the plastic? It was hard to tell, and he didn't care enough to wonder.

Nick started to rock his groin against his new friend's face, shit and piss sloshing in his diaper and dribbling out the sides. They oozed down his leg, staining the tiger's clothes as they gathered. Todd felt something jabbing at him as the enveloping pillow of the diaper sloshed around him. A cock? A cock, his hazy mind confirmed. That only made his own swell more, and he felt the urge to suckle at it. He tried his best, but couldn't get at it through all the yards of filth separating him from it.

Todd's paws came up around Nick's sides, pushing up the leg holes and into the diaper itself. He moaned at the feeling of the semi-solid paste, squeezing it between his fingers and letting it soak deep into his soon to be ruined fur. All he could think of was cock, shit, piss, and his new friend. He never did stop trying to suck the cock, though what part of him could think knew that he couldn't. He may not have been intelligent at the moment but it doesn't take much to realize you can't go through solid things.

Finally, finally after maybe fifteen minutes of this, Nick lifted his diaper up again, burbling happily at his new friend. Todd's dazed smile turned into a needy frown, whimpers escaping his pouting lips as that diaper was taken from him. He needed it! He wanted it! Even so, Nick scooched his ass down Todd's body, leaving a second layer of ooze behind, and Todd eventually accepted the fact that his new favorite diaper was too far away to sniff and suck. Eventually the plastic mass of shit and piss came to rest over Todd's soaked tent in his pants, and the tiger began to grind back into it, staring blankly into Nick's eyes.

The cat was fully aware that his friend wasn't quite himself at the moment, but he had no moral code to tell him that what he was about to do was bad. He saw it happen in movies all the time and always wanted to try, so why not now? He wouldn't resist, unlike his mother, father, and everyone else he tried it on.

Nick slowly leaned forward, his slightly sour breath causing the tiger beneath him to wrinkle his nose. He could see his breath gather on the tiger's whiskers, tiny little droplets ready to fall. Closing his eyes, he pressed his lips against Todd's.

Nothing really happened.

Todd's smile faded into a blank look, and the two sat there for a few moments, lip to lip with equally blank stares. Nick was confused. Wasn't it supposed to be funner than this? The adults seemed to have a lot more fun when they did it.

The realization washed across him like the light from a dim bulb. Of course! Adults kinda, like, sucked on each other, didn't they? The cat began to giggle, letting his drool splash across the tiger's already soaked fur as he began to nip and suck at the other's lips, slurping loudly as he took the tiger's entire bottom lip and a bit of his chin into his mouth.

This roused the tiger just a bit, some semblance of consciousness fighting through the dull look in his eyes. He didn't understand exactly what was going on, just that he felt good, he felt wet, and... his friend was sucking on him. A smile again graced his face. He could do that too! He groaned as he began to suck on the cat back, pressing their lips together, sucking each other intermittently, sometimes even taking the other's entire snout into their mouth and just suckling, drool oozing and burbling everywhere.

The room filled with moans as they both began to get more into it, Todd's paws roaming the expanse of Nick's diaper, kneading the thick shit through it. Every time he pulled his hands back they were covered in thicker and slimier shit, but he didn't care, and rather liked it. It felt as nice as the warm drool dripping down his cheeks, around his head and into his ear. It matted his fur back, was thick and smelled foul, but to him it was the best thing ever.

Nick took a liking to Todd's upper snout, frequently wrapping his lips around the base and sucking hard. This sent Todd into a frenzy, squirming and moaning beneath the cat. He didn't know what to do, so his hands just flung around, gripping the carpet and his own sides intermittently.

They were so lost in their embrace it was no wonder neither of them noticed it happening. Neither noticed Todd's nose getting wetter and wetter each time Nick pulled back, a wet bubbling sound coming from his nostrils with each breath. Nick sucked harder and harder and longer and longer at Todd's nose, oblivious to anything else, and finally a quick slurping sound came from the tiger's nostrils. Both furs paused, staring at each other wide-eyed. What happened?

Nick pulled back one more time, mouth gaping open. A chunky green snot drooled from the back of the cat's gaping throat, slowly oozing across his tongue. The cat's eyes glazed over a bit and he began to shake, moaning and whimpering at the taste. It was so... good! He kept his maw wide open, a flood of drool dribbling onto the curious tiger's face. Todd leaned up a little bit, brows furrowed as he took a closer look.

Finally the snot reached the cat's sharp teeth, dripping onto Todd's lips. He instinctively licked it away, and his breath caught in his throat. It was amazing. Apparently Nick came to the same conclusion, plunging his friend's snout into his maw and suckling like he could think of nothing else. Todd melted, moaning, squirming, and shamelessly humping into the air, pulling Nick deeper and whimpering into his throat. Snot flowed from his nostrils like a sieve, and Nick alternated between gulping it down and pushing it down Todd's throat with his tongue, who eagerly accepted the gift.

The two remained locked in this gooey embrace for quite some time, continuing until the light from the sun setting through the window shining in Nick's eyes bothered him enough for him to stop, sit up and scoot down his tiger friend's body. Todd let out a plaintive whine, but despite his need the cat didn't return, instead leaning down and suckling on Todd's cock through his tented and soaked pants. Todd wasn't quite satisfied with just that, but realizing he wasn't going to get Nick to continue, he satied himself by simply rubbing the snot in his fur in deeper, slurping it off his fingers every so often.

With the influence of Nick's diaper and kisses so far removed from him, Todd slowly began to come to. His eyes focused again, the clouds dissipating in them, and he lay back, brows furrowed as he tried to work out what was going on.

He yelped as it finally hit him, jolting to his feet and sending Nick flying across the floor. He ignored the cat's grumpy yowl, feeling up his fur and face in panic. He was filthy! He had, he'd eaten his own snot, made out with... with that cat. He gagged at that thought more than he did the snot and his diaper worship. Why in the world did he ever want to do that?

His eyes caught the time, and his stomach dropped. Fifteen to seven! The tiger looked around the room in a panic, trying to figure out what to do. Nick's parents would be here in less than twenty minutes! He paced for a moment before rushing to Nick's side, who had forgotten his playtime with Todd already and was playing with toys. Ignoring the retard's whine, he pushed Nick onto his back, yanked off the diaper, cleaned the disgusting rear as best as he could, and quickly pushed him into a new diaper, loosely setting the tabs. It was Nick's parent's problem if it came off, as long as it was secure enough to see him off. After the diaper change, Todd barely had time to change out of his normal clothes and into his gym ones before Nick's parents opened the door.

He yelped as they came in, much to their confusion, deflecting all their questions as best as he could while trying to appear in control of himself. In reality he appeared terrible; his fur was greasy, clumped and all over the place, his eyes were wild and his smile was... strangely gooey. His voice stuttered and cracked, and he was quite eager to brush past them the second he could, leaving them with their child as he grabbed his things and ran home.

For the first time in a long time, he was glad to be there.
