“Time’s up. Everyone drop your tests off on your way out of class.”

Amid the shuffling of papers, a snickering voice called out: “Why don’t you come get them yourself, sir?”

The gray wolf glared at the young fox, but said nothing in reply. Teaching ninth-graders meant that he had some of the most precocious children in the district, full of boundary-pushing little smart-asses, but he knew he made it easy for them. He’d been steadily putting on weight through his thirties - more than he cared to admit - and had reached a point where he really needed to take action about it. He couldn’t even fit through the aisles in his classroom anymore. Even the walk from his car to his classroom was tiring. 

He needed to do something about it, though he could never quite seem to muster up the motivation. And while his adult co-workers had enough tact to avoid the issue, the 14-year-olds in his class did not. Especially Aiden, the young red fox that had teased him out loud. Though the boy was smaller than most in his class, he more than made up for that in both intelligence and wit. He was a sly fox, through and through.

It was best not to engage. The class shuffled out slowly, dropping their papers in a pile on his desk. Aiden was the last one to leave, bookbag slung over his shoulder and tail swaying behind him. The top button of his shirt was undone and his tie was loose, and he still had a little smirk on his face. “That was easy.”

The foxboy’s attitude was annoying, but something about his casual, youthful cockiness was alluring to the wolf. He tried his best to shove those thoughts down - letting those kinds of fantasies linger in his mind was dangerous for a teacher. He cleared his throat. “We’ll see. I could give you detention for those dress-code violations, Aiden. Tighten up your tie.”

The fox put his paper on the top of the stack.”What, you can’t get enough of me in class, Mr. Miller? You want to see me in detention too?”

His teacher grumbled. “Just.. get to your next class.”

Aiden grinned and swayed out. The small fox lingered at the door for a moment, looking back at the large wolf before disappearing into the busy hallway. “Grade mine first. I’m pretty sure I got everything right.”

He had third period free, but he was too flustered to head to the teacher’s lounge. And, as he readjusted himself himself in the chair he’d outgrown, feeling how his belly occupied most of his lap and the space between his thighs, how tight his already-very-plus-sized cardigan had grown around his middle, he couldn’t muster the motivation to pull himself out of his chair. 

He also, as he reached into his drawer, couldn’t wait another hour and a half for lunch. He pulled the top sheet off the stack and began to grade it, as he bit into the first of four sandwiches he’d packed for himself. 

As he predicted, the boy had gotten full marks. He scribbed an A+ at the top of the page, annoyed at having to reward the sly fox for his good work. It was only when he flipped the test over that he saw the boy had written something on the back.

after school, behind the gym. if you dare ♥ 

The wolf’s face blanched when reading that, and all those repressed thoughts came to the surface. Behind the gym is where all the troublemakers did troublemaker things - was Aiden really..? No, it was impossible. He was barely a teen, and the wolf was two and a half times his age - and four times his weight. 

He shook his head and, with trembling paws, grabbed the next paper to grade. “Don’t think about it,” he muttered to himself, eating more quickly to distract himself. “Ignore it. He’s just making trouble.”

But he couldn’t forget it.

***

The last schoolbell had rang fifteen minutes ago when Mr. Miller rounded the corner behind the school gym. Grass grew through cracks in the concrete here. Two older students were making out against the brick wall, another group was playing some kind of gambling game on the ground. 

“You’re not supposed to be back here!” the wolf bellowed as he rounded the corner. “Scram!”

The groups immediately broke up, with some nervous freshman running off in all different directions. He hadn’t seen Aiden among the crowd, but after all the others had dispersed, the fox remained. He was leaning back against the brick wall, backpack at his feet. In his left paw was a lit cigarette. He looked over at his teacher with a grin, but did not move.

Flushed, Mr. Miller waddled over to him. His voice was softer. “You’re too young to be smoking, Aiden. Put it out.”

“Why?” The fox took a deep drag and exhaled slowly. “Everyone knows you smoke too, Mr. Miller.” 

It was true. The wolf’s vices had been piling up, and he couldn’t seem to keep any of them under control. “It’s different.”

“You’re right,” the boy grinned. “The difference is that I can limit myself to one a day, and let myself enjoy it. Meanwhile, you can’t stop yourself from chaining half a pack after lunch. Hiding out back, trying not to let anyone see.” He giggled a little. “As if anyone could miss you.”

The teacher’s face turned red. “You shouldn’t speak to your teachers like that, Aiden. It’s rude.”

“Oh, is it?” The boy stepped forward. The tips of his ears barely came to the wolf’s chest, he couldn’t have been over five-feet. He put one of his paws on the wolf’s sweater-clad belly. “Even ones that have a crush on their underage students?”

Mr. Miller stepped back. “I- I- don’t know what you’re insinuating, Aiden, but..”

“You got my message, Mr. Miller. I knew you wouldn’t be able to resist.” He took another drag from his cigarette, mischief in his eyes. “Just like you can’t keep your eyes off my butt in my class. You’ve got no self-control. I mean, look at how fat you are!” He laughed. “You can’t say no to anyyyything, can you? It’s a little pathetic, honestly.”

The wolf’s feet were locked in place. Was he really so transparent? “A-a lot of people are overweight, Aiden. It’s not nice to..”

The fox waved that off. “You aren’t most people, sir. You’re a wreck. I can’t even imagine what it must be like to be you. Waking up worse every day. Never working out. Eating all junk food.” He giggled. “Then thinking about your fourteen-year-old boy students when you paw yourself off. Thinking about, well - me. Don’t tell my friends, but I’m a little into it too, Mr. Miller. It’s almost cute what a lost cause you are.” 

The blood may have rushed to his head, but the wolf’s arousal was piqued now as well. It scared him how blunt and forward Aiden was being; scared he might actually act on his impulses. “I think I should go..”

“Nonsense, Mr. Miller.” He stubbed out what was left of his smoke on the ground, then grabbed the front of the wolf’s sweater. “Come, follow me. Don’t worry, I’ll go slow.”

He couldn’t resist. Aiden led him through the empty gym. “I know you’ve never seen one of these before, Mr. Miller. This is where people who care about themselves exercise.”

Into the locker room they went after that. Though it was after school, there were still a few students changing. They stared at the boy and the overfed, out of shape teacher following behind him. The teacher had no idea where Aiden was leading him until they stopped at the back of the locker room, before a great big scale. 

“Time to undress, Mr. Miller. I want to see what I’m working with.”

“Aiden! No! That’s inappropriate!”

“Aw, are you embarrassed? I’ll go first, if that helps you feel better.”

Before the teacher could say anything, the young fox had pulled off his tie and untucked his shirt. The wolf’s protestations disappeared as he was treated to first view he ever had of Aiden’s bare body. Though he’d always thought of the boy as a scrawny thing, there was quite a bit of muscle on his pubescent body. His stomach was firm and chest defined when he pulled off his shirt, and as he wiggled his pants down to the ground and stepped onto the scale in nothing but socks and briefs, the teacher could not keep his eyes off how cute and round the fox’s behind was. The scale barely ticked a quarter of the way around.

“87 pounds. See, that’s not so hard. Your turn, Mr. Miller.”

“I-I don’t..”

“Aw, c’mon, Mr. Miller. Don’t you wanna play with your favorite student?” Still in just his underwear, Aiden began to untuck his teacher’s shirt. “Let me see.”

“Aiden, there are people in here!” He could hear the panic in his voice. “Fine, I’ll do it!”

The foxboy smirked and stepped back. Mr. Miller looked around for anyone watching, then pulled off his sweater. His belly had grown so fat that it was difficult to untuck his shirt, and when he did, he could feel all of his unconstrained blubber wobble and slosh out.  His oversized slacks dropped to the floor, and he stepped onto the scale in naught but his plaid, skin-tight boxers. He’d never felt so fat in his life.

The scale ticked all of the way around the enormous dial, eventually landing on exactly the same number: 87. Aiden began to laugh embarrassingly hard. “Look, Mr. Miller!! We’re the same weight after all!!”

The wolf’s face was bright red now. “It’s not that funny.”

“Oh,” the teen fox giggled. “I think it is!! Now, I know you don’t teach math, so I can help you out with the numbers. Once around is 400 pounds, and since it kept going PAST that number and landed on 87, do you think you can figure out how fat you are?” His paws once again went to his teacher’s spilling midsection, grabbing his soft bellyroll with two small paws to wobble it.

“487? I.. I had no idea, I..”

“Aw, didn’t you, Mr. Miller? Didn’t you see how badly you were letting yourself go? It’s all we’re talking about in class. Everyone is so shocked and disgusted by how embarrassingly fat you’re getting. You’re so out of shape, you sweat just passing out papers! Jason was lowkey grossed out when you gave him his paper back last week, there were chocolate smears on it!!” 

Aiden was giggling to himself now, but his briefs were tented. With the fox in front of him, Mr. Miller couldn’t stuff his attraction to a boy this dangerously young, adorable and small. It was the only reason he stood in place while he was teased and mocked by his fourteen-year-old student

Instead, he remained blushing. “If you think I’m so gross, why you’d send me that note then? Just to tease me? The fat teacher almost three times your age?”

“Oh, Mr. Miller. I do like teasing you, but that’s not it. I just, well..” Aiden’s cheeks reddened for the first time since the wolf had known him. “..watching what a wreck you are, it does something to me. Watching you ruin your body for a handful of sweets. Shorten your life chain-smoking cigarettes, hoping no one can see how out of control you are. Risk going to jail to meet up with me. You’ve got no self-control at all, Mr. Miller. 

“I wake up at 6am every morning. I work out every day. I watch what I eat, I do well on tests. I care about my future. You don’t. You’re my teacher, a real adult, and you’re so pathetic. Eating yourself even worse every day. Sloppy fat rolls sagging out of your shirt. Butt so fat it can’t fit into a chair. Meanwhile, I’m doing squats three times a weak till my quads ache. You’ve never done anything but sit on your butt and wheeze and eat, Mr. Miller.”

His small paws ran down his slim, tight middle, over his white-furred abs. “Look at this, compared to the slop that’s sagging off your waistline. You want it so bad, even though you’re too weak and fat to ever get anything close to a body like this.” The boy turned around and leaned against a row of lockers, arching his back and sticking his behind out. His hips swayed slowly, leading his fuzzy tail. His small briefs were sheer enough that his teacher could see where the white stripe of fur between his cheeks faded to orange on either side. “My butt - the one that I know you can’t stop staring at - is cute, isn’t it? All my hard work, Mr. Miller. Hard work you’ve never done a day of in your lazy life. Compared to the wobbling pillows of lard that swallow up your desk chair.”

Aiden kept leaning against the wall. “You do want it, don’t you, Mr. Miller? You want to fuck me?”

Even though it was mostly buried between his chunky thighrolls, the fat wolf was beyond turned on.  The words felt like they were being pulled out of him against his will. “Yes.”

“Pervert. Follow me.”

Both in their underwear, Aiden walked into a supply room toward the back of the gym. The teacher followed behind him, despite every voice in his head telling him to turn around. The foxboy pushed open the door to a room where extra gym equipment was stored, and he locked it behind them. “It’s just you and me now, Mr. Miller. Get naked. Let me see how embarrassingly huge and fat you’ve gotten.”

There were a few gym mats on the wooden floor. The wolf stripped slowly, tugging skin-tight boxers down to the floor. The cellulite on his belly sagged halfway down his thighs, smothering where his dick used to be. He stood there for a long moment as the little fox stared at him, an increasingly malicious smile tugging at the corners of his sly mouth. “How do you even look at yourself in the mirror every morning, sir? What’s it like not having a dick anymore?”

Aiden tugged his briefs down next, and while his cock wasn’t very large - four inches, maybe - it stood out hard and proud from his athletic frame. “It’s bigger than yours. Maybe I should be the one on top, sir. What do you think about that?”

The wolf only whined in response, making the fox grin again. “Lay down on the mat. Belly up. Let me see if I can’t find that dick of yours.”

The cocky teen had full control now. The teacher did as he was told, slowly getting onto the mat and then laying down. His belly obscured his vision from this angle, and his double chin and chest made it hard to breathe well. Still, he could watch as Aiden walked around him, his small body towering over him from this angle, with a very good view of the fox’s ballsac and rump from below. He circled the wolf for a long moment, smirking down at the pathetic beast, before kneeling before his belly and pushing back a lot of fat. 

The boy’s arms were cool against his sweaty blubber. “I think I can see it. Maybe not as buried as I thought that it was. You’ve got like a whole inch here, Mr. Miller. Are you proud of how little you have left? Not that it’ll last much longer, not the way you’re going.” 

“Aiden, I.. ahh-wooo!!” His whimpering turned into a little howl that made Aiden giggle. “Aw, what a pathetic little noise - like you’re trying to be a real wolf, still. Do you like how that feels, Mr. Miller? Has anyone ever even touched this worthless little thing of yours before? Or are you only interested in young boys?”

When his teacher only whined, Aiden squeezed. “Beg for it, Mr. Miller. Beg me good enough and I’ll ride your fat little inch until it spurts all over my perfect butt.”

He had no choice. “P..please, Aiden - please, it feels so good, I need it from you..”

“You’re pathetic, Mr. Miller. Say that. You’re getting fatter. You’re smoking more. You’re getting worse. Your rolls sag deeper every day. You fuck your barely-teenage students.”

“I’m pathetic. I’m.. I’m unsaveable. Please, please, please, I need your perfect butt Aiden, please make me cum!”

“Disgusting.” The fox straddled his teacher’s hips, arms around all that belly as his hot little tailhole grazed the slick tip of his teacher’s desperate dick. “How does that feel?”

“P-please, sit on it!!”

“Do one more thing for me, first. Mr Miller.”

“Anything!!”

Orange paws came out of nowhere and shoved something into his mouth - something that tasted like butter. “Swallow.”

The teacher groaned as he obeyed. It was butter. Room temperature, slick and greasy - the conniving boy had probably stored it here earlier. Another mouthful of butter, then another. He swallowed it, feeling more gross with every bite. “So fucking disgusting.”

The wolf was about to push back when Aiden finally slid down onto his chubby cock. He felt his width stretch the fox’s hot hole, heard his little whimper when it entered him. Mr. Miller’s brain shut off with pleasure at the feel of being inside his student, finally getting permission to fuck the teen that clearly wanted him worse.

He swallowed the next stick of butter, alternating emotions of disgust and pleasure, feeling his useless fat rolls wobble against Aiden’s tight abs, his thighfat against the boy’s tight rump. “Eat it, Mr. Miller. It’s so hot watching you get worse!! I want ruin every part of your life. I want to wreck your body and your health and your job and your friends. I want you to be a housebound shut-in grinding in your own fat to thoughts of the hot boys you disgust. Eat and get worse for me and I’ll let you cum. Keep going, Mr. Miller!”

The wolf could barely see anything but the paws feeding him, but the fox’s butt felt so amazing. Aiden’s dick slid between his abs and the wolf’s belly as he stuffed him. His words were humiliating in the extreme. He’d never felt so useless and little, but he’d endure anything just to cum. Including having two pounds of butter smooshed into his mouth.

“By the end of the school year, you’re going to be sooo fucking pathetic and useless, sir! Sloppy fat spilling out everywhere as you barely even breathe. You can’t stop!! You’ve already ruined your body so badly, and you still can’t stop!! How much worse can you get??” Aiden’s breath came quickly as he rode his teacher’s dick faster. The boy easily took an inch or two of chubby adult cock. “Begging me to ride your dick when you’re so unhealthy you can’t even get hard anymore!! You’re going to be as good at begging as you are at eating, Mr. Miller! Ahh!”

Aiden’s tailhole clenched tightly on his teacher’s dick as he came, huge spurts of pearlescent white cum shooting high up into the air and drenching the wolf’s belly, face and chest. With zero stamina, the wolf was right behind, squirting a small, desperate load into the fox’s tight ass.

They were both breathing heavy after that, and Aiden rolled off after a moment. “Lucky your knot is sunk into all that fat so I don’t have to stay tied to you while you sweat and gasp and doordash McDonald’s or some shit.”

The wolf panted for a while before responding. “You can’t tell anyone..”

“Well,” the fox said, as he began to stand up, leaving the cum-soaked fat wolf on the mat. “I could. But then I’d have to admit that I fucked the fattest, most unhealthy teacher in school. That’s so embarrassing.”

Aiden pulled his briefs back up before pulling the pack of cigarettes out from his back pocket. He took one out and lit it.

The teacher couldn’t resist a little jab after so much abuse. “I thought you said you had self-control. One a day.”

The fox leaned down and blew a cloud of smoke into the wolf’s face, which made him cough, before putting the smoke into his teacher’s muzzle. “It’s not for me, sir. It’s for you. Finish the rest of the pack before you leave. I know you must be craving one, anyway - have fifteen.” He tugged his pants back up. “You know, if you ever want to feel my butt again.”

Mr. Miller inhaled deep, the nicotine hitting his brain in moments. “I can’t do this again, Aiden. It’s.. It’s bad. Really bad.”

“But Mr. Miller - all you do is make bad choices.” The fox finished getting dressed and moved to open the door; the wolf was still nude and covered in cum, face slick with butter and gasping for air. “Snap me when you hit 500.”

The door closed behind him, and the fat wolf inhaled again, watching the silky smoke billow up toward the ceiling. “Fucking ninth graders.”
