Caution: this fanfiction contains stuffing and weight gain, so if you aren't into that, steer clear!

Torahiko Ooshima is a chubby chaser and loves to fatten up his friends, Tatsuki Midoriya and Juuichi Mikazuki, by indulging them in all sorts of snacks. One afternoon he makes a huge surplus of food for the two, and the aftermath puts them and their appetites to the test.

Torahiko Ooshima always loved cooking for his best friends, Tatsuki Midoriya and Juuichi Mikazuki. Tatsuki, an apprentice of his carpenter father, always went over to his best friend's house after a long day of work, and Juuichi was always finished with judo practice around the same time. Tora always made sure to keep his cupboards stocked with snacks and was always cooking something for the two boys by the time they got there.

He always had an immediate excuse whenever he was asked about all the food, the most common one being, "Well, I've been trying to practice my baking skills lately and I thought you two would be great taste-testers. Besides, I just want to give you guys a treat for being such good friends!" After a while, Tatsuki and Juuichi didn't pay much mind to it and considered it to simply be a tradition of theirs. Tora wasn't lying to them, though, the tiger truly loved to show how thankful he was for them and he loved being able to strengthen his cooking ability with them. But at the same time, he also had another reason for all the grub he made for the bear and dragon.

Simply put, he wanted to see them bigger. This had been going on for weeks now, and whether they were aware of it or not, the two were gaining quite a bit of weight from the constant stuffing. They already had a profound body size, both boys boasting sizable muscle-guts, but their daily gorging was undoubtedly making them much... softer. Torahiko admired how their bellies got rounder and rounder, their arms and thighs getting thicker and thicker, the seams and buttons on their clothes struggling more and more each day to hold their expanding physiques.

It was absolutely impossible for Juuichi's jacket to zip over his round sphere of a belly anymore (not that he ever zipped it anyways) and the bear's white tank-top now exposed a large section of his gargantuan gut. Tatsuki's tan work pants had obviously seen better days; the seams on the legs looked about to rip and his belt and pants button seemed visibly overstretched from holding the reptile's colossal stomach back. Torahiko anxiously awaited the day the dragon's pants would finally give way and burst open.

One sultry afternoon, Tora was hard at work preparing meals as usual, when he suddenly heard his best friends come in the door for their daily bout of snacks. Tatsuki grinned and yelled, "Hey Tora-kun! Whatcha got cookin' today for us?" while Juuichi simply nodded, giving his own silent greeting.

"You two sure are lucky today! I've got a big steak, a huge plate of cheeseburgers, and some curry for Tatsuki! For Juu, here's some chocolate cake, strawberry cheesecake, and double chocolate chip cookies!", Tora declared with excitement.

It was much more than he had normally served for them in one day and it all certainly looked delicious, the meat was well-marbled and juicy, the burgers were about as big as the dragon's fist and seemed almost too wide to hold between his two claws, and the curry was piled high with all sorts of spices and meats. The two cakes that were made for Juuichi were moist and thick with loads of frosting and the cookies were about as wide as the bear's hand, all of the meals slightly bigger than the plates they were on.

No sooner had the tiger set the gargantuan loads of food down, the two ran as fast as their bulky legs could carry them to the table and immediately started to dig in. Even Juu, as polite and calm as he normally was, couldn't help but succumb to his gluttony and immediately started to shovel mouthfuls of rich cake into his mouth.

Both of them had gotten much more accustomed to eating so much in one sitting, and as a result, their appetites had grown along with them, enabling them to eat more and more during each visit. Not to mention, they were practically eating themselves out of house and home as well, as Torahiko had often found them shopping at the local market to restock on grub much more often than they used to. They didn't seem exactly oblivious to it, making a humorous comment about it every once in a while, but they certainly didn't seem to mind it at all.

Tatsuki quickly tore into the steak and wolfed it down, savoring the meaty taste and texture. Well-done, exactly as he preferred it. Torahiko quickly learned the boys' preferences and always knew how to cook exactly to his friends' expectations. The meat was rough, The reptile disregarded the sudden tightening around his waistline and went on to the curry.

Meanwhile, Juuichi was still working on his chocolate cake and cookies. The bear loved his sweets and appreciated every second of indulging himself in the desserts. With each slice and each cookie he could feel the amount of inches around his belly increase, his clothes clinging to him tighter and tighter with each bite and his gut peeking out more and more from underneath his tank-top as it bulged outward further and further.

Despite being unable to breathe fire like in the myths, Tatsuki, being a natural-born dragon, always had an affinity for spicy foods, and curry was no exception. He picked up a spoon and piled the scorching-hot rice into his mouth, but his rapid consumption of the meal made him desperately want something to drink, which caught Torahiko's attention. The tiger poured him a glass of orange soda, which went down the reptile's throat almost instantaneously. As the carbonation rose in Tatsuki's gut, he let out a thunderous roar of a belch that felt almost satisfying to him.

"Heh, listen to the powerful roar of the almighty dragon!", he howled as a let loose a smaller but still just as noisy burp.

At the other side of the table, Juuichi felt like he was a single bite away from bursting, but the cheesecake was so delicious and fluffy that he couldn't bear to stop eating it. Besides, he was almost done anyways; why should he give up now? He gradually picked up a slice with his bare paws and swallowed it at once, working through the shocks of pain that went through his stuffed belly. The smooth, succulent combination of cream cheese and strawberries was almost enough to make the ursine completely forget about his aching gut. He picked up another slice, then another, until he finally finished it all.

The bear couldn't believe it; he ate two whole cakes and a big batch of cookies and it was now all packed in his massive, furry stomach. He let out a deafeningly loud belch and then looked away and blushed, embarrassed about his outburst. Underneath the shy exterior, however, he was loving every bit of feeling like a stuffed pig. His gut was now almost entirely exposed by his old tank-top, now covered in a few stains from the food.

Juuichi simply threw off the shirt and gently massaged his sore stomach, which now was sweating a bit from a combination of the hot afternoon and all the work from the eating he had done. The bear felt content, and he reclined in his chair while letting out a quiet sigh of bliss.

At the same time, Tatsuki had cleaned up his plate of curry and continued to his pile of burgers. There had to be about a dozen of them, all so mouthwateringly juicy and tender. The reptile grabbed one in each hand and took huge, greedy bites. With each burger he devoured, his pants fought to restrain his swollen belly with increasing difficulty. As he reached the sixth burger, he suddenly felt something tightly wrap around his gut: his belt, now desperately trying to hold on to his rotund figure. He paid no attention to that, though, he had burgers to finish up.

The dragon kept on eating and eating, until he heard a SNAP! He was completely shocked, he actually burst his belt buckle. The release of his leather restraint allowed his stomach to expand much more freely, giving him even more motivation to keep eating. Torahiko couldn't keep himself from staring, the sight of the duo's bloated bodies becoming too chubby for their clothes was a dream come true.

As Tatsuki swallowed the last of the burgers, he finally reached the limits of his pants button, which popped off with ease. The fly on his pants practically unzipped itself from the force of his gut, leaving his full belly to expand in his lap with all the new space. He was so comfortable, reclining in his seat to take in the warmth of the summer afternoon, his unrestrained gut slouched in his lap. He couldn't help but release another raucous belch as he let the food in his stomach digest. Torahiko was feeling ecstatic that he had fed them so well, and the bear and dragon were in literal paradise.

The room was in a state of peaceful silence for a while before Tatsuki asked, "Well, thanks, Tora-kun! That really hit the spot! But, uh, you wouldn't mind rubbing my aching belly, would you?"
