Chapter Text
“It looks as though I’ve caught a Phantom Thief,” Akechi said with a smirk as Joker struggled futilely in his seat. With his hands tied behind him to the back of the chair, the raven-haired boy wasn’t going anywhere. “Though, you did make it rather easy. You were just too tempted to resist, weren’t you?”
He picked a heavy bag up off the table and waved it under Joker’s nose, amused by how his rival scoffed and turned his head aside. As though he could hide his interest. “Don’t be so coy. We both know you’re a glutton. How else could you get so fat?” he asked. Joker had been divested of his coat, and the rope holding him in the chair sat underneath his fat moobs, propping them up and making it very obvious how flabby they were in the thin vest he wore. Akechi cupped one in his left hand, then smacked the great beast of a belly beneath it, which was already pushing up the hem of Joker’s vest just from sitting down. He’d outgrown it again. Akechi didn’t really mind that, but it did ruin the illusion somewhat, and he shifted focus back to Joker’s defiantly set chins. “Well, since you’ve traded your freedom for these, I suppose it’s only right I let you eat all of them, isn’t it?”
The look in Joker’s eyes was full of both eagerness and trepidation as he looked at the bag. “All of them?”
“Ten Big Bang Burgers,” Akechi said as he took each burger out of the bag, placing them in a row for his captive to take in the feast he was about to be subjected to. “I hope that’s enough for your great gut. Or might it be too much? No, that couldn’t possibly be. Well, if it is, you know how to beg for mercy, don’t you?”
“Just get on with it,” Joker told him, but the look in his eyes was certain. Good. He remembered the safe word.
“Being so defiant will only ruin you in the end,” Akechi said lightly, shucking the wrapper off of the first burger. “Well, then…bon appetit.”
Joker resisted a small bit, but it didn’t take long for him to open his mouth and let Akechi cram the burger into his mouth. After all, this was just a play, an amusement for both of them. Outside of token resistance, he ate the first burger quickly, with the second soon following. That would have been quite grease enough for the whole day for Akechi, personally, but for Joker, it was an average meal. He was such a well-trained hog that he even gave a small groan of pleasure as Akechi forced the third burger into his mouth. His chewing started to slow, though, and Akechi put down the half-eaten burger, picking up the first soda from the six-pack he’d picked up from the konbini. Joker was still taking his sweet time swallowing down the burger in his mouth as Akechi pressed the bottle to his lips, but he got the hint. Soon enough, he gulped and opened his mouth, letting Akechi drain the bottle into his mouth as he chugged the sweet liquid. His chubby cheeks puffed out afterward as he tried to hold in a burp, but with all the carbonation in him, the sound still erupted from him loud and clear. Akechi palmed the roll under Joker’s belly button, curled his fingers around the thick underhang before pressing on it to prompt more burps from his prize pig. Joker might be a daring thief in the “Metaverse” and his true nature that of a glutton, but he tried hard to pass himself off as a polite young man in day-to-day life, and Akechi could see those plump cheeks starting to pink.
“Are you embarrassed?” Akechi asked. “There’s no need. It’s just you and me…though, honestly, it’s too late to hide what a piggy you are. Your pants are so tight, I’m amazed you haven’t broken them. They must be a very durable brand.”
“They are…” Joker broke character a bit as he shifted slightly, the leather of those same pants creaking. “Can you open them?”
Akechi reached under Joker’s gut again, thumbing the button at the waistband and then giving that same waistband a light tug. Joker’s fat gut wobbled with the motion. “Hmmm… I don’t see a need to,” Akechi said with a smile, staying in character. If it were really painful, Joker would make it clear. Discomfort, though–well, Akechi liked seeing him squirm a little. “You’ve made such an excellent start of eating yourself out of them, I’d like you to finish the job.” And he picked up the half-eaten burger again, ready to make his boyfriend eat more.
Joker took longer than Akechi had expected to break free of his pants. Not for lack of trying: refreshed from his drink, he gobbled the remains of the third burger eagerly and set a steady pace as he started his fourth. And Akechi helped by hiking the waistband up as high as possible, making sure it was pulled taut around every bit of blubber. But Joker’s occasional grunts were becoming more vexed, and he kept fidgeting, breathing in deep while chewing to expand his belly, flexing his legs as though he were hoping to stretch the fabric thin or something.
Which he did. Months of being rubbed between two thundering thighs meant the inner seam was quite worn, tearing it up and down the entire length of his right leg in one movement. Joker looked both relieved and annoyed as it came apart, and Akechi chuckled as he placed a hand on the inside of the meaty thigh, rubbing his thumb over the plump flesh, momentarily reddened from friction.
“Not quite your intended goal, was it?” he murmured. "But you’re getting so big. I’m certain if you keep going, you’ll burst from these pant’s confines completely. Unless, of course, you burst yourself first.“
"I’m nowhere near my limit,” Joker huffed irritably.
“That’s what I like to hear.” And it was true that Joker had quite the appetite. How else would he have put all the pounds of soft fat on himself so quickly? Akechi certainly contributed, yes, taking Joker to restaurants, and stuffing his gluttonous pig in amusements like this, but all it had taken was the gift of a cooking class for Joker to start plumping himself up. As soon as he was taught the basics, Joker went wild with recipes for rich, heavy comfort foods…even though he made sure to cook healthier selections for Akechi, the once detective had occasionally found his own clothes becoming tight with a few extra kilos, having to suck in his belly to button his trousers before he reined in his diet. Joker had a gift for anything he put his mind to, including cooking. It could be vexing at times. If Akechi allowed himself to eat as much as he wanted of Joker’s cooking, well, he probably wouldn’t have half the gut or ass Joker had, one big enough to sag over the captive’s upper thighs, and the other overflowing the chair he was tied to, but even half that would still be much fatter than Akechi wanted to be. Even if he was no longer in the public eye, hadn’t been for quite some time, he still had that impulse to make himself perfect in presentation. (Though sometimes, he had the urge to–to tell Joker to try to make him fat, and then see–if he’d notice extra butter and oil in his food or slightly bigger servings, or if he’d excuse the first five kilos as winter weight–if it were a competition between the two of them, if he could entice Joker to try to wreck his figure, how fat would he get before his better judgment kicked in and he called the game to a halt? But that was a temptation he had yet to act on.)
Joker had never had the same compulsions about appearance, as was obvious by the obese figure he’d let himself bloat into. And by the mess he was letting Akechi make on his face, ketchup and crumbs splashed on the normally neat eater’s face. But while Joker allowed himself to get dirty, he didn’t actually enjoy it. Neither did Akechi, as much as he loved the activity that led to the mess–stuffing his boyfriend fatter and fatter. After Joker finished his fifth burger, Akechi used his thumb to push some crumbs back toward Joker’s lips so he could eat them. "Mustn’t waste calories.“ What wasn’t easily cleaned up that way was wiped up with a napkin.
Joker’s breathing was growing heavier with his fullness, large sighs chasing burps that were becoming more and more frequent as he grew too stuffed to attempt stifling them. His eyes started glazing over on the seventh burger, and Akechi stopped pushing the food at him but held it steady, rubbing circles into his hog’s gut to try to ease all the gas out. Joker burped quietly four times. The fifth was long, and loud, and he looked a bit flustered after it, as though he’d surprised himself, but his eyes were alert again, and that was a good enough signal for Akechi to resume. Joker’s chewing was becoming mechanical now, but he still wanted to eat. A true glutton.
His pants finally gave up the ghost midway through the eighth burger, the button pinging against Akechi’s thigh before skittering away. Joker’s pants immediately unzipped themselves, the waistband crumpling under two rolls of fat breaking free.
Joker let out a sigh of relief. Akechi smirked. "So you did manage to eat yourself out of them,” he said. "But you’re not done yet."
Two more burgers, and one more bottle of soda from the six-pack. One of the biggest downsides of how fat Joker had grown was that stuffing him didn’t make the same dramatic difference in his physique as it had roughly two years and a hundred kilos ago, but Akechi’s trained eye could pick out the swell, and his hand on Joker’s gut could feel the stuffed firmness beneath all the soft flab. Plus, Joker’s shallow breaths made it clear he felt like a beached whale. Even after Akechi untied his hands, he made no move to get up. "Do you want me to rub your stomach?” Akechi asked.
“Please.”
“Then waddle your way to bed. I’ll take care of you there.”
Oh, he knew Joker would likely fall asleep on him once they were in bed. If they did have any sex, Akechi would be doing all the work, as becoming so fat had lowered Joker’s stamina even when he wasn’t stuffed like a turkey. But Akechi rather enjoyed that, just as he enjoyed how laboriously Joker hefted himself to stand before placing a hand on his overfull stomach and trundling to bed that way, his plump love handles jiggling in waves above his ruined pants. Joker might have fattened up a bit on his own, given his inner glutton, but the fact that his gut split into rolls, that his walk had widened with his thighs pushing each other apart–Akechi took great pride in that. He’d helped a piglet turn into a hog.
