Summary: Fatgum corners a sludge villain in an alley. Desperate, the sludge villain decides that his only way out is to ride Fatgum out of there like a cab by hiding in his stomach. Too bad for him - Fatgum is the Hero who fights with his fat! He knows how to handle his own stomach and, well, he's got a thing for feeling full too 

This is a commission! 

-

Just his luck that a villain would appear before he was able to restore his fat, and right while he was in the middle of enjoying a delicious meal too! Speeding down the alleys, grateful that his slimmer shape at least allowed him to dart around the sharp corners and slip through the narrow lanes, Fatgum chomped down on takoyaki as fast as he dared. Part of being a Hero who relied so heavily on his fat was knowing how to eat and run, though even he was pushing his ability with how quickly he was eating. Unfortunately, this meager snack wasn’t going to do much of anything. Not to mention, any calories he was swallowing down were being burned away as he chased after the villain. It was an ugly thing – nothing more than a large puddle of greenish sludge slithering at startling speed along the concrete. A warning had come over the radio a few minutes prior, letting him know that the villain’s primary method of attack was to stuff itself into victims’ mouths and suffocate them. It was vital to keep his mouth and nose covered before approaching the villain. Problem was, the best he could do was just use his hand. Even as he was closing in, using his arbitrary knowledge of the area to, hopefully, push the villain into a corner, he knew he was underprepared and vulnerable. 

Still, he couldn’t let that stop him! The villain had already hurt too many people. He was just going to have to figure out something to take him into custody. Ahead of him, the villain made a sharp turn into an adjacent alley. A wide grin spread across Fatgum’s face. He might not know much about this area but he knew that particularly alley. Looking down at it, no one could be blamed for thinking it was a standard alley that continued to weave behind the bustling main streets but this one held a secret. At the end was a wide left turn that led directly to a dead end. If there had been a fence or a low wall, the villain might’ve still stood a chance of getting away. Too bad for him – this alley was the definition of a dead end. It led straight to the back of an apartment complex. Only way out was to turn around and go back the way he’d come in. 

“Nowhere to run.” Fatgum murmured, his grin stretching even wider. He didn’t have a plan but he wouldn’t let that stop him! He would just have to figure this out as he went. 

Turning down the alley, he braced himself for the inevitable encounter. There was no other intel on this villain other than his preferred method of attack. Weak points, disposition and other factors that would help him handle these were factors he was going to have to interpret during the encounter – never a good position to be in. Flinging himself around the next corner, Fatgum skidded to a halt. So far, this was playing out exactly as he expected. The villain was trapped – he was clinging to the back wall of the apartment building in a position that seemed to suggest he was trying to climb up but was making no progress. It was an ugly thing – made him wonder if this was his natural shape or could he transform himself to look more like a human. His size wasn’t helping in making him look less scary either – asshole was much bigger than Fatgum originally thought. The slithering mass of sludge in front of him would probably fill up to the brim two standard size bathtubs. This world of quirks they lived in could produce some freaks of nature. Clearing his throat, Fatgum stepped forward. 

Bulging eyes swung around to stare at him. There was brief moment of stillness then the villain was moving, detaching himself from the wall and hurtling at Fatgum. A tentacle of sludge shot out, aiming for his mouth but he saw the move coming a mile away. Deftly jumping out of the way, Fatgum slammed the tip of his foot directly between the villain’s eyes. The villain split in half with a loud, wet squelch. Bellowing loudly, the villain slithered backwards, his bulging eyes rolling wildly. Some of his body clung to Fatgum’s boot, wriggling and writhing in a way that made his stomach clench in disgust. He gave his leg a hard shake, sending the remnants flying across the concrete. 

“Bastard!” The villain screamed, his sludge body rippling and wriggling, “Get out of my way!”

“Not a chance!” Fatgum laughed, dodging another tentacle’s attempt to get at his mouth, “Can’t have a villain like you roaming the streets free so make this easy for yourself and surrender peacefully.”

“The hell to that!” The villain retracted his tentacle. His oddly floating mouth, which never seemed to stay in one place, spread open in a large, snarling grin, “If I can’t get out here by getting past you then I’ll use your body as my own personal vehicle to freedom!”

“Huh? What kind of stupid shit are you-?!” 

In hindsight…he hadn’t been as careful as he should’ve been. He’d seen how fast that damn villain could move but had made the mistake in thinking that he was restricted to moving along a flat surface. Asshole didn’t have legs so it wouldn’t have crossed his mind that the villain could fling his entire body at high speeds across a short distance. The villain coiled itself back and, using some method that Fatgum couldn’t catch but later assumed utilized the tentacles he was able to produce, shot himself forward and up, smashing directly into Fatgum’s face. Surprisingly, it didn’t hurt, despite the speed they collided at. What did hurt was him slamming into the concrete as the impact sent him flying backwards. Caught off guard by the sudden attack, Fatgum couldn’t stop himself in time from opening his mouth to let out a sharp grunt. His fatal mistake quickly began apparently when two small tentacles of sludge wriggled into his stupidly gawking mouth – one clamped down on his tongue, the other on the roof, holding it open as a much bigger tendril shoved its way between his stretched open lips. A gurgling yelp was all he was able to get out before the mass began to wriggle down his throat. 

Fatgum’s eyes bulged. Bad! This was bad! He was trapped underneath the weight of this damn asshole! His arms were pinned to the ground. When he tried to use his feet to push himself up, sludge tentacles slithered down to squeeze his legs together. Cold panic began to pulse in the center of his chest. His heart was racing at a breakneck speed. If he didn’t do something soon to get the villain off him, he was going to suffocate…only…Fatgum blinked…breathe…he could breathe, not very well but he could still breathe. The villain was leaving just enough space for him to suck air in, though it felt like he was breathing through a straw. With a jolt, Fatgum realized that while he had been so distracted with trying to get free, the tentacle of sludge was quickly inching down his throat. This…this wasn’t part of his MO! All of his victims only had their mouths filled with sludge. There hadn’t been any evidence that he filled their throats to. What…what the fuck was it doing?! 

There came a rusty laugh from all around him, followed by the villain’s body shuddering, “Told you, didn’t I? I’m gonna ride you like my own personal chauffer outta here. Everybody is looking for me but they won’t think to look inside you. You’ve got just the quirk I need to make an escape so be a good boy and swallow down every inch of me. I know your belly can take everything. Don’t worry, I’ll only stay long enough to get myself outta here. When we’re safely away, I’ll make you puke me up. Hell, if you don’t cause me any trouble, I might even let you live.”

The villain laughed again. Fatgum blinked. The tentacle of sludge was far enough down that he could feel it in his chest. Despite looking disgusting, he didn’t taste as bad as he thought. Fatgum had certainly put more awful tasting things in his mouth. Exhaling slowly through his nose, he forced himself to relax back into the concrete. Okay…so that…that was the situation. Certainly a first for him. So, the bastard wasn’t planning on killing him…just using his body like some kind of weird pony ride. The tentacle was getting closer to reaching his stomach. The panic pulsing in his chest began to subside. Making any attempt to get free might result in the villain changing his mind. This…he could work with this. He was already beginning to formulate a plan when the sludge hit his stomach. It was the weirdest sensation but there was something about it that felt oddly…good. Thick, heavy fluid flooded into his stomach. He wasn’t too sure what did it but the moment the villain’s sludge was in his belly, he started to move more quickly, pouring copious amounts of his body down Fatgum’s throat. With moments, his stomach started to swell as it began engorged with the sludge. A hard twitch raced through Fatgum’s body. He moaned quietly around the seemingly never ending torrent of slippery sludge. 

Fuck…what…what was this? He thought that this would be nothing but unpleasant – just something he’d have to grit his teeth and bear in order to bring the villain in – but the more of his body that he brutally shoved inside of him, the more Fatgum had to recognize that this…it felt…it felt…incredible…He had always been a little bit aroused by the sensation of being full and this…this was a level of it that he didn’t know was possible. The pressure, the weight, the heaviness…ah fuck…fuck, he…he was getting hard! Boiling pleasure bubbled away in his crotch. Blood thundered straight down to his cock, causing it to stiffen and raise. Tingling heat coated every inch of his skin. Sweat started accumulating under his arms and between his restrained legs. If the villain noticed his arousal, he didn’t say anything. All of his focus seemed to be on getting himself inside of Fatgum. It was a little hard to tell over the golden haze that was beginning to dominate his mind but he was fairly certain that the villain was getting smaller. Made sense, considering how big his stomach was becoming. Ah…fuck, fuck, it felt so fucking good-! He thought he had fully understood the definition of full before but this…this was just making him realize that he had no idea what full truly was! 

This…this was full…he was being stuffed to his breaking point. His cock twitched hard against the constraints of his pants. He could feel a large wet spot growing where the tip was meeting his underwear. Fuck…he might cum just from this. More and more of the villain’s body pummeled down his throat. The weight of his stomach pressing down on him was nothing short of ecstasy. There was no need for the tentacles to hold his mouth open any longer. He was keeping it stretched wide to take in every last drop. Vibrant heat pulsed in his face. His large body was trembling. What blood was making his cock thrum and ache in his pants roared in his ears. He could distantly feel how small the villain was becoming. There was nothing holding his legs together but he didn’t think about running. Whatever was left of the villain was still covering his face, obscuring his sight.  It was a little disappointing…though, he wasn’t sure if he could take much more. His stomach…fuck, he was so full, he might burst! The thought sent a wild trill of excitement rolling through him. Fuck…he could seriously get addicted to this. 

“Almost there!” A tiny voice said. It took him a moment to register that it was the villain’s. “Such a good boy, taking in all of me! Now, swallow this last little bit then get me out of here!”

‘Yes…’ Fatgum thought hazily, stretching his mouth open even wider. The last remaining part of the villain that was outside of his body slithered down his face, pooling inside of his mouth. He started rapidly slithering down his throat, heading straight for his stomach. It was only when Fatgum felt him finally reunite with the rest of his body that he closed his mouth. Panting heavily, sweat running down his face, Fatgum slowly grinned. Full…he was so full…his stomach was so heavy…it felt so good…it felt so incredibly good! Every inch of his body was buzzing with ecstasy. Speaking of which…considering he now had the villain in custody, it was time to finally get some relief from this aching pleasure. The bastard wasn’t going anywhere. All that talk of steering him around like a car before making him vomiting everything up was unfound nonsense. He was the Hero who fought with his fat – he knew how to handle his own stomach. Only place the bastard was going was jail but that would be after Fatgum indulged himself a little bit. He had patiently waited for the villain to entirely fill him up so now was the time for his reward! 

Fatgum swallowed hard, pushing up onto his elbows. One look down at himself and he nearly came in his pants. All of his fat was back and then some – his pecs were now closer to boobs and could be some adolescent boy’s jacking off material; his stomach…fuck, he was bigger than he’d ever been – swollen and stuffed to a point that he didn’t know if he’d ever be able to burn everything off; sitting up further revealed that his thighs were extraordinarily plump as well. Fatgum chuckled. His suit was ruined, ripped open by how stuffed he was. Fine with him – it was easy enough to replace. Also made it significantly easier to get his throbbing, aching cock out from the torn fabric that had been his pants and underwear. He wrapped his thick fingers around his length, sighing in relief. It was a little bit difficult to move like this but he’d masturbated while at peak fatness before so he knew how to arrange everything. He kept his heavy lidded gaze on his engorged belly as he rapidly pumped his sopping wet cock. The movement of his arm caused his belly to bounce and jiggle. Sharp bursts of pleasure crashed through him. Copious amounts of precum leaked out of the slit, making it easier for his hand to move. 

He could feel the villain moving around inside him. Dumb bastard was probably figuring out right about now that his plan wasn’t going to play out in his favor. Fatgum’s grin grew even wider. He slid his hand up to the head of his dick, rubbing the tip against the calloused palm. A loud moan tumbled out of his mouth. Ah, fuck…good, this felt so good…only thing that could make it feel even better was if he had a tight mouth or hole to wrap around his throbbing dick! Fatgum chuckled. That gave him an idea. He could move easily like this. Years spent learning how to handle himself at his fattest had given him an agility that made him seem like he weighed practically nothing at all. What the villain said was true – police and Pros alike were looking for him, and it would be beneficial to take him into custody as soon as possible…but, he supposed, his detainment could wait a little while longer. This sensation of being stuffed so incredibly full…he couldn’t let it go just yet. Since the villain was trapped inside him, there was no harm in waiting a few hours before handing him over to the cops. Besides, if he did it now, what was he going to do? Walk out there with his dick hanging out and puke the villain up in front of them? No, extracting the villain would have to be a private matter. 

Only made sense that he head somewhere private for this extraction, then. And, while he was there, no harm in having a little more fun! Yeah…he was a Pro, after all. He deserved a little reward for putting in so much hard work to get this dastardly villain apprehended. For right now, though, he was reaching the end of his endurance. Cumming…fuck, fuck, he was gonna cum! Dropping his hand back down, Fatgum sped up the pace, squeezing and stroking cock. Just as he felt himself getting right to that edge, he brought his hand back up and pressed his thumb down hard on the frenulum. A loud moan rippled up his throat. His hips bucked clumsily. He came with a shuddering and harsh gasp, spraying thick ropes of cum everything. The strength of his orgasm sent him falling backwards, trembling and twitching as heavy, scalding waves of pleasure rushed through him. A dense, golden fog swamped his mind. Every nerve in his body sung with rapturous delight. His orgasm didn’t so much as end as lingered for several moments, kissing and caressing his body, leaving him feeling both drained and invigorated. 

Panting shallowly, his plump limps shaking, Fatgum waited until the world stopped spinning before sitting back up. If there had been any doubt in his mind that maybe he shouldn’t delay in handing over the villain to the police, that orgasm absolutely destroyed it. More…more, more, more, he wanted even more…Shakily getting to his feet, Fatgum tried to get his clothes back into a presentable manner but it was no use. Looks like he was going to be using the back alleys to get home. Pulling out his phone, he quickly punched in the number of his main contact in the police. They wouldn’t question him if he said that he was tracking the villain down to another location, nor his insistence that they let him handle it. He was a Pro, after all. While they were waiting on his word, he would carry himself on home and further indulge himself. That would require some more calls to make sure that he wasn’t having fun by himself but it wasn’t like the villain was going anywhere.
