***WARNING*** This one is even filthier than the last. If heavy scat or castration bother you, turn away.

He opened the door, and as soon as he did, he realized that he shouldn’t have. The reality wave which pushed it’s way out and over him–it was different than the others had been. More forceful, and far less wiggle room. The others seemed to have melded around him–but this one…this one simply forced its will on him, pressed down on him, contorting him and his mind until he nosed his way into the room, crawling on all fours, feeling his belly scraping across the floor underneath him as he let out a snort, and saw his master across the room.

Master–he loved him. There was no question in his mind, no doubt–just universal adoration when he looked at the ten foot tall man, naked–his body covered with grimy fur, his beard reaching his belly button, muscular and handsome and…and everything that Terry–no, not Terry, his name wasn’t Terry anymore, he was Porky, Porky was the name Master had given him, back when he’d finally enslaved him, back when his son had taken him and declared ownership of him, like Porky had always known he would.

“Get over here pig,” Caleb growled, and Porky crawled over, eager to serve, and when he came up next to him, Caleb simply said “Open,” and Porky obeyed. Opening his mouth, and allowing his master to tap the ash from his cigar into his mouth, Porky doing his best to not think about the heat of it, and just swallow it down like he’d learned. He was his Master’s preferred ashtray after all–he’d been doing it for years now, and he stayed there, mouth open while his Master surfed the internet, and all Porky could do was admire him.

Porky hadn’t always been Proky–he had been Terry once upon a time. And Master had been Caleb, his son, but Terry had always been afraid of him. His son wasn’t like him–Terry had been weak, but his son was strong and powerful, far bigger and mannlier than Terry could have ever hoped to be. He remembered all those long nights, when he couldn’t sleep because he could smell his son in his bedroom, how he’d jacked off, over and over, imaging his massive boy dominating and fucking him–enslaving him. Years ago, Terry had finally worked up the gall to ask. He’d crawled over to his son, and begged–begged for the privilege of serving him, and Caleb had agreed. He wasn’t Caleb’s father anymore–he was Porky, his pigslave. And Caleb wasn’t his son–he was only his master–all he’d ever wanted. He took another mouthful of ash and swallowed it back, taking a sniff of his son’s musk, of his shitty ass. He wondered if it needed cleaning–Porky would clean it for him. He loved cleaning out his son’s ass and eating his shit and drinking his piss and eating his cum.

That was why Caleb had made him a pig, instead of a slave. See, he’d known all about his father’s filthy interests. He’d left the toilet unflushed on occasion, just so he could listen as his father used to drink his son’s reeking piss from the bowl or eat the turds he’d left behind. He’d made sure to stash his cum soaked jockstraps for his father’s pleasure. Of course, his pigslave hadn’t felt any pleasure in a long time. He’d had his one inch cock locked up long ago–but he didn’t need to cum. In fact, he couldn’t cum–his Master had taken his balls away after five years–now, his scrotum had two half pound steel weights in it, which had successfully stretched it to the ground. That is, if he hadn’t been wearing his diaper. He’d been fucked so much my his master’s massive cock that he couldn’t close his ass anymore–and Master hated it when Porky made a mess in the house.

“Clean my foreskin, Porky,” Caleb said, and with a happy grunt, the pig worked his way under the massive desk his son had had custom made for his massive physique, and started licking under the massive foreskin his son’s foot and a half long cock had shrouding it’s head. The cheese was thick and reeked, but Porky wouldn’t have it any other way, and he snorted and squealed softly in appreciation. He was almost done with it, when Porky heard a loud fart erupt from his ass, and shit started packing its way into the back of his diaper, and he was surprised for a moment…but why surprise? He was used to shitting his diaper by now, why would he be surprised at all? And yet, part of him felt like he’d never done it before in his life, and that everything about this situation was just wrong–but how? This is what he wanted, what his master wanted. Everything was perfect…right?

One of his Master’s big feet curved around to the back of Porky’s diaper and started rubbing up and down the padded bottom, and the pig felt the shit start spreading up and down his crack and around to his caged cock, and he hoped his Master was getting horny. He’d really like to get fucked–he needed a good fuck really bad, but he knew better than to ask for one. That wasn’t what pigs did. Pigs did what their Master’s said, no matter what. They were ready whenever their Master’s wanted them to be. Still, he kept cleaning out his Master’s foreskin, and it was starting to harden–he let himself get a little hopeful.

“Pig,” Caleb said after a few minutes, “Get out of there–that nasty shit stink of yours is getting me all horny.”

Porky couldn’t crawl out of there fast enough, as as soon as he did, his massive Master stood up and ripped the diaper off of him, revealing the pig’s shitty crack and he let out a little groan, got down and worked his massive cock deep into his pig’s ass.

It had taken Porky years to feel anything beyond pain when his master fucked him, but now he was finally used to it, and took the entire shaft up to it’s ass. He could smell his shit now, and he was hungry. Thankfully, his master pushed his diaper under his belly, smearing shit all over it, before it ended up under Porky’s face, and he started licking the diaper clean, grunting and snorting the entire time as his master abused his hole.

“I have a feeling this is gonna get messy,” his Master said, “I think we’d better take this down to the basement.”

Porky felt his Master wrap his arms around his massive gut, and hefted him up off the ground, shocking Porky. He weighed close to 600 pounds now, and his Master was so strong he could pick up with no real effort. What a wonderful master he had! He was so lucky that he could serve him as his pig. With his entire cock buried up Porky’s ass, Caleb left his room and started heading downstairs, and Porky witnessed something…strange. The waves of reality he’d felt…whenever they turned a corner, he could watch them sweep out from where they were, changing the entire house as his Master moved through the house, like reality kept shifting and adjusting to his very whim. It was awe inspiring–he’d had no idea that his master was capable of something like that…and yet…

Something clicked in Porky’s head, and he realized now that this had happened to him before–not this, not being carted around on his Master’s massive cock, but he’d…changed, before. Reality had changed before, and…and Master was the cause of it? But then…maybe things shouldn’t be like this…but why shouldn’t they? He was happy, serving his Master. His Master as happy with him as his pig–why should things be different? How could things be different?

His concern was derailed as they started walking down the steps into the basement, and Porky watched the workbench and tools shift and change into a massive complex–a fully equipped sex dungeon, complete with a cage where Porky lived when his Master didn’t need him. As they walked down the stairs, the pig suddenly noticed a warmth in his ass–but it wasn’t his master cumming, was it? No, there was too much of it–he was pissing in him, filling him up with his piss, and it felt wonderful.It was no surprise then, when his Master headed for the tub–he was apparently in a dirty kind of mood. Porky loved it when his Master was feeling dirty–because Porky was always eager for filth. He was a pig after all.

Caleb hefted his pig over the side of the massive tub–a massive, converted hot tub which had had it’s drain permanently plugged with cement, and there, standing in the middle of the tub, he grabbed his pig’s meaty love handles and started fucking him up and down on his massive cock, feeling his piss run down his shaft as he fucked him, then down his hairy legs where it pooled around his feet. He shifted Porky’s angle, and started thrusting again, and the pig let out a sudden grunt as his master pummeled it’s bladder with his massive cock, and he started to piss uncontrollably, feeling it soak the underside of it’s belly, before running down it’s scrotum, which swung to and fro as his Master fucked him, and between both of their streams, the two of them managed to fill the tub up a couple of inches before they ran dry. Now though, Caleb didn’t care–the stench filling the basement was driving him to new heights of horniness, and he was fucking his pig up and down on his cock as hard as he could sweating from the exertion, Porky simply biting it’s lip and hanging on as best he could, until with a roar, he came, the massive amount of cum from his huge balls flowing out almost immediately from Porky’s entirely loose hole and joining the piss and shit already pooling in the tub, and then Caleb finally set Porky down in the tub, who immediately shoved it’s face into the messy pool, drinking up as much as he could.

Standing over him, his Master just watched the pig debase itself, and then he did something that Porky did not expect–he stepped out of the pool, shook his head, said, “No–no this is…just, not this,” and then stomped his way back up the stairs, slamming the basement door behind him. Porky didn’t know what to think for a moment, but then he realized he must have done something wrong–but what? What could be have done wrong? He’d been a perfectly good slave today…hadn’t he? Besides that time in the bathroom, when…when he’d…

When he’d told his Master no to to fuck him? No, he wouldn’t never do that, he could never do that, it just wasn’t in him. He was too weak, too small, too much of a desperate sub to ever say no to a man as big and powerful and important as his master. But he was shivering in the tub–he could clearly remember doing it, but…but how could he have? He’d been serving his master all day, like usual–they hadn’t even been in the bathroom downstairs, had they? The room was starting to spin, and it felt like…like Proky could start to see little tears happening all around the room, little tears in reality, like the walls and floor were shaking and vibrating to pieces, and he shut his eyes but the cracks were still there.

“No…No, I love my master, I obey my master, I obey, I obey, I obey, I obey…” Porky said, crouched down in the scummy tub, eyes clenched shut, repeating his mantra, and he felt the world start…healing itself again. He couldn’t even tell if it was the world which had been cracking…or just his mind. It was so disconcerting. In the end, he clambered out of the tub and crawled over to his cage, shutting the door behind him, and in the cramped, confined space he’d come to know as his home, he felt a bit more comfortable and sure of himself. Still, he didn’t move, and just stayed there, knowing he’d already broken the unspoken rule when he’d climbed out of the tub, but hopefully his master wouldn’t be too angry, not like that other time…that other…place.

Now that he was calm, he carefully started working through his head, finding other memories that just didn’t…fit. How his daddy had smoked his cock to a nub while he’d ridden his big cock. How he’d made his son a massive dinner, how they’d fucked…it didn’t make any sense, but as soon as he sensed the cracks starting to open again, he shut them all away, and just stayed in the present. The past didn’t matter–it wasn’t important. He just had to focus on being the best pig he could be, and the rest would be ok. His master would make sure of it. Everything would be ok. Now, all he had to do was wait.

His master didn’t keep him waiting too much longer–he heard a door upstairs open and close, and then…as he came downstairs, he could see the walls and ceiling…bulging out, as though reality were pulsating around him, and there were those cracks again, and Porky shut his eyes as tightly as he could, until he heard the basement door open, and then the pressure was all around him again, reality twisting and yanking and contorting him, and this time, it really was painful, like he was a piece of dough that had been kneaded so far as to become nearly inelastic, but it refused to stop. When it finally came to a stop, he was gasping for air around his thick cigar, and started taking a few deep puffs, the tobacco helping him calm down, as he tried to process what had just happened to him.

“Hey daddy bear,” his son’s voice called out from the top of the stairs, “What are you doin’ down here all alone in the dark?”

Terry felt his cock stir, and he adjusted his monstrous tool in the crotch of his pants, and looked up the stairs to where his massive son stood. God, was he even bigger than before? How was that even possible? His head struggled for context, as his eleven foot tall son thumped down the metal staircase Terry had had to put in years earlier, after his son had broken the wooden one that the house had had before…or still had…or…something. He felt like he needed to vomit–hadn’t there been…a tub here? Or had he just imagined it? The basement was equipped with every sort of dungeon tool he and his son had been able to purchase, but never a tub–why hadn’t he thought of that? Damn, that would be hot, the two of them filling it up with their piss and then wallowing in it, fuck…hadn’t they just…just done that?

“What’s up Dad?” Caleb said, “You alright?”

“Yeah…yeah, I’m fine, I just…feel really strange is all.”

“Well, I bet I know what could make you feel better,” Caleb said, slipped his hands under his dad’s arms and then lifted him up into the air. The sense of powerlessness, of being lifted up by his Master–no, not master, his son, always his son, they’d always been equals…well, sure, they’d played some scenarios before, but nothing serious–

He groaned as Caleb ripped open the crotch of just old jeans with his teeth and swallowed his entire foot long cock in one go, resting his dad on the crest of his gut as he sucked him off. God, how had he, at all of five feet, managed to help conceive such a monsterous man? Not that he was complaining of course, but for some reason…none of this seemed possible, nothing seemed right–

With a twist of vertigo, Terry lost his balance and slipped off his son’s gut landing hard on the floor, his head slamming into the concrete, and he rubbed his head, checking for blood, but there wasn’t any, thankfully.

“Fuck–Dad, are you alright?” Caleb said, looming over his father.

“Yeah–yeah, I’m good, I just…just lost my balance is all…I don’t…I don’t think I can…” Terry said, but the vertigo hadn’t let up, and he leaned over and vomited onto the floor. The world, it was starting to rip again like before, and he…he couldn’t take it. He groaned and laid back, trying desperately to hold onto himself as the world threatened to rend apart, but he opened them once quickly, and saw…his son in so many different ways. Fat, old, massive, hairy–he could barely keep track of them all, and then his son had him in his arms, and was rushing up the steps, all the way to his room. He laid his Dad down on his bed, and then sat down at his computer–a specially ordered one for his massive frame–and he started typing, and then, as he finished and hit the return key, another wave rippled out, but this one was entirely different. Instead of trying to bend and twist Terry into some new shape, it felt like it was unfolding him, and as it washed over him, the nausea and vertigo disappeared–but in it’s place can a realization of what had happened over the course of the day…and he screamed.

“Dad! Dad, calm the fuck down dad!” Caleb shouted, pinning Terry down to the bed. They were still in their last forms–all Caleb had done was undo the reality conforming option on the program he’d brought home with him that afternoon, and being twice as tall as his dad, he was able to hold him down easily, not that Terry cared in the least. He kicked and fought anyway, and finally Caleb let him up and he sprinted from the room and into his bedroom, slamming the door behind him, and he slumped back against the wall, just…staring at his hands. His grimy, filthy hands, and his grey beard, and his filthy clothes, and he just started stripping it all off of him in a rush. How many versions of himself had he been today? He couldn’t even keep track of them all in his head–they’d all rushed forward in a massive jumble. Who was he now? Was he actually himself, or was he just some new twisted version his son must have concocted? He stepped out of his pants, naked, and walked in front of his mirrored closet, and nearly sobbed. He…he was disgusting to look at–tattoos and piercings all over his body, missing teeth, and yet looking at himself, his massive cock started to get hard, the footlong cock that stretched down nearly to his knee he was so short, but his gut was so big that he couldn’t even see it when he craned over. He turned away before he could get anymore aroused and do something he might regret, and ran into the bathroom to run a hot shower and get clean.

There was a pounding on his bedroom door, “Dad? Dad, please–we need to talk–I can explain!”

“Stay the fuck away from me, you fucking freak!” Terry shouted, “What the fuck were you thinking! Look at what you fucking did to me!”

“Look, I know…I know I got a bit carried away, alright? I just–”

“A little carried away?” Terry shouted, “A little fucking carried away?” He stalked over to the bedroom door and flung it open, but when he saw his massive son standing there–or rather, when he found himself face to face with his son’s two foot long cock, words failed him utterly, and his anger dissolved into…pure lust. But before he let it overwhelm him, he stepped back in and slammed the door, but he could smell him, he could fucking smell his boy’s nasty funk through the goddamn door and fuck if his son wasn’t the hottest piece of man he’d ever seen!

“Dad…” Caleb said, “Dad, it’s going to be ok!”

“Stay…stay away from me Caleb, please, just change us back, please…” Terry said, but the anger was gone. He was pleading now–desperate, and he heard the knob twist, and the door start to push open, and he tried to push back, but his son was so much…stronger than he was, god, he was so…so proud of him, and from where he was sitting on the floor, looking up at his massive boy, all he wanted to do was fuck him.

“Dad, Look…I…”

Terry couldn’t even see his son’s face past his massive ball gut, but he didn’t care. He stood up, walked over and just started licking the foreskinned head of his cock, unable to resist, digging his tongue under the folds for his son’s delicious cheese, disgusted with what he was doing, but also utterly unable to contemplate doing anything else.

“Dad, you…you don’t…oh…”Caleb said, and groaned, his cock leaking precum which Terry drank down, but the flow was so heavy a good amount of it just dribbled down into his massive beard. “Dad, please…we…we have to…God damn it, that’s fucking enough!” Caleb said, stepped back, grabbed his dad and hefted him up to his eye level. “Dad, can we please just talk about this?”

“Why, son?” Terry said angrily, “You obviously just want me to be a short, nasty old daddy bear desperate for sex with his son, and now that…that I can’t fucking keep my hands off you, you fucking want me to stop? Just…just fuck me, already. Fuck me, and…and fuck, let me drink your piss, and eat…eat your goddamn shit, and–”

Caleb gave him a good shake, and said, “Enough!” Look, I know I fucked up, alright? I get it! I’d put everything back, if I could but…but…well, I kind of messed up the program…”

“What fucking program? What the fuck are you talking about?”

Caleb heaved a sigh, and fell back onto his ass, the house shuddering under his weight, and then he set his dad down on his big gut, and explained the story as best he could. He had been at the mall earlier that day, but he hadn’t been at the mall with friends. He’d been there by himself, just being a loner, when he’d spotted this new curio shop. They’d had a discount electronics section, and the shop owner had recommended this strange program to him. Caleb had thought it was a photo manipulation program–some photoshop knock off–but it had been a bit more…expansive than that. It turned out to be a program which could completely alter the face of reality, and, well, Caleb had let things get a little out of control.

“Look, Dad, all…all I really wanted was for you to be happy again, and I’d always…well, I’d always thought you were hot, so I thought, well…why not?”

Terry just glared at his son, “So you turn me into all of those…those people? For fun? That wasn’t fun, that was a nightmare!”

“I don’t know, you seemed to have enjoyed most of it.”

“Porky was not–fucking–enjoyable.”

Caleb blushed, “Yeah…I…I don’t have an excuse for that one, that one…that was a mistake.”

“No, this whole thing was a mistake. Just…just turn us back, and let’s get rid of it, and we can pretend like none of this ever happened, alright? Let’s just put everything back the way it was.”

Caleb was silent, and hung his head, “I…well, I can’t.”

“What do you mean you can’t?”

“Look, dad, I…I was running the program so that, however I changed myself, reality would automatically adjust itself to conform to me–that’s why, well, you probably have had a strange afternoon. But what I didn’t know, was, well, when you twist reality too much for the people around you, apparently some strange shit can happen. I mean, when we were down in the basement, you started…you flipped out. I mean, not just your screaming and stuff, but your body too. It looked…I don’t know, like it was stretching and collapsing and…and I just got scared. I got scared, so I ran up and turned off the reality adjustment, and that collapsed everything down together, but…well, I was just looking at it, and the program’s locked down.”

“What?”

“It’s locked down. I can’t change reality anymore, until it normalizes. I took a closer look, and apparently the program won’t unlock until it can purge everything from this reality that doesn’t belong. Like…like our memories, and…and that sort of thing.”

Terry just stared at his son. “Are you telling me that we’re going to be stuck like this?”

“Yeah…I mean, not for too long, like less than a day. The bar says it’ll finish sometime tomorrow morning.”

“Well, we can just change ourselves back then.”

“No, Dad, you don’t get it–we won’t remember what we were like. We won’t even remember that we’ve used the program. None of that will have happened to us…we’ll be who we are now, and it’ll be like that’s who we’ve always been…I’m…I’m sorry dad, but I’m telling you the truth. This…this is kind of who we’re stuck as.”

Terry didn’t say anything for a second, he just let that sink in. “You mean…you mean, I’m stuck as this five foot dwarf, a fucking dwarf who can’t–can’t stop thinking about how much he want’s to have…have filthy, nasty sex with his own son? His…his eleven foot tall son, who’s twice the size of me, and stinks like a fucking outhouse?”

“You don’t have to be a jerk about it, dad! I said I was sorry!”

“Well sorry isn’t going to cut it!” Terry shouted, and climbed down off of his son, “I had a life Caleb, I was…I was…”

He couldn’t remember. He focused really hard, as hard as he could, but it was like staring through a thick fog–he knew what was there, but he couldn’t see it. The more distant the change, the harder it was to see, and his old life, it was gone–he hadn’t always been gay, had he? Had…Hadn’t he? He didn’t want to be straight. that was for sure, but…wasn’t there? Sure,he loved his son…

Terry shouted, and punched the wall in anger, but it was gone–it was gone, and it wasn’t going to come back.

“Dad…Dad, look–I know this isn’t what…what you would have wanted, but we’re going to be happy at least, right?”

“Don’t you fucking say anything–nothing you say can fucking make this right!” Terry shouted at his son, but Caleb didn’t say anything back–he just reached over, grabbed his dad, and pulled him into a tight hug. “God damn it Caleb! Let me go! Let–let me..” he said, but then he was crying, and his big son was holding him tight, and everything…everything wasn’t really so bad, was it? He hadn’t wanted this, no–but he wanted it now, he wanted it…badly, and that scared him even more.

“Look, dad–I…I know I can’t make things right, but…but look, maybe I can make things better, you know? Here, come on. I can’t fix reality, but I can make some limited changes–”

“No–No more changes, I’m done.”

“Well, I was going to make you taller…” Caleb said, grinning, “But if you like being a ‘dwarf’ now, I think it’s damn sexy, myself.”

“But you said you couldn’t change anything,” Terry said, suddenly suspicious that his son might have been lying to him before, “If you can change me, why can’t you just change me–us–back?”

“Because you–the ‘old’ you–could have never existed in this reality. Even if the program let me make the change, which I don’t think it would, by tomorrow morning you’d be back to this, or something close. But, if I just make a few tweaks–some changes that this reality can absorb and integrate–then I think I can make things a bit better. So look–you tell me what I can do to make you better–this you–and I’ll do the best that I can.”

Terry just looked down, “How…How can I trust you? How can I ever trust you again, Caleb? I mean, I can’t…”

“Dad, I can’t undo what I did–if I could, I would. I never…I never meant things to get this out of hand, and I’d…I’d always thought I would just put things back the way they were, eventually. But I can’t, so…so let me make it up to you. Come on, I know you had fun some of the time…tell me what you liked best.” Caleb sat down next to his dad again, reached over and started toying with his cock.

Caleb let out a groan when his son touched him, and all he wanted to do was throw himself at his boy and just fuck, but he held back. Still, he wasn’t happy like this, really, so he might as well take advantage of his son’s offer. What had he enjoyed? How far back could he remember? He…he’d liked how it had felt being fat, actually–as the chef. He’d been massive, sure, but so…confident. How fucked up was that, that he’d actually enjoyed being huge, obese gainer? But it was true. “I…I liked being fat–actually. When I was the chef. And…and I really liked the whole…the whole smoking thing. Not being your cub, but just…smoke. And I gotta say, these tattoos are kind of sexy. Actually, it was probably most fun being that redneck daddy of yours. The accent scared me at first, but…and god, it’s so messed up, I know, but being…being this filthy, and seeing you this filthy, it turns me on so much, and you know, I actually kind of liked shitting myself as Porky, with that diaper and–” Terry blushed and stopped talking, suddenly embarrassed. “But mostly I–I’d like to be taller. Just forget the rest of what I said, I…I didn’t really mean any of that.”

Caleb just looked at his dad for a second, before he said, “You really did enjoy yourself, didn’t you?”

“Just make me taller, would you?”

Caleb grinned and said, “Sure thing dad,” and got up, smirking, lumbering into his room and sitting down at the computer, “One taller dad, coming right up–but not as tall as me,” and then under his breath added, “and…maybe a few other…small details…”

“Wait, what?” Terry asked, but before he could get closer to see what his son was doing, Caleb was already typing away, and suddenly, well, every step threw him off balance as he tried to walk, his legs thickening and lengthening with each stride, and it was all he could do to not fall over when he just stood still. Well, he was definitely taller–if his son was eleven feet, Terry probably capped out around eight, or maybe nine. It was strange seeing everything from that high up, and the sense of vertigo hung around for a few moments until he became more used to his new perspective. It was then that he realized that Caleb was still typing–and that he was still changing. His final body had been mostly muscle–and at his five foot height, he couldn’t have weighed more than 150 pounds, but that was rapidly changing. Looking down, he saw fat start bubbling up under his skin, shrouding his physique, but it didn’t stop there. His gut ballooned out, and then softened into an apron like the one he’d had in the kitchen–except bigger. Hell, he’d been one fat tub of lard then, but at his new height, he had to be over six or seven hundred pounds of blubber.

“Caleb! Caleb, I fucking told you to just make me taller! What the fuck is this–I don’t–” Terry started to say, but Caleb had already gotten up from the computer, walked over and drawn him into a deep kiss, pulling his fat body into his big gut and muscular chest, and Terry couldn’t help but just melt, especially when his son started fiddling with his big nipples, and jiggling his flab, his cock was so hard…

“Dad,” Caleb said, when they pulled apart, “Stop thinking so much. I know what you want, now quit worrying about who you were, and let me make you happy–let me…make you feel good.”

“Caleb…please…I…” Terry started to say, but his son shushed him.

“You know, I think we need to keep that mouth of yours occupied with something else, don’t you?”

Caleb sat back down at the computer, and Terry just watched him. He should stop him, shouldn’t he? And yet, he was…so damn curious, and horny, and excited. He needed something to calm him down. He reached into the front pocket of the massive overalls he was wearing, pulled out his can of chew and started packing it into his lips on both sides, his cock pulsing as he packed himself full. He fucking loved the sensation of a big lipper, and it only got better when he pulled out one of his massive, 70 ring cigars, stuck it in his mouth and lit it up, taking a massive draw, and pulling out as much spit as he could from the leaves in his mouth. “Aww, sheet yeah boy, feel’s damn fine…” he said, and he had to think about it for a second before he realized that the heavy southern drawl hadn’t been there a second before. “Fuck, ya went ‘n changed me again, didn’ ya…”

Terry knew better than to ask his son to stop what he was doing, and if he were honest–he liked what Caleb was doing, and didn’t really want him to stop. Hell, they’d been fucking each other for so long, why should he be embarrassed? He felt like that wasn’t quite right for some reason, but if he couldn’t remember a time when he and his son weren’t desperate to fuck…then was that really true anymore? Sure, maybe at some point, in some other reality, but in this one, well, in this one he was gonna be one hot stinking redneck, with the sexiest son in the whole neighborhood.

Looking down at himself, he saw that Caleb still wasn’t finished. The tattoos on his arms grew together into solid sleeves, and he watched the patterns worm their way over the rest of his body, and under his overalls. He figured that, at this point, most of his body was probably covered. His beard and hair grew out a bit further, and he pulled his thick, greying hair back into the ponytail he preferred, feeling the hair become greasy and slimy as he gripped it. Yep, apparently his boy wasn’t satisfied with his hygiene either, and before too long he just…well, stank. But it was a hot, musky, filthy stink, the kind of stink he loved, and he grinned, squirting some tobacco juice from his mouth, feeling it run down into his beard. “Damn boy, ya sure ain’t foolin’ round none.”

“Nope,” Caleb said, “I don’t think the changes will stick too much–reality will probably reassert itself by the time to program runs its course, but I figure we might as well have a little fun in the meantime, eh Pa?” Caleb stood up, and when he did, Terry say that his son wasn’t just a couple feet taller than him anymore–apparently his son had had a few changes in mind for himself too.

“Gawd damn, son, yer jus’ gonna make me feel short again,” Terry said, taking another massive draw off his huge cigar.

“Hey, you said that ya didn’t wanna be a dwarf–well ya ain’t a dwarf,” Caleb said, his own speech patterns shifting to match Terry’s, “but ya didn’ say Ah couldn’t git taller.”

Caleb was growing taller–probably to about twelve feet–as tall as the already oversized ceilings in their house. He lost a bit of his round gut, but what he lost in fat he made up for in muscle–he was becoming damn ripped, in fact. He still had a big gut, but on top of that were two massive pecs, and his biceps and thighs were making Terry’s mouth water, more tobacco spit dribbling down his beard. He didn’t seem nearly as unkempt as his father, his beard and hair were trimmed up quite a bit shorter, but damn did he reek. Not like Terry, who had a certain lazy stench of filth about him–Caleb reeked of sweat and workouts and…sex. He also gained a substantial number of tattoos, and fuck if he didn’t look like a sexy fucking beast, standing there a few feet away. Terry wondered for a moment what someone would think if they stumbled upon the two of them…but he didn’t care–he just didn’t care one lick. He just wanted to fuck his boy all night–

Terry was suddenly caught off guard by a massive fart ripping out his ass, along with something else. It caught him by surprise, when the stench of shit slammed into him, and he froze, realizing that he had just packed the ass of his overalls with a massive load of shit, and Caleb walked over, reached around with both hands, grabbed his Pa by the ass, smashing the load around as he pulled his obese father into a deep kiss. The two of them spent a few minutes chewing Terry’s tobacco between the two of them, brown spit running down both of them, as Caleb kept working the shit around in the back of his dad’s overalls until it came around the front, coating his balls and cock…and fuck if it didn’t feel amazing. He couldn’t…he couldn’t even be ashamed of it anymore, he didn’t care, it felt so good, so nasty and just so…so right.

“Piss fer me Pa, come on, soak these fuckin’ overalls a yers…” Caleb whispered, and Terry did as he requested, taking a drag off his cigar, before blasting a full load of piss into his overalls, feeling it soak into the shit, and it ran down his legs and into the rubber boots he was wearing. He could feel the shit and piss squishing between his toes, and he let out a deep groan which his son silenced with another long kiss. “You like it…don’t ya Pa?”

“Fuck son, I fuckin’ do–how fuckin twisted is that?”

Caleb chuckled, pushing all of the tobacco back into his dad’s mouth, “Not as twisted as this.” He then gave Terry a shove, and he fell back, landing on his massive ass, feeling the shit squish around with the impact, and then his son was on him, unbuckling the latches on his overalls and pulling down the front. Looking down, Terry could see his cock was coated with piss and shit, but before he really had a chance to think about it, his son was sucking it clean, deepthroating his whole, two foot long cock.

“Oh fuck yeah, boy!” Terry said, twisting and yanking at his nipples as he ground his shitty crack into the floor of his son’s room, “You fuckin’ love the taste a yer Pa’s shit ‘n piss, don’t ya? Yeah, yer just a nasty fuckin’ redneck pig like me.”

“Well, like father like son, ya know?” Caleb said, pulling off Terry’s cock, shit smeared across his face, “Ya really oughta try some a this Pa, I think ya’d love it. Here, I know jus’ what tah do.” Caleb scooted down to Terry’s booted feet, and pulled off one of his boots, still full of his  own piss, and took a whiff. “Whoo wee, Pa, ya sure do love yer rubber, don’t ya? When’s the last time ya took these off? Still, Ah think yer gonna love it, though,” Caleb said, and brought the boot up to Terry’s lips, “Open up Pa, ‘n taste yer fuckin’ filth.”

Most of it went down his fat gullet, but plenty of it washed out and down his front, where his hands rubbed it into his fatty folds, and hell if it wasn’t one of the filthiest things he’d ever tasted, his piss, shit combining with the tobacco in his mouth. When he finished, he realized he’d accidentally swallowed some of his chaw, he’d been so eager for his own waste. His son yanked off the second boot and fed that mess to his Pa as well, afterwhich Terry worked up a mighty belch. “Fuck boy, that hit the spot.”

“Ha, don’ tell me that was enough tah satisfy a big pig like you.”

“Satisfied? Hell nah, I could put away plenty more where tha’ came from!”

“Oh is that so, Pa?” Caleb said, grinning, “Well, it just so happens I might have some more…if you want it.”

Looking up at his massive son, over twice as tall as a normal man now, Terry tried to get a grip on himself, but it felt like the entire universe was just spinning out of his control. Of course he wanted to eat his son’s shit–and he quickly realized, it’s not like this would be the first time. He tried to remember that he hadn’t always been this fat ass redneck, but it was easier to remember that he and his son had been each other’s toilets for years now, and they both fucking loved every second of it. Worse–or perhaps better–he couldn’t even be ashamed of it anymore. “Fuck yeah, show me what ya got fer Papa, boy,”Terry said, letting himself smile, his gut giving a hungry rumble of eagerness.

Caleb dropped the grimy gym shorts he was wearing, and saw his son had on one of his filthiest jockstraps, and he gave a little moan when the stench hit his face. Caleb straddled his dad’s chest and shoved the stinking piss, cum and shit stained mesh into his father’s mouth and nose, grinding it back and forth, and said, “You wanna be my big piggy toilet today, Pa? You want me to cram a big load a shit down yer fuckin’ throat?”

Terry wasn’t listening, he was chewing at the jock and his son’s massive bulge, his cock even larger than his erect two foot tool beneath his big fat gut. He didn’t care anymore. He loved his son so much…especially the massive logs of shit Caleb proceeded to feed his father, making sure of overload him faster than he could swallow, to give Caleb some to lick out of his filthy beard afterwards–but not before his father had worked both of his fists up his hole, milking his prostate until he’s shot a gigantic wad all over his father’s fat gut. Still, the two of them were insatiable, and as the timer on the computer continued to count down, and their memories of their previous identities continued to dwindle, the two of them kept on, fucking, feeding, fisting, pissing, shitting and licking the night away, until they’d finally collapsed, exhausted, on the floor of Caleb’s room, and cuddled each other to sleep in their own filth.

The next thing Terry knew, he was stretching in his son’s oversize bed in his room, worming his way out of his son’s grip and pulling himself off his son’s big dick which had mysteriously snuck its way up his ass sometime in the night. The bed underneath him was sopping wet, but he was used to that–both he and his boy had a habit of wetting and shitting the bed in the night, not that either one of them would have it any other way. He sat up and stretched, feeling the dry shit on him crack as he did, and he stood up, giving his hole a scratch and licking off the scum his fingers pulled away. Waddling over to the mirror, he took a look at himself–he could still distantly remember that he hadn’t always been like this, but it was simply an abstract fact–he had no actual memories of his prior identities.

He was shorter than the night before–reality must have not liked him being that tall. Still, he was bigger than the five feet he’d started out with, but had probably dropped back to about seven. He hadn’t lost a pound of fat though, and on his shorter physique he was absolutely massive now, and so fucking sexy, slathered with shit…He reached around in his flab but couldn’t get a good grip on his cock, and gave up in a huff, looking back at his massive, slumbering son. He could fuck his hole of course…but maybe it would be better to let him sleep a bit more. Caleb could be such a bear in the morning, but taking his Pa’s piss and shit down his throat usually improved his mood considerably. That, and a few cups of strong black coffee. Terry let him slumber and lumbered over past the computer and jiggled the mouse, before sitting down at the desk and looking at the program which had made such a mess of everything.

There was a timer in the corner–it had about five minutes left. He took a few moments to stuff a whole can of chaw in his mouth and light up a cigar, before watching as the clock ticked away the rest of his alternate pasts, wondering if he should feel sad about losing them. But why should he? He was happy–his son was happy. However they might have been before didn’t matter to him all that much, in the grand scheme of things, and by the time the clock elapsed, he wasn’t entirely sure what he was contemplating anymore, as the final, fleeting sensation that things might have been different were erased, and then a window popped up, alerting Terry that the reality synchronization had completed, and that full functionality had been restored to the program.

Terry closed that window…and then smiled, and started looking around the program. There was a lot to it, and a lot that he could do with it…and he realized, that there was nothing stopping him. Eager now, his cock hard, he started making changes to his profile and his son’s, but as he was about to activate the changes, he paused. Something told him that he should wait, and let his son look at it too–they needed to do this together, it was too big to surprise someone with. Still, Terry had something else he could use to surprise his son.

He went over to where his son was still snoring, the covers off, and got down next to his ass, licking his lips, and started cleaning out his son’s hole, listening to him moan and mutter as he slept, and just as he was sleepily coming to, his dad stood up and worked his cock into his ass. “Aw fuck, Pa!” Caleb groaned as Terry drove the entire two feet length into Caleb’s ass, “Ain’t it a bit early?”

“It’s nearly noon, son!” Terry said with a chuckle, gripping his cigar in his teeth, “and ya know how Ah git when Ah’m horny, not come on and open up.” Caleb let his Pa fuck his hole, somewhat begrudgingly, given how sleepy he still was, but after Terry came, he was nice enough to give his boy a blowjob and swallow his load of morning piss too. “Alright son, now come ‘ere, I got somethin’ tah show ya.”

Terry had Caleb sit down at the computer, and then showed his son the changes he’d planned while Caleb was asleep. Caleb was at first a bit skeptical, but as his dad explained it, and as his cock got harder, he was finding less and less objectionable about what his dad was suggesting. Still, he had a few changes he wanted to work in first.

“Ya sure ya wanna go through with this, Pa?” Caleb asked, as they put the finishing touches on the changes, “Ah don’t think this is gonna be reversible.”

“Ah don’t give a flyin’ fuck–this is gonna be so god-damn hot!” Terry said, sucking on his cigar, “Ya done with yer changes yet?”

“Hold yer horses, this is…kinda delicate, ‘n ya weren’t all that careful when ya did it the first time.”

“Ha–’delicate.’ Ain’t nothin’ delicate ‘bout what’s gonna happen here today.”

Caleb laughed, and looked over the screens of the computer again. “Alright, Ah think it’s ready. I made sure it’ll load from the cloud too–cause Ah don’ think the computer’s gonna survive this.”

“Whatever–turn it on and let’s git this show on the road!”

Caleb looked at the computer, and couldn’t believe that they were about to do this, but why the hell not? And then he hit the ok button, and felt himself start to grow, but faster than usual.

“Shit–this is gonna hurt, ain’t it?” Terry said, and Caleb looked over at his dad, and saw that between the two of them they were rapidly filling up the bedroom.

“Well you’re the one who didn’t want to turn on the reality adjuster!”

“Well, then it wouldn’t have been a surprise tah everyone else! Come on, we’d better git outside, if we can!”

Caleb hurried out of the room and down the stairs, and barely squeezed his way out of the front door as he grew too big to fit, but his dad was too slow with all of his flab, and by the time he reached the living room, he was too big to fit through.

“Aww shit, yeah, this is gonna hurt…” Terry said, as his bulk quickly filled the living room, breaking furniture and pushing against the walls of the room.

“Hold on Pa, I’ll help ya!” Caleb said. He was taller than the first story now, and he picked up the family car–amazed that his strength was already enough for it to feel like a heavy dumbbell in his hands, and started slamming it into the upper story of the house, and then into the floor, opening up a big enough hole that his dad could work his way to standing. Together, they demolished the house as they grew, and before long Terry was free, the side of the house was little more than rubble, and the two of them were still growing. By the time they were finished, Caleb had grown to six stories tall–more than twice as tall as their house had been–and Terry maxed out at four stories–shorter than his son, but still massive. Terry looked around at what had been a sleepy neighborhood on a Sunday morning, but hearing the commotion, people had piled out of their doors, and now stood gaping at the two giants where their neighbor’s house had been.

Smiling, Terry grabbed one of the trees from their backyard and uprooted it, rolling it between his hands. As he did, the wood shifted in pattern until it formed itself into a massive cigar, and with a snap of his fingers, it lit up, and he took a deep draw on it, exhaling a massive plume of smoke which settled about the two of them like a fog. He made a second one and handed it to his son, and soon enough they were both pumping out a massive amount of smog. “Well son, let’s head downtown. I think we need tah introduce ourselves tah the community.”

“Sounds like a plan tah me, Pa,” Caleb replied, and together, the two thundered off through the streets.

***

Wellington wasn’t a large town, but it was relatively peaceful, especially on a Sunday. Many of the stores that lined the main street had just opened a few hours ago, and business had been slow so far. Still, it started out as a beautiful morning, but around noon, the strangest thing happened–a massive wall of fog started working it’s way into the small town. People who were outside were the first to be affected, and as soon as it swept over them and they inhaled it, they discovered that it wasn’t fog at all–but smoke.

Several people called the fire department, and a few described the smoke as smelling not like a burning building–but like a cigar. It was soon after that the people first exposed to the fog started to change. It affected the women first, usually a few minutes after exposure, as they were suddenly struck by a crippling pain, their breasts disappearing as their bodies changed, their vaginas sealing up as their cliotori expanded into new, massive penises. Men, however, were affected too, most of them developing copious amounts of body hair, their beards growing out of control as well. A few experienced a sudden shift in age as well–often into middle age or even beyond. This was seen most commonly in teenagers and children, as they rapidly aged into their forties and fifties, their personalities and minds changing along with their bodies.

The fire trucks roared past this chaos and deep into the fog, and so the firefighters were the first to be hit with the second smell. It was something between a filthy locker room, day old sneakers, and sweaty towel–the most powerful, overwhelming musk any of them had ever smelled. It forced itself on them, and as the smoke started changing them, the found themselves growing hornier. The truck came to a halt as the driver started ripping at his uniform, desperately trying to get to his cock, but before he could start jacking off, the man next to him, his beard reaching down to his chest, leaned over and started sucking him off. The men found it impossible to think about anything beyond sex, their minds slowly draining away as the stench drifted into town.

As the people recovering from the changes the smoke wrought smelled–and saw–what was happening, the men of the town being turned into sex-crazed beasts, they started to run away from the sirens towards the other side of town, hoping to escape the musk and the smoke, but after a few blocks–on the other side of the train tracks–they found themselves faced with a different monstrosity–a giant man, hugely obese and stinking of filth, stood in their way, straddling the main street, and before any of them could turn and run back in the other direction, they watched the giant smile, squat, and then shit several massive piles of filth into the middle of the street.

The stench was horrific, but the men found themselves unable to turn away. In fact, they found themselves growing hungrier, the more they smelled it. The weaker willed among them almost immediately gave a few snorts and then charged towards the muck, devouring as much of it as they could, as quickly as they could, but in the end the men started swarming into the shit, all of them starved for it, desperate for it, and as they ate, they began to change one again.

It started out as weight gain, fat packing onto them faster than any of them could have ever imagined, coupled with some growth as well–most of them averaging at about a story tall, with some of the first ones several feet taller. Their human features had twisted–their feet and hands becoming hooved trotters, tusks emerging from their now snouted faces, their eyes feral, perverted and starved for lust. The giant sat down and his minions swarmed over him, licking his body clean of any filth they could find, and with a sigh he let loose a fountain of piss, his pigmen fighting over the stream, thirsty as could be, and desperate to serve their new master.

On the other side of town, the men lost to the stench of musk found their minds becoming duller and duller, and many of them didn’t even notice when the huge, muscular giant strode past them, his massive cock half hard and dribbling a torrent of precum. That–however–they did notice, the smell of fresh cum drawing them like flies. The men drank it down, growing hairier, muscular and muskier as they did, their bodies almost devolving into some sort of beastly form, fanged and clawed and ferociously horny. They fought with each other over it, and the giant stood over them, milking cum from his cock, feeding his beasts, until one of them latched onto the head, drinking more than the rest–becoming the pack’s alpha. It roared at the massive giant, ready to challenge it for control, but before it could attack, the massive man sprayed all of the beasts down with a massive load of piss. They fell back then, immediately subservient after being marked by their master, and came forward, serving him, licking away his sweaty musk and serving his cock and his hole eagerly.

When the town had been emptied of people and divided between the two giants, they met in the middle, their hordes following close behind, and tackled each other to the ground, kissing and grinding their massive bodies together in the street, their hordes swarming on and around them. It was a day later when the two of them finally pulled apart, their hordes exhausted and sleeping all over the ruins of the town, and Caleb and Terry looked at each other and smiled.

“Hey, Burisburg is just a few miles down the road–wanna do it again?”

“Sounds awesome to me–can’t wait!”
