NOV-24 Prompt: M.A.S.S. Inc(ident) at the water plant

(Content Warning: Mass Growth/Weight Gain/Size Growth/Macro)

In the sleepy town of Adiprose River, a group of students from the local college were taking a tour through the water treatment plant. Though such a tour was usually done for little kids or at most high school students, the unit the group were taking focused on the processes in environment and resource management. As such, their tour was more in detail compared to the ones for younger groups.

For many of the students, it was a chance for them to understand the processes by which the plant helps to make clean water for their town and the companies stationed within. For a smaller sect of the group, the tour offered them a chance to build on their readings for their planned thesis and proposals.

But for two freshmen, standing at the rear end of the group, the tour was borderline torture as the guide went on and on about things they didn’t really get nor understand. The two scrawny students dragging their feet as their guide went on about reverse-osmosis or something.

“Josh, this is so boring.”

“I know Mike.” Josh responded out with a sigh as they trailed behind their group. The two students had taken this unit since they needed the credits for the year, and this was famously an ‘all pass’ subject. Yet, neither young man was interested in the scientific explanation, nor the studies and sciences their guide went on and on about that the rest of the group could at least fake being into. Hell, the only reason Mike and Josh hadn’t just snuck off or entirely skipped the outing had been the fact the trip was mandatory for passing the unit.

“I mean, it’s just water. Okay, it is important and we all need it, but it’s so boring,” Mike said, the slim man stifling back a yawn. Shaking his long hair as the hope for the tour to finish up was dashed as they were led further into another room. Turning back to his friend, Mike leaned in, “Can’t wait to blow this and we can finally have our fun.”

“The stuff finally came?” Josh asked, whispering the question as the freshman at least had the self awareness to know it would sound like he was talking about something like drugs.

… Granted, he might as well be considering how hard it was to get.

“Came with the mail this morning. Managed to shove it in my bag before my pops could see,” Mike smirked, bringing his bag around and lowering the zip to show the contents. Among the old wrappers, worn notebook and cracked tablet, Josh saw the fabled product they had been saving up for. The protein powder tub with the infamous M.A.S.S. Inc logo stamped across it. The image of the flexing powerlifter of a man practically smirking back at Josh, almost taunting the freshman with what was promised within.

“Dude, we’re finally gonna get huge!” Josh laughed as Mike closed his bag back up. Ever since the two were teenagers and saw the news of huge men growing from M.A.S.S. Inc’s products, they had been saving up every loose penny and bill for a chance to get the promised mixture. And no sooner than when they both turned eighteen did they get to actually buying their ticket to gargantuan mass and size. All it would take is one spoonful and they would join the epsilon of size they’ve fantasised and lusted for years for.

But before either student could go over their plans, even the brief one of sneaking to the bathroom together, their head lecturer called out to them.

“Mr. Richards. Mr. Collins. We’re waiting for you.” The old man called out to them, earning a startled jump from the two freshmen, and a snide laugh from the rest of their group.

“S-Sorry Dr. Simmons. We were just… taking in the room?” Josh laughed as he and Mike jogged back up to the group. It wasn’t entirely a lie since the room they were in overlooked a large tank of water, reminding the two students more of an olympic pool than a system for water filtering.

“Well then, you better listen if you want to understand this all.” Dr. Simmons said, shaking his head as he looked back at the tour guide. The professional seemed undeterred by the interruption as he went to explain the mechanics behind the systems. Meanwhile, Josh and Mike came back to the group proper, at least no longer the focus after their absence had been noticed. Moving along the railed off path beside the expanse of water.

“I mean, it is kind of small,” Josh said, blushing once the group turned over at him and realising he didn’t whisper that. “Like, It is huge water. But it doesn't look enough for a whole town.”

“That is correct,” The tour guide said, a smile on his face as he seemed to decide to show mercy for Josh’s faux pas, “Whilst this pool is a part of the town’s water supply. It is connected to an array of separate cisterns and reservoirs. We usually have this pool to help test and examine. More of a sample size than needing to test the entire drinking water for any contaminants.”

“Whoa that is cool.” Mike said, leaning over the railing as he looked over the pool of water.

“Yes it is. Though, if you can stop leaning over the-”

*SPLASH*

The guide’s warning was cut off. Mike only let out a surprised yelp before he fell over the railing. Landing into the expansive pool with a splash. The group exclaimed and shocked, with several commenting.

“Mr. Collins, you were warned!”

“Told you one of the idiots would fall in.”

“Shouldn’t have bet against stupid.”

“Gross, we’re gonna drink that!”

“One person falling in won’t make the water undrinkable. There are plenty of safeguards in place.”

Whilst the group was going hectic, either laughing or shaking their heads, the more observant researchers and Josh noticed a slight tinge of colour spreading out. And how the shadow of the submerged Mike seemed to be… growing…

“Did he have anything in his bag?” The tour guide asked, a pleasant mask of politeness gone as his voice cracked. He got his answer as the open and empty M.A.S.S. Inc tub bobbed up to the surface before Mike surfaced too.

Only, it wasn’t the skinny Mike that fell in. Instead, a swollen whale of a man breached the water surface. Scraps of clothing falling off the rolling fat rolls, swelling out more as cascading rivers flowed in between the bulging and overlapping rolls that could crush the smaller men.

“So… goooood…” The gargantuan man moaned out, a massive mitt of a hand groping the undulating mountain of fat that was his belly. His deep voice rumbling through the shrinking room with the group scattering from the bloating megachub man. Leaving the swelling Mike as he swelled and grew more and more with every heavy breath he took.

All except Josh, who watched his friend and crush obtain the size they have coveted for so long. With a hard on stretching the front of his pants, Josh rushed to leap over the dividing railing, briefly landing on the immense waterbed mountain that was Mike's belly, before sinking into the water. The powder’s effects hit him as his body warmed up and began to grow. Swelling more and more as the powder mixed more into the town’s water supply.

“Shit. Running low on water.”

It had been almost a week since the incident at the water plant and the town of Adiprose River had been changed forever. For many in the town, the first signs something was amiss was the water in the pipes sputtering before coming out with an almost earth scent, or how many men who drank or touched the water felt bigger and needing more.

Though what really told everyone something happened was when the plant exploded as two immensely fat men outgrew the infrastructure, their bloated and fat bodies wobbling freely as they embraced and kissed. The air rumbling with the dense belches and farts.

Even now, Conner could still hear the megaton men moaning for more, their mountain sized blubbery bodies having taken up the acres of land the water plant had been on. Their rolling fat hills visibly to most passing planes. Albeit, their heavy gas caused many to avoid the region.

Whilst the government with representatives from some out of town company helped to evacuate most people. However, almost all the men were left with claims of being due to lack of urgency or being ‘low priority’.

“They just want to watch us get fat.” Conner grumbled to himself, turning his gaze off the dwindling bottled water supply as he looked out to his street. Wincing as the ground shaking he heard last night confirmed another man drank the contaminated water. Across the street, his neighbour's house was gone. Instead, a giant fat man sat on the foundation. His undulating fat belly larger than the house had been covered in dense greying hair. His swollen arms rubbing and groping the blubber rolls as the bearded giant let out deep moans. The once scrawny Mr Samuels joined the horde of swollen blobby men that came from the contaminated waters. Whilst many who changed claimed it felt good, even wanting more, the remaining trapped men tried their best to resist and keep ‘normal’. Though the lack of water was making several give in. Conner himself had to watch as his dad, his brother, even his boyfriend joined the bloated whales in growth. Crushing cars as the waddled about, drinking and fucking with the sounds of belching breaking up the constant slapping of tectonic fat rolls.

Wondering if he could make a mad dash out, maybe break the quarantine imposed on town, Conner flinched as he felt a drop hit his face. Colour draining from his face as he looked up, the long trapped man realised the water pipe above his room had been leaking.

A groan escaped from his lips as the single drop that touched him sent a jolt through his body, his slim limbs starting to thicken out. The frantic thoughts running through his mind became dull as a persistent fog settled.

“More…” Conner moaned, moving towards the kitchen. Each step seeing him gradually swell out with plump fat. Hips and back widening as a bulging ass began to tear his shorts. His t-shirt tightening out over his bulging chest and bowling out belly. Yet, Conner didn’t focus on the arousing changes hitting him. Instead, he focused on getting to the sink, wrapping his lips around the long closed faucet before turning the taps open. The rush of water gradually filled his mouth as each desperate chug he took saw his body spurt more and more. Growing in a cascade of tearing clothes and crushing wood, unable to stop the avalanche of blubber that erupted out of what had once been mild Conner.

His fat hands tearing the pipes out as he craved more and more. EVen as his truck sized ass smashed through walls. His massive thighs crushed what furniture remained. His mountainous back and bloated shoulders breaching through the ceiling. Conner just kept drinking more and more and more.

… until the pipe gave him no more.

Sitting back with a deep thud, Conner let out a booming belch. The wobbling man panting as he took in what happened. The once trim and small body he worked to keep fit gone. Instead his multi ton blubbered form replaced it. Giving his impressive chest a squeeze, looking over to his rolling belly swelling out past where his outstretched feet laid.

… he wanted more of that stuff.
