Hey guys! I'm here with a small story that started as sort of exercise.

Those of you who watch me are probably used to my very slow-paced writing style. Well, this story is an exercise to try a very fast-paced action-packed style. Don't hesitate to tell me if you like this faster style.

Side note: I plan on trying to do a sort of writing stream soon. I'd share a google doc where I write the story, and interact with people over my discord server for suggestions or comments on the writing. Leave a comment if you would be interested in watching/participating!

Now, on to the story. Hope you guys enjoy! (Check the tags, it's a very kinky story)


A small alien arose from the debris of the crater made by the meteor he rode until moments ago. It had the form of a small blue blob of goo. Still somewhat stunned by the impact and crash landing, it began scanning its surroundings. It had landed in the middle of a forest. Dozens of small creatures were drawn by curiosity to the impact zone. Any of them would do for what the alien had planned. It was feeling hungry.

A mouse came close to the green goo. A little too close, even. The alien jumped at it, ensnaring it inside his own body and began the process of assimilation. In a matter of a few seconds, its prey had dissolved and the goo was now significantly bigger than earlier. It took on the form of the creature it consumed, finding that its legs were a lot more practical than its previous body. Thanks to this new form, it scurried away in search of another meal.

The alien consumed all it found. Several creatures went through the same fate as the mouse from earlier: a squirrel, a cat, a bird. It even tried to devour an old tree stump, which felt bland. By this point, it had already reached the size of a small dog.

A tennis ball landed right next to the pile of goo. Curious at the behaviour of the small object, the alien approached. Then, a small dog leapt out of a nearby shrub. The animal came close to the goo creature, sniffing it as if to determine if this was a friend or not. The alien didn't hesitate, it literally exploded in a wave of blue goo that immediately surrounded the dog, leaving the poor thing no chance of escape. As it began assimilating the creature, its intelligence grew. The dog he consumed had a name, "Remy." The memories and feelings of the dog flooded its mind. Images of the dog's master flashed in its mind.

A voice echoed in the forest. It called the dog's name. The alien turned its head towards the source, finding that the memories of the dog it had assimilated had a great influence on its mind. Instinctively, it took on the shape of his latest meal, a one foot tall dog. Happiness flooded his brain. Happiness, but also hunger. He dashed to where the voice came from.

Upon finding its master, a small three foot tall fennec fox wearing a t-shirt and shorts, Remy jumped in his arms. The two of them fell on the ground, with the alien standing over his master. It felt compelled to lick the fennec's face while wagging his tail. It could not comprehend the fear in its master's eyes. Remy liquefied into goo, wholly enveloping the fox, hoping to explain his love. And his hunger too. The small male was assimilated quickly, making the alien gain a lot of mass. Along with that, it also became a lot more intelligent, learning a lot about the world he had landed on. The blue goo reformed into an almost perfect copy of the fennec fox. He learned a lot by scanning his latest prey's memories. The most prevalent thing he found were images of giant people having sex with each other. Remy knew it was just fantasy, but these pictures popping in his head made his cock grow to a full erection, which was a meagre and disappointingly small two inches. Driven by curiosity, the alien brought his hand to his dick and began masturbating. It didn't take him long to reach orgasm. The first climax he had ever experienced. It felt almost as good as consuming prey. His cock shot a few spurts of cum, which left him wanting for more. And more he would get. Now, he had two goals. Sate his hunger and satisfy his newfound libido.

Remy roamed the forest in search for more prey to consume and grow from. He would also have to do something about his cock size, because two inches were just not enough. His ears picked on a nearby snoring. He headed to the place and found a campsite. There was a single tent from which the noises came from. Grinning, he closed in on his next target. His cock was already standing at full mast, throbbing in anticipation. He stepped inside the tent and slipped underneath the sleeping bag. Upon finding his nose in front of the stranger's crotch, he tore the underwear open and began ravenously lapping at the sheath. The cock arose from the sheath, it was decorated with many barbs at the tip that were tickling his palate. The man began moaning in his sleep as he was getting a blowjob from the alien. Remy felt two hands grab his head and lock it in place, and cum began rushing in his maw. He eagerly drank the few spurts, finding the taste to be oddly exciting. When he was done drinking, he crawled towards his prey some more and began dissolving to envelop him in his gooey body. He assimilated the cat guy, trying to focus the mass he gained on his cock, though it didn't prove to be that effective. Still, he had gained a fair bit of muscle definition and height, standing at four feet and a half in height, with a five inch long cock that was now decorated with barbs all over the head. He became much larger with this last prey, but it was nowhere near enough for Remy.

The alien went back to the forest to find more prey. He stumbled upon a pair of joggers who were talking to each other and thus were oblivious to the predator closing in on them. Remy chose to go for the cheetah first, leaving the rabbit for later. The alien dashed at his next target, leaping and grabbing him before melting into goo to envelop the guy. The two joggers were startled by the sudden assault, and the rabbit immediately began sprinting as his friend was being consumed by blue goo. The assimilation took at most ten seconds, after which he stared at his growing body. He already reached to five feet now, with muscles visibly swelling. His cock - which hadn't gone down since he consumed the cat in the tent earlier - elongated and gained a few inches in width, the barbs decorating it were thickening and lengthening. Because his last meal was a cheetah, his leg muscles developed tremendously, which allowed Remy to catch up to the panicked bunny in no time. He pinned him under his weight and plunged his cock in the rabbit's hole, immediately reaching his climax. His dick shot rope after rope of cum inside his prey, and when finally the high of orgasm came down, he dissolved around the bunny to also assimilate him. When he was done, Remy stood on all fours and brought his hand to his lengthening cock, stroking it furiously until he came once more, coating the grass underneath him. The alien was now six feet tall and was very fit. His dick had reached a whole foot in length, bobbing in front of his top row of abdominals, and his balls were dangling heavily between his thighs.

Running after the rabbit brought Remy far from where he was earlier. He heard loud noises and cries nearby and, upon investigating, found two people. A huge six feet half muscular donkey was getting fucked by a five foot tall wolf. The alien almost drooled at the sight of the thick equine, and stealthily approached from behind. Upon getting right behind the wolf, he clasped his next target's mouth with his hands and shoved his whole foot long cock inside the lupine ass. An idea sparked in his mind, what if he used his goo in a more creative way? He forced the wolf's mouth open, dissolving his arm and forcing himself down his target's throat. Then, he forced his other arm, his head and the upper half of his torso inside the struggling wolf's maw. He began overtaking the wolf's body from the inside instead of from the outside like for his other prey. The poor lupine began growing, his lower body merging with the leftover goo from the alien, though his ass was still filled with the huge gooey cock. Having now overtaken the wolf's mind completely, Remy began changing their bodies slowly, merging them and growing bigger and bigger. The donkey turned to see what was happening, frightened by the image of his previously small partner becoming larger by the second. Remy used his newly stolen strength to pint he donkey on the ground, easily preventing him from escaping. The cock in the donkey's ass was swelling, growing, gaining large barbs, and Remy's balls were slapping heavily against the donkey's thighs with each thrust. When the merging and absorption was complete, the alien grew to a whopping six feet half, with his foot long cock buried in the donkey's ass. As he was about to cum, from his sheath exited an enormous six inch wide knot that he hurriedly shoved inside the donkey. He came hard, his sixteen inch dick throbbing and shooting seed, rope after rope of it. A whole minute passed with him cumming inside the donkey. Then, when he was done cumming, he liquefied his whole body and pushed his goo inside the donkey's ass. His prey's belly inflated comically large as the goo invaded his body. Just like for the wolf inside, Remy began overtaking his meal's body from the inside. He immediately began spreading the goo everywhere in his prey's body until he had completely overtaken it. As soon as he had claimed the donkey, his inflated belly deflated, spreading more goo all around the body. Seven feet tall already and he kept going. Seven and a half; his muscles were becoming huge. Eight feet; his frame was getting so thick. Eight feet and a half, and he stopped here. His cock throbbed hard, and began changing to take on all the best features of the beings he consumed until now. His equine penis lengthened, fattened, gained huge barbs all around the head, and grew a huge knot at the base. Unable to resist the temptation any further, Remy wrapped both hands around the enormous tool and began masturbating. From the two feet of cock erupted a white flood that flew high before splattering down on the ground. Remy was completely lost in his libido and hunger. He had gotten so much more than he had initially planned, but it still wasn't enough!

Remy, whose body was still mostly that of a donkey, began walking once more to find more prey. He was completely drunk on power. He ran through the forest, trampled over any tree or bush that stood in his way. He made it to a small cabin in which people were happily talking. Cries echoed as soon as the eyes of the people fell upon the giant alien running to them. Remy smashed the front door and part of the wall and eyed the inside. There was a chubby eight foot tall bear and two rodents - a squirrel and a rat - both three feet tall. He pinned the bear on the ground, fucking him raw, the two rodents cowering in fear in a corner of the room. As soon as he came, the bear started losing his shape and became blue goo that moved around Remy's body to beef him up even more. The size of that meal was so huge that he gained two and a half feet in height, reaching all the way to eleven feet tall. When he was done assimilating this last meal, he grabbed both the rodents, brought the rat to his mouth and opened wide, swallowing him whole; and brought the squirrel to the tip of his now three feet half cock, shoving him muzzle first down the slit of his cock. Both his throat and his cock bulged massively as his preys slid down inside him. One landed in his stomach, and the other in his balls, and they both were assimilated fast while the alien was masturbating again. To twelve feet he grew, then thirteen. His cock surged in length, reaching four feet and a half in length. The head was bobbing right in front of the base of his neck, so he leaned and lapped at his cock. His balls dropped to the ground between his knees, and he bucked his hips as he facefucked himself until he came. Remy drank the first two blasts, making his belly swell quite a bit, before he let go of his cock that began painting the whole cabin. A minute and a half later, the old wooden house was covered in spunk, and the donkey giant inside was huffing. More, he needed more! He stood up, crashing his head in the ceiling, making the whole building collapse.

Remy ran, excited to find new prey to gobble up. He reached into the shores of a lake, where he spotted a shark fisherman who was facing away from him. The alien stealthily closed in on his target and grabbed him. The shark struggled to no avail despite his immense build of eight feet of muscle. In the blink of an eye, he was impaled over a cock that was more than half of his height. From his belly, the giant shape of barbed-knotted-equine dick of the giant was protruding. Remy took almost all of it out of his prey before shoving it back inside equally fast. He reached another climax, unloading an immense load inside the shark. The fisherman's belly expanded, swelling with every blast of cum, becoming soon swollen enough that his overinflated skin grazed against the ground below. It coincided with the end of Remy's orgasm, so the donkey let himself liquefy to envelop his latest prey. In a split second, he assimilated the shark, becoming one with him. As he was reforming his body around the shark, he noticed an interesting feature of this meal's body. Instead of growing his cock even bigger, he grew both his cocks at once, the two of them reaching up to the top of his pectorals. He grew and gained the impossibly huge muscle definition of the fisherman, getting to fifteen feet in height and five and half with his cocks. His balls swelled, dangling heavily between his knees. And yet, he still wasn't satisfied!

On a nearby shore, Remy found two lizards sunbathing. A tall naga and a huge dragon. The two of them were oblivious to his presence, a fact that he used against them. He grabbed the naga first, forcing his mouth to stretch open and impaled him on his left dick. Then, before the dragon could even react, he pinned him on the ground and shoved his right cock in the reptile's ass. He fucked them both at the same time, revelling in the intoxicating feeling of having his two cocks buried inside other people. He kept on going faster and faster, soon unleashing yet another climax. Both reptiles began inflating, so much so that they both looked like overinflated balloons leaking cum from whichever hole wasn't filled by the alien's huge knots. He then proceeded to absorb them, growing even bigger and reaching twenty feet tall. His cocks were approaching eight feet in length and almost three in width.

Growing so little with each meal was not enough anymore for Remy. It was time to step up his game. He headed for the city, now, and planned on absorbing everything there.

Remy ran through the city, grabbing furs and shoving them wherever he felt like absorbing them. Grabbing a fox there, shoving him down his cock. Twenty one feet. Grabbing an alligator and gobbling him up. Twenty two. He even tried to use his new reptilian tail to grab prey that he then shoved down one of his gigantic cocks. Twenty three. There was no stopping him now. A bull was stepped on; instantly assimilated. Twenty four. Everything that got in his grasp ended up devoured. Twenty five feet. Remy picked a car and smashed it against his chest, forcing the vehicle to enter his chest, where it was dissolved and assimilated, making him surge in height to twenty seven feet tall. Of course, consuming vehicles wasn't as tasty and satisfying as consuming people, but it granted him height all the same. Therefore, he began stepping on cars, absorbing them through his feet, which then sent waves of growth through his legs and then spread to the rest of his body. Thirty feet already. His cocks were nonstop leaking pre over the streets. Remy lowered himself on all fours and began grinding his two towers of flesh between his pectorals and the street below. Any unfortunate soul that happened to be here at this moment was instantly devoured and assimilated. His arousal skyrocketed and he came. A white flood was unleashed on the city, like a tsunami. The whole city was in complete chaos, and Remy absolutely loved it all.

The blue goo alien then got an interesting idea, he severed his own arm and made it reform into a copy of himself. The copy wasn't as tall as he was, obviously, but it immediately began its own rampage, fucking everything it could and absorbing it to grow even bigger. Remy reformed his arm, which actually cost him some size, but it would become a valuable return on investment in the future. The crazed giant alien grabbed a particularly wide skyscraper and rammed both his cocks inside. Every piece of furniture, construction material, and people that were in the floors pierced by the giant dicks were instantly absorbed, making the tools grow bigger and thus grow into more floors that they consumed. The whole building collapsed onto him, and every piece of rubble that fell on his body splashed inside him to be absorbed and grow him. When he was done with this skyscraper, he was easily over fifty feet tall. And there were a lot more skyscrapers in the city! He severed both his arms again, creating more clones of himself that he sent to rampage through the city and collect size for him. Then, he cockslapped a building, devouring everything inside to regrow his arms. He severed his arms, and teabagged a huge house, his balls devouring it all to regrow his limbs again. Slowly but surely he created an army of himself that were completely destroying the city and absorbing anything in it.

Remy went to fuck several more skyscrapers himself, growing bigger and observing his clones while growing. He had grown to sixty feet tall again. He spotted a twenty feet tall gooey alien copy who was fucking a bus and a truck, one on each cock. Remy went to his next skyscraper, getting already to seventy feet tall admiring the way how a fifteen foot tall clone was shoving passersby inside his cocks, which had grown almost bigger than he was. He kept on fucking this giant skyscraper, growing to eighty feet tall and observing another copy of him who was ten feet tall was headbutting into buildings while absorbing everything. It gave him an idea, and he threw himself over a stadium, absorbing everything that was inside. He exploded into a goopy puddle upon landing, absorbing everything that got inside the goo, building, people, everything. When he reformed, he was well over a hundred feet tall and his cocks towered over his head, shooting cum in the most mind-boggling climax he experienced yet. It was utterly amazing and he loved it, but he wanted more, so much more!

His ascension was going so well, and the destruction of the city was soon complete. There weren't many things to absorb left, and spotting one of his clone in the middle of fucking another gave Remy an idea. He recalled all of them near himself and lied on his back before giving them all the order to start fucking him in any way possible. The clones obeyed eagerly. One of them shoved both his cocks inside his mouth, another began fucking his left cock and another fucked his right cock. Another clone shoved one of his cocks Remy's ass, and yet another clone fucked that clone with one of his dicks while fucking Remy with the other cock. It was a huge orgy with giant gooey monsters of all shapes and forms fucking each other like while beasts. Some of the clones merged back together, making their cocks swell to impossible sizes while inside other copies or inside Remy. While merging, one of them kept each pair of dicks from both the copies that merged, making him a quad-dicked god. Remy came again, shooting cum right inside the cocks of the two guys who were fucking his dicks and making their balls swell exponentially, which caused them to smash more things in the city and thus grow even bigger.

When his own orgasm was over, Remy began absorbing all his copies regardless of whether they had reached their climaxes. He absorbed the one facefucking him, growing to 300 feet. He absorbed the two that were fucking him, growing to 500 feet. Then, his cocks slurped the two that were fucking his slits, making him grow to 1000 feet. Upon absorbing the one who had four dicks, he gained the extra two for himself, making him a titanic mile tall four-cocked god. There was no clone left in the city, and there was no city left. However, there were other cities.

Remy stood up, took two steps forward and brought his paw up, looming over the next city. He crashed his paw down, absorbing everything underneath it. He grew half a mile from that, and was immediately brought to orgasm, his four cocks shooting cum in the clouds. He was now giant enough that all it took was one step to reach the next city. 2 miles tall. And only one step after that one. 3 miles tall. Every step he took made the whole country tremble. He dipped his tail in the ocean, absorbing a lot of the water and growing to ten miles. His cocks were shooting cum nonstop, his balls had become so large that he had to drag them behind himself, flattening anything behind him that he hadn't trampled on and thus, growing even more. He reached to 15 miles tall already. His head was in the clouds and he kept going. He didn't even need to look where he was stepping, his paws had gotten so large that he crushed several cities at once with every step. And if he missed something, his balls would finish the job. 25 miles tall. His steps were starting to make earthquakes, shaking the very planet. 35 miles tall. His cocks were now shooting cum into space. He kept on walking, smashing more and more of the continent with every step. 50 miles. His paw landed in an ocean that was instantly dried up and made him grow from absorbing the water and the oceanic wildlife. 150 miles tall.

There was no stopping Remy anymore now. It came to a point where the growth he was getting from absorbing things was making his paws and balls swell so much that they were instantly consuming anything they touched to grow bigger yet again. 300 miles tall. His balls were as large as he was, his cocks each thrice as long as he was and as thick as he was tall. 500 miles. His head was in space and kept getting higher. His two lower cocks were lengthening along the earth's crust and his two upper cocks were growing up in space, all four of them shooting cum in a neverending climax. 1000 miles. He tried grabbing his cocks, but all he could reach was the oversized knots. 1500 miles, and his balls were now as wide as the planet was. Which meant it was time. Remy melted in blue goo, enveloping the whole planet in his own being, and reforming himself around it. He didn't have enough mass to do so just yet, and thus sacrificed his dicks and balls momentarily so that he could have the planet in his belly. Then, the absorption began, and a single, huge cock began growing from his groin. It shot upwards hundreds of miles every second, quickly outgrowing Remy. His balls regrew too, soon reaching to their previous size of the planet he was devouring. In his growing craze, the alien aimed his dick at the moon and continued on digesting it without ever stopping. The moon was swallowed by the astronomical dick, sliding inside his slit, pulled towards Remy's balls by gravity.

As he was absorbing the moon and the planet, Remy reached the most intense orgasm he ever experienced. He kept on growing, enveloping new planets in his gooey body, and growing more and more. And he would keep on growing bigger and devouring everything until there was nothing left to swallow in the universe anymore.
