Upgrades People, Upgrades (TG/Yassification)

    Finn sat down at his computer and sighed. His entire feed was filled with shitty ai slop content. As an inspiring artist, Finn absolutely hated anything Ai related, art, videos, music. It just all was souless and hurt creators like himself. Finn tried his best to get back to drawing, but he just couldn't focus. So he want back into his feed, complaining about any ai content he saw. Then he saw it. Some sort of ai girl singing and dancing. Finn was livid! People were actually hyped to see an Ai anime girl sing and dance!? How could people actually fall for that?! Finley couldn't take it anymore and shut off his drawing pad for the day. He needed some air. 

    On his walk, Finn shoved his hands into his pockets and put in his earbuds. Some music would calm him down. He put on some random playlist he found and began his destress walk. It was nice, at least for a while. Then everything came crashing down. First, he saw someone wearing a shirt of that dumb ai singer Miku! Then one of her songs began playing on the playlist! Cursing Finn rushed home in rage. There was only one person that Finn could talk to about all of this, his roommate Andrew. 

"Andrew you there?" Finn asked through the door to his roommates, room. 

"Yep, what's up Finn?" Andrew replied back. 

"I... need to vent" Finn blushed. He didn't want to be a bother, especially to his crush. But that was another matter. 

"Sure, sure, come on in." Finn did so, gently opening the door to Andrew's room. He was sitting at his desk, clearly writing something. Finn sat down on the bed, even if he wished to sit on Andrew's lap. "So Finn what's bothering you."

Finn sighed deeply. "All this stupid Ai shit! I mean sure the Ai art and cringe videos were something. But now there's this anime singer girl!" 

"Wait you mean Hatsune Miku?" Andrew questioned. "Dude she's been around for years now" 

"Wait really? Still she's Ai and is taking attention away from real artists!" Finn vented his feelings. 

"Bro Hatsune Miku is harmless. She's a silly meme nothing more." Andrew explained, pulling up various Miku memes on his computer. 

"Harmless!? She's literally doing concerts and stuff! I knew you wouldn't understand!" Finley threw up his arms and stormed out of Andrew's room, leaving Andrew quite confused. But Andrew had an idea, that would maybe help Finn mellow out, and not be so angry at a truly harmless Vocaloid singer. So he began typing up a storm, planning out a harmless prank. 

Finn groaned and pouted in his room. Why couldn't Andrew understand!? So Finn got on his computer, seeing a discord notification from Andrew. Opening it, Finn was blinded as the screen turned a bright light blue color! Finn stumbled about his room, blinded by the light. When Finn opened his eyes, vision returning, he was looking at his mirror, and well, something was off. His dull, brown eyes were now a sparkling blueish green! "What the hell...?" As Finn looked into the mirror he started changing more! His height dipped down to 5'7, skin becoming smooth, creamy even, with little hair or blemishes. Finn's dyed green hair grew out in long, silky locks, the hair dye vanishing for his natural sandy blonde color, to then be taken over by a new, color, the same greenish-blue as his eyes. The hair almost touched the floor with the sheer amount there was. Finn tried to fight it, to no avail. That'd be a bitch to comb and wash. Finn's face started shifting, brows thinning, and lashes growing out, to perfectly frame Finn's anime looking eyes. It was kinda freaky to see in real life, but there it was. Finn's nose shrunk down some, and lips puffed slightly, just ever so slightly. His neck slimmed, voice becoming feminine and weird sounding, like it was... no... NO! Finn's voice now sounded like some kind of Ai! 

"Whyyyyy!" Finn cried out in his new feminine, sing song voice. Finn's shoulders narrowed down, arms thinning out, losing pudge. Hands shrank down, Finn watching as each digit slimmed, before his nails grew out in length, painted the same blueish-green color as his eyes and hair. Moaning a bit, Finn's flat chest began to protrude outwards, Finn panting and gasping as he grew some small breasts. Nothing spectacular, but breasts all the same. Finn poked one curiously, watching it jiggle slightly. Finn's waist pinched inwards, his pudgy stomach losing weight as his stomach flattened drastically down. Finn's hips widened ever so slightly, his butt going from lumpy to perky and cute. With his thighs just barely thickening, Finn felt his cock and balls quiver before retreating back into him with no fanfare. A tight pair of lips were now in their place. As quickly as the first one, there was another flash, and Finn blinked his eyes again, looking in the mirror he saw that, he was wearing that outfit Hatsune Miku wore! From head to toe he looked exactly like Miku... 

"Fucking Andrew did this I bet!" Finn stomped his foot. "He knew I hated this character and still, he made me her!" Finn decided to give Andrew a proper chewing out, so he stormed out of his room, his twintails flowing behind his quick movements. 

Without even knocking Finn stormed into Andrew's room! "Change me back dammit!" 

"Woah woah calm down!" Andrew put up his hands defensively. "Oh and nice Miku cosplay by the way"

"Its not a cosplay! Ive become Miku!" Finn tugged at his now long twintails to prove the point. 

"Wait... huh?" Andrew was quite confused about the ordeal. 

"You did this! Change me back!" Finn spat. 

"I didn't do that! No way!" Was Andrew going to deny it? Even now? 

"You totally did! You sent me something that changed me into this!" 

Andrew sighed, "Finn all I did was send you a funny Miku video. How would that reasonably be able to transform your entire body and clothes into Mikus?" Andrew stood up. "Just follow me" 

Finn and Andrew walked over to Finns room, Andrew motioning towards Finns computer to show that, all there was was a pretty dumb Miku video meme. "See? That's it Finn. Nothing more." 

"Well that doesn't explain why I'm suddenly an anime chick!" Finn pouted. Suddenly however there was a flash on the screen! Both Andrew and Finn leaned in and looked at the screen:

"Initiating Upgrade: File size increased from 128 GB to 256 GB!" the voice sounded like a text to speech. 

"Well that's odd right Finn?" Andrew turned to see Finn trembling a bit. 

"H-Help! I feel different!" Finn panicked, looking down at his new breasts, to see they were growing in size! "My boobies!" Finn moaned, his ass growing up a little bit, his waist narrowing a tiny bit more, and his hips jutting out just ever so slightly! 

"You weren't lying holy shit!" Andrew couldn't believe what he was seeing, but there it was, in front of him. In real time Finn was becoming curvier. But as quickly as it began, Finn stopped changing. "I-Is that it?" Andrew asked as Finn was left panting a bit. 

"I-I think so, for now at least..." Finn collapsed on his bed. "This is so dumb! Why'd it have to happen to me!" 

"No clue, but I'll start looking into fixing this okay?" Andrew said, putting a comforting hand on Finn's shoulder, making Finn blush from the touch, and feel an alien feeling down there. Andrew went back to his room, Finn's head was in a rush of new feelings. Quietly closing the door to his own room, Finn carefully reached under his skirt and brushed a finger over his new slit! Finn almost screamed out, but luckily covered his mouth in time. The next brush was just as pleasurable, than the last, and after so many satisfying brushes of a finger on his lower lips, Finn came, staining his sheets, and screaming into his small hand. 

Several days passed to not much avail. Andrew searched far and wide as to what caused his friend to suddenly become a woman. Finn tried to stay inside as much as possible, but even he had to go out from time to time, getting weird looks, and people wanting selfies with the Miku cosplayer. It was rough, but at least Andrew was there. Finn felt his feelings for his roommate grow deeper and deeper with each passing day. 

Finn was jolted from his daydream to a sharp knock on his bedroom door. "Finn you up?" It was Andrew. Finn got up and opened the door. 

"I am now" Finn posed awkwardly, trying to show off to Andrew. Andrew entered the room and sat at Finn's desk. 

"I think I figured it out what changed you. It was a furry hacker" Andrew said typing and looking through Finn's files. 

"Isn't saying a furry hacker just synonymous? They're all the same" 

"True" Andrew nodded in agreement. "Anyways, some sort of hacker put a bug in your PC. I think I can get it out... oh crap I misclicked." 

"You what!?" Finn was followed up by that eerie text to speech voice

"Initiating Upgrade: File size increased from 256 GB to 512 GB!" the text to speech voice stated plainly. Andrew turned to Finn and gave him a sorry look as Finn began to feel pressure build up within him. Finn let out another lewd moan, his lips plumping up significantly over their original size. Make up caked Finn's face, heavy around the eyes, and a nice coat of lipstick on his lips. Finn's dress shortened and tightened up, as his thighs thickened another size, and his butt jiggled forth in size and status. Finn's nails grew out slightly, now painted a pretty pink colour. Then Finn felt a large rumbling, centered at his chest. 

"Not any biggerrrrrr!" Finn moaned out as his chest began to surge forth, fat and flesh stretching out Finn's chest not just one, but several cup sizes. Finn grabbed at his chest, "Sthaaap growing!," trying to push the surging fat back, to no avail. 

"You alright Finn?" Andrew reached out to his friend. 

"Yeah... I like... err think so" Finn was still in a daze from the drastic changes. "I just need a minute or ten..." 

"Yeah I get it, im so sorry about this..." Andrew hugged Finn a bit. 

"Dont blame yourself, you just made a small mistake..." Finn hugged Andrew back tight, his body wanting the comfort, but at the same time, making Finn a mess of feelings. 

"Anyways I better get back to researching this. I got the file from the hacker on a thumb drive so I can analyze it." Andrew held up the stick drive. "If you need anything just ask okay?" 

Finn nodded and Andrew exited the room. Finn just spent the rest of the day groping his new larger tits and thicker ass. Every inch of his body felt good, and he couldn't wait for Andrew to take him, bend him over and- "No! Fuck..." Finn shot up, these feelings were so complex, and Finn felt like he was seemingly in a horny daze, some sort of fog in his mind. Finn's hand reached down to his lower lips when the computer text to speech came back on. 

"Tell your friend to stop trying to stop my plans!" the computer spoke. Finn got up and walked over to his PC, wincing a bit at the jiggle in his assets. 

"What do you mean?!" Finn demanded. 

"If you do not stop him, I'll also turn him into a Miku!" the computer, even with a text to speech voice, was full of malice. 

"You wouldn't!?" Finn was now worried. 

"I yes I would. I love turning people into Mikus!" the computer chimed happily. 

"Why... why do this to me? To others?" Finn wanted answers, who wouldn't. 

"Oh that's rather simple. Its funny. Watching someone slowly morph into Miku. Plus with my elite hacker program, I can even yassify them! It's like even doubly funny" The hacker was really that sick? That depraved. "So far I've made about twenty different people Mikus. Its been at random actually. I don't target specific people, except that one guy who married Miku a ways back. But with you, my program is almost perfected. Maybe once it is I can go after celebrities, and wealthy businessmen, and politicians! The world is my oyster!" 

"That's it? Its funny to you?!" Finn was about to blow a gasket. 

"Aww look how cute you look when you're angry." the computer voice let out a robotic giggle. "Now go destroy that thumb drive and I'll leave you alone!" 

Finn didn't want to.. but at the same time he didn't want his roommate to suffer the same fate. So he agreed, exiting his room. 

The computer laughed, ""Initiating Final Upgrade: File size increased from 512 GB to 1 TB!" 

Finn paused at the door about to knock when he began to feel that same pressure and pleasure. He knew he was being updated. The final time! Finn let out a moan, his lips plumping up into massive cock suckers, always pouty and hard to close fully, seemingly in a permanent 'O' shape. Heavy pink eyeshadow adorned his eyes, now a permanent feature of his face. The same went for the pink lipstick that coated Finn's lips. Finn's face looked like it was in a permanent blush, Finn's mind being drowned under a constant horny daze and fog, limiting his intelligence, while boosting the feeling's Finn had for Andrew. Finn's nails grew out several inches long, a gaudy pink color. Finn's chest exploded outwards, into tits well larger than his head, forcing his top to become an ill-fitting crop top, exposing his waist, which in turn, turned inwards. His hips jutted outwards further, flesh and fat rushing into his butt as it grew into a wobbly mess, along with tree trunk thighs. Finn's skirt was now so short, it showed off his blueish-green stripped panties, which were so incredibly wedged between Finn's fat ass cheeks. 

"Final update complete!" The computer and Finn said simultaneously. Finn, what was left of him was now a yassified, bimbo slut. With confidence she opened the door to Andrew's room, her body jiggling tightly in her outfit. 

Andrew turned around in his chair, "Oh hey Fi- oh fuck! What happened!?" Andrew rushed up towards Finn. 

"Oh like nothing much~" Finn licked her lips. "Im like totally perfect now" 

"Finn that hacker is messing with your mind! You gotta fight it!" Andrew pleaded with his friend. But Finn was gone. No, only Miku remained. Miku just giggled. 

"Why fight it when it feels like totes amazeballs~!" Miku pushed Andrew towards his desk, clawing into him as she began deeply kissing him. She needed Andrew, and that's what she'd do. Andrew fell back into his computer chair, Miku straddling his lap, barraging her man in kissing, leaving lipstick print after lipstick print. With a devious grin, Miku swiped the thumb stick, sticking it between her cleavage as Andrew was rather... distracted by kisses. Andrew's resistance quickly faded, and Miku could feel why. He was growing horny and very hard! 

"Mmm Andy~ You're like so hard right now~" Miku rubbed the bulge through his pants. "Let's have some fun, and no complaints~" Miku pressed a finger to Andrew's lips. Miku giggled and undid Andrew's pants, getting her prize out, then with some effort, wiggling her tight panties down. And with no words from either party, Miku plopped herself down onto his cock, both getting into a rhythm of pumps and moans and writhing. 

The hacker was never heard from again. Andrew gave off the search after a while, especially with Miku there to convince him otherwise in increasingly pleasurable ways. Eventually the hacker would get caught, after attempting to change the Prime Minister of Tajikistan into Miku for some reason. But with no cure, all her targets remained yassified, bimbofied Mikus. At least for Andrew and Miku, there weren't any real complaints, mostly because both were too busy fucking like bunnies to say otherwise. 

The End. <3
