You are what you fantasize
Have you ever been told that if you do/eat something too much, you'll become it?
Evan, age twenty one, sat at his desk. His tablet on his lap, he was doodling a picture of a large nude pig man devouring hamburgers, while his erection pressed against his belly. Evan's own erection was pressing against his tablet.
This wasn't the first time Evan has drawn this pigman. In fact, it was his favorite thing to draw. He loved putting the obese male in various situations, ranging from reading a book or sleeping, to eating, and even having sex.
It wasn't just drawing. He'd write stories, roleplay, anything he could put the character in, he would. He was so proud of his work, he just loved showing him off.
Naturally, he's also engaged in various sexual fantasies involving him. Ever since he dreamed about this character when he was sixteen, he's become almost obsessed with him.
His friends would often joke with him, saying that one day he'll wake up and look just like the character, or that one day the pig would become real and see all the things he does with him.
He was working on a particularly detailed part of the image when his stomach grumbled. Getting up, he made his way to the kitchen, where he heard someone rustling around. His roommate was at work, so he grabbed an umbrella from the coat closet and snuck through the door.
He was greeted by a large rear end covered in brown fur, and clad in a pair of underpants that were at or certainly near their limit. The owner of said buttocks was head first in the refrigerator, although it seemed more like he was rearranging the stuff, rather than actually eating anything if his moments were any indications.
"Uh, hey!" Evan said, attempting to sound threatening. "Who are you and what are you doing in my kitchen?"
The mystery person straightened up and turned around, nearly bowling Evan over with his bulk. Even though he missed, Evan nearly fell over anyway, though from shock.
It was him. The pigman that Evan drew all the time.
"Y-you..." Evan said, his throat drying up.
"Yo." The huge beastman said, casually. "What's up, Evan."
When Evan could only gape uselessly, the male sighed. "Okay, I'm sure this is a big shock for you. Trust me, going from a two dimensional character to a living, breathing three dimensional character isn't all that easy for me."
"You..." Evan repeated.
"Yes, me." The Pigman said. "And if you're wondering, my name is Evan as well."
"Evan?"
"Well, you did create me to live through. So its natural that I'd have your name." He shrugged. "Also whenever you write or do RPs you use your name,so at some point, it became mine too. I don't pretend like I know how the universe works."
"W-what do you want from me?" Evan the human said, still trying to wrap his mind around all this. It was way too meta for him.
"Well, you know how all your friends said that if you talked about me too much, I'd show up? Thanks for that."
"You mean..."
"Basically."
"So then...?"
Evan the pig grinned, reading Evan the human's mind. "If it helps any, I am rather handsome, and you're fairly good at sex scenes, so its not like I'm all that vanilla."
Evan the human resumed gaping uselessly, though his eyes were now focused on Evan the Pig's now bulging crotch.
"Oh yeah. Thanks for giving me a huge dick, too." Evan the pig said. He removed his briefs, showing Evan the human's work in three dimensions.
"Come on, you know you want me. I've been in your head."
Evan the human made a few sputtering noises, and regained his composure. "Well yes, but..."
"You didn't expect a fat, horny, beastman to show up in your kitchen and propose sex?"
"Well, yeah."
Before the conversation could continue, Evan the pig grabbed Evan the human's shirt and tore it off, then did the same to his pants and underwear, leaving the kid in the nude as well. He reached for Evan the human's scrotum and began to massage it until he was hard.
Evan the human climbed on top of Evan the pig, who lay on the kitchen floor, and began to rub Evan the pigs gut and play with his nipples, as his dick rubbed against his furry stomach. He continued to fondle and rub Evan the pig, working his way down, before reaching Evan the pig's rock hard cock, at which point Evan the pig reversed their positions, and sat on top of Evan the human, his enormous size dwarfing him.
"By the way, I should mention that your habit of exaggerating how much cum someone can blow has made me quite the geyser." Evan the pig told the human, lowering him so that his cock was inside the human's mouth. As Evan the human began to suck, he also massaged Evan the Pig's gut, unable to keep his hands off of it.
Meanwhile, Evan the pig rubbed on Evan the human, feeling the human's dick on the underside of his buttocks.
They came simultaneously, though Evan the human shot a much smaller load than the one that Evan the pig was making him drink.
It felt like minutes passed, before Evan the pig finally let up on Evan the human, slumping back onto his ass, panting.
Evan the human remained lying on the floor, equally out of breath. His mind was racing, and he was still on the euphoria of his orgasm.
Evan the pig quickly recovered, towering over Evan the human. "You know, I didn't just come here to do you. As fun as that was."
Evan the human shot him a puzzled look.
"Your friends also told you that if you thought about me to much, you'd turn into me. So guess what I'm gonna do to you now?"
A billion and one options flew threw the human's mind, each one more twisted than the last.
Evan the pig made a face. "Really? What is the whole reason you came out here in the first place?"
"I was hungry..." the humans voice trailed off as he realized what was coming next.
His mind flashed to the unfinished picture on his computer right now. The one with--
"All the hamburgers. That's right." Evan the pig said aloud. Immediately, they were surrounded by hamburgers, along with a variety of other foods. Evan the pigman grabbed one, took Evan the humans head, and shoved the hamburger in his mouth.
Soon after, another and another, and even more followed. Even as the hamburgers were thrown into Evan the human's growing stomach, the amount of remaining food was staggering.
With each bite, Evan the human got fatter, taller, hairier, and began to sprout a tail, his ears became more porcine, his nose became a snout, and his cock grew to match Evan the pigs. By the time half the food was gone, Evan the human was eating it all himself. He didn't notice Evan the pig becoming transparent and fading away until he had eaten all the food, sitting naked and overstuffed in his kitchen.
"Woah, what is happening to you?" Evan the human-now-pig asked.
"I'm done here. You've become me, so now my job is complete. Enjoy your life now, Evan. I'm sure it will be great."
Evan the pig vanished, and Evan the once human stood up. The kitchen was back to normal, his clothes were nowhere to be found, and all traces of what just happened were gone as well.
Evan heard the front door unlock and he froze. How the hell was he gonna explain this to his roommate?
Except, his roommate seemed totally unfazed by the obese, naked, beastman standing in the kitchen.
"Hey Evan. Sorry I'm late." His roommate said cheerfully. "I picked up some burgers on my way home. I know they're your favorite."
"Uh, thanks man. I had burgers for lunch, though."
His roommate laughed. "Oh really? Sorry about that."
Evan thought a bit. "Well, either way, no sense in wasting food, right?"
"You aren't mad?"
"Nah. Like you said, they're my favorite." He headed in the direction of his room. "I've gotta take care of some stuff I left on in my room. I'll be right back."
"Okay."
Evan took a look in his room. His computer was off, and his tablet, though several sizes bigger, was neatly on his desk.
The pictures in his room had all been changed, or rather, they had always been that way? Every photo of Evan the human was replaced with Evan the pig, the other subjects having changed to match the new life he lived. His parents were unchanged, which he took to mean that he was most likely adopted as a child. Pictures of him as a child, (or was it piglet?), a chubby teenager, a young man who was taller than his parents, and finally him at high school graduation solidified the fact that his roommate wasn't the only one who was used to Evan the pig wandering around.
Curious, he booted up his computer and checked his social networks. A quick scroll of his timeline showed that everything save for his species was basically the same.
"One one hand, I suppose that's fine, but what does this say about my character creativity skills...?" He asked himself flatly.
Shutting the computer off again, he made his way back out to the front room, wondering if reality tv in this universe was any better now.
He was also looking forward to those hamburgers.
