Jason ducked as a water glass went soaring across the living room to shatter against the wall behind him. "Babe.. it's a harmless fetish."
"Don't you 'babe' me." Lena shouted as she grabbed a lamp and hurled that at her boyfriend. Luckily Jason was nimble on his feet and that landed with a shatter a couple of feet away from him. "It's disgusting, and you're disgusting."
"Ba.. Lena. It's harmless porn, everyone looks at porn." Jason quickly grabbed up a bowl before Lena could get her hands on it. She punched him in the stomach instead, causing him to drop and break it anyway.
"Porn is fucking the pizza delivery guy! That was a horse guy ramming a giant cock up a dog!" Lena had caught Jason browsing his favorite furry porn site, and well, he didn't think she would take discovering his fetish that badly. He also wisely kept his mouth shut to not correct her that it was a fox not a dog. "And two guys?! I thought you were straight!"
"Bi.." Jason said, earning a slap across the face. "Damn it, Lena, I thought you would be more open about this.."
"Do you think about that while we're.." Lena didn't finish the question, but the fact Jason didn't answer gave her what she needed to know. She stormed off to the door of Jason's apartment. "We're done, Jason. I'm going to burn your crap at my place so don't expect it back."
"Lena, wait. Can we just talk when you've calmed down.." That was the wrong thing to say.
Lena's eyes flashed and she murmured something under her breath that did not sound like English, a bolt of some light flew from her hand and struck Jason right in the chest, sending him flying backwards. Luckily he landed on the sofa and not one of the many piles of broken glass or ceramic. "What...?" Jason doubled over. It felt like something was twisting his guts.
"Oh, there's my secret. I'm a witch. Let's see how you like your fetish now. Every time you cum, you're going to lose a little more of your humanity. But we need to start you off somewhere." Lena grinned an evil grin. "Good bye, Jason, go fuck yourself." And with that, she left, slamming the door behind her.
The twisting in Jason's gut turned into a burning sensation that seemed to settle in his crotch. What the fuck had she done. He quickly pushed down his shorts and briefs, letting his burning cock flop free. It stood completely rigid at its full six inches, but instead of its normal color the whole shaft and head was bright red, like his cock and only his cock was sunburned. Lifting his shirt a bit with one hand so he could keep a good view of his manhood, he reached out to take it in his other hand. He flinched away as if burned. It was scorching hot.
His heart was beating faster, and it seemed with every beat of his heart his cock pulsed. Was it getting bigger? No it couldn't be.. but no.. it was definitely getting a little bigger with each pulse. Pre dribbled from his slit and down his shaft, causing the red flesh to glisten. Longer and thicker with each passing second.
Then the weird shit happened. The mushroom head of his cock started to meld with the shaft, the middle bulging out thicker and thicker as the tip of his cock narrowed. Jason had seen enough furry porn to recognize the shape his cock was taking immediately as it came to a point. Two bulges formed at the base of his cock, one on either side, hard as the rest of his not eight inch rocket-shaped cock.
His balls felt heavy and swollen, and when he reached down to cup one he could feel they were distinctly larger, each about the size of a lemon, and more disconcertingly, they were much fuzzier than they were before. He couldn't seem them clearly, but it looked like a layer of short black hair had grown over them. His pubes were likewise turning to the same short black hair.. no.. it was fur. A diamond shaped patch of black fur around his swollen canine cock. Extra skin began to grow around the base of his cock, pulling it tighter against his stomach, the bulge of his not moving upwards a bit as his forming sheath pushed his cock to a slightly different location.
And all this time it continued to grow right past ten inches to an obscene twelve inch rod of doggy cock. Well, furry porn did tend to exaggerate, and it certainly fit his fetish. The heat pulsed one more time and he threw back his head, letting out a loud grown as he shot his cum straight up into the air. Some landed on him, some on the couch, quite a bit hit the wall. It was more that Jason had ever come in his life. It felt so good..
The heat subsided and Jason felt himself able to focus on something other than his cock. What had Lena said.. each time he came he'd lose a bit more of his humanity? Well, it seemed this first one was a freebie, or was just for his cock, because nothing else seemed to be happening. He lay on the couch for what seemed like forever, just trying to make sense of what happened. Eventually, his knot softened and his cock slipped back inside his sheath. Even hidden away there was no hiding what he had. His sheath was heavy and plump, and his balls would make an impressive bulge on there own...
What could he do? A doctor would turn him into a science experiment, and his furry pals would think he was just role playing. His roommate would be home soon, but that would have its own set of problems. Or he could wait, hope Lena calmed down and try to get her to undo what she did.
