It still hurt the following morning. Your bandaged hand gave a sharp pain, waking you. In a groggy daze you tried to fathom what would cause such agony, then the memories come back. You were taking the shortcut home from high school, going through the nearby wooded area and there was a rustle nearby, with a yelp. It sounded like someone in pain, so you called out and made your way over, only to find it wasn’t a person. A huge orange fox had its front paw caught in a bear trap. You were surprised that the trap hadn’t ripped the fox’s paw clean off, given the heavy metal it appeared to be made of and glimmer denoting its sharpness. However, this seemed to be more than a mere fox, it was bigger than an alsation!
However, you’ve always had a thing for animals, and can’t stand them being in pain. Perhaps if you could open the trap, it might be able to survive with just a limp for a bit. The fox yipped as it spotted you, seemingly defensive. You tried to show that you were there to help, and eventually approached. It seemed to be submissive, cowering a little as you looked over the trap and found the mechanism to unlock it. Carefully putting your hands in harm’s reach you managed to disarm it and the trap opened. 
The fox moved its leg out and you saw that it was uninjured. No blood, no breaks, it seemed fine. That’s when it bit you. You recall it didn’t hurt that much, but it did break the skin. It vanished into the forest whilst you were startled, but you remember its powerful golden eyes gazing at you when it bit you. Either way, your trip home was followed by a quick call to the local doctor to get it checked out, and nothing seemed to come back from the initial tests.


However you are sure that the pain is from that bite. You called out to see if your mom was around, but as your vision cleared you saw your alarm clock hadn’t gone off. You had missed most of school already and your mom would be working late tonight. You wonder if she would’ve tried to wake you, but that could wait until you found painkillers. Staggering out of bed you make it to the bathroom and open the medicine cabinet, grabbing a couple of painkillers and running the tap for some cold water. Closing the cabinet you can see yourself.
You feel like it might be a trick of the light, or the wooziness, but it almost looked like you had abs. In your seventeen years of life, you’d never been considered super fit, but not unhealthy either. Yet here in your vision you could see that your chest and abs were looking somewhat toned. Maybe this last year’s PE had been working for you.
Regardless you down the painkillers and gulp down the water. You hadn’t realised how parched you were until now. Maybe it was water dehydration that made you have that definition, you remember hearing some movie actors use it to get buff. What you didn’t pick up on when you left the bathroom was the faint gold flecks in your eyes.


Given you had already missed most of the school day, and it was a Friday, you spent the remainder of the day watching TV and relaxing. The pain subsided after a few minutes and it was all but forgotten. You found your attention drawn to a documentary, a wildlife show on foxes. It was a bit of a blur, but your mind was focused on all the information coming in, looking at the foxes on the screen in their natural habitat, then an image of those golden eyes flickered in front of you.
Your heart was racing and breathing became heavy. Your brain was trying to process something, and came back with it being some sort of PTSD. That was enough TV for the evening, you defrost a pizza and eat it in your bedroom. You fall asleep shortly afterwards, still a couple of slices uneaten.


The pain woke you up again. However, your senses were sharp. The room was dark, but your vision felt somewhat heightened, letting you see in perfect clarity. Your clock showed midnight as you reached for your phone. Then you saw the change. Your arm had been replaced with a long muscular one, the arm coated in thick orange hair until the forearm, where it and your hand seem to have been coated in black fur. Your fingers were still in the expected configuration, but there were claws where there were nails. You gasped as you brought your hand to your mouth, as if to stop a scream that didn’t come. It touched an unfamiliar face, finding a pronounced snout with a wet black nose. Your eyes had blanked it out, but there was definitely a fox’s muzzle there.
Your brain was yelling to call for mom for help, but there was another voice deeper down, something more primal, telling you to enjoy it. That voice was getting louder by the second as it seemed to be fighting with your initial thought. You get to your feet and the tips of your vulpine ears brush the ceiling. You were almost six feet tall this morning, and your ceiling is around eight feet in height. You put on two feet of height! You looked at the door to your room and it looked too small for you now, but your big clawed hand managed to turn the handle and you squat beneath to leave, trying to get to the bathroom again. Then you realised your shoulders were much broader. If you thought you had put on muscles that morning, it paled in comparison to now. You were going to look down, but your muzzle met a shelf of pecs; huge, muscled pecs coated with white fur and bordered by the same orange as your upper arms.
Somehow getting to the bathroom you finally got a decent sized mirror to gaze in. Somehow, your body had become a huge studly fox-person hybrid. Your physicality was still humanoid, but covered in fur. Your face had the most changes, now looking very fox-like, but with enough human features to not break an uncanny valley. Then your arms and torso, they had swollen to immense proportions. If you wanted to be in a bodybuilder contest, you could easily take the gold at any local or regional, perhaps even national.
Your gaze went below the belt. Before this, you couldn’t complain about what you were born with; a little above average, but not porn star level endowments. Now there were two orbs vying for space against the thick ripped quads of your equally massive legs, and a thick sheathe rested above it. That primal voice in your head was getting stronger as you saw the tip of a very large, very thick, red cock begin to emerge. You watched on in awe for over a minute as it grew bigger and bigger, thicker and thicker, until it stopped just shy of kissing between your huge pecs.


Then there was a knock on the bathroom door. “Are you okay, sweetie?” Your mom’s voice called. “You were fast asleep when I got home, and I didn’t want to disturb you.”
That was when your mind came back into control. You let out a small grunt as there were several cracks of bone, your form shrinking back, the fur receding behind to reveal your skin.
“Sweetie.” You hear your mom try the handle as your mouth reverts back to a human form.
“Yeah, mom.” You say in a hurry, your hand pushing against the door to stop her from walking in. “I think the pizza wasn’t cooked properly.”
There is a sigh of relief. “Okay, well try and get some sleep. Hopefully you’ll be alright for seeing your friends this weekend.”
“Yeah…” You nod, hoping she’ll go to bed already. “Good night, mom.”
“Good night, dear.”
You listen for her footsteps and the shutting of her bedroom door before letting out a sigh of relief. You take another glance at the mirror on the medicine cabinet. I was harder to see as the light wasn’t turned on, but you appeared to be you again. Hoping that it was all just a weird dream, you made it back to your bed and lay down, missing that your boxers were shredded to pieces on the floor. You scratched an itch on the back of your neck, unable to know that the base of your hair had a faint orange tint. You lay on your side, quickly returning to sleep. Your bed frame creaked a little, realising better than you that you had kept some of your increased height and muscles. You thought it was just all a fever dream, but that would be disproven only one day later…
