You get home and head to your room. You walk past your younger brothers room, his door is closed and you can hear the faint sound of moaning through the door. The little perv is jacking off again, which means he's got your laptop. You consider going in and taking it back but you've made that mistake before and you don't need to see his unit again. You get into your room, throw the bag from the store down onto your bed, and sit at your laptop-less desk. You sit, trying not to hear what's happening through the paper thin wall that separates your room from his. You thought when your older brother Chris moved out and you got his room, you'd be done hearing this. You turn away from the wall and stare blankly at your bed and the socks peaking out of the bag laying on it.
You feel a wave of embarrassment wash over you, how could I have been so stupid to have bought "magic" socks. They're not even a style you like, so when they inevitably don't have any magic you won't even want to wear them. Maybe if no one can see them, you think, you'll wear them. From your chair you look into the rooms small closet, which is still half full with your Chris' things. On the top shelf sat a pair of his old high top shoes. While you were unsure if they'd fit, at least you'd get an idea of how much of the socks they'd cover. You get up and grab the shoes, sit back down in the desk chair and slide them on. They're not a great fit, however, you can see they cover quite a bit of sock. You'll have to pick up a pair, you think to yourself. You want to get a better view of how they look on you. Your room doesn't have a full length mirror so using the chair as a step you hop up on your dresser.
You're not yet aware of the changes that have started as you balance on the edge trying to get a steady view of your feet and legs. You don't notice that you're growing from 5'-7 up past 6'. You don't notice your muscles growing and firming up, or your hair shortening to a buzz cut. You're trying to figure out where you can get a cheap pair of high tops, when you start to notice how tight your pants and shirt have gotten. Just then your head hits the ceiling, surprising you because you hadn't moved it. The button pops open on your jeans and started you fall off the dresser hitting the ground hard. You hear Your younger brother laugh and yell "dweeb" at the wall.
You're slow to recover your wits as you lay on the ground. The pain coming from your waste is getting worse, so you begin to struggle to kick off your jeans. The fabric is already too tight, so panicked you rip them off. The elastic band on your underwear is also at its breaking point and gives without needing much encouragement. Without any hesitation you work your tshirt off, leaving you laying naked from the shoes and socks up on your floor. You lay there for a moment catching your breath before starting to examine your now unfamiliar body. You don't have abs, your hands aren't this big, your penis use to be 4" now it looks half as big. You begin to panic, you struggle to your feet and look at the mirror. Staring back at you is your 19 year old brother Chris.
