You spend a couple of hours exploring your new body in detail, mostly discovering that your new sexual equipment is like the Energizer Bunny - it just keeps going and going. Or coming and coming, in this case. Thirty or forty years as a beautiful young teenager who's hung like a horse? This deal seems too good to be true! And you thought demons were all evil. When Runt gets back from his vacation, you are going to give him a big kiss!
All of that exercise has given you quite an appetite, not to mention made a real mess of your sheets. There's not much in the apartment, so you decide to go out for a burger. You head for the door and almost have it open before you realize a couple of things - you are still naked, and pretty messy. You also forgot your wallet.
Being naked feels so natural that you have to force yourself to put on clothes. That could be awkward if you forget and go out. It takes some searching, but you find some old sweatpants and a jacket that you can wear on this much smaller body without looking too bad. Doubling up thick socks lets you get away with wearing a pair of sneakers that used to be too tight.
You grab your wallet and keys, and then head outside. Only to nearly run into the kid from the apartment next door and a couple of his freinds. They are about your new age of 15, smoking cigarettes. You struggle to remember the neighbor kid's name. Jack. They look at you in surprise. "Yo, dude. Who are you?"
